Quarterly IT security review checklist and runbook
A quarterly IT security review checklist gives IT teams a repeatable way to inspect core controls, capture evidence, assign remediation, and report risk. This guide focuses on the practical checks: identity, MFA, privileged access, patching, endpoint protection, backups, Microsoft 365, firewall, DNS, logging, vulnerabilities, and incident readiness.

Why it matters
Use the checklist to make security reviews repeatable
A security review is only useful if the same critical areas are checked consistently and findings are tracked to closure. A repeatable checklist helps IT teams avoid missing common control gaps while still allowing deeper investigation where risk is higher.
This version of the quarterly review is designed as a working runbook. It helps teams collect the right evidence, ask the right technical questions, and leave the review with clear action items rather than a vague status report.
Practical rule: For each security control, capture evidence, identify exceptions, assign an owner, set a due date, and verify closure before the next quarter.
Review scope
Checklist domains for quarterly review
Identity controls
Check MFA, conditional access, privileged roles, inactive users, guests, service accounts, and emergency access.
Endpoint controls
Review patching, EDR/antivirus, encryption, local admin rights, unsupported devices, and device inventory.
Recovery controls
Verify backup success, restore testing, retention, ransomware recovery, offsite/immutable copies, and DR dependencies.
Microsoft 365 controls
Review email security, admin access, sharing, OneDrive/SharePoint, Teams, audit logging, and security alerts.
Network controls
Inspect firewall rules, VPN, remote access, Wi-Fi, DNS, certificates, switch/firewall updates, and logging.
Governance controls
Track findings, exceptions, risk decisions, remediation owners, due dates, budget needs, and retest evidence.
Review matrix
Quarterly review checklist matrix
| Area | What to verify | Questions to answer | Evidence |
|---|---|---|---|
| Identity check | MFA, privileged roles, inactive accounts, guests, or break-glass controls are incomplete. | Export evidence, validate exceptions, assign remediation, and verify risky accounts first. | Which identity gap creates the highest business risk? |
| Endpoint check | Devices are missing patches, protection, encryption, or inventory accuracy. | Prioritize internet-facing, executive, privileged, unsupported, and high-value endpoints. | Which devices could disrupt operations if compromised? |
| Backup check | Backups run but restore testing or ransomware recovery evidence is weak. | Test restores, confirm retention, verify protected systems, and update recovery assumptions. | What proof shows recovery will work? |
| Network check | Firewall, VPN, DNS, Wi-Fi, or remote access settings are stale or undocumented. | Review rules, owners, logs, exposed services, and change history. | Which exposed path needs review this quarter? |
| Finding follow-up | A prior issue remains open or is repeatedly deferred. | Escalate owner, budget, blocker, compensating control, or formal risk acceptance. | What decision is required to stop deferring it? |
Step-by-step review
Quarterly security checklist runbook
1
Prepare the evidence pack
Collect exports, reports, screenshots, logs, tickets, and prior-quarter action status before the review meeting.
2
Review highest-risk controls first
Start with identity, privileged access, backup recovery, endpoint protection, exposed services, and critical vulnerabilities.
3
Document exceptions
Record exception owner, business justification, compensating control, expiration date, and review cadence.
4
Assign remediation
Create action items with owner, due date, priority, evidence needed, and expected business impact.
5
Validate completed work
Require retest evidence, screenshots, logs, or configuration exports before closing significant findings.
6
Carry forward open risk
Report unresolved findings, blockers, funding needs, and accepted risks to leadership before the next quarter.
Common risks
Common checklist mistakes
Checking without evidence
A verbal confirmation is not enough for important controls; capture proof.
Same findings every quarter
Repeated findings need escalation, funding, compensating control, or risk acceptance.
Ignoring exceptions
Exceptions should have owners, expiration dates, and compensating controls.
No retest
Security fixes should be validated before a finding is closed.
No executive summary
Leadership needs the top risks, decisions needed, and business impact, not only technical details.
No owner
Each finding needs one accountable owner, even when multiple teams contribute.

FAQ
Quarterly IT security checklist FAQ
Why use a quarterly security checklist?
It helps teams review critical controls consistently and track remediation before small gaps become larger risks.
What evidence should be saved?
Save reports, exports, screenshots, logs, tickets, restore test results, access review evidence, and remediation validation.
Should the checklist replace a security audit?
No. It supports ongoing operations, but formal audits and assessments may require deeper independent testing and validation.
How should findings be prioritized?
Prioritize by exploitability, business impact, exposure, recovery impact, compliance need, and age of the finding.
Can IT Perfection help with the checklist?
Yes. IT Perfection can help collect operational evidence, remediate IT findings, and coordinate deeper security review when needed.
