Mitigation

Mitigation (also “risk reduction” or “risk mitigation”) is the process of implementing security controls and measures to reduce the risk associated with vulnerabilities and threats, minimizing the potential impact of security incidents and improving the organization’s overall security posture. This process is fundamental in risk treatment and can include the implementation of technical controls such as security patches and encryption, organizational controls such as policies and procedures, or physical controls such as facility security, being essential for reducing the probability or impact of risks identified during risk assessment.

What is Mitigation?

Mitigation is a strategic process that:

  • Reduces risk associated with identified vulnerabilities
  • Implements appropriate security controls
  • Minimizes the impact of potential threats
  • Improves the overall security posture

Types of Mitigation

1. Technical Mitigation

  • Implementation of technical security controls
  • Configuration of protection systems
  • Development of secure applications
  • Implementation of security technologies

2. Administrative Mitigation

  • Development of policies and procedures
  • Implementation of administrative controls
  • Training and awareness of personnel
  • Risk management and compliance

3. Physical Mitigation

  • Physical access controls
  • Protection of critical infrastructure
  • Environmental security measures
  • Protection against natural disasters

Mitigation Strategies

1. Prevention

  • Implementation of preventive controls
  • Elimination of known vulnerabilities
  • Secure configuration of systems
  • Development of secure applications

2. Detection

  • Implementation of monitoring systems
  • Analysis of anomalous behavior

  • Execution of selected controls
  • Progress monitoring

5. Validation and Monitoring

  • Control effectiveness testing
  • Continuous monitoring of implementation
  • Risk reduction measurement
  • Control adjustment as needed
