Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.
The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.
Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.
When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.
When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.
Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.
The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.
Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.
If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.
When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.
Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.
Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.
Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.
There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.
Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.
Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.
Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.
When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.
However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.
If you have any, feel free to share them in the comments! I’d love to know them.

At Arduino, we are hard at work to keep improving the security of our hardware and software products, and we would like to run you through how our IoT Cloud service works.
The Arduino IoT Cloud‘s security is based on three key elements:
In the past, it has been challenging to create a complete SSL/TLS library implementation on embedded (constrained) devices with very limited resources.
An Arduino MKR WiFi 1010, for instance, only has 32KB of RAM while the standard SSL/TLS protocol implementations were designed for more powerful devices with ~256MB of RAM.
As of today, a lot of embedded devices still do not properly implement the full SSL/TLS stack and fail to implement good security because they misuse or strip functionalities from the library, e.g. we found out that a lot of off-brand boards use code that does not actually validate the server’s certificate, making them an easy target for server impersonation and man-in-the-middle attacks.
Security is paramount to us, and we do not want to make compromises in this regard when it comes to our offering in both hardware and software. We are therefore always looking at “safe by default” settings and implementations.
Particularly in the IoT era, operating without specific security measures in place puts customers and their data at risk.
This is why we wanted to make sure the security standards adopted nowadays in high-performance settings are ported to microcontrollers (MCUs) and embedded devices.
Back in 2017, while looking at different SSL/TLS libraries supporting TLS 1.2 and modern cryptography (something that could work with very little RAM/ROM footprint, have no OS dependency, and be compatible with the embedded C world), we decided to give BearSSL a try.
BearSSL provides an implementation of the SSL/TLS protocol (RFC 5246) written in C and developed by Thomas Pornin.
Optimized for constrained devices, BearSSL aims at small code footprint and low RAM usage. As per its guiding rules, it tries to find a reasonable trade-off between several partly conflicting goals:

With an immense number of companies and entities climbing onto the digital bandwagon, cybersecurity considerations have come up as limelight. Besides, new technologies such as Big Data, IoT, and Artificial Intelligence/Machine Learning are gradually more making inroads into our everyday lives, the threats related to cybercrime are mounting as well. Additionally, the usage of mobile and web apps in transacting financial information has put the complete digital stuff exposed to cybersecurity breaches. The inherent risks and vulnerabilities found in such apps can be exploited by attackers or cybercriminals to draw off crucial information data counting money. Internationally, cyber-security breaches have caused a yearly loss of USD 20.38 million in 2019 (Source: Statista). Plus, cybercrime has led to a 0.80 percent loss of the entire world’s Gross domestic product, which sums up to approx. USD 2.1 trillion in the year 2019 alone (Source: Cybriant.com).

What is 2FA
Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account.
Employing a 2FA mechanism is a vast improvement in security over the Singe-Factor Authentication method of simply employing a username and password. Using this method, accounts that have 2FA enabled, require the user to enter a one-time passcode that is generated by an external application. The 2FA passcode (usually a six-digit number) is required to be input into the passcode field before access is granted. The 2FA input is usually required directly after the username and password are entered by the client.

Storing and managing corporate data by applying the cloud is becoming more and more popular. Companies grow, and it gets too expensive, and resources consuming to store their data on traditional servers. To prove it, look at the research conducted by Google in 2019 that includes insights for the cloud computing market for the next 10 years.
Around 80% of US respondents (about 1,100 businesses participated) revealed that they are thinking about cloud adoption by 2029. In 2019, only about 40% made a switch. 72% of businesses state that they’d like to automate security solutions by 2029, while now only 33% actually do it.
What do these numbers tell us? That companies seem to be suspicious about cloud security and prefer traditional on-premises data storage to the cloud environment. Why are they afraid to entrust cloud providers with their data? What to do to get rid of this fear? How to prove that the future of security is after the cloud?
In our article, we aim to answer these questions and more, but first, you need to be able to identify the reasons why companies have cloud-related trust issues. The first step in eliminating a problem is identifying it, let’s do it together!
