Security controls or security measures are safeguards or countermeasures to avoid, detect, counteract, or minimize security risks to physical property, information, computer systems, or other assets. [1] In the field of information security, such controls protect the confidentiality, integrity and availability of information.
The use of information security risk analysis to drive the selection and implementation of information security controls is an important feature of the ISO/IEC 27000-series standards: it means that the generic good practice advice in this standard gets tailored to the specific context of each user organization, rather than being applied by rote ...
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [ 1 ]
Logical security consists of software [1] safeguards for an organization's systems, including user identification and password access, authenticating, access rights and authority levels. These measures are to ensure that only authorized users are able to perform actions or access information in a network or a workstation.
Data security typically goes one step further than database security and applies control directly to the data element. This is often referred to as data-centric security. On traditional relational databases, ABAC policies can control access to data at the table, column, field, cell and sub-cell using logical controls with filtering conditions ...
Role-based access control is a policy-neutral access control mechanism defined around roles and privileges. The components of RBAC such as role-permissions, user-role and role-role relationships make it simple to perform user assignments. A study by NIST has demonstrated that RBAC addresses many needs of commercial and government organizations. [4]
The following design principles are laid out in the paper: Economy of mechanism: Keep the design as simple and small as possible. Fail-safe defaults: Base access decisions on permission rather than exclusion. Complete mediation: Every access to every object must be checked for authority. Open design: The design should not be secret.
ISO/IEC 27001 is an international standard to manage information security.The standard was originally published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) in 2005, [1] revised in 2013, [2] and again most recently in 2022.
