Lots of bloggers and website administrators fail to recognize the importance of securing their site. I couldn’t imagine running a site that brought in some decent money a month and not taking a few minutes to secure it. From attacks like the hidden iFrame injection (Trojan virus) or even someone hacking the password and attempting to blackmail you, the work needed to fix these problems is much greater than the effort it takes to make sure it doesn’t happen to you.

Google takes it very seriously if your site is spreading malware content (which you will more than likely have no clue your site is even doing it) and will post an advisory to such sites in the search engine results. Visitors will see the message “This site may harm your computer” when trying to access your website/blog and by that time the damage is done. The cascading effect on the search engine rankings, resulting in low traffic and money. Advertisers may not show interest on your website.

Use the below link to see what Google thinks about your website (input your blog name instead of http://artfans.info).

Chap Secure Login

Download
HomePage
Whenever you try to login into your website, you can use this plugin to trasmit your password encrypted. The encryption process is done by the Chap protocol; this is particularly useful when you can’t use ssl or other kinds of secure protocols. By activating the ChapSecureLogin plugin, the only information transmitted unencrypted is the username; password is hided with a random number (nonce) generated by the session – and opportunely transformed by the md5 algorithm.

NoSpamNX

Download
HomePage
NoSpamNX automaticly adds additional formfields to your comment form, invisible to the users. If a spambot fills these fields blindly (which 99.9% of all spambots do), the comment will not be saved. You can decide if you want to block these spambots, mark them as spam or put them in moderation queue. Furthermore, you can put common spam-phrases on a blacklist.

Semisecure Login Reimagined

Download
HomePage
Semisecure Login Reimagined increases the security of the login process using an RSA public-key to encrypt the password on the client-side when a user logs in. The server side then decrypts the encrypted password with the private key. JavaScript is required to enable encryption. It is most useful for situations where SSL is not available, but the administrator wishes to have some additional security measures in place without sacrificing convenience.
