PLANNING · IT SECURITY
Planning IT security. Secure by design
Secure IT starts with a well-designed architecture. High Knowledge plans network zones, access rights, administration paths and recovery together – for enterprise IT, data centres and sovereign AI. Your protection needs become a practical security concept connecting technology, organisation and operations.
IT security concepts with clear priorities
Which information and services are essential to your business? What would an outage, unauthorised access or manipulated data mean for you? These questions define the starting point for IT security planning. We identify systems, data flows, responsibilities and dependencies, then agree your protection needs.
Existing policies, network diagrams and risk assessments inform the work alongside new projects. We derive prioritised measures and traceable architecture decisions. The security concept should support your operations and fit your resources, applications and planned changes.
Network segmentation and secure access
We plan separation between office IT, server services, management networks, building systems and external connections based on required communication. A zone and communication model describes permitted connections and suitable control points. Remote access, supplier access and privileged accounts receive particular attention.
Identities, multi-factor authentication and permissions belong in the same design. Access follows actual need; approvals, changes and revocation must remain manageable in daily operations.
Design for availability and recovery
IT security also protects operational continuity. We consider backup, recovery, logging and alerting together with the infrastructure. Recovery objectives must suit the applications and be verifiable through appropriate tests.
For data centres and critical IT infrastructure, we connect digital safeguards with physical dependencies: access, power, cooling and technical monitoring. Redundancy alone cannot replace a recovery concept or clear responsibilities during an incident.
Connect ISO 27001 and BSI IT-Grundschutz
An information security management system based on ISO/IEC 27001 provides the organisational framework for managing information risks. BSI IT-Grundschutz provides a methodology and specific requirements for security design. We align technical planning with your existing or planned ISMS.
Scope, protection needs and evidence are clarified early. A technical concept does not replace certification; certification, in turn, does not replace checking the actual technical implementation.
Penetration tests to assess effectiveness
With Penetration testing selected attack paths can be examined under agreed conditions. We consider scope, authorisation, operational risks and remediation during planning. Findings are prioritised; a retest can verify the implementation of corrections.
Integrate sovereign AI securely
Locally operated AI also needs a security concept. We consider data sources, access to the knowledge base, interfaces and AI agent permissions. Approved actions, protected credentials and traceable logs are particularly important. Running AI in your own data centre does not remove these requirements.
AI-assisted security tools can support event analysis. Suitability depends on data quality, false positives, privacy and integration into your processes. Responsibility for assessment and response remains clearly assigned.
From design to live operations
We plan changes in practical stages, including dependencies, maintenance windows, rollback paths and agreed acceptance criteria. This includes documented configurations, responsibilities and handover to your team. IT infrastructure planning provides the technical foundation; security measures become part of the target architecture.
What the planning delivers
Depending on the agreed scope, deliverables include an inventory and protection-needs overview, a zone and communication model, a role and access concept, and a prioritised action plan. We also define requirements for logging, recovery and technical testing.
This creates a sound basis for procurement, implementation and operations. Current network diagrams, key application details, existing security policies and known weaknesses help us get started.
Frequently asked questions
Is IT security planning useful for smaller businesses?
Yes. Business dependencies and protection needs matter more than company size alone. The scope is tailored to your IT, risks and resources.
Does a penetration test replace a security concept?
No. A penetration test examines an agreed scope at a particular point in time. The security concept defines architecture, measures and responsibilities. The two complement each other.
Can we continue using an existing ISMS?
Yes. Existing policies, risk assessments and evidence provide the starting point. We assess how the planned IT architecture fits and which additions are needed.
