I Used The Web For A Day On A 50 MB Budget10August,2020
Web development takes into account many security considerations, such as data entry error checking through forms, filtering output, and encryption. Malicious practices such as SQL injection can be executed by users with ill intent yet with only primitive knowledge of Web development as a whole. Scripts can be used to exploit Web sites by granting unauthorized access to malicious users that try to collect information.
Some of this is dependent on the server environment on which the scripting language, such as ASP, JSP, PHP, Python, Perl or Ruby is running, and therefore is not necessarily down to the Web developer themselves to maintain. However, stringent testing of Web applications before public release is encouraged to prevent such exploits from occurring. If some contact form is provided on a Web site it should include a captcha field in it which prevents computer programs from automatically filling forms and also mail spamming.
