Improving a Rule Base and Firewall Selection Parameters
It is imperative that companies develop strategies that will assist them in the protecting their information systems against the individuals who may want to penetrate their systems so as to steal information. In that case, it is imperative that companies irrespective of their sizes and nature of business operations institute measures to protect their systems. In most cases, it is tough for the network administrators to select the appropriate strategy to employ in protecting the company’s systems and guarantee that it is going to meet the demands of the company. In the cases of the company development of the necessary firewall, it is clear that there are numerous parameters that have to be assessed appropriately when assessing the firewall solution for the company’s network (Weaver, Weaver &Farwood, 2013). It is imperative that there is an adequate assessment each of the following parameters and assessed deeply before the making of any selection.
The assessment of the most appropriate firewall elements encompasses:
- The number of users. In this case, the assessment of the type of firewall encompasses an evaluation of the number of users who are going to be using the company’s network at any given time. The assessment of the number of the users follows that the more the number that is using the network, the higher the class of firewall that will be needed (Ostrovsky, Rodenski& SELA Group, 2014). The firewalls that are available are categorized from the small office, home office to the most expensive firewall that is meant to protect enterprises.
- The random access memory. The random, access memory as the additional attribute that is taken into consideration when choosing the firewall encompasses the assertion that the appropriate Ram is extremely vital to the development of a reliable firewall and additionally ensuring that it functions appropriately. The two models of RAM that hold significance in assessing their compatibility with the firewall encompasses the dynamic RAM and the static RAM (Oppenheimer, 2010). It is imperative that the organizational networks that are used by few users use the dynamic RAM.
- It is imperative that firewalls can undertake network address translation (NAT) functionality that allows a business to manage the ability to translate the diverse illegal or private IP addressed into the legal public address and consequently guard the anatomy of the network.
- The inbound as well as outbound filtering. It is additionally imperative that firewalls manage to detect that diverse content that is passing through it in either direction. In this case, it is imperative that the firewall manages to filter the any malicious content that comes to the network in addition to the content that is going out of the network (Coulouris, Dollimore, Kindberg& Blair, 2011).
- Stealth mode. One of the attributes that define an effective firewall is the fact that it needs to have the ability to place the entire network or certain computers on a network into a stealth mode. In this case, computers are kept hidden from the internet world including the time that they are connected to the internet (Weaver, Weaver &Farwood, 2013).
- Privacy connection. It is additionally imperative that one of the qualities that an effective firewall possesses is that it should be able to block diverse spyware, hijackers along with adware from managing to reach the computer.
- Application integrity. It is imperative that a firewall can monitor the files a machine is connected to the network and comprehend how the files could be modified or launched. It is imperative that any forms of evil modifications are notified to the users (Coulouris, Dollimore, Kindberg& Blair, 2011).
- Detection of intrusion. It is imperative that a firewall scans the incoming data for all the signatures that are know of methods and consequently notify the users the moment there has been an identification of any form of attack.
- It is additionally imperative that a firewall works transparently and consequently keep on sending notifications to the users relating to the assessment of what is taking place on their firewall.
- Enforcement of security standards. It is imperative that all the users in the organization use to access applications as well as services through similar methods and procedures. The implication of this intervention is that there is going to be a reduction in the rule base as well as a more easily comprehended operating environment (Weaver, Weaver &Farwood, 2013). The only caveat that comes with this strategy is that there has to be time and budget for the training of users in the new procedures, facilitate the installation of software as well as provide additional IT support technicians.
- Firewall security policy. It is imperative that a firewall has a tight security policy that ensures that it is protected from challenges that come with the users who fail to comply with the requirements. In this case, it is imperative that there is a review of the firewall rule bases that the organization has employed in their firewall as a way of ensuring that they are protected (Weaver, Weaver &Farwood, 2013). The attribute encompasses a minimizing the impact that it has on the organization’s production environment.
