FOCUS on Linux: Security Tools

by Jonathan Day Sept. 1, 2017 via Symantec

Cyrus SASL is a library for providing an authentication mechanism for packages. It is used by IMAP, LDAP, ACAP and other standard protocols. Cryptix SASL is a SASL package for Java. It's very alpha in quality, at present, but does provide some basic authentication mechanisms. Libpcap is a fairly basic library for dumping all TCP packets on the network. It allows the application developer to write a simplistic TCP packet sniffer, to monitor for suspicious packets. Libpcap is not actively maintained, but is sufficiently well written that it is still widely used.
