UnixReview continues its overview of the Sair Exams, with a list of the top 50 things you need to know to pass Sair Exam 104. Here are the first three:

1. The Computer Emergency Response Team (CERT) and Coordination Center (CC) should be one of the first places to turn to when an attack is suspected. Information about CERT/CC can be found at: http://www.cert.org.

2. Systems administrators must always strive to minimize the vulnerability of their system(s) to risks. This can be aided by keeping backups of all data, verifying software before installing it, keeping installed software current, and closely monitoring activity logs.

3. PGP (Pretty Good Privacy) can be used to encrypt data and keep it secure when sending across a medium. Two files to be cognizant of are secring.pgp (the private key), and pubring.pgp (the public key). PGP uses 128-bit encryption, and more information on it can be found at: http://www.pgp.com. In addition to PGP, you can also use DES and the crypt command for encryption.
