To implement an Intrusion Detection System (IDS) on a Linux system, you can choose from many open-source or commercial tools. Here are the detailed steps to implement a Linux IDS using the open-source tools Snort and Suricata:Choose a Linux IDS ToolSnort: A Powerful Linux IDSSnort is a popular open-source network intrusion detection and prevention system (IDS/IPS).2. Suricata: A Linux IDSSuricata is another open-source network threat detection engine that provides powerful intrusion detection and prevention capabilities.Here are the steps to install and configure Snort and Suricata.Using Snort for Linux IDS1. Install Snort on Linux IDSFirst, ensure your system is updated:sudo yum update -yInstall dependencies:sudo yum install -y epel-releasesudo yum install -y gcc flex bison zlib libpcap pcre libdnet tcpdump libdnet-devel libpcap-devel pcre-develDownload and install DAQ:wget -xvzf daq-2.0.6.tar.gzcd daq-2.0.6./configure && make && sudo make installcd ..Download and install Snort:wget -xvzf snort-2.9.20.tar.gzcd snort-2.9.20./configure && make && sudo make installcd ..2. Configure Snort for Linux IDSCreate necessary directories:sudo mkdir /etc/snortsudo mkdir /etc/snort/rulessudo mkdir /var/log/snortsudo mkdir /usr/local/lib/snort_dynamicrulesCopy configuration files:sudo cp etc/*.conf* /etc/snort/sudo cp etc/*.map /etc/snort/sudo cp etc/*.dtd /etc/snort/Edit the main configuration file /etc/snort/snort.conf to configure it according to your network environment and needs.3. Download Rule Sets for Linux IDSDownload and extract the rule sets (registration required):wget -O snortrules.tar.gztar -xvzf snortrules.tar.gz -C /etc/snort/rules4. Run SnortRun Snort for testing:sudo snort -T -c /etc/snort/snort.confIf there are no errors, you can start Snort:sudo snort -A console -q -c /etc/snort/snort.conf -i eth0Using Suricata for IDS1. Install SuricataFirst, ensure your system is updated:sudo yum update -yInstall EPEL repository and dependencies:sudo yum install -y epel-releasesudo yum install -y suricata2. Configure SuricataSuricata’s configuration file is located at /etc/suricata/suricata.yaml. Edit this file according to your network environment and needs.3. Download Rule Sets for Linux IDSDownload the rule sets:wget -xvzf emerging.rules.tar.gz -C /etc/suricata/rules4. Run SuricataTest the configuration file:sudo suricata -T -c /etc/suricata/suricata.yaml -vStart Suricata:sudo suricata -c /etc/suricata/suricata.yaml -i eth0Centralized Log Management and MonitoringRegardless of which IDS tool you use, it is recommended to use centralized log management tools to collect and analyze log data. For example, you can use the ELK Stack (Elasticsearch, Logstash, Kibana) to centrally manage and visualize log data.1. Install Elasticsearchsudo yum install -y elasticsearchsudo systemctl enable elasticsearchsudo systemctl start elasticsearch2. Install Logstashsudo yum install -y logstashConfigure Logstash to collect Snort or Suricata logs.3. Install Kibanasudo yum install -y kibanasudo systemctl enable kibanasudo systemctl start kibanaConfigure Kibana to visualize data in Elasticsearch.SummaryBy installing and configuring Snort or Suricata, and combining them with centralized log management and monitoring tools, you can effectively implement intrusion detection to protect your systems and networks from potential threats. Regularly updating rule sets and monitoring log data is key to ensuring the effectiveness of your IDS.

Alert file in the logging directory. Snort has 6 alert modes. These are fast, full, console, cmg, unsock and none. We applied cmg and console modes. Also, the mode Snort is run in depends on which flags are used with the Snort command.Each alert carry the following information:IP address of the sourceIP address of the destinationPacket type and useful header informationSnort Rules StructureThe SNORT rule language determines which network traffic should be collected and what should happen when it detects malicious packets. Snort rules are divided into two logical sections, the rule header and the rule options. The rule header contains the rule's action, protocol, source, destination IP addresses, netmasks, the source and destination ports information. The rule option section contains alert messages and information on which parts of the packet should be inspected to determine if the rule action should be taken.

Packet, it can bypass Snort’s pattern matching. The attacked host’s TCP stack will reassemble these data and deliver it to the process listening on the target port, allowing the attack payload to evade Snort. The TCP stream plugin allows buffering and matching of TCP packets, enabling Snort to tackle such attacks.Using the spade (Statistical Packet Anomaly Detection Engine) plugin, Snort can report suspicious and abnormal packets, effectively detecting port scans.Snort also has strong system protection capabilities. Using the FlexResp feature, Snort can actively terminate malicious connections.4). Scalability, rapid response to new threatsAs a lightweight network intrusion detection system, Snort has enough extensibility. It uses a simple rule description language. The most basic rules contain just four fields: action, protocol, direction, and the port to monitor. For example:log tcp any any -> 10.1.1.0/24 79There are also functional options that can be combined to implement more complex features. There will be a separate article discussing how to write Snort rules. Users can obtain the rule sets from Additionally, renowned hacker Max Vision offers online technical support at supports plugins, allowing its functionalities to be extended with specific report and detection subsystem plugins. Currently supported plugins include database logging plugins, fragmented packet detection plugins, port scan detection plugins, HTTP URI normalization plugin, XML plugin, etc.Snort’s rule language is very simple, enabling quick reactions to new network attacks. Upon discovering a new attack, one can quickly find out the signature based on the Bugtraq mailing list and write detection rules. Due to its simple rule language, it is easy to learn, saving on personnel training costs.5). Adherence to GPLSnort follows the GPL, allowing any company, individual, or organization to freely use it as their NIDS.3. Installation3.1 How to obtain SnortSnort’s source code or RPM package can be obtained from the site Installing Snort from the source code requires the libpcap library, available for download from ftp://ftp.ee.lbl.gov.3.2 Installing Snort3.2.1 RPM package: Use the following command to install:bash#rpm -ihv –nodeps snort-1.7-1.i386.rpm3.2.2 Source code:Decompress the libpcap package:bash#uncompress libpcap.tar.Z bash#tar xvf libpcap.tarCompile the libpcap library:bash#./configure bash#makeDecompress snort-1.7.0.tar.gzbash#tar zxvf snort-1.7.0.tar.gzNavigate to the directory and compile Snort:bash# ./configure –with-libpcap-includes=/path/to/your/libcap/headers bash# make bash# make installThe configure script has additional options:–enable-smbalerts to compile SMB alerting code; –enable-flexresp to compile Flexible Response code; –with-mysql=DIR to support MySQL database; –with-postgresql=DIR to support PostSQL database; –with-odbc=DIR to support ODBC database; –enable-openssl to support SSL.

Snort Blog: GUIs for Snort

Snort GUI Package Update - 3.2.9.3 Release NotesThis update for the Snort GUI package implements support for the latest 2.9.9.0 version of the Snort binary. Release Notes for Snort 2.9.9.0 can be found here: some users are reporting a failure to start due to a probable syntax error in an Emerging Threats Exploit rule. This is not caused by a problem with the Snort update. It is an issue in the ET Open Exploit rules category. I suspect the ET guys will get it sorted out soon.Thanks to @pfcode for identifying the errant rule. Here is his post: Here is my post explaining how to interpret the error message in order to find the rule on your own: Each person seeing the error will probably have a different line number reported. This is because where the errant rule is located within the snort.rules file depends on how many rules you have enabled in your configuration. That snort.rules file contains all of your "enabled" rules. The path to the rules file contains your physical interface name along with a UUID number, so the path in your error message is going to be different. If you are impacted by the error, simply disable the rule using either the icons on the RULES tab or via the configuration on the SID MGMT tab. The SID of the rule is given in @pfcode's post (following the link given earlier).GUI Package New Features:NoneGUI Package Bug Fixes:When using the download buttons on the ALERTS, BLOCKED and SID MGT tabs, the downloaded files either have HTML appended to them (if downloading individual files) or when downloading a gzip archive it shows as corrupt on Windows.Redmine Bug #7555, translation data shown in breadcrumb link when no interfaces are defined for Snort and one of the interface settings tabs is selected.
