Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

How many world writeable files on your system? (Mandriva Linux msec)

Mandriva Linux includes a security tool called "msec" (configurable via "draksec").

One of the many things it regularily checks for is world writeable files.

If any are found, it writes the list to /var/log/security/writable.today.

"wc -l" simply counts the number of lines in the file.

This number should be low.

Browse through /var/log/security/writable.today and consider if any of those files *need* to be world-writeable (and if not, modify the permissions. eg: "chmod o-w $file").

A large number of world-writeable files may indicate that umask is not correctly set in /etc/profile (or ${HOME}/.bash_profile) but could also indicate poor security configuration or even malicious activity.

Know a better way?

If you can do better, submit your command here.

What others think

Similarly:

find / -xdev -type f -perm -o=w

-xdev prevents descending into other filesystems (your call).

-type f prevents listing symlinks, which are nominally, but not really, world-writable.

"msec" is run from crontab so the /var/log/security/writable.today file is there "already".

You don't have to wait for a find to work its way all through the entire filesystem.
