As IoT networks expand across industries such as healthcare, automotive, and manufacturing, securing access to these devices has become more complex and crucial.

Privileged Access Management (PAM) is emerging as a cornerstone of IoT security, ensuring that only authorised individuals and devices can access critical systems. This article explores why PAM is essential in IoT environments, examining the specific challenges IoT devices present, the unique features of Device Authority’s PAM solutions, and real-world applications where PAM safeguards IoT infrastructure.

What is Privileged Access Management (PAM) in IoT?

Privileged Access Management (PAM) is a cybersecurity framework designed to control and secure access to critical systems by managing “privileged” accounts. In traditional IT settings, PAM restricts high-level access to servers, databases, and sensitive data, preventing unauthorised users from gaining entry. By limiting access based on the principle of “least privilege,” PAM significantly reduces the potential damage a cyber attacker can inflict.

As IoT ecosystems grow, PAM is becoming indispensable for IoT environments. IoT devices often operate in vulnerable locations, handle sensitive data, and connect across decentralised networks, making secure access a priority. These interconnected devices pose significant vulnerabilities and security risks, as their interconnectivity can be exploited by attackers.

Implementing PAM in IoT networks ensures that each device and user only has the permissions they need, minimising cyber risk across the system. From a security perspective, understanding and managing these risks is crucial for effective privileged access management and maintaining compliance within interconnected environments.

Understanding Privileged Access Management

Privileged Access Management (PAM) is a critical security practice that involves managing and controlling access to sensitive resources, systems, and data within an organization. By implementing PAM, organizations can prevent unauthorized access, reduce the risk of cyber-attacks, and ensure compliance with regulatory requirements.

PAM solutions are designed to identify and manage the people, processes, and technology that require privileged access. This involves specifying policies that apply to privileged access and supporting capabilities such as automated password management and multifactor authentication. By doing so, PAM ensures that only authorized users can gain access to sensitive resources, thereby safeguarding the organization’s critical assets.

The Risks of Unmanaged Privileged Access

Unmanaged privileged access poses significant risks to an organization’s security and compliance. When privileged access is not properly managed, it can lead to credential theft, lateral movement, and unauthorised access to sensitive resources. This can result in financial losses, reputational damage, and regulatory penalties.

Unmanaged privileged access can also lead to security breaches, data theft, and disruption of critical systems. Therefore, it is essential to implement a robust PAM solution to manage and control privileged access. By doing so, organizations can mitigate these risks and protect their sensitive resources from potential threats.

Unique PAM Challenges in IoT Environments

Implementing PAM in IoT environments presents unique challenges due to the distinct characteristics of interconnected devices and networks.

Unlike traditional IT systems, IoT ecosystems face access control issues that demand a tailored PAM approach:

  1. Remote Deployment: Many IoT devices are deployed in remote or unsecured environments, increasing the risk of unauthorised physical access. Without robust PAM, anyone with physical access to a device could potentially tamper with it, exposing the network to security breaches.
  2. Limited User Interfaces: Many IoT devices lack the interfaces typically used to verify and manage user access (e.g., no keyboard or display). PAM solutions in IoT must therefore automate and secure authentication processes, as relying on manual intervention is impractical.
  3. Continuous Monitoring Requirement: IoT devices operate around the clock, often performing critical functions. This constant operation makes it essential to have PAM tools capable of monitoring device status and access in real time to quickly detect and respond to potential security threats.
  4. Scale of Devices: IoT networks can involve hundreds or even thousands of devices, each requiring unique access rules. Managing privileged access across such a vast network demands scalable PAM solutions that can streamline access management while minimising security risks.

To address these challenges, Device Authority has developed IoT-specific PAM solutions that automate privilege assignments, ensure continuous device monitoring, and simplify access control across extensive IoT networks.

Key Components of a PAM Solution

A comprehensive PAM solution should include the following key components:

  1. Privileged Account Management: This involves managing and controlling access to privileged accounts, including password management, account creation, amendment, and deletion. By effectively managing privileged accounts, organizations can ensure that only authorized users have access to critical resources.
  2. Access Management: This involves controlling and managing access to sensitive resources, systems, and data, including remote access and third-party access. Effective access management ensures that only authorized users can gain access to sensitive information, thereby protecting the organization from potential security breaches.
  3. Session Monitoring: This involves continuously monitoring privileged sessions to generate reports and identify anomalies. By monitoring sessions in real-time, organizations can detect and respond to suspicious activities promptly, ensuring the security of their systems.
  4. Multifactor Authentication: This involves implementing multifactor authentication to ensure that only authorized users can access privileged resources. By requiring multiple forms of verification, organizations can add an extra layer of security to their access management processes.
  5. Least Privilege: This involves implementing a least-privilege policy to ensure that users only have access to the resources and systems necessary to perform their jobs. By limiting access to the minimum necessary, organizations can reduce the risk of unauthorized access and potential security breaches.
  6. Machine Identity Security: This involves managing and securing machine identities, including IoT devices and non-human identities. By securing machine identities, organizations can ensure that only trusted devices can interact with their systems, protecting against unauthorized access.
  7. Operational Technology: This involves managing and securing operational technology, including control systems and connected devices. By securing operational technology, organizations can protect their critical infrastructure from potential cyber threats.
  8. Security Teams: This involves providing security teams with the tools and visibility they need to manage and control privileged access. By equipping security teams with the right tools, organizations can ensure that they can effectively manage and secure privileged access across their systems.

By including these key components, a PAM solution can provide a robust and comprehensive security framework for managing and controlling privileged access. This ensures that organizations can protect their sensitive resources and maintain the integrity of their systems.
