Financial Sector Use Case

    AI Security Strategy for Financial Institutions

    Security control direction and the role of AI DLP as generative AI adoption expands

    For Security, Compliance, IT Planning & AI Teams | Based on Electronic Financial Regulations (2026.4.20) & FSC AI Guidelines (2026.6)

    Current Challenges

    'Should we use AI?' is no longer the question — 'How do we use it safely?' is

    The April 2026 network separation relaxation enables broader cloud AI and collaboration tool use.

    Responsibility for controls shifts from regulation to internal financial institution systems.

    Data Leakage

    Employees entering customer PII, credit info, internal docs, or source code into external AI via prompts or file uploads

    Shadow AI

    Use of unauthorized AI services or personal accounts makes it impossible to track who sent what and where

    Lack of Control

    Binary allow/block approach cannot provide role-proportionate, risk-level controls

    Audit Gap

    Prompt input history is not captured by existing web/email/document security logs, making 'when/who/what' impossible to prove in incidents

    Financial Sector AI Guidelines (2026.6)

    7 Principles & Security Control Requirements

    While the guidelines assume voluntary adoption, the 7 principles serve as a common baseline for financial AI adoption. The Security principle directly connects to AI DLP requirements.

    ①

    Governance

    Executive oversight, role assignment, AI governance

    ②

    Legality

    Compliance with financial & AI regulations throughout all stages

    ③

    Supplementary Use

    AI as a tool; final decisions and accountability rest with employees

    ④

    Reliability

    Use of reliable data and models

    ⑤

    Financial Stability

    Minimizing financial stability risks throughout design and training

    ⑥

    Good Faith

    Prioritizing the interests of financial consumers

    ⑦

    Security

    Key

    Security standards and inspection frameworks, including detection and masking of sensitive I/O data

    Electronic Financial Supervision Regulation (2026.4.20)

    Regulatory Requirements Directly Linked to AI DLP

    Network separation relaxation is a transfer of control responsibility, not a loosening of controls.

    Financial institutions must implement their own input-stage monitoring and logging.

    Security Principle — Sensitive I/O Control

    Implement functions that automatically detect and mask or remove personal/credit data and other confidential information found in AI inputs and outputs

    Security Principle — Overseas Transfer & Reuse Check

    When using commercial GenAI, confirm data's potential overseas transfer and verify that input data will not be reused for model training

    FinTech Security — Terminal Upload Control

    For terminals querying GenAI, implement upload monitoring and blocking, encryption of sensitive data, and media control measures to prevent leakage

    Network Separation Alternative — Monitoring, Logging & Access Control

    Monitor and control entry/processing/leakage of sensitive data / Collect logs during access and use / Control external internet access beyond approved SaaS / Control third-party app and plugin connections

    GenAI Security Management Areas

    6 AI Security Areas Financial Institutions Must Manage

    Six security management areas reorganized from a practical perspective based on guideline and regulatory requirements.

    AI Usage Visibility

    Visibility into which AI services employees use and what data they share

    Guideline 7.5 / Regulation §2-2

    Shadow AI Detection

    Identify unauthorized services and personal account usage; control external connections

    Annex 7 Access Control / Guideline 7.7

    Input Data Control

    Detect and block entry of personal IDs, credit info, and internal documents

    Guideline 7.2 / Annex 7 Sensitive Data

    File Upload Control

    Detect and block sensitive files uploaded as attachments to AI services

    FinTech Security 3.1 / Annex 7

    Sensitive Data Loss Prevention

    Auto-detect, mask, remove, or block personal and credit data at I/O stage

    Guideline 7.2 (p.71–73) / PIPA

    Audit Log

    Maintain tamper-proof logs of all AI interactions for audit and incident response

    Regulation §2-2 / Annex 7 Log Collection

    FlowGuard AI DLP Scope

    Clear Distinction Between What FlowGuard Covers and What It Does Not

    FlowGuard is not a complete regulatory solution but one applicable tool within a broader security control framework.

    FlowGuard Covers

    • Detect endpoint access to GenAI services (ChatGPT, Copilot, Claude, etc.)
    • Classify approved/unapproved AI services and identify Shadow AI
    • Real-time detection of personal info, credit data, and internal documents in prompts
    • Policy-based blocking, warning, and user justification request
    • Detect and block sensitive file uploads
    • Retain full AI usage logs and generate audit reports
    • Endpoint-based monitoring to support Annex 7 alternative control compliance

    Outside FlowGuard's Scope

    • Security and safety validation of AI models themselves
    • Regulatory reporting, licensing, and compliance procedures
    • Server/infrastructure-level security controls for AI systems
    • Network firewall or proxy-based blocking

    Security controls outside this scope should be implemented alongside separate solutions or internal institutional frameworks.

    Implementation Approach

    Diagnostic PoC-Centered Limited Scope Approach

    We recommend a phased approach that accounts for the complex regulatory environment and security review procedures of financial institutions.

    01

    Current State Diagnostic PoC

    Visualize which AI services are used and what data is entered for a limited department/group. Measure security risk level before deciding on full deployment.

    02

    Policy Configuration & Pilot

    Configure detection/blocking policies aligned with FSS guidelines and Annex 7 requirements. Validate false positive rate and business impact in a pilot department before adjusting policies.

    03

    Full Deployment & Audit Framework

    Deploy organization-wide and establish AI usage dashboard, audit logs, and semi-annual compliance reporting. Auto-generate evidence documentation for FSS examinations.
