Cybersecurity consulting and audit services for Building Management System (BMS) is a service for protection and security of systems that manage critical building infrastructures. These systems, known as Building Management Systems (BMS) or Building Automation Systems (BAS), provide automated control of technical systems in buildings, such as lighting, heating, ventilation, air conditioning (HVAC), security systems, access systems and water management systems.
Due to their integration with IT networks and OT/IoT infrastructure of buildings, these systems are increasingly exposed to cyber threats. Cyberattacks on BMS can have serious consequences, from disrupting the operation of buildings to endangering the physical safety of people.

Objectives of the service

• Protection of BMS systems: Security assessment of control systems and thereby prevent unauthorized access or manipulation of technical devices in the building
• Maintaining Business Continuity: Security assessment of ensuring continuous operation of critical technical equipment such as HVAC, lighting and security without cyber disruptions
• Threat and Incident Detection: Security assessment of capabilities to monitor and detect cyber threats and anomalies in BMS networks in real time
• Incident response and recovery after an attack: Security assessment whether a process can be implemented for rapid response and recovery of systems in the event of a cyber incident

Main components of the service

• 1. BMS security and vulnerability assessment

  • Cyber security audit: Evaluation of current security measures and identification of weaknesses within BMS systems and their integration with IT networks
  • Vulnerability testing: Performing penetration tests and simulated attacks on the BMS infrastructure to identify possible attack paths and vulnerabilities

• 2. Protection of BMS systems

  • Review of security of access rights: Review and implementation of policies to control access to BMS devices, including role-based access control (RBAC), strong passwords and two-factor authentication (2FA)
  • Network encryption and segmentation review: Data encryption review (BacNet/SC) and BMS network segmentation analysis to minimize the possibility of cyber threats penetrating from the IT network to the OT network
  • Malware and attack protection review: Assessment of security tools that protect against malware, ransomware and unauthorized access to BMS systems

• 3. Monitoring and detection of threats

  • Implementation of anomaly detection systems: Deploying tools for monitoring and detecting anomalies in the operation of BMS networks (OT IDS) that may indicate a cyber-attack or misuse

• 4. Incident Response and forensic analysis

  • Forensic analysis: Performing a detailed analysis of cyber-attacks on BMS systems in order to determine the origin of the attack, identify compromised systems and create a recovery plan
  • Systems recovery: Advice on implementing security measures to prevent future attacks

• 5. Increasing resistance to threats

  • Staff training and awareness: Training technical and security teams on cyber threats and best practices for managing BMS systems
  • Regular updates and patches: Checking that all BMS systems are regularly updated and equipped with the latest security patches
  • Verification and testing of response plans: Checking regular exercises and simulations of cyber incidents to test the preparedness of teams to deal with incidents

• 6. Continuity of operation and disaster recovery

  • Review of backup and recovery: Review of the process of regular backup of BMS systems and preparation of plans for their recovery in case of failure or cyber-attack
  • Reviewing incident recovery plans: Assessment of incident recovery plans to minimize downtime and quickly restore systems operations

Advantages of the Cybersecurity service for BMS

• Prevention and protection of critical systems: Ensuring cyber protection and safety for systems that control key building infrastructures such as HVAC, lighting, access systems and security systems
• Minimizing the risk of attacks: Preventive measures aimed at minimizing the risk of cyber-attacks that may threaten the security of the building or the comfort of its occupants
• Improving security preparedness: Improving security processes, training employees and regularly testing preparedness for cyber incidents
• Maintaining business continuity: Ensuring continuous operation of buildings even in the event of a cyber incident, including rapid response and recovery of systems

Our Cyber Security Assessment for Building Management Systems (BMS) service provides organizations with comprehensive protection of their automated systems, ensuring reliable building operations, minimizing the risk of cyber attacks and helping to protect both physical and cyber infrastructure
