Security Planning

  • You need to determine, in broad terms, your security posture.
  • Consider the purpose of the machine. A public ftp server will generally have looser security than a firewall.
  • In broad terms, this posture will fall into one of two categories:
  • Everything not specifically denied is implicitly allowed.
  • Everything not specifically allowed is implicitly denied.
  • I prefer the latter option, as it is more secure.
