In the Perimeter layer of the security model, you would typically secure items that control or facilitate network communication between the internal and external networks.
Based on the options presented, the items that would be secured in the Perimeter layer are firewalls and routers.
A) Routers: Routers are responsible for directing network traffic, determining the best path for data packets to travel, and facilitating communication between different networks. They play a crucial role in establishing the perimeter of a network and controlling inbound and outbound traffic. Therefore, securing routers is essential in ensuring the security of an organization’s network.
C) Firewalls: Firewalls act as a barrier between an internal network and the external internet. They enforce access control policies by examining network traffic and determining whether to allow or block specific communication. Firewalls can be either hardware or software-based and are typically installed at the network’s perimeter to protect internal assets from external threats. They are designed to filter and monitor both inbound and outbound traffic, providing an additional layer of security against unauthorized access and potential threats.
B) VLANs: Virtual Local Area Networks (VLANs) are a logical segmentation of a physical network into multiple smaller networks. They are created to improve network performance, manage network traffic, and provide logical separation between different groups or departments within an organization. While VLANs help control the flow of data within a network, they are not typically considered a part of the Perimeter layer. VLAN security is more focused on internal network segmentation, access control, and isolation of resources.
D) Switches: Switches are network devices that connect devices within a local network and enable the exchange of data between them. While switches play a crucial role in internal network connectivity, they are not directly associated with securing the network perimeter. Switches typically operate within the internal network and are responsible for forwarding traffic between connected devices.
In summary, the items that would typically be secured in the Perimeter layer of the security model are firewalls and routers. These components are vital in controlling traffic between the internal and external networks and protecting against unauthorized access and potential threats.
