ISA99 Committee

The International Society of Automation (ISA) Committee on

Security for Industrial Automation & Control Systems

Almost 900 members from around the world

4


Our Scope

“… industrial automation and control systems whose compromise

could result in any or all of the following situations:

– endangerment of public or employee safety

– environmental protection

– loss of public confidence

– violation of regulatory requirements

– loss of proprietary or confidential information

– economic loss

– impact on entity, local, state, or national security”

5


Industry Contribution and Application

• Reflects expertise from many sectors, including:

– Chemical Processing

– Oil and Gas

– Food and Beverage

– Energy

– Pharmaceuticals

– Water

– Manufacturing

– ICS suppliers

ISA99 and ISA/IEC 62443

• ISA/IEC 62443 is a series of standards being developed by two

groups:

– ISA99 ANSI/ISA-62443

– IEC TC65/WG10 IEC 62443

• In consultation with:

– ISO/IEC JTC1/SC27 ISO/IEC 2700x

Requirements


Zones and Conduits

• A means for defining…

– How different systems interact

– Where information flows between systems

– What form that information takes

– What devices communicate

– How fast/often those devices communicate

– The security differences between system

components

• Technology helps, but architecture is more

important

15


Security Levels

16

Protection against…


Maturity Assessment

• A means of assessing capability

• Similar to Capability Maturity

Models

– e.g., SEI-CMM

• An evolving concept in the

standards

– Applicability to IACS-SMS

20


Security and Safety

• Safety is much of the reason for

security

– Presenting consequences

• Much to be learned from the safety

community

• Collaboration

– ISA99-ISA84 joint effort

– IEC TC65 work group 20

– ISA Safety and Security Division

18


Foundational Requirements

• FR 1 – Identification & authentication control

• FR 2 – Use control

• FR 3 – System integrity

• FR 4 – Data confidentiality

• FR 5 – Restricted data flow

• FR 6 – Timely response to events

• FR 7 – Resource availability
