If you have a security program and you do experience a loss that has legal consequences, your written program can be used as evidence that you were diligent in protecting your data and following industry best practices.

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. 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.

In the government sector, labels such as: This principle is a useful security tool, but it has never been successful at enforcing high assurance security on a system.

Least Privilege Need to Know [ edit ] Introduction The principle of least privilege, also known as the principle of minimal privilege or just least privilege, requires that in a particular abstraction layer of a computing environment every module such as a process, a user or a program on the basis of the layer we are considering must be able to access only such information and resources that are necessary to its legitimate purpose.

This principle is a useful security tool, but it has never been successful at enforcing high assurance security on a system. Authorization[ edit ] After a person, 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 run, view, create, delete, or change.

These focus on the organisational and cultural changes required to drive forward improvements. Unintentional corruption might be due to a software error that overwrites valid data.

When presented with six different information systems, each containing one-sixth of what they want, they generally rely on a piece of paper instead or ask the person next to them.

The four key elements in effective systems management

This usually results from the first two benefits, applications that install device drivers or require elevated security privileges typically have addition steps involved in their deployment, for example on Windows a solution with no device drivers can be run directly with no installation, while device drivers must be installed separately using the Windows installer service in order to grant the driver elevated privileges Mandatory Vacations[ edit ] Mandatory vacations of one to two weeks are used to audit and verify the work tasks and privileges of employees.

Partnering with ISSA International is a great opportunity to reach a targeted audience of information security professionals. Our members value your support and educational contributions in advancing the information security community. Executive Summary Executive Summary The challenges of implementing an effective information security program are broad and diverse.

To address these challenges the Information Systems Audit and. Human factors play a significant role for information security. In particular, human characteristics behaviour impacts information security and ultimately associated risks.

This article provides an overview of our research for analysing the human factors and their influence for an effective information security management system. Having a security program means that you’ve taken steps to mitigate the risk of losing data in any one of a variety of ways, and have defined a life cycle for managing the security of information and technology within your organization.

Informed information security decisions will be made based on risk assessment to implement technical, management, administrative and operational controls, which is the most cost effective.
