CPTIA Exam Dumps : CREST Practitioner Threat Intelligence Analyst

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:

A negligent insider is an individual within an organization who, due to a lack of knowledge on security threats or in an attempt to increase workplace efficiency, inadvertently bypasses security procedures or makes errors that compromise security. This type of insider threat is not malicious in intent; rather, it stems from carelessness, oversight, or a lack of proper security training. Such insiders might click on phishing links, mishandle sensitive information, or use unsecured networks for work-related tasks, thereby exposing the organization to potential security breaches. This contrasts with compromised insiders (who are manipulated by external parties), professional insiders (who misuse their access for personal gain), and malicious insiders (who intentionally aim to harm the organization).References:The Incident Handler (CREST CPTIA) courses and study guides discuss different types of insider threats, emphasizing the importance of security awareness training to mitigate the risks associated with negligent insiders.

Incapsula is a cloud-based application delivery platform that offers a comprehensive security solution, including protection against Distributed Denial of Service (DDoS) attacks. By providing DDoS mitigation services, Incapsula helps protect websites and online services from being overwhelmed by traffic intended to make the resource unavailable to its intended users. The platform filters out malicious traffic and allows legitimate traffic through, thus ensuring that the organization's online resources remain available even under attack.

References:The CREST CPTIA curriculum includes discussions on various tools and strategies for protecting organizations against DoS/DDoS attacks, highlighting the importance of incorporating services like Incapsula into an organization's cybersecurity defenses to mitigate the risk and impact of such attacks.
