Golden rule 16

 Maintain Clear Change Management

Meaning:
Document, review, and control all changes to systems, configurations, networks, and applications to prevent unexpected issues and ensure smooth operations.

Why it matters:

1. Reduces downtime: Proper planning avoids service interruptions.

2. Minimizes errors: Reviewing changes helps catch mistakes before they affect users.

3. Ensures accountability: Tracks who made changes and why.

4. Supports troubleshooting: Documentation makes it easier to trace problems back to specific changes.

5. Complies with policies: Many organizations and regulations require documented change management.

Best Practices:

• Require approval for critical changes before implementation.

• Maintain a change log with details, dates, and responsible personnel.

• Test significant changes in a staging environment first.

• Communicate planned changes to affected users or teams.

• Review and update change management processes regularly.

Golden Rule 15

 Follow the Principle of Least Privilege

Meaning:
Give users, applications, and services only the minimum access rights necessary to perform their tasks. Avoid granting unnecessary permissions.

Why it matters:

1. Improves security: Reduces the risk of accidental or malicious misuse.

2. Limits damage: If an account is compromised, the potential impact is minimized.

3. Enhances compliance: Many regulations require strict access controls.

4. Reduces human error: Users can’t accidentally modify or delete critical systems or data.

Best Practices:

• Review permissions regularly and remove unnecessary access.

• Apply role-based access control (RBAC) where possible.

• Avoid giving admin/root privileges unless absolutely required.

• Use temporary elevated privileges only when needed.

• Audit and log access to sensitive systems for accountability.

  PoLP in the Context of ITIL

  While ITIL (Information Technology Infrastructure Library) doesn't explicitly define the Principle of Least Privilege, it emphasizes the importance of security and access control within its processes.

  Relevant ITIL Processes:

  • Change Management: Ensures that changes to IT services are made with minimal risk and disruption. Implementing PoLP can prevent unauthorized changes and reduce potential security vulnerabilities.

  • Access Management: Focuses on granting authorized users the right to use a service while preventing access to unauthorized users. PoLP is integral to this process, ensuring users have only the access necessary for their roles.

  • Information Security Management: Aims to protect the confidentiality, integrity, and availability of information. Adhering to PoLP helps in safeguarding sensitive data and systems.

  
  
  

GoldeN Rules- 14

 Monitor Systems Continuously

• Meaning:
  Keep a constant eye on servers, networks, applications, and critical systems to detect performance issues, errors, or security threats before they impact users or business operations.

  Why it matters:

  1. Early problem detection: Catch issues before they escalate into outages or data loss.

  2. Improves reliability: Ensures systems run smoothly and efficiently.

  3. Enhances security: Detect suspicious activity or breaches in real time.

  4. Optimizes performance: Helps identify bottlenecks or underused resources.

  5. Supports planning: Provides data for capacity planning and infrastructure improvements.

  Best Practices:

  • Use monitoring tools like Nagios, Zabbix, PRTG, or built-in cloud monitoring.

  • Set up alerts for critical thresholds (CPU, memory, disk usage, network traffic).

  • Track logs and events regularly for anomalies.

  • Analyze historical trends to anticipate future issues.

  • Review and adjust monitoring configurations as systems evolve.
