Solving Complex SAP Data Security Challenges with Dynamic Data Masking

By Michael Cunningham • June 2, 2021

Here are two use cases that might sound familiar… 

While organizations spend millions combatting external threats, for example, hacking, phishing, and ransomware, we at Appsian Security have found most data security use cases are focused on data governance across the enterprise. Simply put, what can someone access depending on where they’re located, what business unit they belong to, or even what time of day it is? Ensuring SAP data security policies are followed without over-restricting access or hurting productivity is a serious juggling act. Sadly, most organizations get it wrong. Fortunately, the solution can come down to a concept as simple as data masking – what, when, and how?  

I had the opportunity to learn about two specific use cases (from Appsian customers) and how they used dynamic data masking to protect sensitive data—all without adding bottlenecks or complexity to their organization.  

Transportation Company Use Case    

While many industries struggled through the COVID-19 pandemic, a transportation and rail company based in Canada thrived. This was due to being a critical delivery component for many supply chains. The company had to transform its office-based workers into a flex-work model (hybrid workforce) and hire additional employees for fieldwork. The hybrid workers needed to continue their day-to-day managerial tasks, which contained sensitive information that the company was not comfortable exposing outside its secure corporate office. Securing access to this data was further complicated by remote workers traveling from city to city and logging into the self-service SAP modules on mobile devices from wherever they had a Wi-Fi connection.  

The company turned to Appsian to enable a dynamic data masking solution by leveraging contextual access controls that determined which sensitive data fields and Tcodes employees could access based on attributes such as location, IP address, time, data sensitivity, and more.

International Consumer Packaged Goods Use Case    

Where one company was dealing with multiple employee/user locations, an international consumer packaged goods company was dealing with multiple office locations around the world, each with its own installation of SAP. The company needed the means to protect sensitive personal data (stored in 1 of 5 unique SAP systems) while abiding by each location’s unique PII protection requirement (GDPR, PIPA, LGPD, etc.).   

For this unique situation, the company needed a centralized data masking solution that could follow each location’s unique governance policies. All while being flexible enough to manage scenarios involving multiple locations and protecting sensitive data in production and non-production environments.   

For example, a US-based employee could access the SAP system in the South American office. Yet, the dynamic policy could mask certain pieces of information or Tcodes because of the user’s nationality. The user’s location is from a legitimate IP address, but their nationality forbids them from accessing certain personal or sensitive information due to international regulations or company policies—even if that user can access that information in their own instance of SAP.    

Protecting SAP Data with a Dynamic Data Masking Solution   

The key to a successful dynamic data masking solution is the use of contextual access control policies (ABAC). ABAC allows companies to work in conjunction with existing roles-based controls (RBAC). Without it, neither one of these companies could successfully enable data masking without extensive customization, resulting in an unscalable ad-hoc solution.    

Appsian Security Platform’s (ASP) dynamic data masking capabilities provide fine-grained control over which sensitive data fields can be masked for any specified user in the context of any situation. For example, ASP allowed both companies to:   

  • Centralize data masking enforcement throughout ECC and S/4HANA with a single ruleset.   
  • Deploy dynamic policies that account for risk based on the context of access, such as location, IP address, time, data sensitivity, and more.   
  • Protect sensitive data in production and non-production environments.   
  • Align SAP data masking controls with existing governance (corporate) policies.     
  • Mask sensitive PII based on the data subjects’ residency (country/nationality).    
  • Mask data fields in transactions (Tcodes) that are unnecessary for a role.

How Appsian Reduces Risk in SAP Procurement Transactions

By Michael Cunningham • March 24, 2021

The sheer breadth and complexity of the procurement process can make maintaining effective internal controls difficult. Organizations must implement business process controls to ensure that employees only have access to SAP procurement transactions appropriate to their role and that the activity within these transactions falls in line with their established business policies. Having tightly aligned controls that prevent policy violations in the first place is critical to reducing the level of accepted risk in procurement business processes.

And this brings us to a key challenge in SAP procurement processes. Relying solely on SAP’s static role-based access controls (RBAC) has its limitations. Without the ability to consider factors beyond a user’s role and privileges, preventive controls may be impractical in certain scenarios, forcing reliance on detection and remediation in hindsight.

Enforce SAP Procurement Transaction Policies with Dynamic Access Controls

With the dynamic nature of procurement processes, extending your business process controls strategy to include data-centric and context-aware functionality can significantly reduce your risk exposure. Organizations using SAP ECC and SAP S/4HANA can strengthen policy enforcement by leveraging dynamic, attribute-based access controls (ABAC). Appsian extends SAP’s existing security model by enabling a fine-grain approach that shrinks the gap between business goals and security controls.

Let’s look at some specific use cases across SAP procurement transactions to demonstrate how Appsian can reduce SAP business process risks in today’s dynamic access environment.

Dynamically Controlling Purchase Order Creation

Purchase order creation is an important procurement transaction that should be controlled by an assigned threshold level and approval limits. Appsian allows you to easily manage risks associated with the purchase order process by extending dynamic controls into SAP based on factors such as PO dollar amount, location, time of day, and more.

For example, let’s look at a couple of employees:

Employee Total PO Threshold Create POs when Remote?
George Up to $5,000 No
Gracie Up to $25,000 Yes. Between 8 am-5 pm

You can allow George only to create POs that do not exceed $5,000 in value. He is also blocked from creating POs outside of the corporate network. For Gracie, she has the company’s approval to create POs up to $25,000 and can do it when working remotely as long as it is during normal business hours of 8:00 am to 5:00 pm.

Dynamically Enforce Segregation of Duties

During the procurement business process, there is a need to control the PO’s life cycle using Segregation of Duties (SoD). That means the same person can’t perform PO creation and GR (Goods Receipt) posting followed by IR (Invoice Receipt) posting.

Segregation of Duties policies that rely on static role-based rules can create unwanted business risk because they lack visibility into attributes that define actual conflicts of interest. This gap also carries over into SoD audit logs, resulting in excessive false positives when SoD exceptions have been made.

Appsian allows you to stop unauthorized user activity in real-time using a data-centric approach to enforce SoD controls. Our preventive SoD controls correlate user, data, and transaction attributes, along with identified SoD conflicts, to block conflicting transactions at runtime – even if they have the role-based privileges to perform the transaction.

This approach can add flexibility to procurement processes by allowing users with SoD exceptions to perform conflicting transactions that do not pose actual SoD violations while preventing those that do. The preventive SoD controls can also act as a safeguard to stop any SoD violations that may originate from privilege creep, such as a user changing roles without prompt deprovisioning of old privileges.

Limit Access to Sensitive Data by Masking with Conditions

Because the SAP procurement process touches different departments, it’s important to ensure that users do not have access to data or transactions outside of their roles and responsibilities. From protected PII to privileged financial information – this data carries risks that organizations must address.

Alas, there are no masking capabilities available out of the box in SAP. As a result, privileged users can access sensitive data fields even when access is unnecessary. This kind of unchecked data exposure leaves a massive threat surface that is vulnerable to exploitation and leakage.

Appsian’s Dynamic Data Masking provides SAP customers with fine-grained control over which sensitive data fields they can mask for specified users in the context of any situation. For example, you can decide to mask PII, account names, account numbers, etc., if access comes from an unmanaged device, unknown IP range, or outside typical working hours. Likewise, you can easily mask sensitive data in transactions where exposure is unnecessary for a certain role to do the task at hand.

Appsian: The Dynamic Approach to Reducing SAP Procurement Risks

Managing SAP procurement transactions exist in the overall category of reducing SAP business process risks. It’s a persistent challenge facing organizations of all sizes.

How Appsian Improves SAP Segregation of Duties Violations Management

By Ryan Quinonez • March 22, 2021

From stopping fraud, theft, and errors to preventing SOX compliance violations, SAP Segregation of Duties (SoD) plays a lead role in minimizing business risk. Organizations must continuously iterate their internal controls to ensure their SoD strategy is effective; however, we all know this is easier said than done. 

Finite Resources & Manual Processes Can Only Address So Much

With existing capabilities, audit preparation and reporting are manually intensive processes that deliver an outdated snapshot of risk. Time and effort are wasted investigating immaterial events (i.e., false-positives, non-financial activity) because audit logs miss relevant details. Furthermore, manual analysis can be prone to errors, unscalable, and increasingly costly.

Due to resource-intensive audit processes, most organizations can only review a fraction of their SoD audit findings. This limited sample scope, typically between 3-8%, leaves the vast majority of risk unaddressed. While the sample may indicate control effectiveness, significant material risks may go undetected, and confidence will be curbed. 

Leveraging Technology to Reduce Your SAP SoD Risk Exposure

Existing SAP SoD audit logs will show transaction activity but lack the data-level granularity to identify and filter out false-positive SoD violations. Manual investigation and correlation must be performed to do this – adding overhead, slowing the reporting process, and making it more difficult to prove compliance. 

The bottleneck stems from technology and dictates unscalable processes. One approach to overcome this challenge is to adopt data-centric logging, which provides relevant details beyond roles and transactions – enabling customers to automate the majority of manual investigation and correlation efforts. From here, organizations can shift their valuable human resources towards remedial activities to further reduce SoD risks. 

How Appsian Improves SAP Segregation of Duties Violations Management

Delivering data-centric logs paired with contextual information, Appsian360 provides visibility into SoD violations with far greater detail than what is possible with existing transaction-level audit logs. This additional information enables customers to eliminate false-positives automatically, view actual SoD violations, and prioritize events based on relevant details (e.g., dollar amount, time/location performed, etc.)

Leverage data-centric visibility to streamline SAP Segregation of Duties:

  • Uncover 100% of SoD violations with data-centric continuous controls monitoring.
  • Capture actionable details that would previously require manual investigation.
  • Gain an always current view of SoD risks with continuous audit capabilities.
  • Prioritize investigation & remediation activity by eliminating wasted effort on immaterial events.
  • Simplify proving compliance with granular visibility and contextual information that is missing from existing audit logs.
  • Get a Demo of Appsian360 and See for Yourself

As the burden of SAP SoD compliance grows, organizations must look towards technology to help automate tedious manual processes and strengthen internal controls. At Appsian, we’ve built our solutions with this need in mind, delivering a platform that enables SAP customers to do more with less.

Implementing Dynamic SAP Data Masking in ECC & S/4HANA Using Appsian

By Scott Lavery • March 18, 2021

2020 brought about a reckoning for organizations that were slow to adopt strong data privacy and data loss prevention strategies. As users went remote, the networks and devices used to access SAP financial data became a liability – and organizations were sent scrambling for solutions to their newfound dynamic access demands.

Out-of-the-Box SAP Data Protection is Not Enough

In order to prevent data exfiltration and general over-exposure of enterprise data, the use of SAP data masking has grown in popularity. Unfortunately, customers have no out-of-the-box solutions for SAP data masking. In fact, the entire SAP security model hinges on static, role-based controls that offer little to actually protect the data inside the transactions that the access controls are designed to govern. In many cases, a user who has access to a transaction has access to a wide range of data within that transaction that simply isn’t necessary – providing opportunities for misuse.

To make matters more complicated, if an organization were to undergo a large-scale SAP data masking project, the sheer amount of custom development would prove to be a significant hurdle and nearly impossible to scale effectively.

Appsian Offers a Centralized, Scalable Alternative

To offer SAP ERP customers a scalable data masking solution, the Appsian Security Platform (ASP) features dynamic data masking capabilities that enable fine-grained control over which sensitive data fields customers can mask for any specified user and in the context of any situation. By implementing a full or partial mask to a data record, ASP minimizes the risk of a data breach and fulfills encryption and anonymization mandates imposed or implied by regulatory bodies. 

Unlike most off-the-shelf masking solutions, Appsian uses a single ruleset to define and mask data across the entire application:

  • Centralize SAP data masking enforcement with a single ruleset
  • Deploy dynamic policies that account for risk contexts such as location, IP address, time, data sensitivity, and more 
  • Protect sensitive data in production and non-production environments
  • Implement masking without requiring additional customizations to SAP
  • Filter out sensitive data at the presentation layer, resulting in no additional maintenance requirements for updates

Why Appsian is the Essential Dynamic SAP Data Masking Solution

Simply put, when you are trying to protect data without overly-restricting access, then there is no alternative to leveraging a dynamic SAP data masking solution. Because the context of access plays such a critical role in defining risk, being able to apply full or partial masks based on context is the only real way to balance data protection and productivity. 

In addition, Appsian uses a “one to many” approach for creating policy-based data masking rules. This enables customers to quickly scale SAP data masking without extensive development effort at implementation or reconfiguration efforts for policy updates. 

Example Use Cases for Dynamic SAP Data Masking

  1. Mask PII of Customers in SAP CRM Based on their residency
    GDPR Compliance – Ex: Mask PII Data if Customers’ Address is in the EU
  2. Mask & Lock Bank Account Fields After Hours
    Fraud & Theft – Ex: Insider Changing Data at Night Before Pay-Run 
  3. Obscure Data Fields in Transactions that are Unnecessary for a Role 
    Data Minimization – Ex: Customer Support Seeing Financial Spend, Pricing Info
  4. Prevent Remote Access of Unpublished Financial Information
    Risk Mitigation – Ex: Mask Data when Access Occurs After Hours or Remote

How IT Can Use ERP Data to Become a Hero to their Business Stakeholders

By Michael Cunningham • November 4, 2020

When business stakeholders come to you looking for answers, having visibility and context around ERP data access and usage gives you the actionable insight necessary to provide value.

As a leader of Enterprise Applications, customizing legacy ERP applications like PeopleSoft, SAP ECC, Oracle EBS, etc., to meet your business’ exact process specifications can leave you between a rock and a hard place. The more customized your ERP applications get, the more your business stakeholders love it, but the complexity around application support and maintenance also increases. That being said, accepting more complexity is just part of the job, because after all, your most important role (in the eyes of others) is providing timely and accurate resolution to inquiries or incidents from your business stakeholders

You know the drill: members from various business units come to you requesting help for a particular incident or an anomaly they spotted. It’s up to your team to provide a resolution in a timely manner. And that’s where the trouble begins. Many incidents require hours, weeks, and even months to research and resolve. It’s hard to provide excellent customer service to the lines of business when your team is facing major obstacles to resolving incidents in a timely manner.  

What if I told you there’s a way to enable your team to spend less time researching an issue (or no time at all) and produce faster results while providing better value for the various business leaders and their teams? 

Three Major Obstacles to Timely ERP Incident Resolution 

You’re the last person who wants to hear or say, “well, that’s just [insert ERP app name here].” But that’s one way you can sum up the limitations and obstacles your team will immediately encounter.  

Here’s a simplified view of that process from the perspective of PeopleSoft. Somebody from a line of business will contact a member of your Sys Admin team and say, “Hey, this user’s account was updated (i.e., maybe they didn’t get their paycheck), or there was some sort of anomaly in the execution of a typical business transaction (i.e., vendor didn’t get paid, etc.). We don’t know what it is, and the functional user(s) say it wasn’t them. We’re not sure what happened. Can you guys look into this? That would be great.”  

This incident kicks off your process flow to find a resolution. Then come the obstacles: 

Obstacle 1Legacy ERP Logs Can’t Tell You About Data Access 

Experience says that most people who use an ERP application like PeopleSoft don’t know who’s doing what (specifically), who’s accessing what information, or most importantly – why. You probably first need to work out if this is something that the user did themselves or a hacker was able to gain access to the system – and also work out if this is an inside job or an external attack.

And while the logs can point you in the right direction, the legacy ERP logs are not designed to provide detailed information on who accessed what or even, in most cases, viewed something sensitive. This leads to major obstacle number two…

Obstacle 2ERP Logs are Disparate and Not Correlated 

ERP logs were designed for troubleshooting, not granular activity logging, which contributes to organizations and business units not knowing what their employees are doing inside the applications. When it’s time to go under the application hood and examine the native logs, another metaphor comes to mind: looking for a needle in the haystack. Here’s an example of all the native logs you might find in your instance of PeopleSoft: 

  1. App Server 
  2. PIA (Web Server) 
  3. Database 
  4. Process Scheduler 
  5. Load Balancer 
  6. Identity Provider (SAML, LDAP, ADFS) 
  7. Host O/S Logs 
  8. Firewall 

Your organization likely has more than one of these servers where these logs reside. You might have four application servers, eight web servers, and so on. Now you’re looking at finding a needle in multiple haystacks. And that data is not correlated, so there is little relative context that can enable your investigation. 

Here’s a nerdy example using the App Server and Web Server logs. On the Web Server, you cannot identify the person who logged in because you don’t know the OPRID. All you have are an IP address and a timestamp. You need to go to the App Server and review the OPRID, timestamp, and IP address on login or log out and attempt to correlate that information with similar information on the Web Server.  

Obstacle 3: Log Data is Not Enriched with Any Context That Makes It Actionable 

Once your team has collected data from the logs and assembled material from other sources, the final step is to interpret everything and make a best guess so an action item can be established. How actionable is having a collection of raw data such as IP addresses, user IDs, location of devices, completed transaction, etc., if you’re not able to place that data into a human context?  

Let’s take the example of “Jim” and the incident involving him not receiving a paycheck. The raw ERP data shows that Jim’s credentials accessed pages containing personal information and bank account information several times over a period of time. Jim, the human, denies that he made any changes to the data on those pages, so the paycheck should have been routed to his usual bank account. Maybe you change Jim’s username and password and cut him another check. Was Jim trying to defraud the company and get an extra check, or was Jim’s account compromised in some way? Could a hacker have accessed Jim’s payroll data, changed the account number, received the funds, then changed the number back – getting away without a trace? Absolutely! It happens every day. If you cut Jim a new check, you fix Jim’s immediate problem, but do you understand what’s happening in your system?  

Why Appsian360 Immediately Makes You a Hero to Your Organization 

You’ve been waiting in suspense to know when IT becomes the hero – well, here it is. When the business comes to you looking for answers related to a specific incident, Appsian360 provides the quick, actionable insight necessary to provide the company with the understanding of what happened with their ERP data.  

How? Appsian360 logs granular user access to data, correlates existing ERP logs, enriches the data with contextual attributes (who, when, where, what device, etc.), and visualizes the ERP data’s access and usage on dashboards. Now your team can easily look at data access by IP addresses, user IDs, location of devices, pages accessed, etc., and very quickly understand the facts behind an incident. 

Let’s go back to Jim’s situation. With just a handful of clicks in Appsian360, you confirm that “Jim’s credentials” did indeed access and edit his personal information. Additionally, you discover that “Jim” was logging in after-hours using a foreign IP address based in another country. With a few more clicks, it’s clear that the IP address is responsible for other compromised user accounts. You didn’t just discover Jim’s breach, you now have a clear picture and a direction to fix the actual security issue – one that was growing in urgency by the day!

Without context, you lack insight. Context around data access and usage creates actionable insights. Actionable insights support the company and provide value to key stakeholders.  

Understanding user activity and data usage are precisely what the business needs – and without Appsian360, ERP logs lack insight. You can buck that trend with Appsian360.

SAP Access Control: A Beginner’s Guide to SAP Dynamic Authorization

By Michael Cunningham • October 20, 2020

As your company’s digital footprint grows, you can enhance your security posture by complementing your existing SAP Role-Based Access Controls (RBAC) with dynamic, Attribute-Based Access Controls (ABAC) to strengthen authentication and authorization. Both RBAC and ABAC are ways that organizations can control authentication and authorization, but they perform different functions across an enterprise IT stack. 

Understanding SAP Access Control Using Roles

Functionally, a role is a collection of permissions using sets, relations, and mapping that align access needs to resources based and limit access on a “need to know” basis.

RBAC involves three basic principles:

  1. Role assignment: Only users with the right login can gain access to and interact with a system or application.
  2. Role authorization: When combined with role assignment, administrators authorize a set of credentials that can gain access to and interact with a system.
  3. Transaction authorization: A user can only interact with a resource to which she is authorized through her role memberships while also limited on a “need to know basis.”

RBAC has since evolved to include “hierarchies.” Hierarchies assign different roles different levels of access. For example, a Chief Executive Officer (CEO) needs to have a lot of access to sensitive information. Therefore, the CEO role has access that also encompasses the type of access provided to the Vice President’s, line of business managers, and standard employees. However, since a standard employee is at the “bottom” of the hierarchy, RBAC prevents her from accessing the sensitive information that the CEO can access.

Enhancing RBAC by Using Dynamic Authorizations in SAP

RBAC provides a strong foundation for setting access controls. However, digital transformation changes the way people interact with data resources. Since RBAC was intended for on-premises data repositories, it creates a very strict, static set of permissions. You either have access or you don’t. 

Dynamic authorization – also known as attribute-based access controls (ABAC) – enhances RBAC by taking into account different “attributes.” Attributes are the adjectives of the access control world because they incorporate an additional description of either the user or resource.

Examples of user attributes:

  1. Department within the organization
  2. Management level
  3. Citizenship / Residency
  4. Security Clearance

Examples of action attributes: 

  1. Read
  2. Write
  3. Transfer (money)

Examples of resource attributes:

  1. Data Classification
  2. Transaction Code
  3. Document Number
  4. Plant Code

Example of environment attributes:

  1. Time
  2. Geographic location
  3. Device type
  4. Connection type

By incorporating these attributes, organizations can control user access more precisely, and with the flexibility of dynamic authorizations, better balance business and security requirements.

Achieving Dynamic Access by Using Attributes

Roles act as the foundation for providing access. If you think about it like a sentence, RBAC is the subject and verb. An IT admin has what we call “superuser” access. A simple RBAC sentence might look like this:

IT administrators can read and edit all information. 

Based on RBAC, this sentence provides so much access that an IT administrator could be a data breach risk. Whether maliciously stealing sensitive information or accidentally sharing private information, the unrestricted access means organizations struggle to restrict IT administrator access while still providing enough access for the employee to do their job. 

However, if we add attributes, or additional descriptors about how/when/where IT administrators can use their access, we limit the risk. By creating an “if-then” statement, we apply restrictions based on the defined characteristics. 

If IT administrators are accessing the database (resource attribute)
from their homes (environment attribute) then
they can read (action attribute) the information. 

By adding these attributes, we can prevent IT administrators from making changes to databases while they are at home. 

Furthermore, we can use attributes to grant access as well. Taking the same statement, let’s incorporate time of day as an additional attribute. 

If IT administrators are accessing the database (resource attribute)
from their homes (environment attribute) then
they can read (action attribute) the information,
but if they access the database
between 8 AM and 10 AM (environment attribute 2),
they can edit user data (action attribute 2)

By adding the additional environment and action attributes, you’re creating a scenario that allows IT administrators to work from home while also reducing the risk. You have created a time-bound restriction that requires them to only make user data changes during the hours of 8 AM and 10 AM if they are at home while at all other times, they can only read the database information. 

The more attributes you can incorporate, the more precisely you can define what, how, and when a user or group of users can access data. 

Creating a Robust Data Security Strategy Using a Hybrid SAP Access Control Model

As organizations accelerate their digital transformation initiatives and allow more remote access to data and transactions, they need a way to configure a layered defense using a hybrid approach to SAP access control. Starting with RBAC, organizations set the foundation of their access policies. However, by incorporating different attributes such as user, resource, action, and environment characteristics, you can more appropriately limit access to and within your SAP data.

Without a solution like Appsian, the closest and organization can come to granting dynamic access to SAP is through customization or adding roles to a user for each attribute. Both options are costly and ultimately unmanageable in the long run.

How Does Appsian Work with SAP GRC Access Control?

By Rajesh Rengarethinam • August 20, 2020

At the SAPinsider 2020 virtual conference experience, one of our product demo attendees asked how Appsian works with SAP GRC Access Control. We get this question a lot as SAP security and system professionals explore adding attribute-based access controls (ABAC) to the native SAP role-based access controls (RBAC) to streamline and strengthen access policy management and enforcement. Sometimes there is confusion about whether ABAC is enhancing or replacing their RBAC. Let’s take a quick look at how Appsian’s ABAC works with and enhances SAP GRC Access Control.  

What is SAP GRC Access Control 

Organizations use SAP Governance, Risk, and Compliance (SAP GRC) to manage regulations and compliance and remove any risk in managing critical operations. One of the SAP GRC modules that helps organizations meet data security and authorization standards is SAP GRC Access Control. This module ensures that the right access is given to the right people with RBAC. It uses templates and workflow-driven access requests and approvals to streamline the process of managing and validating user access and provisioning. Without SAP GRC, for comparison, a person is creating all the roles from scratch and assigning privileges to them.

Appsian Enhances SAP GRC with Attribute-Based Access Controls 

Appsian combines the SAP GRC role-based access controls with an attribute-based access control solution that delivers an ABAC + RBAC hybrid approach. This enhanced approach enables granular control and visibility that delivers a wide range of business benefits and lets you deploy data-centric security policies that leverage the context of access to reduce risk.  

Appsian overcomes the limitations of traditional RBAC, allowing you to fully align SAP security policies with the objectives of your business and streamline audits and compliance. 

As you can see in this illustration, ABAC begins the moment users start to access data and transactions. Where RBAC assigns access based specific roles, ABAC considers the context of access (who, what, where, when, and how) before allowing access to transactions or data. Customers can set up additional rules that allow conditional access, for example, masking specific data fields or limiting the number of transactions after a particular time of day) or entirely denying access based on factors such as an unknown IP address. 

Real-Time Analytics for SAP Security & Risk Management 

With Appsian360, our real-time analytics and reporting tool, Appsian can enhance the SAP GRC reporting capabilities with direct, real-time visibility into transaction usage, violations, and compliance risk. Additionally, customers can: 

  1. Monitor transaction usage, master data changes, and SoD violations 
  2. View actual SoD violations with user, data, and transaction correlation 
  3. Segment reports by user/data attributes 
  4. Drill down into end-user usage events 

Appsian360 provides analytical reports to drill down into end-user usage events to capture business risks and anomalies, and usage events that tie back to compliance risks.  

The ABAC + RBAC Hybrid Approach to SAP GRC Access Control 

By combining data-centric security capabilities with attribute-based policies, Appsian extends and enhances the existing SAP GRC internal access controls and improves the reporting and auditing capabilities. 

Contact us today and schedule a demo to see how Appsian can help you enforce access controls beyond the standard RBAC model of SAP.

When it Comes to ERP Data Security, Context (of Access) Matters – Appsian360 Can Help!

By Michael Cunningham • July 28, 2020

Organizations using traditional, on-premise ERP applications like SAP ECC and Oracle PeopleSoft are facing a rapidly changing reality around the collection, storage, and usage of data. Aside from the growing number of compliance regulations they need to follow, such as GDRP, CCPA, and others, they face critical visibility gaps related (explicitly) to understanding ERP data access & usage.  Especially at a fine-grained level.

This lack of visibility is exacerbated by organizations enabling remote and mobile access to their users, exposing them to a myriad of data security and compliance threats like hacking (phishing), along with fraud and theft from internal users. All of which result in the loss of millions of dollars each year.  

Fortunately, ERP applications that were once considered a “black box” can now be enhanced with the most sophisticated logging and analytics technology available on the market. Introducing Appsian360, the first and only data access and usage analytics platform for SAP and PeopleSoft.  

Why Context of User Access and Data Usage Matters  

Far too often, user behavior is a mystery, resulting in security, fraud, theft, and business policy violations. Specifically, a lack of detailed insights regarding how, when, and by whom transactions and data fields are being accessed.   

As they exist today, legacy on-premise SAP and PeopleSoft systems simply do not provide organizations the granular visibility and context of user access and data usage they need in real-time to make proactive and strategic decisions.   

“For years, organizations have been operating with limited visibility, and current threats to ERP data have made this status quo completely intolerable,” said Piyush Pandey, CEO of Appsian. “Appsian360 is about knowing who is doing what – at a very granular level.”   

With Appsian360, security and compliance leaders can drill into specific data access and know exactly who is doing what, where, and why. With that level of in-depth, contextual information, any red flag incidents can undergo a rapid response plan.   

“The beauty of Appsian360 is it’s a comprehensive solution that provides actionable insights,” added Pandey. “We know that forensic investigations and time to mitigation costs organizations countless amounts of money – and we’re pleased that Appsian360 can alleviate much of this burden.”

The RECON Bug Highlights SAP Customers’ Need for Fine-Grained Control and Visibility (Not Just Security Patches)

By Rajesh Rengarethinam • July 21, 2020

A critical SAP vulnerability (CVE-2020-6287 or RECON) was recently discovered by Onapsis, giving attackers TOTAL control of vulnerable business applications. It allows hackers to gain unauthenticated access to SAP and then create new user accounts with admin (superuser) privileges. A malicious attacker can do limitless amounts of damage with these privileges, including stealing data, changing bank account numbers, fully sabotaging systems, and more. 

RECON Shares Similarities to a Familiar Foe – 10KBLAZE 

The RECON vulnerability puts the confidentiality, integrity, and availability of SAP ERP data and processes at risk, which is very similar to the 10KBLAZE exploit from 2019. What do these two exploits have in common? Simple, they are leveraging a lack of visibility and control to be successful. There is a reason that these exploits focus on the creation of admin accounts – because once you’re an admin (legitimate or not), you have the keys to the castle. 

The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and administrators of SAP products to:  

  1. Analyze systems for malicious or excessive user authorizations. 
  2. Monitor systems for indicators of compromised accounts resulting from the exploitation of vulnerabilities. 
  3. Monitor systems for suspicious user behavior, including both privileged and non-privileged users. 
  4. Apply threat intelligence on new vulnerabilities to improve the security posture against advanced targeted attacks. 
  5. Define comprehensive security baselines for systems and continuously monitor for compliance violations and remediate detected deviations. 

The key recommendations align with the need for monitoring – monitoring systems, monitoring transactions, monitoring the creation of accounts, and (most importantly) monitoring data access and usage. This is where many customers will struggle with their SAP risk management as attaining fine-grained controls and visibility are complex, even prohibitive at times, with native functionality. This is precisely where Appsian can help. 

A Second Layer of Defense: Fine-Grained Control and Visibility 

RECON and 10KBLAZE highlight that a single, static layer of security within SAP is inadequate to combat modern-day threats. Appsian enables SAP ERP customers to layer their defenses using a comprehensive suite of fine-grained, risk-aware access controls, and continuous monitoring of data access and usage. 

Here are Appsian’s recommendations to minimize your attack surface and the risks posed by RECON – and future vulnerabilities like it (in addition to recommended security patches). 

Attribute-Based Access Controls (ABAC) Are Essential in a Dynamic Environment  

RECON and 10KBLAZE take advantage of vulnerabilities in the open, internet-facing SAP components (think remote access). The Appsian Security Platform (ASP) uses attribute-based access controls (ABAC) to implement data-centric, “risk-aware” controls. ABAC prevents specific transactions like user provisioning when access originates from untrusted IP addresses (or IP addresses outside your whitelist), certain geographic locations, outside work hours, mobile devices, and many other contextual attributes. The bottom line is that Appsian can stop the creation of a user account (or changes in privileges) if access is coming from outside the corporate network. Fine-grained policies can be implemented to block high-risk activity, such as those matching the RECON attack patterns. 

Visibility into Data Access and Usage is Essential for Combatting Configuration Gaps 

Both RECON and 10KBLAZE center around the unauthorized creation of high privileged user accounts. Appsian360, the latest real-time analytics solution by Appsian, captures and visualizes data access and usage, which is essential for monitoring user provisioning activity like user creation/deletion and role/profile changes. Appsian360 can detect and alert organizations at the point of initial account creation, minimizing the damage by reducing how long a threat goes undetected.     

Appsian360 can also detect suspicious transaction activity if the compromised and illegitimate accounts are not addressed at the point of creation. Furthermore, this creates an audit trail that acts independently from existing SAP logs and can expedite breach forensics activities. 

This detailed insight can make a positive impact on a company’s SAP risk management.

Prepare Yourself for the Next Critical SAP Vulnerability – Layer Your Defenses (While and After you Patch Your Applications) 

RECON isn’t the first critical vulnerability to affect SAP, nor will it be the last. While there are security patches available to keep their ERP systems safe, these can take time (and resources) to implement, which results in significant downtime of production systems. Furthermore, the time to apply the patches depends on the complexity and the components involved. By all means, stay up to date on system updates, but bugs like RECON and 10KBLAZE serve as a reminder that patches aren’t enough to protect critical SAP data. 

Talk to the SAP Risk Management and Security Experts at Appsian today to discuss how your organization can address the risks posed by RECON and other vulnerabilities.
