Insecure services are:
- Outdated software or systems
- Services that send data without encryption (in plain text)
These are easy targets for hackers. All systems must stay updated to remain secure.
Unnecessary functions are:
- Features or services your network doesn't need
- Systems that serve no business purpose
Remove these immediately. Unnecessary functions often go unmonitored, become outdated, and create security risks.
Why does this matter?
- Document all services you must keep, even if they're currently insecure
- Update these services regularly to make them secure
- Remove all unnecessary functions
- Monitor and update all necessary functions consistently
The goal: Keep only what you need, and keep it secure.
