The technology used to prevent unauthorized access to information systems is known as cybersecurity measures. These measures include techniques such as firewalls, encryption, intrusion detection systems, and multi-factor authentication. By implementing these tools and practices, organizations aim to protect their networks, applications, and data from potential threats. Cybersecurity is essential for safeguarding sensitive information and maintaining the trust of users and stakeholders. Regular updates and assessments of security protocols are crucial to adapt to evolving threats in the digital landscape, ensuring robust protection against unauthorized access and cyberattacks.
