As technology managers, maintaining security within your systems is one of the many hats you wear. Two important concepts to understand are trust boundaries and privilege escalation. Let's explore what these mean and how they can affect your organization.
What are Trust Boundaries?
In any network or system, a trust boundary separates areas where different security policies are enforced. Imagine two sections: one that’s highly secure and another less so. The point where they meet is the trust boundary. For example, your local network space and the open internet have a trust boundary. Understanding trust boundaries helps you define where your security checks should start or end.
Why Do Trust Boundaries Matter?
Trust boundaries are crucial because they determine where you place your security controls. If trust boundaries are ignored, sensitive data could leak or unauthorized access could occur. For example, if users on a public network enter a part of your system that requires strict authentication without strong checks, you risk unapproved access to confidential data.
What is Privilege Escalation?
Privilege escalation happens when someone gains more access rights than they should. Think of a regular user suddenly getting admin permissions—they can then access more parts of the system than intended, potentially causing harm. Privilege escalation can be achieved by exploiting vulnerabilities or even user errors.
