Which of the following are the three broad categories of cybersecurity investigations?

The three broad categories are public investigations (initiated by government or law enforcement agencies with legal authority), private investigations (conducted by organizations or hired firms internally), and individual investigations (conducted by or on behalf of a single person). This framework reflects the distinct legal standing, scope, and methodology applicable to each category.

Judiciary is not a primary investigation category - judicial involvement may arise across investigation types but does not define a standalone category.

Corporate is a narrower sub-label within private investigations; treating it as a separate top-level category creates an inaccurate and redundant taxonomy.

Government and corporate are more specific sub-labels; the accepted broad categorization uses public, private, and individual rather than government, corporate, and private.
