In the trust model described, where trust between two organizations depends on the degree and quality of evidence provided by the first organization, the model in use is 'Validated Trust.' This model relies on the validation of evidence or credentials presented by one party to another to establish trust. The validation process assesses the credibility, reliability, and relevance of the information shared, forming the basis of the trust relationship between the sharing partners. This approach is common in threat intelligence sharing where the accuracy and reliability of shared information are critical.References:

During the threat modeling process, Mr. Andrews is in the stage of threat profiling and attribution, where he is collecting important information about the threat actor and characterizing the analytic behavior of the adversary. This stage involves understanding the technological details, goals, motives, and potential capabilities of the adversaries, which is essential for building effective countermeasures. Threat profiling and attribution help in creating a detailed picture of the adversary, contributing to a more focused and effective defense strategy.References:

When a corporate network's servers are sending huge amounts of traffic to a specific website, as detected by the network's Intrusion Prevention System (IPS), this behavior is indicative of a Botnet attack. A Botnet is a network of compromised computers, often referred to as "bots," that are controlled remotely by an attacker, typically without the knowledge of the owners of the computers. The attacker can command these bots to execute distributed denial-of-service (DDoS) attacks, send spam, or conduct other malicious activities. In this scenario, the servers behaving as bots and targeting a website with large volumes of traffic suggests that they have been co-opted into a Botnet to potentially perform a DDoS attack on the website abc.xyz.References:Incident Handler (CREST CPTIA) courses and study guides discuss various types of cyber threats and attack vectors, including Botnets and their role in distributed cyber attacks.
