Security and IT professionals must be aware of the dangers and implement security measures targeted at reducing the impact of a future cyberattack and boosting the security posture of critical infrastructures.

Fremont, CA: Threat actors have routinely targeted firms in the energy, utility, and other industries in recent years. Cyberattacks on vital infrastructure have gotten more complex and disruptive, causing systems to go offline, disrupting operations, or simply allowing attackers to take control of the affected systems remotely. Cyberattacks on critical infrastructures have become cyber-warfare in the current geopolitical environment, as the ability to disrupt a country's critical infrastructure by shutting down power plants, disrupting oil pipelines, and even disrupting water and heating utilities can provide significant military advantages. Security technologies and best practices, on the other hand, can assist lessen the dangers associated with internet-connected industrial control systems, and the interruptions and impact an attack could have on a city or country.

IoT and Risk Exposure

Smart sensors and communication technologies integrated into diverse industrial control systems represent a threat to infrastructure and businesses. The higher the potential damage, the more smart gadgets that are hooked into and connected to critical infrastructure networks. If penetrated by threat actors, even one weak smart sensor connected to the internet can operate as a conduit for launching attacks or compromising other key systems on the same network. Indirect attacks on critical infrastructure are also possible. Threat actors frequently profile employees and infiltrate their home networks and endpoints in an attempt to obtain sensitive work-related data or gain access to vital infrastructures via compromised BYOD devices.

The danger of a successful cyberattack can be reduced by identifying vulnerabilities and getting visibility into the number of smart devices and their role within the infrastructure. As a result, it's necessary to retain a full inventory of all IoTs, check for new security upgrades that address known vulnerabilities on a regular basis and keep them on a separate network from other key systems.

Better visibility

Visibility throughout the entire infrastructure is essential for properly identifying attacks aimed at IoTs or OTs. Deploying real-time network monitoring systems that can notice odd behavior or even exploit attempts directed at specific devices is crucial for increasing an infrastructure's cyber resilience and operational reliability.

Security teams can swiftly identify and contain any threat that moves laterally throughout the infrastructure with consolidated visibility across various networks and even entire sites. This can also aid security and IT departments in developing a more proactive security posture. Through the use of actionable intelligence, visibility, threat intelligence, and advanced data analytics may assist in predicting danger and design comprehensive protection measures.
