Let's take a look at the features of 'NIST 800-82' highly influential in shaping OT security policies

-


Here’s a detailed breakdown of NIST Special Publication (SP) 800-82, titled Guide to Industrial Control Systems (ICS) Security:

NIST 800-82 Breakdown

Definition & Purpose
NIST SP 800-82 provides guidance on securing Industrial Control Systems (ICS), including SCADA (Supervisory Control and Data Acquisition), DCS (Distributed Control Systems), and PLCs (Programmable Logic Controllers). It helps organizations improve the security of OT (Operational Technology) environments.

Scope
  • Covers ICS security risks, threats, vulnerabilities, and mitigation strategies.
  • Applies to critical infrastructure sectors (energy, water, manufacturing, transportation, etc.).
  • Aligns with NIST Cybersecurity Framework (CSF) and NIST SP 800-53 for federal systems.
Key Requirements
  1. Security Architecture & Controls: Implement layered defense (Defense-in-Depth).
  2. Access Control & Authentication: Role-Based Access Control (RBAC), Multi-Factor Authentication (MFA).
  3. Network Security: Firewalls, Intrusion Detection Systems (IDS), network segmentation.
  4. System Hardening: Patch management, secure configurations, whitelisting.
  5. Incident Response: ICS-specific incident handling, logging, forensics.
  6. Physical Security: Protect access to ICS devices, control rooms, and critical assets.
  7. Security Testing & Assessment: Vulnerability scanning, penetration testing, and risk assessments.
Special Notes
  • Mandatory?: No, but widely referenced in U.S. government and industry regulations (e.g., NERC CIP, TSA Security Directives).
  • ICS systems differ from traditional IT: Real-time operations, availability-focused, safety-critical.
  • Third-party risks: Emphasizes vendor security management.
  • OT/IT Convergence: Provides strategies for integrating IT security into OT environments without disrupting operations.

Recap

  • NIST 800-82 is a best-practice guide, not a regulatory requirement, but it is highly influential in shaping OT security policies.
  • Focuses on protecting ICS from cyber threats while ensuring availability, reliability, and safety.
  • Aligns with other U.S. regulations (e.g., NERC CIP for power grids, TSA SD for pipelines).
  • Helps organizations identify and mitigate ICS-specific vulnerabilities while maintaining operational efficiency.

Don't confuse DCS, PLC and SCADA in front of OT specialists

DCS, PLC and SCADA are not the same. If you keep talking only about PLC security in front of the Oil&Gas industry executives where DCS is the main focus, they will not recognize you as a proper expert. We need to understand the characteristics of OT systems such as DCS, PLC, and SCADA accurately, also respect each OT culture uniquely and finally approach the sites in the right way. Don't be confused, here’s a clear and accurate explanation of DCS, PLC, and SCADA . 1. Distributed Control System (DCS) Concept A DCS (Distributed Control System) is an automated control system used for large-scale industrial processes that require continuous operation and high reliability. It consists of multiple controllers distributed throughout the system, which communicate with each other to manage complex processes. Key Features Used in large-scale, continuous processes (e.g., oil refineries, power plants). Decentralized control architecture with multiple controllers working together. Pr...

Image
A comprehensive list of 20 threat scenarios in OT security along with detailed descriptions and detection rules that can help identify and respond to these threats. This playbook-style table covers different types of attacks—from unauthorized access to insider abuse—with corresponding rules and indicators to alert security teams. # Threat Scenario Detailed Description Detection Rules & Indicators 1 Unauthorized Remote Access Attempt An attacker uses stolen or weak credentials to access OT networks remotely. - Log Analysis: Monitor VPN/RDP logs for unusual login times, geolocation mismatches, and failed/successful login bursts. - User Behavior Analytics (UBA): Alert on deviations from normal remote access patterns. - Anomaly Detection: Trigger an alert when a remote session is initiated from an unusual IP or geographic region. 2 Malware/Ransomware Infiltration in OT Network Malicious code is introduced into the OT network via compromised endpoints or phishing, potentially encr...

Let's create our own ICS Labs in the VMs: A Step-by-Step Guide Building an Industrial Control System (ICS) lab in a virtualized environment allows security researchers, engineers, and penetration testers to safely simulate industrial networks, study threats, and test security defenses. Below is a detailed step-by-step guide to creating an ICS lab , including HMI, EWS, PLC, and other critical components. 1. Lab Architecture Overview Key Components in an ICS Lab: HMI: Graphical interface for controlling industrial processes. Engineering Workstation (EWS): Used to configure PLCs and SCADA systems. PLC: Controls physical processes (e.g., motors, valves). SCADA System: Supervisory control and monitoring of ICS networks. Historian: Logs and stores process data for analysis. Networking Components: Virtualized switches, routers, and firewalls to segment ICS networks. Attacker Machine: Kali Linux or Metasploit for penetration testing. 2. Choosing the Virtualization ...
