The oil and gas industry or also called the hydrocarbons sector chain corresponds to the set of economic activities related to exploration, production, transport, refining or processing and marketing of non-renewable natural resources known as hydrocarbons (organic material composed mainly of hydrogen and carbon), this set is also made up of the regulation and administration of these activities.

The value chain typically consists of three major areas; (a) exploration and production – upstream, (b) Transport – midstream, and (c) Refining and Marketing – downstream.

The hydrocarbon industry is generally highly regulated, often with price controls and is often the government of ownership and operation. Typically, many of the facilities involved in each of the industry’s processes can come to be considered critical infrastructure and therefore of national interest. This classification should be determined as a result of the criticality assessment using appropriate assessment methods, techniques and models. Suppliers of industrial automation, security, and service systems in conjunction with hydrocarbon operators must ensure compliance with security and cybersecurity standards, such as ISA/IEC-62443, NIST 800-53/82, IEC-61511, API, NPFA, and others. Keeping up with rules and regulations is a challenge.

Strategies and solutions based on information security technologies and perimeters are not enough to protect against all modern threats against electrical infrastructures. Industrial cybersecurity requires the protection of physical assets, i.e. the domain of physical security. Many programmable logic controllers (PLCs) and controllers for feed water pumps, feed water, valves, furnaces, boilers, turbines, generators, and capacitors are vulnerable due to the lack of built-in cryptographic controls, including: multi-factor authentication, secure boot, secure update, and encrypted secure communications.

In operational technology (OT) environments, risk is measured in terms of industrial safety and system availability. While data privacy is important, often human physical security, industrial process safety, environmental stewardship, and uptime drive the security needs of plants and large SCADA systems.

Most Common Security Risks to Oil & Gas Industries

Ransomware Attacks: Disrupt operations by encrypting critical systems. High-profile example: the Colonial Pipeline attack, which halted fuel distribution across the U.S. East Coast.

Phishing & Social Engineering: Entry point for most ransomware and credential theft. Exploits human error to bypass technical defenses.

Industrial IoT (IIoT) Vulnerabilities: Smart sensors and remote monitoring expand the attack surface. Many IIoT devices lack robust security controls.

Legacy Systems & Patch Gaps: Outdated SCADA and DCS platforms are common. Often incompatible with modern security tools, making patching difficult.

Supply Chain Attacks: Compromised third-party software or hardware introduces hidden threats. Attackers may exploit firmware updates or vendor access.

Insider Threats: Employees or contractors with privileged access may intentionally or accidentally cause harm. Often overlooked in risk assessments.

Distributed Denial-of-Service (DDoS): Overloads systems to disrupt operations or distract from deeper intrusions. AI-driven DDoS attacks are becoming more sophisticated.

Remote Access Exploits: VPNs and remote desktop tools are often misconfigured. Especially risky in offshore or unmanned facilities.

Some Strategic Mitigation Approaches

• Adopt ISA/IEC-62443 for OT cybersecurity lifecycle management.
• Segment IT and OT networks with strict access controls.
• Implement continuous monitoring (SIEM, IDS/IPS).
• Train personnel on phishing and incident response.
• Vet third-party vendors and require SBOMs (Software Bill of Materials).
• Develop and test incident response plans regularly.
