Have you ever wondered how real attackers carry out cyberattacks? BHPT is a comprehensive, hands-on course that uses on-demand labs to simulate penetration testing from an attacker's perspective on specific hosts, teaching methodologies for discovering, attacking, reporting, and responding to vulnerabilities.

The PNT course is a hands-on course designed to follow the BHPT course and teach the concepts of pivoting and tunneling, which are necessary for lateral movement within a network. Students will learn pivoting techniques to bypass firewalls by manipulating network traffic and learn how to cross boundaries in various network environments through a practical lab.

Develop a system to submit annual activity performance including establishment of information security regulations and preparation of various activity evidence by applying domestic and international certification standards related to information protection management systems and internal/external audit criteria for Risk assessment standards for management and physical sectors of major information and communication infrastructure facilities revised in the second half of 2025. Establish activity plans for enhancing information security levels compared to last year in response to external environmental changes (AI, etc.), internal environmental changes (new systems and employee changes including external staff), and prepare for legal amendments and new evaluation indicators. In particular, objectively and thoroughly inspect various activities to strengthen accident prevention systems such as personal information leakage due to hacking, establish plans for central (headquarters) management and supervision of all departments and safe management and supervision of service companies, operate DevSecOps systems following the establishment of AI systems, operate PbD adequacy review systems, etc. Based on performing expanded monitoring areas, regular inspection report areas, external disclosure areas, data integration system inspections (API, MyData, etc.), establishment of network separation improvement plans according to N2SF, advancement of Zero Trust application, etc. *Possessing over 150 references for establishing and applying world's first highest-level information security and personal information protection activity and system enhancement plans
