Definition: An Intrusion is any unauthorized access to your information system assets and indicative of a security weakness in the system. Most people fail to realize that a malicious breach to your information security system can either arrive on-line or in person. The illegal access of private information resources is a serious event.  You are responsible for maintaining the confidentiality of personally identifiable information (PII). Unauthorized access to a computer or network will likely result in the disclosure of confidential information and cause damage to the information system.    Regardless, the business operations of the organization could be in jeopardy.  It's possible, depending upon where you live, that you have violated to practice due diligence.

Its Relevance: An invasion of a computer or a network by an unauthorized individual is a serious matter. Individuals and organizations have obligations to maintain and protect confidential information (i.e. bank account numbers, social security numbers, etc.). Loss of proprietary data or control over a network could be disastrous to an organization’s survival and down-stream liability. Unauthorized access to an information infrastructure's digital assets is potentially devastating.
