Security Handbook: The essential guide to establishing a security policy

There exist many threats to hinder the normal running of organisations, including, of course, being hit by a computer virus intrusion or hack.

In order to mitigate the risks of being hit, you need to monitor a whole host of things including system patches, intrusion detection, analyse sensitive material leaving the organisation and intelligence on firewall activity.

There are absolutely vital business reasons for doing so; being hit by a virus or worm or some other threat has a direct business-related effect, not some esoteric technological one.
