What is IoT?

As industrial digital transformation happens, it´s more necessary to connect to the IT systems and the internet for data sharing and controlling the Plant.

Industries like healthcare, Automobiles, Energy, Pharmaceuticals, and Manufacturing use systems like sensors, Supervisory Control and Data Acquisition (SCADA), smart meters, Human Machine Interface (HMI), Remote Terminal Units (RTU), Distributed control systems (DCS) that need to share data and communicate with each other and to the IT systems.

Internet of Things, in simple terms, are the objects embedded with sensors and software to share and exchange data among the systems and over the internet. Why do we need to protect Industrial IOT Systems?

As the OT environment connects to the IT system and the internet, the threat landscape increases, and it lures more cybercriminals. Hence, it needs proactive measures to protect the environment from criminals. The most common security flaw that we find in the OT environment is the wide usage of legacy systems, software, or protocols which doesn´t come with any security. Most attacks on the ICS network are often targeted attacks. One of the state-sponsored attacks against the IRAN nuclear program Stuxnet, which uses worms to manipulate the centrifuge of the nuclear power plant. These kinds of attacks bring more damage to the environment, Humans and bring a bad reputation for the Nation. Most of these kinds of attacks focus on data theft and/or espionage.

Some of the critical challenges that the IoT or Industrial systems faces are:

• Unauthorized access to the systems or code
• Poor testing
• Unpatched vulnerabilities
• Weak or no passwords
• Lack of visibility

Insoft helps in Securing the Industrial IoT systems and the environment by adopting several techniques or methods followed by us, and among all some of them are listed below:

• Make sure vulnerabilities are patched regularly
• Usage of strong passwords on each endpoint or device
• Strong authentication and encryption
• Defense-in-depth approach
• Device Discovery to have complete visibility of the IoT devices
