Government, Defence and Public Security
Government and ministerial bodies, defence and public security: protection of sensitive data and information within the mandate and authorization.
DATA SECURITY ARCHITECT
Sovereignty and control
of information
I’m Gianfabio Chianura, a Data Security Architect.
I protect the continued existence, confidentiality and sovereignty of critical data and information for exposed individuals and organizations, through architecture, permissions and cryptography that reduce exposure to unauthorized parties.
- Data under your control
- Confidential information
- Less exposure to third parties
- Preserved and recoverable data
01 / PROFILE
Restore control
and ensure security and availability
I work with information whose exposure can affect personal autonomy, economic interests or institutional responsibilities. My practice combines exposure assessment, high-security design and verification of safeguards.
Over ten years of Linux infrastructure, network and digital-environment experience support consulting focused on data, archives, copies and keys. I define system-level access capabilities through policies, permissions, ACLs and ownership. I have served and continue to serve as a party-appointed technical consultant in civil and criminal proceedings on technical IT data-security matters.
02 / EXPERTISE
Expertise in designing
and verifying protection.
Information and assurance
Sovereignty threats, cryptography and technical forensic analysis.
- 01Threat Modeling and Threat Analysis
- Analysis of threats to data and information sovereignty and confidentiality. Modeling of actors, capabilities, interests and exposure or compromise paths, with assessment of third-party dependencies and protection requirements for each engagement.
- 02Data and Communication Cryptography
- Protection of transmissions and communications through cryptography and of data and files through encryption. Design using symmetric and asymmetric encryption, key management, digital signatures and PGP/GPG, retaining control of decryption capabilities.
- 03Security Assurance and Technical Forensic Reviews
- Verification of implemented protection measures and consistency between requirements, configurations and expected outcomes. Technical forensic analysis of evidence relevant to data security, with documented findings and party-appointed technical consulting in civil and criminal proceedings.
02 / EXPERTISE
Data and continuity
Filesystems, backups and Linux system high availability.
- 04File System Security & Access Control
- Protection of files, directories and archives through filesystem permissions, ACLs, ownership and volume separation. Definition of system-level read, write and deletion policies aligned with operational responsibilities and key availability, without IAM or application authorization management.
- 05Data Resilience and Recovery Architecture
- Design of backups, protected copies, data redundancy and restoration paths to preserve information existence, integrity and recoverability. Separation of copies, keys and recovery domains, with restoration verification following failures, deletion or compromise.
- 06Linux Server High Availability and Redundancy
- Design of HA and redundancy architectures for Linux server systems. Separation of failure domains and definition of continuity and recovery paths for critical environments and regulated sectors, distinguishing service availability from data recoverability.
02 / EXPERTISE
Infrastructure and streams
Hardening, network segmentation and RTSP protection.
- 07Linux System Hardening and Protection
- Security configuration of Linux systems and exposed services, reducing attack surface and separating environments. Use of ModSecurity, fail2ban, nftables, UFW and infrastructure filtering and protection tools, aligned with data sensitivity and operational requirements.
- 08Network Segmentation, VPNs and VLANs
- Design of segmentation for business and private networks using VLANs, VPNs and communication policies between domains. Definition of authorized flows and network boundaries to separate services and devices, protect transmissions and contain compromise propagation.
- 09RTSP Stream and IP Surveillance Protection
- Protection of IP camera RTSP streams and transmission paths to NVRs and archives. Network segmentation and connection protection through encrypted channels or VPNs when the native protocol lacks adequate encryption, with system permissions and protected recording retention.
03 / OPERATING CONTEXTS
High-risk
operating contexts.
01
Government, defence and public security information
Government and ministerial bodies, defence organizations, public security agencies and professionals authorized to handle confidential operational information.
Disclosure, alteration or loss of documents and archives can expose operations, relationships and institutional responsibilities. Protection addresses data and copies through environment separation, system permissions and key control, within the mandate and authorization.
03 / OPERATING CONTEXTS
02
Confidential banking and financial operations
Banks, financial intermediaries, business leadership and professionals handling credit files, financial documents and confidential operations.
Dossiers, financial documents and communications may be disclosed, copied or made unavailable. Protection uses encryption, filesystem permissions and separate recovery paths for archives and copies, limiting dependence on administrators and suppliers.
03 / OPERATING CONTEXTS
03
Healthcare data processing and retention
Healthcare organizations, clinics, laboratories and professionals retaining medical records, reports, diagnostic images and healthcare archives.
Records, reports and images may be disclosed, altered or lost during retention, transfer and backup. Protection addresses confidentiality, integrity and recoverability of clinical data at system level, without changing permissions or roles in healthcare applications.
03 / OPERATING CONTEXTS
04
Corporate transactions and strategic research
Entrepreneurs, CEOs, executives, R&D leads and advisers involved in M&A, negotiations, changes of control and intellectual property development.
Advance knowledge of decisions, projects and negotiations can compromise economic interests and intellectual property. Protection uses encryption, environment separation and system permissions for documents, archives and copies, aligned with confidentiality needs.
03 / OPERATING CONTEXTS
05
Data retention with providers and vendors
Businesses, professionals and organizations entrusting archives, copies and infrastructure to cloud providers, hosting companies, manufacturers or external suppliers.
Providers and administrators may retain capabilities to read, decrypt, copy or delete data; failures and dependencies may prevent recovery. These capabilities are assessed and necessary trust reduced through key control, independent copies and storage architecture.
03 / OPERATING CONTEXTS
06
Surveillance of sensitive locations and exposed individuals
Journalists, activists, prominent individuals, CEOs, executives and organizations using IP cameras and NVRs in homes, offices or sensitive locations.
Streams and recordings can reveal presence, routines, meetings and relationships; unprotected copies amplify exposure. Protection covers video streams and archives through segmentation, protected connections, system permissions and retention policies, assessing residual cloud and manufacturer capabilities.
03 / OPERATING CONTEXTS
07
Investigative journalism and source handling
Investigative journalists, newsrooms and organizations retaining disclosures, documents, communications and materials linked to sensitive sources.
Documents, metadata and copies can identify sources or reconstruct relationships; material loss may undermine the work. Protection covers archives and communications through encryption, copy separation and system-level control of permissions and keys.
03 / OPERATING CONTEXTS
08
Personal and financial confidentiality
HNWIs, families, family offices, executives and professionals retaining personal documents, financial information and confidential communications.
Documents and copies can expose relationships, assets and personal interests or be lost. Protection addresses retention and confidentiality through encryption, system permissions and recovery paths, limiting disclosure to collaborators and providers.
03 / OPERATING CONTEXTS
09
Civil and criminal litigation
Law firms, parties in proceedings, party-appointed technical consultants and professionals handling files, confidential documents and technical IT evidence.
Case files and evidence may be disclosed, altered or lost; declared safeguards may differ from implemented measures. Protection addresses the materials and, under a CTP mandate, examines configurations and evidence relevant to the assigned question. Findings remain proportionate to available materials.
