Control Engineering 2015 Cyber Security Study

Yesterday I posted a review of the recent SANS State of Industrial Control Systems Survey.  You can find that posting here.

Today I'd like to tell you about another interesting and equally disconcerting survey about the status of today's industrial control system security posture.

Each year Control Engineering Magazine conducts a survey of its readers to evaluate cyber security implementation, resources and training for industrial control systems.  Their 2015 Cyber Security report was issued this June.  A summary of the study posted by Control Engineering is located here.


The Control Engineering report is essentially in presentation format and has a collection of graphs and data relative to the data collected.  It is a pretty easy and quick read and offers similar data to the SANS Survey.

Statistics and Findings

The Control Engineering analysis included data collected from 284 respondents in the first quarter of 2015.  The report includes the following summary findings:

1.  Threat Levels:  47% of respondents perceive their control systems to be "moderately" threatened by cyber attacks.  25% say theirs is "highly" threatened and 8% are at the "severe" threat level.

2.  Most Concerning Threat:  Their responses included:

  • 35% view the most concerning threat is malware from a random source
  • 18% worried about loss of intellectual property
  • 8% fear attacks from "hacktivists" with political or environmental agendas.
3.  Most Vulnerable System Components:  The components of most concern include:
  • Connections to other internal systems (SANS is similar)
  • Computer assets running commercial operating systems (Same as SANS)
  • Network devices
  • Wireless communication devices and protocols
  • Connections to the field SCADA networks
4.  Vulnerability Assessments:  39% of those surveyed said their last vulnerability assessment was performed within the last six months (Good!); while 16% have never executed one (Not So Good).

5.  Publicly Reporting Incidents:  66% of those surveyed say publicly reporting cyber-related incidents would benefit the industry.  36% agree that the biggest problem with public reporting is the fear of losing consumer confidence.

6.  Resources Used to Monitor Control System Cyber Security Events:
  • Anti-virus software (99%)
  • Network logs (89%)
  • Firewall logs (89%)
  • Intrusion Detection/Prevention (84%)
  • Whitelisting (76%)
Overall....

Overall this is a useful survey to examine and as I noted for the SANS ICS Security Survey, these reports should be reviewed and digested by security professionals responsible for ICS security and shared with their executive management to show them that security is a concern and should be theirs, too.

State of Industrial Control Systems Security - A SANS Survey

This month the SANS Institute published its annual State of Security in Control Systems Today.  The results were prepared by Messrs. Derek Harp (SANS) and Bengt Gregory-Brown (Sable Lion Ventures LLC).



You can download the report from the SANS Reading Room at:  https://www.sans.org/reading-room/whitepapers/analyst/state-security-control-systems-today-36042 

Some Thoughts...

The report is a quick and useful read.  I'd highly recommend that not only ICS Security Professionals read and digest this report but also it be shown to the skeptical executives in their organization.

So, here are some key bullets gleaned from my read:

  • Top four concerns by those surveyed include:
    • Ensuring reliability and availability (68%)
    • Lowering risk/improving security (40%)
    • Preventing damage (28%)
    • Ensuring health and safety (27%)
  • Rapid detection of security incidents on ICS is key because the longer the breaches remain unknown, the greater the potential impact.
  • The integration of IT into control system networks was chosen by 19% of respondents as the single greatest threat vector.  The top three threat vectors were a) External Threat, b) Internal Threat, and c) Integration of IT into the Control System Networks.
  • 74% of respondents believe that their external connections are not fully documented.  (Ugh!)  Simply identifying and detailing connections and attached devices in a network is a key step to securing it.
  • Another challenge highlighted in the survey is a lack of visibility into control system equipment and network activity.  Thus this inhibits progress in securing assets and decreases activity in accuracy of self-evaluations.
Read the Margin Notes!

One editorial and formatting aspect of the report I liked was inclusion of marginal notes called TAKEAWAYs.  These notes are useful helpful ideas for the ICS security person to implement -- or at least consider -- when trying to protect their ICS systems.  A few examples of the TAKEAWAYs are:
  • Know what is normal.  Lack of visibility into control system networks is one of the greatest barriers to securing these resources.  Without awareness of normal communications and activity, it's impossible to properly evaluate or improve security of assets.  Operations and security staff must be able to visualize and verify normal network operations to detect and assess possible abnormalities and respond to potential breaches.
  • Gain visibility into control system networks.  Map all devices, physical interconnections, logical data channels and implemented ICS protocols among devices, including read coils, write registers, scans and time stamps.  Establish a fingerprint of normal control network activity and communication, including communication patterns, schedules and protocols.  Then, establish device logging, strict change management and automated log analysis based on your baseline data.
  • Integrate security into procurement and decommissioning processes.  Establishing security of software or devices is cheaper, easier and more effective prior to deployment.  The burden of maintaining security is lighter when you start from a secure state.  And, security should be included in the decommissioning and removal of devices to avoid opening serious vulnerabilities.
Again, a great job by SANS, Derek and Bengt!  Take the time to download and read this report and take advantage of the ideas to improve the security of your ICS networks.

Useful CIKR Resources

This Blog is focused on offering the reader information on two very useful resources focused on Critical Infrastructure and Key Resources (CIKR).  And, because of the George Mason Monthly CIP Report, I was informed about another European-centric CIKR resource the student and professional may be interested.

GEORGE MASON UNIVERSITY - MONTHLY CIP REPORT


Each month the George Mason University School of Law, Center for Infrastructure Protection and Homeland Security, publishes a newsletter focused on a different sector of CIKR.  This past month was on International Issues.  (BTW: The Center is moving to the School of Business in the next few months.)

You can subscribe to The CIP Report at no charge by going to this LINK.

You can visit the George Mason team at:  http://cip.gmu.edu/the-cip-report/   (The page view is below:)


Each month I look forward to this newsletter which is really more like a Journal focused on Critical Infrastructure Protection issues facing the US as well as globally.  As a CIKR professional you should benefit from the contemporary commentary in these monthly analyses.

(PS: The format is changing from a PDF to more of a web-based approach; however, the publication will still be sent out monthly.)

CIPEDIA (C): A CRITICAL INFRASTRUCTURE PROTECTION AND RESILIENCE RESOURCE

This month the immediate benefit from The CIP Report is an article prepared by three very notable European experts in the field of critical infrastructure and resilience.  The article is prepared around the CIPedia (www.cipedia.eu) web site which is a "...Wiki-based body of common knowledge for the wide international community of critical infrastructure (CI) protection and resilience stakeholders such as policy makers, researchers, governmental agencies, emergency management organizations, CI operators and even the public."

CIPedia Home Page www.cipedia.eu

According to the article in The CIP Report the CIPedia is developed within the European Critical Infrastructure Preparedness and Resilience Research Network (CIPRNet) project. 

Essentially, CIPedia is an international glossary on CIKR information.  CIPedia went public in mid-2014.

Of note, CIPedia is more than just a glossary -- as a CIKR portal it provides access to a list of CIP-related conferences, a table with web pointers to CIKR sector-specific glossaries and a pointer to the CIP bibliography.

Below is a screen shot of the CIPedia user links (left hand column).  You can see the links offer some more depth into other CIP-related areas:


CONCLUSION

If you are involved with Critical Infrastructure as a student or policy professional you will probably find the George Mason monthly report very useful and timely.  Secondly, access to the CIPedia and to the CIPRNet will increase your access to new documents and papers on CIKR from an European perspective.  For myself, just wandering around the sites for a few minutes surprised me at some of the work being done in Europe on cascading events studies, as an example.

Take the time to subscribe to The CIP Report and be sure to save the links to the CIPedia and CIPRNet.

New ICS Primer from ISACA

Industrial Control Systems (ICS) security continues to gain momentum and awareness in the cyber community.  ISACA has recently published its own version of ICS security awareness (cover of the document is below).



ISACA has published Industrial Control Systems: A Primer for the Rest of Us which can be obtained for no charge (registration is required) at www.isaca.org/ics 

If you are not familiar with ISACA (www.isaca.org) it has been around since 1969 and has about 115,000 constituents in 180 countries.  You may recognize ISACA as supporting COBIT and also the Certified Information Systems Auditor (CISA) and Certified Information Security Manager (CISM) certifications.

As you glance through the 19-page document you will recognize most of the graphics used come from either NIST 800-82, Guide to Industrial Control Systems (ICS) Security by Keith Stouffer, et al, or adapted from the ICS-CERT Advisories located at: https://ics-cert.us-cert.gov/advisories-by-vendor

One graphic that I especially liked was on page 13, Figure 7, showing a mind-map of Cybersecurity Threat Agents developed by our friends at the European Union Network and Information Security Agency (ENISA).  A copy of the graphic is below and can also be located at http://www.enisa.europa.eu/activities/risk-management/evolving-threat-environment/enisa-threat-landscape/enisa-threat-landscape-2014
























So, the good news is we have another primer to pass along to our bosses and IT managers/technicians  to help them better understand what ICS security involves.  There are a few good ideas in the document such as a list of ICS Components (Pages 4-5) and other references back to the NIST 800-82 document for more details.

A Humorous View of our Infrastructure Crisis -- I think!

For those of you who have followed this Blog these past few years you'll know that I'm very passionate about the state of the country's -- let alone world's -- infrastructure.  In particular the US infrastructure grade from the American Society of Civil Engineers remains around a D+.....a failing grade for most schools!

Well, yes, this is a crisis; however, John Oliver of Last Week Tonight on HBO recently offered a thought-provoking and (sadly) quite humorous review of the state of the US infrastructure and how even our politicians are simply not paying attention.

https://www.youtube.com/watch?v=Wpzvaqypav8&feature=youtu.be&t=4m32s

The link to the You Tube video of Oliver's 21-minute essay is:


Please enjoy...then write a letter to your Congressman/woman and demand some attention (and funding) to repair and sustain our infrastructure.

Thanks!

Energy Infrastructure - Major Changes Needed

Today the Obama Administration released a "first-ever" Quadrennial Energy Review.  This report is the result of President Obama's order on January 9, 2014 for the performance of this examination of the country's energy infrastructure.  The President's initiative was based on the President's Climate Action Plan and in response to a 2010 recommendation by the President's Councils of Advisers on Science and Technology.  A White House Task Force comprising 22 Federal agencies were assigned to develop the QER.



This particular release is supported by some excellent commentary and documents at the following sites:


  • Washington Post Article by Chris Mooney (Link)
  • Department of Energy Quadrennial Energy Review Web Page (Link)
  • Quadrennial Energy Review Fact Sheet (10 Pages) (Link)
The actual report is 348 pages long and the chapter organization is:
















The report included the following segments of energy infrastructure for this analysis:



As with most reviews of our country's energy infrastructure the statistics are daunting.

Some noted include:

  • 2.6M miles of interstate and intrastate pipelines
  • 640,000 miles of electric transmission lines
  • 414 natural gas facilities
  • 330 ports handling crude and refined petroleum products
  • 140,000+ miles of railways handling crude petroleum
And, of course, as observed in numerous other reports (such as the American Society of Civil Engineers (ASCE) Report Card) "...there has been a lack of timely investment in refurbishing, replacing, and modernizing components of infrastructure that are simply old or obsolete."

Some of the key findings highlighted on Page 25 of the report include:
  • Mitigating energy disruptions is fundamental to infrastructure resilience.
  • Transmission, Storage and Distribution (TS&D) infrastructure is vulnerable to many natural phenomena.
  • Threats and vulnerabilities vary substantially by region.
  • Recovery from natural gas and liquid fuel system disruptions can be difficult.
  • Cyber incidents and physical attacks are growing concerns.
  • High-voltage transformers are critical to the grid..
  • Assessment tools and frameworks need to be improved..
  • Shifts in the natural gas sector are having mixed effects on resilience, reliability, safety, and asset security.
  • Dependencies and interdependencies are growing.
  • Aging, leak-prone natural gas distribution pipelines and associated infrastructures prompt safety and environmental concerns.
Finally, one of the graphics in this report was fascinating.  It included a chart showing the "...billion dollar disaster event types by year..."  Not a purely energy-centric issue but certainly a demonstration of the challenges faced by energy infrastructure.

   If If you are an "infrastructure junkie" like me, this is a terrific report to digest and for our country's energy leadership to act upon.
