Information security policy

What is an information security policy?

An information security (InfoSec) policy is a written set of rules that explains how an organization protects its information and the systems that store, process, or transmit it.

InfoSec policies commonly address the following areas:

Security goals and scope: Data, devices, networks, and services covered.
Ownership, accountability, and applicability: Who approves/maintains the policy, handles exceptions, and who must comply (employees, contractors, vendors).
Data classification and handling: Sensitivity levels and protocols for labeling, storing, and transmitting information by its category.
Required controls and behaviors: Rules on access, data handling, device use, and incident reporting.
Risk and compliance alignment: How expectations tie to business risk and legal or contractual obligations.

How does an InfoSec policy work?

Implementation may differ depending on the organization, but some common methods are: Information Security Policy Operational Framework

Approval and authority: Leadership approval supports cross-departmental enforcement; security teams often draft it.
Roles and responsibilities: A security leader, often a Chief Information Security Officer (CISO), typically owns the policy content and review cycle. System/data owners implement controls in their areas; staff and vendors comply according to their roles and contracts.
From policy to action: Policy states the “what”; standards and procedures define the “how”:
- Policy: High-level rules and expectations.
- Standard: Specific, measurable requirements, such as password length or logging retention.
- Procedure: Step-by-step instructions, such as access requests or incident reporting steps.

Training, enforcement, and review: Training supports a consistent understanding of policy requirements. Enforcement may include access reviews, monitoring, and audits. Reviews occur at regular intervals or after incidents, system changes, or risk shifts.

Where is it used?

InfoSec policies apply wherever sensitive data and connected systems exist, with examples varying by industry. Common areas include:

Corporate information technology (IT) and Software-as-a-Service (SaaS) environments.
Cloud services and hosted infrastructure.
Remote work and bring-your-own-device (BYOD) programs.
Regulated sectors (healthcare, finance, and government).
Vendor onboarding, contract reviews, and third-party risk programs.

Why organizations create information security policies

Organizations create InfoSec policies to define expectations for protecting information and managing risk across systems and teams.

An InfoSec policy typically:

Establishes shared rules for data handling and system access.
Aligns security decisions with business risk and operational priorities.
Defines roles, reporting paths, and responsibilities.
Provides a reference point for audits, contracts, and regulator inquiries.
Promotes consistent security practices across departments and vendors.

FAQ

Who owns and approves the policy?

Senior leadership typically approves the policy for organization-wide authority. A security leader or security team typically maintains it and handles updates/exceptions, while business/system/data owners typically enforce it in their workflows.

How often should it be reviewed?

Many organizations review the policy annually or following any incidents, major system/vendor changes, or shifts in legal or contractual requirements.

What’s the difference between policy, standard, and procedure?

A policy sets the organization’s rules and accountability at a high level. A standard turns those rules into specific, measurable requirements, such as password length. A procedure explains the steps to follow to meet the standard, such as how to report a suspected incident.

How is compliance with the policy enforced?

Compliance can be enforced through training, technical controls, and oversight (access reviews, monitoring, audits, exception tracking), as well as vendor contracts that require security practices and breach notification.
