Continuously watch for threats and have a plan to respond to incidents.

Analogy: Keeping Watch

Even with locks and cameras, you remain vigilant for unusual activity around your home and know who to call if something goes wrong.

Real-Life Example:

A business might use a Security Information and Event Management (SIEM) system to detect unauthorized access and have an incident response team ready to act.

9. Test and Improve: Stay Resilient

What It Means:

Regularly test your defenses and update your strategy based on new threats.

Analogy: Fire Drills at School

Practicing fire drills ensures everyone knows what to do in an emergency. Similarly, testing your security plan ensures it works when needed.

Real-Life Example:

Conducting a penetration test reveals weaknesses in an organization’s defenses, prompting updates to policies and technologies.

10. Ensure Compliance: Meet Regulatory Requirements

What It Means:

Follow legal and industry standards to avoid penalties and build trust.

Analogy: Following Building Codes

You ensure your home is built to code to avoid fines and ensure safety. Similarly, organizations must follow standards like GDPR, HIPAA, or PCI-DSS.

Real-Life Example:

A financial institution encrypts all customer data to comply with GDPR and avoid hefty fines.
