Sample text

Such lists also tend to suggest that system management has some kind of coherence across the vastly different environments in which people find themselves responsible for computers. There are similarities, of course, but what is important on one system won't necessarily be important on another system at another site or on the same system at a different time. Similarly, systems that are very different may have similar system management needs, while nearly identical systems in different environments might have very different needs.

For small, standalone systems, there is often no distinction between the user and the system administrator. And even if your workstation is part of a larger network with a designated administrator, in practice, many system management tasks for your workstation will be left to you. Users of Unix systems who are not full-time system managers but who perform administrative tasks periodically. This book assumes that you are familiar with Unix user commands: that you know how to change the current directory, get directory listings, search files for strings, edit files, use I/O redirection and pipes, set environment variables, and so on.

The chapter also covers the more advanced security configuration available by using access control lists (ACLs) and role-based access control (RBAC). It also discusses the process of hardening Unix systems. In reality, though, security is something that is integral to every aspect of system administration, and a good administrator consciously considers the security implications of every action and decision. Thus, expecting to be able to isolate and abstract security into a separate chapter is unrealistic, and so you will find discussion of security-related issues and topics in every chapter of the book.
