Clear DefinitionsAccess Control Audit
Think of an access control audit like a locksmith inspecting every door and key in a building to confirm that only the right people hold the right keys.
Access control audits verify that permission rules in blockchain systems are correctly configured and enforced.
Scope review: Assess all roles, permissions, and admin functions in contracts.
Misconfiguration detection: Identify overly broad or unintended access rights.
Compliance check: Ensure ACLs adhere to governance policies and regulations.
Continuous monitoring: Schedule periodic re‑audits as code or roles change.
Auditors extract on‑chain ACL data (e.g. OpenZeppelin AccessControl role mappings) via JSON‑RPC calls, then simulate transactions against role checks. They use symbolic execution and fuzzing to detect privilege escalation paths. Off‑chain, they inspect API gateways and admin dashboards for misaligned RBAC rules. Findings are mapped to CVSS scores and remediated with tightened modifiers and timelock enforcement.
Unaddressed ACL flaws can lead to unauthorized minting, fund drains, or governance attacks. Always remediate critical severity findings before mainnet deployment.
An audit only reflects the code and configuration at the time of review; subsequent updates or new integrations may introduce fresh risks.
