An intrusion detection system (IDS) inspects all inbound and outbound network activity and identifies suspicious patterns that may indicate a network or system attack from someone attempting to break into or compromise a system. There are several ways to categorize an IDS:
Civil inattention. Civil inattention is the process whereby strangers who are in close proximity demonstrate that they are aware of one another, without imposing on each other â a recognition of the claims of others to a public space, and of their own personal boundaries.
inÂ·ciÂ·denÂ·tal. adj. 1. Occurring or likely to occur as an unpredictable or minor consequence: the principle that even annoying, intrusive, and offensive speech is to be protected by the courts and tolerated by the public as incidental to an open society (Frederick Schauer).
