Cyber Hygiene


Overview#

Routine practices that keep systems and users resilient against common threats. Includes patching, backups, password hygiene, and regular security training.


Core objectives#

  • Establish shared definitions of Cyber Hygiene for security, engineering, and leadership teams.
  • Connect Cyber Hygiene activities to measurable risk reduction and resilience goals.
  • Provide onboarding notes so new team members can quickly understand how Cyber Hygiene works here.

Implementation notes#

  • Identify the primary owner for Cyber Hygiene, the data sources involved, and the systems affected.
  • Document the minimum viable process, tooling, and runbooks that keep Cyber Hygiene healthy.
  • Map Cyber Hygiene practices to standards such as ISO/IEC 27001, NIST CSF, or CIS Controls.

Operational signals#

  • Leading indicators: early warnings that Cyber Hygiene might degrade (e.g., backlog growth, noisy alerts, or missed SLAs).
  • Lagging indicators: realized impact that shows Cyber Hygiene failed or needs investment (e.g., incidents, audit findings).
  • Feedback loops: retrospectives and metrics reviews that tune Cyber Hygiene continuously.

  • Align Cyber Hygiene with defense-in-depth planning, threat modeling, and disaster recovery tests.
  • Communicate updates to stakeholders through concise briefs, dashboards, and internal FAQs.
  • Pair Cyber Hygiene improvements with tabletop exercises to validate expectations.
