IoT Security

IoT, one of the largest and most popular technologies of recent years, is in high demand in improving operational efficiency. However, with the rise of IoT and connected devices, it brings cyber attacks. Many IoT devices communicate insecure and contain sensitive information on their devices or systems in the cloud. Moreover, most of these systems are protected by weak password policies. In addition, the input panels can accommodate weaknesses. In fact, OWASP has a list of top 10 IoT vulnerabilities. At the top of this list is the weaknesses on the interfaces used.

The rapidly developing technologies, the lack of standards and legislation, the use of commercial technology in business and industry constitute IoT’s security complex. To address this challenge, organizations need to provide security for their products and services. Companies, by using the communication protocols used by the devices in an encrypted way, actually provide a click security on IoT devices. We are working on an in-depth study of cyber threats and security vulnerabilities for IoT technology.

We determine the weaknesses and prepare a detailed report on this subject so that you can make the IoT devices used by your company more secure. Our services support you in this respect and examine your connected solutions at the physical, communication and software levels, including:

  • Embedded Systems: Devices that collect data and interact with the world,
  • Firmware: Software running on built-in devices,
  • Wired / Wireless Communication: Protocols connecting devices, IP gateways and remote systems,
  • Supporting Infrastructure: Routers, switches and data collectors,
  • Cloud Services: Remote servers that manage data and control devices,
  • Applications: End-user applications that provide access to data or control devices.

In this context, we work to ensure the sustainability of cyber security by enabling our customers to identify and protect risks.

IoT Security Services

  • IoT security health check: A quick, practical risk assessment for your end-to-end IoT system. Our health control includes privacy, compromise and abuse, reliability and availability, data integrity, non-rejection of software, verification of firmware updates, and scalability.
  • Developing secure architecture for IoT: An end-to-end approach that provides an IoT architecture that must be secure at the design stage. We define the necessary technical security controls and incorporate them into the architecture as well as business-related controls such as response to events, business continuity and confidentiality.
  • Expert security testing phase: Cyber ​​security assessments tailored to your IoT ecosystem. We help find vulnerabilities before cyber attacks.
  • Confidentiality and data protection process: Studies on data protection and confidentiality of IoT devices. Our experts working on data privacy help ensure that your IoT systems protect personal information. This includes privacy impact assessments, information protection, privacy frameworks, and regulatory and regulatory compliance (GDPR).

Frequently Asked Questions About IoT Security

Why Should I Use IoT (Internet of Things) Security Service?2020-03-07T15:05:19+03:00

IoT involves adding an internet connection to related computer devices, mechanical and digital machines, objects, animals and people. Each “thing” has a unique identifier and allows you to automatically transfer data over a network. Allowing devices to connect to the Internet can cause a number of serious security vulnerabilities if they are not properly protected.

IoT security has been the subject of review after a series of high-profile events using a common IoT device to infiltrate and attack a larger network. Implementing security measures is critical to securing networks with IoT devices connected to them.

What Are the Challenges of IoT Security?2020-03-07T15:05:07+03:00

Numerous challenges prevent the security of IoT devices and end-to-end security in the IoT environment. Because the idea of ​​networking tools and other objects is relatively new, security is not always considered a top priority in the design phase of a product. In addition, since IoT is a developing market, many product designers and manufacturers are more interested in marketing their products rather than taking the necessary steps to ensure safety.

A major problem with IoT security is the use of hard-coded or default passwords that could lead to security breaches. Even if passwords are changed, they are not strong enough to prevent leakage. Many devices do not offer advanced security features. For example, sensors that monitor humidity or temperature cannot meet advanced encryption or other security measures. In addition, many IoT devices receive virtually no security updates or patches with the idea of ​​“set and forget”.

From the manufacturer’s point of view, providing security from the very beginning can be expensive, slow down development, and cause the device to malfunction.

Can You Give Examples of Important IoT Security Breaches and IoT Attacks?2020-03-07T15:04:51+03:00

A series of attacks took place in various media, from refrigerators and TVs used to send spam, to hackers who infiltrated baby monitors and tried to talk to children. It should be noted that most IoT attacks do not target the devices themselves, but rather use IoT devices as the entry point to the network.

For example, in 2010, researchers found that the Stuxnet virus was used to physically damage centrifuges in Iran, with attacks starting in 2006 being the primary attack in 2009. Stuxnet virus, generally regarded as one of the oldest examples of IoT attack, uses malware to infect instructions sent by programmable logic controllers (PLCs) by targeting centralized control and data acquisition (SCADA) systems in industrial control systems (ICS).

In December 2013, Proofpoint Inc.’s corporate security company researcher discovered the first IoT botnet. According to the researcher, more than 25% of botnet consisted of non-computer devices such as smart TVs, baby monitors and home appliances.

In 2015, security researchers Charlie Miller and Chris Valasek wirelessly attacked a Jeep, changed the radio station in the car’s media center, switched on the windscreen wipers and air conditioning, and stopped the accelerator pedal to operate. They said they could kill the engine, activate the brakes, and completely deactivate the brakes. Miller and Valasek were able to infiltrate the vehicle’s network via Urys, Chrysler’s in-car connection system.
