Access Control
Access control serves as a pivotal component in information security, overseeing as well as regulating the authorization of entities to gain access to computing resources. It operates as a protective barrier, ensuring that only authorized persons or rather systems can interact with critical data, networks or even systems while hampering unauthorized entry (Kim & Solomon, 2010).
Single Sign-On (SSO)
Single Sign-On (SSO) streamlines the authentication process by enabling users to gain access to multiple applications with a single set of login credentials. This innovative approach eliminates the need for users to remember distinct usernames alongside passwords for ach system. Once authenticated, users gain seamless access to interconnected systems without the hassle of repeated logins.
Parts and Types of Access Control
- Discretionary Access Control (DAC):
Discretionary Access Control empowers users with control over their objects, granting them the authority to permit or rather restrict access to other entities. The resource owner holds the discretion to define access permissions (Hu et al., 2013).
- Mandatory Access Control (MAC):
Unlike DAC, Mandatory Access Control is centrally regulated and rigid, commonly implemented in government and military environments. Access permissions are determined by security labels and remain less susceptible to user alterations.
- Role-Based Access Control (RBAC):
Role-Based Access Control conforms to access with users’ roles within an organization. Users are assigned particular roles, each linked with predetermined permissions, simplifying the management of access.
- Attribute-Based Access Control (ABAC):
Attribute-Based Access Control factors in a number of attributes, such as user roles, time of day alongside location before granting access. This dynamic approach ensures context-aware access control.
- Rule-Based Access Control:
Rule-Based Access Control relies on predefined rules in order to make access decisions. These rules articulate the conditions under which access is either granted or denied, offering a structured framework for access management.
- Biometric Access Control:
Biometric Access Control incorporates unique biological traits, such as fingerprints or iris scans, for authentication purposes. This method fosters security by relying on distinct physical characteristics for identity verification.
Therefore, access control, with its diverse types, is indispensable for safeguarding critical information and maintaining the overall security posture of computing systems. Simultaneously, Single Sign-On fosters user convenience by simplifying the authentication process across a number of applications.
