Notes

Takes into account many security considerations, such as data entry error checking via forms, filtered output, and encrypted web development. A bad user can perform malicious behavior such as SQL injection without having only basic knowledge of network development as a whole. Exploit scripts can be granted unauthorized access to malicious users in an attempt to collect information such as email addresses, passwords and protected content such as credit card numbers.

This part is dependent on the server environment (most commonly Apache and Microsoft's IIS) to run scripting languages ??such as PHP, Ruby, Python, Perl or ASP, and therefore is not necessarily used by web developers. to maintain. If some contact form is offered on a website, it should include a verification code field that prevents computer programs from filling out the form and spamming emails.

Keeping a web server secure from intrusions is often called: server port hardening. Many technologies are required to keep information playing safe on the Internet as it is transmitted from one place to another. For example, Secure Sockets Layer (SSL) encryption certificates are issued by certificate authorities to help prevent online fraud. Many developers often use different forms of encryption to transmit and store sensitive information when developing. A basic understanding of information technology security issues is often part of a web developer's knowledge.
