Data Breaches and the CISSP Exam
In an effort to combat identity theft, many U.S. states have passed disclosure laws that compel organizations to publicly disclose security breaches that may result in the compromise of personal data.
Although these laws typically include statutory penalties, the damage to an organization’s reputation and the potential loss of business — caused by the public disclosure requirement of these laws — can be the most significant and damaging aspect to affected organizations. Thus, public disclosure laws shame organizations into implementing more effective information security policies and practices to lessen the risk of a data breach occurring in the first place.
By requiring organizations to notify individuals of a data breach, disclosure laws enable potential victims to take defensive or corrective action to help avoid or minimize the damage resulting from identity theft.
Passed in 2003, the California Security Breach Information Act (SB-1386) was the first U.S. state law to require organizations to notify all affected individuals “in the most expedient time possible and without unreasonable delay, consistent with the legitimate needs of law enforcement,” if their confidential or personal data is lost, stolen, or compromised, unless that data is encrypted.
The law is applicable to any organization that does business in the state of California — even a single customer or employee in California. An organization is subject to the law even if it doesn’t directly do business in California (for example, if it stores personal information about California residents for another company).
Other U.S. states have quickly followed suit, and 46 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands now have public disclosure laws. However, these laws aren’t necessarily consistent from one state to another, nor are they without flaws and critics.
For example, until early 2008, Indiana’s Security Breach Disclosure and Identity Deception law (HEA 1101) did not require an organization to disclose a security breach “if access to the [lost or stolen] device is protected by a password [emphasis added] that has not been disclosed.” Indiana’s law has since been amended and is now one of the toughest state disclosure laws in effect, requiring public disclosure unless “all personal information … is protected by encryption.”
Finally, a provision in California’s and Indiana’s disclosure laws, as well as in most other states’ laws, allows an organization to avoid much of the cost of disclosure if the cost of providing such notice would exceed $250,000 or if more than 500,000 individuals would need to be notified. Instead, a substitute notice, consisting of e-mail notifications, conspicuous posting on the organization’s website, and notification of major statewide media, is permitted.
