Best-in-class OT security services to enhance uptime, safety and resiliency by helping you identify, track and remediate risk across your OT Infrastructure.
So you have already assessed your Operational Technology (OT) security posture and identified your risks. You may have already identified all your OT assets, including the connectivity associated with them, and now need to build a defensible network. Whether you’ve used our consultancy services or not, we can sit and work with your team to conduct an architectural review in order to determine your existing capabilities and give you a comprehensive, step-by-step roadmap to secure your OT environment.
Whether you’re building your industrial DMZ, creating security zones and conduits, or migrating to a zero-trust micro-segmentation strategy, OTIFYD has you covered.
As the world becomes increasingly interconnected, the need for robust security in critical infrastructure and industrial control systems (ICS) has become more pressing. Industrial cybersecurity is a field dedicated to protecting these systems from cyber threats, and it involves a range of security tools and practices.
One important concept in industrial cybersecurity is the “single pane of glass,” which refers to a unified interface for managing security across all devices and systems. This approach enables security teams to gain real-time visibility into their network and respond quickly to any security incidents.
OT devices, or operational technology devices, are a key component of industrial networks, and they require specialized security measures. Unlike traditional network devices, which are primarily designed for communication, OT devices are responsible for controlling physical processes, such as machinery and industrial equipment. This means that any security breach in an OT device can have serious real-world consequences.
To protect these devices and the larger industrial network, a range of security tools are employed, including firewalls, intrusion detection systems, and antivirus software. However, it is not enough to simply implement these tools and hope for the best – ongoing monitoring and proactive threat hunting are essential for maintaining a secure industrial network.
The rise of IoT devices has added another layer of complexity to industrial cybersecurity. These devices, which are often small and easy to deploy, can create new entry points for attackers. Industrial networks must carefully manage IoT devices to ensure they are properly secured and monitored.
OTIFYD provides turnkey Operational Technology (OT) consultancy and engineering services – from the design of new systems and upgrades to security assessment, remediation and network segmentation to ongoing managed security and reliability services. Our comprehensive consultancy services have been tailored to cover a wide range of client needs and include:
Our consultancy services are geared toward providing pragmatic “outcome-focused” improvement and risk reduction. This approach helps organisations justify OT cyber security improvements and the associated costs by being armed with better information and understanding of the “What, Why and How?”
Finally, our consultancy services draw heavily upon industry best practices and standards/frameworks such as ISO/IEC 62443, ISO/IEC 27001, and ISF but can also be tailored to your specific needs.
Firewalls are a ubiquitous part of Information Technology (IT) and Information Security (InfoSec), especially in situations where only one security measure is chosen.
Firewalls secure systems and data by monitoring and controlling the flow of traffic in, out and between networks using defined firewall rules (also known as policies) that filters traffic appropriately. This is true for both enterprise IT and industrial OT firewalls, which are normally used within OT/ICS environments.
Anomaly Detection is an innovative method for IT and OT security.
Unlike common security solutions, anomaly detection is not limited to detecting known threats or working along a generalised “allow-list”. The primary aim of this solution is to detect any anomaly in a network. An anomaly can be defined as any change in the specific established standard communication of a network. An anomaly may include both malware and cyberattacks, as well as faulty data packets and communication changes caused by network problems, capacity bottlenecks, or equipment failures.
Thus, anomaly detection enables holistic malfunction prevention, secures productivity and guarantees complete digital transparency.
OT Endpoint Protection is a necessity to protect the world’s OT infrastructure, but in many cases, it is not deployed due to several key challenges.
Endpoint protection is a foundational element in every industrial/OT cybersecurity strategy. Despite the known limitations, most industrial companies still use anti-malware and anti virus software wherever possible in their OT environments. Some also use application “allow-listing” solutions to further protect assets.
Automation vendors are likewise applying these security products as part of their standard reference architectures. Endpoint protection solutions used in industrial/OT systems are generally the same as those used for corporate IT. However, there are constraints on the products that are applicable for use in industrial control systems because users have unique challenges in maintaining malware signatures, etc. These differences impact the features industrial users want and the value they place on the new developments occurring in the endpoint protection market.
Unidirectional gateways are a combination of hardware and software, generally an appliance that allows data to travel in only a single direction, also known as data diode or diode firewall.
OT/Industrial Control Systems typically benefit from data diodes where secure historian replication is required, emulating protocol servers and devices (e.g. data feed to a simulator or digital twin) or simply for unidirectional file sharing.
Although sometimes referred to as a unidirectional firewall, technically they are not a firewall, they do not route traffic and they do not replace firewalls.
Active defence remains one of the most accurate methods to detect the presence of adversaries and malicious activities in your network.
The honeypot serves as a decoy, distracting cybercriminals from actual targets. It can also serve as a reconnaissance tool, using their intrusion attempts to assess the adversary’s techniques, capabilities and sophistication.
Modern deception defences use breadcrumbs as lures as decoys to make deception deterministic and more effective. Knowing attackers desire access credentials and information to learn and expand within an environment, these elements make perfect lures or bait leading to decoys or honeypots.
Security defences make too much noise, however, deception defences are pretty quiet in comparison to well-known security defences.
When it comes to internal blue teams being tested by external red teams for security preparedness, deception defences prove their value quickly for blue teams.
Sandboxing helps run a safe, isolated environment to test code, analyse files, updates and patches for malware and compatibility. Industrial sandbox confines a file/program/script to a test environment, preventing it from infecting or harming the host device or operating system.
As the name implies, this confined test environment functions as something like a “sandbox,” in which you can experiment with various variables to see how the system works or behaves. It is also a secure environment where anything that goes wrong cannot directly hurt your host machines or production environment.
Some of the benefits of OT sandbox are:
OT remote access allows users to access the hardware and software that controls industrial equipment without being on-premises. Whether they’re working from home or at another location within the company, remote access enables employees to adjust processes, update software, troubleshoot problems or perform other tasks necessary to maintaining business operations.
When defined in broad strokes, it’s a simple concept. But in practice, it is a complex undertaking that introduces risks to the enterprise via OT systems—many of which lack cybersecurity protections.
In today’s threat landscape, remote access is (or should be) inseparable from secure remote access.
