3 Tips for Locating and Identifying IoT Devices On Your Enterprise Networks

Are you confident that your enterprise networks are secure? If so, can you be certain all approved IoT devices are accounted for and properly configured? It’s essential to identify every device connected to your network if only to ensure that it is not a malicious actor.

But identifying unauthorized network intruders is not the only reason for carefully inspecting your enterprise networks.

In this article, I’ll provide 3 tips for locating and identifying any Internet of Things (IoT) Devices on your enterprise networks. These tips will help you reduce vulnerability across your entire organization and ensure maximum data security.

Scan The Network

One of the best ways to locate and identify IoT devices on your enterprise networks is to scan the network for any active connections. This can be done using various tools such as nmap or a vulnerability scanning product. By scanning the network, you can see which devices are connecting to your network and get some idea of what they might be. Some tools, including nmap can guess the type of device it might be based on stack fingerprinting or services identified.

Scan For BlueTooth Devices

Many IoT devices use Bluetooth to connect to other devices or interact with users, and scanning for such devices can help you locate them. You can use a tool such as BLE Scanner to detect any active Bluetooth devices connected to your network. This will help you identify unapproved or unauthorized Bluetooth-enabled IoT devices on your networks.

Inventory MAC Addresses And ARP Data

Every IoT device connected to your network has a unique MAC address. By keeping an inventory of all the active MAC addresses, you can quickly identify any new or unauthorized devices connecting to your networks. Additionally, you should monitor ARP data for changes or anomalies. Detecting any suspicious activity could indicate that a malicious actor or unexpected device is attempting to connect to your network.

To look up the MAC address and identify the vendor of an IoT device, you can search using the MAC address on websites such as macvendors.com, which will show you who manufactured the device. Some network security and monitoring systems may also provide a way to look up MAC addresses, allowing you to identify any unauthorized devices on your enterprise networks quickly.

In conclusion, ensuring that all IoT devices connected to your enterprise networks are identified and adequately configured is essential. To do this, you should scan the network for active connections, scan for Bluetooth devices, and inventory MAC addresses and ARP data.

FAQ for Enterprise Authentication Inventory

Q: What is authentication inventory?

A: Authentication inventory is the process of identifying and documenting all of the systems and applications that require remote access within an organization, as well as the types of authentication used for each system and any additional security measures or policies related to remote access.

Q: Why is authentication inventory important?

A: Authentication inventory is important because it helps organizations protect themselves from credential stuffing and phishing attacks. By having a complete and accurate inventory of all points of authentication, organizations can ensure that the right security protocols are in place and that any suspicious activity related to authentication can be quickly identified and addressed.

Q: What steps should I take to properly inventory and secure my authentication points?

A: To properly inventory and secure your authentication points, you should: 1) Identify the different types of authentication used by the organization for remote access; 2) List all of the systems and applications that require remote access; 3) Document the type of authentication used for each system/application and any additional security measures or policies related to remote access; 4) Check with user groups to ensure that they use secure authentication methods and follow security policies when accessing systems/applications remotely; 5) Monitor access logs for signs of unauthorized access attempts or suspicious activity related to remote access authentication; 6) Regularly review and update existing remote access authentication processes as necessary to ensure accurate data.

Seek Out and Remove End-Of-Life Components

Just a quick reminder, at some point during each quarter, it is a good idea to enact a process to seek out and remove any end-of-life products in your environment. This is not only a best practice but a significant risk reduction measure as well. Make it an ongoing periodic process, and you’ve got a powerful weapon against threats and emerging issues stemming from end-of-life hardware, firmware, and software in your networks.

How to Search for End-Of-Life Products In Your Environment

The first step is to identify the devices, applications, and firmware that are no longer supported by their vendors. You can do this manually or with a tool. The next step is to determine which of those devices have been deployed in your network. Once you know where they are, you need to find them. There are several ways to search for these devices:

Use Network Inventory Tools

Network inventory tools such as Nmap and Nessus will allow you to scan your entire network to locate all of the devices on your network. These tools will also tell you what operating systems and versions of software/firmware are running on the device. If you’re using a vendor-specific tool, you’ll be able to see if there are any known vulnerabilities associated with the product in many cases.

Talk to Device and Application Owners

If you don’t already have a relationship with the owners of the devices and applications, then you should start building one now. It’s important to get to know the people who own the devices and applications so that you can ask questions about how they use the devices and applications. You may even want to consider getting an end-of-life security policy together for the organization so that you can make sure everyone understands the risks of end-of-life components.

Once you have discussed the issues with the owner, remove the component if possible. Otherwise, add it to a list of components to look for workarounds or replacements. Many organizations that can’t manage to replace an end-of-life component either place it in a low trust network zone, front-end it with firewalls or ACLs, and increase monitoring and detection of the assets involved. Of course, the component should be reviewed quarterly until it can be removed from service.

Doing this process every quarter will increase your networks’ overall stability and trust worthiness, plus reduce risk and management headaches. It’s well worth your time and an effective part of an overall risk management strategy.

How Do I Know If My Company Needs a Risk Management Policy?

Risk management policies protect companies against financial losses due to various risks. These risks include legal issues, employee misconduct, environmental hazards, etc.

A company may implement a risk management policy to minimize these risks. However, several questions should be asked before implementing such a policy.

What Are the Risks That Could Lead to Financial Losses?

Many types of risks can lead to financial losses. Some examples include:

• Legal issues

• Employee misconduct

• Environmental hazards

• Product liability

• Cybersecurity threats

• Data breaches

• Other

It is important to understand what type of risk your company faces. For example, if your company sells products online, you will face cyber security risks.

Are There Any Existing Policies?

Before deciding whether or not to adopt a risk management policy, it is important to determine whether any existing policies cover the risks your company faces.

For example, if your company has an insurance policy, then you may not need to implement a separate risk management policy.

However, if your company does not have an insurance policy, then it is necessary to consider implementing a risk management policy.

Is Implementing a New Policy Worth It?

Once you know what type of risks your company faces, it is time to decide whether or not to implement a risk management plan.

Some companies feel that they do not need a risk management plan because their current policies already address their risks. However, this decision should be made carefully.

If your company does not have a formal risk management policy, then it is possible that some of the risks your company faces could go unaddressed. This means that the risks could become more significant problems down the line.

In addition, if your company decides to implement a risk management program, it is crucial to ensure that the program covers all the risks your company faces, including those currently unaddressed.

Do Your Employees Understand What Is Being Done?

When implementing a risk management plan, it is vital to ensure employees understand what is being done.

This includes explaining why the risk management plan was implemented, how the plan works, and what steps must be taken to comply.

The goal here is to ensure that employees understand your company’s risks and how the risk management plan helps mitigate them.

Will the Plan Be Cost-Effective?

Finally, it is essential to evaluate whether or not the risk management plan will be cost-effective.

Cost-effectiveness refers to the amount of money saved compared to the costs incurred.

For example, suppose your company spends $1 million per year to insure its assets. In addition, suppose that the risk management plan saves $500,000 per year. Then, the risk management plan would be considered cost-effective if it saves $500,000 annually.

In this case, the risk management plan is cost-effective because it saves $500,00 annually.

However, if the risk management plan only saves $100,000 per year, then the plan is not cost-effective.

In Conclusion

As discussed above, there are many reasons to implement a risk management strategy.

These strategies can help your company avoid potential financial losses caused by certain risks.

In addition, implementing a risk management plan can make your company more efficient and productive.

 

A Cynefin Risk Management Use Case

Lately, I have been working on using the Cynefin framework to help a client with supply chain risk management. I’m not going to dig into the specifics here, but I wanted to share a quick workflow that we used during this process that has been very useful for us.

Risk Matrix

First, we built a risk matrix for supply chain risk. Basically, there are a number of these available via the various search engines. We took some of the most common ones and tore them down to commonalities, then built them into our matrix. We turned this into a simple spreadsheet.

Heat Mapping

Next, once we had our risk matrix, we did an exercise where we heat mapped the various risks, scoring them high/medium/low subjectively. This gave us an excellent tool to monitor our situation and communicate it with our stakeholders.

Applying Cynefin

Next, we mapped all of the high risks into the cynefin framework by researching the present state of each, whether best practices were available and relevant, being developed, or still in the experimental stage. This gave us a good idea of which problems we could simply focus on using known techniques and skills against, which ones we needed to take existing decent practices and optimize them, and which problems we needed to experiment with solutions for.

Sharing and Feedback

Overall, the exercise took around an hour to complete once we compiled the basic templates and completed the risk matrix research. For those of you facing complex risk management problems, this workflow might assist. Let me know on social media (@lbhuston) if it provides any help or if you have suggestions and feedback. Thanks for reading!

Preparing for the End of SMS Authentication

Over the last several years, wealth management/asset management firms have been integrating their systems with banking, trading and other financial platforms. One of the largest challenges wealth management firms face, from a technology standpoint, is managing multi-factor authentication when connecting to the accounts of their clients. In the coming year to eighteen months, this is likely to get even more challenging as SMS-based authentication is phased out. 

Today, many financial web sites, applications and phone apps require the use of SMS one-time security verification codes to be sent via text to the user. This usually happens once the user has entered their login and password to the system, after which it triggers the credential to be sent to their mobile phone number on record. The user then inputs this code into a form on the system and it is verified, and if correct, allows the user to proceed to access the application. This is called two factor authentication/multi-factor authentication (“MFA”) and is one of the most common mechanisms for performing this type of user authorization.

The problem with this mechanism for regulating sign ins to applications is that the method of sending the code is insecure. Attackers have a variety of means of intercepting SMS text messages and thus defeating this type of authentication. Just do some quick Google searches and you’ll find plenty of examples of this attack being successful. You’ll also find regulatory guidance about ending SMS authentication from a variety of sources like NIST and various financial regulators around the world. 

The likely successor to SMS text message authentication is the authenticator app on user mobile devices and smartphones. These authenticator apps reside in encrypted storage on the user’s phone and when prompted, provide a one-time password (“OTP”) just like the code sent in the text message. The difference is, through a variety of cryptographic techniques, once the application is setup and  the settings configured, it doesn’t need to communicate with the financial platform, and thus is significantly more difficult for attackers to compromise. Indeed, they must actually have the user’s device, or at the very least, access to the data that resides on it. This greatly reduces the risk of interception and mis-use of the codes in question, and increases the security of the user’s account with the financial institution.

This presents a significant problem, and opportunity, for wealth management firms. Transitioning their business processes from integrating with SMS-based authentication to authenticator apps can be a challenge on the technical level. Updates to the user interaction processes, for those firms that handle it manually, usually by calling the user and asking for the code, are also going to be needed. It is especially important, for these manual interactions, that some passphrase or the like is used, as banks, trading platforms and other financial institutions will be training their users to NEVER provide an authenticator app secret to anyone over the phone. Attackers leveraging social engineering are going to be the most prevalent form of danger to this authentication model, so wealth management firms must create controls to help assure their clients that they are who they say they are and train them to resist attackers pretending to be the wealth management firm. 

Technical and manual implementations of this form of authentication will prove to be an ongoing challenge for wealth management firms. We are already working with a variety of our clients, helping them update their processes, policies and controls for these changes. If your organization has been traditionally using SMS message authentication with your own clients, there is even more impetus to get moving on changes to your own processes.

Getting ROI with ClawBack, our Data Leak Detection Platform

So, by now, you have likely heard about MicroSolved’s ClawBack™ data leakage detection engine. We launched it back in October of 2019, and it has been very successful among many of our clients that have in-house development teams. They are using it heavily to identify leaks of source code that could expose their intellectual property or cause a data breach at the application level.

While source code leaks remain a signficant concern, it is really only the beginning of how to take advantage of ClawBack. I’m going to discuss a few additional ways to get extreme return on investment with ClawBack’s capabilities, even if you don’t have in-house developers.

One of the most valuable solutions that you can create with ClawBack is to identify leaked credentials (user names and passwords). Hackers and cyber-criminals love to use stolen passwords for credential-stuffing attacks. ClawBack can give you a heads up when stolen credentials show up on the common pastebin sites or get leaked inadvertantly through a variety of common ways. Knowing about stolen credentials makes sense and gives you a chance to change them before they can be used against you. 

We’ve also talked a lot about sensitive data contained in device configurations. Many potentially sensitive details are often in configuration files that end up getting posted in support forums, as parts of resumes or even in GITHub repositories. A variety of identifiable information is often found in these files and evidence suggests that attackers, hackers and cybercriminals have developed several techniques for exploiting them. Our data leak detection platform specializes in hunting down these leaks, which are often missed by most traditional data loss prevention/data leakage prevention (DLP)/data protection tools. With ClawBack watching for configurations exposures, you’ve got a great return on investment.

But, what about other types of data theft? Many clients have gotten clever with adding watermarks, unique identity theft controls, specific security measures and honing in on techniques to watch for leaked API keys (especially by customers and business partners). These techniques have had high payoffs in finding compromised data and other exposures, often in near real time. Clients use this information to declare security incidents, issue take down orders for data leaks and prevent social engineering attackers from making use of leaked data. It often becomes a key part of their intrusion detection and threat intelligence processes, and can be a key differentiator in being able to track down and avoid suspicious activity.

ClawBack is a powerful SaaS Platform to help organizations reduce data leaks, minimize reputational risk, discover unusual and often unintentional insider threats and help prevent unauthorized access stemming from exposed data.
