The Internet of Things or IoT has swept the realm
of technology and become mainstream as far as automation is concerned. Its
popularity is attributable to features such as communication between machines, easy
usage, and the integration of various devices, enabling technologies, and
protocols.
When one talks about smart cities, smart
transport, smart healthcare, or smart homes, the role of IoT is paramount. According to Gartner, the number of connected
things courtesy IoT is projected to reach 20.8 billion by 2020. Since IoT is
about connected products that communicate with each other and share a huge
volume of data, it is vulnerable to security breaches. With greater
digitization and a rush towards delivering smart devices to add more comfort to
people’s lives, businesses may end up keeping their flanks uncovered. The
threats related to cybersecurity, besides threatening the smooth functioning of
the digital ecosystem, are putting a question mark on the implementation of the
IoT ecosystem.
The future is likely to be driven by smart systems
with IoT at their core. Since such systems will witness a huge exchange of
data, their security needs to be ensured. Also, as the smooth functioning of
such smart systems will hinge on the accuracy and integrity of data, enabling IoT
security at every step of the way should be the norm. If statistics are to be
believed then around 84% of companies adopting IoT have reported security
breaches of some kind (Source: Stoodnt.com.) The resident vulnerabilities in such
systems are exploited by cybercriminals to exhibit malicious behavior such as
committing credit card theft, phishing and spamming, distributed denial of
service attacks, and malware distribution, among others.
How to conduct IoT security testing effectively
The security implications of a vulnerable or
broken IoT system can be catastrophic for individuals, businesses, and
entities. The devices and the transfer of data within them should be monitored
by the implementing agency to check for a data breach. The best ways to conduct
IoT security is as follow:
Checking of endpoints: As more
devices or endpoints are added to expand the network, more vulnerabilities are
created. Since IoT systems are built using devices of different configurations,
computing and storage power, and running on different versions and types of
operating systems, every such device should be evaluated for safety. An
inventory of such devices should be made and tracked.
Authentication: Care should
be taken that the vendor-supplied default passwords for specific systems should
be dealt with at the beginning. If not, these can be exploited by hackers to
take control of the IoT ecosystem and wreak havoc. Moreover, every device in
the IoT system should be authenticated before being plugged into the network. This
should be made an integral part of the internet
of things testing.
Firewalls: The firewall
present in the network should be tested for its capability of filtering
specific data range and controlling traffic. Also, data aimed at terminating
the device to ensure its optimal performance should be tested.
Encryption: Since IoT
systems transmit data among themselves they should be encrypted for safety. During
testing IoT applications the
encryption approach and nitty-gritty should be thoroughly checked and
validated. If not, then while relaying the location of assets in the IoT
system, the information can be easily read by a hacker.
Compliance: Mere testing
of IoT devices is not complete unless compliance with standards like FCC and
ETSI/CE is carried out. These regulations and standards have been instituted to
validate the performance of the IoT devices based on certain parameters. So,
any IoT testing approach should take into account compliance
with such regulations.
Why IoT systems should undergo security testing?
The smart devices forming part of the IoT
system need to undergo IoT testing
(security) to:
Prevent data theft: The
unsecured endpoints within the system can leave a trail for hackers to strike
but for the IoT device testing
solutions. The vulnerabilities can be used to break into the controlling
mechanism of the system in order to launch more malicious forms of attacks.
Protect brand equity: When scores
of companies are competing with each other to get a pie of the IoT market, a
security breach or malware attack can put a brand in jeopardy. With IoT penetration testing, such attacks
can be pre-empted with the elimination of vulnerabilities and glitches.
Conclusion
The IoT ecosystem is projected to grow at a
humongous pace and scale. Technology companies having an integrated IoT security testing approach are likely to earn a huge
chunk of the pie. The approach when executed at regular intervals should be
able to help enterprises achieve growth across domains.
