The growth of computer networks, most notably the Internet, has made it possible to access corporate networks from not only within the corporation itself, but from a variety of other locations as well. While this has made life more convenient, it has also meant that security problems such as unauthorized access and information leaks have become much more serious.
Security means "safety" and "protection from dangers and risks that can threaten that safety". The following table lists some of the major security threats.
Classification | Concrete example | |
|---|---|---|
Accidental or incidental threats | Natural disasters | Earthquakes, lightning, fire, etc. |
Faults and breakdowns | Hardware and software faults, etc. | |
Human error | Operational errors, incorrect connections, etc. | |
Intentional threats | Malicious action by third parties | Unauthorized access, impersonation, etc. |
Malicious action by related parties | Password leaks, disclosure of customer information, etc. | |
