As system and network
administrators, we play many roles. We are the ones who provide stable
and secure environments for electronic business in all of its forms,
from email to accounting systems to mission-critical Web applications.
However, despite our best efforts, disaster will occasionally strike.
In this series, I'll present what I feel are the 10 most important
steps a systems administrator can take to ensure that when that dreaded
3 a.m. page hits, you're prepared to react quickly, assess the
situation, and make everything right again. I call these the Ten
Commandments of system administration.
The 10 commandments:
- Thou shalt make regular and complete backups
- Thou shalt establish absolute trust in thy servers
- Thou shalt be the first to know when something goes down
- Thou shalt keep server logs on everything
- Thou shalt document complete and effective policies and procedures
- Thou shalt know what cable goes where
- Thou shalt use encryption for insecure services
- Thou shalt not lose system logs when a server dies
- Thou shalt know the openings into your servers
- Thou shalt not waste time doing repetitive and mundane tasks
