SecTools.Org: Top 125 Network Security Tools For more than a decade, the Nmap Project has been cataloguing the network security community's favorite tools. In 2011 this site became much more dynamic, offering ratings, reviews, searching, sorting, and a new tool suggestion form . This site allows open source and commercial tools on any platform, except those tools that we maintain (such as the Nmap Security Scanner , Ncat network connector , and Nping packet manipulator ). We're very impressed by the collective smarts of the security community and we highly recommend reading the whole list and investigating any tools you are unfamiliar with. Network Security Tools

SSH OpenSSH is a FREE version of the SSH connectivity tools that technical users of the Internet rely on. Users of telnet, rlogin, and ftp may not realize that their password is transmitted across the Internet unencrypted, but it is. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. The encryption that OpenSSH provides has been strong enough to earn the trust of Trend Micro and other providers of cloud computing.Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions.
