Security Testing

As enterprise digitalization and digital transformation trends emerge, technology has improved efficiency, but it can also lead to hidden information security risks. If any weaknesses or vulnerabilities in information systems are not identified and fixed, they can easily become attack targets for hackers. Organization members need to raise their information security awareness to prevent any property or reputation loss that may be caused by human errors. Thus, enterprises must take preventive action by performing information security tests.
