SSHGuard protects hosts from brute-force attacks against SSH and other services. It aggregates system logs and blocks repeat offenders using several firewall backends, including iptables, ipfw, and pf.

This is dhcpd-pools ISC dhcp shared network and pool range usage analysis. Purpose of command is to count usage ratio of each IP range and shared network pool which ISC dhcpd is in control of. Users of the command are most likely ISPs and other organizations that have large IP space. Program is written C. Design goal is to get analysis done quickly where there is lots of data. On cheap laptop the speed of analysis is roughly 100k leases per second. Number of ranges, or shared networks, does not make any significant difference in getting analysis done.

Highly available with I/O handlers to store data for disaster recovery. Granular management of data parsing and routing. Filtering and enrichment to optimize security and minimize cost. The lightweight, asynchronous design optimizes resource usage: CPU, memory, disk I/O, network. No more OOM errors! Integration with all your technology, cloud-native services, containers, streaming processors, and data backends. Fully event-driven design leverages the operating system API for performance and reliability. All operations to collect and deliver data are asynchronous.

Free-SA is logs processor and report generating tool. It can be used to control traffic usage, to evaluate conformance to the Internet access security policies, to investigate security incidents, to evaluate web server efficiency and to detect troubles with server configuration.

this tool tries to repair your broken pcap and pcapng files by fixing the global header respectively packet blocks and recovering the packets by searching und guessing the packet headers or blocks

Sgrep (sorted grep) is a much faster alternative to traditional Unix grep when searching large files, because sgrep searches sorted input files using a fast binary search to find matching lines.

FW1-Loggrabber is a command-line tool to grab logfiles from Checkpoint FW-1 remotely using Checkpoints LEA (Log Export Api), which is one part of Checkpoints OPSEC API.

Logpp is a tool for preprocessing event logs and feeding relevant data to other programs for storing or in-depth analysis. Logpp reads lines appended to input files, matches the lines with patterns, and writes the results to given destinations.

IPCAD runs captures traffic on the specified interfaces (BPF, PCAP, divert, tee, ULOG, IPQ), and records the traffic for later retrieval and analysis. Traffic exported via RSH or NetFlow.

Comprehensive & high performance data distribution &transformation system. Features a simple, user-friendly event driven scripting interface transparently generates & execs highly efficient Perl/C code. Uses:ETL,datawarehousing,statistics,data-cleansing.

Caudium WebServer is a single process multi-threaded webserver. It has a built-in pre-processing language and includes an easy to use web-based configuration interface.

DBD2 inserts database records from TCP input. It is a companion project to Syslgod2 and an application in its own right. It ships with a backgrounding client for generic use. The client sends whatever information the user puts on the command-line to the back-end daemon via TCP. Upon successful transmission, the client exits. On failure, it backs off and retries until its life-time timer expires. The back-end daemon accepts data from Syslogd2 or its own client and inserts that data (and envelope information) into one or more databases using MySql client library or dbi drivers (also on SourceForge). The client needs no configuration (all input is via command-line). It is intended for hosts to make database entries without needing database client or interface code. Syslogd2 integration allows DBD2 to act as Syslogd2's database back-end for MySql and other databases supported by the dbi drivers. Original purpose was to track Linux cluster job status but other uses exist.

GoAccess is a real-time Apache web log analyzer and interactive viewer that runs in a terminal and provides fast and valuable HTTP statistics for system administrators that require a visual report on the fly.

A tool to visualize interactively huge amounts of eventdata. Uses an innovative hierarchical zoomlens scaling from quarters down to 50 ms.

The Big Brother Log Analyzer (BBLA) is a package consisting of an HTTP logger and of a log analyzer. It provides a lightweight and free solution (with no banners!) for individual users and/or systems administrators willing to track their audience.

Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attacker's IP into IPFW table effectively blocking them. Addresses are removed from the table after expiration period

An extended version of GNU tail, with features targeted primarily (though not exclusively) at bandwidth and latency analysis of Financial Information eXchange (FIX) protocol log files.

SRG is a log file analyser and report generator for the Squid web proxy. It is fast and was created to allow easy integration with other authentication systems. SRG is flexible and can report right down the the level of individual files requested.

ATTENTION: Snare Lite is unsupported legacy software. While it will remain a part of the SourceForge community, it is no longer secure and compliant. For up to date Snare software check out Snare Enterprise. https://www.snaresolutions.com/try-snare-for-free/ Snare Enterprise was created to keep up with the fast paced security software market. It started with the desire to create premium logging and SIEM tools that were agnostic by nature so they could be used to boost any SIEM architecture regardless of third party developers. In fact, the agnostic nature allows it to bridge gaps between multiple SIEM implementations across business units. For more on use cases, check out the Intersect Alliance website. https://www.snaresolutions.com/ Snare Enterprise’s premium features include: - Regulatory Compliance - TLS Encryption - Log Simulcasting - TCP – Guaranteed Log Delivery - USB Device Monitoring - And more!

A web server log file analyzer that combines extreme speed with high flexibility and scalability.Can produce XHTML output for viewing with a web browser. Supports standard CLF and combined (Apache), as well as W3C (IIS) logs format.

This project is an attempt to redesign the snort database schema and to provide a new analysis frontend and associated tools.

deStats is a rather small, fast, and cool IRC Logfile stats generation program. It will eventually become an open source alternative to the existing ones such as mIRCStats, and IRCStats.
