Emphasis: Security

Features

• Designing a Safe Network Using Firewalls by Paul Wouters
  It is by no means necessary to purchase specialized firewall hardware or even software. A Linux server--running on a $400 386 PC-- provides as much protection as most commercial firewalls, with much greater flexibility and easier configuration.
• Tripping Up Intruders with Tripwire by Kevin Fenzi
  You can ensure the security of your Linux machine with this program.
• TCFS: Transparent Cryptographic File System by Ermelindo Mauriello
  Think of TCFS as an extended NFS. It acts just like NFS, but allows a user to protect files using encryption.
• Wrap A Security Blanket Around Your Computer by Lee Brotzman
  TCP_wrappers: a simple, elegant and effective means to safeguard your network services.
