Essay on How Firewalls and Encryption Prevent Perpetrated Hacking Attacks
A network by characterization is more than one computer that are connected together electronically via a protocol so that computers can commune and share resources. This network develops the day-to-day life by adding value and expediency to the computers. Security would stipulate that not all users would be allowed access to extremely confidential information. There is other information that would be made obtainable to other users on a read only origin. Microsoft developed NT to be much protected. Most of this security is dedicated to protecting network resources as well as the filing system.
Figuring out the right amount of security for network takes some consideration. The first thing to consider is what your data is worth. A quick answer is, “Maybe more than you think.” When you consider the value of your data, remember risks such as legal liability and loss of competitive edge, or the effect of lost production if your network is compromised. Many analysts say very bluntly, “If you are on the Internet or have private network, you need a firewall” (Lakeland, 1997).
A firewall is a system that enforces an access control policy between two networks—such as your private LAN and the unsafe, public Internet. The firewall determines which inside services can be accessed from the outside, and vice versa. The actual means by which this is accomplished varies widely, but in principle, the firewall can be thought of as a pair of mechanisms: one to block traffic, and one to permit traffic. A firewall is more than the locked front door to your network —its security guard as well (Faulkner, 2001).
Firewalls are also important because they provide a single “choke point” where security and audits can be imposed. A firewall can provide a network administrator with data about what kinds and amount of traffic passed through it, how many attempts were made to break into it, and so on....
