I have a classifieds website, which uses php5 and mysql, and also java (solr).
I am new to linux and VPS...
I have installed SSH, and I have installed IPtables, and also I have PuTTY which I use as a terminal. Also, Filezilla is installed on my computer, and whenever I connect to my VPS, the "host" field in Filezilla says "Sftp://ip-adress" so I am guessing it is a safe connection.
I used this command to find out if I had SSHD installed:
and it returned some places where it actually was installed. So I havent actually installed it.
Now, my Q is, is this enough?
What other security measures should I take?
Any good articles about security and how to set it up on a VPS?
Remember, I have a windows xp OS on my laptop, but the OS for my VPS is Ubuntu 9.10.
Also, I have apache2 installed...
