CORE EXPERTISE |
- Intrusion detection: In lots of ways, intrusion detection is just packet sniffing combined with logging, with a layer of automated intelligence thrown on top of it all. An intrusion detection system or IDS has a set of rules that, combined with knowledge of what's going on across a network, can provide monitoring and response to potentially problematic situations on your network.
- Packet logging: Snort can not only monitor packets in real time, but also log those packets. Logging lets you manually, or automatically, deal with those packets, and to have some record of what's happened. Whether you're weeding through old packets searching for an intrusion, or Snort is sounding a software alert based on something it just logged, packet logging takes you from a real-time tool to a tool that can persist the data it reacts to in various forms.
- Packet sniffing: Snort can monitor packets, both incoming and outgoing, directed at the machine it's installed on. It also can monitor packets on the network it's running on, and quite a bit more. This is probably Snort's most basic function, and everything else it does depends on this ability to detect and observe network traffic in a packet form.
