Firewall is a process utilized for controlling traffic of network within and external to internal network of an organization. In most situations, such systems have 2 interfaces of networks with one being external and other being internal (Jadhav and Agrawal 753-756). The process of firewall can engage in controlling tightly what has been permitted for traversing from a side to the other. A company wishing to deliver external web server access can result in restricting arriving traffic at the firewall. This is excluding the 80 port. All the related traffic cannot be allowed due to the presence of internalized network.
As one evaluated the firewalls for their customers or to utilize a part of the offering of security as a service, there are several solutions to look at. It becomes essential to look at either performance or security and in most of the cases, both have to be looked at (Chen et al. 82-94). A firewall without a doubt needs to be such that it enhances securities and performed tasks such as limited access of remote nature to the network, resulting in blocking a port or making attempts at scanning IP and also stopping essential loggers from keystrokes monitoring. Taking the time for educating the customers over the roles of firewall is essential to prohibit access of unauthorized nature and prevent files of malicious nature from being obtained through the networks.
This is henceforth an essential part of a solution of security (Eslahi et al. 123-134). However as crucial as security of network is, one cannot allow it to start trumping needs of a business for performance of computing. The customers are such that they require the ability of optimizing productivity so that they have the ability of providing a customer service level which makes them not only competitive but also highly productive in terms of resources.
