Which of the following are NOT a countermeasure to traffic analysis?
Click on the arrows to vote for the correct answer
A. B. C. D.Explanation.
Eavesdropping is not a countermeasure, it is a type of attack where you are collecting traffic and attempting to see what is being send between entities communicating with each other.
The following answers are incorrect: Padding Messages.
Is incorrect because it is considered a countermeasure you make messages uniform size, padding can be used to counter this kind of attack, in which decoy traffic is sent out over the network to disguise patterns and make it more difficult to uncover patterns.
Sending Noise.
Is incorrect because it is considered a countermeasure, tansmitting non-informational data elements to disguise real data.
Faraday Cage Is incorrect because it is a tool used to prevent emanation of electromagnetic waves.
It is a very effective tool to prevent traffic analysis.
Traffic analysis is a method used by attackers to analyze network traffic patterns to gather information about the source and destination of network traffic. The goal of traffic analysis is to uncover sensitive information, such as usernames, passwords, and other confidential data. To protect against traffic analysis, various countermeasures can be implemented.
Let's go through each answer option and determine if it is a countermeasure to traffic analysis or not:
A. Padding messages: Padding messages is a countermeasure to traffic analysis. Padding involves adding additional data to a message to make it the same length as other messages. This makes it difficult for attackers to identify specific messages in a stream of traffic. Therefore, option A is not the correct answer.
B. Eavesdropping: Eavesdropping is not a countermeasure to traffic analysis. Eavesdropping is the act of intercepting and listening to communication between two parties. It is a method used by attackers to gather information about the content of the communication, which is different from traffic analysis. Therefore, option B is the correct answer.
C. Sending noise: Sending noise is a countermeasure to traffic analysis. Sending noise involves sending a large amount of meaningless data to the network to make it difficult for attackers to identify and extract meaningful information. Therefore, option C is not the correct answer.
D. Faraday Cage: A Faraday Cage is a physical enclosure made of conductive material that blocks electromagnetic signals. It is not a countermeasure to traffic analysis, as it does not prevent attackers from analyzing network traffic patterns. Therefore, option D is the correct answer.
In conclusion, the correct answer is B. Eavesdropping, as it is not a countermeasure to traffic analysis.
