Trusted Computer System Evaluation Criteria

A computer is secure if you can depend on it and its software to behave as you expect I this assignment I will writer about how Linux provides security to you information. The major technical areas of computer security are usually represented by CIA confidentiality, integrity, and authentication or availability. It means that information cannot access by unauthorized people.

One of the important part of system administration should be secure, so it is very important to understand which factors can affect security inside and outside our system. There are many key decisions that have to be made, for example, what server operating system should a system use to which

The specific purpose of this paper is to describe the authentication process and to describe how this and other information security considerations will affect the design and development process for new information systems.

The purpose of this paper is to explore and assess computer security as it relates to Aircraft Solutions. Aircraft Solutions provides products and services to a range of companies that require highly specialized skills. Information is accessed by internal and external users via their Business

Cyber Security is the protection applied to information, computers, computer networks, information stored therein from unauthorized access, disruption, disclosure, use, modification or destruction. It is the security provided in terms of three elements called confidentiality, availability and

“The Federal Information Processing Standards Publication Series of the National Institute of Standards and Technology (NIST) is the official series of publications relating to standards and guidelines adopted and promulgated under the provisions of Section 5131 of the Information Technology Management Reform Act of 1996 (Public Law 104-106) and the Federal Information Security Management Act of 2002 (Public Law 107-347)” ("FIPS PUB 199," 2004). In this paper, FIPS PUB 199 has been chosen as the security standard used by State of Maryland Department of information technology. This standard addresses to develop standards for categorizing information and information systems. On the other hand, ISO/IEC 27001 is the other standard not used by State of Maryland which has been discussed as a contrast standard.

In today’s IT world every organization has a responsibility to protect the information and sensitive data they have. Protecting data is not only responsibility of security and IT staff but every individual is involved in protecting the information. The risks to information security are not digital only, but it involves technology, people and process that an organization may have. These threats may represent the problems that are associated to complex and expensive solution, but doing nothing about these risks is not the solution.

Any enterprise has to pay special attention to computer security. Computer security is a field that is concerned with the control of risks related to computer use. A primary focus should be on the external threats to the computing environment. In enterprise with branches cross country, it is important to allow information from "trusted" external sources, and disallow intrusion from anonymous or non-trusted sources. In a secure system, the authorized users of that system are still

4. Which of the following components can be used to measure the confidence in any authentication system?

As such, he introduces a technique of identifying a spectrum of potential vulnerabilities and suggests procedures to deal with them. Systems Specification and High Order Language Implementation are categorized as items of high risk to attacks. Security Policy and Machine Language Implementation are classified as items of moderate risk of being vulnerable to attacks. Circuits Electronics and Device Physics are of low and very low risks respectively. He also discusses potential threats such as deceiving operating systems to grant access to file or data to unauthorized users through direct (overt) and indirect (convert) channels. Walker also says that lack of precise definition of trusted operating systems and the higher cost of building them are the significant drawbacks faced by the vendors. Vendors are concerned that if they build trusted operating systems, they might not be accepted by their customers. The only solution suggested by the author was to have someone or a company builds it, shares the technology used, and convinces the general public on the significance of it. Once it becomes accepted, then there will be a widespread use of trusted computer operating systems.

Assessments are used to determine if sufficient security is being utilized to protect federal data. These requirements are put in place to identify vulnerabilities within the information security infrastructure. It rates potential weak points that may be caused if vulnerability was found and a plan of action must be developed and executed to elevate found vulnerabilities to meet desire security standards. System administrators are obligated to assist their higher levels with found assessment and suggestions on how to improve the information system infrastructure. Scanning the system infrastructure is one of many modes used to assess the strength of information security. Several software, such as QualysGuard, have been designed to scan system architecture. QualysGuard is an automated suite that simplifies information security measures by rendering critical security intelligence. The suite offers full protection of all information security systems, auditing, and compliance assessments. Accrediting and

An information security benchmark model (CIA) an acronym for information Confidentiality, Integrity and Availability can be used to evaluate the solution

The article, which addresses security loopholes in modern computing environments, by Loscocco et al highlights what is and has been being done security wise in the past and how secure these implementations were and going forward what should be done to ensure in depth security which guarantees system wide security (1998). The article first explains features of secure operating system and why current systems implemented under the notion of application space security ultimately failed to safe guard the integrity and confidentiality of our assets. The article then continued with general examples of access control and cryptography implemented in the application space with no or little support from operating system and showed their vulnerabilities to attacks such as tampering, bypassing and spoofing. The article supplied real-life examples to support the evidence that building security in the application space without secure operating system is meaningless. The article raised concrete examples on mobile code security, Kerberos network authentication service, IPSEC and SSL network security protocols and firewall. The paper finally put an interesting remark that security implemented in application space without secure operating system is like “building a house in a pile of sand” and it also emphasized that secure operating system without better security on the
