firewall protection

Before you understand the many Firewall Protections, you should know firewall’s limitations first.

Here they are:

  • not guarantee data integrity
  • not support authenticity of the source of data
  • no control over how the packets were created
  • not support confidentiality- no encryption among different firewalls unless it is incorporated with VPN features
  • don’t protect against some Internet threats like virus attack and/or password cracking
  • Do not provide protection from insider threats i.e. Insider Attacks
  • can’t protect against traffic that doesn’t go through it (example: dial-up modems in the private network can be a backdoor)
  • Once pass through it, it can do nothing!
  • Single point of failure

Definitely there are more, can you think of some more?
