Final answer:
In response to a DoS attack, high traffic can be defensively treated in ways including being rerouted to other networks, absorbed by robust systems, or ignored if identified as malicious. Encryption is not typically a method for managing traffic volume during such attacks.
Step-by-step explanation:
In the context of DoS attack defenses, when faced with high traffic that could potentially be a part of a denial of service attack, defense mechanisms vary. These defense strategies include:
Rerouted: Traffic may be redirected to other servers or networks to distribute the load. This is often implemented as a part of a larger network's load balancing strategy.
Ignored: Traffic identified as malicious can sometimes be ignored or dropped, but this is not always effective if the volume is too high or if the traffic is hard to distinguish from legitimate requests.
Absorbed: Utilizing robust network infrastructure that can handle massive amounts of traffic, or services designed to absorb and analyze high volumes of network traffic, can be an effective way to mitigate the effects of a DoS attack.
Encrypted: While encryption is a vital part of securing communications, encrypting traffic is not a direct method for dealing with high volumes of traffic in a DoS attack; it's more about securing the contents.
The defenses against DoS attacks are critical for maintaining the integrity of internet services and ensuring that system resources remain available to legitimate users.
