Telemetry data reveals the heightened risks of IoT and OT networks due to sophisticated attacks and a surge in vulnerabilities. Nozomi Networks’ analysis of 2023 data highlights a spike in threats, signaling a shift towards more sophisticated cyberattack methods. However, cyberattacks on IoT devices saw a 12% decrease. The increase in vulnerabilities and sophisticated tactics underscores the need for a resilient cyber defense approach, emphasizing post-breach strategies and actionable threat intelligence.
Key takeaways from the meeting notes are as follows:
1. The new telemetry data highlights the increased risks associated with IoT and OT installations due to the growing number of vulnerabilities and sophisticated attacks targeting these networks.
2. Nozomi Networks’ analysis revealed that network anomalies and attacks, such as TCP flood and network scans, were the most prevalent threats to IoT and OT networks.
3. The data suggests that attackers are adopting more sophisticated methods to target critical infrastructure, indicating rising global hostilities.
4. Traditional cyberattack approaches like access control and authorization threats, including brute force and multiple login attacks, also saw a significant increase.
5. While there was a 12% decrease in daily cyberattacks against IoT devices during the last half of 2023, the number of vulnerabilities affecting industrial control systems (ICS) and impacted vendors rose significantly.
6. Chris Grove emphasized the importance of not only focusing on security defenses but also adopting a post-breach mentality to minimize risks and maximize operational resiliency.
7. Strategies such as network segmentation, asset discovery, vulnerability management, patching, logging, endpoint detection, and threat intelligence should be prioritized to enhance cyber defense and resiliency.
These takeaways provide insights into the evolving cybersecurity landscape and emphasize the need for organizations to adapt their defense strategies to effectively mitigate the growing risks associated with IoT and OT networks.
