Are interactive login banners worth having?
The general consensus is that they are, but what should the banner say?
Some things that are being considered (no particular order):
- ownership of the equipment
- no expectation of privacy
- Monitoring may be done
- authorized use only
- don't use words like "Welcome"
- in the local language if possible
- length of the banner: short and terse, long and wordy
- don't identify the use of the equipment
- vague or specific
