How To Protect Your Website From Spam Attacks

How To Protect Your Website From Spam Attacks

For anyone owning a website, the most restricting part is dealing with spam. Known as one of the most adversely hitting form of cyber attack, it can turn out to be a real nuisance for anyone having a website or email account. If you are one of those who believe that spam cannot do much damage, you are actually mistaken. It can cause the same level of damage as any other online threat. For any website or email account, it is important to overcome the spam attacks at the earliest.

 

Knowing Spam A Little Better

 

As per the spam.abuse.net’s definition, “Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services. Spam costs the sender very little to send – most of the costs are paid for by the recipient or the carriers rather than by the sender.” To sum up, one could say that spam is equivalent to that of the junk mail. These are however, responsible for causing large scale attacks.

 

Know How Your Website Is Susceptible To Spam?

 

Maximum spam attacks work while targeting the email addresses. Other than the email addresses, there are some entry points available over the website as well. These vulnerable entry points are the comments section and other forms that are available over the website.

 

What To Do When The Website Has Incurred Spam Attack?

 

The reason why spammers attack over your website is simple, they want to enter your server. Once they enter the server, they manage to send out new spam attacks to ‘n’ number of email addresses and websites. This action leads to blacklisting of the server that is hosting your website. As a result, none of the internet users will be able to find your website, nor would you be able to send or receive emails to anyone. With so much damage done to your website, you are forced to start from the scratch.

 

Top Two Techniques For Defending Against Spam

 

  1. The Honeypot Technique

 

Honeypot Technique is a savior when it comes to defending your website against spam. The best part is that it does the work quite efficiently without actually interfering with the user experience. For instance, you have an enquiry form that you want to get filled by numerous visitors. However, no one would ever like compromise the quality for quantity factor. Focusing merely on numbers would leave you with loads of spam bots offering you bogus content and ultimately entering your server.

With Honeypot Technique, you can filter the spam bots out without interrupting with the user experience. In this technique, an invisible field is added to the form. Humans would not be able to see the field so they would not be able to fill it out. However, the field would be visible to bots, which is why they would field it. This will alert the system and hence the submission would be treated as a spam.

 

 

  1. The Captcha Technique

 

Completely automated public Turing test i.e. Captcha is something that most of the  users are familiar with. These are basically the challenge texts that the user is asked to identify and fill. With almost all websites using captcha, as a user you must have come across them at some point while browsing. The captcha text is something that spam bots fail to read as these are deciphering images.

The only drawback is that when the text is deciphered to a great extend, it actually gets difficult for the user to guess the right captcha text. This usually leads to denial to access to the website. In most cases, captcha is seen over login tabs and the comment posting section. Guessing the captcha is something that the Spam bots fail at and hence they leave behind spam or junk, which is why they are denied access.
