Why Data Breaches Happen

A data breach may occur for a number of reasons. For example, a data breach could be the result of unauthorized acquisition of personal information through employee negligence (i.e., photocopying) to computer hard drives not properly disposed of, to hackers gaining access to data through an exploit or other malicious attack.

Data Breach Notification Laws

Many countries or individual states/provinces have enacted some type of security and data breach notification law. These laws require government agencies and other organizations that collect personal information (including a name combined with SSN, drivers license or ID, account numbers, etc.,) to notify individuals of security breaches.

The exact requirement for notification laws change between places as well as the legal definition of what constitutes a breach, requirements and timing for notice and exemptions. In general if there is a perceived risk as a result of a data breach, the affected individuals and regulating government bodies should be notified.

Data Breach Security Checklist

While there are no specific set of rules to follow, most organizations will create a checklist to ensure a swift response to manage and mitigate a breach.

The data breach procedure is typically reviewed, tested and enacted as part of an organization's overall business continuity and disaster recovery procedure. The related links section below offers additional resources to help businesses create checklists and data breach policies.
