zmaildrop is a mail delivery agent (MDA) specifically designed to analyze emails, extract relevant information, and send it to a Zabbix server. It is designed for use with schedulers, backup tools, and security monitoring tools that report information via email. As an MDA, it integrates easily with mail transfer agents (MTA) such as Postfix, Exim, and Qmail, or mail retrieving tools as Fetchmail. It is highly configurable, using a simple YAML syntax to describe tool-specific mail formats.
ssh-forcecommand is a script to safely execute remote commands via ssh. It is especially aimed at automated remote commands (in which ssh keys are not secured via password), where a compromise of the remote system could also compromise the local system. To prevent this, ssh-forcecommand can be invoked through the ssh configuration, which will limit the remote system so that it can only execute a set of statically defined commands. This way, compromising the local system is made much more difficult.
lpkfuse is a FUSE filesystem that lets you place all the SSH public keys of your users into LDAP. Without this tool, you would have to patch your SSH server (for example using openssh-lpk) to support this. But with lpkfuse, you just need to amend AuthorizedKeysFile in your sshd_config file. Other benefits include LDAP resilence and caching/local-fallback in case no LDAP servers are accessible.
WormTrack is a network IDS that allows detection of scanning worms on a LAN by monitoring anomalous ARP traffic. This allows detection of scanning threats on the network without having privileged access on a switch to set up a dedicated monitor port. It does not require constant updating of the rules engine to address new threats.
Network Inventory Lookup Assistant (NILA) is a combination network inventory database and lookup tool. It is designed to be compact and easily extensible to provide a custom solution for your network. The backend is a Perl CGI script which processes requests and returns output. It uses a SQL server for its storage and retrieval. The frontend is a Perl script which queries the HTTP backend and returns results. It is intended to be simple enough that you can take full advantage of its querying and updating abilities from a console or shell script.
