In short, we call it IDS. It is a device or application that is used for keeping continues record of malicious activities or policy violations. This is a special security tool to protect the computer network systems from the harmful activities. There are three types of Intrusion Detection Systems. They are:
- Host based intrusion detection system.
- Network based intrusion detection system.
- Hybrid Intrusion detection system.
Overview of Snort:
Snort comes under the network based intrusion detection system (NIDS). Snort is an IDS device or application. It is open source and free application. It supports windows operating system as well as UNIX operating system. It can run also MacOS x and BSD. It was created by martin reosch in the year 1998. Snort uses both signature based intrusion detection and anomaly based intrusion detection. It can be configured with the signatures source emerging from threats or User created rules. It performs a lot of things such as protocol analysis, content searching and matching. There is a similar engine just like snort is suricata. Suricata is an open source network treat engine. Suricata is a direct competitor to snort. It employs signature based methodology rule and policy driven security anomaly. It is also capable of GUI multithreading and free. Suricata can protect your mails server that’s behind the firewall and whatever the services are behind the firewall when you have to open ports this gives you an insight into there. That is the main feature of the suricata.
Snort can be configured in three main things. They are sniffer, packet logger, and network intrusion detection. Sniffer looks at the header information. Packet logger logs the packet for later use. Network intrusion detection compares the packets against the rules. In the packet logger, when the snort runs in this mode, it collects each and every packet.
The program will monitor the traffic in the intrusion detection mode. We can also analyze that against the rule set defined by the user. It will then perform a specific task based on what has been identified. In the intrusion detection mode, we use the rules in snort.conf. The rules in the intrusion detection mode specify the suspicious activities. Snort sends an alert when a rule matches. We can get the alerts on the suspicious web traffic. And these alerts will save in log directory alerts. Administration, performance and log analysis are the third party tools for interfacing snort. Snort rules are flexible and easy to modify unlike many commercial network intrusions detection systems. Snort alerts some references to allow display of additional info about the alerts.
