Final answer:
Communication controls are preventive controls that help mitigate the risk of attacks in a network. These controls secure the communication channels within a network, ensuring data and information are protected from unauthorized access or manipulation. Examples of communication controls include encryption, firewalls, intrusion detection systems, and access control lists.
Step-by-step explanation:
Communication controls are preventive controls that help mitigate the risk of attacks in a network. These controls are designed to secure the communication channels within a network, ensuring that data and information are protected from unauthorized access or manipulation.
Example: One example of a communication control is the use of encryption. By encrypting the data being transmitted over the network, it becomes unreadable to anyone who does not have the decryption key. This prevents attackers from intercepting and understanding the data.
Other Communication Controls:
-
- Firewalls: Firewalls are network security devices that monitor and control incoming and outgoing network traffic. They can be configured to allow or block specific types of communication based on predefined rules.
-
- Intrusion Detection Systems (IDS): IDS are systems designed to detect and respond to unauthorized network activity. They monitor network traffic to identify any suspicious or malicious behavior and raise alerts or take action to prevent further damage.
-
- Access Control Lists (ACLs): ACLs are used to control access to network resources. They can be used to define who is allowed to communicate with specific network devices or access certain services.
