Cybersecurity
At HSB Solutions, we help our clients by providing aerospace cybersecurity engineering services to protect safety-critical systems against cyber threats. Our approach integrates cybersecurity considerations into system architecture, safety, and certification activities ensuring that security risks are addressed without compromising safety, performance, or certifiability.
We support programs from early concept through certification and continued operational support.
What We Do in Cyber Security:
Threat Modeling & Risk Assessments
We perform structured airworthiness security risk assessments to identify and manage cybersecurity threats throughout the system lifecycle. Our approach is aligned with ED-202B and ED-203A and focuses on protecting safety-critical functions from cyber interference.
Key activities include:
-
Identification of system assets, external interfaces, and connectivity pathways
-
Analysis of potential attack Points/Interfaces across aircraft, ground, and maintenance environments
-
Threat identification considering intent, capability, and access vectors
-
Assessment of potential safety, operational, and certification impact
Threat modeling outputs are fully traceable to system architecture, safety analyses, and security requirements, enabling consistent and defensible certification evidence.
Secure Design of Safety-Critical Systems
We support the secure-by-design development of aerospace systems by embedding cybersecurity considerations into system architecture from the earliest design phases. Our focus is on ensuring that security mechanisms are appropriate, certifiable, and compatible with safety objectives.
Key activities include:
-
Security-aware system and interface architecture definition
-
Segregation and partitioning strategies to protect safety-critical functions
-
Secure data flows, access control, and interface protection mechanisms
-
Alignment between cybersecurity controls, system safety requirements, and security assurance levels
Our approach ensures cybersecurity measures enhance overall system robustness without introducing unintended safety or certification risks.
Cybersecurity Certification Planning & Support
We support customers in planning and executing cybersecurity certification activities, ensuring compliance expectations are clearly defined and supported by objective evidence. Our services help translate regulatory guidance into practical, program-specific certification strategies.
Key activities include:
-
Development of cybersecurity plans aligned with ED-202B objectives
-
Definition of compliance strategies and means of compliance
-
Traceability between threats, security requirements, mitigations, and verification evidence
-
Support during certification reviews, audits, and authority interactions
-
Resolution of cybersecurity-related findings and observations
Our goal is to ensure cybersecurity evidence is clear, traceable, and defensible, enabling smooth certification and regulatory approval.
