CompTIA Security+ Exam Prep

Answer: B - A company wanting to put into place a system that is designed to seek security breaches would use an intrusion detection system (IDS). Intrusion detection is the process of detecting an unauthorized use of or attack upon a computer, network, or telecommunications infrastructure. IDS systems are designed to aid in mitigating the damage that can be caused by hacking or breaking into sensitive computer and network systems. The basic intent of the IDS tool is to spot something suspicious happening on the network and sound an alarm by flashing a message on a network manager’s screen, possibly sending a page, or even reconfiguring a firewall’s ACL setting.
