Cybersecurity Architecture Design and Implementation
A crucial aspect before design and implementation of appropriate cybersecurity architecture is a thorough analysis of current architecture and weak points identification
Contextual
including the position of Security and its role in Business
Conceptual
containing a high-level description of Security - Security Strategy
Logical
containing a model of organization model of information flow and Security Policy
Physical
describing the procedures, mechanisms, platform and network infrastructure
Component
consisting of direct utility to implement Security - standards, protocols, certificates
Operations
also called service management layer security – bounds other layers in daily operations of the organization - Safety of applications, networks, technical support
Goal
- Safety – situation where disruption of BPCS / DCS or SIS systems may cause harmful impact on humans and environment.
- Availability – situations where the implemented solution will not be possible to use on-demand, within the prescribed time, or its performance fails to meet the business requirements.
- Integrity of information – situations where data will be unauthorized or accidental modified, this also applies to the protection of data transmission between systems
- Confidentiality of information – situations where the collected data will be available to an unauthorized person
- Implementation and maintenance of security mechanisms can not generate costs that are not economically justified
- Security mechanisms can not unduly restrict the operations of the company.
Benefits of the security architecture implementation
- Business justification of implemented security mechanisms.
- Comprehensive and coherent approach to security.
- Tailored Security Architecture.
- Safety as a factor supporting, rather than disturbing to business organization activity.
- Possibility of integrating the most important standards, services and security solutions within a coherent security architecture.
- The developed concept is neutral in terms of choice of security solution provider.
- The developed solution is scalable.

Preventive Maintenance Won’t Solve Your Reliability Problems
There is a great deal that can be done to improve reliability outside of preventive maintenance. Some of it involves the maintenance department, and some of it does not.
