What a Baseline Security Audit checks
The baseline review covers 50 controls across endpoints, identity, email, backup, network access, logging, and tool hygiene. It is a configuration review, and it changes nothing.
Last updated 21 October 2026
Endpoints and EDR
- An endpoint agent is deployed on the devices in scope
- Prevention is switched on, rather than left in a detect-only or audit mode
- Tamper protection is enabled
- The asset list and the protected-device list are compared for gaps
- Local administrator rights are reviewed
- Disk encryption is enabled on in-scope devices
- Removable-media handling is defined
- Unsupported operating systems are flagged
Identity and MFA
- MFA is required for users on the identity provider
- Privileged accounts use MFA, and break-glass accounts are not used day to day
- Legacy authentication is blocked
- A conditional access or equivalent sign-in policy exists
- Guest and external accounts are reviewed
- Stale accounts are disabled
- The number of global administrators is limited
- Password policy, including a banned-password list where the platform supports it
Email security
- SPF is published
- DKIM is signing outbound mail
- DMARC is in place, with a policy and reporting
- External sender marking is on
- Mailbox forwarding and inbox rules are reviewed
- Link and attachment protection is enabled
- Access to shared mailboxes is reviewed
Backup and recovery
- Endpoints and servers in scope are included in backup
- Mail and files in Microsoft 365, or the equivalent platform, are protected
- Identity configuration is backed up where the platform allows it
- An immutable or otherwise isolated copy exists
- A restore has been tested inside an agreed interval
- Backup administration is separated from day-to-day administration
Firewall and remote access
- Edge firewall configuration is reviewed
- Management ports exposed to the internet are identified
- Remote access (VPN or zero-trust access) and who can use it
- MFA on remote access
- Guest and corporate wireless are separated
- Site-to-site and vendor access is reviewed
- Firewall logging is enabled
- End-of-support network devices are flagged
Logging
- Sign-in logs are retained
- Endpoint alerts are retained
- Firewall or network logs are retained
- There is a named place where alerts are sent
- Time is synchronised across log sources
- Critical systems that do not log are listed as gaps
RMM and tool hygiene
- RMM roles, including who can run scripts, are reviewed
- MFA is required on the RMM and related admin portals
- A local administrator password solution, or an equivalent control, is in use
- Operating-system patch compliance is measured
- Third-party application patching is measured
- Security tools that are installed or billed but unused are identified
- Each security tool has a named owner
