Privilege escalation can be defined as an attack that involves gaining illicit access of elevated rights, or privileges, beyond what is intended or entitled for a user. This attack can involve an external threat actor or an insider. Privilege escalation is a key stage of the cyberattack chain and typically involves the exploitation of a privilege escalation vulnerability, such as a system bug, misconfiguration, or inadequate access controls. In this blog, I will explain how privilege escalation works, the key attack vectors involved with privilege escalation, and the critical privileged access security controls you can implement to prevent or mitigate it.
