  2. Run the find / -path */proc -prune -o -nouser -print -o -nogroup -print command to verify that all the files in the vApp have an owner.
    All the files have an owner if there are no results.
  3. Run the find / -name "*" -type f -not -path "*/sys*" -not -path "*/proc*" -not -path "*/dev*" -perm -o+w | xargs ls -lb command to verify that none of the files are world writable files by reviewing permissions of all the files on the vApp.
    Others should not have write permission. The permissions on these files should be ##4 or ##5, where # equals the default given set of permissions for the Owner and Group, such as 6 or 7.
  4. Run the find / -path */proc -prune -o ! -user root -o -user admin -print command to verify that the files are owned by the correct user.
    All the files belong to either root or admin if there are no results.
  5. Run the find /usr/lib/vmware-casa/ -type f -perm -o=w command to ensure that files in the /usr/lib/vmware-casa/ directory are not world writable.
    There must be no results.
  6. Run the find /usr/lib/vmware-vcops/ -type f -perm -o=w command to ensure that files in the /usr/lib/vmware-vcops/ directory are not world writable.
    There must be no results.
  7. Run the find /usr/lib/vmware-vcopssuite/ -type f -perm -o=w command to ensure that files in the /usr/lib/vmware-vcopssuite/ directory are not world writable.
    There must be no results.
