A "drum lock" is a device that secures the bung flange of a drum to prevent unauthorized access to its contents, while a "barrel lock" refers to a type of cylinder lock where the barrel is the part that turns with the key to operate the locking mechanism. Drum locks prevent theft and sabotage of drum contents by creating an anti-tampering seal, and barrel locks are components of many types of security systems, with the key activating the internal mechanism.
