2. Security Breaches and Legal Insights
⚠️ Editor's Note: No new definitive court rulings were collected after 2026-04-12. The following summarizes legal implications discussed in reports published during this period.
① Personal Information Protection Act Amendment: CEO Accountability Clarified
Following the passage of the amendment on February 12, 2026, business owners and CEOs are now legally obligated to implement comprehensive management measures, including securing specialized personnel and providing sufficient budget for privacy protection. This shifts responsibility from mid-level managers or CPOs directly to the executive level.
② Mandatory ISMS-P Certification and Breach Response Upgrades
According to an analysis by Jipyong in the Law Times, the amendment mandates ISMS-P certification for designated data processors. To allow time for budget allocation and preparation, this takes effect on July 1, 2027. Furthermore, stricter requirements for responding to security breaches under the Telecommunications Network Act will begin in 2026.
③ Lexology: Strengthening CPO Roles and Mandatory Certification
An analysis on Lexology suggests that the amendment aims to strengthen the responsibility of leadership while ensuring the practical authority and independence of CPOs to foster a proactive, prevention-centered culture. Businesses face increasing legal and practical pressure to grant CPOs real decision-making power.
