How To Protect Against an Insider Attack: Best PracticesYou can take the following steps to help reduce the risk of insider threats:
Insider Threat Detection SolutionsInsider threats can be harder to identify or prevent than outside attacks, and they are invisible to traditional security solutions like firewalls and intrusion detection systems, which focus on external threats. If an attacker exploits an authorized login, the security mechanisms in place may not identify the abnormal behavior. Moreover, malicious insiders can more easily avoid detection if they are familiar with the security measures of an organization. To protect all your assets, you should diversify your insider threat detection strategy, instead of relying on a single solution. An effective insider threat detection system combines several tools to not only monitor insider behavior, but also filter through the large number of alerts and eliminate false positives. Tools like Machine Learning (ML) applications can help analyze the data stream and prioritize the most relevant alerts. You can use digital forensics and analytics tools like User and Event Behavior Analytics (UEBA) to help detect, analyze, and alert the security team to any potential insider threats. User behavior analytics can establish a baseline for normal data access activity, while database activity monitoring can help identify policy violations.
