Looking for a network detection software? Snort Free Download is now available. This is one of the best network IDS and IPS software.
On this page, we are going to talk about the free and open source software named Snort. Snort is a network Intrusion Prevention System (IPS) and Intrusion Detection System (IDS) which was created by “Martin Roesch” in 1998 who is the CTO and former founder of the Sourcefire. Snort is now owned and developed by Cisco, which also purchased the Sourcefire in the year of 2013, at which Martin is the Chief of Security Architect (CSA).
In the year 2009, snort was entered in InfoWorld’s Open Source Hall of Fame and came as one of the best open-source software of all of time.
What is Snort (The Network Intrusion Detection System)?
Snort is a totally open-source network intrusion detection and prevention system. This is the software that is working at the backend or at your firewall and looks for every traffic and activity which might indicate the firewall has failed to set the second line of defense and keeps out intruders. It might be looking for the traffic that generates for activity by malware or is generated after a breach of the firewall, or by the activities performed by the malware or other software.
It also can be used as the sniffer, streaming the data to your screen, watching the network packets, or as a logger, it does the same but writes the information to the disk, it also runs in the Network Intrusion Detection System (NIDS) mode. It also watches the network in this mode instead of simply displaying or recording it in this mode. Snort compares the rules and the traffic against a set of instructions and then it takes action then those rules are specified when it finds a match. These rules combine the benefits of protocol, signature and anomaly-based inspection.

This is the most important part of a snort NIDS setup with a set of many rules available on the snort.org for download which will cover all of the typical usage scenarios. If those standard rules do not fit the needs, then there is plenty of documentation available within the software from where you can easily get help regarding the software or its tools and functions. The manual of the Snort in the PDF form is 200 pages long at least, but it consists of all of the information which is required regarding the snort software.
Snort’s open-source IDS and IPS have the ability to perform packet logging on internet protocols (IP) networks, real-time traffic analysis. Snort also performs content searching and matching, protocol analysis and etc.
This particular program can also be used to detect attacks or probes which include the operating system fingerprinting attempts, butter overflows, stealth port scans, server message block probes, and semantic URL attacks.
Different Modes of Snort
Snort can also be configured or constructed in 3 different main modes which are as follows: Sniffer mode, Network Intrusion Detection mode, and Packet Logger mode.
- Sniffer Mode: In this mode of snort the program will read it in the form of network packets and displays them on the console.
- Packet Logger Mode: In this mode of snort the program will chart the packets to the disk.
- Intrusion Detection Mode: In this mode of snort the program will monitor the network traffic and analyze all of it against the rule defined by the user. Then the specific actions are performed by the program based on what has been identified.
