Cybersecurity vs Information Security: What Is the Difference?

Cybersecurity and information security are often used interchangeably, but they are not exactly the same thing.

Both focus on protecting valuable information and reducing security risks, but their scope and areas of focus can differ.

If you've ever wondered "What is the difference between cybersecurity and information security?", you're not alone.

The terms are closely related because both involve protecting information from unauthorised access, misuse, alteration, loss or destruction. However, cybersecurity generally focuses more specifically on protecting digital systems, networks, devices, applications and digital data, while information security has a broader focus on protecting information regardless of whether it is stored digitally, physically or in another form.

Understanding the difference can be useful if you're a student, professional, business owner, IT specialist or someone considering a career in cybersecurity.

In this guide, we'll explain cybersecurity vs information security, what each field covers, how they overlap and how to decide which area may be right for you.

What Is Cybersecurity?

Cybersecurity is the practice of protecting digital systems, networks, devices, applications and data from cyber threats.

These threats can include:

Phishing
Malware
Ransomware
Data breaches
Credential attacks
Social engineering
Vulnerability exploitation
Unauthorised access
Denial-of-service attacks

Cybersecurity is primarily concerned with the security of the digital environment.

For example, cybersecurity can help protect:

Company networks
Cloud systems
Websites
Mobile devices
Computers
Business applications
Digital accounts
Online databases

Cybersecurity professionals may work on preventing attacks, detecting suspicious activity, investigating incidents and helping organisations recover from security incidents.

What Is Information Security?

Information security, often called InfoSec, is the practice of protecting information from unauthorised access, use, disclosure, alteration, disruption or destruction.

The important distinction is that information security isn't limited to digital information.

Information can exist in many forms.

For example:

Digital files
Emails
Printed documents
Contracts
Employee records
Customer information
Financial documents
Physical storage devices
Verbal or confidential information

Information security therefore takes a broader view of how information is protected throughout its lifecycle.

It considers questions such as:

Who should have access to this information?

Where is it stored?

How should it be handled?

How long should it be retained?

What happens when it is no longer needed?

Cybersecurity vs Information Security: The Main Difference

The simplest way to understand the difference is:

Cybersecurity focuses primarily on protecting digital environments from cyber threats, while information security focuses on protecting information in all forms.

Think of it this way:

Information Security

Protects information in digital and physical forms

Cybersecurity

⬇

Focuses primarily on protecting digital systems, networks, devices and data

Cybersecurity can therefore be considered an important part of the wider information security landscape.

The boundaries can overlap, and organizations may define roles differently.

What Do Cybersecurity and Information Security Have in Common?

Although they are different disciplines, cybersecurity and information security share many goals.

Both aim to protect:

Confidentiality

Information should only be available to authorized people.

Integrity

Information should remain accurate and protected from unauthorized changes.

Availability

Authorized users should be able to access information when needed.

These three principles are commonly known as the CIA triad and form a foundation for many information security and cybersecurity practices.

Cybersecurity vs Information Security: An Example

Imagine a company has confidential customer information.

The information is stored in a cloud database but some records are also printed and kept in a physical office.

Cybersecurity might focus on:

Securing the cloud environment
Protecting user accounts
Monitoring network activity
Detecting malware
Preventing unauthorised digital access
Securing applications
Managing vulnerabilities

Information security might consider:

Who is authorised to access the customer information
How the digital records are protected
How printed documents are stored
How information is shared
How long records should be retained
How information should be securely destroyed
What policies employees must follow

This example shows why information security has a broader scope.

Is Cybersecurity Part of Information Security?

In many organisations and professional contexts, cybersecurity is considered a component or specialised area within the broader information security discipline.

However, terminology varies between organisations, industries and job roles.

Some companies may use "cybersecurity" and "information security" almost interchangeably.

Others may have separate teams with different responsibilities.

For example:

Information Security

→ Governance → Risk Management → Policies → Data Protection → Access Management → Security Awareness

Cybersecurity

→ Network Security → Threat Detection → Incident Response → Endpoint Security → Application Security → Cloud Security

The exact structure depends on the organisation.

What Does an Information Security Professional Do?

An information security professional may be responsible for protecting information across its entire lifecycle.

Responsibilities can include:

Developing security policies
Conducting risk assessments
Managing access controls
Supporting compliance
Protecting sensitive information
Developing security awareness programmes
Managing information security risks
Reviewing third-party risks
Supporting incident management

Information security roles can therefore involve both technical and non-technical responsibilities.

What Does a Cybersecurity Professional Do?

Cybersecurity professionals often focus on defending digital environments against cyber threats.

Depending on the role, responsibilities may include:

Monitoring security alerts
Investigating suspicious activity
Conducting vulnerability assessments
Responding to incidents
Securing networks
Protecting endpoints
Testing applications

An organisation may have excellent technical security but still face risks from:

Poor access policies
Weak employee awareness
Uncontrolled physical documents
Excessive user permissions
Poor data retention practices
Third-party risks
Inadequate security procedures

Cybersecurity and information security should therefore work together.

Technology protects digital environments.

Information security protects information across its lifecycle.

Together, they support a stronger security strategy.

Cybersecurity vs Information Security in the Workplace

Consider a company employee who receives a confidential customer document.

Information security asks:

How should this information be handled?

Cybersecurity asks:

How do we protect the digital systems through which this information is accessed, stored or transmitted?

Both questions matter.

This is why modern organisations increasingly need professionals who understand the relationship between technology, information and business risk.

Common Misconceptions About Cybersecurity and Information Security
