IOT Security Solutions to Protect Your Network and Devices
IOT, or Internet of Things is a network of physical objects containing technology like sensors, software and other technologies which can connect and exchange data with other devices over the internet.
IOT is one of the most important technologies of modern society. The ability to connect ‘things’ which we use on a daily basis like vehicles, kitchen appliances, house automation devices to the internet via embedded sensors and technologies is now the new normal.
IOT goes beyond our domestic lives. IoT is also used in industrial settings, Industrial IoT (IIoT). Through IIoT machines are able to communicate amongst themselves achieving wireless automation.
Anything connected to the internet can face an attack. Hackers can compromise IoT devices focusing on its vulnerability. Securing IoT devices and its infrastructure is of prime importance leading to IoT Security Solutions.
IOT Security Solutions focuses on protecting IoT devices and the networks they are connected to. Securing IoT devices is important because there is no built-in security in the devices, making it vulnerable.
IOT Security Challenges for Businesses
IOT because of its structure presents a wide range of cybersecurity vulnerabilities. The number of attacks have been increasing yearly. An IoT attack is an assault to an IoT device contaminating it with malware. IoT attacks are of many kinds, some of them are:
- Physical attacks: Attackers target the hardware of the IoT devices. This includes tampering with sensors, gaining illegal access to the devices causing a cyber attack.
- Encryption attacks: Unencrypted IoT devices can let attackers capture the data and encrypt it. Even after decrypting the encryption, attackers can still take control of the systems.
- Denial of Service (DoS) and Distributed Denial of Service (DDoS): Attackers can flood IoT systems with an overwhelming amount of traffic making them unusable. This also prevents legitimate users from accessing IoT devices.
- Botnets: Attackers hijack poorly secured and networked IoT devices, in turn making the devices into remotely controlled bots - Botnet. Botnets can be used to transfer private and sensitive data or can be used to disable devices.
- Man-in-the-Middle (MitM): This attack happens when attackers breach the communication amongst systems. The attackers secretly intercept and can even alter communication amongst systems. Through this attack attackers can convince the systems that they are receiving legitimate messages, while in reality the attackers are communicating to the systems. This can be used to steal sensitive information.
- Ransomware: Ransomware is the type of malware where attackers gain access to the files and encrypt the data. They later sell the decryption key for a ransom.
- Brute Force Password: Attackers submit many passwords hoping to guess the correct one. The passwords are usually guessed by a software providing multiple combinations. These passwords are then later used by multiple attackers to hack into the IoT devices. Once the access is gained, malware can be installed or data can be stolen.
Applications of IOT Security in Industries
The use of IoT is vast. From using them in houses to automating entire factories. There are numerous benefits in using IoT. Some of them are enhanced efficiency, reduced costs, decision making based on data generated by IoT devices and many more. IIoT has had a massive impact on Manufacturing and Healthcare industries.
All IoT devices need to be protected with a zero trust security approach. Through this every device has a trusted identity and is authenticated when entering the network.
In Manufacturing, IoT devices are many and exposed. The devices are everywhere from printers, cameras, HVAC systems etc. It is important to understand the attacks and the compliance gaps with real time risk assessments.
Manufacturing facilities contain machinery that can cause physical injury to employees when disrupted, which is what an IoT cyber attack can do. A successful physical cyber attack on operation technology with connected networks can disrupt a section of a manufacturing facility.
Cyber attacks on manufacturers can cause unplanned interruptions leading to significant costs to manufacturers and creating problems in the supply chain in turn reducing operational efficiency.
In Healthcare, IoT devices are specialized for medical purposes and are called Internet of Medical Things (IoMT) devices. The Healthcare industry is increasingly using IoT devices to conduct medical procedures and have more control over medical data and treatment. WIth increase in IoT devices the attack surface also increases.
Medical devices contain valuable and sensitive data that can be held to ransom, sold on the Dark Web or cause identity theft. Medical IoT devices such as pacemakers or health monitoring devices are life critical. Hackers are aware that cyber attacks on those devices can lead to death.
Infusion pumps make over half of the IoMT devices. Infusion pumps are used to manage and administer blood, saline and other medical fluids. A cyber attack on these devices can also cause potential harm to patients.
With similar cases across multiple industries businesses that invest in IoT devices should also invest in securing them, since IoT devices as such do not have any security.
Comprehensive IoT Security Solutions for Your Business
Key Features of Our IoT Security Solutions:
Reinfosec provides solutions for IoT devices and its infrastructure. Our solutions can make sure your IoT devices security is not weak and protect them from potential threats and vulnerabilities. Our solutions include:
Reinfosec has an effective device authentication system as a first wall of defense. Through this Brute Force password attack can be stopped.
Encryption of data is important for IoT device security. One of the most important features of IoT technology is the exchange of data, but without encryption when the data is hacked, attackers can encrypt the data.
IOT devices will be observed and the normal behavior will be recorded. Any anomalies after this can be easily recognizable with respect to policy violation, usual traffic or communication amongst systems that is not expected.
As the network expands, the new devices are added and need to be configured to device policies. Through policies we will be able to monitor device activity on a granular level.
Segmenting networks isolating IoT devices and its network with other networks reduces the risk and can grant IoT devices privileges based on its risk profile.
Once the controls are established our solution can consistently enforce policies across the network. Our Threat Intelligence is capable of soliciting information about threats globally.
Our Penetration Testing analyses the whole IoT ecosystem and how it impacts the whole security. Our testing includes IoT applications, embedded systems, communications amongst systems and cloud APIs.
Our testing solutions can examine the physical security of the device. This includes firmware extraction, component indication, testing bypassing for authentication, intercepting traffic and injecting commands
