Cybersecurity Industrial Control Systems Services

The Cybersecurity Industrial Control Systems Services provides guidance on how to secure Industrial Control Systems, including Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), and other control system configurations such as Programmable Logic Controllers (PLC), while addressing their unique performance, reliability, and safety requirements.

Our services provide an overview of ICS and typical system topologies, identifies typical threats and vulnerabilities to these systems, and provides recommended security countermeasures to mitigate the associated risks.


ICS implementation includes the following features:

  • Restricting logical access to the ICS network and network activity. This may include using unidirectional gateways, a demilitarized zone (DMZ) network architecture with firewalls to prevent network traffic from passing directly between the corporate and ICS networks, and provide separate authentication mechanisms and credentials for users of the corporate and ICS networks.

  • Restricting physical access to the ICS network and devices. Unauthorized physical access to components could cause serious disruption of the ICS’s functionality. A combination of physical access controls should be used, such as locks, card readers, and/or guards.

  • Protecting individual ICS components from exploitation. This includes deploying security patches in as expeditious a manner as possible, after testing them under field conditions; disabling all unused ports and services and assuring that they remain disabled; restricting ICS user privileges to only those that are required for each person’s role; tracking and monitoring audit trails; and using security controls such as antivirus software and file integrity checking software where technically feasible to prevent, deter, detect, and mitigate malware.

  • Restricting unauthorized modification of data. This includes data that is in transit (at least across the network boundaries) and at rest.

  • Detecting security events and incidents. Detecting security events, which have not yet escalated into incidents, can help defenders break the attack chain before attackers attain their objectives. This includes the capability to detect failed ICS components, unavailable services, and exhausted resources that are important to provide proper and safe functioning of the ICS.

  • Maintaining functionality during adverse conditions. This involves designing the ICS so that each critical component has a redundant counterpart. Additionally, if a component fails, it should fail in a manner that does not generate unnecessary traffic on the ICS or other networks, or does not cause another problem elsewhere, such as a cascading event.

  • Restoring the system after an incident. Incidents are inevitable and an incident response plan is essential. A major characteristic of a good security program is how quickly the system can be recovered after an incident has occurred.

  • Cybersecurity operational services. We perform the following activities:
    • Segregation and segmentation
    • User access control management
    • Patch frequently
    • Run validation checks
    • Add physical security
    • Train personnel on how to identify attacks, how to protect their personally identifiable information, and how to secure themselves against attacks
    • Create an incident response plan
    • Maintain an updated asset register

Added Value

Starting a cybersecurity initiative for industrial systems isn’t as daunting a task or as big an investment as it might appear at first. The trade-off in preventing the amount of possible damage makes it ridiculous for companies to not consider investing in cybersecurity.

Cybersecurity needs to be a plant-wide initiative. We implement it, through five phases:

Phase 1: Design and framework
Designing a cybersecurity management system is the most comprehensive phase and requires the most investment in time and effort from both our and customer side. In this task, we include identifying all systems and personnel linked to cybersecurity, defining their roles, defining their access and control rights, and building policies around these parameters to ensure safe operations.

Phase 2: Gap assessment
Our assessment phase primarily consists of reviewing the cybersecurity design and identifying potential vulnerabilities and risks depending on business impact. Identified gaps are addressed and updated in the design. Assessments are performed, using our experienced personnel and various tools that will sniff the network level packets and identify anomalous behavior and gaps in system hardening.

Phase 3: Implementation
This part is where we implement cybersecurity policies, procedures, and practices, ensuring that all checklists are marked. A key method of implementation is system hardening.

Phase 4: Audit
Auditing cybersecurity covers tasks like comprehensive penetration testing to ensure that the cybersecurity implementation is achieving desired results. Out specialized pentest & audit team usually tackle this job and help ensure solid cybersecurity. However, we can deliver training to internal cybersecurity audit team to perform all phases. That team can use its learning and expertise to audit other plants and facilities within the organization.

Phase 5: support and maintenance
To guarantee a determined level of compliance, it will be necessary to ensure the maintenance and support of the effort that was initially made. We create value in ensuring infrastructure management, control, and monitoring, in order to keep cybersecurity controls in all entire infrastructure.

The Service is available in the following options:

  • Audit the current security status.
  • Prepare for accreditation or re-accreditation security process.
  • Maintain security standards compliance.
