A penetration test or pen test is a simulated cyber-attack against computer systems, application systems, and IT infrastructure to discover loopholes. These simulated cyber-attacks come in diverse forms with the intent of breaching a system through its servers, web or mobile applications, and other endpoints. The purpose of pen testing is to discover exploitable vulnerabilities in a controlled setting before cybercriminals take advantage of them.

Contrary to popular beliefs, an insider threat is not always a security risk within an organization's immediate perimeter. Current employees and managers aside, an insider threat could be a former employee who had access to specific information, a third-party consultant, or a business partner.

The era of individual threat actors has been replaced by organized syndicates utilizing sophisticated processes to break through expansive networks and IT architecture.

When an organization has a highly remote workforce or shifts its operations to remote working, even temporarily, they could be opening their network to many risks. One way to mitigate them is by implementing UEBA software. UEBA stands for User and Event Behavior Analytics or User and Entity Behavior Analytics, depending on who you ask.
