fail2ban - Daemon to ban hosts that cause multiple authentication errors

  •    Python

Fail2Ban scans log files like /var/log/auth.log and bans IP addresses having too many failed login attempts. It does this by updating system firewall rules to reject new connections from those IP addresses, for a configurable amount of time. Fail2Ban comes out-of-the-box ready to read many standard log files, such as those for sshd and Apache, and is easy to configure to read any log file you choose, for any error you choose. Though Fail2Ban is able to reduce the rate of incorrect authentications attempts, it cannot eliminate the risk that weak authentication presents. Configure services to use only two factor or public/private authentication mechanisms if you really want to protect services.

maltrail - Malicious traffic detection system

  •    Python

Maltrail is a malicious traffic detection system, utilizing publicly available (black)lists containing malicious and/or generally suspicious trails, along with static trails compiled from various AV reports and custom user defined lists, where trail can be anything from domain name (e.g. zvpprsensinaix.com for Banjori malware), URL (e.g. for known malicious executable), IP address (e.g. for known attacker) or HTTP User-Agent header value (e.g. sqlmap for automatic SQL injection and database takeover tool). Also, it uses (optional) advanced heuristic mechanisms that can help in discovery of unknown threats (e.g. new malware). Maltrail is based on the Traffic -> Sensor <-> Server <-> Client architecture. Sensor(s) is a standalone component running on the monitoring node (e.g. Linux platform connected passively to the SPAN/mirroring port or transparently inline on a Linux bridge) or at the standalone machine (e.g. Honeypot) where it "monitors" the passing Traffic for blacklisted items/trails (i.e. domain names, URLs and/or IPs). In case of a positive match, it sends the event details to the (central) Server where they are being stored inside the appropriate logging directory (i.e. LOG_DIR described in the Configuration section). If Sensor is being run on the same machine as Server (default configuration), logs are stored directly into the local logging directory. Otherwise, they are being sent via UDP messages to the remote server (i.e. LOG_SERVER described in the Configuration section).

pyHIDS - pyHIDS is a HIDS (host-based intrusion detection system) for verifying the integrity of a system

  •    Python

pyHIDS is a HIDS (host-based intrusion detection system) for verifying the integrity of a system. It uses an RSA signature to check the integrity of its database. Alerts are written in the logs of the system and can be sent via email to a list of users. You can define rules to specify files to be checked periodically. It is recommended to use Python >= 3.3.

py-idstools - idstools: Snort and Suricata Rule and Event Utilities in Python (Including a Rule Update Tool)

  •    Python

py-idstools is a collection of Python libraries for working with IDS systems (typically Snort and Suricata). See the idstools unified2 documentation for more information on read and parsing unified2 files.

expose - An Intrusion Detection System library loosely based on PHP IDS

  •    PHP

Expose is an Intrusion Detection System for PHP loosely based on the PHPIDS project (and using its ruleset for detecting potential threats). ALL CREDIT for the rule set for Expose goes to the PHPIDS project. Expose literally uses the same JSON configuration for its execution. I am not claiming any kind of ownership or authorship of these rules. Please see the PHPIDS github README for names of those who have contributed.

flightsim - A utility to generate malicious network traffic and evaluate controls

  •    Go

flightsim is a lightweight utility used to generate malicious network traffic and help security teams to evaluate security controls and network visibility. The tool performs tests to simulate DNS tunneling, DGA traffic, requests to known active C2 destinations, and other suspicious traffic patterns. The utility runs individual modules to generate malicious traffic. To perform all available tests, simply use flightsim run which will generate traffic using the first available non-loopback network interface. NB: when running the C2 modules, flightsim will gather current C2 addresses from the Cybercrime Tracker and AlphaSOC API, so requires egress Internet access.

nfr - A lightweight tool to score network traffic and flag anomalies

  •    Go

NFR is a lightweight application which processes network traffic using the AlphaSOC Analytics Engine. NFR can monitor log files on disk (e.g. Microsoft DNS debug logs, Bro IDS logs) or run as a network sniffer under Linux to score traffic. Upon processing the data, alerts are presented in JSON format for escalation. NFR expects to find its configuration file in /etc/nfr/config.yml. You can find an example config.yml file in the repository's root directory. The file defines the AlphaSOC Analytics Engine location and configuration, input preferences (e.g. log files to monitor), output preferences, and other variables. If you already have AlphaSOC API key, update the file with your key and place within the /etc/nfr/ directory.

fever - fast, extensible, versatile event router for Suricata's EVE-JSON format

  •    Go

The Fast, Extensible, Versatile Event Router (FEVER) is a tool for fast processing of events from Suricata's JSON EVE output. What is meant by 'processing' is defined by a number of modular components, for example facilitating fast ingestion into a database. Other processors implement collection, aggregation and forwarding of various metadata (e.g. aggregated and raw flows, passive DNS data, etc.) as well as performance metrics. It is meant to be used in front of (or as a replacement for) general-purpose log processors like Logstash to increase event throughput as observed on sensors that see a lot of traffic.
