Network Security Issues
anon.Metho
Methodology Editor
There are tons of reasons why networks have problems with security but there are some major reasons:
- Many potential attack points
How many times have you been told that the only secure computer is totally disconnected? Itīs true. A network has tons of points where it can be attacked. Firewalls and other control mechanisms help with this problem but itīs still much less secure than even a single connected computer.
- Network and System Complexity
Security on a network which combines many pieces of software, many operating systems, many passwords and many users is very difficult. Keeping track of the latest vulnerabilities, password and port auditing, firewall maintenance, and the like is very difficult. It becomes even more difficult if the network wasnīt designed with security in mind.
- Unknown Size & Perimeter
A network is almost infinitely expandable. One network may be expanded a node or two, two networks may be combined, et cetera. Expandability is an advantage in every part of a network except security because of the presence of new and untrusted hosts and clients.
- Anonymity and Unaccountability
Attacks can be mounted from next door or across the world. The user can only be tracked by entry point, IP, et cetera. Computer to computer authentication just isnīt good enough, and accountability simply isnīt there.
- Sharing
Windows sharing is just the beginning. Tons of users have access to networks, making them less and less secure with each user.
- Unpredictable Routing
Because a message may go from A to B to C to D to E, or A, D, C, B, E thereīs no totally reliable way to track a message -- or a security threat. |
