...Introduction West Suburban bank has worked hard to protect its customer information and the related data that is provided to the bank in order to business with them. In collaboration with Perimeter E-Security Company, West Suburban bank has excellent network security system that recognizes the threats within seconds and figures out a solution to fix the problem. Perimeter E-Security offers excellent information security and messaging services helping many businesses to secure their data from unauthorized users. West Suburban bank took advantage of the services provided by Perimeter E-Security as well in order to protect the assets of their clients. There are hundreds of defense methods however for this paper our major focus will be on the six defenses used by West Suburban bank in order to provide best security services to its clients and protect its information. We will be looking at firewalls, data security, Internet security, application security, access control and anti spyware defenses. Firewalls defense Firewalls implement security at every layer. Firewalls are barriers between a trusted network or PC and the untrustworthy Internet, it is a network node consisting of both hardware and software that isolates a private network from a public network. On the Internet, the data and requests sent from one computer to another are broken into segments called packets. Each packet contains the Internet address of the computer sending the data, as well as the Internet address...

...Contrast Three Intrusion Detection Systems (IDS) Devon Hopkins Webster University Introduction In the today’s society security is of paramount importance, whether it’s your business, home, vehicle, or computer. Companies are responsible for securing their employees, work area and the technology they use to operate their business. On a daily basis companies are under attack making them vulnerable to more and more worms, viruses, denial of service (DoS) attacks and hacking, shutting them down for various periods of times. With the advance technology more and more companies are storing information digitally. Having unsecure networks are leading to enormous amount of private information being public. The networks should protect data and maintain confidentiality, integrity and availability of the network. Companies should implement intrusion detection systems (IDS) because hackers are smarter and their intrusions are getting harder to trace. Intrusion Detection System An intrusion detection system or IDS is a system that attempts to identify intrusions, which can be defined to be unauthorized uses, misuses, or abuses of the computer systems by either authorized users or external perpetrators [1]. The in the past the major ways that intrusion detection systems were described were host based IDS (HIDS) and network based IDS (NIDS). An addition to the IDS family is perimeter intrusion detection systems (PIDS). A perimeter intrusion detection system will be installed within the...

Conclusion 13 I. Introduction Access control mechanisms operate at a number of levels in a system, from applications down through the operating system to the hardware. Higher-level mechanisms can be more expressive, but also tend to be more vulnerable to attack, for a variety of reasons ranging from intrinsic complexity to implementer skill levels. Most attacks involve the opportunistic exploitation of bugs; and software that is very large, very widely used, or both (as with operating systems) is particularly likely to have security bugs found and publicized. Operating systems are also vulnerable to environmental changes that undermine the assumptions used in their design. The main function of access control in computer operating systems is to limit the damage that can be done by particular groups, users, and programs whether through error or malice. This project will be conducted in two main checkpoints: * Phase I: The first step in this project is to analyze risk and develop a mitigation plan to identify which assets are more critical. Determining what systems rely on each other...

...SECURITY ESSENTIALS IMPACT OF SECURITY BREACHES • Security breaches affect organizations in a variety of ways. They often result in the following: • Loss of revenue • Damage to the reputation of the organization • Loss or compromise of data • Interruption of business processes • Damage to customer confidence • Damage to investor confidence • Legal Consequences -- In many states/countries, legal consequences are associated with the failure to secure the system—for example, Sarbanes Oxley, HIPAA, GLBA, California SB 1386. • Security breaches can have far-reaching effects. When there is a perceived or real security weakness, the organization must take immediate action to ensure that the weakness is removed and the damage is limited. • Many organizations now have customer-facing services—for example, websites. Customers may be the first people to notice the result of an attack. Therefore, it is essential that the customer-facing side of the business be as secure as possible. SECURITY RISK MANAGEMENT DISCIPLINE (SRMD) PROCESSES In this topic, we will discuss security risk management discipline (SRMD). Specifically, we will discuss: The three processes of SRMD - • Assessment • Development and implementation • Operation Assessment involves • Asset assessment and valuation. • Identifying security risks with STRIDE. • Analyzing...

...Mr. Cameron, Sir, I would be happy to discuss our perimeter defenses. When defining the perimeter we must first ask, are we discussing a physical or a logical (computer) layer of defense? When you observed the guards, fences, and TV cameras, you were observing the physical perimeter defenses. When your colleague mentioned his network perimeter, he was referring to the defenses established to protect your information technology systems (networks, computers, data storage devices, and information). Network defenses include a variety of both hardware and software resources that mimic the function of guards, fences, and TV cameras, but focus on the protection of computer systems and information. What follows is not an all-inclusive list of network defenses, however, they are some of the more common examples that support information security. Like traffic cops, routers direct electronic media traffic in and out of our networks. A router is typically the first and last line of defense as it is commonly on the outskirts of the network defense perimeter. Picking up where the router left off, a firewall operates on a specified set of rules which determine what is allowed to pass. The different types of firewalls include: (a) static packet filters, (b) stateful firewalls, and (c) proxies. Firewalls do not necessarily know what legitimate traffic...

...Coursework Assignment Title: Perimeter Network Security System Outline Requirements The University is based in Glasgow, and provides higher education services to its students and staff. It is located on a single campus called Campus A. Students and staff use the network services from hosts on various different user networks, as shown in Figure 1 . Due to an increasing number of security violations, a possible redesign of the network infrastructure is to be investigated. You have been hired as a consultant to propose security enhancements, and produce a report. The aim of the exercise is to present a possible solution to the problem at hand by creating a prototype of the new network security infrastructure. This new design should tackle the following components: Provide best practice network egress and ingress filtering at the network perimeter. Create a perimeter firewall, with an appropriate topology to provide the organisations services, including public web, and mail servers. The firewall should have a closed security stance, and provide public services in a secure way. Provide secure access to all devices, from the security management subnet. Additionally, research should be carried out into increasingly common Advanced Persistent Threats (APT), and ways to defend against these using network defenses. This part of the coursework will be research only and be confined to a part of the Research Section. You will be required...

...Physical Security Physical Security Physical Security is all around us today. Every organization will have some sort of physical security. This could be anything from locks on doors and windows, fences around their organization, alarm systems, etc. Physical security is known as the action in which an organization can take to help protect themselves as well as their assets against those who want to steal or sabotage your organization. There are three different types of levels of physical protection. These levels are known as “your outer perimeter, your inner perimeter and your interior. If you can implement two or three forms of security at each level, then you will more than likely have an effective physical security system (Deutsch, 2013). Core concepts of physical security are known as the outer perimeter security, your inner perimeter, and finally you’re interior of your organization. Outer perimeter is known as your property and within your property lines in which you own. When an organization wants to secure their outer perimeter, they will put up fences to secure their organization within the fences. The goal of outer perimeter security is to be able to control who you want to walk and drive on your property. Fences are not the only outer perimeter security you may put up, armed guards who patrol the inside of the fence line as well as the outside fence line is considered outer perimeter security as well. “In deciding what type of perimeter security to implement...

...Imagine you are the manager of an information security program. Determine which you believe to be the most useful and justify your answer. Internal pen-testing takes a different approach -- one that simulates what an insider attack could accomplish. The target is typically the same as external pen-testing, but the major differentiator is the "attacker" either has some sort of authorized access or is starting from a point within the internal network. Insider attacks have the potential of being much more devastating than an external attack because insiders already have the knowledge of what's important within a network and where it's located, something that external attackers don't usually know from the start. As a manager, I have to keep in mind that, The goal of the pen-test is to access specific servers and crown jewels within the internal network by exploiting externally exposed servers, clients, and people. Whether it's an exploit against a vulnerable Web application or tricking a user into giving you his password over the phone, allowing access to the VPN, the end game is getting from the outside to the inside. An "external" penetration test will examine the various resources available from anyone outside the security perimeter (i.e., the firewall). This testing could include the web/email servers, dial-in, wireless and VPN access. The "internal" penetration test will examine resources available to anyone inside the security perimeter. This could include employees, contractors...
