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.
oversight - a mistake resulting from inattention. lapse. error, fault, mistake - a wrong action attributable to bad judgment or ignorance or inattention; he made a bad mistake; she was quick to point out my errors; I could understand his English in spite of his grammatical faults.
