The Korean government and financial sector's cybersecurity regulations are entering an era of significant transformation. The government and the Financial Services Commission have each presented 'National Network Security Policy Improvement Directions' and 'Financial Sector Network Separation Improvement Plan.' It's a major shift across the public and financial sectors. 

Companies will gain new opportunities with the easing of network separation regulations, while the responsibility for cybersecurity will increase. Companies must now autonomously manage and strengthen their security systems. 

An autonomous security system signifies not only changes in technical defense but also fundamental shifts in the philosophy and approach to security.

Until now, the Korean government and the financial sector were encased in the fortress of network separation. This policy has had positive effects in ensuring a certain level of security, but it has hindered work efficiency and innovation by blocking the use of generative AI and cloud technologies. Security teams focused on implementing only what was legally and policy-allowed within the framework of network separation regulations. 

Now, each agency and company must create and implement the optimal security system that fits their individual circumstances. 

Organizations and financial companies are beginning the journey to develop the optimal security system by considering the characteristics and risk level of the data they possess. They must define the data and scope needing protection and take appropriate security measures accordingly. 

In case of a security incident, the responsibility will fall on the agencies and companies. Each agency must increasingly contemplate and choose the most effective security measures. 

The shift to an autonomous security system may impose significant burdens on the security personnel of agencies and companies. Financial sector security teams are already busy finding ways to safely utilize generative AI and cloud solutions. Security experts can leverage this opportunity to enhance their capabilities and play a more significant role within their organizations. 

Companies are busy creating flexible cybersecurity roadmaps.
