Information security

A key that is weak or too short will produce weak encryption. The value of an organization lies within its information -- its security is critical for business operations, as well as retaining credibility and earning the trust of clients.

Cryptography can introduce security problems when it is not implemented correctly. Information that has been encrypted rendered unusable can be transformed back into its original usable form by an authorized user who possesses the cryptographic keythrough the process of decryption.

Acts of nature, acts of war, accidents, malicious acts originating from inside or outside the organization.

Some may even offer a choice of different access control mechanisms. DoCRA helps evaluate safeguards if they are appropriate in protecting others from harm while presenting a reasonable burden. Cryptography Information security uses cryptography to transform usable information into a form that renders it unusable by anyone other than an authorized user; this process is called encryption.

Information security infosec is a set of strategies for managing the processes, tools and policies necessary to prevent, detect, document and counter threats to digital and non-digital information. Controls can vary in nature, but fundamentally they are ways of protecting the confidentiality, integrity or availability of information.

Need-to-know helps to enforce the confidentiality-integrity-availability triad. Logical and physical controls are manifestations of administrative controls, which are of paramount importance.

Physical[ edit ] Physical controls monitor and control the environment of the work place and computing facilities.

To fully protect the information during its lifetime, each component of the information processing system must have its own protection mechanisms. Managing information security amid new threats: This should allow them to contain and limit the damage, remove the cause and apply updated defense controls.

Or, leadership may choose to mitigate the risk by selecting and implementing appropriate control measures to reduce the risk. The policy should describe the different classification labels, define the criteria for information to be assigned a particular label, and list the required security controls for each classification.

If a person makes the statement "Hello, my name is John Doe " they are making a claim of who they are. The access control mechanism a system offers will be based upon one of three approaches to access control, or it may be derived from a combination of Information security three approaches.

Access control is generally considered in three steps: In recent years these terms have found their way into the fields of computing and information security.Keep up to date with the latest Information Security and IT Security News & Articles - Infosecurity Magazine.
