Introduce the concept of using information security models (why are they important). Two fundamental concepts in computer and information security are the security model, which outlines how security is to be implemented. Basically providing a blueprint and the architecture of a computer system, which fulfills this blueprint. A security model is a statement that outlines the requirements necessary to properly support and implement a certain security policy. A security model provides a deeper explanation of how a computer operating system should be developed to properly support a specific security policy (Whitman, 2014).
Explain that some security architecture models are implemented into computer hardware and software, some are implemented as policies and practices, and some encompass both Information security is made up of three main attributes: Availability is the prevention of loss of access to resources and data. Integrity is the prevention of unauthorized modification of data, and Confidentiality is the prevention

It uses a state machine model and is very similar to the Bell-LaPadula model. Biba addresses the integrity of data being threatened when subjects at lower integrity levels are able to write to objects at higher integrity levels and when subjects can read data at lower levels. If implemented and enforced properly, the Biba model prevents data from any integrity level from flowing to a higher integrity level. Biba has two main rules to provide this type of protection. The first rule, referred to as “no write up,” states that a subject cannot write data to an object at a higher integrity level. The second rule, referred to as “no read down,” states that a subject cannot read data from a lower integrity level. This second rule might sound a little goofy, but it is protecting the subject and data at a higher integrity level from being corrupted by data in a lower integrity level (Whitman,
The integrated threat theory model consists of four types of threats that can lead to prejudice. These threats are: realistic threats, symbolic threats, intergroup anxiety, and negative stereotypes. Realistic threats are posed by the outgroup and have several types of consequence and impact. They can either be threats of war, threats to political and/or economic power of the ingroup, and threats to physical and/or material well-being of the ingroup and its members. Symbolic threats is usually based on perceived group differences in morals, values, standards, beliefs, and attitudes. Symbolic threats are also threats to the ingroup’s worldview and these threats arise because the ingroup believes that its system of values are morally correct.
The physical security field can be broken down into two very general but separate areas: types of security and security components. The Types of Security outlines different areas or sectors where why and how security is conducted differ. Security components break down Physical Security even further, speaking to the more intricate areas of any Security type or team.
When working practitioners must not only protect the children they work with when in the school setting and off site, but also themselves. Whether in school or off-site the school safeguarding policy should be referred to, to give guidance and adhered to at all times.
There are two theories that attempt to explain how to prevent corporate crime: deterrence theory and compliance theory. Theories of deterrence focus on preventing individuals from committing crimes based on a fear of the consequences. Compliance theories, on the other hand, concentrate on the power of regulatory agencies to encourage individuals to comply with the law before crimes are committed. The biggest difference in these theories is the way that laws are enforced on corporate criminals. Deterrence theories rely on criminal prosecutions to prevent corporate crime after the crime has already been committed (ex-post), where as compliance theories focus regulatory agencies that encourage compliance with the law before the crime takes place (ex-ante).
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Safeguarding means keeping vulnerable children and adults safe from harm and abuse. It also means to ensure that people are supported to keep well and healthy and have access to health care should they require it.
Authenticity within the culture of popular music is an issue that has been discussed for many years as it can be a huge selling point, it can cause society to either loathe or love a performing artist on how 'authentic' their persona and music is. Moore (2002) brings forward this idea in the article ‘Authenticity as Authentication’:
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help to stop unauthorized users or intruders from accessing any part of a computer system. Detection helps one to determine whether or not someone attempted to break into a computer system, if they were successful, and what they may have done.
There are number of different models proposed as framework for information security but one of the best model is McCumber model which was designed by John McCumber. In this model the elements to be studied are organized in a cube structure, in which each axis indicates a dissimilar viewpoint of some information security issue and there are three major modules in each axis. This model with 27 little cubes all organized together looks similar like a Rubik's cube. There are three axes in the cube they are: goals desired, Information states, and measures to be taken. At the intersection of three axes you can research on all angles of an information security problem.
Conflict theory are perspective in sociology psychology that accentuate the social, political, or material inequality of a social group, that analysis the broad socio-political system, or that weaken from structural functionalism and ideological conservatism. With conflict theory, you will see tensions, status, and power are unevenly distributed between groups in society, which these conflicts become the purpose of social change. Conflict theory usually arise due to competition and limited resource that is feed by domination and power, rather than consensus and conformity. This is seen a lot on macro level. As a social worker, you will see and use conflict theory throughout your professional.
For thousands of years cryptography and encryption have been used to secure communication. Military communication has been the leader of the use of cryptography and the advancements. From the start of the internet there has been a greater need for the use of cryptography. The computer had been invented in the late 1960s but there was not a widespread market for the use of computers really until the late 1980s, where the World Wide Web was invented in 1989. This new method of communication has called for a large need for information security. The internet allows people to communicate sensitive information, and if received into the wrong hands can cause many problems for that person.
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
Nowadays, the information is the most treasured asset in an organization, due to it along with the experience represents the input necessary to take appropriate decisions and consequently to have success in the business. Almost all the information and knowledge related with the processes business, goods and services offered by a company, is processed, managed and stored through technology and information systems, thus the security of information has become increasingly important and plays a critical role in the enterprise government.
Security is very important for many different reasons. A nation must insure their safety as a whole, as well as the persons living in the nation. It is equally important that the nation's economy is stable and growing. Security is something that every nation deals with, in many different ways. It is a way that nations come to together and create allies. However, it is also a way for nations to create enemies. There are a variety of concerns that require attention around the world including state security, human security, and economic security. Political and economic relations impact each of these security issues different proven by history and present events around the world.
