PostgreSQL is a robust relational database system with over 25 years of active development that runs on all major operating systems. It is fully ACID compliant, and has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). It includes most SQL92 and SQL99 data types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. It also supports storage of binary large objects, including pictures, sounds, or video. It has native programming interfaces for C/C++, Java, .Net, Perl, Python, Ruby, Tcl, and ODBC, among others, and exceptional documentation.
Lynis is an auditing and hardening tool for Unix derivatives like Linux/BSD/Solaris. It scans systems to detect software and security issues. Besides security-related information, it will also scan for general system information, installed packages, and possible configuration mistakes. The software is aimed at assisting automated auditing, software patch management, and vulnerability and malware scanning of Unix-based systems.
Berkeley DB (libdb) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications. It includes b+tree, queue, extended linear hashing, fixed, and variable-length record access methods, transactions, locking, logging, shared memory caching, database recovery, and replication for highly available systems. DB supports C, C++, C#, Java, PHP, and Perl APIs. It supports key-value pair (NoSQL), SQL, and Java Object formatted data. It is available for a wide variety of Unix platforms as well as QNX, Android, Mac OS X, and several varieties of Windows.
Splunk is an engine for machine data. Use Splunk to collect, index, and harness the fast moving machine data generated by all your applications, servers, and devices: physical, virtual, and in the cloud. Search and analyze all your real-time and historical data from one place. Splunking your machine data lets you troubleshoot problems and investigate security incidents in minutes, not hours or days. Monitor your end-to-end infrastructure to avoid service degradation or outages. Meet compliance mandates at lower cost. Correlate and analyze complex events spanning multiple systems. Gain new levels of operational visibility and intelligence for IT and the business.
389 Directory Server (formerly Fedora Directory Server) is a full-featured LDAPv3 compliant server. In addition to the standard LDAPv3 operations, it supports multi-master replication, fully online configuration and administration, chaining, virtual attributes, access control directives in the data, Virtual List View, server-side sorting, SASL, TLS/SSL, and many other features. The transactional Berkeley DB 4.2 is used as its data store and a full plug-in API allows developers to extend the the functionality of the server in many ways, and many of the core features of the server are already implemented using this API. The server is very mature, having started out as Netscape Directory Server.
nxlog is a modular, multi-threaded, high-performance log management solution with multi-platform support. In concept, it is similar to syslog-ng or rsyslog, but is not limited to Unix/syslog only. It can collect logs from files in various formats, receive logs from the network remotely over UDP, TCP, or TLS/SSL on all supported platforms. It supports platform-specific sources such as the Windows Eventlog, Linux kernel logs, Android device logs, local syslog, etc. Writing and reading logs to/from databases is also supported for many database servers. The collected logs can be stored into files, databases, or forwarded to a remote log server using various protocols. The old BSD Syslog and the newer IETF syslog standard (RFC 3164 and RFC 5424-5426) are fully supported by nxlog in addition to XML, JSON, CSV, GELF, and other custom formats. A key concept in nxlog is to be able to handle and preserve structured logs so there is no need to convert everything to syslog and then parse these logs again at the other side. It has powerful message filtering, log rewrite, and conversion capabilities. Using a lightweight, modular, and multi-threaded architecture which can scale, nxlog can process hundreds of thousands of events per second.
Bastille Unix (formerly Bastille Linux) aims to be the most comprehensive, flexible, and educational Security Hardening Program for Red Hat (Fedora Core, Enterprise Linux, and original Red Hat), SuSE, Gentoo, Mandrake, and Debian Linux, as well as HP-UX and Mac OS X. Virtually every task it performs is optional, providing immense flexibility. It educates the installing admin regarding the topic at hand before asking any question. The interactive nature allows the program to be more thorough when securing, while the educational component produces an admin who is less likely to compromise the increased security.
Arkeia Network Backup is designed for organizations that require fast, easy-to-use, and affordable data protection. It backs up critical data to disk, tape, and cloud storage. Arkeia protects all major virtual platforms including VMware, Hyper-V, XenServer, and more than 200 physical platforms including Windows, Mac OS X, Linux, Netware, most UNIX flavors, and BSDs. The company’s source-side Progressive Deduplication technology helps users realize better performance at a lower cost by reducing data volumes. Arkeia’s deduplication is crucial to accelerating replication of on-premise backups to private or public clouds.
FusionInventory Agent is an generic inventory agent that can collect information from various sources including the local machine, network, and remote devices. It also has the ability to send Wake on LAN requests and deploy software. The agent can be used with GLPI, Uranos, Rudder, Pulse2, and OCS Inventory.
Cfengine is a tool for setting up and maintaining BSD and System-5-like operating system optionally attached to a TCP/IP network. You can think of cfengine as a very high level language, much higher level than Perl or shell: a single statement can result in many hundreds of operations being performed on multiple hosts. Cfengine is good at performing a lot of common system administration tasks, and allows you to build on its strengths with your own scripts.
