This paper describes about firewall management as one of the components in information assurance, which elaborates the importance of firewalls on the operation system. Illustrating the example of the online transaction that can use firewall management to mitigate the risks of severe consequences from cyberattacks. Besides, there are some limitation of firewalls as well that we have to consider in operating the system even if the firewall is protecting the system.
Introduction
Nowadays, information assurance (IA) plays an important role in every business sector, which is the key to dependable management decision-making, users trust, business continuity and good corporate governance (Ezingeard, McFadzean, & Birchall ,2005). As quality and

Integrity is to ensure that information is not corrupted. Lastly, availability is to ensure that information is always ready to support the demand of users. There are many diverse kinds of information assurance services in the market nowadays, which provide independent validation and verification services with innovative software or applications towards the organization’s system (Ezingeard, McFadzean, & Birchall, 2005). According to Managed Security. (N.d.), Dell security service provides capability of protection towards the network, essential internal asset, remote users and important information. In this paper, I would like to expound one of the critical services as information assurance, named firewall management, which is the important component in the part of information assurance in every organization.
Firewall Management
What is Firewall Management? According to Managed Firewall (N.d.), Firewall management is a security service which prevent unauthorized access and costly breaches in the organization’s system. This service requires a high level of expertise in order to manage and control the system, in which the network traffic must be monitored incessantly to protect from cyberattacks before the devastation is done. As mentioned in Harrison (2011), it defines firewall as gatekeepers for the corporate network and data center perimeters. The procedure of Firewall is to control and scan the network
Information security is a business requirement and also a legal requirement, subsequently firewalls are set up as security from viruses and backups are implemented to ensure no information is lost.
This project identifies a two possible issues that can happen during the system operations like hacking or data loss due to improper security provided to the company branches and there is no proper infrastructure of the firewall for the network structure. The aircraft security policy result in failure due to their two year reset program.
The particular operate on the firewall in a organization is actually in order that just about all unwanted things to do are usually impeded which includes cyberpunks that will get critical and also delicate information on the business. Hacking is a really unsafe exercising wherever offender may access quite information a business has and also use this information throughout blackmailing the business as well as customers. Marketing software’s additionally takes on a significant position throughout acquiring the businesses multilevel protection. It has got the features involving sensing infections that could invasion a corporation and also help to make a corporation shed its critical information. AVG is just about the best ensuring that multilevel protection is actually preserved. The virus separate from the virus that detects other virus’ have the ability to use web firewall and also find virtually any spyware and adware that an organization may be being affected by. It really is accurate that an organization will need to have both hardware components and
Firewall: A firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analysing the data packets and
“Security needs to be addressed as a continued lifecycle to be effective. Daily, there are new attack signatures being developed, viruses and worms being written, natural disasters occurring, changes in the organization workplace taking place and new technologies evolving, these all effect the security posture in the organization” (King, 2002). This being said, it is important to evaluate firewall and router rule sets more frequently. The possible threats against this policy include improperly configured network infrastructure which leads to a domino effect that could start with malicious programming which could end in data loss. Many of these threats may be unintentional as some users may not be aware of the risks and how their processes and procedures open the door for such attacks. For this reason alone, a more frequent evaluation is needed. This vulnerability could lead to data loss and the exposure of trade secrets, client lists and product design. The exposure of such information for most companies could mean a financial collapse as it no longer has the competitive edge that makes it the industry leader. While the likelihood of this threat is very high, “security risks to the network exist if users do not follow the security policy. Security weaknesses emerge when there is no clear cut or written security policy document. A security policy meets these goals:
A firewall protects networked computers from intentional hostile intrusion that could compromise confidentiality or result in data corruption or denial of service. It may be a hardware device or a software program running on a secure host computer. It must have at least two network interfaces, one of the network it is intended to protect, and one for the network it exposed
This is an open exposure due to the uncertainties of the internet. Controlling access to information systems and associated networks is necessary for the preservation of their confidentiality, integrity, and availability. Confidentiality assures that the information is not disclosed to unauthorized persons or processes. Any automated attacks or personal attack or attack to exploit the company secrets/statistics/data is the biggest threat to that may occur without the firewall.
Who is to audit firewall effectiveness and how often? If the firewall is never audited the organization will never know if it is effectively protecting them.
Firewalls are set up on computers to help protect computers and other devices from attacks from potentially harmful websites and other resources. Proxies are servers that act as a middle man for computers. They allow users to make indirect connections to other servers. The LAN-to-WAN domain is where the infrastructure connects to the Internet. Updates, firewalls and proxies will help to keep things running and help to keep it protected.
Despite its impact ping sweeps and port scans are best understood as a huge security threat on today's company's network system.
Identification of controls already in place – including policies, firewalls, applications, intrusion and detection prevention systems, virtual private networks, data loss prevention and encryption.
Firewalls are also important because they are a single point where you can impose security and auditing. If someone attacks a computer system by dialing in with a modem, tracing the perpetrator is impossible. In contrast, the firewall can act as an effective phone tap and tracing tool. Firewalls also provide an important logging and auditing function, summarizing topics such as the kinds and amount of traffic that passed through it and how many attempted break-ins occurred recently.
In an e-commerce world, organizations are susceptible to hackers and intruders. Thus creating the information technology protection systems which is used to reduce the possibility of intrusions from occurring. Intrusions occur by uninvited outsiders (sometimes intruders can be internal users like employees) who try to access an organization’s information system using the internet with the intent to gain competitive advantage of some sort. Organizations depend on security technology to avoid loss from security breach, as well as to improve their efficiency and effectiveness. However, firewalls are also vulnerable to errors, and implementing a security technology comes with challenges and critical decisions that can possibly cause a financial burden on the organization if done without seriousness and commitment. “Information security is about managing risk, and managing risk is about discovering and measuring threats to information assets; and taking actions to respond to those threats” (Al-Awadi, & Renaud, 2007, p.3). This paper will discuss a few aspects that are involved with firewalls and intrusion detection systems.
The always and ever increasing quantity of products with IP routers are incorporating packet filtering as a tool to help in improving the network security if utilized in the proper way, packet filtering is a great tool for a network’s security or networks administrators that are security conscious but in order for it to be used effectively one must have an in-depth understanding of its many capabilities and weaknesses, advantages and disadvantages and what type of particular protocol that the filters are being applied to. This paper begin by defining firewall and identifying the different types of firewall then goes into Packet filtering describing some of the characteristics and some of the application protocol then the paper identified
