5 Requirements for Modern Insider Threat Detection Tools

The menace of insider threats is an ever-present concern for organizations. These threats, emanating from within, necessitate a sophisticated defense strategy underscored by advanced insider threat detection tools.

Why Modern Insider Threat Detection Tools are Needed

Insider threats present a significant challenge in cybersecurity, with trusted employees often posing risks due to their privileged access within organizations. The complexity surrounding access privileges and entitlements further complicates the task of monitoring and managing these permissions effectively. Unlike external cyber threats, which attack from outside the organization, insider threats require an inside-out perspective to be properly addressed.

According to a recent Cybersecurity Insiders report, insider threat incidents have seen a notable 74% increase, with approximately 50% of organizations experiencing at least one such incident. These incidents can have tangible business impacts, including data exfiltration and theft of sensitive data (such as intellectual property (IP), customer data, personally identifiable information (PII), and healthcare information protected by HIPAA), and other potential breaches.

The repercussions of insider threat incidents extend beyond immediate data loss. They can inflict damage on an organization’s reputation and brand trust, leading to long-term consequences and a loss of customer trust. Moreover, insider threats can have severe financial implications, potentially resulting in drops in stock prices and significant financial damages arising from IP theft or data breaches.

Challenges Faced by Insider Threat Teams

Insider threat teams grapple with challenges stemming from siloed solutions and gaps in traditional tooling. Tools such as User and Entity Behavior Analytics (UEBA), Data Loss Prevention (DLP), Privileged Access Management (PAM), Endpoint Detection and Response (EDR), and traditional Security Information and Event Management (SIEM) are often deployed in isolation, creating data silos and hindering effective threat detection.

Siloed systems, designed to address specific facets of insider threats, lack the necessary context when evaluated in isolation. This results in a deluge of alert triage, false positives and lengthy investigations, diverting valuable resources away from real threats that pose the greatest risk to the business. Standalone UEBA solutions, for instance, often lack the comprehensive view needed to accurately identify insider risks.

Moreover, traditional DLP solutions tend to be reactive rather than proactive in their approach. Instead of anticipating and preventing insider threat activities, they primarily function in an incident response capacity, reacting only after a breach has occurred. This reactive stance leaves organizations vulnerable to insider threats, with potentially devastating consequences.

Insider threat teams face a unique challenge compared to their Security Operations Center (SOC) counterparts. While they must uphold the privacy of employees, they must also ensure the security posture of the organization. This delicate balancing act requires tight partnerships with HR, Legal, line of business owners and other stakeholders. However, this collaboration becomes increasingly challenging when insider threat teams are inundated with low-fideilty alerts and irrelevant cases, eroding trust with business counterparts and impeding effective threat mitigation efforts.

5 Essential Requirements for Modern Insider Threat Detection Tools

Fortunately, advancements in data science have paved the way for a new breed of insider threat detection tools that address the shortcomings of traditional approaches. Here are five indispensable requirements for modern insider threat detection tools:

1. Complete Visibility and Breaking Down Silos: Modern insider threat detection tools should seamlessly ingest, filter, route, normalize, and analyze diverse data sources, ensuring complete visibility and breaking down silos within organizations. This comprehensive approach enables the identification and response to threats more effectively, eliminating the need to bootstrap various security tools together.
   • Gone are the days where organizations relied on external vendor services or endured long wait times for data connector integrations. Instead, modern tools should handle any security or non-security data, regardless of format, source, or location, in a cost-effective and efficient manner.
   • The ability to ingest any data format, normalize it, enrich it, and link it to other data is crucial for readiness in advanced analytics. Additionally, filtering and routing data play a pivotal role in reducing cost inhibitors associated with bringing in the right telemetry. This approach ensures organizations maintain full control of their data fabric, storing non-critical data cost-effectively while making it available for searching when necessary.
2. Contextual Insights and Real Indicators of Risk: For insider threat detection tools deriving context is paramount for accurately identifying potential risks. This involves cross-validating behavioral anomalies against supporting telemetry, enabling organizations to put deviations into perspective and take appropriate action. 

Here are some key indicators of risk that provide valuable context:

• Peer Group Analysis: Comparing an individual’s behavior to that of their peer group baseline is a powerful method for identifying anomalies. For instance, unusual activities such as sending information to personal email accounts, accessing files beyond their typical scope, or logging in at unconventional times or locations can raise red flags. UEBA (user and entity behavior analytics) can encompass endpoint and network telemetry that is factored into peer group baselines. 
• Identity and Access Analytics: Understanding what data and resources an individual has been accessing is crucial for assessing risk. By evaluating their privileges to access critical or sensitive data, organizations can identify potential insider threats more effectively.
• HR Employee Sentiment: Monitoring HR data and employee sentiment can provide valuable insights into their state of mind and potential motivations for insider threats. Factors such as receiving poor performance reviews, experiencing personal difficulties like divorce or financial issues, or exhibiting signs of dissatisfaction or job-seeking behavior can signal heightened risk.

By incorporating these contextual insights and real indicators of risk into insider threat detection strategies, organizations can enhance their ability to identify and mitigate potential insider threats effectively.

3. Streamlined Investigations: Beyond detection, tools should facilitate case creation and investigations, empowering analysts with AI-assisted capabilities and federated search functionalities. This streamlines the investigative process, enabling faster response times and more efficient threat mitigation.
4. Customization and Flexibility: Tailoring insider threat tools to unique organizational requirements ensures alignment with specific risk tolerances and business demands. Customizable machine learning models, response playbooks, and risk scoring mechanisms enable organizations to adapt their security strategies to evolving threats.
5. Full Privacy Protection: Adhering to data privacy laws and upholding individual rights is paramount in any security initiative. Robust privacy measures such as role-based access controls ensure that sensitive information remains protected, thereby fostering trust and compliance within the organization. This should include:
   • Data masking and obfuscation 
   • Dashboard privileges and granular access controls so data is limited by the principle of least privilege for a small subset of authorized users.
