Hello, I would like to know how you can build your Blog or Site Security ? -- If you Run a Big Blog or Site then how you can build your site's security From Hackers OR From Enemies ? Please share your tips or advice...
That really depends. In your scenario do you have root access to your server or is this a shared webhost?
Make sure your server is also secured. You can fix a lot of security holes with just CSF firewall alone.
1) If you use a popular CMS or web app make sure you always update when a patch or update is released. 2) chmod folders to 744 and files to 644 3) limit access to the admin areas and ftp to just yourself or a trusted few 4) nothing is ever secure. if someone on the same shared hosting server as you are, and if they have shitty scripts installed that allow for say RFI's - a hacker can easily escalate their permissions to control the entire server and essentially take you down. 5) check to see if your host has mod_security installed or something similar 6) check for DoS / firewall management. a webhost who doesnt know how to configure port switches can kill off a site themselves during an attack or even high server load 7) backup daily
There are a lot of ways to attack you or your website. 1. Hacking your server. 2. Hacking your platform/CMS. 3. Putting a link from paid-to-click sites to your site to destroy your image to search engines. (this may require a little investment, though, say around $20) 4. Putting a link from porn sites to your website. 5. Spamming other people and sending them to your site to eventually destroy your site's credibility. 6. Click bombing your Adsense. This will get you banned from Adsense. If you are running a website avoid making enemies with other webmasters as you cannot probably benefit from it. Instead, befriend anyone. Also, if you have writers, treat them well. Google has become so strict about the credibility of the sites. It's a good thing your authors have good reputation on the web.
