what is an ics security roadmap
What is an ICS Security Roadmap?

A structured set of priorities, milestones and goals which address security requirements specific to Industrial Control Systems (ICS), over a 10 year timeframe

published roadmaps
Published Roadmaps

Energy Sector (revised Sep-11)

“The 2011 Roadmap takes the necessary steps to strengthen the security and reliability of our country’s electric grid, in a climate of increasingly sophisticated cyber incidents.”

“This update marks a continued effort by public and private energy sector stakeholders to reduce cyber vulnerabilities that could disrupt the nation's ability to deliver power and energy.”

why do we care
Why do we Care?

ICS are increasingly interconnected to other plant and business systems

ICS vendors continue to rapidly incorporate standard Information Technology into their products

These trends expose the ICS to modern malware threats

Potential consequences of an ICS cyber incident can include:

Reduction or loss of production at one site or multiple sites simultaneously;

Injury or death of employees;

Injury or death of persons in the community;

Damage to equipment;

Release, diversion, or theft of hazardous materials; and

Impact to company’s reputation in the community.

the risk is real
The Risk is Real!!

Federal agencies reported 30,000 incidents to US-CERT during fiscal yr 2009 [GAO report 6/16/2010]

>400% increase over what was reported in 2006 2010 CIP Survey conducted by Symantec

60% of cyber attacks were “somewhat” to “extremely” effective

Average cost of an attack was estimated at $850,000

Significant increase in Advanced Persistent Threat (APT)

Stuxnet signaled a paradigm shift in ICS cyber threats

Demonstrated that ICS are susceptible to increasingly sophisticated cyber-attacks

The “voice” of the sector on improvements to control systems security

Published September 2009

Following sign off by the

Chemical Sector Coordinating Council

A structured set of priorities spanning a 10 -year timeframespecific to needs ofIndustrial Control Systems (ICS) in the Chemical Sector

roadmap vision
Roadmap Vision

“In 10 years, the layers of defense for industrial control systems managing critical applications will be designed, installed and maintained, commensurate with risk, to operate with no loss of critical function during and after a cyber event.”

Scope

Industrial Control Systems (ICS) in chemical facilities that are part of the critical infrastructure

Possible implications for ICS vendors

Connection to other systems included if they impact ICS risk

developing a business case
Developing a Business Case

The protection of ICS from cyber security threats requires resources and personnel to plan, develop and implement needed security measures

Companies must develop a business case for investing in ICS security

A business rationale for justifying this investment is currently under development

Authored by the Industrial Control Systems Joint Working Group

Goal is to provide guidance for Developing a Business Case

a case for action
A Case for Action

The chemical industry dedicates immense time and resources toward ensuring the safety of its personnel, customers, and surrounding community; but in today’s environment of growing cyber threats, a Chemical plant is not safe unless its control systems are secure.

One of the trends emerging in the current environment of cost efficiencies, is the move from delivery of ICS on “proprietary” system platforms to “open” system platforms. These open platforms carry a greater level of cyber risk due to the rapid growth of cyber threats against them.

cset cyber security evaluation tool
CSET -Cyber Security Evaluation Tool

Available from the Department of Homeland Security

Assists organizations in protecting their key national cyber assets.

Developed under the direction of the DHS National Cyber Security Division (NCSD)

Developed by cyber security experts and with assistance from the National Institute of Standards and Technology.

This tool provides a systematic and repeatable approach for assessing the security posture cyber systems and networks.

Includes both high-level and detailed questions related to all industrial control and IT systems.

procurement language
Procurement Language

Department of Homeland Security: Cyber Security Procurement Language for Control Systems provides sample recommended language for control systems security requirements, including:

what can you do
What Can You Do?

Pick up a DVD & Case for Action to take with you

Review the information shared today

Bring this issue to the attention of your engineering & manufacturing management

Ask key questions about how your company is addressing ICS security

And as you begin…

tips for getting started
Tips for Getting Started

Ensure one person takes ownership of ICS security and is accountable.

Open the lines of communication between engineering, security, IT, process safety and manufacturing operations within your own company.

Conduct an audit of current ICS security measures and implement obvious fixes.

Follow-up with an ICS security vulnerability analysis (risk assessment).

tips for getting started1
Tips for Getting Started

Implement an ICS security management program that is integrated with existing company management systems for security, safety, quality, etc.
