Insider threats are becoming one of the most overlooked risks within enterprise environments, especially in SAP systems where critical financial, HR, and operational data lives. It’s not always a rogue employee; sometimes, it’s a well-meaning user who clicks the wrong link or a contractor with just a little too much access.
These incidents are rising fast, with costs reaching over $11 million on average and nearly 7 out of 10 organizations seeing an uptick. In SAP landscapes, where access often spans across multiple integrated systems, just one misconfigured role can open the door to serious damage.
Managing that risk starts with understanding who has access to what and making sure it’s always appropriate, secure, and well-governed.

- Defense with Layered Framework
- Access Governance is the SAP foundation
Breaking Down the Insider Threat Types in SAP Landscapes
Insider threats often hide in plain sight, disguised as routine logins or trusted roles. Understanding who poses a risk and how they operate is the first step to controlling internal exposure. These insider threats typically fall into four categories.
- Malicious Insiders
These are individuals who intentionally exploit their access to harm the organization. It could be a disgruntled employee, a contractor with a grudge, or someone acting on behalf of a competitor or foreign entity. Their actions ranging from data theft to financial fraud are often calculated and difficult to detect because they mimic legitimate behavior.
- Negligent Insiders
The most frequent, and arguably most underestimated. These are users who, often unknowingly, put systems at risk. Using weak passwords, mishandling sensitive data, or falling for phishing emails such mistakes account for more than 60% of insider breaches. The danger here isn’t intent, it’s lack of awareness and poor digital hygiene.
- Compromised Insiders
When attackers gain control of a legitimate user’s credentials, they operate under the radar. These breaches often begin with phishing or malware and result in external actors gaining insider-level access, an especially dangerous scenario in SAP landscape where one login can unlock many systems.
- Third-Party or Partner Threats
External users like vendors, consultants, or service providers may be given system access for collaboration or support. If their access isn’t tightly restricted or monitored, they can unintentionally or deliberately introduce risk. These users often bypass internal controls and become blind spots in the security posture.
How Insider Threats Target SAP Systems
Insiders leverage a variety of tactics to exploit vulnerabilities within SAP systems, many of which stem from legitimate access rights that are poorly governed. These attack vectors often appear routine on the surface, but they carry the potential for serious damage when unchecked.
Below are key threat categories and how they typically unfold:
- Unauthorized Data Exfiltration
- Downloading large volumes of customer or financial data from SAP modules
- Running unusual reports or exports outside of regular business hours
- Sharing files with unauthorized external parties or saving to unapproved locations
- Fraudulent Transactions
- Creating fake vendors and approving illegitimate payments
- Altering purchase orders or payroll entries for personal gain
- Exploiting Segregation of Duties gaps to execute and authorize the same transaction
- Privilege Abuse & SoD Violations
- Assigning elevated roles to oneself or others without approval
- Accumulating conflicting roles over time due to poor de-provisioning practices
- Modifying SAP configuration settings to override controls
- Sabotage of Systems or Data
- Deleting master records or altering business-critical configurations
- Introducing malicious code or scripts to disrupt operations
- Targeting integrations between SAP and third-party systems to break workflows
- Intellectual Property Theft
- Extracting proprietary designs or product blueprints from SAP PLM
- Accessing project data unrelated to the user’s role or responsibilities
- Using trusted access to funnel sensitive information to outside competitors
Building an Effective Insider Threat Defense Framework
Insider threats can’t be stopped by technology alone. A layered strategy that combines user awareness, process discipline, and smart controls is essential for SAP landscape.
Below are key practices that help form an effective defense framework.
- Cultivate a Security-Aware Culture
Employees remain one of the weakest links in the security chain. Regular training and pre-employment screening help reduce the risk of accidental or intentional misuse.
- Enforce Least Privilege Access
Users should only have the access necessary for their role. Tight role definitions and automated provisioning workflows prevent access creep over time.
- Implement Strong Authentication & Contextual Controls
Multi-factor authentication and context-aware access policies limit exposure. Granting access only during specific times or from trusted locations adds another layer of security.
- Continuously Monitor for Anomalies
Monitoring user behavior helps detect risky patterns early. Tools like UEBA can identify deviations that signal insider activity before damage occurs.
- Deploy DLP and Real-Time Alerts
Data loss prevention tools can block unauthorized transfers. Real-time alerts notify security teams of suspicious actions, such as privilege escalations or large data exports.
- Conduct Regular Access Reviews and SoD Audits
Periodic access certification ensures permissions stay aligned with job duties. SoD audits reduce the chance of fraud by catching conflicting role assignments.
- Establish an Insider Threat Response Plan
A defined response framework enables quick, coordinated action. It should include investigative procedures, evidence handling, and communication protocols across departments.
Strengthening SAP Security Through Access Governance
Access governance plays a critical role in minimizing insider risk across SAP environments. It ensures users receive only the access required for their roles, reducing the chance of privilege misuse and improving audit readiness.
In many SAP landscapes, access is managed separately across modules like S/4HANA, Ariba, and SuccessFactors. Without centralized visibility, it’s easy for a user to end up with permissions in one system that, when combined with another, unintentionally creates a Segregation of Duties (SoD) conflict, such as the ability to both create and approve a purchase order.
Centralized governance addresses this by unifying role definitions, enforcing SoD policies across systems, and proactively detecting risky access combinations. For SAP security teams, it’s a foundational control that directly supports both compliance and insider threat prevention.
UAS in Action: Neutralizing Insider Threats at the Access Layer
Diligent Global’s User Access Shield (UAS) is purpose-built to help enterprises detect, prevent, and contain insider risks at the access level where most threats originate. Built natively on SAP BTP, UAS automates access governance, enforces security controls, and gives enterprises full visibility across their SAP ecosystem.
UAS helps eliminate insider risk through the following capabilities:
- Unified Access Governance Across SAP
UAS centralizes provisioning, de-provisioning, and role management across SAP S/4HANA, Ariba, Concur, SuccessFactors, and more. By eliminating fragmented access silos, it ensures consistent SoD enforcement and closes blind spots that insiders could exploit.
