The uncomfortable truth about most security breaches is that they did not require a genius attacker — they exploited an ordinary, avoidable mistake. The good news is that fixing these mistakes is usually inexpensive and dramatically reduces your risk. Here are the five we see most often.
1. Treating security as a one-time project
Buying a firewall once and considering security "done" is a common and costly error. Threats evolve constantly; security is an ongoing process of monitoring, patching, and review. Fix: treat it as a continuous program — the model behind managed security.
2. No multi-factor authentication
Passwords get stolen, guessed, and reused. Without MFA, a single stolen password is a breach. Fix: enable MFA everywhere — it is one of the highest-impact, lowest-cost controls available.
3. Inconsistent patching
Known vulnerabilities with available patches are a leading cause of breaches. "We’ll update it later" is how systems stay exposed for months. Fix: a scheduled patching routine, not ad-hoc updates.
4. Untested backups
Many businesses have backups but have never tried to restore them — and discover during a crisis that they do not work. Fix: verified backups with regular test restores, your last line of defense against ransomware.
5. Ignoring the human factor
Technology cannot fully protect against an employee who clicks a convincing phishing email. Fix: regular, practical security awareness training so staff become a defense rather than a vulnerability.
