Unformatted text preview: The main use of Biometric network security will be to replace 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 and while it may be expensive to set up at first, these devices save on administration and user assistance costs. Smart cards are usually a credit‐card‐sized digital electronic media. The card itself is designed to store encryption keys and other information used in authentication and other identification processes. The main idea behind smart cards is to provide undeniable proof of a user’s identity. Smart cards can be used for everything from logging in to the network to providing secure Web communications and secure e‐mail transactions. It may seem that smart cards are nothing more than a repository for storing passwords. Obviously, someone can easily steal a smart card from someone else. Fortunately, there are safety 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 PIN. There are other security issues of the smart card. The smart card is cost‐effective but not as secure as the biometric identification devices. 2. Software Developments The software aspect of network security is very vast. It includes firewalls, antivirus, vpn, intrusion detection, and much more. The research development of all security software is not feasible to study at this point. The goal is to obtain a view 1 1 of where the security software is heading based on emphasis being placed now. The improvement of the standard security software still remains the same. When new viruses emerge, the antivirus is updated to be able to guard against those threats. This process is the same for firewalls and intrusion detection systems. Many research papers that have been skimmed were based on analyzing attack patterns in order to create smarter security software. As the security hardware transitions to biometrics, the software also needs to be able to use the information appropriately. Current research is being performed on security software using neural networks. The objective of the research is to use neural networks for the facial recognition software. Many small and complex devices can be connected to the internet. Most of the current security algorithms are computational intensive and require substantial processing power. This power, however, is not available in small devices like sensors. Therefore, there is a need for designing light‐weight security algorithms. Research in this area is currently being performed...
