The concept of the Internet of Things (IoT) aims at connecting physical objects to the internet and allows them to provide different services to communicate among various objects. IoT aims to connect each device to provide a universal connectivity. IoT has gained significant attention in the past few years. It includes multiple domains and applications such as smart home, smart healthcare, transportation, etc. The highly dynamic nature of the IoT environment brings new challenges and diverse service requirements offered to clients.<\/p>\n

According to Statista, the IoT devices worldwide are forecast to almost double from 15.1 billion in 2020 to more than 29 billion IoT devices in 2030. <\/em><\/p>\n

IoT is an era of \u201cSmart\u201d, connected products that communicate and transfer tremendous amounts of data and upload it to the cloud. Amid the demand for enhanced services and rapid expansion, accessing, creating, and sharing data globally across devices becomes imperative for greater control in our interconnected world. To ensure the integrity of this data-driven ecosystem, implementing IoT Security Testing is vital, fortifying systems against vulnerabilities and safeguarding the seamless flow of information.<\/p>\n

As the indispensability of these devices grows, so does the imperative to fortify them against evolving threats. With an increasing influx of potentially vulnerable devices entering the market, the urgency to conduct IoT Penetration Testing becomes paramount. Failure to implement proper security measures poses a heightened risk to our data and systems in an environment rife with diverse and sophisticated vulnerabilities.<\/p>\n

IoT is not just software but an entire hardware, software, web, and mobile interface system. This ecosystem is not very mature, and there are still major concerns around IoT adoption, primarily due to security threats. Security requirements in the IoT environment are not different from any other systems. Mobiles and laptops have dozens of software security solutions to protect them from attacks, but similar security solutions are rarely present to protect the rest of the Internet of Things, due to which security breaches are bound to happen.<\/p>\n

The struggle is most of the customers pay for products or services that have an explicit value and reason to purchase; complimentary features like security and privacy are not on the top priority list of their wants, and as a result, businesses don\u2019t put much effort into these aspects of their product. Customers don\u2019t perceive any value in carrying out the extra burden of cost on security features in lieu of primary functionality.<\/p>\n

Vulnerabilities in IoT<\/h2>\n

Vulnerabilities have already been identified in industries like automotive and healthcare, with specific instances where data manipulation or theft can occur. Examples include attacks on home automation systems and taking control of heating systems, air conditioning, lighting, and physical security systems.<\/p>\n

Most hackers can access public and private webcams worldwide by hacking into remote web cameras\u00a0using advanced tools. Malicious hackers can also gain access to medical equipment to speed patients\u2019 heart rates up or down or alter the amount of antibiotics provided to the patients by modifying the drug infusion pumps.<\/p>\n

Security experts Chris Valasek and Charlie Miller grabbed headlines with their research on the vulnerability of connected cars when they hacked into a Toyota Prius and a Ford Escape using a laptop plugged into the vehicle\u2019s diagnostic port.<\/p>\n

Once a vulnerability is discovered, all the connected devices can be hijacked and potentially open their entire network to view and attack. A good example is Botnets like Mirai, Reaper, IoTroop etc.<\/p>\n

The escalating menace of botnets poses a significant threat to modern security systems, as cybercriminals increasingly favor their versatile capability to infiltrate virtually any internet-connected device. Botnets can ensnare many devices, from PCs and laptops to mobile phones, smartwatches, and even smart kitchen appliances. These malicious networks, crafted to infect millions of devices concurrently, easily exploit unsecured systems. Implementing IoT Penetration Testing becomes crucial in fortifying defenses against autonomous bots that exploit vulnerabilities across interconnected devices through the internet.<\/p>\n

Hence, with the growing challenges of IoT devices, organizations should view security as a critical business consideration and work to improve their security attitude at every possible level. By incrementally improving cyber security<\/a> testing in IoT, organizations can effectively curb their risk of falling victim to cyber disasters. In fact, an organization should understand the risk and security requirements and decide how much security they want and how much they want to spend to build a robust system.<\/p>\n

End-to-end testing of IoT device security testing will ensure higher consistency, integrity, and scalability and provide a rich experience.<\/p>\n

Addressing Security From Initial Design To Operational Level<\/h2>\n

Security must be addressed throughout the device lifecycle, from the initial design to the operational level:<\/p>\n

Secure Booting<\/h3>\n

When the power is supplied to a device, the integrity of the software on the device is verified through a digital signature along with the software authorization to run on that device and signed by the entity that authorized it.\u00a0<\/strong><\/p>\n

Secure Access Control<\/h3>\n

Device-based access control mechanisms are like network-based access control systems like Microsoft Active Directory. If someone hacks into a network using corporate credentials, the compromised information would be limited to the areas authorized by those credentials.<\/p>\n

The principle of least privilege dictates that only the minimal access required to perform a function should be authorized to minimize the effectiveness of any security breach.\u00a0<\/strong><\/p>\n

Device Authentication<\/h3>\n

It is necessary to authenticate a device when plugged into a network, before receiving or transmitting data.\u00a0<\/strong><\/p>\n

Firewalls<\/h3>\n

The device needs a firewall inspection capability to control traffic and filter specific data destined to terminate the device in a way that optimizes the limited computational resources available.\u00a0<\/strong><\/p>\n

Updates and Patches<\/h3>\n

Security patches and Software updates must be delivered considering the conservation of network bandwidth and the connectivity of embedded devices.<\/p>\n

For the seamless operation of IoT devices, it is critical to have robust Security at both the device and network levels. This does not require a revolutionary approach but rather a progression of measures that have proven successful in IT networks adapted to the challenges of IoT and to the constraints of connected devices.<\/p>\n

To optimize IT security controls in today\u2019s interconnected world and deliver complex applications driving IoT, security testing is the only discipline that helps organizations identify where they are vulnerable and take corrective measures to prevent and rectify the gaps.<\/p>\n

Common Approaches of Security Testing<\/h2>\n

Static Application Security Testing (SAST)<\/h3>\n

SAST, or White-Box Testing, is used to analyze the source code of applications to check for any security vulnerabilities. SAST solutions look at the application \u2018from the inside-out\u2019, without code compilation.\u00a0Gartner states that \u201cSAST should be a mandatory requirement for all organizations developing applications.\u201d With<\/em> 80% of attacks aimed at the application layer, according to Gartner, SAST is one of the top ways to ensure your application security is sound.<\/p>\n

When security testing isn\u2019t run throughout the SDLC, there\u2019s a higher risk of allowing vulnerabilities to get through to the released application, increasing the chance of allowing hackers through the application.<\/p>\n

Dynamic Application Security Testing (DAST)<\/h3>\n

DAST refers to testing the applications from the outside in. It involves checking the applications in their running state and trying to break them to discover security vulnerabilities.<\/p>\n

An approach that utilizes both SAST and DAST yields the most comprehensive testing.<\/p>\n
