KT (030200.KS) is launching a sweeping security overhaul by integrating its previously dispersed security functions into a single Information Security Division and restructuring its company-wide security framework. Analysts say CEO Park Yoon-young is signaling that security will be the top management priority following last year's hacking incident.
According to KT on Tuesday, the revamped security governance structure will operate as a company-wide integrated system centered on the Chief Information Security Officer (CISO). KT has established a unified execution framework spanning organization, personnel, and budget. The move shifts company-wide security risks to be managed directly at the top executive level.
The telecom operator will also run a company-wide consultative body to integrate the management of security risks across information technology (IT), networks, and all service areas. In particular, KT has redesigned its entire breach response process to ensure faster and more consistent responses in crisis situations.
The security paradigm will shift away from reactive responses toward continuous prevention and preemptive action. Accordingly, KT will apply a "Zero Trust" architecture that continuously verifies all access regardless of whether it originates internally or externally across its company-wide systems. The company also plans to expand AI-based security management, including simulated hacking using artificial intelligence (AI) agents.
KT will also upgrade its integrated security monitoring system to strengthen real-time capabilities for detecting and blocking threats in advance. The company will enhance security controls over both tangible and intangible assets, including in-home terminals, outdoor base stations, and software, while tightening procedures for verifying security vulnerabilities from the equipment supply stage.
The personal data protection framework will also be fully revamped. KT plans to refine its internal management system centered on the Chief Privacy Officer (CPO) and strengthen board reporting to raise compliance standards. An advisory committee composed of external experts will continuously review the security and personal data protection frameworks to ensure objectivity and credibility.
"Centered on the Information Security Division, we will establish a foundation of trust that safely protects our customers' daily lives and data," said Lee Sang-woon, KT's CISO and Executive Vice President. "We will build a security framework that can reliably support our leap into an AX platform company."
