Its time to rethink everything a governance risk compliance primer

It’s Time to Rethink Everything:
A Governance, Risk, and Compliance (GRC) Primer

James Tarala, Enclave Security

Problem Statement
• News agencies are reporting new data breaches
almost on a daily basis
• Resources to protect information are limited
• Senior executives have not engaged to protect data

• What we’re doing to secure enterprises isn’t working
• It’s time to rethink how we protect our data

A Governance, Risk, & Compliance (GRC) Primer © Enclave Security 2011

Proposed Solution - IT GRC
• One proposed solution therefore would be a proactive
program for GRC
• When it comes to IT GRC, there are three primary
components:
– Governance
– Risk
– Compliance


What is GRC (OCEG definition)?
• A system of people, processes, and technology that
enables an organization to:
– Understand and prioritize stakeholder expectations
– Set business objectives that are congruent with values and risks
– Achieve objectives while optimizing risk profile and protecting
value
– Operate within legal, contractual, internal, social, and ethical
boundaries
– Provide relevant, reliable, and timely information to appropriate
stakeholders
– Enable the measurement of the performance and effectiveness of
the system


IT Governance – Defined
• The Institute of Internal Auditors defines IT Governance as the
following:
“Information Technology Governance consists of
leadership, organizational structures, and processes
that ensure the enterprise’s information technology
sustains and supports the organization’s strategies and
objectives.”


Business, Strategy, & Risk
• These three concepts definitively walk hand in hand
• Businesses are run via strategies
• Strategies define & inspire business operations
• Risk appetite & culture helps to influence strategies

• The three are a team, and to understand which controls are
appropriate for an organization, the interaction between
these concepts must be understood


A General Framework
• Business goals lead to…
• Strategy, which leads to…
• Policies, which are defined by…
• Procedures, which are clarified by…
• Standards & Guidelines, which necessitates…
• Risk Management, which causes the evaluation of business
goals
• And so the process repeats


Business Goals
• An organization needs to understand why they exist
• Once a business understands their purpose, they can
determine which tools can assist them to reach their goals
• Technology may be one of those tools

• Technology is simply an enabler for business goals
• Technology should never be implemented simply for the sake
of new technology – there must be a business goal


Business Strategy – Defined
• BNET.com defines business strategy as:

“a long-term approach to implementing a firm's business
plans to achieve its business objectives”

• Also often known as business:
– Objectives / Goals
– Vision / Mission
– Etc, etc…


Defining / Documenting Strategy
• Somehow businesses have to document what their strategy is
• These are documented for clarity, consistency, and to help
educate workforce members
• Different business gurus recommend different methods of
documentation, some options include:
– Mission statements
– Vision statements
– 3 / 5 / 10 year plans
– Strategic roadmaps
– Etc


Influences to Strategy
• There are a number of forces which influence an
organization’s strategy
• These forces define the business & shape their plans

• Some forces include:
– Corporate culture
– The competitive marketplace
– Government / industry regulations
– Individual executive personalities / goals


Policies – Defined
• ISACA defines a policy as:

“A document that records a high-level principle or course of
action which has been decided upon. A policy’s intended
purpose is to influence and guide both present and future
decision making to be in line with the philosophy, objectives
and strategic plans established by the enterprise’s
management teams.”


Policy & Senior Executives
• Policy is the result of documented business strategy
• Senior executives are the ones to set strategy
• Therefore senior executives should be the ones to charter
policy based initiatives

• Senior executives do not have to write the policies, but they
do need to approve of the policies
• Typically the IS Steering Committee is the group with the
responsibility to write & recommend policy documents


Policy Creation
• Someone has to actually write the policies though
• The draft author should be someone who understands the
issue being addressed & relevant business goals
• Do not be afraid to start with policy templates & build off of
other people’s work
• Generally the drafting process is done by a team, delegated by
the IS Steering Committee

• Auditors certainly can engage in the drafting process – it does
not violate the spirit of auditor independence


Necessary Policies in a Library
• One of the first steps in creating or auditing policies is to
generate a list of policies that should be included in the policy
library
• What policies should be documented in the library?

• References to consider are:
– The SANS Policy Project
– Information Security Policies Made Easy (Wood)
– T2P Policy Wiki


Sample Information Security Policies
• Some sample security policies to consider are:
– Acceptable system use policy
– Acceptable encryption policy
– Remote network access policy
– Data access authorization policy
– User authentication policy
– Network monitoring policy
– Incident handling policy
– Business continuity / disaster recovery policy
– Physical security policy


Consensus Audit Guidelines (CAG)
• Known as Consensus Audit Guidelines (CAG) and as the
Twenty Critical Security Controls for Effective Cyber Defense
• Released in 2009 by CSIS and the SANS Institute
• Collaborative effort by over 100 US agencies & private sector
researcher groups
• Purpose is to “establish a prioritized baseline of information
security measures and controls that can be continuously
monitored through automated mechanisms”


IT Governance Frameworks
• There are two major frameworks that are used by auditors to
assess IT governance:

– ISACA’s Control Objectives for Information & Related
Technologies (COBIT)
– IIA’s GTAG 15: Information Security Governance


Using the Frameworks
• These frameworks are meant to be a help for your
organization as you make GRC decisions
• Organizations should not attempt to write their own
• When it comes to governance, pick a framework and use it as
the foundation for your GRC program
• Senior executives and all business owners should be on board
with the decision
• Next, as you go through the next sections, use the framework
you chose as the basis of answering the questions that are
raised


Formal Risk Management Models
• Formal risk management models are meant to be the next
step after an organization follows the steps from the previous
section
• If an organization follows those steps, but wants more from
risk management, then a formal model makes sense
• Organizations need to know why they are doing risk
management & what they hope to achieve from it

• What are the business objectives you hope to achieve?


Formal vs. Ad hoc Models
• Ad hoc models – how organizations will describe nonexistent,
informal, or half hearted risk programs
• Formal models – defined, thoughtful methods of performing
risk management

• Formal models enable businesses to create a plan for
managing risk in light of business strategies

• If an organization is not using a formal model, they likely are
not doing risk management


Choosing the Right Risk Model
• One of the more important risk management decisions an
organization will make is which model to follow

• The model an organization chooses:
– Has to fit the culture of the organization
– Has to be supported by executive management
– Has to be consistent across all business units
– Has to be used comprehensively
– Has to be useable and produce valuable outputs
