How to prevent insider threats in cybersecurity

This article provides a high-level overview of insider threats, outlining their definitions, types (malicious, negligent, third-party), rising frequency and costs, and common warning indicators across access, performance, compliance, technical activity, and outside influences. It recommends preventive measures including least privilege, password policies, continuous security training, and the use of monitoring and control technologies (e.g., DLP, database monitoring, access controls, whitelisting, PAM, network flow analysis, SIEM), citing CISA guidance and advocating a Zero Trust approach.
