Chef Secure's Ultimate XSS Training Course specializes in making sure students and engineering teams understand XSS attacks, exploits, defenses and prevention strategies through practical experience-based learning.
Simply put — cybercriminals can't be stopped if their attacks aren't fully understood.
Built-in protections are no longer enough to stop XSS on the web.
Students and engineers need hands-on experience working with the latest attacks and defenses in order to stay ahead of today's attackers.
This course teaches how to:
Discover critical XSS vulnerabilities in web applications.
Analyze and stop malicious exploits from criminal hackers.
Fix XSS vulnerabilities with tactical precision, total accuracy and swift urgency.
Secure applications with proactive defenses that stop vulnerabilities before reaching production.
BOTTOM LINE: Fixing XSS vulnerabilities costs more than the full price of this course.
MAKING THE CASE
Next comes the total cost of the vulnerability's lifecycle:
To make matters worse, the cost of an XSS vulnerability grows exponentially when its exploited and causes damages with legal consequences, ruined brand reputation and loss of customers.
