What Is a Data Loss?
A data breach can be defined as the unauthorized or intentional release of sensitive or personal/private/confidential personal or financial information from an unauthenticated and unprotected environment to an unauthorised third party. These incidents have become more common in the past few years as online transactions and file sharing have become popularized. There are several types of data breaches that occur in the electronic world: a data loss that can be caused by a computer crash, data loss that is caused by a virus, data loss that is caused by malware or data loss that is caused by a physical theft. Other names for the phenomenon are accidental information disclosure, accidental data leakage, information spill and data breach. All of these incidents are equally devastating.
A data loss may be caused by a single person who has malicious intent. The most common example is someone who is disgruntled or fired and intends to gain access to sensitive data. This type of situation may be a business or a personal issue where there is a dispute between a boss and employee. A data loss could be caused by a software program that accidentally goes wrong and destroys data. Most of these events happen accidentally and may take weeks before the actual damage is done, but the consequences are far reaching.
Data leakage is another example of a data loss and occurs when data is stolen from a network such as an Internet service provider (ISP). In a data leak, a hacker uses the knowledge of a password or encryption scheme to gain access into the computer systems of the ISP. In a data leakage incident, the thief does not need to access sensitive information in order to gain access. The thief can simply access the system and gain access to sensitive information on the server.
A data spill happens when a hacker deliberately causes the leakage of sensitive information. The leak could be caused by a virus, malicious software or even human error. This kind of data leakage is not as easy to detect because it can occur when information is stored in a system and is not accessible by the system administrator for weeks or months.
The last example of a physical theft involves data that is stolen or lost through a burglary. In a physical theft, the thief uses the system’s access card or other equipment to gain access to the system. They may also break into the system and steal personal information. A physical theft is usually harder to detect because the system may be physically broken into or even physically stolen.
Each of these scenarios is a cause for concern for businesses and consumers alike because of the impact that a data loss can have on business and personal life. These incidents are often the result of a data breach or a data spill. To prevent data loss and data leaks, it is essential for businesses and individuals to have a solid network security plan, including firewalls and security applications.
