1. An Insider’s Perspective on the NRC’s New Cyber Security Rule and Forthcoming Regulatory Guidance: Potential Impacts on Meteorology and Emergency Preparedness Programs Prepared by: Cliff Glantz, Phil Craig, and Guy Landine Pacific Northwest National Laboratory Richland, WA

2. Cyber security is a real concern The cyber threat landscape The new Nuclear Regulatory Commission (NRC) Cyber Security Rule -- 10 CFR 73.54 The new cyber security regulatory guide -- RG-5.71 Key Presentation Themes

3. The Concern… • Cyber security is an issue of grave national importance. • The NRC is concerned that a cyber attack can impact safety, security, and emergency response functions • NERC is concerned that a cyber attack can impact the ability of the electric grid “to keep the lights on”. 3

4. Cyber Threat Landscape Potential “Threat Agents” Hackers/crackers Insiders Organized crime Terrorists Espionage Cyber warfare

5. What is a Cyber Attack? A cyber attack can include a wide variety of computer-based events that could impact: Confidentiality: violate the security of data or software. Unauthorized access (internal or external) by those without appropriate authorization and “need to know”. Integrity: modify, destroy, or compromise data or software. This can involve the insertion of erroneous or misleading data or the unauthorized take-over of a system Availability: deny access to systems, networks, services, or data. CIA

6. Types of Threats Targeted/Untargeted Targeted threats are directed at a specific control system or facility Untargeted are focused on any computer with a given operating systems or commonly used software (e.g., Windows XP, Excel) Malicious/Inadvertent Malicious -- intending to do harm Inadvertent -- an accidental outcome Insider/Outsider Insider can be someone employed at the facility or a vendor Outsider can have no direct connection to the target, but may still have considerable knowledge Outsiders can exploit insiders with or without their explicit cooperation Direct/Indirect Direct involves an exploit on the targeted system Indirect involves exploiting a support system (e.g., power, cooling)

7. Examples of Potential Cyber Attacks A USB memory stick labeled as plant property is “dropped” in a parking lot at a local shopping center. It contains malware that would be installed on a company computer if someone good Samaritan plugs in the “lost” stick on a work computer to see who it belongs to. An internet connection (wired or wireless) or modem used to access meteorological data systems is hacked and the intruder gains system administrator control. A freeware meteorological program is downloaded to a business computer for legitimate purpose. It contains malware. The program is downloaded to a laptop used to adjust settings on meteorological and other monitoring instruments and impacts system performance. Plant Property

These are called critical digital assets. • Establish, implement, and maintain a cyber security program for the protection of the critical digital assets • Incorporate the cyber security program as a component of the physical protection program. 11

12. 10 CFR 73.54 – Program Design • The cyber security program must be designed to: • Implement security controls to protect the critical digital assets from cyber attacks • Apply and maintain defense-in depth protective strategies to ensure the capability to detect, respond to, and recover from cyber attacks • Mitigate the adverse affects of cyber attacks • Ensure the functions of critical digital assets are not adversely impacted due to cyber attacks. 12

13. 10 CFR 73.54 – More Program Requirements • The licensee shall: • Ensure that appropriate facility personnel, including contractors, are aware of cyber security requirements and receive the training necessary to perform their assigned duties and responsibilities. • Evaluate and manage cyber risks. • Ensure that modifications to critical digital assets are evaluated before implementation to ensure that the cyber security performance objectives are maintained. 13

14. 10 CFR 73.54 – Cyber Security Plan • Establish, implement, and maintain an effective cyber security plan that: • describes how the cyber security program will implement the Rule • Describes how the licensee will account for site-specific conditions that affect implementation • includes measures for incident response and recovery during and after a cyber attack. The plan must describe how the licensee will: • maintain the capability for timely detection and response to cyber attacks • mitigate the consequences of cyber attacks • correct exploited vulnerabilities • restore affected systems, networks, and/or equipment affected by cyber attacks. 14

15. 10 CFR 73.54 – Policies, Records, Etc. • The licensee shall: • develop and maintain written policies and implementing procedures to implement the cyber security plan. • make policies, implementing procedures, site-specific analysis, and other supporting technical information available upon request for NRC inspection • review the cyber security program as a component of the physical security program • retain all records and supporting technical documentation required to satisfy the requirements 15
