Data breach is when sensitive, protected or confidential data is accessed and/or disclosed without proper authorization. It typically occurs as a result of a malicious act or system flaws that allow unauthorized access to a computer or computer network. Data breaches can occur in both physical and digital forms, and can involve the theft or exposure of any type of confidential data, including usernames, passwords, banking information, customer information, medical records, Social Security numbers, and trade secrets.
A data breach can have serious financial and legal consequences for an organization. Data breaches may result in identity theft, financial losses, and a decrease in customer trust. Organizations are increasingly relying on sophisticated measures like encryption, antivirus software, and mobile device management to protect their data from being breached or tampered with.
Data breaches are becoming increasingly common as cyber-attacks become more sophisticated and malicious actors become more adept at exploiting system vulnerabilities. Most data breaches occur when an attacker steers undetected through a network, either by physically breaking in or by infiltrating through an existing vulnerability. The compromised data can then be used to launch further attacks, access confidential systems, or be sold to other cyber criminals.
In some cases, data breaches are the result of employee errors or negligence. An employee may accidentally leave a device containing sensitive information in a public space, or access a corporate system with unauthorized credentials. Human error can also lead to data breaches when employees mishandle paper records or fail to secure their passwords.
Data breaches can be extremely damaging to an organization’s reputation, customer trust, and bottom line. Organizations should take proactive steps to ensure that their data systems are secure and have safeguards in place to detect and respond quickly to any potential breaches.
