KSZI as an Architectural Standard: Transition from “Paper” Protection to a Systemic Model

In 2018, the digital transformation of public services requires a rethinking of classical security approaches. The traditional view of the Complex Information Protection System (КСЗІ) as a final stage before certification becomes a critical error. IQusion IT LLC (IQusion) implements a methodology where КСЗІ is not an external superstructure, but the foundation of the architecture of state IT systems.

We view security as a living system, integrated into every API request and every data transaction, ensuring the real resilience of state registers in an aggressive cyber environment.

KSZI as Part of the Architecture, Not a Separate Stage

In outdated models, system development and its protection were separated in time. The modern Security by Design approach implies that КСЗІ requirements are laid down at the stage of designing the database and application logic.

The systemic approach includes:

Requirements Decomposition: Each regulatory requirement of GZI (information protection norms) is transformed into a specific technical function of the software code.

Environment Isolation: Separation into development, testing, and production contours according to security policies.

Integrity Control: Automated mechanisms for checking code and configurations for compliance with the reference state.

Integration of KSZI into an API-first Environment

The state’s transition to microservice architecture and interaction via API creates new challenges. In the IQusion model, protection is not limited to the network perimeter — it becomes “molecular.”

Each API interface is designed with strict authentication and authorization in mind. The use of API Gateway allows for centralized application of КСЗІ policies to all incoming and outgoing data flows, ensuring encryption and access rights verification at the entry point.

Interaction of Protection Contours with the Integration Bus

The central element of modern state systems is the integration bus (ESB). In the IQusion concept, the bus acts not just as a transmission channel, but as a guarantor of secure interaction between various departmental contours.

Operating Mechanism:

Message Validation: The bus automatically checks the structure and origin of data before transmitting it to the protected register contour.

Gatewaying: Creation of controlled transition points between zones with different levels of trust (e.g., between a public web portal and an internal database).

Transaction Audit: Every action in the bus is logged in an immutable event journal, which is a basic requirement for КСЗІ certification.

Technology Stack for Compliance Assurance

Component	Function in the KSZI Model
PKI / КЕП	Legally significant user identification and signing of each operation.
SIEM	Centralized collection and analysis of security events for immediate incident response.
IDM (Identity Management)	Automated management of account and role lifecycles.

Automated Compliance Audit

The transition from formal compliance to systemic compliance means abandoning “one-time” checks. IQusion implements automated audit tools that, in real-time, compare current system settings with the requirements of the technical specification for КСЗІ.

This allows state bodies to be confident in security not only on the day of receiving the compliance certificate but also throughout the entire period of system operation.

For IQusion IT, building КСЗІ is the process of creating a reliable and manageable IT architecture. By integrating security into API interfaces and service buses, we transform formal requirements into a real tool for protecting state interests and citizens’ personal data.
