Why is passive information gathering considered safer compared to active information gathering?

Passive information gathering involves techniques that allow an individual to collect data without directly interacting with the target. This method is considered safer primarily because it minimizes the risk of detection. When data is gathered passively, the person conducting the assessment does not engage with the target systems or networks in a way that might alert the administrators or security personnel. This means that passive methods can often help a security technician glean important information without raising alarms, making it less likely for the target to respond or take action as a result of the information gathering.

Active information gathering, on the other hand, typically involves direct interaction with the target systems, such as port scans or probing for services, which can easily be detected by intrusion detection systems or firewalls. By reducing the footprint of the information gathering process, passive tactics not only enhance safety but also allow for a more stealthy collection of crucial intelligence that can inform further security assessments or penetration testing.

Other aspects of the question illustrate characteristics of information gathering but do not capture the fundamental safety benefit that comes from reduced risk of detection associated with passive methods.
