CREST CPTIA Dumps Questions Answers

The data preprocessing step performed by Johnson, where he analyzes user activities within a certain time period to create time-ordered domain sequences for further analysis on sequential patterns, is known as user-specific sessionization. This process involves aggregating all user activities and requests into discrete sessions based on the individual user, allowing for a coherent analysis of user behavior over time. This is critical for identifying patterns that may indicate a watering hole attack, where attackers compromise a site frequently visited by the target group to distribute malware. User-specific sessionization helps in isolating and examining sequences of actions taken by users, making it easier to detect anomalies or patterns indicative of such an attack.References:The CREST materials discuss various data preprocessing techniques used in the analysis of cyber attacks, including the concept of sessionization to better understand user behavior and detect threats.

Incident triage is the phase in the Incident Handling and Response (IH&R) process where identified security incidents are analyzed, validated, categorized, and prioritized. This step is crucial for determining the severity of incidents and deciding on the order in which they should be addressed. During triage, incident handlers assess the impact, urgency, and potential harm of an incident to prioritize their response efforts effectively. This ensures that resources are allocated efficiently, and the most critical incidents are handled first. Incident recording and assignment involve logging incidents and assigning them to handlers, containment focuses on limiting the extent of damage, and notification involves informing stakeholders about the incident.References:The Incident Handler (CREST CPTIA) courses and study guides detail the IH&R process, emphasizing the importance of triage in managing and responding to security incidents effectively.

James's activities, including creating anonymous access to cloud services to carry out attacks such as password and key cracking, hosting malicious data, and conducting DDoS attacks, exemplify the abuse and nefarious use of cloud services. This threat involves exploiting cloud computing resources to conduct malicious activities, which can impact the cloud service provider as well as other users of the cloud services. This abuse ranges from using the cloud platform's resources for computationally intensive tasks like cracking passwords or encryption keys to conducting DDoS attacks that can disrupt services for legitimate users.References:The Incident Handler (CREST CPTIA) certification emphasizes understanding cloud-specific security challenges, including the abuse of cloud services, and recommends strategies for mitigating such risks, highlighting the need for comprehensive security measures to protect cloud environments.
