What is the definition of unauthorized access?

Unauthorized access is defined as the act of gaining entry to computer resources, networks, or systems without the proper permissions or consent of the owner. This encompasses actions taken by individuals who bypass security measures, exploit vulnerabilities, or use stolen credentials to access information or systems they are not authorized to use. The focus is on the lack of consent from the legitimate owner or administrator, making this definition clear and straightforward in regards to the risks and violations associated with data security.

In contrast, access granted by a system administrator, using a password correctly, or retrieving data with proper credentials all involve legitimate and authorized actions. These scenarios emphasize the importance of permissions in cyber security, highlighting that authorized access is acceptable and expected when proper processes are followed.
