CISO's guide to data minimization | TechTarget
Many enterprise cybersecurity conversations still focus primarily on prevention technologies. While these controls remain critically important, CISOs today recognize that one of the most effective ways to lessen breach impact is far simpler in concept: reduce the amount of sensitive data available to be stolen in the first place. This is the principle behind data minimization.
Data minimization is the practice of collecting, processing, storing and retaining only the data that is necessary for business operations, legal obligations and customer services. Although often discussed in the context of privacy regulations, data minimization has become equally important as a cybersecurity and breach reduction strategy.
For attackers, large volumes of sensitive data represent an opportunity. For defenders, unnecessary data creates operational overhead, regulatory exposure and additional attack surfaces. As enterprise IT contends with ransomware, AI-driven reconnaissance, cloud sprawl, SaaS proliferation and machine identity growth, minimizing sensitive data is becoming a foundational security...
