Nowadays, the issue of security is very important in people’s lives, and they are doing their best to increase security as much as they can with the help of various tools.
All users who deal with the Internet have to try their best in order to be able to increase their knowledge in this field and read all the tips which are related to the field of security, it should be also noted that existence of gaps in security can cause serious damage to existing information.
In this article, we are going to address the issue of security challenges in Internet of Things , we hope that the content which is provided for you will be useful, and you can use it to get the best answer to your questions.
What Is IoT Security?
IoT security covers both the security of physical devices and the network security , which affects the processes, technologies, and measures required to protect IoT devices and networks, many devices are affected by this security, which means that all the devices which are connected to Internet will be affected by this security.
In the following, we are going to address a number of challenges in this field.
security challenges in Internet of Things:
- Weak password protection:
This is one of the challenges in this field which can pose many risks to IoT devices, hackers can easily access various devices through this way so that they can eventually take control of the device.
As you know, you should never use passwords that are easy to guess because if you do so, you will let attackers infiltrate your system easily , as a result, they can log in to your account and achieve their desired data.
There are several tools which are being used in this situation, including the Mirai malware , in which the system can infect IoT devices by using a table of 61 usernames and hard-coded default passwords.
Reports indicate that there are many devices that have been attacked by using this software to date, as a result, it is considered as an undeniable danger for security of various systems.
Large companies have not been spared the danger of this hacking method, among which we can mention Twitter.
One of your concerns may be about the ways to secure devices in loT so that hackers cannot take control of them, the steps that must be taken is that you have to choose complex or one-time passwords, you should also enable the option which locks your account when you enter the wrong password, and you have to select a specific date for the expiration of the password, as a result, you can increase the security of these devices by paying attention to the points that have been mentioned above which can help you a lot in this field.
It should be noted that one of the most important things that can make increase the level of security is two-factor or multi-factor authentication, which if you use, you can ensure that no one is able to have unauthorized access to devices which are connected to the Internet.
- Lack of secure data storage:
Another challenge facing this type of security is the lack of secure data storage, as you know, one of the ways that hackers can gain unauthorized access to the information they want is to attack information that is being transmitted between two servers.
One of these attacks is called Man-in-The-Middle attack , which you must have heard the name of it until now, and you may be familiar with it.
In order to protect your information from such attacks, you need to use a complex password for the information which you are transmitting so that hackers cannot easily achieve their malicious goals.
Many people may not pay attention to the fact that if they do not take the necessary steps, they will eventually regret it and have to pay a lot of money in the future in order to retrieve their information.
- No update:
This is another way that hackers can use in order to find the security bugs and gain access to the target device as soon as possible.
It is considered as a necessity for all users to pay attention to the updated versions (in German: Achten Sie auf die aktualisierten Versionen ) of the security programs which are provided for them so that they can ultimately increase the security of devices in IoT (in Spanish: aumentar la seguridad de los dispositivos en IoT ).
We can mention a piece of malware in this field which is called Satori, it is being used in order to let hackers enter various devices.
It should be noted that you should pay attention to some points while you are updating, among which we can mention backing up old data because as you know, it is possible that you lose your important data all at once while updating, so you need to pay attention to this point as well.
- Insecure interfaces:
This challenge and its solution is largely dependent on the manufacturers of IoT devices, and day by day, developers are paying more attention to these fields in order to keep their users satisfied and provide them with more security.
Some hackers use damaged devices in order to infiltrate IoT systems as well as devices so that they will eventually take control of the devices, which causes irreparable damage to the owners of the information and the owners of the devices.
- Not using specialized personnel:
Another challenge with these devices is that their owners do not use specialized personnel in order to get help from them and enhance the security of their systems .
There are a lot of experts who have done a lot of research in this area, and they have a lot of information so that getting help from them can be so helpful, for example, when you are planning to update various programs, if you do not have the necessary expertise in this field, you have to get help from experts so that there is no problem while doing this process.
In addition to the challenges which we mentioned so far in this article, there are other ones as well, which need to be mastered by different people who want to increase the security of their devices and finally be able to provide high level of security .
In general, there are many do’s and don'ts that need to be considered in this regard, any device that has the ability to be connected to the Internet will eventually be affected by these challenges.
It is necessary to pay attention to the fact that as almost every task is being done online and people prefer to do their daily tasks through this way, there is more and more information as well as devices that hackers can penetrate them in different ways and finally use the information which are obtained in order to achieve their sinister goals.
As you know, these days, due to the special situation, many companies try to give the opportunity of using their facilities online but while doing so, they may let hackers gain access to their systems, for instance, many company managers, try to check the employees through some cameras in order to have control over their work, this method can be so dangerous due to the fact that hackers can easily gain access to this system in order to gain essential information which may cause the company to lose its credibility, as a result, when a company loses its credibility, and people cannot trust them, there would be no customer who prefer to use their services.
In this article, we have reviewed a number of security challenges which are related to IoT related devices so that different users can increase the security of their systems by studying these cases and raising their awareness about them, as a result, they can prevent that profiteers from gaining access to their essential information due to the fact that hackers can inflict great damage on security of devices, so regaining the security can be so hard and time-consuming, it should be also noted that customers will lose their trust in system owners which can be considered as great harm to their success due to the fact that the number of customers will be decreased day by day.Click to audit your website SEO
