Task 5: Snort IDS mode can perform the following three actions: 1. Alert - Generate an alert using the selected alert method. 2. Log - Log the packet. 3. Pass - Ignore the packet. List the actions that can be preformed in Snort IPS mode.
Familiarize with the format of Snort rules Snort rules typically perform one of the five actions: o Alert – Generate an alert using the specified alert method and log the packet. o Log – log the packets only. o Pass – Ignore the packet. o Active – Signal an alert and turn on another dynamic rule. o Dynamic – remain idle until activated by an active rule and then switch to a log rule …

Rule Actions: There are five available default actions in Snort, alert, log, pass, activate, and dynamic. You can also define your own rule types and associate one or more output plugins with them.
Snort is the foremost Open Source Intrusion Prevention System (IPS) in the world. Snort IPS uses a series of rules that help define malicious network activity and uses those rules to find packets that match against them and generates alerts for users. Snort can be deployed inline to stop these packets, as well.
Snort has three primary uses: as a straight packet sniffer, a packet logger, or as a full-blown network intrusion detection system. It can perform protocol analysis, content searching/matching and can be used to detect a variety of attacks and probes.
Snort is an Intrusion Detection System designed to detect and alert on irregular activities within a network. Snort is integrated by sensors delivering information to the server according to rules instructions.
Snort is typically run in one of the following three modes:Packet sniffer: Snort reads IP packets and displays them on the console.Packet Logger: Snort logs IP packets.Intrusion Detection System: Snort uses rulesets to inspect IP packets.
Snort runs in three different modes: 1. Sniffer mode 2. Packet logger mode 3. Intrusion detection mode.
If a subscriber configures Snort to operate as a sniffer, it will scan network packets and identify them. Snort can also log those packets to a disk file. To use Snort as a packet sniffer, users set the host's network interface to promiscuous mode to monitor all network traffic on the local network interface.
Snort is a free and open source lightweight network intrusion detection and prevention system. Snort is the most widely-used NIDS (Network Intrusion and Detection System) that detects and prevent intrusions by searching protocol, content analysis, and various pre-processors.

SNORT is a powerful open-source intrusion detection system (IDS) and intrusion prevention system (IPS) that provides real-time network traffic analysis and data packet logging. SNORT uses a rule-based language that combines anomaly, protocol, and signature inspection methods to detect potentially malicious activity.
Suppression Lists allow control over the alerts generated by Snort rules. When an alert is suppressed, then Snort no longer logs an alert entry (or blocks the IP address if block offenders is enabled) when a particular rule fires.
These signatures are specifically designed to detect known exploits as they contain distinctive marks; such as ego strings, fixed offsets, debugging information, or any other unique marking that may or may not be related to actually exploiting a vulnerability.
There are five existing default job actions in Snort: alert, log, pass, activate, and dynamic are keyword use to define the action of rules. You can also go with additional options which include drop, reject, and sdrop.
Snort is a Network Intrusion Detection System (NIDS). It’s quite popular and is open source software which helps in monitor network traffic in real-time, hence it can also be considered as a packet sniffer. Basically, it examines each and every data packet in depth to see if there are any malicious payloads. it can also be used for protocol analysis and content searching. It is capable of detecting various attacks like port scans, buffer overflow, etc. It’s available for all platforms i.e. Windows, Linux, etc. It doesn’t require any recompilation with the system or hardware to added to your distribution; root privileges are required though. It inspects all the network traffic against the provided set of rules and then alerts the administration about any suspicious activity. it’s divided into multiple components and all the components work together to detect an intrusion. Following are the major components of snort :
Metadata is part of the optional rule which basically contains additional information of about snort rule that is written with the help of some keywords and with their argument details.
IDS Stands for Intrusion Detection System. The techniques and methods on which an IDS is founded on are used to monitor and reveal malicious activities both on the host and network level. Once the said activities occur then an alert is issued to aware every one of the attack. It can be hardware or software or a combination of both; depends on the requirement. An IDS use both signature or anomaly based technique together or separately; again depending on requirement. Your network topology determines where to add intrusion detection systems. Whether it should be positioned at one or more places depends on if you want to track internal threat or external threat. For instance, if you want to protect yourself from external traffic then you should place an IDS at the router and if you want to protect the inner network then place the IDS on every network segment.

HIDS stands for Host Intrusion Detection System which, obviously, acts as a host. Such types of IDS monitor system and application logs to detect intruder activity. Some IDS reacts when some malicious activity takes place, others monitor all the traffics coming to the host where IDS is installed and give alerts in real time.
