try chmod 700 (i think) (owner RWX .group --- and public ---)
or Chmod 500 (i think) (owner RW- Group --- and public ---)
Chmod 600 (i think) (owner R-X Group --- public ---)

R= read
W = Write
X = execute
- = No permission.

700 = owner r / w / x
600 = owner r / w
500 = owner r / x
400 = owner r
200 = owner w
100 = owner x
