Internet security: the importance of adding a CAPTCHA

Security is one of the most important aspects to consider when creating a blog or offering an online service through your website.
 
1.-The usefulness of CAPTCHA
If you want a person to validate themselves as a user on a website, post a comment on a blog entry, or fill out a form with personal data to purchase a service, it is necessary for all these actions to be protected with security mechanisms.
 
Among all the tools available to secure your website, we highlight CAPTCHA. It is essential because it prevents:
  • Spam comments on blogs.
  • Mass registrations on web services.
  • Attempts to manipulate survey results through automated voting.
  • Identity impersonation based on dictionary attacks that try thousands of passwords in just a few seconds.
 
 
2.-Machines vs humans
CAPTCHA is an English acronym that stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." It consists of having a person, and not a machine, type a series of characters displayed in a distorted format on the screen (as shown in the illustration), in such a way that only a human can interpret them. This ensures that it is a real person—and not a machine with malicious intent—trying to access your web services, preventing spam and malicious software.
 
 
CAPTCHAs have become an increasingly important technology in business and web services. They are designed to protect against attacks from "bots" (software programs that imitate human behavior) and to ensure the stability and continuity of services.
