Posted on March 8, 2023 by Brent Huston

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.

Authentication mechanisms are essential for organizations to protect their data and systems from unauthorized access. However, auditing these authentication mechanisms can be a challenge due to the complexity of the systems and the ever-evolving nature of cyber threats. This blog post will explore some of the challenges associated with auditing authentication mechanisms in organizations.

Challenges

1. Disparate Authentication Practices – As an auditor, you’re likely to come across a variety of authentication practices that can be difficult to manage. From different passwords to separate systems, disparate authentication requirements can be a major roadblock when auditing authentication mechanisms. To help reduce this challenge, organizations should establish strong identity and access management policies and ensure compliance with relevant regulations.

2. Staffing and Evidence Collection – The challenge of finding and retaining qualified staff who are knowledgeable and experienced in auditing authentication mechanisms is a common issue. Additionally, effective evidence collection is essential to successful audits, yet ensuring that meaningful data is gathered efficiently can be difficult.

3. Internal Controls – Auditors must ensure that the controls in place are sufficient to reduce risks associated with authentication processes. Weak access controls can lead to costly mistakes, potentially risking the organization’s data. Auditors should take the time to develop a detailed understanding of the organization’s internal controls and audit them on a regular basis against up-to-date and relevant threat models.

TLDR

This article discusses the challenges associated with auditing authentication mechanisms in organizations. It highlights three main issues: disparate authentication practices, staffing and evidence collection, and internal controls. Organizations should establish strong identity and access management policies to reduce the challenge of disparate authentication practices. Additionally, finding qualified staff and collecting meaningful evidence can be difficult tasks for auditors. Lastly, auditors must ensure that internal controls are sufficient to reduce risks associated with authentication processes.

PS – Make sure if you are performing such an audit that, you are checking your current practices against international standards, regulatory requirements, privacy rules, and best practice audit controls. Ensure that you are taking the essential steps to protect digital identity, providing strong access control policies and user controls. Reviewing the logging, and event detection capabilities and ensuring that both unauthorized access and successful authentications are being properly monitored in the event that forensic analysis is needed to respond to a security breach or other incident.

PSS – If you need a process for auditing your authentication points, you can find that here.

FAQ for the End of SMS Authentication

Posted on January 4, 2023 by Brent Huston

Q: What is the end of SMS authentication?

A: SMS authentication verifies user identity by sending a one-time code via text message to a user’s mobile phone number. With the rise of potential security risks, many financial websites, applications, and phone apps are phasing out SMS-based authentication and transitioning to authenticator apps that reside on user devices and smartphones.

Q: What are some of the potential security risks associated with SMS authentication?

A: Attackers have a variety of means of intercepting SMS text messages, thus defeating this type of authentication. This increases the risk of interception and misuse of the codes in question and decreases the security of the user’s account with the financial institution.

Q: What is an authenticator app?

A: An authenticator app is an application that resides in encrypted storage on the user’s device and, when prompted, provides 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 set up and the settings configured, it doesn’t need to communicate with the financial platform and thus is significantly more difficult for attackers to compromise.

Q: What are the steps for organizations to switch from SMS authentication to authenticator apps?

A: Here is a quick overview of what is needed:

1. Research and decide on an authenticator app that meets your organization’s needs. Most of the time, users can select their own apps, and the firm selects the libraries needed to support them. Open source and commercial solutions abound in this space now.

2. Update user accounts in each application and authentication point with the new authentication protocol and provide instructions for downloading and setting up the authenticator app.

3. Educate users on using the authenticator app, including generating one-time passwords (OTPs), scanning QR codes, etc.

4. Monitor user feedback and usage data over time to ensure a successful switch from SMS authentication to an authenticator app.

PS – Need a process for cataloging all of your authentication points? Here you go.

Inventorying Organization Authentication Points

Posted on January 2, 2023 by Brent Huston

Are you looking for threat-proactive ways to secure your enterprise? One of the best ways to do this is by inventorying all of the points of authentication within your organization. In this blog post, we’ll discuss the steps you need to take to properly inventory and secure your Internet-facing authentication points. While you should have a complete and accurate inventory of these exposures, starting the process with a focus on critical systems is a common approach.

Inventory Process

1. Identify the different types of authentication used by the organization for remote access (e.g. passwords, two-factor authentication). If possible, use vendor data to include cloud-based critical services as well.

2. List all of the systems and applications that require remote access within the organization. External vulnerability scanning data and Shodan are both useful sources for this information.

3. For each system/application, document the type of authentication used and any additional security measures or policies related to remote access (e.g., password complexity requirements). Vendor management risk data can be useful here, if available.

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 the continued security of organizational resources over the Internet.

Why This Is Important – Credential Stuffing & Phishing

Inventorying all of the points of authentication within an enterprise is essential as protection against credential stuffing and phishing attacks. Credential stuffing is a type of attack where malicious actors use stolen credentials to gain access to different accounts, while phishing attacks are attempts to acquire confidential information through deceptive emails or websites. In both cases, it is important that organizations have proper authentication measures in place to prevent unauthorized access. Inventorying all of the points of authentication within an organization can ensure that the right security protocols are in place and that any suspicious activity related to authentication can be quickly identified and addressed.

In addition, having a detailed inventory of all points of authentication can help organizations identify any weak spots in their security measures. This allows them to take steps to strengthen those areas and further protect themselves from potential credential stuffing or phishing attacks. By regularly reviewing and updating their authentication processes, organizations can ensure that their resources remain secure and protected from any malicious actors.

Lastly, ensure that you feed this inventory and the knowledge gained into your enterprise risk assessment processes, incident response team, and other security control inventories. Make a note of any security gaps identified during the inventory process and ensure complete coverage of the logs and other intrusion detection systems at each potential point of authentication. By following these steps, you can ensure that your enterprise remains secure and protected from any potential threats associated with credential stuffing and credential theft associated with common phishing attacks.
