Internet Security Awareness Training (ISAT) consists of the training of members of an organization regarding the protection of various information assets of that organization. Organizations that need to comply with government regulations (i.e. GLBA, PCI, HIPAA, SarBox)normally require formal ISAT for all employees, usually once or twice a year. Many Small and Medium Enterprises (SME’s) do not require ISAT for regulatory compliance, but train their employees to prevent a cyberheist.
Internet Security Awareness Training at this point in time is usuallyprovided via online courses. ISAT is a subset of general security awareness Training.
