What Is a Security Audit and Should You Do a Personal One?
What Is a Security Audit?
A security audit is a systematic review of security measures to assess their effectiveness, identify weaknesses, and find areas for improvement. In organizations, security audits are formal evaluations of systems, practices, and controls. But the concept applies powerfully to individuals too: a personal security audit is a periodic checkup of your own accounts, passwords, devices, and privacy, helping you find and fix security gaps before they become problems. Just as you might periodically review your finances or health, periodically auditing your security is a valuable practice.
This guide explains security audits and how to perform a personal one.
The Value of a Personal Security Audit
Periodically auditing your own security is valuable because:
Security drifts over time: Over time, accounts accumulate, passwords age, settings change, and gaps develop. A periodic audit catches these.
Finding gaps before attackers do: An audit identifies weaknesses — reused passwords, missing 2FA, exposed information — so you can fix them before they are exploited.
Maintaining good security: Regular audits maintain your security over time, rather than letting it degrade.
Peace of mind: Knowing you have reviewed and strengthened your security provides confidence.
A personal security audit, done periodically (e.g., a few times a year), keeps your security strong.
Performing a Personal Security Audit
A personal security audit reviews the key areas of your digital security:
1. Audit Your Passwords
- Check for reused passwords (a major vulnerability) — use your password manager's tools, which often identify reused passwords
- Check for weak passwords and strengthen them
- Ensure important accounts have strong, unique passwords
- Check Have I Been Pwned to see if any of your credentials have been breached, and change any breached passwords
- If you do not use a password manager, this is the time to adopt one
2. Audit Your Two-Factor Authentication
- Check which accounts have 2FA enabled
- Enable 2FA on important accounts that lack it (especially email, financial, and other critical accounts)
- Consider upgrading to stronger 2FA (authenticator apps or hardware keys/passkeys) where you use SMS
- Ensure you have backup codes or recovery methods for your 2FA
3. Audit Your Accounts
- Review your accounts, identifying old or unused ones
- Close or delete accounts you no longer use, reducing your exposure
- Check important accounts' recent activity and active sessions for anything unfamiliar
- Review third-party apps with access to your accounts, revoking unnecessary ones
4. Audit Your Email Security
- Ensure your primary email (the key to your other accounts) has strong security — a strong unique password and strong 2FA
- Check your email's forwarding and filter rules for anything you did not set
- Review your email's recovery options
5. Audit Your Devices
- Ensure your devices have current security updates
- Check that devices have strong locks and encryption enabled
- Ensure Find My Device / remote wipe is enabled
- Review device security settings
6. Audit Your Privacy
- Review privacy settings on your important accounts and social media
- Check what information about you is exposed, and reduce it where possible
- Consider using Temp90 going forward for non-essential registrations to reduce your email exposure
- Review app permissions on your devices
7. Audit Your Backups
- Ensure important data is backed up (following the 3-2-1 approach)
- Test that your backups work and can be restored
- Verify you have an isolated backup (protecting against ransomware)
Acting on Your Audit
A security audit is valuable only if you act on what it finds:
Fix the gaps: Address the weaknesses your audit identifies — strengthen passwords, enable 2FA, close unused accounts, update devices, and improve privacy and backups.
Prioritize: Prioritize the most important fixes (e.g., securing your email, fixing reused passwords on important accounts, enabling 2FA where missing).
Make it a habit: Perform a personal security audit periodically (a few times a year) to maintain your security over time.
Making Security Audits Manageable
To make personal audits manageable:
Use tools: Your password manager's tools (identifying reused, weak, and breached passwords) make the password audit much easier. Have I Been Pwned checks for breaches.
Do it incrementally: If a full audit feels overwhelming, address areas incrementally — passwords one time, 2FA another, and so on.
Focus on impact: Prioritize the highest-impact items (email security, password manager adoption, 2FA on important accounts), which provide the most protection.
Frequently Asked Questions
What is a personal security audit?
A personal security audit is a periodic checkup of your own digital security — reviewing your passwords, two-factor authentication, accounts, email security, devices, privacy, and backups to find and fix gaps before they become problems. Just as you might periodically review your finances or health, auditing your security (a few times a year) catches weaknesses that develop over time — like reused passwords, missing 2FA, or unused accounts — so you can address them and maintain strong security.
How often should I do a personal security audit?
A few times a year is a reasonable cadence for a personal security audit, keeping your security strong as accounts accumulate, passwords age, and settings change over time. You can also do focused checks when prompted — for example, checking for breached passwords after a major breach is announced, or reviewing an account's security after suspicious activity. The key is making it a periodic habit rather than a one-time event, so your security is maintained over time.
What are the highest-priority items in a personal security audit?
The highest-impact items are securing your primary email (the key to your other accounts) with a strong password and strong 2FA, fixing reused passwords (adopting a password manager if you have not), and enabling 2FA on important accounts that lack it. Also valuable are checking for breached credentials (via Have I Been Pwned), closing unused accounts, ensuring your devices are updated and secured, and verifying your backups work. Prioritizing these provides the most protection.
Conclusion
A security audit is a systematic review of security to assess its effectiveness and find weaknesses, and the concept applies powerfully to individuals: a personal security audit is a periodic checkup of your accounts, passwords, devices, and privacy that helps you find and fix gaps before they become problems. Because security drifts over time — accounts accumulate, passwords age, and settings change — a periodic audit (a few times a year) maintains your security. A personal audit reviews your passwords (checking for reused, weak, and breached ones), two-factor authentication (enabling and strengthening it), accounts (closing unused ones, reviewing access), email security (securing the key to your other accounts), devices (updates, locks, encryption), privacy (settings and exposure), and backups (existence and testing). The value comes from acting on what you find — fixing gaps, prioritizing the highest-impact items like email security and reused passwords, and making the audit a habit. Using tools like your password manager and Have I Been Pwned makes it manageable. By periodically auditing and strengthening your own security, you catch and fix weaknesses before attackers can exploit them, maintaining strong protection across your digital life over time.
