10 Giant Security Challenges for the Internet of Things

By the end of 2020, the market size of IoT is expected to grow till the peak. This upliftment in the fame of IoT-liked devices leads to the rise in IoT app development that comes along with its good spread of security challenges and concerns. 

As the manufacturers are continuously competing on who would handover the modern device to the customers first? A few of them are acknowledging the security issues connected with the data management and access and also with the IoT devices themselves. 

Here, the question arises: what’s the biggest security challenges presently troubling the realm of IoT-linked devices?

Today, we are going to start with the same discussion on 10 largest challenges as below:

1. Default Password Issue and Brute-Forcing

Default Password Issue and Brute-Forcing

Employed in some of the most disruptive and largest DDoS attacks, the Mirai botnet is perhaps one of the best instances of the problems that come along with the shipping devices with default passwords and not advising the clients to update them as soon as they get them. There exist some of the government reports that tell the manufacturers against selling the IoT devices that come in-hand with the default (hackable, read) credentials like utilizing “admin” as passwords and/or username. 

It’s accepted that now, these are nothing more than that of the guidelines, and there exist no legal effects to incentivize the manufacturers to drop this risky practice. 

Login details and weak credentials expose mostly all IoT devices exposed to the brute-forcing and hacking in particular. 

Mirai malware was in a win-win position because it held the caliber of identifying the vulnerable IoT devices and employed the default login details and infect them. 

That’s why any company making use of the default credentials on their devices is just placing both their assets and business and also the customers and their confidential details at risk of being sensitive to a brute-force attack. 

2. Insufficient Updating and Testing

Insufficient Updating and Testing

Right now, worldwide there exist over 23 billion IoT-linked devices. By 2020, this figure is going to rise. This huge wave of new gadgets arrives only with a cost. 

Actually, among various problems of device building tech companies, one that’s the most significant is their careless nature which they reveal when it’s the turn of handling the device-relevant security risks. 

IoT products and most of these devices don’t experience sufficient updates, while some just don’t witness any updates at all. This directly points to the devices that were thought of being secured once when first reached the customers and later eventually becomes insecure and prone to hackers and distinct security issues. 

The same problem also happened with the early computer systems, which was slightly got resolved with the automatic updates. 

However, IoT manufacturers are more curious to build and deliver their devices as soon as possible, without giving more time and thought to the security. 

Unluckily, most of the manufacturers provide the firmware updates only for less time, for the sake of stopping the minute they begin with the performance on the upcoming widely known gadget. Even worse, they employ unsupported legacy Linux kernels. This results in exposing their trusted clients to potential attacks that drive towards outdated software and hardware. 

To safeguard their consumers from akin attacks, every device demands proper testing before the launch and companies are required to regularly update them.

If they become failed to conduct this, it becomes bad for both consumers and companies, as it charges only a sole large-scale violation in the consumer data to ruin the company completely. 

3. IoT Botnets targeting Cryptocurrency

IoT Botnets targeting Cryptocurrency

The on-fire mining competition, linked with the current growth of cryptocurrency valuations is looking too captivating for the hackers who try to cash-in on the crypto craze. 

While for some, the blockchain is resistant to hacking, the attacks are growing day-by-day while blockchain sectors are rising noticeably. The main risk is not blockchain, but preferably the blockchain app development going on it. 

To take out the usernames, private keys, and passwords, social engineering is conducted already and also we will notice its utilization most often in the coming days to hack the blockchain-based apps. 

Monero, an open-source cryptocurrency, is one among the various digital currencies being used today mined with IoT devices. Some of the video cameras and IP have been repurposed by some of the hackers to mine crypto. 

IoT botnet miners, blockchain breaches, and data manipulation of the data integrity act like a big risk for drowning the wide crypto-market and disturbing the structure and previously volatile value of cryptocurrencies. 

IoT platforms, structure, and apps rely on the need for blockchain technology to become constantly monitored and regulated and updated if it is meant to save any future exploits of cryptocurrency. 

4. Ransomware and IoT Malware

Ransomware and IoT Malware

In the coming years, as the IoT-linked devices are going to rise continuously, so will the ransomware and malware employed to exploit them. 

While the common ransomware depends on encryption to lock-out users entirely of distinct platforms and devices, there’s a continuous hybridization of both the ransomware and malware strains that targets to join the distinct sorts of attacks. 

The ransomware attacks could target limiting or/and disabling the functionality of devices potentially and stealing the user data simultaneously. 

The ever-growing IoT devices will result in unpredictability concerning upcoming attack permutations. 

5. Small IoT attacks that Avoid Detection

Small IoT attacks that Avoid Detection

Past two years, the biggest IoT-based botnet was the Mirai botnet. It was the Reaper in 2017, an importantly most risky botnet as compared to the widely-known Mirai. 

As significant as the large-scale attacks, in 2018 we should be scared of the small-scale attacks that avoid detection. In a couple of years, we just assure to witness more and more small breachers getting freed from the security net. 

Despite employing the huge guns, the hackers will mostly be employing a precise attack, small enough to allow the leakage of information instead of just clutching millions of records at one time.

6. Privacy and Data Security Concerns (web, mobile, cloud)

Data security and privacy are constantly being the only biggest issue as per the interconnected world today. 

Data is without any delay being checked, shared, stored, and also being processed by big companies employing a wide range of IoT devices like speakers, smart TVs, and lighting systems, HVAC systems, linked printers, and smart thermostats. 

Typically, this entire user-data is transmitted between or even sold to many companies, not following our rights for data security and privacy, and further leads to public distrust. 

Privacy and Data Security Concerns

We are required to set privacy rules and dedicated compliance that anonymizes and redact sensitive data before disassociating and storing IoT data payloads from the details that can be employed to identify us personally. 

No longer required and cached data then should be disposed-off securely. The stored data will then be the biggest challenge in assent with several regulatory and legal structures. 

The same method should be used with web, mobile, and cloud apps, and services employed to manage access, and process linked data with IoT devices. Secure development of the web-based and mobile app IoT apps can be a little tough for small companies with limited manpower and budgets. 

As mentioned already, most of the manufacturers point towards focusing entirely on availing the app and device in the market rapidly to magnetize even more funding and begin the growth of the user base. 

Unless you wish like risking a major violation of security and IoT Botnets focusing on Cryptocurrency. 

The on-fire mining competition, linked with the current growth of cryptocurrency valuations is looking too captivating for the hackers who try to cash-in on the crypto craze. 

While for some, the blockchain is resistant to hacking, the attacks are growing day-by-day while blockchain sectors are rising noticeably. The main risk is not blockchain, but preferably the blockchain app development going on it. 

To take out the usernames, private keys, and passwords, social engineering is conducted already and also we will notice its utilization most often in the coming days to hack the blockchain-based apps. 

Monero, an open-source cryptocurrency, is one among the various digital currencies being used today mined with IoT devices. Some of the video cameras and IP have been repurposed by some of the hackers to mine crypto. 

IoT botnet miners, blockchain breaches, and data manipulation of the data integrity act like a big risk for drowning the wide crypto-market and disturbing the structure and previously volatile value of cryptocurrencies. 

IoT platforms, structure, and apps relying on the need for blockchain technology to become constantly monitored and regulated and updated if it is meant to save any future exploits of cryptocurrency. 

7. AI and Automation

AI and Automation

As IoT is constantly invading our routine lives, eventually, the enterprise will have to deal with hundreds of thousands or even millions of IoT devices. This much of user data would be hard to manage from the perspectives of networking and data collection. 

AI automation and tools are in use already to filter huge amounts of data and one day could assist network security officers and IoT administrators to apply data-specific rules and monitor anomalous data and the patterns of traffic.

Furthermore, utilizing autonomous systems to build autonomous decisions that infect millions of the functions all across large infrastructures like power, healthcare, and transformation that might be risky, primarily when acknowledging that it only needs a misbehaving algorithm or a single error in the code to destroy the complete infrastructure. 

These were just the most critical IoT security challenges that we require to review while building an app depending on IoT in the upcoming years. 

As we can notice, most of them just circulate all around the two aspects, holding IoT security from the attacking and making the user data secure from theft. 

These two challenges can be settled with strict regulatory and legal frameworks targeted at the manufacturers, with huge fines and the working constriction employed for the one who doesn’t prefer following the said frameworks. 

8. Home Invasions

Probably, one of the most dangerous threats that IoT can act is of the home invasion. Today, IoT devices are utilized increasingly at offices and homes which has to lead to the boost of the home automation. 

The security is the biggest matter of concern when it comes to the IoT devices as it can leak the consumers’ IP address that can locate a residential address. The hackers can sell this important information to underground sites that are havens for criminal outfits. 

Furthermore, if one is employing IoT devices in the security systems, then compromise can be a probable cause there which can drive your house towards a big potential threat. 

9. Remote Vehicle Threat

Except for the home invasion, one more threat that IoT posses are car hijack. Soon, smart cars would become a reality with the assistance of IoT devices connected. Though, because of its IoT link, it also clutches a huge risk of a car hijack. 

A talented hacker may hijack by winning the access of your smart car by the remote access. This will be a dangerous situation as one can earn control over your car and this can expose you to the lethal crimes. 

10. Untrustworthy Conversation

There exist various IoT devices that hold the power of sending messages to the network with no encryption. This is one of the huge IoT security challenges that stays out there. It’s high time now, that insists the companies assure the encryption of the top-level among their devices and cloud services. 

To be away from such a threat, the best way out is to employ transport encryption along with the standards such as TLS. Another option is to utilize distinct networks that keep distinct devices separated. 

One can also employ the private conversation which assures that the data passed on is confidential and secure.
