Directory services and protocols, including Lightweight Directory Access Protocol (LDAP) and Security Assertion Markup Language ( SAML), provide access controls for authenticating and authorizing users and entities and enabling them to connect to computer resources, such as distributed applications and web servers. These security controls work by identifying an individual or entity, verifying that the person or application is who or what it claims to be, and authorizing the access level and set of actions associated with the username or Internet Protocol (IP) address. After some high-profile breaches, technology vendors have shifted away from single sign-on ( SSO) systems to unified access management, which offers access controls for on-premises and cloud environments. Most organizations have infrastructure and procedures that limit access to networks, computer systems, applications, files and sensitive data, such as personally identifiable information (PII) and intellectual property.Īccess control systems are complex and can be challenging to manage in dynamic IT environments that involve on-premises systems and cloud services. Access control is a fundamental component of security compliance programs that ensures security technology and access control policies are in place to protect confidential information, such as customer data. The goal of access control is to minimize the security risk of unauthorized access to physical and logical systems. Multifactor authentication ( MFA), which requires two or more authentication factors, is often an important part of a layered defense to protect access control systems. Some of these systems incorporate access control panels to restrict entry to rooms and buildings, as well as alarms and lockdown capabilities, to prevent unauthorized access or operations.Īccess control systems perform identification authentication and authorization of users and entities by evaluating required login credentials that can include passwords, personal identification numbers (PINs), biometric scans, security tokens or other authentication factors. To secure a facility, organizations use electronic access control systems that rely on user credentials, access card readers, auditing and reports to track employee access to restricted business locations and proprietary areas, such as data centers. Logical access control limits connections to computer networks, system files and data. Physical access control limits access to campuses, buildings, rooms and physical IT assets. There are two types of access control: physical and logical. It is a fundamental concept in security that minimizes risk to the business or organization. Access control is a security technique that regulates who or what can view or use resources in a computing environment.
