Root Access Notification:
This will inform you each time access is made to the root account:
In SSH:
Code:
cd /root
edit .bashrc and add the following at the end, for freebsd: edit .cshrc
Code:
echo -e “root access on `date`” ‘\n’ `who` | mail -s “Root Alert!” you@youremail.com
Disabling Compilers
When the compiler is disabled, the hacker is not able to compile and make the exploit. This step will prevent “The ability to compile the file in the system”. Most of the hacking guides that is found in the net suggest of compiling the exploit in the system, and seldom a pre-compiled binary is distributed. Thus, either via shell access or daemon exploit or via cgi/php abuse, they will try to get hold of your compiler and compile the exploit. Normally, your users do not need access to the compiler, so it is safe to restrict/disable compilers
Why should ports be secured ?
Open ports are via which a hacker determines what daemons your server is running, and whether or not, your system can be exploited or not. Port scan is the first thing that is done to fingerprint your OS and determine what is running. Open ports behave like open windows in your house. The more closed and armoured windows you have, the less thempting to thieves. Open ports in the server work in the same way, the more they are, the more tempting they become.
Choosing a webhost:
You have written your first (or 101st) website, you want the whole world to see it and you want it quick. Stop for a second and take a look at what you are wanting. From 10p to £1000 a month there is a lot of choice. Most people tend to be swayed toward one webhost by someone else that has used them; do they look for the same things in a webhost as you?
Why should I secure services ?
When your server is not running any unnecessary daemon, and all those running up2date, it will divert the hacker out from your system. To the hacker, it is saying “nothing of intrest here buddy!, no extra daemons to hack, and those daemons that are there, are all updated. Better luck elsewhere”
Perhaps you have bought a new domain name or need to change a filename without losing links which are pointing to it or maybe you have just changed the structure of your website. Regardless, your search engine rankings could take a real hit unless you make sure that people can still find your pages.
There are a couple of ways to achieve a redirect. Some are good and some are not so good, here we try to make some sense of it for you.
