Recovery, Renewal, Resilience

In Korea the following processes have been put in place for civil servants and these lessons could be expanded to other organisations:

Expand systems and optimizing resource

• Expanding the number of VPN licenses from 24,000 to 40,000, an increase of 16,000
• Optimizing load distribution methods to manage web server traffic
• Increasing the maximum network capacity (national information telecom networks and VPN broadband from 1G to 4G)

Support VPN use among employees working from home

• Distributing signup guidelines, user manuals, and FAQs
• Training for using VPN via video conference for workers, especially those in government institutions to improve security of sensitive information
• Workers who work from home have call centres available from 9 am to 6 pm (including at the weekend)

Monitor the daily system

• Monitoring trends in number of subscribers, usage traffic, simultaneous log-ins, and networks e.g. Personal Area Network (PAN), Local Area Network (LAN), Wireless Local Area Network (WLAN) etc
• Monitoring heavy traffic hours with the highest number of people logged onto the internet simultaneously (between 8 am and 10 am)
• Focused monitoring every 10 minutes

In Korea, The Cellular Broadcasting Service enables government agencies to transmit text messages to cell phones through mobile telecom carriers in Korea. This service is particularly useful during an emergency but also builds resilience into the system for the future.

Metropolitan and local governments in Korea are equipped with a system that can send messages to their residents without having to receive approval from the Ministry of the Interior and Safety (MOIS). This allows them to make their own locally relevant decisions.
