Can IoT Ensures Network security?

SHARE:



The Technology of IoT security is concerned with safe connected devices and networks in the internet of things. It has aunique identifier and the ability to transfer data over a network automatically. Allowing devices to connect to the internet opens them up to a number of serious vulnerabilities if they are not properly protected. Introducing security measures is critical to ensuring the safety of networks with IoT devices which is connected to them.

IoT security challenges

A number of challenges prevent the securing of IoT devices and where app developers or app development companies were ensuring end-to-end security in an IoT environment. Additionally, because IoT is a nascent market, many product designers and manufacturers are more interested in getting their products to market quickly, rather than taking the necessary steps to build security in from the start.

However, as legacy assets that likely have not been updated or ever had security against modern threats, the attack surface is expanded.

In terms of updates, many systems only include support for a set timeframe. New security can lapse if more support is not added. When we are adding IoT device it in a network for years it is a challenge to control. Industries may have their own specific standards, while certain segments, such as industrial IoT, have proprietary, incompatible with other platform. The variety of these standards makes it difficult to not only secure systems, but also ensure interoperability between them.IT teams with the proper skill sets should be put in charge of IoT security.

What industries are most vulnerable to IoT security threats?

IoT security hacks can happen in any industry, from smart home to a manufacturing plant to a connected car. The severity of impact depends greatly on the individual system, the data collected and/or the information it contains.

An attack disabling the brakes of a connected car, for example, or on a connected health device, such as an insulin pump hacked to administer too much medication to a patient, can be life-threatening. Likewise, an attack on a refrigeration system housing medicine that is monitored by an IoT system can ruin the viability of a medicine if temperatures fluctuate. Similarly, an attack on critical infrastructure -- an oil well, energy grid or water supply -- can be disastrous.

Other attacks, however, cannot be underestimated. For example, an attack against smart door locks could potentially allow a burglar to enter a smart home. Or, in other scenarios such as the 2013 Target hack or other security breaches, an attacker could pass malware through a connected system -- an HVAC system in Target's case -- to scrape personally identifiable information, wreaking havoc for those affected.

Things to keep in mind on the security level;

Network security on IoT: IoT devices which are connected to the backend systems of the internet must be protected and secured is said to be network security on IoT. But it is a challenging task than the ordinary network security because it consists of wider range of communication protocols and its standards of device capabilities which can bring a significant trouble. It also consists of security issues like firewalls, antimalware, and intrusion prevention and detection systems.

Authentication on IoT: The user ability is to authenticate an IoT device which includes managing the multiple users of a single device such as, ranging from simple static password to more robust authentication mechanisms like two-factor authentication and biometrics must be provided. Without any human intervention or disturbance in the business networks where the authentication processes involve a human being entering a credential, many IoT authentication scenarios such as embedded sensors must be in a form of machine-to-machine based system.

Encryption: Encrypting data at rest and in transit between IoT edge devices and back-end systems using standard cryptographic algorithms, helping maintain data integrity and preventing data sniffing by hackers. The ability to have standard encryption processes and protocols must have a wider range of IoT devices and hardware profiles limits. Moreover, all IoT encryption must be accompanied by equivalent full encryption key lifecycle management processes, since poor key management will reduce overall security.

Security Analytics on IoT: IoT security analytics will increasingly be required to detect, aggregate, monitor and normalizing the data from IoT devices which provides an action to reporting and help us to alert on any specific activities which don’t obey rule of system policies. To get more predictive modelling and detection of the solution AI technique to the system must be add which gives us a predictive analysis and reduce the number of false positives.

API Security on IoT: Providing the ability to authenticate and authorize data movement between IoT devices, back-end systems, and applications using documented REST-based APIs. API security will be essential for protecting the integrity of data transiting between edge devices and back-end systems to ensure that only authorized devices, developers, and apps were communicating with the threats that detecting against potential and attacks against the APIs.

For example, Suggestions to make your smart home more secure

1. Selection on Router Name

Not to follow the easy or a name provided by the manufacturer, give an unusual name which is difficult to remember or understand.

2. Encryption method for Wi-Fi must be difficult

Follow a strong encryption method in router settings, like WPA2, when you started to access and set up the Wi-Fi network. This makes your network to be secure.

3. Set up a guest network

Maintain your Wi-Fi account to be private that no one can access like visitors, friends and relatives can log which means the other network doesn’t tie into your IoT devices.

4. Change default usernames and passwords

Cybercriminals probably already know the default passwords that come with many IoT products. That makes it easy for them to access your IoT devices and, potentially, the information on them. Are you considering a device that doesn’t allow you to change the default password? Then consider a different one.

5. Use strong, unique passwords for Wi-Fi networks and device accounts

Don’t have words which is easy to pronounce or a common words which may related to simple like password” or “123456.Instaed of that you must use a complex variables which must include with various symbols, numbers, and alphabet to make your secure level more harder to find out by other.

6. Check the setting for your devices

Each settings of your network must be handled properly with more secured way. Make sure to change or to know handle the default settings from the manufacture which is more strength to security level.

7. Keep your software up to date

Software update is nothing a but simple task like buying a new smartphone and later on it asks to update it, don’t put off installing it. It might be a patch for a security flaw. It is important, since you may connect to your smart home through mobile devices. Your IoT device makers also may send you updateor you might have to visit their websites to check for them.

8. Watch out for outages

Ensure that a hardware outage does not result in an unsecure state for the device. More IoT devices are going to be used for different purpose. Think to use the devices of IoT with more secure and more aware to not interference with the network issue.

Coda Words:

There are lot of IoT devices or IoT based app are trending which is going to be buzz in future. Hope the Information which I have gathered may give some awareness about IoT security.
