Peter is surfing the internet looking for information about DX Company. Which hacking process is Peter doing?

Scanning involves actively probing a target's network or systems with tools like port scanners to discover live hosts and open services, which Peter is not doing.

Footprinting is the passive reconnaissance phase where an attacker collects publicly available data about a target such as company details, domain names, and personnel information from the internet without directly interacting with target systems. It is the precursor to active scanning and exploitation. Peter browsing the internet for information about DX Company matches this definition exactly.

Enumeration involves extracting detailed system-level information such as usernames, shares, and services through direct interaction with a target after initial contact is established, not passive internet browsing.

System hacking refers to actively exploiting discovered vulnerabilities to gain unauthorized access to systems, which is far beyond the passive internet research Peter is conducting.
