What Is an Insider ThreatAn insider threat is a security risk that originates from within the targeted organization. It typically involves a current or former employee or business associate who has access to sensitive information or privileged accounts within the network of an organization, and who misuses this access.

Traditional security measures tend to focus on external threats and are not always capable of identifying an internal threat emanating from inside the organization. Types of insider threats include:
Three types of risky behavior explained Malicious Insider Threat IndicatorsAnomalous activity at the network level could indicate an inside threat. Likewise, if an employee appears to be dissatisfied or holds a grudge, or if an employee starts to take on more tasks with excessive enthusiasm, this could be an indication of foul play. Trackable insider threat indicators include:
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.

What advantages do insider threats have over others?Insider threats such as employees or users with legitimate access to data are difficult to detect. These threats have the advantage of legitimate access, so they do not need to bypass firewalls, access policies, and cybersecurity infrastructure to gain access to data and steal it.
Why might insiders be able to cause damage to their organizations more easily than others?Why might "insiders" be able to cause damage to their organizations more easily than others? Insiders are given a level of trust and have authorized access to Government information systems.
What threat do insiders with authorized access to information or information systems pose quizlet?What threat do insiders with authorized access to information or information systems pose? They may wittingly or unwittingly use their authorized access to perform actions that result in the loss or degradation of resources or capabilities.
