===Access to Stored Cryptographic Software and Cryptographic Programs===
When installing the NSS library files, the operator shall use the <code>chmod</code> utility to set the file mode bits of the NSS library files to '''0755''' so that all users can execute the NSS library files, but only the files' owner can modify (i.e., write, replace, and delete) the files. For example,
$ chmod 0755 libsoftokn3.so libfreebl3libfreebl*3.so
The file mode bits can be verified with the <code>ls</code> utility. For example,
$ ls -l libsoftokn3.so libfreebl3libfreebl*3.so
