Firewalls are important components of any system for information security as they are the initial line of defense against attacks on security. This thesis explores the network security component through the use of firewalls and their features. All enterprises make use of firewalls as these systems function to provide enterprises with an adequate level of safety against attacks and damages. Firewalls are secure, however, it is possible to make them even more secure through using timely implementation and secure databases.
