FIELD: network communication technologies.
SUBSTANCE: invention relates to the field of securing communication networks and can be used to protect service servers from DDoS attacks. Technical problem is the low security of the server services, associated with the need for considerable time to restore it and the lack of additional analysis of the “Black” list of IP addresses to ensure their relevance. Technical problem is solved due to the absence of a break in the maintenance of connections from the “White” list of IP addresses and additional analysis of the “Black” list of IP addresses.
EFFECT: increasing the security of the service server due to continuous maintenance of connections from the “White” list of IP addresses and additional analysis and correction of the “Black” list of IP addresses.
