Top 7 Security Measures for IoT Systems

It is important to understand that the Internet of Things (IoT) is based on the concept of providing remote user access anywhere around the world to acquire data, operate computers, and other devices. The widespread IoT network includes computing devices along with unrelated machines that are solely responsible to transfer data excluding human-to-computer or human-to-human involvement.

The outbreak of technology and vitality smart devices in diverse sectors such as energy, finance, government, etc, makes it imperative to focus on their security standards. As per security firm, Kaspersky, close to one-third (28%) of companies managing IoT systems were threatened with attacks impacting their internet-connected devices during the year 2019. Furthermore, almost 61% of organizations are actively making use of IoT platforms; thereby, enhancing the overall scope for IoT security in the coming years.

Below are seven crucial steps for a business to uplift IoT security for preventing a data breach.

Swapping Default Passwords

The foremost step to enhance IoT security is through a sensible approach. It is recommended for businesses to enforce procedures that permit the changing of default passwords. This action should be implemented for each of their IoT devices present on the network. In addition, the updated passwords need to be changed on a timely basis. For added safety, the passwords can be simply stored in a password vault. This step can prevent unauthorized users from gaining access to valuable information.

Detach Corporate Network

Count it as an essential step to split the corporate network from unmanaged IoT devices. This can include security cameras, HVAC systems, temperature control devices, smart televisions, electronic signage, security NVRs and DVRs, media centers, network-connected lighting, and network-connected clocks. The businesses can make use of VLANs to separate and further track various IoT devices active on the network. This also allows analyzing important functions like facility operations, medical equipment, and security operations.

Limit Unnecessary Internet Admittance to IoT Devices

Many devices run on outdated operating systems. This can become a threat since any such embedded operating system can be purposely reached out to command and direct locations. In the past, there have been incidents when such systems have been compromised before they got transported from other nations. To completely wash out an IoT security threat is not possible but IoT devices can be prevented from communicating outside the organization. Such a preventive measure outstandingly reduces the dangers of a potential IoT security breach.

Control Vendor Access to IoT Devices

In order to improve IoT security, several businesses have limited the count of vendors gaining access to different IoT devices. As a smart move, you can limit access to those individuals already functioning under the careful supervision of skilled employees. In case remote access is highly necessary, keep a check that vendors make use of the same solutions similar to in-house personnel. This can include access via a corporate VPN solution. Moreover, enterprises should assign a staff member to supervise remote access solutions on a regularly. This individual should be well versed in certain aspects of software testing to manage the task with proficiency.

Incorporate Vulnerability Scanner

The use of vulnerability scanners is an effective method in detecting the different types of devices linked to a network. This can be viewed as a useful tool for businesses to improve their IoT security. Vulnerability scanner in collaboration with a regular scanning schedule is capable of spotting known vulnerabilities related to connected devices. You can easily access several affordable choices of vulnerability scanners available in the market. If not a vulnerability scanner, try accessing free scanning options such as NMAP.

Utilize Network Access Control (NAC)

An organization can successfully improve IoT security by implementing a NAC solution consisting of a proper switch and wireless assimilations. This setup can help detect most devices and recognize problematic connections within the network. A NAC solution, for example, ForeScout, Aruba ClearPass, or CISCO ISE, are efficient tools to secure your business network. If in case a NAC solution doesn’t fall within the budget, you can make use of a vulnerability scanner for fulfilling the purpose.

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.

What are 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.

How could your IoT devices be vulnerable?

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.

Tips to secure your IoT devices

1. Change Default Router Name

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.

2. Know your connected network and connected devices

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.

3. Change default usernames and passwords

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.

4. Manage strong, Unique passwords for your IoT devices and accounts

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.

5. Do not use Public WI-FI Networks

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.

6. Establish firewalls to discover the vulnerabilities

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.

7. Reconfigure your device settings

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.

8. Authenticate the IoT applications

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.

9. Update the device software up to date

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.

10. Track the smartphones and keep them safe

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.

Top 5 IoT Security Challenges to Expect in 2020

IoT has already become a well-known technology in the era of digital transformation. IoT can be seen as the next-gen interconnection paradigm which will allow connectivity amongst folk’s machines and devices without human intervention. It is the high-technology behind smartest cities, self-driving cars, and smart homes. A simple IoT app can make a huge difference in potential value by collecting insights and data for companies about not only who they are speaking to, but when, where, how much, and in which way.

Industry analysts have started calling IoT-the Industrial Revolution 4.0. Current efforts are focussed to interconnect IoT infrastructure and cloud-based technology which supplements the potentials of the Internet of Things While IoT machines and devices automate things, bring effectual communication between devices, save cost and time, there is one thing still concerning the consumers i.e. IoT security. There have been so many events that have made the IoT gadgets challenging to trust.

Highlights for IoT Statistics

The Internet of Things is now considered as the next big thing. IoT statistics reports are demonstrating how technical innovations will have a critical role in banking and finance, marketing, economy, healthcare, as well as government organizations.

  • The global IoT market hit $100 billion in revenue for the first time in the year 2017, and experts suggest that this number will jump to about USD 1.6 trillion by 2025.

  • As suggested by Forbes, its IoT market may get double and will hit around USD$520 billion by the end of 2021. The fame of IoT-connected gadgets has result to an increase in the development as well as the demand for IoT apps. However, IoT app development still has its set of challenges and security issues that cannot be ignored.
  • Cisco IoT statistics also proposed a more modest number of approximately thirty billion IoT devices by the year 2020.
  • FinancesOnlne IoT market trends hint that B2B IoT devices will grow to 5.4 billion in 2020 from 2.5 billion in 2017.
  • McKinsey’s IoT growth stats say, there are around 127 new IoT things connecting to the net each second.
  • According to Gartner’s IoT penetration stats, there will be almost 25 billion IoT devices in the whole world. On the flip side, Intel’s report forecasts 200 billion or more IoT devices connected to the Internet.

Lax Security Exposes Smart-Irrigation Systems to Attack Across the Globe

More than 100 smart-irrigation systems deployed across the globe were installed without changing the factory’s default, passwordless setting, leaving them vulnerable to malicious attacks, according to recent findings from Israeli security research firm Security Joes.

The researchers immediately alerted CERT Israel, the affected companies and the irrigation system vendor, Mottech Water Management, which did not immediately respond to a request for comment from Threatpost.

Mottech’s system allows for real-time control and monitoring of irrigation for both agricultural and turf/landscaping installations, via desktop and mobile phone. Sensor networks allow for the flexible and real-time allocation of water and fertilizer to different valves in the system. Access to the network could result in an attacker being able to flood fields or over-deliver fertilizer, for instance.

Security Joes regularly scans for Israeli open devices on the internet to check for vulnerabilities, the firm’s co-founder Ido Naor told Threatpost. Recently, its researchers discovered that 55 irrigation systems within Israel were visible on the open internet without password protections. After expanding their search, they found 50 others scattered around the world in countries including France, South Korea, Switzerland and the U.S.

“We’re talking about full-fledged irrigation systems, they could be entire cities,” Naor said. “We don’t look closely at what’s behind the address, because we don’t want to cause any trouble.”

Naor said that at last check, only about 20 percent of the identified vulnerable irrigation devices have had mitigation efforts taken to protect them so far.

Israel’s Water Systems Under Attack

There’s good reason for alarm about water systems not being secured, particularly in Israel. Just last April, a cyberattack on Israeli water systems, reportedly launched by Iran, attempted to increase the mix of chlorine in the water to poison the civilian population and ultimately interrupt the population’s water supply, The Times of Israel reported.

Yigal Unna, the head of the country’s National Cyber Directorate addressed the CybertechLive Asia conference in late May with the ominous warning that the direct cyberattack on people represented a new chapter in cyberwarfare, according to The Times of Israel.

“Cyber-winter is coming and coming even faster than I suspected,” he told the conference, according to the report. “We are just seeing the beginning.”

Unna was correct. Just weeks later in July, the Israeli Water Authority said that it was able to stop an attack on agricultural water pumps in Galilee, and another on water-supply infrastructure in the “center of the country,” reports.

The irrigation systems which were discovered without password protection aren’t related to the previous attacks, Naor said.

Locking Down Utilities Beyond Israel

These types of vulnerabilities certainly aren’t limited to Israel.

Last month, six critical flaws in CodeMeter, software used to power industrial systems in the U.S., including water and electric utilities, were discovered which could be exploited to launch attacks or even allow third-party takeovers of systems.

Over the summer, researchers found that VPNs used for remote access to operational technology (OT) networks in industrial environments left field devices open to attacks, which could cause shutdowns or even physical damage.

Governments are making attempts to keep up with the proliferation of internet-of-things (IoT) devices throughout critical-infrastructure systems. In the U.S., the House of Representatives passed legislation in September establishing minimum requirements for IoT devices within the federal government.

“Most experts expect tens of billions of devices operating on our networks within the next several years as the [IoT] landscape continues to expand,” the legislation’s so-sponsor Senator Cory Gardner (R-Co.) said in a press release. “We need to make sure these devices are secure from malicious cyberattacks as they continue to transform our society and add countless new entry points into our networks, particularly when they are integrated into the federal government’s networks.”

OWASP Top 10 API Security - DZone Security

I am sure that almost all of you would be aware about OWASP. But, just for the context let me just brief about the same.

OWASP is an international non-profit organization that is dedicated to web application security. It is a completely opensource and community driven effort to share articles, methodologies, documentation, tools, and technologies in the field of web application security.

When we talk about API, we are almost every time talking about REST and OWASP has a dedicated project to API security. As this series of articles are focused towards the API security, we shall not be going in details of web application security. You can use the provided links to find more about these. Let us spend some time on the background, before we dive deep in to API security project.

Background

OWASP’s most widely acknowledged project is OWASP top 10. This is the list of security risks compiled by the security experts from across the world. This report is continuously updated, outlining the concerns of web application security, and specially focuses on the Top 10 of the most critical risks. According to OWASP, this report is an “The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications.” They recommend that all companies incorporate the report into their processes in order to minimize and/or mitigate security risks. The latest version was published in 2017 and below is the list.

  1. Injection
  2. Broken Authentication
  3. Sensitive Data Exposure
  4. XML Eternal Entities (or XXE)
  5. Broken Access Control
  6. Security Misconfiguration
  7. Cross-Site Scripting (or XSS)
  8. Insecure Deserialization
  9. Using Components With known vulenerabilities
  10. Insufficient Logging And Monitoring

How API Security Is Different from Web Application Security

Although API’s have many similarities with web applications, but both are fundamentally different in nature.

In web applications, all the processing is done on the servers and the resulting web page is sent back to web-browser for rendering. Because of this nature, they have limited entry point and attack surface which are resulting web pages. This can easily be protected by putting up and web-application firewall (WAF) in front of the application server.WAF

In most of the modern application UI itself uses API’s to send and receive data from backend servers and provide the functionality of the application. It is the responsibility of the clients to do the rendering and convert the responses to a web page.

API GET and raw data

Also, with the rise of microservices architecture individual components become APIs, and it becomes a different world altogether, where UI clients could interact with hundreds of services via API calls. This significantly increases the attack surface. Now all those API’s become the entry point and attack surface.

These entry points can’t be guarded using the WAF solutions as they cannot differentiate between the legitimate and malicious API calls.

Why A Separate Project on API security?

Since its first release in 2003 OWASP top 10 projects has been the most useful resource in terms of web application security risks and to suggest the ways to mitigate these issues.

These days almost all the application development like banking, retail, transportation, smart devices, are done with the APIs.

APIs are critical to modern mobile and SaaS application. By nature, the API’s expose business logic and data, often these data are sensitive in nature, for example Personally Identifiable Information (PII). Because of this API’s are increasingly being targeted by attackers.

As API’s are changing how we design and develop our application, this is also changing the way we think about our security. A new approach in needed in terms of security risks. To cater to this need, OWASP decided to come up with another version of Top 10 dedicated to API security which is named “OWASP API Security Project”. The first report was released on 26 December 2019.

Below is the OWASP Top 10 API security risks and their brief description as provided by the official report.

API1:2019 Broken Object Level Authorization

APIs tend to expose endpoints that handle object identifiers, creating a wide attack surface Level Access Control issue. Object level authorization checks should be considered in every function that accesses a data source using an input from the user.

API2:2019 Broken User Authentication

Authentication mechanisms are often implemented incorrectly, allowing attackers to compromise authentication tokens or to exploit implementation flaws to assume other user’s identities temporarily or permanently. Compromising system’s ability to identify the client/user, compromises API security overall.
