In Financial AI Security (PART 1. Basics), I provided an overview of AI security. Please note that this is a practitioner's training session on the AI inspections required during actual security reviews for penetration testers (Red TEAM). This lecture contains practical content and explains how to perform penetration testing on technical aspects (including checklists). When studying, you may find AI difficult, or you might find that many companies have failed to apply AI guidelines because they are focused on modeling, making reviews challenging. I expect many companies have received various feedback during audits regarding the establishment of AI security governance. This is naturally because there is no clear evidence of AI security within internal operations. Now is the time to establish it. I hope you study AI security and pursue a path as an AI security professional.

Finally, I feel that the AI security review (NIS/FSI) checklists, which have been vaguely positioned over the past 7–8 years, are now accurate from a practitioner's perspective, and I have established a clear framework for how to change, establish, and operate the management system. I will explain what AI security is and how it should be improved after June 2026, based on the standards of South Korea's top-tier companies (those with the highest level of information security). (This is not a basic or conceptual explanation*) I have developed this training divided into PART 1 (Basics & Overview) and PART 2 (Advanced & Security Review), so please refer to it.

This training was created to first help privacy officers recognize and understand the requirements for establishing a proactive protection system, as previously announced through the June 2026 Personal Information Protection Act and the Personal Information Protection Commission's (PIPC) compliance inspections. It aims to help companies review their current status, identify areas for improvement, and establish future action plans. Based on over 8 years of experience in providing advisory and consulting services for personal credit information protection, this course is designed to support strategy formulation and the preparation of reporting documents for executive management.

The shortage of PMs in security consulting firms is a persistent issue. Consequently, there are many cases where individuals in their 40s and 50s from completely different fields have been entering the industry to handle PM duties and client communications. Since these PMs in their 40s and 50s lack experience in technical areas, consulting, and security, they find the work very challenging. They often join with the mindset of learning through handovers from other PMs. I have also been providing training and handovers to these PMs based on the following content, and the satisfaction levels have been high.

Achieved the highest rating for all clients over 6 years of performing Personal Information Protection Level Evaluation consulting for public institutions (covering various types from central administrative agencies to public enterprises, small-scale public institutions, and local governments), maintained the highest rating for all (continuous consulting experience with the same institutions), and holds a track record of achieving a perfect score of 100 (ranked 1st nationwide). Based on the 2026 manual, it is possible to effectively allocate the necessary tasks and performance records for writing quantitative/qualitative reports considering the strengthened penalties and changed indicators following the Coupang incident. Depending on the company's situation, it is fully possible to be designated as a best practice through either over-investment or strategic passive response.

Insufficient capability to audit new technologies (cloud management systems) due to a lack of theory and knowledge among management system inspection personnel. Training to strengthen the expertise of personnel who proactively prevent incidents by identifying management system deficiencies to protect companies from hacking. Training for existing infrastructure and penetration testing personnel to transition into management system roles. Securing definitive capabilities and materials through the provision of back data!

In cases where there is a lack of experience with electronic financial infrastructure due to only having experience in critical information and communications infrastructure, or where there is a lack of overall understanding of infrastructure projects due to insufficient experience as an Infrastructure PL or PM despite having experience with servers, DBs, networks, and security equipment, it is necessary to secure assessment capabilities for network infrastructure check items and provide assessment back-data.

As PaaS (previously categorized as WEB/WAS) in public and private cloud environments is integrated into in-house PaaS operations, this training is designed for Infrastructure Project Leaders (PLs) overseeing approximately 10 infrastructure inspection personnel, as well as vulnerability assessment specialists. The curriculum covers certification requirements such as ISMS-P, including cloud asset identification, asset classification, importance rating, and risk assessment reflection. It also addresses the 2026 Financial Company Security Standards (for Electronic Financial Infrastructure Vulnerability Analysis and Evaluation), which include the establishment and strengthening of container inspection and private cloud management system inspection items, as well as the addition and modification of virtualization and cloud items within Critical Information and Communication Infrastructure.

Lack of back data for private cloud inspections!! A severe shortage of experienced personnel for IaaS inspections!! Improve practical skills by providing back data and utilize it for various certifications such as Major Information and Communication Infrastructure, Financial Security Institute (FSI) assessments, ISMS-P, ISO27001, etc. Professional training for Infrastructure Project Leaders (PLs) who manage around 10 infrastructure inspection personnel. Providing inspection data and understanding of the technical areas within the cloud management framework!

Providing insights and materials for overall management of penetration testers (WEB, Mobile, HTS) targeted at Project Leaders who oversee financial company mock hacking/penetration testing. Situations have occurred where "blank" reports are repeatedly submitted when no vulnerabilities are found in each part (the same applies to the public sector). Therefore, controls are implemented to ensure that inspection results for each item are produced in the same format as educational materials. Perform inspections tailored to each theme and utilize them for security reviews and internal security deliberations to verify results.

Conducting Windows server competency training to break the trend of new and career-transitioning security consultants focusing solely on Linux servers.

Understanding vulnerabilities and continuing vulnerability assessment and improvement activities.

Education on the most basic Linux server inspection methods and items due to the continuous assignment of new security consultants for vulnerability assessment and the continuous placement of experienced professionals from other fields into management roles. Risk assessment for risk evaluation (remediation planning) and implementation review. Understanding and application of third-party security solutions. Establishment of the ISMS-P management system through appropriate analysis of technical and administrative domains.

Classification of inspection items and establishment of an inspection plan (strategy) during network inspection Establishment of inspection criteria considering the risk and difficulty of actions Inspection of network service items and strategies for utilizing server access control solutions Command-based inspection after remote network access and preparation of risk assessment reports Interviews with network personnel and application of manual inspection items

A lecture for security consultants who have experience only in Linux, DB, WEB, networks, and security equipment, but lack experience with PCs. Securing response capabilities for cases where PC inspections are replaced by security solutions or conducted via scripts. Categorizing inspection items to prepare inspection strategies and establish response strategies based on inspection experience. One of the business improvements (KPIs) to shorten inspection time and increase accuracy.

Security equipment cannot be inspected using scripts or solutions like databases. Experienced personnel must be assigned. Difficulty in recruiting, including experienced individuals, diligent diagnosticians, or freelancers. Numerous defects found during ISMS-P certification of security equipment; skill levels vary significantly depending on the inspector. Sharing inspection methods and management strategies (methodologies, etc.) for security equipment with those who need them.

Database vulnerability assessment training for the protection of critical information and communication infrastructure in the public sector. Demand for vulnerability assessments arises as a legal requirement. Characterized by the need to secure sufficient assessment time and budget, particularly in the public sector. Lack of specialized personnel for vulnerability assessments in the public sector. Lectures for establishing protection measures in response to revisions of critical information and communication infrastructure and annual changes.

This content is composed of insights from experienced professionals—ranging from newcomers to those with 35 years of experience—performing vulnerability analysis and evaluation for Financial Security Standards and Major Information and Communication Infrastructure. It is designed to provide valuable information for new employees or experienced professionals transitioning from other fields. Among the various types, Database was selected, and the evaluation criteria are based on the Financial Security Standards. While basic training or handovers are typically based on the previous year's standards, I believe it would be helpful to familiarize yourself with various analysis techniques as well. Since diverse strategies are required for accurate and rapid diagnosis within a limited timeframe, this may also be beneficial for PMs who plan from the perspective of methodology and approach.

As AI systems become agentic and expand beyond text into image, audio, and multimodal capabilities, security threats are becoming significantly more complex. This lecture analyzes the latest security threats and attack techniques faced by AI Agents and Multimodal LLMs, as well as real-world cases, from an AI Red Teaming perspective.

Feeling overwhelmed by where to start with AI auditing? AI has moved beyond a mere technology trend and is rapidly expanding into corporate decision-making, workflow automation, customer service, recruitment, security, and risk management. However, compared to the speed of AI adoption, not many people systematically understand questions like: "Is the AI being properly controlled?", "Can we trust the AI's judgment?", or "What risks could arise from the data, models, and operational processes?" In particular, those working in IT auditing, security, internal control, and project management often face these concerns: - How does AI auditing differ from traditional IT auditing? - Is it enough to just look at the code for an AI model, or must we examine the data and training process as well? - How do AI governance, risk, bias, explainability, MLOps, and incident response connect to one another? - Where should I start to understand the concepts covered in AI auditing certification courses like AAIA from a practical perspective? This course was created specifically to resolve this sense of uncertainty. For about 20 years, I have gained experience in IT service planning, development, PM, collaboration platform operation, groupware construction, chatbot service planning, and security and audit-related tasks. I have firsthand experience in how systems are planned, developed, and operated in actual organizations, and how failures, changes, security, and user requirements are interconnected. Furthermore, I have synthesized the perspectives of IT auditing and AI auditing through CISA and AAIA study programs. In this course, rather than diving deep into complex AI technology through math or development, I focus on the core concepts that auditors and IT practitioners must understand. We will examine AI systems by breaking them down into the flow of data, models, operations, security, governance, risk, and audit procedures, and summarize what controls and checkpoints are required at each stage. Through this course, students will understand that AI auditing is not simply "evaluating AI," but rather the task of inspecting governance, risk, and control systems to ensure that AI is used safely and responsibly within an organization. This course is suitable for: - Those new to AI auditing. - Those in IT auditing or security who want to expand into the AI domain. - Those who want to organize AI governance and risk from a practical perspective. - Those who want to grasp the overall concepts before starting AI audit-related studies such as AAIA. Upon completing the course, you will be able to answer the following questions yourself: - What components make up an AI system? - What should an AI auditor check during the data, model, and operation stages? - Why are AI governance and Responsible AI important? - How are AI risk, bias, explainability, privacy, and security connected? - What perspectives and evidence should be included in an AI audit report? In the rapidly changing era of AI, the ability to manage and inspect technology to make it trustworthy is just as important as the ability to use it well. This course is an introductory program for those who want to understand the big picture of AI auditing step-by-step from the beginning. Let's build the first standard for looking at IT and AI from an auditing perspective together.
