Enhancing Utility Cybersecurity Culture

October 3, 2017

Tim Heidel, Deputy Chief Scientist, NRECA

Utility cybersecurity challenges

• Variety of attacker goals (financial gain, infrastructure damage, etc.)

• Every utility is unique and has different needs and requirements

• Risks can include:

• Malware and viruses (email and thumb drives)

• Insider threats

• Loss of sensitive data and personal info

• Phishing/social engineering/email scams

• Loss of system control or awareness

• Substation or other facility intrusion

Data breach, ransomware recovery costs

• Lost productivity and downtime

• Financial losses associated with a ransom payment or fraud

• Costs to recover data and restore normal business capabilities

• Negative publicity/damage to reputation/ brand

• Legal expenses

• Cost of credit monitoring services for employees and/or members

E. Cody, “Disruption by Design: the Escalating Ransomware Threat,” NRECA TechSurveillance Whitepaper, September 2016

Supply chain risks

• Hardware trojans:

• Modified circuitry (e.g. integrated circuits) designed to provide unauthorized access to data or software on critical systems

• Designed to disable or destroy a system at some future time, or leak confidential information and secret keys

• Software: • Vendors may neglect security and validation of software during rapid

development.

• Poor software configuration

• Malware insertion

• Commercial Off The Shelf (COTS) products that rely on non-vetted

suppliers (foreign or domestic)

• State-of-the-art cybersecurity assessment methodologies and software tools are often designed to be used by large, dedicated IT departments with cybersecurity experts on staff

• Cybersecurity management can be costly and time consuming, particularly for smaller utilities

• NRECA is working to adapt assessment procedures and software tools to best meet the needs and resources of small and medium utilities

Developing comprehensive utility asset inventories

IDE-01 Do we have an inventory of all our computers?

IDE-04 Do we have an inventory of all our corporate mobile devices (e.g. Cell phones, tablets, laptops, etc.)?

IDE-05

Do we have an inventory of all our employee personal mobile devices that may connect to the corporate and/or operational network (e.g. Cell phones, tablets, laptops, etc.)?

Identifying critical data utilities store and use

IDE-12

Bank Account Information: Have we identified all computers, network equipment, and mobile devices that store, process or transmit our member or businesses bank account information?

IDE-13

PII: Have we identified all computers, network equipment, and mobile devices that store, process or transmit our member or business PII?

IDE-14

Credit Card Numbers: Have we identified all computers, network equipment, and mobile devices that store, process or transmit our member or business credit card numbers?

Mitigating sourcing risks (human and technology)

IDE-39 Do we screen candidates for hire by conducting background checks?

IDE-45

Do vendors and third party service providers that have access to our buildings or network conduct background checks on the employees they hire?

Verizon works overtime to understand customer needs

26

• We capture the voice of the customer via Customer Advisory Boards

(CABs) representing a wide variety of industries

• December 2017 User Forum will feature deep-dive discussions with

customers on outcome-based security services

• Years of experience analyzing

customer security data enables

us to continually grow our Threat

Library and our inventory of

industry-specific use cases

• DBIR provides actionable insight

into the situation in the real-

world “security operations

trenches”

Security Built In From The Start

Network Interface layer: authentication using EAP,

helps protect the network operator from liability.

Internet layer: using MPLS, IPsec and LT2P,

helps protect the enterprise from risk.

Application layer: with digital signature, SSL/TLS

encryption and mutual authorization, helps protect

data owners from liability and privacy concerns.

+ Which devices can access your network.

+ What resources and applications those devices can connect to.

Private Network

With the Private Network, you control:

Private Network



• Interconnect multiple providers with no

additional resources

• Create a secure entry point into your cloud

ecosystem

• Control costs

• Create redundancy for cloud resources

• Assign cloud resources as needed

• Interconnect virtual machines configured on

different cloud service provider (CSP)

platforms and/or between different regions of

the same CSP

IoT Security Credentialing: three layers of protection

IoT Security Credential

Protects in three ways:

Trusted authentication: helps keeps

hacker and malicious code out of

your IoT eco-system

Application protection: adds an OTT

layer of security that helps protect the

devices and applications regardless of

provider.

Data security: helps prevent your

data from being changed or view

by untrusted actors.

Be vigilant

Make people your first line

of defense.

Only keep data on a

“need to know” basis.

Patch promptly.

Encrypt sensitive data.

Use two-factor authentication.

Don’t forget physical security.
