Her perspective connects security domains that do not operate independently in real systems: communications networks, cloud access, identity, detection, response and the controlled use of AI.
Telecommunications and 5G/O-RAN as a distributed security domain
Maryam Bück describes her background as spanning telecommunications and 5G/O-RAN. This wording was supplied by her for this profile; without further publicly verifiable project detail, VENTEX does not infer a particular employer role, deployment record or responsibility for a specific network.
This technical background is also supported by a 2025 certificate covering 5G O-RAN architecture, procedures and use cases.
The perspective is relevant because modern mobile architectures combine control, management and data planes with virtualised components, APIs and distributed operational ownership. Security therefore has to address not only individual components but also transitions, identities, telemetry and response capacity across the full lifecycle.
Cloud security and identity as one control surface
The project documented in her CV as the “Azure Security Hardening Project” (01/2026–03/2026) describes the hardening of an intentionally insecure FastAPI deployment in Azure. It names Microsoft Entra ID, oauth2-proxy, Nginx, HTTPS/TLS, a more isolated PostgreSQL connection, rate limiting and ModSecurity.
Architecture, controls and validation are documented separately: anonymous, invalidly authenticated and authorised access were checked against expected 401, 403 and 200 responses. The public repository is deliberately sanitised and does not include the full source set; it demonstrates traceable learning and implementation work, not an independently assessed production platform.
SOC, IAM and accountable response
This corresponds to her professional experience at Cybersteps Germany (05/2025–06/2026, SOC/SIEM focus, 1,800 hours), including work with Microsoft Sentinel, Splunk and QRadar as well as Entra ID, Conditional Access, MFA and RBAC following zero-trust principles.
SOC/SIEM and Identity and Access Management belong together in connected security architectures: identity determines who may act; telemetry and detection show whether controls work or are being bypassed; incident processes translate signals into accountable response.
The VENTEX profile does not turn those public focus areas into a claim about a particular job or responsibility for another organisation’s security operations centre. It records the perspective Maryam Bück brings personally to the mission.
AI security between usefulness and control
Her approach to AI-security questions is additionally supported by the CompTIA SecAI+ certification (2026).
In the public “Juni / SafeChatGPT” project, Maryam Bück explores controlled access to AI functions for children. The repository describes input and output checks, Allow, Rewrite, Block and Escalate decisions, a PIN-protected guardian dashboard, rate limiting and traceable safety logging.
The project expressly describes its feature set as a proof of concept and documents limitations of its own. That distinction matters here: AI security does not come from a blanket claim, but from named protection decisions, observable behaviour, bounded trust assumptions and reviewable residual risk.
Why her perspective matters to the mission
VENTEX pursues a broader mission to develop secure communication and resilient digital infrastructure with technical precision, controllability and verifiability. Modern systems rarely fail because of one component alone; risk often accumulates at the boundaries between network, device, identity, cloud service and operational response.
Maryam Bück’s requested positioning across telecoms and 5G/O-RAN, cloud and AI security, SOC/SIEM and IAM brings that connective view to the mission. It is a personal perspective and not an assessment of the security, cryptography or product maturity of VENTEX Connect.
Her current certification portfolio (Microsoft SC-300, AZ-500, AZ-900; CompTIA Security+, CySA+, Network+, SecAI+, Tech+; PECB ISO/IEC 27001 Lead Implementer; 5G O-RAN) supports this self-description but – as emphasised elsewhere in this profile – does not replace an independent review or certification of VENTEX Connect.
Her role as a Mission Supporter
Maryam Bück personally supports the broader VENTEX mission. The role is intentionally lightweight and includes no required tasks, meetings, reviews, financial contributions or continuing work.
It does not constitute a technical review, certification, product approval, formal advice or institutional support. Maryam Bück retains control over the text, presentation and scope of her public representation.
