Isaca Exam Cybersecurity-Audit-Certificate Topic 1 Question 7 Discussion

The MOST cost-effective technique for implementing network security for human resources (HR) desktops and internal laptop users in an organization is using avirtual local area network (VLAN). A VLAN is a logical grouping of network devices that share the same broadcast domain regardless of their physical location or connection. A VLAN can enhance network security by isolating different types of traffic or users from each other and applying different security policies or rules based on the VLAN membership. For example, an organization can create a VLAN for HR desktops and internal laptop users that restricts their access to only HR-related systems or resources. A VLAN can also reduce network costs by saving bandwidth, improving performance, and simplifying management.
