Which of the following steps can be taken as countermeasures against sniffer attacks? Each correct answer represents a complete solution. Choose all that apply.
A.
Use encrypted protocols for all communications.
B.
Use switches instead of hubs since they switch communications, which means that information is delivered only to the predefined host.
C.
Use tools such as StackGuard and Immunix System to avoid attacks.
D.
Reduce the range of the network to avoid attacks into wireless networks.
A. Use encrypted protocols for all communications. Explanation: Encrypted protocols (e.g., SSL/TLS) are methods to encrypt communication content so that even if a third party intercepts the communication, they cannot understand the content.
B. Use switches instead of hubs since they switch communications, which means that information is delivered only to the predefined host. Explanation: Hubs send data to all devices, making them vulnerable to sniffer attacks. Switches, on the other hand, send data only to specific devices, thus enhancing security.
