Intrusion detection system (IDS)

-
 An intrusion detection system (IDS) An intrusion detection system (IDS) is a system that monitors network traffic for suspicious activity and alerts when such activity is discovered. While anomaly detection and reporting are the primary functions of an IDS, some intrusion detection systems are capable of taking action when malicious activity or anomalous traffic is detected, including blocking traffic sent from suspicious Internet Protocol (IP) addresses.

Computer cracker A computer cracker is an outdated term to describe someone who broke into computer systems, bypassed passwords or licenses in computer programs, or intentionally breached computer security. Computer crackers were motivated by malicious intent, for-profit, or just because the challenge was there. Cracker vs Hacker The antiquated phrase  computer   cracker  is not used anymore. It was originally proposed as an antonym, or the opposite, of the term  hacker . Hackers initially applied to only those who used their computing skills  without  malicious intent -- they broke into systems to identify or solve technical issues. Skillful technologists with altruistic motives were called  hackers ; those with bad intent were called  computer crackers . This distinction never gained much traction, however. In 1993, the Internet Users' Glossary defined a hacker as "a person who delights in having an intimate understanding of the intern...
