In Azure Security Center, what type of recommendations typically help in hardening security for virtual machines?

Access control recommendations in Azure Security Center focus on enhancing the security posture of virtual machines by ensuring that access is properly managed and restricted. These recommendations often include measures such as the implementation of role-based access control (RBAC), limiting administrative privileges, and ensuring that users have only the permissions necessary to perform their jobs.

By following access control recommendations, organizations can significantly reduce the risk of unauthorized access to virtual machines, thereby improving overall security.

While networking, identity, and data encryption recommendations are important, they serve different specific purposes. Networking recommendations typically address the configuration of network security groups and firewalls to protect against external threats. Identity recommendations tend to focus on ensuring that robust identity and access management practices are in place. Data encryption recommendations aim at safeguarding data at rest and in transit, but they do not directly address the management of user access or permissions for virtual machines. Thus, while all these areas contribute to an overarching security strategy, access control recommendations are specifically designed to enhance the security of access to the virtual machines themselves.
