RSA-768 is no longer secure

A quickie: You should probably go way beyond 1024 bits now that 768-bit RSA encryption is factorable. I would not recommend using encryption that is scheduled to be decrypted within the next 10 years.

Detecting when you've been hacked

Suppose your LINUX box is being targeted by a clumsy adversary that does not hide tracks very well. How do you detect it?

Put the following command in your login shell script, e.g /root/.bash_profile if your'e into Bash. It will report the root shell access to your email.

echo 'ALERT - Root Shell Access on:' `date` `who` | \
  mail -s "Alert: Root Access from `who | awk '{print $6}'`" YOUR_EMAIL_HERE
