1.0INTRODUCTION
1.1 Background to the Study
Firewalls are main(prenominal) tools in data and ready reckoner system protection. A firewall is a computer system that sits among a protected net area and the rest of the net income and attempts to stop malicious traffic from entering the protected network, time allowing legitimate traffic to pass in or out. In other words, firewalls are an effective gage mechanism for protect a local anaesthetic computer system or network of systems from network- found security threats and vulnerabilities while at the same time bread and butter gate to the outside world.
Embedded Firewall System (EFW) is a impertinently introduced firewall system that has a solution for one of the most important limitations of firewalls, preventing insider attacks. Moving the firewall from the perimeter one more step patronize into the network in a defense-in-depth approach.
The firewall functions now work on the critical point in the network, Network Interface measure (NIC). EFW works on lower network layers, unlike packet based firewalls running at higher layers on the local host. By processing data at the lower layers, EFW puke improve processing speed and increase performance.
In addition, it is non as easy to deactivate EFW as with software based firewalls because the attacker needs to adopt a physical plan of attack to the host computer in order to disable the NIC.
However, in that location has always been a trade-off between the performance and utilities of a security system. One cannot expect from a particular security system to comprise all of the utilities and also have the scoop out performance.
1.2 Statement of the Problem
In recent years data breaches have been of great concern and burden to cooperate bodies and organization with networked systems. whence the need for data security arose to ensure integrity, confidentiality and limit access to sensitive data on a need-to-know basis.
Firewalls serve as security mechanisms for checking attempts to hack data....If you want to get a practiced essay, order it on our website: Orderessay
