• Global IT Integration: Lead IT system integration projects for multinational subsidiaries; develop IT governance policies that comply with local regulations and global corporate standards.
• Information Security & Endpoint Protection: Implement endpoint security policies (user access control, patch management, antivirus, endpoint protection); establish Data Loss Prevention (DLP) measures to monitor and prevent information leakage.
• Risk Control & Compliance: Define IT security standards and audit mechanisms to comply with international frameworks (e.g., ISO 27001, GDPR); conduct periodic vulnerability assessments, penetration testing, and staff training.
