## INSECURE (WORLD-WRITABLE) DIRECTORIES
 
# World-writable directories will allow file writing by any user on the machine. 
# These directories can be mass-scanned so this attack has been surfacing quickly. 
# Even after you've checked all the above options this step must be performed. 
# Even if you're sure you didn't make any permission mistakes, some less security-aware 
# software vendors or plugin developers often use system commands or language-native 
# permission-management functions to make some directories (usually ones used for caching 
# and temporary files, session files etc) to ease installation and management.

# To scan for directories with world-writeable permissions use the UNIX find tool.
# If no results are displayed, then no folders are world-writeable.

alias dir777="find . -type d -perm -o=w;"

# FIXING WORLD-WRITABLE DIRECTORIES
#
# You can mass-change all your world-writable directories permission with the UINX find tool
alias dir777fix="find . -type d -perm -o=w -print -exec chmod 755 {} \;"

# find . -type d -perm -o=w -print -exec chmod 770 {} \;

# It's always better to enumerate all the world-writable directories and then 
# deciding the proper permissions. Some folders require special attention.
