The internet of things (IoT) is the huge network of tangible objects (i.e. objects) that share information with other devices and systems over the internet. Although it is a reference to real objects, IoT is commonly used as an umbrella term to describe a widely distributed network that is able to combine connectivity, sensors, and light applications that are integrated into devices and tools. They are used to share information with different devices, applications and systems that range from smart devices and power grids to connected vehicles and medical devices.
IDC defines an IoT solution as “a network of uniquely identifiable endpoints (or things) that communicate without human interaction using IP connectivity–whether locally or globally. IoT gives significance to the notion of connectivity everywhere for businesses government, consumers, and even governments by allowing for monitoring, management as well as analytics.”
In the wake of low-cost computing as well as the cloud technology, IoT has grown to become among the top widespread connected technologies, with billions of applications across the globe. IoT connects the physical and digital worlds by enabling seamless, continuous streaming of communications to everyday consumer products as well as complicated industrial systems.
What is IoT Security?
IoT security is a broad term that encompasses the tools, strategies and processes, as well as systems and techniques used to safeguard every aspect connected to the Internet of Things. In IoT security are the protection of physical components such as data, applications, as well as network connections to ensure the integrity, reliability and security and security of IoT ecosystems.
Security concerns are numerous, because of the numerous vulnerabilities that are frequently found on IoT systems. Secure IoT security encompasses all aspects of security, such as security measures like hardening the components and monitoring them, keeping the up-to-date with firmware security management for access, mitigation, and the remediation of weaknesses. IoT security is crucial because the systems are swarming and vulnerable, which makes them an extremely-targeted attack source. Secureing IoT devices from access that is not authorized will ensure that they do not be a gateway to other areas of the network or leak sensitive data.
IoT security vulnerabilities can be found all over the world, from cars and smart grids, to watches and smart home devices. For instance, researchers have discovered webcams that were easily compromised in order for accessing networks, as well as smartwatches with security flaws that let hackers track the wearer’s location as well as listen on conversations.
The importance of IoT Security
IoT is widely considered to be one of the most serious security flaws that affect almost everyone, consumers or organizations as well as governments. In spite of the ease and benefits derived from IoT devices, the dangers are the most severe. The significance of IoT security is not overstated as IoT devices offer cybercriminals a an extensive and easily accessible attack area.
IoT security is one of the most important security needed by vulnerable devices. The developers of IoT systems tend to focus on the capabilities of devices rather than security. This increases significance of IoT security and requires IT teams and users to be accountable for the implementation of security measures.
As mentioned above, IoT devices were not made specifically with security as a goal. This creates a variety of IoT security issues that could result in disasters. Contrary to other technologies IoT has no standard or guidelines that are in place to regulate IoT security. Additionally, the majority of people don’t know about the inherent dangers associated with IoT security systems. Also, they don’t have an notion of the extent of IoT security risks. Some of the IoT security concerns are:
Visibility issues
Many users use IoT equipment without expertise of IT departments. This means it is impossible to keep an accurate record of the devices that need to be monitored and protected.
Limited integration of security
Due to the diversity and the size of IoT devices, the process of integrating the devices into security systems varies from difficult to impractical.
Open-source code vulnerabilities
Firmware designed specifically for IoT devices typically includes open-source software that is vulnerable to security flaws and bugs.
Overwhelming data volume
The sheer volume of data created by IoT devices makes monitoring, managing and security a challenge.
Poor testing
Since the majority of IoT developers don’t pay attention to security, they are unable to carry out effective vulnerability testing to find vulnerabilities inside IoT systems.
Unpatched vulnerabilities
Many IoT devices are vulnerable to vulnerabilities that remain unpatched due to a variety of reasons, such as patches not being available , and issues installing patches and accessing them.
Vulnerable APIs
APIs are typically utilized as entry points into command-and-control facilities where attacks can be initiated, for example, SQL injection or distributed denial of services (DDoS) and man-in the-middle (MITM) and compromising networks
Weak passwords
IoT devices typically come with default passwords that a lot of users do not change, which gives cyber criminals an easy way to gain access. In other instances users make passwords that are weak that are easily identified.
Solutions to IoT Security Challenges
A comprehensive approach is needed for implementing and managing IoT security efficiently. It has to encompass a wide range of tools and techniques and also include other systems, like networks.
Three essential capabilities of an effective IoT security solution is the capability to:
Learn
Utilize security solutions which provide visibility into networks to know what the ecosystem covers and the risk profile for each type of IoT devices.
Secure
Monitor, inspect and implement IoT security policies in conjunction with different activities within the infrastructure
Segment
Similar to how networks are segmented in the same way, employ segmentation based on policies categories and risk profiling to classify IoT systems.
The specific features needed to secure IoT devices are the following:
API security
Broader and deeper IoT device inventory
Software updates continue to be continuous.
DNS filtering
Personnel for education and training, vendors, and other partners
Encryption of data in rest as well as in transit
Honeypot decoy programs
Multi-factor authentication
Security of the network
Analysis of network traffic monitoring
Management of passwords
Patch management
Security gateways
Unauthorized IoT device scans
Improve IoT Security to Realize Increased Profits
IoT devices are being increasingly utilized by both individuals and the corporate world. They’re not just staying around and are expanding exponentially in increasing numbers of forms. The result is a growing complexity, which hinders efforts to control IoT security for systems effectively.
IoT security issues can range from preventing malicious insiders, to defending against threats from nation-states. Due to the vulnerability inherent to IoT devices as well as the magnitude of their use, attacks continue to increase in size and reach.
Security of IoT devices is worthwhile, despite the IoT security concerns. The benefits that can be realized from IoT devices will only be improved with increased security to be competitive with other technologies. It can reduce risks and enhance the rewards.
IoT Security Best Practices
The first step to security for IoT is to know what’s connected. This requires the use of a device identification and discovery tool that can automate three essential IoT security features.
Continuously and automatically detects profiles and classesifies IoT devices connected to the network
Maintains a live inventory of devices
Provides relevant risk information for all these asset classes by continually checking across the attack channels.
Following these industry best methods to ensure IoT security and implementing the latest solutions, you will be able be aware of, manage and protect your entire inventory of assets, including IoT.
