Applicable Levels

service03_check_icon
Level 1: Baseline Security Controls

Purpose

Establish organizational-level minimum security controls to reduce reliance on individual practices and provide basic defense against external threats.

Key Checklist Items (examples)

Information security policies and documented procedures (approved and communicated)
Account management: issuance, role-based permissioning, periodic review, removal on termination
Endpoint protection: antivirus deployment and automatic updates
OS and application patch management (Windows Update etc.)
Portable media and device handling policies (USB controls)
Physical security: access control for offices and server rooms
Basic backup practices and documented recovery procedures

Typical Operational Challenges

Policies are not fully documented or aligned with daily operations
Privileged access is managed inconsistently or manually
Patch updates and security signatures are delayed or unmanaged

Toyo TAS Support Examples

Current-state discovery (interviews, document review) and gap report
Provision of policy and procedure templates tailored to local operations
Implementation support for account lifecycle management process
Endpoint management baseline configuration guidance and checklists
Admin workshops to institutionalize operational controls

Level 2: Monitoring & Operational Controls

Purpose

Build continuous monitoring and operational capabilities to detect and respond to security incidents promptly and reliably.

Key Checklist Items (examples)

Log collection, retention, and review strategy (access logs, auth logs, system logs)
Monitoring rules for anomaly detection and malware behavior alerts
Regular backups and recovery testing with clear ownership
Documented approval and audit trails for privilege changes
Defined security owner/roles for operations and incident handling
Supplier / subcontractor security validation process

Typical Operational Challenges

Logs are scattered across systems, making correlation difficult
Monitoring and alert handling are ad-hoc or person-dependent
Disaster recovery and recovery tests are under-executed or undocumented

Toyo TAS Support Examples

Design of log collection policy and streamlined aggregation approach
Support for implementing a lightweight SOC-like monitoring workflow (log → rule → initial response)
Backup and recovery procedure design and execution of recovery tests
Internal audit checklist creation and auditor training
Standardization of reporting formats for the Japan headquarters

Level 3: Security Culture & Continuous Improvement

Purpose

Embed security awareness and continuous improvement into daily operations so employees proactively contribute to risk reduction and incident handling.

Key Checklist Items (examples)

Regular employee training programs (including onboarding) and post-training assessments
Executive-level security responsibility briefings
Incident response exercises and tabletop simulations with after-action reviews
Periodic risk assessments and a documented improvement cycle (PDCA)
KPI/KRI monitoring (training rates, incident counts, MTTR)
Regular governance meetings to review audit feedback and improvements

Typical Operational Challenges

Training efforts are one-off rather than recurring programs
Awareness and practice vary widely between departments
Reporting culture for minor events is weak, leading to missed early warnings

Toyo TAS Support Examples

Develop and deliver multi-language security training programs (Thai/English/Japanese) tailored by role
Design and run incident response exercises with evaluation reports and improvement actions
KPI and reporting template development for management dashboards
Support for security awareness campaigns and e-learning rollouts
Facilitation of quarterly improvement reviews and governance sessions
