thought of as risks that are outside the control of the organization. While internal threats are within the boundary of the organization. They could be related to employees or other personnel who have access to company resources. Internal threats can be related to any hardware or software controlled by the business.
Natural or man-made- Natural threats are often related to weather such as hurricanes, tornadoes, and
ice storms. Natural disasters like earthquakes and tsunamis are also natural threats. A human or man- made threat is any threat which is caused by a person. Any attempt to harm resources is a man-made threat. Fire could be man-made or natural depending on how the fire is started.
Intentional or accidental- An attempt to compromise confidentiality, integrity, or availability is intentional.
While employee mistakes or user errors are accidental threats. A faulty application that corrupts data could also be considered accidental.
