What is Internet of Things (IoT)?
The Internet of Things, or IoT, is defined as the billions of physical devices all around the world that are now connected to the internet, all fetching and sharing data. Thanks to the arrival of super-cheap computer chips and the pervasiveness of wireless networks, it's possible to transform anything, from something as small as a pill to something as big as an airplane, into a part of the IoT. Linking up all these different objects and adding sensors to them integrates a level of digital intelligence to devices that would be otherwise dumb, enabling them to communicate real-time data without involving a human being. The Internet of Things is making the fabric of the world around us smarter and more responsive, combining the digital and physical universes.
In a nutshell, IoT involves integrating internet connectivity to a system of interrelated computing devices, mechanical and digital machines, objects, animals and/or people. Each "thing" is offered a unique identifier and the ability to automatically shift data over a network. Enabling devices to connect to the internet opens them up to a number of serious vulnerabilities if they are not properly protected.
IoT Need Security:
8 Types of IoT Security Threats
A botnet is a network that integrates several systems together to remotely take control over a victim’s system and distribute malware. Cybercriminals control botnets with the help of Command-and-Control-Servers to steal confidential and important data, steal online-banking data, and perform cyber attacks such as DDoS and phishing. Cybercriminals can use botnets to attack IoT devices that are linked to various other devices such as laptops, desktops, and smartphones.
Denial of service:
A denial-of-service (DoS) attack persistently tries to execute a capacity overload in the target system by sending multiple requests. Unlike phishing and brute-force attacks, attackers who implement denial-of-service don’t focus on stealing critical data. However, DoS can be utilized to slow down or paralyze a service to hurt the reputation of a business. For example, an airline that is attacked with denial-of-service will be unable to process requests for booking a new ticket, checking flight status, and canceling a ticket. In such cases, customers may switch to other airlines for air travel. Similarly, IoT security threats such as denial-of-service attacks can completely hamper the reputation of businesses and affect their revenue generation plans.
In a Man-in-the-Middle (MiTM) attack, a hacker infiltrates the communication channel between two individual systems in an attempt to intercept messages among them. Attackers gain control over their communication and send illegitimate messages to participating systems. Such attacks can be utilized to hack IoT devices such as smart refrigerators and autonomous vehicles.
Identity and Data Theft:
Multiple data breaches surfaced in 2018 for compromising the data of millions of people. Confidential information such as personal details, credit and debit card credentials, and email addresses were stolen in these data breaches. Hackers can now attack IoT devices such as smart watches, smart meters, and smart home devices to gain additional data about various users and organizations. By fetching such data, attackers can perform more sophisticated and detailed identity theft.
Hackers use social engineering to control and manipulate people into giving up their sensitive information such as passwords and bank details. Alternatively, cybercriminals may utilize social engineering to access a system for secretly installing malicious software. Most of the time, social engineering attacks are performed using phishing emails, where an attacker has to generate convincing emails to manipulate people. However, social engineering attacks can be simpler to perform in case of IoT devices.
Advanced persistent threats:
Advanced persistent threats (APTs) are major security concern for several organizations. An advanced persistent threat is a focused cyber attack, where an intruder gains illegal access to a network and stays undetected for a prolonged period of time. Attackers focus on monitoring network activity and steal crucial data using advanced persistent threats. Such cyber attacks are difficult to prevent, detect, or mitigate.
Ransomware attacks have become one of the most infamous cyber threats. In this attack, a hacker uses malware to encrypt data that may be needed for business operations. An attacker will decrypt critical data only after receiving a ransom.
Documents rolled out by WikiLeaks have exhibited that intelligence agencies know about the existence of zero-day exploits in IoT devices, smartphones, and laptops. These documents infer that security agencies were planning to record public conversations secretly. These zero-day exploits can also be utilized by cybercriminals to record conversations of IoT users. For example, a hacker can attack a smart camera in an organization and record video footage of everyday business activities. With this approach, cybercriminals can secretly fetch confidential business information. Such IoT security threats will also result in major privacy violations.
Challenges Associated with IoT Security
Since the idea of networking appliances and other objects is a relatively new concept there are several challenges that prevent the securing of IoT devices and establishing end-to-end security in an IoT environment. During a product's design phase security is always given the least amount of priority. Additionally, because IoT is a nascent market, many product designers and manufacturers are more eager in getting their products to market quickly, rather than taking the needed steps to build security in from the beginning.
A major issue associated with IoT security is the utilization of hardcoded or default passwords, which can result in security breaches. Even if passwords are changed, most of the time they are not that strong to prevent the infiltration.
Another common concern facing IoT devices is that most of the time they are resource-constrained and do not have the computational resources essential to implement strong security. As such, many devices do not or cannot provide advanced security features. For instance, sensors that monitor humidity or temperature cannot handle advanced encryption or other security measures.
Plus, as many IoT devices are "set it and forget it" -- placed in the field or on a machine and left untouched until end of life -- they hardly ever get any security updates or patches. From a manufacturer's perspective, building security in from the start can be costly, slow down development and cause the device not to function as it should.
Connecting legacy assets not inherently engineered for IoT connectivity is another security challenge. Swapping legacy infrastructure with connected technology is considered cost-prohibitive; which will result in many assets being retrofitted with smart sensors. However, as legacy assets that likely have not been updated or ever had security against modern threats, the attack surface is expanded.
IoT security is also infected by a deficiency of industry-accepted standards. While several IoT security frameworks exist, there is no ideal framework agreed-upon. Big companies and industry organizations may have their personalized specific standards, while certain segments, such as industrial IoT, have proprietary, incompatible standards from industry leaders. The variety of these standards makes it difficult to not only secure systems, but also ensure interoperability between them.
Experts Recommend following ways to overcome these challenges:
When releasing data systems in any environment, security teams are traditionally provided with three options: fast, secure, and cheap. Unfortunately, reality often forces organizations to choose only two, leaving security out of the equation while cost and convenience remain the bane of data protection efforts for years to come. Therefore experts recommend to get rid of “connect first, secure later” attitude.
As physical device life cycles inevitably eclipse the manufacturer's security maintenance life cycles, organizations must set up their own comprehensive strategies for secure IoT deployment. Sharing responsibility for safety is crucial
Deficiency of cohesive and comprehensive industry legislation and standards, organizations can develop and enforce their personalized practices for IoT security.
The inclusion of 5G technologies will truly revolutionize the IoT market by freeing its potential through greater bandwidth, lower latency, increased capacity, reduced costs, and a slew of other benefits. While this is projected to increase device management capabilities from thousands of devices per square mile to millions, poor security practices are estimated to boost the threat landscape exponentially.
