In a pure mathematical attack, (i.e., lacking any other information to help break a cipher) two factors above all count: 1  Computational power available, i.e., the computing power which can be brought to bear on the problem. 2  Key size, i.e., the size of key used to encrypt a message.
OMB's guidance to agencies requires them to report each PII-related breach to DHS's U.S. Computer Emergency Readiness Team (US-CERT) within 1 hour of discovery. However, complete information from most incidents can take days or months to compile; therefore preparing a meaningful report within 1 hour can be infeasible.
The HIPAA Breach Notification Rule, 45 CFR Â§Â§ 164.400-414, deals with unauthorized disclosures of covered information. It is a specific regulation requiring any individual or organization covered by HIPAA rules to report such breaches, regardless of why they occur. These rules of reporting a HIPAA breach apply to all covered entities, vendors of public health records, and their third party providers. This rule has also recently been interpreted to include business partners who might not otherwise covered by HIPAA regulations.
