I have been using Windows OS for a long time and there i needed to install a separate Anti virus Program (included with firewall, anti spam) etc..
With my mentor's recommendation, I have replaced Windows with Ubuntu12.10 64 bit. I really enjoyed the system. Its better than Windows OS.
I am a Java Developer, so I need to have Apache tomcat, JBoss and Glassfish installed along with MySQL. For my job requirement, I need to google for above Java Develoment and end up getting into many blogs.
I have searched for protecting Ubuntu, but they all end up with configuring the firewall. I really have no knowledge about how firewall needs to be configured according to my requirements. Do I also need to have an antivirus program on Ubuntu.
Can anybody guide me about how can I secure the Ubuntu 12.10 64bit System.
Your advice matters to me a lot.
