File protection using evaluation of file-specific values

An apparatus comprising:

• at least one processing device comprising a processor coupled to a memory;
• the at least one processing device being configured to implement the following steps:
• obtaining, by at least one entity associated with an operating system of at least one processing device, at least a portion of a file to be written to the at least one processing device;
• obtaining, by the at least one entity, at least one file-specific value associated with the at least a portion of the file;
• comparing, by the at least one entity, the at least one file-specific value to at least one value from a list of designated values;
• and
• initiating, by the at least one entity, at least one automated action based at least in part on a result of the comparison.

A non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device to perform the following steps:

• obtaining, by at least one entity associated with an operating system of at least one processing device, at least a portion of a file to be written to the at least one processing device;
• obtaining, by the at least one entity, at least one file-specific value associated with the at least a portion of the file;
• comparing, by the at least one entity, the at least one file-specific value to at least one value from a list of designated values;
• and
• initiating, by the at least one entity, at least one automated action based at least in part on a result of the comparison.
