"Unfortunately, cyber threats are an increasingly serious concern for web architects. Hackers are becoming more sophisticated, and their threats' nature is constantly evolving. As a web architect, I need to stay abreast of the latest trends in cyber security and the methodologies hackers use to attract a website. I employ several different defenses to prevent threats, including denial of service, man-in-the-middle, SQL injections, zero-day exploitations, cross-site scripting, and other similar attacks. Techniques I use include robust user authentication, firewalls, complex password requirements, and educating the website's users. These have been effective in my previous roles and have resulted in zero successful attacks in my last three jobs."
