With ever-widening globalization and digital transformation

multinational firms are becoming increasingly concerned with cross-regional information and cyber security issues. Business systems

data resources

and management are more connected across headquarters

regional centers

overseas branches

and supply chain partners

which improves collaboration efficiency and resources

but may also lead to a more complex attack surface

cross-border data flows

and security management requirements of the system. Multinational firms can not only face technical risks such as ransomware attacks

supply chain attacks

account hijacking

vulnerability hijacking

and internal control failures

but also regulatory requirements from countries and regions regarding cyber security

data protection

personal information

log auditing

and cross-country data transfer. Thus

this study examines the cyber security situation

major risks

capability-building framework

implementation path

and management of multinational firms. Based on the analysis of network boundary losses

terminals and hosts

data protectivities

security operations

and organizational governance

this report proposes a capability-reading framework consisting of a security technology system

a security management system

an information security system

and a security operations system

as well as a phased security implementation

a compliance closed loop

and operations management. In this paper

the authors argue that multinational corporations should integrate compliance management

technical protection

continuous operations

and cross-national collaboration into a single framework to achieve high security robustness and ensure stable

compliant

and sustainable development of global operations.
