Limitations of OEM Secure Remote Access Tools
In the second installment of this three-blog series on Secure Remote Access (SRA) we explore why using dedicated SRA tools is a better option than relying on OEM remote access solutions for Industrial Control Systems (ICS) environments.
In modern industrial environments, remote access to ICS environments is a necessity rather than a luxury. From energy grids to manufacturing plants, mine sites to airports, organizations rely on remote solutions to monitor and manage critical operations. However, the use of remote access tools provided by Original Equipment Manufacturers (OEMs), introduces unique security risks.
The Pitfalls of OEM Remote Access Tools
OEMs design and develop the hardware and software components used in ICS environments, and most of them offer built-in or optional remote access capabilities for maintenance and support. While these tools may offer functionality tailored to specific equipment, they often fall short in the critical area of cybersecurity and certainly become a cause for concern in a mixed-OEM environment. Here are some key challenges:
-
Lack of Robust Security Features: OEM remote access tools are primarily designed to provide ease of access for system support, not for long-term secure operation. These tools often lack essential security features such as multi-factor authentication (MFA), encryption, and proper auditing.
-
Inconsistent Security Standards: OEM tools vary significantly in terms of security measures, depending on the manufacturer. This inconsistency creates gaps in an organization’s security posture, making it difficult to implement standardized security policies across all connected devices.
-
Infrequent Updates + Patching: Some OEMs may not prioritize regular updates for their remote access tools, leaving them vulnerable to known exploits. When updates are released, they may not always align with an organization's patching schedule, causing delays and potential exposure to cyber threats.
-
Limited Control + Customization: Many OEM tools provide limited options for customization, forcing organizations to adapt their security practices to fit the constraints of the OEM system. This can result in security trade-offs that leave critical systems more vulnerable to attacks.
-
Vendor Dependency: By using OEM remote access tools, organizations become reliant on the vendor for security patches and support. If a vendor has weak security practices or slow response times, it can hinder the organization’s ability to respond to threats in a timely manner.
While OEM remote access tools may seem convenient, they often lack the critical security features needed for long-term safety. By opting for a more robust solution, you can ensure better security and scalability.
