Regular maintenance is crucial for sustaining a robust cybersecurity posture. This quarterly checklist includes essential tasks that should be performed every three months to ensure your defenses remain effective and up-to-date.

System and Software Updates:

Update Operating Systems: Ensure all devices are running the latest versions of their operating systems with all security patches applied.

Update Applications: Check and update all critical applications, especially security software, to the latest versions.

Review and Update Mobile Devices: Ensure that all company-used mobile devices are updated and secure.

Passwords and Access Controls:

Change Critical Passwords: Rotate passwords for sensitive accounts, including admin and any system-level users.

Review User Access Rights: Audit and update user permissions to ensure employees have appropriate access levels, and revoke unnecessary privileges.

Multi-Factor Authentication Check: Ensure MFA is enabled for all critical accounts and systems.

Backup and Recovery:

Verify Backup Systems: Check that all critical data is being backed up regularly and backups are complete and uncorrupted.

Test Data Recovery: Perform a test recovery of data from backups to ensure the process is working correctly and efficiently.

Review and Update Disaster Recovery Plans: Ensure your disaster recovery plan is up-to-date and reflects any changes in your business or IT infrastructure.

Security Policies and Training:

Schedule Security Training: Plan and schedule the next security awareness training for employees, focusing on recent threats and reminders of best practices.

Network and Hardware:

Inspect Network Security Measures: Review firewalls, intrusion detection systems, and other network security appliances for optimal configuration and functionality.

Audit Hardware Inventory: Confirm that all hardware is accounted for, properly secured, and that any unused or obsolete equipment is safely decommissioned.

Environmental Checks: Ensure that physical security measures, such as access controls to server rooms or hardware storage, are intact and functional.

Incident Response and Monitoring:
