Data breaches within organizations typically occur due to factors such as human error, malware, and social engineering tactics. Inadequate cybersecurity measures or unpatched vulnerabilities can expose sensitive user information to attackers. Phishing attacks may trick employees into revealing credentials, while ransomware can lock data until a ransom is paid. Regular training, software updates, and adopting robust security protocols are essential for mitigating these risks, protecting organizational data, and maintaining customer trust.
