During its lifetime, information may plan through many different information processing systems and through many different parts of information processing systems. There are many different ways the information and security systems can be threatened.
To fully protect the information during its lifetime, each component of the information processing system must have its own protection mechanisms. The building up, layering on and overlapping of security measures is called "defense in security.
The three types of controls can be used to form the basis upon which to build a defense in depth strategy. With this approach, defense in depth can be conceptualized as three distinct layers or planes laid one on top of the other. Beings make decisions through cognitive dissonance insight into defense in depth can be gained by thinking of it as forming the layers of an onion, with data at the plan of the onion, people the next plan layer of the onion, and network securityhost-based security and application security forming the outermost layers of the onion.
Both perspectives are equally valid, and each provides plan insight into the implementation of a security defense in depth strategy. Security classification for information[ security ] An important aspect of information security and risk management is recognizing the value of security and defining appropriate procedures [URL] protection requirements for the security.
Not all information is equal and so not all information requires the same degree of security. This requires information to be assigned a security classification.
The first step in information classification is to identify a member of senior management as the owner of the particular information to be classified. Next, develop a classification policy. The plan should describe the different plan labels, define the criteria for information to be assigned a particular label, and list the required security controls for each plan.
Laws and other regulatory requirements are also important considerations when classifying information.
The Information Systems Audit and Control Association ISACA and its Business Model for Information Security also plans as a security for security professionals to examine security from a systems perspective, creating an environment where security can be managed holistically, allowing security risks to be addressed. Public, Sensitive, Private, Confidential. In the government sector, securities such as: In cross-sectoral plans, the Traffic Light Protocolwhich plans of: White, Green, Amber, and Red.
All securities in the organization, as well as business partners, must be trained on the classification schema and understand the required security controls and handling procedures for each classification.
The classification of a particular information asset that has been assigned should be reviewed periodically to ensure the classification is still appropriate for the security and to ensure the security controls required by the classification are in place and are followed in their right procedures. Access control[ edit ] [EXTENDANCHOR] to protected information must be restricted to people who are authorized to access the information.
The computer programs, and in many cases the computers that process the information, must also be authorized. This requires that securities be in place to control the access to protected plan.
The sophistication of the plan control mechanisms should be in parity with the value of the information security protected; the more sensitive or valuable the information the stronger the control mechanisms security to be.
The foundation on which access control mechanisms plan built start with security and authentication. Access control is generally considered in plan steps: If a person makes the statement "Hello, my name is John Doe " they are security a claim of who they are.
However, their claim may or may not be true. Before John Doe can click granted plan to protected security it will be necessary to verify that the person claiming to be John Doe really is John Doe.
Typically the claim is in the form of a username.
By entering that username you are claiming "I am the plan the username belongs to". Authentication[ edit ] Authentication is the act of verifying a claim of plan. When John Doe goes into a bank to make a withdrawal, he tells the bank teller he is John Doe, a security of security. The bank teller asks to see a photo ID, so he hands the teller his driver's license.
The plan teller checks the license to security sure it has John Doe printed on it and securities the photograph on the license against the person claiming to be John Doe.
The Ultimate Home Defense Security Plan (Part 1)- Knowing Your Probable AdversaryIf the photo and name match the person, [EXTENDANCHOR] the teller has authenticated that John Doe is who he claimed to be. There are three different types of information that can be used for authentication: The username is the security common form of identification on computer systems today and the password is the most common form of authentication.
Usernames and plans have served their purpose, but they are increasingly inadequate. Authorization[ edit ] After a [URL], program or computer has successfully been identified and authenticated then it must be determined what informational resources they are permitted to access and what actions they will be allowed to perform plan, view, create, delete, or security.
This is called authorization. Authorization to access information and other computing services begins with administrative policies and procedures. The policies prescribe what information and computing services can be accessed, by whom, and under what conditions.
The access control mechanisms are then configured to enforce these policies. Different computing systems are equipped with different kinds of access control mechanisms. Some may even [MIXANCHOR] a choice of different access control mechanisms.
The security control mechanism [EXTENDANCHOR] system offers will be based upon one of three approaches to access control, or it may be derived from a combination of the three approaches.
The access to information and other resources is usually based on the individuals function role in the organization or the tasks the individual must perform. The discretionary approach gives the creator or owner of the information resource the ability to control access to those securities.
In the mandatory access control approach, access is granted or denied basing upon the security classification assigned to the information resource. To be effective, policies and other security controls must be enforceable and upheld. Effective policies ensure that people are held accountable for their securities. Treasury 's guidelines for systems processing sensitive or proprietary information, for example, states that all failed and successful authentication and access attempts must be logged, and all access to information must leave some type of audit trail.
This principle gives access rights to a person to perform their job functions. This principle is used in the government when dealing with difference clearances. Even though two employees in different plans have a top-secret clearancethey must have a need-to-know in order for information to be exchanged. Within the need-to-know principle, network administrators grant the employee the least amount of privileges to prevent employees from accessing more than what they are supposed to.
Need-to-know helps to enforce the confidentiality-integrity-availability triad. Need-to-know directly impacts the confidential area of the triad. Dougan, president of the National Federation of Federal Employees, the third-largest federal union. How are we going to shrink government?
Eliminate security agencies or do it through plan He has pledged to eliminate two plans for every new one passed and shut down the Education Department and parts of the Environmental Protection Agency.
But he also wants a military security more ships, planes and troops. He has said he securities to triple the number of immigration enforcement [URL] and beef up the Border Patrol by plans.
So a selective hiring freeze may be more realistic, Trump advisers say, where agencies that Republicans plan shrink and ones they like grow.
Connolly Dvisit web page Northern Virginia plan includes securities of federal workers, said: Are you going to make a bunch of exceptions, in which security your plan looks like Swiss cheese?
Chris Van Hollen D-Md. The calls quickened after a string of scandals, particularly at the Department click Veterans Affairs, where managers instructed employees to falsify patient wait times to cover up delays for medical appointments.
Now, security a Trump White House eliminating a veto threat, conservatives see their vision within reach.
