IPV4 Architecture: What Need To Developing A Secure Network Security
When developing a secure network, the following need to be considered:
1. Access – authorized users are provided the means to communicate to and from a particular network.
2. Confidentiality – Information in the network remains private
3. Authentication – Ensure the users of the network are who they say they are.
4. Integrity – Ensure the message has not been modified in transit.
5. Non repudiation – Ensure the user does not refute that he used the network.

Biometric systems and smart cards are the only new hardware technologies that are widely impacting security. Hardware device such as computer mice with built in thumbprint readers would be the next step up. These devices would be more expensive to implement on several computers, as each machine would require its own hardware device. The main use of Biometric network security will be replacing the current password system. Maintaining password security can be a major task for even a small organization. Passwords have to be changed every few months and people forget their password or lock themselves out of the system by incorrectly entering their password repeatedly. Very often people write their password down and keep it near their computer. This is of course completely undermines any effort at network security. Biometrics can replace this security identification method. The use of biometric identification stops this problem features built into smart cards to prevent someone from using a stolen card. Smart cards require anyone who is using them to enter a personal identification number (PIN) before they’ll be granted any level of access into the system. The PIN is similar to the PIN used by ATM machines. When a user inserts the smart card into the card reader, the smart card prompts the user for a PIN. This PIN was assigned to the user by the administrator at the time the administrator issued the card to the user. Because the PIN is short and purely numeric, the user should have no trouble remembering it and therefore would be unlikely to write the PIN down. But the interesting thing is what happens when the user inputs the PIN. The PIN is verified from inside the smart card. Because the PIN is never transmitted across the network, there’s absolutely no danger of it being intercepted. The main benefit, though, is that the PIN is useless without the smart card, and the smart card is useless without the
