Cross site scripting is a programming issue that requires significant experience in computer programming. Various tutorials are available online on programming websites.
Two methods to prevent cross site scripting that come to mind. One is to encode and decode the input field values of your HTML form. This will change the special characters of the code a hacker tries to place into your form fields to do cross site scripting. The other is to be sure and validate the input types of your form fields so that only valid data types are accepted. Hope this helps.
Securing PHP web applications against common vulnerabilities is crucial for protecting sensitive data and maintaining user trust. Here are some best practices for securing PHP web applications against SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF)
In short: Yes, a cross-site scripting attack (XSS) can be used to access cookies. This is a big part of the reason why you shouldn't rely solely on cookies to identify a user. In 2006, LiveJournal was a victim of just this style of attack. You can read about it in detail in the related links. Since then, browsers have implemented security measures making this kind of attack far more difficult to implement (but not impossible.)
Cross-Site Scripting attack. (XSS)
"XS" typically stands for "extra small," a clothing size designation that indicates a smaller fit compared to standard sizes. It is often used in fashion and apparel to cater to individuals who require smaller garments. Additionally, "xs" can also refer to "cross-site," as in cross-site scripting (XSS) in web development, but in the context of sizing, it predominantly means extra small.
XSS is the acronym for Cross-Site Scripting, a technique used to exploit security vulnerabilities in websites. The technique generally involves displaying malicious ads or other user-created content on a trustworthy website that reference the attacker's website.
W3 Schools (w3schools.com) is a great site. They have extensive information and tutorials for many scripting languages. Codecademy (codecademy.com) is another great site which is based more on learning through experience rather than including information in encyclopedic form, though it focuses more on the programs essential to web programming, such as HTML, CSS, and JavaScript. Apparently Microsoft also has a website dedicated to scripting, at technet.microsoft.com, but I have never used their site.
PHP is a scripting language used for web servers and application development. PHP hosting is a web hosting service that allows for more complex site because is supports the PHP scripting language.
What site to learn LUA on is Dependant of what you are scripting on. If you are on a game, then go to that game's wiki to learn LUA. Try searching Google for LUA lessons depending on what your purpose is.
