Differentiate between active and passive attack.

Comparison Basis	Active Attack	Passive Attack
Task Performed	Attempts to change system resources or affect operation	Attempts to read or make use of information from the system
Emphasis is on	Causing direct harm to the system	Observing and obtaining information without causing harm
Occurrence	Occurs when an unauthorized party actively modifies data or disrupts resources	Does not actively disrupt or modify data; focuses on monitoring and extracting information
Damage to System	Always causes damage to the system (integrity and availability)	Does not cause immediate damage; primarily poses a threat to confidentiality
Attack Awareness	The entity (victim) is generally informed about the active attack as it directly impacts the system’s operation	The entity (victim) may be unaware of a passive attack since it does not directly impact the system’s operation
Detection	Active attacks are usually easier to detect as they involve noticeable changes to the system.	Passive attacks can be challenging to detect as they involve eavesdropping or monitoring without making noticeable changes to the system.
