In a Nutshell
Protect Your Websites, Protect Your Visitors & Protect Yourself….
Remember, just protecting 1 site will not work if you have multiple sites on the same account. Hackers need just 1 access point. If they gain access to even one of your websites that sit in your shared hosting account, they may easily attack your other websites. Hence if you have 5 websites on a single server, you should make sure you have a Firewall for each of them. It is also important to scan the server for software versions as well as known vulnerabilities.
Also, remember that more websites you have sitting on your server, the more susceptible you will be to malicious activity. Hence clean your garage to stay away from malicious activities.
