    Deploy essential security controls such as firewalls, encryption, and identity management systems.

    Educate employees on cybersecurity best practices and their specific roles in maintaining security.

     Apply tailored security measures that fit the organization's size and sector, utilizing NIST's user friendly resources for practical guidance.

 5. Monitor and Detect Threats

     Team: IT Head, Security Operations Team

     Actions:

     Establish continuous monitoring systems to detect threats in real time.

     Utilize tools for threat detection and incident response, ensuring that they are regularly updated to combat evolving threats.

     Implement a feedback loop to refine detection capabilities continuously.

 6. Respond to Incidents

     Team: CISO, IT Head, Security Operations Team

     Actions:

     Develop a detailed incident response plan outlining steps for mitigating security breaches.

     Ensure roles and responsibilities are clearly defined and conduct regular drills to test response readiness.
