Data Breach
Data Breach
A data breach is a security incident where unauthorized individuals gain access to sensitive, protected, or confidential data. This unauthorized access often results in the data being viewed, stolen, or used without permission. Data breaches can affect both individuals and organizations and have become increasingly common with the rise of digital information management.
Causes and Techniques
Data breaches can occur due to a variety of reasons, including:
- Weak Passwords: Many breaches occur due to the use of weak or default passwords, making it easier for hackers to gain access.
- Phishing Attacks: Cybercriminals often use phishing tactics to trick individuals into revealing their login credentials.
- Malware: Installation of malware can allow hackers to access sensitive data on infected devices.
- Insider Threats: Employees or individuals within an organization may intentionally or unintentionally compromise data.
- Vulnerabilities in Software: Flaws in software systems can be exploited by attackers to access data without authorization.
