Internet of Things (IoT) devices form the backbone of many modern businesses, facilitating operations, collecting valuable data, and enhancing efficiency. However, the widespread deployment of these devices creates numerous entry points for potential attackers. Without robust security measures, you risk exposing critical systems and sensitive information to malicious actors.

Why Is Secure Remote Access for IoT Devices So Important?

Secure remote access for IoT devices is a growing concern for your business. The connectivity and often inadequate security measures of IoT devices make them vulnerable to various cyberattacks, including unauthorized access, data breaches, and malware infections. 

IoT devices often operate in distributed environments and collect sensitive data, making them prime targets for cyberattacks. These attackers might manipulate device functions or cause major disruptions in operations. You must take steps to safeguard your business and customer data to ensure secure access that will protect against these threats.

Challenges of Securing IoT Devices

Securing IoT devices can be a challenge. In fact, 97% of organizations struggle to secure their IoT & connected devices. Many of these devices lack built-in security features, making them vulnerable to attacks. These devices are typically deployed in various environments, from industrial settings to smart homes, complicating the management and security processes.

Another significant challenge is the lack of standardized security protocols across different types of devices, leading to inconsistent security practices. IoT devices often operate with minimal processing power and memory, which restricts the implementation of advanced security measures. If you access IoT devices remotely over unsecured networks, you may expose them to interception and tampering. 

To address these issues, you need a security strategy that includes robust access control, continuous monitoring, and encrypted communication channels.

6 Strategies for Secure IoT Device Remote Access

Taking a strategic approach to securely access your IoT devices remotely will allow you to protect sensitive data and maintain system integrity. These strategies include: 

Strategy 1: Implement Zero Trust Architecture 

Adopting a Zero Trust Architecture involves a "never trust, always verify" approach that will allow you to access IoT devices remotely and securely. This model requires continuous authentication and authorization, ensuring that only verified users can access your devices. Use StrongDM to enforce strict identity verification and access controls, enhancing the security of your IoT network by requiring verification at every access point.

By implementing Zero Trust Architecture, you ensure that every access request undergoes rigorous verification, eliminating implicit trust based on network location or device. Zero Trust Architecture applies stringent security checks at each layer of your network, ensuring that both internal and external threats are mitigated effectively.

Strategy 2: Use Strong Authentication Methods

Strong authentication methods, such as multi-factor authentication (MFA), are vital for secure remote access to your IoT devices. MFA adds an extra layer of security by requiring users to provide multiple forms of verification before accessing devices. Leverage StrongDM to manage and enforce MFA policies seamlessly across all your IoT devices so only authorized users can access IoT devices remotely.

Multi-factor authentication significantly enhances security by combining:

  • Something you know (password)
  • Something you have (security token)
  • Something you are (biometric verification). 

These layers protect you so that even if one factor is compromised, unauthorized access remains unlikely.

Strategy 3: Secure Communication Channels

Encrypting all communication between IoT devices and control systems is essential to protect data in transit. Encrypted communication channels keep your data confidential and unaltered during transmission and prevent eavesdropping and tampering by malicious actors. 

By using protocols such as SSH, RDP, and HTTPS, you protect sensitive information from interception and manipulation. StrongDM provides reliable support for these protocols to safeguard the data transmitted between your devices and control systems.

Strategy 4: Centralize Access Management

Centralized access management will assist in maintaining a single source of truth for all IoT device access permissions. It also simplifies policy enforcement and auditing processes. StrongDM takes care of this for you so you can monitor and control access permissions from a unified platform. This reduces the risk of a breach and ensures compliance with security policies.

Centralizing access management with StrongDM allows you to:

  • Access IoT devices remotely
  • Easily grant and revoke access permissions Complete comprehensive audits
  • Track all access attempts
  • Identify potential security breaches 

StrongDM’s centralized platform provides a single interface for managing access controls, ensuring that all access decisions are consistent and based on up-to-date policies.

Strategy 5: Continuous Monitoring and Auditing

Implementing real-time monitoring and logging of remote access to IoT devices is essential for detecting and responding to security incidents promptly. Continuous monitoring allows you to track access patterns and identify anomalies that could indicate potential threats. 

Leverage StrongDM’s comprehensive logging and auditing capabilities to track and analyze access patterns with complete visibility of your entire environment, including IoT devices. You can also maintain detailed records of all access attempts, facilitating prompt detection and response to unusual behavior.

Strategy 6: Granular Access Controls

Defining and enforcing role-based access controls (RBAC) for IoT devices ensures that users have the minimum necessary access to perform their tasks. Granular access controls help minimize the attack surface by restricting access based on roles and responsibilities. 

These controls enable you to tailor access permissions to the specific needs of each user, reducing the risk of unauthorized attempts to access IoT devices remotely. You can use StrongDM to create detailed access policies to ensure that each user only has the access required for their specific role, enhancing the overall security of your IoT ecosystem. 

Best Practices for IoT Device Remote Monitoring

To properly access IoT devices remotely and monitor them, you need to establish some best practices. These include:

  • Update and patch management: Implement a robust update and patch management policy. IoT devices should receive software updates as soon as they are available to protect against known vulnerabilities.
  • Physical security measures: While often overlooked, physical security measures are a must for IoT devices. Ensure devices are housed in secure locations and physical access is restricted to authorized personnel only.
  • Data privacy protocols: Adopt stringent data privacy protocols to manage the data collected by your IoT devices. This includes data minimization practices, secure storage solutions, and clear data usage policies to ensure compliance with privacy regulations.
  • Employee training and awareness: Train employees on IoT security best practices and the specific security measures that apply to your IoT devices. Regular awareness sessions can help prevent accidental breaches and improve response times to security incidents.
  • Disaster recovery and response planning: Develop and regularly update a disaster recovery plan that includes steps for responding to IoT security incidents. This should involve data backups, system restorations, and communication strategies during a breach.
  • Third-party risk management: If your IoT systems interact with third-party services or vendors, it’s necessary to manage these relationships carefully. Conduct regular security audits of third-party vendors and ensure that their security practices align with your security standards.
  • Segmentation of network: Segment your network to ensure that IoT devices operate on a separate and secure network. This limits the potential for cross-device breaches and contains any security incidents within a controlled environment.
  • Legal and regulatory compliance: Stay informed about and comply with relevant legal and regulatory requirements that impact IoT security. This includes understanding sector-specific regulations that may affect how you deploy and manage IoT devices.
