KT announced on the 15th that it plans to invest more than 1 trillion won in the field of information security over the next five years.
KT is the only telecommunications company that invests more than 100 billion won annually in information security. Based on this investment, KT will pursue four major innovations in information security: ▲ strengthening AI monitoring systems ▲ expanding global collaboration and diagnostic consulting ▲ completing the zero-trust system ▲ increasing dedicated security personnel. In particular, KT said it will operate the "K-Security Framework" to ensure thorough control over the entire process of protecting customer personal information.
"K-Security Framework" consists of "K-Offense," which conducts penetration testing from the attacker's perspective, and "K-Defense," a unified security response system against various attack surfaces, and plans to realize predictive and preventive security. Additionally, it aims to preempt external threats through regular simulated hacking and vulnerability improvement activities.
KT will also mobilize its overall technological capabilities and monitoring infrastructure to collaborate with global security companies, design an AI-based future security architecture, and secure world-class security experts to build a response system. It operates Korea's first integrated cyber security center for IT and networks, and plans to complete its security system by reinforcing the zero-trust system it has been pursuing for two years.
KT is preparing differentiated services to reduce actual damage to customers, in addition to its information security innovations. In the second half of the year, it plans to commercialize "KT AI Voice Phishing Detection 2.0," the next version of its AI voice phishing detection service. This service features AI trained on over 25,000 voice phishing audio data that analyzes the context during calls to detect warning signals and provide alerts to users. The accuracy is expected to improve from 91.6% to 95%, with a goal of preventing criminal damage of over 200 billion won.
Security services for corporations will also be strengthened. KT plans to leverage the latest security threat databases to more than double its DDoS attack defense capacity and establish a proactive DDoS response system through AI-based learning of new threat patterns. Additionally, it will implement features in its "AI Mail Security" service to block threats such as phishing, ransomware, and APT in real-time and add an automatic summary function for threat reports using AI (LLM).
