What is the difference between an IDS (Intrusion Detection System) and a vulnerability scanner?
If you were comparing securing a network to securing a home, an Intrusion Detection System would be the burglar alarm. An IDS is triggered when someone attempts to enter your network. A vulnerability scanner, on the other hand, is like the home security consultant. Its role is to proactively examine the home, or network, looking for vulnerabilities including various entry points, the integrity of the firewalls and IDS systems and so on.
