How Do Data Breaches Happen ?

Data Breaches

The assumption is that a data breach is caused by an outside hacker, but this is not always true.

The reasons why data breaches occur can sometimes be attributed to intentional attacks. However, it can just as easily be the result of simple oversight by individuals or flaws in a company’s infrastructure.

Here’s how a data breach can occur.

  • An accidental insider. An example would be an employee using a colleague’s computer and reading files without having the correct permissions. Access is involuntary and no information is shared. However, because it has been viewed by an unauthorized person, the data is considered hacking.
  • A malicious insider. This person knowingly accesses and/or shares data for the purpose of harming an individual or a business. The malicious insider may have legitimate permission to use the data, but the intention is to use the information maliciously.
  • Lost or stolen devices. An unencrypted and unlocked laptop or external hard drive, anything that contains sensitive information goes missing.
  • Malicious outside criminals. These are hackers who use various attack vectors to collect information from a network or from an individual.
