• Security Controls: Implement protective measures such as firewalls, antivirus software, and intrusion detection systems.
• Continuous Monitoring: Regularly review and analyze security measures to adapt to new threats.

Practical Tip

• Regularly update your security posture by conducting audits and assessments to identify areas for improvement.

Step 2: Develop a Security Policy

• Purpose: A security policy outlines the rules and guidelines for maintaining security within an organization.

Key Elements

• Scope: Define what the policy covers, including employees, systems, and data.
• Roles and Responsibilities: Assign specific security responsibilities to individuals or teams.
• Acceptable Use Policy: Specify how employees can use organizational resources securely.
• Incident Response Plan: Outline procedures for responding to security breaches.

Common Pitfall to Avoid

• Neglecting to involve key stakeholders in the policy development process can lead to gaps in security coverage.
