Organizations may add an extra layer of protection by implementing a Cloud Access Security Broker (CASB) between their users and the cloud services they access. Through the use of policies, activity monitoring, and data protection, it is meant to ensure the safety and legitimacy of using cloud-based services.
Users’ communications with cloud services are intercepted by CASBs, which then utilise such communications to enforce security policies. Their flexibility in deployment options includes on-premises, cloud, and hybrid settings. Firewalls, intrusion detection systems, and data loss prevention (DLP) solutions are just some of the security measures that may be used with a CASB.
It’s common for CASBs to offer a wide range of security features, including:
- Access and security policy management (ASM): CASBs may monitor and regulate access to cloud services based on user roles and rules, in addition to providing authentication and permission for users accessing cloud services.
- Protection of sensitive information: CASBs may encrypt data at rest and in transit, as well as categorise it by risk and apply appropriate safeguards.
- Security against threats: CASBs can identify and block malicious traffic before it reaches cloud services, protecting them from things like malware, phishing, and even advanced persistent threats (APTs).
- The General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA) are two examples of requirements that CASBs may assist businesses in meeting.
- Control and monitoring: CASBs let you keep tabs on how cloud services are being utilised, and they may even let you establish and enact policies for them.
