This type of analysis is deterministic because it assigns fixed values to the scenario and calculates the expected outcomes based on those values. Deterministic analysis does not account for uncertainty or randomness in the scenario. References: (Module 3, Lesson 3.1.2)

 Availability is one of the three pillars of the CIA triad, a model that defines the principles of information security. Availability describes the concept of data consistently and readily being accessible for legitimate users. Availability ensures that the network and systems are operational and resilient to disruptions, such as denial-of-service attacks, hardware failures, or natural disasters. Availability also involves maintaining backup and recovery procedures, load balancing, and redundancy mechanisms. References:

In the context of the cyber kill chain model, spam campaigns fall under the “delivery” phase where attackers deliver malicious payloads via email or other means to target systems or networks. References: Cisco Cybersecurity Operations Fundamentals, Module 1: Security Concepts, Lesson 1.4: Security Monitoring, Topic 1.4.2: The Cyber Kill Chain Model

Untampered images are crucial for security investigations as they provide original evidence that has not been altered or corrupted; their integrity and authenticity can be verified by comparing the stored hash and the computed hash of the image. If they match, the image is untampered and can be used for analysis. Tampered images, on the other hand, are useless for security investigations as they may contain false or misleading information; their integrity and authenticity are compromised by the modification of the image data. Tampered images may be used for incident recovery purposes, such as restoring a system to a previous state, but not for forensic purposes. References := Cisco Cybersecurity Operations Fundamentals - Module 6: Security Incident Investigations
