One of the first things to understand when comparing probabilistic and deterministic approaches to identity security is how each operates. This is especially true in environments that rely on user and behavior analytics (UEBA). A UEBA environment will much more commonly rely on probabilistic methods, as the name implies.
Let's break these approaches down and explore how they can work together.
Identity, Credential, and Access Management, commonly referred to as ICAM, marks a fundamental evolution from the traditional approaches to access control in organizations.
What do traditional access controls look like? In simple terms, it was straightforward: usernames and passwords. Physical access secured through ID cards or PINs; system and resource access granted through basic logins. Most of this managed manually by IT or security staff. And unless someone forgot their password or hit a forced password reset deadline, accounts and permissions were rarely reviewed or updated!
It's astonishing! Such methods were once (and in some cases, still are) the norm!
But organizations today face far more complex challenges. Let's take a closer look.
