Which of the following involves blocking or limiting access to resources like files, folders, or write access from specific accounts?

The focus on blocking or limiting access to resources such as files, folders, or write access from specific accounts aligns perfectly with the role of Access Control Lists (ACLs). ACLs are used within file systems and network configurations to define who can access specific resources and what actions they can perform.

For instance, an ACL may specify that certain users can read a file but cannot modify or delete it, whereas others may not have any access at all. This precise control helps safeguard sensitive information and ensures that users only interact with data and applications as intended, conforming to the principle of least privilege.

The other options relate to different aspects of cybersecurity. Update processes are primarily concerned with keeping software current and protected from vulnerabilities. Firewall rules focus on controlling traffic between networks by allowing or blocking data packets based on set criteria. Endpoint protection centers on safeguarding devices from malware and other threats but does not specifically manage access to files or resources. Thus, the role of ACLs is distinct and pivotal for managing resource access effectively.
