...organization is different in the way that it communicates internally and with its vendors and customers and in the kinds of information that it sends over the Internet. Practicing strong computer security is a nonnegotiable requirement for organizations doing business today. However, building security into an existing corporate culture is a complex undertaking. Every organization has a security culture, and each is as unique as the organization itself. Security culture can be collaborative or argumentative, structured or unstructured. Security can be an integral part of a process beginning at the project-definition stage, or a separate process added on to an existing project. It can be ingrained or reactive. Information security is the protection of information from a wide range of threats in order to ensure business continuity, minimize business risk, and maximize return on investments and business opportunities. Security issues are unknowingly generated via employees using consumer electronics in their homes. As more consumer communications and devices enter the corporate enterprise security professionals need to consider the risks for business security. Things to consider included IM, gmail, iphones, un-secure home networks, etc. Employees are using these devices at home and in the workplace. . The first and most important strategy is to align information security with business strategy. The higher the value, the bigger the target, the greater the damage and overall risk to the...

...What is the relationship between a TCP and UDP packet? Will any specific transaction usually involve both types of packets? A TCP Packet sends information, and reports back to the sender on progress to assure that information has been sent and received. UDP on the other hand is designed more for speed after establishing a connection and is used to strive for the fastest data retrieval rate as possible, but for this type of packet, it’s less important that it reports back. I don’t believe there will be specific transactions that involve both types of packets. But TCP is better for assuring that data is being received completely, but UDP focuses on assuring data is retrieved as quickly as possible. 3. How is an application layer firewall different from a packet-filtering firewall? Why an application layer firewall is sometimes called a proxy server? A packet-filtering firewall only allows “a particular packet with a particular source, destination, and port address to enter”. An application layer firewall is sometimes called a proxy server because it “runs special software that acts as a proxy for a service request” It is more to deal with outgoing connections and making connections within the DMZ zone of an organization. 4. How is static filtering different from dynamic filtering of packets? Which is perceived to offer improved security? Static filtering works with rules that are already designated or “developed and installed with the firewall” and only a person...

...As an Information Security Engineer for a large multi-international corporation, that has just suffered multiple security breaches that have threatened customers' trust in the fact that their confidential data and financial assets such as Credit-card information; one must implement security measures that will protect the network through a vulnerable wireless connection within the organization, while also providing a security plan that will protect against weak access-control policies within the organization. The first step of protecting against Credit-card information through a vulnerable wireless connection within the organization would be to first protect your wireless broadband from cyber-attacks, which don’t involve any costly measures. One must always remember to lock down the wireless network. By default the password for your panel is often a standard one set-up by the manufacturer (for example ‘admin’). It’s very important that you change this as soon as possible, because it would me that many hackers would already have the password for it. When picking a strong password use a case sensitive combination of alphabets and numbers, six characters and more. Also remember to make it something unique and not the same as something else like your Facebook or Twitter password. Next too consider is the fact that most routers come with a WEP or WPA key built in for good measure, and each router has a different code so there is no need to stress when it comes to this aspect. Since...

...Principles of Information Security, 4th Edition 1 Chapter 1 1 Review Questions 1. What is the difference between a threat agent and a threat? A threat agent is the facilitator of an attack, whereas a threat is a category of objects, persons, or other entities that represents a potential danger to an asset. Threats are always present. Some threats manifest themselves in accidental occurrences and others are purposeful. Fire is a threat; however, a fire that has begun in a building is an attack. If an arsonist set the fire then the arsonist is the threat agent. If an accidental electrical short started the fire, the short is the threat agent. 2. What is the difference between vulnerability and exposure? Vulnerability is a weaknesses or fault in a system or protection mechanism that opens it to attack or damage. Exposure is a condition or state of being exposed. In information security, exposure exists when a vulnerability known to an attacker is present. 3. How is infrastructure protection (assuring the security of utility services) related to information security? The availability of information assets is dependent on having information systems that are reliable and that remain highly available. 4. What type of security was dominant in the early years of computing? In the early years of computing when security was addressed at all, it dealt only with the physical security of the computers themselves and not the data or...

...1. Information security is more of a management issue because it is up to management to decide what end users should have access to and what they should not. Also technology can only do what it is told to do but if management sets up training to teach end users about the threats of say opening an unknown email then the company is safer. 2. Without data an organization loses its record of transactions and/or its ability to deliver value to its customers. Page 42 Principles of Information Security 3. Both general and It management 4. It has created more and the reason why is it is much easier to spread viruses, worms, etc. now that the can get from system to system without having to attach to a physical disc. 5. Information extortion occurs when an attacker or trusted insider steals information from a computer system and demands compensation for its return or for an agreement not to disclose it. Page 60 Principles of Information Security. An example would be if someone would steal the latest album from a well-known artist before its release date and demanded to be paid or it would be released onto the internet. 6. Employees are one of the biggest threats for several reasons the can accidently allow someone access to the system by installing a back door or it is possible for them to become angry with the company and just hand out IP to rival companies. It is also possible that they could accidently delete valuable data from the system that has no backup. 7. Make sure nobody...

...implementing information security to protect the ability of the organization to function. They must set policy and operate the organization in a manner that complies with the laws that govern the use of technology. Technology alone cannot solve information security issues. Management must make policy choices and enforce those policies to protect the value of the organization’s data. 2. Data is important to an organization because without it an organization will lose its record of transactions and/or its ability to furnish valuable deliverables to its customers. Other assets that require protection include the ability of the organization to function, the safe operation of applications, and technology assets. 3. Both general management and IT management are responsible for implementing information security. 4. The implementation of networking technology has created more risk for businesses that use information technology because business networks are now connected to the internet and other networks external to the organization. This has made it easier for people to gain unauthorized access to the organization’s networks. 5. Information extortion is when an attacker steals information from a computer system and demands compensation for its return or for an agreement not to disclose it. One example could be someone that gains access to PII such as SSN’s through a company’s database and ransoms the information for money. If not paid, he could sell the information on the black...

...Computer Security Anyone would agree that private information needs to remain private. To keep any information secured takes a lot of time and effort. In order to make sure the information will be kept private the information itself has to satisfy certain properties in order to make sure the information is kept secured. “Confidentiality, integrity and availability have been considered the three core principles of information security for more than two decades. They are commonly referred to as the CIA triad” (Cyber Secure Online, 2013). When designing security controls you will definitely be addressing one or more of these core principles. Even though these principles were considered core security professionals realized that the focus cannot solely be on these three principles alone. The CIA triad was expanded by adding an additional four principles that have enhanced and would now have a more sufficient in protecting confidential information. Listed here are the seven principles of the Expanded CIA triad: Confidentiality, Integrity, Availability, Possession, Authenticity, Utility, and Accuracy. As stated above many of the security professionals did not want all concentration to be on the original three, so it made sense to expand. This will ensure that the information that needs to be protected is protected thoroughly. “Each time an information technology team installs a software application or computer server, analyzes an data transport method, creates a database...
