The Blacklist

The Blacklist is a list used by organizations—such as governments, cybersecurity teams, or companies—to identify and exclude individuals, websites, or entities deemed untrustworthy, dangerous, or unapproved. It helps prevent unauthorized access, protect assets, or ensure safety by blocking or monitoring these flagged items or persons. Unlike a whitelist, which permits only approved entities, a blacklist actively restricts known risks. This system enhances security and risk management by systematically managing potential threats based on prior information or security policies.
