The Analysis Console for Intrusion Databases (ACID) is a PHP-based analysis engine to search and process a database of incidents generated by security-related software such as IDSes and firewalls (e.g., Snort or ipchains). It provides a search interface for finding alerts matching practically any criteria. This includes arrival time, signature time, source/dest address/port, flags, payload, etc. ACID also provides the ability to annotate and logically group related events, delete false positives, or archive alerts among databases. Finally, a variety of statistics and graphs can be generated based on time, IP address, ports, alert classification, and sensor.
Advisory Check is a program that reads security advisories for you. It gathers security advisories using RSS, RDF, or XML feeds, compares them against the installed software, and alerts you if you're vulnerable. A wide variety of package managers can be queried to detect installed software. Remote systems can be monitored by using the integrated SSH, Windows-RPC, and Nmap support.
Airhook is a reliable data delivery protocol, like TCP. Unlike TCP, Airhook gracefully handles intermittent, unreliable, or delayed networks. Other features include session recovery, queue control, and delivery status notification. Airhook is useful for keeping connections running over bad wireless networks (like CDPD), intermittent dial-up connections, and any other network that doesn't work very well. The implementation includes a TCP proxy (so you can use HTTP, SSH, etc.) and a protocol library for applications that want more control (real-time media delivery, games, etc).
Akeni Web Chat is an IM system designed for universal accessibility and ease of deployment. With its browser-based client, there is no need to install any client side software. It is also firewall friendly and can be used whenever you have access to a Web browser. The rich client supports chat, notification, and conferencing. It also allows your staff to provide real time sales information and technical support to your customer using a simple Web-based interface.
AlarmMon is an alarm monitoring system for TCP/IP networks. It consists of an "alarm" client, an "alarmsvr" server, and several agents that work with a central registration database. It can track the status of verious services, including BIND, Sendmail, and modems, and send notifications by email, SMS, or pager.
AnomicFTPD is an RFC959-compliant FTP server with OS- independent user and group management. Active and passive modes, non-root mode, and anonymous and/or read-only modes are supported. A built-in client IP filter acts as a firewall and provides additional access limitation. The server has no online interface; attributes, groups, and user accounts are configured through text files. The protocol/ format-unspecified LIST command produces output that is compatible with most FTP clients, including common Web browsers in FTP mode.
Anteater is a log analyser for MTA logfiles (such as those produced by sendmail and postfix). The tool is written in 100% C++ and is very easy to customize. Input, output, and the analysis are modular class objects with a clear interface. Currently, there are modules for reading the syslog format of sendmail and postfix that do up to eight useful analyses and write the result in plain ASCII or HTML, to stdout or to files.
