Why Manufacturing Organizations Need Privileged Access Management for IIoT Security

Manufacturing organizations need Privileged Access Management (PAM) for Industrial Internet of Things (IIoT) security because it protects critical systems and devices by ensuring that only authorized users have access. IIoT refers to a network of connected devices that work together to collect and analyze data across industrial sectors to improve operational efficiency. As IIoT becomes increasingly integral to manufacturing, securing these connected systems is more important than ever. 

Understanding the risks of IIoT in manufacturing

IIoT devices in manufacturing come with several vulnerabilities, including weak passwords, inadequate security measures, lack of visibility within IIoT networks and potential risks to operations and safety. Securing IIoT systems is important to ensuring the safe and efficient operation of manufacturing environments. 

Default or weak passwords in IIoT devices

Many IIoT devices in manufacturing still rely on default and weak passwords, which make them vulnerable to exploitation. These devices often come with factory-set passwords that are rarely changed or are simply replaced with other weak passwords, creating an easy entry point for cybercriminals targeting manufacturing systems. Once an account is compromised, cybercriminals can steal sensitive data or disrupt operations. 

Inadequate security measures for IIoT device management

A lack of security measures is also a significant issue in IIoT device management. Many IIoT devices do not have proper security protocols integrated, such as patching, device authentication or encryption. Without regular security patching, devices aren’t updated with the latest security fixes, leaving them exposed to known vulnerabilities that cybercriminals can exploit. Additionally, the absence of device authentication and encryption weakens defenses, making it easier for unauthorized users to gain access to sensitive data and manipulate systems.

Lack of visibility and monitoring in IIoT networks

IIoT devices often lack adequate monitoring and logging mechanisms, which makes it difficult to detect suspicious behavior and unauthorized access. Without these features, security threats can go unnoticed, leaving sensitive manufacturing systems vulnerable to compromise. 

Potential impact on operations and safety

A single breach in IIoT security can trigger a chain of serious operational consequences in manufacturing, including production disruptions and data loss. In some cases, if safety systems are compromised, equipment malfunctions could put employees at risk of accidents or injuries. These breaches jeopardize both operational efficiency and workplace safety, potentially resulting in significant damage.

How PAM mitigates IIoT security risks in manufacturing

Implementing a strong PAM solution is essential in manufacturing, as it controls access to critical IIoT devices and prevents unauthorized users from accessing sensitive data. It enforces the principle of least privilege, strict access controls, real-time monitoring and strong password management. 

Enforces least privilege for users and service accounts in IIoT environments

PAM uses the Principle of Least Privilege (PoLP) to ensure that employees are granted only the minimum access required to perform their necessary tasks. This reduces the attack surface of the manufacturing organization by limiting the exposure of sensitive systems and data. It also minimizes the potential for privilege abuse and insider threats by ensuring that users cannot act outside their required scope. 

Controls privileged access to critical IIoT infrastructure

PAM controls and restricts access to critical IIoT related infrastructure so that only authorized users or service accounts can interact with these systems. It enforces strict access policies, such as Role-Based Access Control (RBAC), to ensure that no one has more access than needed to maintain secure operations. 

Prevents unauthorized access to IIoT devices and networks

PAM helps prevent unauthorized users or compromised service accounts from accessing or manipulating IIoT devices, such as sensors, actuators or robots within manufacturing environments. PAM’s access control features ensure that only trusted accounts can interact with critical IIoT devices. These devices collect and process sensitive data that provide real-time insights into operations, so securing access with PAM helps maintain data integrity and ensure efficient manufacturing processes. 

Enables real-time monitoring of privileged access to IIoT systems

PAM solutions offer real-time monitoring of privileged sessions and actions performed by users interacting with IIoT systems. Every action taken on these systems using privileged accounts is tracked and audited, enhancing security and user accountability. This level of monitoring helps quickly detect and address unauthorized access or suspicious behavior.

Automates and enforces password management for IIoT-related systems

PAM automates the management, rotation and enforcement of strong passwords for all types of accounts, including service accounts, user accounts and privileged accounts granted access to IIoT systems. Ensuring that passwords are regularly updated and meet strong requirements significantly reduces the risk of unauthorized access. Password management eliminates the possibility of cybercriminals exploiting weak or stale credentials to break into critical systems.
