In the context of finance and investments, exposure refers to the degree to which an investor or business is open to risk from market fluctuations, which could potentially lead to loss. In cybersecurity, exposure denotes the vulnerability of an organization or individual to potential threats that could lead to unauthorized access or damage to information systems and data. It is often used to measure the risk associated with network interfaces, code, or practices that make a system susceptible to cyberattacks. Reducing exposure is key to strengthening the security posture.
