As suggested by Zomaya (2021), some of the best practices for web form
security include using encryption, validating user input, securing file uploads,
employing verification tools like reCAPTCHA, keeping your error messages
purposefully vague, and the ever-important task of applying security updates
and patches as soon as they are released. Encrypting web form data traffic
from end-to-end using HTTPS and SSL certificates helps to prevent man in
the middle attacks. Validating and sanitizing user input helps to prevent SQL
injection attacks by ensuring that the web form only accepts expected forms
of data. Any web form that will accept a file upload presents a hacker with
an opportunity to upload malicious scripts or software to your system. That’s
why it’s always important to “restrict allowed file types, validate files users
upload, set site size limits, only allow authenticated users to upload files,
change file names after upload, [and] isolate uploaded files” (Zomaya,
2021). reCAPTCHA isn’t necessarily a full-proof verification tool, however, it
will help slow down attackers and make your web form a little less ideal of a
target. Similarly, keeping error messages purposefully vague can also slow
down attackers. If they’ve created a likely list of usernames and passwords
to try out on your site, returning the error message “password is incorrect”
lets a hacker know they’ve discovered a real user account and now just need
to find the correct password for that account to gain site access. It’s
important to return a vaguer message such as “invalid username and/or
password,” so attackers don’t gain any useful information from the error
message. And lastly, as in all areas of cybersecurity, it is imperative to
consistently check for and install patches and updates as soon as they are
released to address any potential vulnerabilities in your site.
