Access control is a fundamental component of data security that dictates who’s allowed to access and use company information and resources. Through authentication and authorization, access control policies make sure users are who they say they are and that they have appropriate access to company data. Access control can also be applied to limit physical access to campuses, buildings, rooms, and datacenters.

Access control identifies users by verifying various login credentials, which can include usernames and passwords, PINs, biometric scans, and security tokens. Many access control systems also include multifactor authentication (MFA), a method that requires multiple authentication methods to verify a user’s identity.
Once a user is authenticated, access control then authorizes the appropriate level of access and allowed actions associated with that user’s credentials and IP address.
There are four main types of access control. Organizations typically choose the method that makes the most sense based on their unique security and compliance requirements. The four access control models are:
Access control keeps confidential information such as customer data, personally identifiable information, and intellectual property from falling into the wrong hands. It’s a key component of the modern zero trust security framework, which uses various mechanisms to continuously verify access to the company network. Without robust access control policies, organizations risk data leakage from both internal and external sources.
Access control is particularly important for organizations with hybrid cloud and multi-cloud cloud environments, where resources, apps, and data reside both on premises and in the cloud. Access control can provide these environments with more robust access security beyond single sign-on (SSO), and prevent unauthorized access from unmanaged and BYO devices.

As organizations adopt hybrid work models, and as business apps move to the cloud, it’s important to protect against modern-day threats coming from the internet, usage of BYOD and unmanaged devices, and attacks looking to exploit apps and APIs. Citrix secure access solutions ensure applications are continually protected, no matter where people work or what devices they use.
