Once you take the first couple months to get going on IDS, there are minimal hassles after that.

A major reason we looked at IDS was due to the volume of transactions and the interaction between sales, service and parts. It was a huge investment, and I was super proud when we first got it.

Overnight, it made a huge difference. It interlinked all of the departments together, and my accounting department was like night and day. Just having the right system in place can make you more successful. It's an excellent system to handle our motorhome business.

We find that IDS is very comprehensive and meets the needs of our full-service dealership: sales, parts, service, body shop and the business office.

Management Gain real-time visibility across your entire dealership to ensure complete control. The first of these analysis tools is the Zeek event engine.

Each event is logged, so this part of the system is policy-neutral — it just provides a list of events in which analysis may reveal repetition of actions or suspiciously diverse activity generated by the same user account. The mining of that event data is performed by policy scripts. An alert condition will provoke an action, so Zeek is an intrusion prevention system as well as a network traffic analyzer.

The policy scripts can be customized but they generally run along a standard framework that involves signature matching, anomaly detection, and connection analysis. Each policy is a set of rules and you are not limited to the number of active policies or the protocol stack additional layers that you can examine. At lower levels, you can watch out for DDoS syn flood attacks and detect port scanning. Sagan is a host-based intrusion detection system , so this is an alternative to OSSEC and it is also free to use.

Data sources from Zeek and Suricata can also feed into Sagan. Strictly speaking, Sagan is a log analysis tool. The element that it lacks to make it a stand-alone NIDS is a packet sniffer module. This tool would have to be a companion to other data gathering systems to create a full intrusion detection system. Some nice features of Sagan include an IP locator, which enables you to see the geographical location of the IP addresses that are detected as having suspicious activities.

This will enable you to aggregate the actions of IP addresses that seem to be working in concert to form an attack. Sagan can distribute its processing over several devices, lightening the load on the CPU of your key server. This system includes script execution, which means that it will generate alerts and perform actions on the detection of intrusion scenarios.

It can interact with firewall tables to implement IP bans in the event of suspicious activity from a specific source. So, this is an intrusion prevention system. The analysis module works with both signature and anomaly detection methodologies. Most of the IDS tools in this list are open source projects. That means that anyone can download the source code and change it. It will monitor your log and config files for suspicious activities and check on the checksums of those files for any unexpected changes.

Network analysis is conducted by a packet sniffer , which can display passing data on a screen and also write to a file. The analysis engine of Security Onion is where things get complicated because there are so many different tools with different operating procedures that you may well end up ignoring most of them. The interface of Kibana provides the dashboard for Security Onion and it does include some nice graphs and charts to ease status recognition.

Both signature-based and anomaly-based alert rules are included in this system. You get information on device status as well as traffic patterns.

All of this could really do with some action automation, which Security Onion lacks. If you have considered Tripwire, you would be better off looking at AIDE instead, because this is a free replacement for that handy tool. Tripwire has a free version, but a lot of the key functions that most people need from an IDS are only available with the paid-for Tripwire, so you get a lot more functionality for free with AIDE.

The system compiles a database of admin data from config files when it is first installed. That creates a baseline and then any changes to configurations can be rolled back whenever changes to system settings are detected. The tool includes both signature and anomaly monitoring methods. System checks are issued on demand and do not run continuously , which is a bit of a shortfall with this HIDS. As this is a command-line function, though, you can schedule it to run periodically with an operating method, such as cron.

If you want near real-time data, you could just schedule it to run very frequently. Maybe AIDE should be considered more as a configuration management tool rather than as an intrusion detection system. If you have heard about Aircrack-NG, then you might be a little cautious of this network-based IDS because it was developed by the same entrepreneur.

This free software is designed to defend wireless networks. However, at the moment, each installation can only include one sensor. The sensor is a packet sniffer, which also has the ability to manipulate wireless transmissions in mid-flow.

So the sensor acts as the transceiver for the system. The information gathered by the sensor is forwarded to the server, which is where the magic happens. The server program suite contains the analysis engine that will detect intrusion patterns. Intervention policies to block detected intrusions are also produced at the server.

The actions required to protect the network are sent as instructions to the sensor. The interface module of the system is a dashboard that displays events and alerts to the systems administrator.

This is also where settings can be tweaked and defensive actions can be adjusted or overridden. Samhain, produced by Samhain Design Labs in Germany, is a host-based intrusion detection system software that is free to use. It can be run on one single computer or many hosts, offering centralized data gathering on the events detected by the agents running on each machine. The tasks performed by each agent include file integrity checking, log file monitoring, and port monitoring.

The processes look for rootkit viruses, rogue SUIDs user access rights , and hidden processes. The system applies encryption to communications between agents and a central controller in multi-host implementations. Connections for the delivery of log file data include authentication requirements, which prevent intruders from hijacking or replacing the monitoring process.

The data gathered by Samhain enables analysis of activities on the network and will highlight warning signs of intrusion. However, it will not block intrusion or clear out rogue processes. You will need to keep backups of your configuration files and user identities to resolve the problems that the Samhain monitor reveals. One problem with hacker and virus intrusion is that the intruder will take steps to hide. This includes killing off monitoring processes. Samhain deploys a stealth technology to keep its processes hidden, thus preventing intruders from manipulating or killing the IDS.

Central log files and configuration backups are signed with a PGP key to prevent tampering by intruders.

Samhain is an open-source network intrusion detection system that can be downloaded for free. The central monitor will aggregate data from disparate operating systems. Fail2Ban is a free host-based intrusion detection system that focuses on detecting worrisome events recorded in log files, such as excessive failed login attempts.

The system sets blocks on IP addresses that display suspicious behavior. These bans usually only last a few minutes, but that can be enough to disrupt a standard automated brute force password cracking scenario. This security policy can also be effective against DoS attacks.

The actual length of the IP address ban can be adjusted by an administrator. Therefore, the system administrator has to be careful about access policies when setting up the software because a prevention strategy that is too tight could easily lock out bona fide users.

A problem with Fail2Ban is that it focuses on repeated actions from one address. Fail2Ban is written in Python and it is able to write to system tables to block out suspicious addresses.

These automatic lockouts occur in Netfilter, iptables, PF firewall rules, and the hosts. The attack monitoring scope of the system is defined by a series of filters that instruct the IPS on which services to monitor.

Each filter is combined with an action to perform in the event of an alert condition being detected. The hardware requirement of network-based IDS solution may put you off and push you towards a host-based system, which is a lot easier to get up and running. This is because you need to watch out for configuration changes and root access on your computers as well as looking at unusual activities in the traffic flows on your network.

The good news is that all of the systems on our list are free of charge or have free trials, so that you could try out a few of them. The user community aspect of these systems may draw you towards one in particular if you already have a colleague that has experience with it. The ability to get tips from other network administrators is a definitive draw to these systems. It makes them even more appealing than paid-for solutions with professional Help Desk support. If your company is in a sector that requires standard security compliance, such as a PCI, then you really are going to need an IDS solution in place.

Also, if you hold personal information on members of the public, your data protection procedures need to be up to scratch to prevent your company from being sued for data leakage. Hopefully, this guide has given you a push in the right direction. If you have any recommendations on your favorite IDS and if you have experience with any of the software mentioned in this guide, leave a note in the comments section below and share your thoughts with the community.

While an IDS works to detect unauthorized access to network and host resources, an IPS does all of that plus implements automated responses to lock the intruder out and protect systems from hijacking or data from theft. Host-based Intrusion Detection Systems HIDS examine log files to identify unauthorized access or inappropriate use of system resources and data. The main sources for host-based intrusion detection systems are logs generated by Syslog and Windows Events.

While some host-based intrusion detection systems expect the log files to be gathered and managed by a separate log server, others have their own log file consolidators built-in and also gather other information, such as network traffic packet captures.

Intrusion Detection Systems IDS only need to identify unauthorized access to a network or data in order to qualify for the title. The passive IDS can also store information on each detected intrusion and support analysis.

One is to compare events to a database of attack strategies, so the definition of normal use is any activity that does not trigger recognition of an attack. The other method is to use AI-based machine learning to record regular activity. The AI method can take a while to build up its definition of normal use. This is an amazing article. You really should keep this format up.
