It's complete, rational, and doesn't require that you be a programmer to use it.Practical UNIX Security describes the issues, approaches, and methods for implementing security measures, spelling out what the varying approaches cost and require in the way of equipment. After presenting UNIX security basics and network security, this guide goes on to suggest how to keep intruders out, how to tell if they've gotten in, how to clean up after them, and even how to prosecute them. Filled with practical scripts, tricks, and warnings, Practical UNIX Security tells you what you need to know to make your UNIX system as secure as it possibly can be.Contents include:
- Understanding basic UNIX functions, such as users, passwords, groups, superuser, and the file system.
- Defending against security breaches.
- Defending against network and communication breaches, using modems, UUCP, NFS, secure NFS, Kerberos, and firewall machines.
