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.
