Picking just 10 Linux open source security tools isn’t easy, especially when network professionals and security experts have dozens if not several hundred tools available to them. . There are different sets of tools for just about every task—network tunneling, sniffing, scanning, mapping. And for every environment— Wi-Fi networks , Web applications, database servers. We consulted a group of experts (Vincent Danen, vice president of product security, RedHat; Casey Bisson, head of product growth, BluBracket; Andrew Schmitt, a member of the BluBracket Security Advisory Panel; and John Hammond, senior security researcher, Huntress) to develop this list of must-have Linux security tools. . Delve into crucial Linux utilities tailored for network specialists, addressing functionalities such as network probing, topology visualization, and encrypted communication tunnels..

Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source. .

This is a great security utility to be sure, but what about non-system files like those that constitute your Web site? Never fear: Tripwire, in partnership with Covalent, has recently released Tripwire for Web Pages into its security software stable. Tripwire for Web Pages works in much the same way as the flagship server product. After an initial scan of a Web site's pages, the server analyzes those pages before sending them to a browser. If a file has been modified without a Tripwire database update, customizable events are triggered, including delivering a "File not available" page to the visiting browser, rather than a page that may have been altered or defaced. This product has come along at just the right time, as hacktivist, black hat and script kiddie defacements increase, and corporate IT management staffs look to mitigate any embarrassment and downtime associated with a compromised Web server. Though site defacements can be accomplished by a security lapse as simple as an outdated FTP login, the resultant cleanup and downtime can be costly.
