Improving insider threat detection

Detecting and proactively preventing external cyberattacks is a focus for security operations (SecOps) teams, but insider attacks also pose a risk. In fact, nearly 75% of data breaches are caused byinsider threats. Whether insiders maliciously intend to attack organizations, neglect to protect systems or have their credentials stolen, identifying and preventing insider threats is yet another cybersecurity challenge facing organizations. Companies must proactively find ways to handle insider threat detection to truly protect themselves.

Types of Insider Threats

There are three types of insider threats:

  1. Malicious insiders: Individuals within the company who intentionally use or give their credentials to someone to cause harm to the organization.
  2. Negligent employees: Employees who accidentally neglect to protect their login information, fall for a phishing attack or are otherwise unaware that they are leaving the organization vulnerable.
  3. Stolen credentials: This goes hand-in-hand with negligent employees. Credentials are often stolen (or if phished, given) to malicious cybercriminals outside of the organization who then wreak havoc on systems by bypassing automatic perimeter defenses.

Organizations often have trouble discovering these threats because established insider threat detection methods are inefficient and faulty. Researching and validating potential insider threats requires extensive effort, and in many cases, SecOps teams are already spread too thin handling copious amounts of alerts from disparate security tools. While these disparate tools are necessary to verify potential threats, analysts must dive into each tool individually to fully understand the incident.

Additionally, organizations find that detecting insider threats can be incredibly challenging because the threat activity frequently emulates normal behavior. Real credentials are used, and the normal signs that would indicate an “attack” don’t occur so systems don’t alert SecOps. What’s more, attacks are normally spread out across multiple systems. These elements make it particularly difficult to detect and understand the scope of an insider attack.

How can organizations improve insider threat detection?

Security orchestration, automation and response (SOAR) is a solution that organizations need to improve insider threat detection. SOAR allows SecOps teams to use orchestration to integrate multiple tools for rapid insider threat detection and response, no matter the type of insider threat. Security automation then allows workflows to trigger automatically, pushing threat incidences through the entire investigation and response process and only alerting teams when human intervention is required. This helps to thwart the never-ending stream of security alerts that make it challenging for organizations to stay ahead of threats. SOAR solutions significantly reduces mean time to resolution (MTTR), which is key to minimizing the damage of insider threats, and helps protect your organization by identifying and stopping insider threats before they cause major damage.

Integrating your security tool set gives SecOps teams exactly what they need to have a complete understanding of all insider threat alerts. Plus, automating portions of the threat response process makes the entire security infrastructure more effective without adding overhead.

With a SOAR solution centralizing insider threat alerts and all other types of security alerts, SecOps teams have the comprehensive information they need to understand security within their organization, helping them prepare for, defend against and better understand potential new threats before they occur.
