There are more things than we know that can be revealed by your JPEG EXIF metadata such as the type of camera you use, aperture settings, the type of focus, lens type and even the location of the picture taken that might compromise the privacy of the persons or locations depicted in the photograph.
One of the things that we can do to is to strip away the information from JPEG files before uploading them to the internet, by using exiftool or jhead.
Exiftool
Install libimage-exiftool-perl
sudo apt-get install libimage-exiftool-perl
and by running the command
exiftool -all= *.jpg
jhead
Install jhead package:
sudo apt-get install jhead
and by running the command
jhead -purejpg /path/to/*.jpg

One of the factor that makes your system easily crackable is the weak password. PAM cracklib forces users to choose stronger password by analyzing the password strength, length and entropy.
To enable pam_cracklib in Debian / Ubuntu operating system, you need to install libpam_cracklib:
sudo apt-get install libpam_cracklib
Then edit the “/etc/pam.d/common-password” file using your favorite editor. Then, add and uncomment the following line at the end of the file.
password required pam_cracklib.so retry=3 minlen=6 difok=3
difok determines the number of same characters that allowed to be present in the old and new passwords.
