• Easy to forget to update after changes
• Outdated documentation is misleading
• Maintenance burden is ongoing

Documentation vs. Action:

• Focus on documentation may delay action
• Can become excuse for not taking action
• Balance documentation with implementation
• Documentation should support, not replace action
• Avoid documentation overload

Documentation Trade-offs

Comprehensive vs. Concise:

• Comprehensive documentation is thorough but lengthy
• Concise documentation is quick to read but may lack detail
• Balance based on audience and purpose
• Executive summaries vs. technical details
• Different detail levels for different audiences

Standardized vs. Flexible:

• Standardized templates ensure consistency but may be rigid
• Flexible approach allows customization but lacks consistency
• Use templates with flexibility for specific cases
• Balance structure with adaptability
• Templates provide foundation, customize as needed

Detailed vs. Actionable:

• Detailed documentation provides context but may be verbose
• Actionable documentation is concise but may lack background
• Balance detail with actionability
• Provide enough context for understanding
• Focus on what reader needs to know and do

FAQ

What’s the difference between a vulnerability report and an incident report?

Vulnerability reports document security weaknesses found during assessments. Incident reports document actual security incidents that occurred. Vulnerabilities are potential issues; incidents are actual events.

How detailed should security documentation be?

Documentation should be detailed enough for the intended audience. Technical teams need technical details; executives need business impact summaries. Balance completeness with readability.

How often should security documentation be updated?

Documentation should be updated whenever relevant information changes. Policies typically reviewed annually; procedures updated as processes change; incident reports completed immediately after incidents.

Who should write security documentation?

Security team members typically write security documentation, but subject matter experts should contribute. Technical writers can help with clarity and structure. Management should review executive summaries.

What tools should I use for security documentation?

Use documentation platforms (Confluence, Notion), version control (Git), and templates. Choose tools that are accessible, searchable, and support collaboration.

How do I make documentation actionable?

Provide specific, step-by-step instructions. Include examples, code snippets, and configurations. Set clear priorities and timelines. Include validation and testing steps.
