/opt/so/saltstack/default/salt/firewall/assigned_hostgroups.map.yaml is where the default allow rules come together and pair hostgroups and portgroups and assign that pairing to a node based on its role in the grid. Port groups are a way of grouping together ports similar to a firewall port/service alias. If you have multiple entries for the same SID, it will cause an error in salt resulting in all of the nodes in your grid to error out when checking in. If you dont want to wait for these automatic processes, you can run them manually from the manager (replacing $SENSORNAME_$ROLE as necessary): Lets add a simple rule to /opt/so/saltstack/local/salt/idstools/local.rules thats really just a copy of the traditional id check returned root rule: Restart Suricata (replacing $SENSORNAME_$ROLE as necessary): If you built the rule correctly, then Suricata should be back up and running.

Some of these refer to areas where data is stored, while others point to configuration files that can be modified to change how Security Onion interacts with various tools. This writeup contains a listing of important Security Onion files and directories. This section will cover both network firewalls outside of Security Onion and the host-based firewall built into Security Onion. A tag already exists with the provided branch name. Security Onion is a platform that allows you to monitor your network for security alerts. Please note that Suricata 6 has a 64-character limitation on the IP field in a threshold. the rule is missing a little syntax, maybe try: alert icmp any any -> $HOME_NET any (msg:"ICMP Testing"; sid:1000001; rev:1;). Let's add a simple rule that will alert on the detection of a string in a tcp session. I went ahead and put in the below rules under /etc/nsm/local.rules and ran the rule-update command. Security Onion offers the following choices for rulesets to be used by Suricata. IPS Policy 'Re: [security-onion] Rule still triggering even after modifying to One of those regular interventions is to ensure that you are tuning properly and proactively attempting to reach an acceptable level of signal to noise. With this functionality we can suppress rules based on their signature, the source or destination address and even the IP or full CIDR network block. Security Onion Set Up Part 3: Configuration of Version 14.04 Check your syslog-ng configuration for the name of the local log source ("src" is used on SUSE systems). Open /etc/nsm/rules/local.rules using your favorite text editor. There may be entire categories of rules that you want to disable first and then look at the remaining enabled rules to see if there are individual rules that can be disabled. I have 3 simple use cases (1) Detect FTP Connection to our public server 129.x.x.x (2) Detect SSH Connection attempts (3) Detect NMAP scan. You may want to bump the SID into the 90,000,000 range and set the revision to 1. We offer both training and support for Security Onion. The National Institutes of Standards and Technology (NIST) 800-171 cybersecurity standard has four safeguards that are related to network traffic monitoring: 3.13.1: Monitor, control, and protect organizational communications (i.e., information transmitted or received by organizational information Pillars are a Saltstack concept, formatted typically in YAML, that can be used to parameterize states via templating.
