Hackers are constantly discovering security vulnerabilities in various systems, including web applications and IoT devices. This is largely due to companies neglecting to integrate security into their development life cycle, despite having dedicated security teams. Testing tools, such as Selenium, can be a valuable asset in identifying and fixing these vulnerabilities. OWASP provides a list of common vulnerabilities, known as the Top 10, which web applications are susceptible to. To mitigate these risks, it's essential for developers to educate themselves on security best practices and use tools like Selenium and ZAP to analyze and assess their application's security. By doing so, companies can reduce the risk of being hacked and ensure compliance with industry security standards.
