Everything we have written on security & compliance.

Access control lists are a governance question, not a platform question. That reframing is the foundation of the single edition in this cluster - and it matters because most ServiceNow programmes treat ACLs as a technical configuration task delegated to a platform administrator, when they should be treated as a governance decision owned by a cross-functional accountability group.

The edition establishes an ownership model for access control that separates three concerns: who defines the policy (governance), who implements the policy (platform operations), and who validates the policy (audit and compliance). Most programmes collapse all three into the platform team, which means security decisions are made by the people with the least business context and the most pressure to ship quickly.

The quarterly review cadence is designed to catch drift - the gradual divergence between intended access policy and actual ACL configuration that accumulates silently between audit cycles. The review covers role composition, ACL rule accuracy, orphaned accounts and elevation patterns. It runs quarterly rather than annually because drift compounds: a single misconfigured ACL in Q1 can create a chain of dependent misconfigurations by Q4 that is far harder to unwind.

ServiceNow governance compliance is not a checkbox exercise. It is an ongoing operating discipline that requires clear ownership, regular cadence and the willingness to treat security findings as governance feedback rather than technical debt.
