Information
Unix-based systems support variable settings to control access to files. World-writable files are the least secure. See the chmod man page for more information.
Rationale:
Data in world-writable files can be read, modified, and potentially compromised by any user on the system. World-writable files may also indicate an incorrectly written script or program that could potentially be the cause of a larger compromise to the system's integrity.
Solution
Correct or justify any items discovered in the Audit step. Determine the existence of any 'write access' given for the 'other' category (chmod o-w <filename>), and work with the owner to determine the best course of action in accordance with site policy.
