Enhanced Security for IoT, OT, and ICS Deployments can be accomplished with device and network security testing, including breach and attack simulation.
Securing critical infrastructure, including ICS/OT and IIoT/IoT deployments, requires solutions that emulate cyberattacks to protect connected devices and the networks to which they are connected. Safety, uptime/continuity, and security are critical for organizations operating large fleets of mission-critical connected devices, such as manufacturing, complex global and regional operations, healthcare, and utilities.
Yes, device manufacturers are responsible for security fixes. However, these typically lag actual risks/attacks and zero days. Enterprises need time to take vulnerable devices offline or replace them before they are compromised. Often, these updates must be tested…and tested over time.
Our personal experience is that some of these updates can be mission affecting with negative results. Therefore, testing networks and devices against multi-stage attacks — including ransomware infections, lateral movement, phishing attempts, protocol fuzzing, and data exfiltration — is vital.
BLUF:
To harden IIoT/IoT devices, use a device security test tool to subject them to low-level protocol fuzzing and upper-layer application attacks. Thoroughly test chipsets and network stacks to find flaws in Ethernet, Wi-Fi®, Bluetooth®, Bluetooth® Low Energy, LoRa, CAN bus, and cellular interfaces.
Utilize specialized field and lab testing for OT devices that can ‘break’ if tested see our blogs on OT/ICS testing. At the same time, network security teams must continuously assess firewalls, endpoint security, and properly correlated SIEM/SOAR tools to prevent configuration drift and detect alerts.
Use a breach and attack simulation(s) tool(s) to emulate multi-stage network attacks, reveal gaps in coverage, and identify remediations. Without these, security tool updates can inadvertently cause blind spots or vulnerabilities.
Critical infrastructure and IIoT/IoT deployment security solutions require enterprises to secure critical OT/ICS/IIot/IoT deployments with both manual (RedTeam/PurpleTeam) and automated security testing and breach and attack simulation.
These ideally should emulate multi-stage cyberattacks with your teams, scan for vulnerabilities, and mitigate risk with a systematic and ever-expanding list of security assessments, audits, and test plans.
