Firewall Security Policy Pathways Industries

An extranet is part of a company’s internet that can be used outside of the company by employees, client’s suppliers or vendors, so they are able to communicate within the company in a private virtual space. Extranet can be purchased from an application service provider, who can update and maintain the software for the company (Rouse, 2004). Extranet is considered to be a controlled private network that allows others to gain some of the company’s private information; it is a part of a company’s internet that is extended to outside uses (Shofield, 2010). Today most companies use extranet even-though it is expensive to maintain and security can also be an issue when sending valuable information, but with a firewall in place can help a company with having important information from getting into the wrong hands, even though it is a private network, security can be an issue when sending valuable information a company must make sure they have a good firewall in place. There are a lot of different firewalls a company can purchase, the company should choose wisely and base the decision on the type of information they will be sending and to whom they will be sending it to.

Sunica Music and Movies, a local multimedia chain with four locations would like to switch to a centralized network to handle accounting and inventory as well as starting an Internet-based commerce site. The security policy overview shows the new setup will utilize four types of security policies. These polices have set goals that must be meet in order to achieve and maintain a successful transition.

Firewalls prevent unauthorized users from accessing a private network when it is linked to the Internet. Intrusion detection systems monitor private networks from suspicious network traffic and attempts to access corporate systems. Passwords, tokens, smart cards, and biometric authentication are used to authenticate system users. Antivirus software checks computer systems for infections by viruses and worms and often eliminates the malicious software, while antispyware software combats intrusive and harmful spyware programs (Laudon and Laudon, 2009, p.260)

Discuss the roles and motivations for separately filtering ingress and egress traffic in the enterprise network. Describe separate conditions for both ingress and egress traffic as they transit the network. Discuss: What roles do ingress and egress filtering play in protecting a network? How do protective isolations help to protect a network? Why do we need to separate and isolate the types of traffic?

This IDC study examines the worldwide network security market, including firewall, UTM, IDP, and VPN solutions, from 2011 to 2016. It provides vendor revenue shares and market sizing for 2011 as well as market growth forecasts for 2012–2016.

Thesis Statement: This paper will try to prove that the improper management of firewalls and the lack of strong security policies used in enterprises will cause data breaches from within the enterprises. To try and prove this, the paper will shed light on various data breach scams that occurred to companies such as Target, Home Depot, Ashley Madison and OPM. It will also try to create a model for ideal security policy making for companies in the e-commerce domain.

There are different types of firewalls that analyze each with different capabilities of network traffic and allow or block certain instances, by comparing traffic characteristics to the existing guidelines. To understand the capabilities of any type of firewall and design of firewall policies and the acquisition of firewall technology, the requirements of an enterprise are effectively addressed to achieve critical protection for network traffic.This document provides an overview of firewall technologies and discusses their security capabilities and relative advantages and disadvantages in detail. It also provides examples of where firewalls can be placed within networks and the implications of deploying firewalls in particular locations. The document also makes recommendations for establishing firewall policies and for selecting, configuring, testing, deploying, and managing firewall solutions. To improve the effectiveness and security of their firewalls, organizations should implement the following

We can use flows or sessions as a way to determine whether traffic attempting to traverse the firewall is legitimate. We control the state-checking components resident in Juniper Firewall by configuring "flow" settings. These settings allow you to configure state checking for various conditions on the device. You can use flow settings to protect against TCP hijacking, and to generally ensure that the fire-wall is performing full state processing when desired. We take a case study of attack on a network and perform study of the detection of the malicious packets on a Netscreen Firewall. A new solution for securing enterprise networks will be developed here.

The modern world is being automated in all fields in various aspects. Automation is achieved by the software development and this result in a faster work accomplishment and also in an easy, efficient way. Meanwhile, this progress has also got proportionate threat of misusing the software. As the internet has extended its roots providing access to various networks and also may provide access to inappropriate users. So, it is necessary to protect these networks and this purpose is served by network security. The security levels can be classified into two they are low level security and high level security. Network security includes many components and firewall is one such component that protects a network from various threats. Everything in

The purpose of this policy is to state the requirements to access the network and network resources remotely using the existing Virtual Private Network (VPN) or User VPN.

Monitor all entry way into the organization’s network – it is desirable to have only one access point to and from the network. However, with more than one entrance, it is important that they be all monitored continually, to aid in identifying suspicious network traffic. Abnormal traffic has a high probability that a breach is taking place.

This paper entails a discussion about Intrusion Detection and Prevention Systems. An explanation with reference to what they are, what they are used for, where, why and

The first requirement is that the company must install and maintain a firewall that is properly configured to protect cardholders’ data. All computer systems shall be protected from unauthorized access by untrusted networks. A firewall shall be always be used when entering the system from the Internet as e-commerce, employee Internet access through a desktop browser, employee-email access, a dedicated connection such as business-to-business connections, via wireless networks, or other sources. There needs to be a recognized process that approves and tests all network connections and any changes to system configurations. A current network diagram that depicts all network connections should be also be created, verified, and updated

Intertrode company has determined that the current security countermeasures are insufficient due to increasing number of physical connections which are unauthorized to the company 's network. so, as the previous network designers we have to implement more security countermeasures which are helpful for the present situation of the Intertrode company.

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.
