A data breach occurs when unauthorized individuals gain access to sensitive information, such as personal data, financial records, or confidential business information. This can happen through various methods, including hacking, phishing, or physical theft of devices. Once the data is compromised, it can be misused for identity theft, fraud, or other malicious activities. Organizations often store large amounts of data, making them attractive targets for cybercriminals. To protect against data breaches, companies implement security measures like encryption, firewalls, and regular security audits. However, even with these precautions, breaches can still occur, highlighting the importance of vigilance and quick response strategies.
