Rising Cybersecurity Threats


CyberWar (InfoWar)


Aurora


Night Dragon

•  Recently published by McAfee

•  Activity designed to obtain sensitive data from targeted organizations in global oil and energy industries…


Night Dragon

•  Source appears to be China, but this is difficult to confirm exactly

•  Began Nov 2009, possibly as early as 2007

•  Techniques: –  Social engineering

–  Spear-phishing attacks

–  Exploitation of Microsoft Windows vulnerabilities

–  Microsoft Active Directory compromises

–  Remote administration tools (RATs)


Night Dragon

•  Harvesting sensitive competitive proprietary operations, and project-financing information for oil and gas field bids and operations

•  Controlled systems, then cracked accounts to move to more sensitive information/systems

•  Focus was on operational oil and gas field production systems and financial documents related to field exploration and bidding

•  In certain cases, the attackers collected data from SCADA systems


Stuxnet

•  First publicly disclosed control systems rootkit, but certainly wont be the last...

•  USB vector; focused on “air-gapped” networks

•  Highly sophisticated; infects everything, then rewrites PLC logic and hides

•  Undermines integrity of control system

•  Most regulations wouldn’t have stopped it

•  No 100% security against determined

adversary


SHODAN, ERIPP, ETC


SHODAN, ERIPP, ETC

Berkeley Cyclotron HMI images


There’s An App For That

•  “Get mobile access to your control system via an iPhone, iPad, Android and other smartphones and tablet devices. The Ignition Mobile Module gives you instant access to any HMI / SCADA project created with the Ignition Vision Module.”

Research and Disclosure

•  October 24, 2010, 12:39PM, Threat Post –  SCADA Vendors Still Need Security Wake Up Call

•  http://threatpost.com/en_us/blogs/scada-vendors-still-need-security-wake-call-102410

–  “Please don’t waste my time”

•  October 28, 2010: ICSJWG Seattle Meeting –  Invensys, IOActive, ICS-CERT presented on case study on

Wonderware vulnerability

•  Disclosure positions are hotly debated


From Obscurity To Novelty

•  Smart Meter hacking

•  Hacking cookbooks

•  Metasploit

•  Fuzzers

•  Supply chain attacks

•  Manuals available in all languages on Internet


Shiny Object

•  Shiny object for the mass media

•  60 minutes

•  Wall Street Journal, National Journal, CNN

•  Too many IT trade publications to name

•  Blockbuster films

•  Prime time television shows

•  Social Media (blogosphere, Twitter)


Economic Drivers

•  Recession economy brings unique challenges

•  Decreased participation working groups and conferences

•  Static or shrinking headcount; increased workload

•  Insider threat increases

•  Decreased spending on new equipment

•  Older products extended beyond intended lifespan

•  Security is expensive for customers and vendors


People Problem

•  Humans are the weakest link in any security system –  Passwords for candy; Social engineering

•  Humans are also the strongest link in any security system –  The Aware Person System (APS)

–  ICS culture shift is very slow, but can be very powerful

•  Danger: unskilled/untrained operators of power tools can cause significant damage –  Increasing complexity = training treadmill


People Solution

•  So you’ve bought all of the fancy cybersecurity gizmos… –  What about the skilled staff to use

them?

•  So you’ve put cameras in all critical sites… –  What about the staff to monitor and

respond?

•  An appropriate balance of skilled people and current technology must be used


Back In The Good Old Days

•  Pneumatic, electromechanical, analog

•  Telephone meant POTS or “bat phone”

•  No Internet

•  Less automation

•  Less complexity

•  Proprietary

•  Long life span


ICS Gen-X

•  Automation, more complexity

•  Internet Protocol (TCP/UDP/etc)

•  Data, more data and even more data

•  Processing power, memory, bandwidth = SPEED!

•  Interconnected business

•  Flat networks

•  COTS software and hardware

•  Increasingly shorter lifespans


Millennium Systems

•  Highly digital, highly complex

•  Highly interconnected, highly layered

•  Bitflocking, dynamic emergent behavior

•  New protocols

•  New interdependencies

•  Homogenization

•  Innovation treadmill; constant lifespan flux


Bigger, Better, Faster

•  ARRA and other “green” dollars are flowing

•  SCADA devices now come with a flash-webserver-WiMax-mesh-ZigBee-kitchensink

•  Mixing legacy and bleeding edge tech is difficult

•  Logical distance between kinetic endpoint and HMI is exponentially increasing; “hyperembeddedness”

•  Most (but not all) vendors put features first, security last; this will not change in the foreseeable future


Advantage: Attackers

•  Security approaches favor new installations, legacy environments are still vulnerable

•  Very difficult to replace/patch in-service devices

•  Stuxnet: game changer, sets the new bar - even when sophisticated attacks aren’t necessary

•  Organized crime will top Nation States and Non-Government Organizations (NGOs) as biggest threat

•  Welcome to the cyberarms race

Three Flavors

Business Systems Control Systems “Smart Grid”


Business IT Security

•  Typical approach: password, firewall, anti-virus, etc •  Protecting four key domains

1. Confidentiality – preventing unauthorized access to information

2. Integrity – preventing the unauthorized modification or theft of information

3. Availability – preventing the denial of service and ensuring authorized access to information

4. Non-Repudiation – preventing the denial of an action that took place or the claim of an action that did not take place

What Have You Seen?

•  Did cyber security appear in your filings and hearings?

•  How did this fit in your list of priorities?

•  What elements were most important? –  Privacy?

–  Reliability?

–  Cost?

–  Security Effectiveness?

–  Upgradeability as a solution or vulnerability?


Threat Sources

•  Inadvertent errors

•  Power system equipment malfunctions

•  Communication equipment failure

•  Deliberate malicious acts


Threat Types

•  Replay attacks

•  Indiscretions (leaks) by personnel

•  Brute force

•  Bypass controls

•  Man-in-the-Middle

•  Denial of Service

•  Resource Exhaustion


Nothing New Under The Sun

•  Mature security practices; highly refined –  Defense in Depth

–  Principle of Least Privilege

–  Segregation of Duties

–  Need to Know

–  Confidentiality, Integrity, Availability

•  No Silver Bullet, 100%, Total Security

•  Strong protection has never been easy, inexpensive or quick to implement

•  Tradeoff between functionality and security


Strategies for Defense In Depth

•  Governance, policy

•  Authentication

•  Authorization

•  Admission control

•  Encryption

•  Integrity checking

•  Auditing, detection


Defense In Depth: Example

•  NERC CIP Standards

– CIP-002 – Critical Cyber Asset Identification

– CIP-003 – Security Management Controls

– CIP-004 – Personnel & Training

– CIP-005 – Electronic Security Perimeter(s)

– CIP-006 – Physical Security

– CIP-007 – Systems Security Management

– CIP-008 – Incident Reporting & Response Planning

– CIP-009 – Recovery Plans for Critical Cyber Assets


Proven Security Solutions

•  Physical Protection

•  Network Controls: Admission, Segmentation

•  Strong ID, Authentication and Authorization

•  Aware Person System (Training and Awareness)

•  Intrusion Detection/Prevention

•  Integrity Assurance

•  Application Whitelisting

•  Response and Recovery


You Don’t Need a Perfect Defense

•  If defensive measures can be beaten, does the system ensure the results of the attack are : –  Unprofitable

–  Limited in its ramifications

–  Hard enough to make the “juice” not worth the “squeeze”

–  Difficult to replicate

–  Quickly and easily recoverable

–  Traceable and easy to detect; and

–  Otherwise unappealing

C Why Your Role Is Increasing

l  Increased attacks to business processes l  NERC CIP compliance l  The deployment of smart grid

l  These are increasingly drivers for cost recovery consideration and other contexts in cases that are coming your way very soon

l  Is that reflected in what you’re seeing / hearing?

NA

RU

C Proposal: Roles for

Public Utility Commissions 1.  Ask the right questions when considering cost

recovery of prudent utility expenditures for cyber security.

2.  Assuring that cyber security requirements that utilities are subject to are being met.

§  PUC Staff need to be up-to-date on cyber security requirements and potential threats.

3.  Assuring that the PUC’s computer systems and operations are subject to on-going cyber security reviews and remediation, and that disaster recovery plans are in place and tested.

§  This also included cyber security awareness for agency employees.

4.  Understand and participate in regional and national efforts for protecting critical infrastructure

NA

RU

C l Worth saying twice: someone at the PUC staff needs to be up-to-date on cyber security requirements and potential threats.

l Ask how security is addressed (conceptually) for each component l Don’t accept assurances that all products used were built to be secure, or that IT solutions will work for SCADA systems. Insist that vendors document & independently verify their security controls

l Use “compliance” as a floor, not a ceiling: Ask to see risk assessment documentation

l Ensure security is budgeted for and individuals are assigned responsibility

l Ensure service providers (for example, telcos, meter data processors) are included in risk assessment and provide sufficient information

l Ensure integrated security between business systems and control systems for existing grid and for smart grid

Cybersecurity Investments: What To Ask

NA

RU

C Three examples of State action

l Pennsylvania l Missouri l New York

l PUCs don’t need to become cyber experts or enforces, but if you ask a utility a question they will return with an answer

Resilience Factors

•  Robustness –  The ability to operate or stay standing in the face of

disaster •  Resourcefulness

–  skillfully managing a disaster once it unfolds •  Rapid Recovery

–  The capacity to get things back to normal as quickly as possible after a disaster

•  Learning lessons –  Having the means to absorb the new lessons that can be

drawn from a catastrophe


Resilience Considerations

•  Resilience depends on humans –  Human networks are key –  Ability to work together and individually –  Potential for panic or confusion –  Build necessary connections (relationships) in advance

•  In the event of an electric power sector cyberattack, do you know: –  Your role? If not, whose role it is to act? –  Who to call? What they can /should do?


Protecting The Right Stuff

•  Very little security actuarial data vs. engineering actuarial data

•  Most organizations don’t communicate details of security breaches

•  Most estimates are based on FUD (Fear, Uncertainty and Doubt)

•  Need better/current data on: –  What is being attacked? (most preferred targets)

–  Which attacks were successful?


Product/Service Problem(s)

•  Utilities are married to their products [and vendors] for many years

•  Most products are very expensive to replace or upgrade and challenging to coordinate

•  Product vendors are trying to balance security and profit; guess which one wins…

•  Some vendors are responsive, most are not

•  SCADA Procurement Language can help, but only for new purchases


What Can State Regulators Do?

•  Get educated (even more than today)

•  Strategic communication, in all directions

•  Build new relationships and reshape old

•  Support measures to get actuarial data

•  Support secure procurement measures

•  Support security training/education

•  Support appropriate staffing levels

•  Rethink the rate case approach


What Can State Regulators Do?

•  Ask questions… –  Are you using the SCADA Procurement Language?

–  Are you participating in local, state, regional, national security/disaster exercises?

–  What security training/education/awareness are you providing to your staff and how often?

–  Where do you get your situational awareness data?

–  What cybersecurity technologies do you use?

–  Have you performed a full [exhaustive] inventory of all control systems and all associated communication links?


Education and Training

•  What is happening in Operations, Federal, States?

•  OpSec, Red-Blue, Security Body of Knowledge, security concepts

•  Security practices change rapidly –  Need for training on new tactics and new technology is

perpetual

•  Lack of education leads to a false sense of security –  Otherwise known as knowing just enough to be dangerous


Communication

•  Ratepayers want a secure grid, until they see the bill –  Expect rate shock

–  Rates could triple or more, for some infrastructures

•  “Common Practice” vs. “Best Practice”

•  Early and regular, fact-based communication can minimize negative public reaction

•  Remind ratepayers that smart, informed decisions are being made


Communication

•  Keep the story fresh; lather, rinse, repeat

•  Leverage existing Safety communication vehicles/mechanisms –  Newsletters

–  Mailers, billing notices

–  Public service announcments

–  Sponsored events

•  Partner with utilities, Federal agencies and even Media to convey a unified message


Relationships

•  Get out and talk to your operators

•  Get to know the industry thought leaders

•  What are your peers doing?

•  Situational Awareness –  NESCO, VirtualUSA, Einstein, Fusion centers, Infragard…

•  Take a partnership approach to the rate case (vs. adversarial) as much as possible


Closing Thoughts

•  Cybersecurity is worth taking seriously, but will have to fit into a long list of concerns and priorities

•  There are few response networks for utility sector cybersecurity among State Governments

•  Few of those evaluating cybersecurity investments understand cybersecurity

•  An unskilled operator of any power tool will hurt themselves and those around them –  Training and staffing are imperative

•  A culture shift is the first ingredient for success

•  Soft-skills may matter more than technical skills
