Snort Blog: Snort Alpha 2 Available Now!

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..

To block abnormal behaviors and attacks within the network.1.2.3 Application-Based Intrusion Prevention Systems (AIPS)Application-Based Intrusion Prevention Systems (AIPS) focus on blocking attacks targeting specific applications, such as web applications and databases.2. Using Snort as a Host-Based Intrusion Detection SystemSnort is an open-source intrusion detection system that can analyze network traffic to detect abnormal behaviors and attacks within the network. Snort uses rules to identify suspicious traffic and takes appropriate actions based on the rules.2.1 Installing Snort for a Host-Based Intrusion Detection System“Ubuntu Host-Based Intrusion Detection System”sudo apt-get updatesudo apt-get install snortCentOSsudo yum install epel-releasesudo yum install snort2.2 Configuring Snort as a Host-Based Intrusion Detection SystemThe configuration file for Snort is located at /etc/snort/snort.conf. In this file, you can set Snort’s operating parameters and rules.Example: Configuring Snort’s Interface and Rulesinterface: eth0daq: pcap2.3 Starting Snortsudo systemctl start snort2.4 Viewing Snort LogsSnort’s log files are located at /var/log/snort/. You can review the logs to understand the suspicious traffic and attacks detected by Snort.Example: Viewing Snort Logssudo tail -f /var/log/snort/alert3. Using Suricata for Intrusion DetectionSuricata is an open-source intrusion detection and prevention system that can analyze network traffic to detect abnormal behaviors and attacks within the network. Suricata supports multiple protocols, including HTTP, TLS, and DNS.3.1 Installing Suricata“Ubuntu Host-Based Intrusion Detection System”sudo apt-get updatesudo apt-get install suricataCentOSsudo yum install epel-releasesudo yum install suricata3.2 Configuring SuricataThe configuration file for Suricata is located at /etc/suricata/suricata.yaml. In this file, you can set Suricata’s operating parameters and rules.Example: Configuring Suricata’s Interface and Rulesdefault-rule-path: /etc/suricata/rules3.3 Starting Suricatasudo systemctl start suricata3.4 Viewing Suricata LogsSuricata’s log files are located at /var/log/suricata/. You can review the logs to understand the suspicious traffic and attacks detected by Suricata.Example: Viewing Suricata Logssudo tail -f /var/log/suricata/fast.log4. Best Practices for Network Security Monitoring and Intrusion DetectionTo conduct effective network security monitoring and intrusion detection, it’s essential to follow some best practices:4.1 Regularly Update Rules and SignaturesRegularly update the intrusion detection system’s rules and signatures to keep the system up to date and capable of detecting the latest attacks.4.2 Set Reasonable Alert ThresholdsConfigure reasonable alert thresholds to reduce false positives and negatives, ensuring timely action when required.4.3.

MalmenatorNetwork Based Intelligent Malware DetectionSystem setup manualOn the raspberry pi install september 2019 release of raspbian OS. This was done following the guidance from tcpdump tools were setup on the Pi using sudo apt-get install -y tcpdumpSome dependencies were installed before installing snort by sudo apt install -y gcc libpcre3-dev zlib1g-dev libluajit-5.1-dev libpcap-dev openssl libssl-dev libnghttp2-dev libdumbnet-dev bison flex libdnetThen Snort IDS was installed following the snort official website bywget tar xvzf daq-2.0.6.tar.gz cd daq-2.0.6 sudo ./configure && make && sudo make install tar xvzf snort-2.9.9.0.tar.gz cd snort-2.9.9.0 sudo ./configure --enable-sourcefire && make && sudo make installSnort was configured to work with registered user rules as a NIDS which were obtained after getting the oinkcode on registration with the Snort website. The configuration was done using the following changes in the snort.conf file in /etc/snort/ directory.wget -O ~/registered.tar.gz sudo tar -xvf ~/registered.tar.gz -C /etc/snortsudo nano /etc/snort/snort.confMake sure that the configuration files have the rule specified correctly as follows# Path to your rules files (this can be a relative path)var RULE_PATH /etc/snort/rulesvar SO_RULE_PATH /etc/snort/so_rulesvar PREPROC_RULE_PATH /etc/snort/preproc_rules# Set the absolute path appropriatelyvar WHITE_LIST_PATH /etc/snort/rulesvar BLACK_LIST_PATH /etc/snort/rulesCheck if Snort is functioning by running Snort -V , the output should return as follows on the command line. Snort! ,,_ -*> Snort! Run snort by using the command sudo snort -dev -l /var/log/snort -A full -c /etc/snort/etc/snort.confTo run snort as a daemon in background we need to create a file for starting it up assudo nano /lib/systemd/system/snort.serviceAdd the following contents into this file[Unit]Description=Snort NIDS DaemonAfter=syslog.target
