A shared drive, also known as a network drive, is a storage resource on a local network that can be accessed by multiple users or devices, facilitating file sharing and collaborative work within an organization. This centralized storage solution enables users to store, retrieve, and manage files across a networked environment, making it an essential component for efficient data management and collaboration.
Shared Drives in OT/IT Cybersecurity
In the context of Operational Technology (OT) and Information Technology (IT) cybersecurity, shared drives play a pivotal role in ensuring seamless operations across industrial and manufacturing environments. These drives often contain sensitive operational data, schematics, software configurations, and other critical information essential for maintaining production and operational integrity. As such, securing these shared resources against unauthorized access, data breaches, and other cyber threats is vital.
Shared drives must be properly managed and secured to prevent disruptions that could arise from cyber incidents. Implementing strict access controls, regular monitoring, and encryption are necessary measures to protect the integrity and confidentiality of data stored on these drives.
Importance for Industrial, Manufacturing & Critical Environments
In industrial, manufacturing, and critical infrastructure environments, shared drives enable teams to access and collaborate on large datasets and files, such as CAD drawings, project specifications, and operational logs, from various locations and departments. This operational efficiency is crucial in environments where real-time data access and collaboration can impact production schedules and safety protocols.
For example, in a manufacturing plant, engineers might use a shared drive to access and update machinery schematics or production schedules. In critical infrastructure, such as a power plant, operators might rely on shared drives for real-time monitoring data and incident response plans. The reliance on these shared resources underscores the importance of robust cybersecurity measures to protect against threats that could compromise these environments.
Relevant Standards
Several standards and frameworks provide guidance on securing shared drives as part of a broader cybersecurity strategy:
-
NIST 800-171: This standard outlines requirements for protecting controlled unclassified information (CUI) on non-federal systems, emphasizing access control and data protection measures applicable to shared drives.
-
CMMC: The Cybersecurity Maturity Model Certification includes practices and processes to safeguard Federal Contract Information (FCI) and CUI, which can be stored on shared drives in defense supply chain networks.
-
NIS2: The Network and Information Systems Directive 2 focuses on enhancing cybersecurity across the EU, with implications for network drives used within critical infrastructure sectors.
-
IEC 62443: This series of standards provides a framework for applying cybersecurity to industrial automation and control systems, including secure data storage and access management for shared drives.
Why It Matters
The use of shared drives in OT/IT environments necessitates a robust approach to cybersecurity, given the potential consequences of data breaches or unauthorized access. A compromised shared drive could lead to operational disruptions, intellectual property theft, or even physical damage in automated environments. By adhering to established cybersecurity practices and standards, organizations can significantly mitigate these risks, ensuring the integrity and availability of critical data and systems.
