An important system administration task, and a principle of running a defensible network, is keeping operating systems and applications up-to-date. Running current software is critical when older services are vulnerable to exploitation. Obtaining new features not found in older applications is another reason to run current software. Fortunately, open source software offers a variety of means to give users a secure, capable computing environment.
This talk presents multiple ways to keep the FreeBSD operating system up-to-date. I take a FreeBSD 5.2.1 RELEASE system through a subset of security advisories to explain the different sorts of patches an administrator might apply. Time-permitting, ways to keep FreeBSD applications up-to-date will be
presented as well.
