Introduction to Mitigation Techniques

Introduction to Mitigation Techniques
Focus: Core concepts, categories, and practical steps for reducing risk in information security, project management, and environmental contexts.

1. What Is Mitigation?

Key Idea: Mitigation ≠ elimination. It aims to manage risk to an acceptable level when total removal is impractical or too costly.

2. Mitigation‑Lifecycle Framework

1. Identify – Recognize potential threats, hazards, or risks.
2. Assess – Evaluate likelihood and potential impact (quantitative or qualitative).
3. Prioritize – Rank based on risk‑score or business impact.
4. Select Controls – Choose appropriate mitigation techniques.
5. Implement – Deploy controls, assign responsibilities, allocate resources.
6. Monitor & Review – Track effectiveness, adjust as conditions change.

(The loop repeats continuously; mitigation is an ongoing activity.)

3. Major Categories of Mitigation Techniques

4. Common Mitigation Techniques (Examples)

4.1. Defense‑in‑Depth (Layered Security)

• Goal: Multiple, independent controls so that failure of one does not expose the asset.
• Layers: Perimeter → Network → Host → Application → Data → User.
• Typical controls: Firewalls → IDS/IPS → Host‑based antivirus → Secure coding → Encryption → MFA.

4.2. Least Privilege & Role‑Based Access Control (RBAC)

• Goal: Users receive only the permissions needed for their role.
• Implementation steps:
  1. Define roles and required permissions.
  2. Map users to roles.
  3. Enforce via directory services (Active Directory, LDAP).
  4. Review periodically (e.g., quarterly).

4.3. Patch Management

• Goal: Close known software vulnerabilities before they can be exploited.
• Process:
  1. Inventory assets.
