Intrusion detection systems

feature

full-time monitoring tools placed at the most vulnerable points or “hot spots” of

corporate networks to detect and deter intruders continually. The system gen-

erates an alarm if it finds a suspicious or anomalous event. Scanning software

looks for patterns indicative of known methods of computer attacks, such as

bad passwords, checks to see if important files have been removed or modified,

and sends warnings of vandalism or system administration errors. Monitoring

software examines events as they are happening to discover security attacks in

progress. The intrusion detection tool can also be customized to shut down a

particularly sensitive part of a network if it receives unauthorized traffic.

Defensive technology plans for both individuals and businesses must include

antivirus protection for every computer.
