A toxic combination of access is a set of permissions that should not be held together because they create excessive fraud, abuse, or control-bypass risk. It matters because risk often comes from combinations of privileges, not just a single permission alone.
What is a Toxic Combination of Access?
Some access pairings give one person or system too much end-to-end control, such as the ability to create vendors and approve payments, or request access and approve it. Identifying these combinations is a core part of strong access governance.
What Toxic Combinations Commonly Involve
Common issues include segregation-of-duties conflicts, admin plus audit rights, development plus production approval powers, and identity roles that allow self-approval or hidden privilege escalation.
Toxic Combination vs. Single Excessive Permission
A single excessive permission can be risky. A toxic combination focuses on conflicting access held together that creates a more dangerous control failure.
Frequently Asked Questions
Why do toxic combinations matter?
Because they enable abuse, mistakes, or concealment that normal oversight assumes cannot happen in one pair of hands.
How do teams control them?
By defining conflict rules, reviewing high-risk entitlements, and enforcing segregation of duties in approval and operational workflows.
