Network Layer Security Measures

B.

Trust zones can be implemented to separate systems or tiers along logical lines for great security and access controls.

Each zone can then have its own security controls and monitoring based on its particular needs.

In a traditional data center, security measures are implemented at different layers of the network stack to protect the infrastructure and data from unauthorized access and breaches. When it comes to cloud environments, the same principles apply, and security measures need to be implemented to ensure that data and applications are protected.

Out of the options given, the security measures that are applicable to a cloud environment are:

B. Trust zones: In a traditional data center, trust zones are used to segment the network into logical zones to control access to sensitive data and applications. Similarly, in a cloud environment, trust zones can be implemented to ensure that data is only accessible to authorized users and applications. Trust zones can be implemented using virtual private clouds (VPCs), which are isolated networks within the cloud environment that can be customized to meet specific security and compliance requirements.

C. Redundant network circuits: In a traditional data center, redundant network circuits are used to ensure high availability and minimize downtime in the event of a network failure. In a cloud environment, redundant network circuits can be implemented to ensure that data and applications are always accessible, even in the event of a network outage. This can be achieved using multiple availability zones (AZs), which are geographically separate data centers that provide redundancy and high availability.

D. Direct connections: In a traditional data center, direct connections can be used to establish a dedicated link between two points, providing high-speed and secure connectivity. In a cloud environment, direct connections can be used to establish a secure and dedicated link between on-premise infrastructure and the cloud environment. This can be achieved using a virtual private network ( VPN) or a direct connect service provided by the cloud provider.

A. Dedicated switches: While dedicated switches can be used in a traditional data center to provide high-speed and secure connectivity, they are less applicable in a cloud environment. This is because cloud environments typically rely on software-defined networking (SDN) and virtualization technologies, which provide a flexible and scalable network infrastructure that can be easily managed and customized. In a cloud environment, network switches are virtual and provided by the cloud provider, and there is no need to purchase and manage physical switches.

In summary, trust zones, redundant network circuits, and direct connections are security measures that are applicable to both traditional data centers and cloud environments. While dedicated switches are also used in traditional data centers, they are less applicable in a cloud environment due to the flexible and scalable nature of the network infrastructure provided by the cloud provider.
