Final answer:
Maja should consider a DDoS Prevention System (DPS) and possibly a DNS sinkhole as part of her investigation into DDoS mitigations. These systems help protect network infrastructure by identifying and redirecting malicious traffic.
Step-by-step explanation:
If Maja has been asked to investigate DDoS mitigations, she should consider a DDoS Prevention System (DPS). A DDoS Prevention System is a security solution specifically designed to identify and mitigate Distributed Denial of Service (DDoS) attacks. Unlike a MAC pit or an IP denier, which are not standard terms or technologies used in the context of DDoS mitigation, a DPS employs various techniques to protect network infrastructure. One common mitigation technique is traffic analysis, which can differentiate legitimate user traffic from attack traffic. Another effective measure is a DNS sinkhole, which can redirect malicious traffic away from its intended target to a 'dead end' or a controlled environment.
