With the Internet acceding our sleeps in such an volatile mode, it was unavoidable that Internet security issues would follow also. While credit card frauds are an offline security problem that has been held over to the Internet as well, spamming and phishing are unambiguously Internet security hazards.
Spammers are an Internet phenomenon that have run big encouragement by the distribution of free scripts. Free scripts and free downloadable software are one of the biggest attracters of the web. Unluckily, they're also one of the greatest security risks the Internet proffers.
Spammers use free scripts to their reward very artlessly. Refer-a-Friend scripts are a great asset on any site. They allow visitors to commend a site to their friends. And, by simply a Refer-a-Friend script, a Webmaster can increase traffic on his website at 0 cost!
Regrettably, Refer-a-Friend scripts that don’t have inbuilt security features are a popular tool with spammers as well. When your site visitor enters friends’ e-mails, the insecure Refer-a-Friend scripts capture those e-mails and collates them into a Spam database.
The spammers then use the e-mails to create illegal lists and sell them for a profit or send large quantities of Spam. This can result in major damage for your website from loss of consumer loyalty and trust to deactivation of your e-mail privileges by your hosting company to even disbarment from your web server.
It thus becomes vital that any Refer-a-Friend script that you choose to install on your website must have a security feature. The scripts should limit how many people can be e-mailed at one time and how many e-mails can be sent within a limited period. It can also set a delay before the form can be used again. One of the most effective security features is to get visitors to enter a randomly generated visual code, which isn't clear by Spam software. Forewarned is forearmed.
