This tag is for Joomla-related security questions, and extension/template coding in order to prevent intrusion.
Web sites are unfortunately prone to security risks. Hackers either seek to compromise the corporate network or the end-users accessing the website by subjecting them to drive-by downloading.
As a result, industry is paying increased attention to the security of the web applications themselves in addition to the security of the underlying computer network and operating systems.
The majority of web application attacks occur through cross-site scripting (XSS) and SQL injection attacks which typically result from flawed coding, and failure to sanitize input to and output from the web application.
Internet security is a vast and fast-moving topic. No one set of rules can cover all the possible situations.
Website hacked, got malware, or having other security concerns? The documentation in Joomla.org has adequate resources to help you out.
