IoT Security Threats and Solutions

IoT security is the defense of internet-connected devices, such as sensors, cameras, and controllers from cyberattacks. These products are frequently connected to the Internet of Things (IoT), which is a network of physical items implanted with electronics, software, and sensors that enable them to gather and share data.

The security of IoT devices is a growing issue as they become more prevalent. Many of these devices are not secure by default, and they often lack basic security features such as authentication and encryption. Due to this, the security of the devices and the data they gather may be compromised by attackers. According to a survey by Keyfactor, cyberattacks have cost 89% of respondents’ organizations that run IoT and connected products an average of $250K.

Several actions may be performed to increase the security of IoT devices. These include ensuring that devices are properly configured and updated, using security features such as authentication and encryption, and monitoring devices for suspicious activity.

IoT Security Threats

The vast majority of IoT threats are mundane and low-risk, but there are a few high-impact threats that could cause serious damage.

The possibility of hackers accessing sensitive information stored on IoT devices is one serious threat. This could include personal information (such as names, addresses, and passwords), financial information (such as bank account numbers and credit card numbers), or even sensitive military information (such as troop movements and strategic plans).

Another high-impact threat is the potential for rogue devices to be installed on corporate networks or government institutions. These devices might be used to break into some other systems and steal confidential information.

Finally, IoT devices can be exploited by hackers to launch cyberattacks on other systems. This could include accessing private information, stealing money or data, or attacking critical infrastructure systems.

IoT security threats come in a variety of forms, from simple password breaches to more sophisticated attacks that exploit vulnerabilities in IoT devices.

IoT security risks that are frequently observed include:

  1. In-vehicle security breaches: A recent study found that more than 50% of drivers in the US are at risk of being hacked, and many of these attacks happen without the driver even knowing it.
  2. Tampering with IoT devices: One of the most common ways to exploit IoT devices is to tamper with their firmware that can result in data being lost or corrupted.
  3. Data theft: Another common IoT security threat is data theft, which is often done to gain access to financial or personal information.
  4. Insecure internet connections: A lack of security standards can leave IoT devices open to attack, and this can include hacker attacks as well.
  5. Vulnerabilities in open-source IoT firmware: Many IoT devices are built with open-source firmware, which can be vulnerable to attacks.




IoT Security Solutions

There is no single solution that can protect all IoT devices from all types of threats. Below is the list of solutions that can help in protecting IoT devices:

  1. Physical Security: Physical security is essential for avoiding unwanted access to a device because IoT applications are frequently remote. Using durable parts and sophisticated hardware that makes accessing data more challenging is beneficial in this situation.
  2. Protection against remote access: A strong security mechanism for remote access is required that permits– SIM capability restricted to particular devices.- In the event of a physical security compromise, the capability to remotely terminate connections.
  3. Private networks: There is a security risk whenever messages are sent and received via remotely deployed devices. These messages are susceptible to interception when devices are connected, and communication is enabled over public-access networks like Wi-Fi.While using public networks to communicate sensitive data calls for additional care, encrypting messages is a good first step. Private networks guarantee that data never travels via the open Internet on top of the current security measures.
  4. Encryption: Protect data from unwanted access by encrypting it while it’s in transit and at rest. This covers safe data storage on devices and encryption of communication channels.
  5. Updates to the firmware and patch management: Update firmware frequently and install security patches to fix bugs and guard against exploits. This entails setting up procedures for timely patching and guaranteeing interoperability with IoT devices.
  6. Blockchain Techniques: The integration of blockchain technology improves the transparency and integrity of IoT data transfers. Distributed ledger technology strengthens trust and accountability by guaranteeing data immutability and offering a tamper-proof record of device interactions.
  7. Intrusion Detection Systems (IDS): By deploying IDS sensors, network traffic is observed for unusual activity, and administrators are notified of possible security breaches. IDS systems assist in quickly identifying and mitigating security events and offer real-time threat detection.

eInfochips, with its extensive experience in creating, building, and managing secure connected products across devices, faced a challenge to develop secure, market-ready solutions to strengthen IP camera security. This involves covering firmware, data encryption, and physical security. To overcome the challenge, eInfochips integrated threat modeling, secure product design, software analysis, penetration testing, and SD aspects into a comprehensive security requirement management system.
