Cybersecurity plays a vital role in protecting sensitive information by implementing various security measures to defend against unauthorized access, data breaches, and cyber threats. This includes the use of encryption, firewalls, and multi-factor authentication to secure data both in transit and at rest. Additionally, cybersecurity practices involve regular assessments and updates to address vulnerabilities proactively. By ensuring the confidentiality, integrity, and availability of information, cybersecurity is essential for sustaining trust in digital systems and safeguarding critical assets in personal, business, and government contexts.
