Data security refers to the protective measures applied to prevent unauthorized access, corruption, or theft of digital information. It ensures the confidentiality, integrity, and availability of data across its lifecycle.
It's crucial for protecting sensitive customer and proprietary information, maintaining privacy, ensuring regulatory compliance, and safeguarding against financial losses and reputational damage from breaches.
Common threats include phishing attacks, malware (like ransomware), insider threats, denial-of-service (DoS) attacks, and exploitation of unpatched software vulnerabilities.
Individuals can use strong, unique passwords, enable multi-factor authentication, be cautious of suspicious links, keep software updated, and regularly back up important data to secure locations.
Encryption transforms data into a coded format to prevent unauthorized access. It's a fundamental data security measure, especially for sensitive information, ensuring that even if data is stolen, it remains unreadable without the correct key.
