Firewall Policies

Based on the information security rules of the enterprise, Firewall Policy investigates how the firewall should handle network traffic for certain Internet Protocol addresses as well as deal with ranges, protocols, applications, and content kinds. The policy also provides precise instructions on how to handle modifications to the established rules (Ali, Al-Shaer & Samak, 2014).
An Internet firewall is essential for several reasons, including its capacity to protect sensitive data and advice on when firewalls are required and advised. All of the confidential computerized information is protected by a firewall. In the case of a business owner, not only is privacy important from a better perspective, but one should ensure their customers personal business information is going to be safe with them by providing adequate security and these will determine the times when the data is stored and also when to process it. Also, it raises awareness on the importance of a properly installed firewall as one will be able to tell of any malware in their devices (Vanikalyani, Avinash & Pandarinath, 2014).

A firewall policy is created by improving one's designs, in that when one wants to come up with a new policy, they should first start with the basics. The ones that already exist should be checked to ensure that they are working before coming up with a more complicated. While creating a firewall policy, one should avoid using just any setting as a service and be much more specific and also, when creating firewall addresses or other objects, give them a particular name that aids to pinpoint that object in the future. Using the Comment field for the same purpose makes it easier to identify the purpose of each policy. While creating a firewall, one should make a backup of any information before deleting the current one to ensure you find it when needed (Ali et al., 2014).
