How classic antivirus works
Classic antivirus compares files against a list of known threats. It works well against malware that has been seen before.
New or changed malware can slip past that list. Stolen passwords and fake emails also get around it.
Build layers of protection
Each layer covers a gap the others miss.
- Keep every device and app updated.
- Turn on two factor authentication for email and key accounts.
- Give staff only the access they need.
- Keep regular backups stored separately from your main systems.
Questions to ask today
If you answer no or not sure to any of these, it is time to review.
- Is security software up to date on every device?
- Does it watch for suspicious behaviour, not just known files?
- Would you know if it was switched off?
