| Description |
|---|
| Local initialization files are used to configure the user's shell environment upon logon. Malicious modification of these files could compromise accounts upon logon. World-readable "dot files" such as .bash_history or .netrc can reveal plaintext credentials, such files should be further protected (e.g., 0600). |
| ℹ️ Check |
|---|
| Verify that all local initialization files have a mode of "0740" or less permissive with the following command: Note: The example will be for the "testuser" account, who has a home directory of "/home/testuser". $ find /home/testuser/.[^.]* -maxdepth 0 -perm -740 -exec stat -c "%a %n" {} \; | more 755 /home/testuser/.cache 755 /home/testuser/.mozilla If any local initialization files have a mode more permissive than "0740", this is a finding. |
| ✔️ Fix |
|---|
| Set the mode of the local initialization files to "0740" with the following command: Note: The example will be for the "testuser" account, who has a home directory of "/home/testuser". $ chmod 0740 /home/testuser/.<INIT_FILE> |
