As a CISSP candidate, you'll encounter security governance as a fundamental concept that shapes how organizations protect their assets while achieving business objectives. While technical controls are important, it's governance that determines how effectively an organization manages its security program.

Understanding security governance isn't just about policies and procedures—it's about grasping how security enables and protects your organization's core business goals. In this guide, we'll explore the essential principles of security governance, from organizational value enhancement to the practical implementation of security oversight.

Let's examine how effective security governance can transform security from a reactive function into a strategic business enabler.

Understanding Security Governance

At its most basic level, governance means overseeing and directing something. In an organizational context, it's about properly directing activities to achieve goals and objectives that increase value. Think of it like elected officials who govern to enhance their jurisdiction's value by providing better services and meeting constituents' needs. Organizations operate similarly, with the Board of Directors, CEO, and senior management working to increase the organization's prosperity, sustainability, and viability.

Corporate governance encompasses various activities to increase organizational value - from creating new processes and products to establishing third-party relationships and meeting compliance requirements. Organizations implement these through corporate policies rather than laws, allowing stakeholders to thrive.

Security governance takes this further by including all security-related activities, initiatives, and programs that support these corporate governance objectives. However, this alignment only works in a top-down structure, where those accountable for corporate governance drive security needs. This ensures security truly adds value and helps achieve organizational goals.

mportantly, security should act as a proactive enabler rather than just a reactive function. This requires strong support from senior management—without their conviction about security's importance, the function may struggle. In such cases, organizations might need to educate leadership through internal champions or external consultants about security's value.

Aligning Security Governance with Corporate Governance

For security governance to truly support an organization's objectives, it must be properly aligned with corporate governance. This alignment requires drawing on expertise from across the organization, including:

Senior and upper management
Human Resources
Legal
IT
Other key functional areas

The most effective approach to establishing and maintaining this alignment is through an organizational governance committee. This committee plays a crucial role by:

Establishing and promoting a top-down governance structure
Setting the organizational tone
Meeting regularly to review progress
Including security goals and objectives in organizational planning

Scoping and Tailoring: Key Alignment Processes

Two important processes help ensure security controls align properly with organizational goals:

Scoping

This process examines potential control elements to determine which ones are relevant to the organization. For example, from a legal perspective, scoping identifies which security controls are necessary to comply with applicable laws and regulations.

Tailoring

Once controls are determined to be in scope, tailoring refines and enhances them to be:

Most effective for the organization
Aligned with goals and objectives
Cost-effective relative to what they protect
Valuable to the organization

Understanding Accountability vs Responsibility

One of the most crucial aspects of security governance is understanding the distinction between accountability and responsibility. These two terms are often used interchangeably, but they represent fundamentally different concepts in security governance.

Here are the key differences:

Accountability	Responsibility
Where the buck stops	The doer
Ultimate ownership and liability	In charge of a task or process
Only one person or group can be accountable	Multiple people can be responsible
Sets rules and policies	Develops plans and implements controls

When these processes work together effectively, security governance becomes completely aligned with corporate governance, allowing organizations to achieve their objectives in a cost-effective manner that adds value.

Remember, success depends heavily on top-level support. Without backing from the Board of Directors and senior management, security risks becoming a reactive nuisance rather than the proactive enabler it should be. When leadership understands and supports robust security aligned with organizational strategy, goals, mission, and objectives, the security function becomes a valuable organizational asset.

Organizational Roles and Responsibilities

In security governance, various roles carry different levels of accountability and responsibility. Understanding these distinctions is crucial for effective security implementation.

Key organizational roles include:

Owners / Controllers/ Functional Leaders / Senior Management	Accountable for: Ensuring that appropriate security controls, consistent with the organization’s security policy, are implemented to protect the organization’s assets Determining appropriate sensitivity or classification levels Determining access privileges
Information Systems Security Professionals / IT Security Officer	Responsible for: Design, implementation, management, and review of the organization’s security policies, standards, baselines, procedures, and guidelines
Information Technology (IT) Officer	Responsible for: Developing and implementing technology solutions Working closely with IS and IT Security Professionals and Officers to evaluate security strategies Working closely with Business Continuity Management (BCM) team to ensure continuity of operations should disruption occur
IT Function	Responsible for: Implementing and adhering to security policies
Operator / Administrator	Responsible for: Managing, troubleshooting, and applying hardware and software patches to systems as necessary Managing user permissions, per the owner’s specifications Administering and managing specific applications and services
Network Administrator	Responsible for: Maintaining computer networks and resolving issues with them Installing and configuring networking equipment and systems and resolving problems
Information Systems Auditors	Responsible for: Providing management with independent assurance that the security objectives are appropriate Determining whether the security policy, standards, baselines, procedures, and guidelines are appropriate and effective to comply with the organization’s security objectives Determining whether the objectives have been met
Users	Responsible for: Adherence to security policies Preserving the availability, integrity, and confidentiality of assets when accessing and using them

It's important to note that while responsibilities may overlap or be shared among different roles, accountability typically remains with asset owners and senior management. This structure ensures clear lines of authority while allowing for collaborative security implementation.

Who is Responsible for Security?

The simple answer? Everyone.

Everyone has some degree of responsibility for security in their role; for example, the janitor of a locked building must make sure they're not taking confidential papers off someone's desk and that they're disposing of confidential recycling properly. However, asset owners are accountable for telling people what their responsibilities are.

Asset owners are in the best position to know the value of the assets they control, and they can best determine how much security is needed to protect those assets. They also need to communicate what should be protected, who should protect it, and how to do so. Security professionals provide advice, but it's not up to them to secure anything. Security is ultimately everyone's responsibility.

Due Care versus Due Diligence

In security governance, understanding the distinction between due care and due diligence is crucial:

Due Care	Due Diligence
Accountable protection of assets based on the goals and objectives of the organization. This definition aligns what security should be doing with what the organization should be doing. It aligns accountable protection of assets based on the goals and objectives of the organization. This is what due care means from a security perspective.	Ability to prove due care to stakeholders—upper management, regulators, customers, shareholders, etc. Due diligence is what is done to prove due care on a regular basis to organization stakeholders

To illustrate this concept, consider penetration testing: Due care would be the owner of a system requesting that a penetration test be performed and then authorizing the remediation of the vulnerabilities identified by the penetration test. Due diligence would then be providing proof that the vulnerabilities were addressed in a cost-effective and efficient way to management and other relevant stakeholders.
