Cybersecurity measures to protect sensitive data include encryption, which scrambles data to prevent unauthorized access, and firewalls that monitor and control incoming and outgoing traffic. Multi-factor authentication adds an extra layer of security by requiring additional verification methods. Regular security audits and vulnerability assessments help identify and mitigate potential risks. Employee training on phishing and social engineering tactics also plays a crucial role in maintaining security. Lastly, adhering to compliance mandates such as GDPR and HIPAA ensures that companies follow best practices in protecting sensitive information.
