What is information security?

Cover image for a blog on "what is information security?”

Information security (InfoSec) is a set of methods and processes that protect your company’s information from unauthorized use, access, modification, misuse, disruption, or destruction. Think about all the content your company needs and produces, from budget spreadsheets to employee contracts. Now, consider what would happen if some of that content fell into the wrong hands.

Competitors could get an edge on you, malicious actors could access private customer data, and your company’s financials could be put at risk. InfoSec protects your information by enforcing comprehensive protocols against security threats.

Information security definition

To help you understand how these measures benefit your business, let’s explain information security, its principles, categories, and certifications.

Information security vs. cybersecurity

You might hear people use cybersecurity and InfoSec interchangeably, but the two are not the same. One way to describe the difference between information security and cybersecurity is that InfoSec is a component of cybersecurity. Cybersecurity refers to a broader methodology of protecting information technology assets, not just content or information, from third-party attacks. Let’s take a closer look at the basics of each.

Cybersecurity basics

Cybersecurity is considerably broader than information security. It refers to methodologies and processes an organization might put into place to protect programs, servers, and networks from unauthorized access, misuse, or other types of threats. Cybersecurity may also be called information technology (IT) security. InfoSec is primarily concerned with protecting data and content, whereas IT security aims to protect devices and networks as well.

Several categories of cybersecurity exist, including:

  • Application security: Protects devices and software programs from threats — examples include designing software programs with security features such as file encryption and issuing patches to repair vulnerabilities as they appear
  • Information security: Safeguards information, whether it’s electronic, like data stored or transmitted through the cloud, or physical, like printed files and contracts
  • Network security: Keeps intruders — in the form of malware or attackers who are specifically targeting the network — from gaining access to a company’s computer network
  • Operational security: Includes assigning file and folder permissions and passwords to grant access to certain content types or the computer network itself
  • Disaster recovery: A cybersecurity component that lays out what to do if an organization experiences an attack, has its business disrupted, or loses access to data

Examples of InfoSec threats that cybersecurity measures can protect against include:

  • Phishing scams: When a seemingly legitimate email or message tries to convince people to reveal personal information
  • Malware: Viruses, Trojans, or other computer programs that damage a device or give unauthorized access to specific computer programs or data
  • Ransomware: A cyber criminal who successfully installs ransomware on a device can lock the device and prevent the user from accessing files or programs until the device owner pays a ransom — and paying the ransom doesn’t mean the malicious software goes away, in many cases

Information security basics

The basic components of information security involve protecting data from unauthorized use or access and ensuring information remains compliant with regulations, such as the European Union’s General Data Protection Regulation (GDPR).

The GDPR is one of the strictest information security and privacy regulations in the world. It’s meant to protect citizens of the EU, but any organization worldwide needs to adhere to the regulation if it collects data from EU citizens.

InfoSec principles

Information security is all about maintaining three basic principles: confidentiality, availability, and integrity. The goal of a strong security policy is to achieve at least one of them. Together, the principles and fundamentals of information security make up the “CIA” triad. Let’s take a closer look at each of the three.

The three InfoSec principles are confidentiality, availability, and integrity

1. Confidentiality

One of the first things that may come to mind when thinking about protecting your company’s content is how to keep the data and information it contains confidential. Whether you’re managing employee contracts or customer information, you need to ensure it’s shielded from unauthorized users or views.

The goal of the confidentiality branch of the CIA triad is to keep data private. This means only those who have the appropriate permissions can view specific forms of content.

Several tools are available to ensure a company can keep its data confidential. Those tools include:

  • Password protection: Strong, difficult-to-guess passwords can ensure that only those with permission to view certain types of data get access to it
  • Encrypted document sharing: Encryption protects documents sent from one location to another, such as over email or via the cloud, with the message and meaning hidden in a stream of seemingly meaningless words and number phrases that require a key to decipher
  • Multi-factor authentication (MFA): This measure adds another layer of identification and verification to the sign-on process by asking a user to verify their identity by supplying a second piece of information instead of just a username and password — for example, a four-digit code sent via text message or the answer to a secret question
  • Penetration testing: By imitating the tactics attackers would use when trying to access confidential data, a penetration test lets a company see where it can improve the privacy of its content

2. Integrity

Integrity refers to the condition of the data or content. It’s critical that unauthorized users not be able to modify your company’s content. A malicious actor shouldn’t be able to adjust contracts to increase or reduce the salaries of employees.

It’s also vital that the integrity of your company’s data be protected from individuals within your organization who might not have the best intentions. A jealous co-worker shouldn’t be able to access a colleague’s personal file and change their hours reported or add write-ups or fabricated disciplinary actions to their history.

The information security technologies you’d use to ensure the confidentiality of your content, such as encryption and password protection, also help ensure its integrity. There are measures beyond this that you can take to reverse information security threats. If an individual gains unauthorized access to a spreadsheet and changes the information, data backup and recovery features let you restore previous versions of the content to ensure integrity.

3. Availability

The availability principle ensures that eligible users and individuals can access your content. Availability means that people who need to download or open a piece of content can do so when needed. The principle also ensures that access to a particular piece of content is quick and immediate. This prevents authorized users from being left waiting to open a file or having to go through a lengthy process to access the content they need.

Types of information security

Types of information security include application security, incident response, cryptography, cloud security, and vulnerability management

Information security covers various strategies and processes to safeguard sensitive data from unauthorized access, disclosure, and disruption. Here are some types to include in your information security framework.

Application security

Application security aims to protect software and hardware. It often focuses on preventing code or data from getting stolen from inside the app, software platform, or hardware. An example of this type of information security might be a router that masks a computer’s IP address or a software program that requires user authentication and authorization.

Another example of application security is logging: taking note of who has accessed which piece of content and when.

Incident response

While some types of InfoSec focus on preventing data breaches or leaks, incident response focuses on understanding what happened and making a plan for prevention in the future. A key part of incident response is minimizing damage and reducing the cost to the organization. Incident response can also help an organization discover who was behind the attack and press charges or present evidence to law enforcement.

Cryptography

You want to protect your company’s data while it’s at rest and when it’s in transit — think of data in a folder and data you email to another user. Encryption protects the integrity and confidentiality of your content’s data.

Cryptography is the process of encrypting content. If an unauthorized user accesses an encrypted file and doesn’t have the right decryption key, the content will look meaningless to them. Another component of cryptography is a digital signature, which verifies the content’s source and confirms that it is what it claims to be.

Cloud security

Many organizations use a cloud storage platform to manage their data, allowing them to access their content from any internet-connected device. Cloud information security protects the integrity and confidentiality of the content stored on it, ensuring that authorized users have ready access to their data.

Vulnerability management

According to ISMS.online’s State of Information Security Report 2024, 79% of businesses were impacted by an information security incident caused by a third party vendor or supply chain partner — an increase of over 20% from last year. Another information security example involves managing and minimizing potential vulnerabilities.

These vulnerabilities may include misconfigured access permissions, software updates that might introduce a new weak spot or out-of-date applications that could potentially lead to a breach or break-in.

Information security policy

How do you ensure you’re covering all the InfoSec types and principles? One way to reinforce your company’s information security is to create a policy that outlines the process and procedures you’ll use to keep your content secure.

Your InfoSec policy should be a living document updated regularly as regulations change, technology evolves, and threats develop.

A basic information security policy includes the following elements.

Elements to include in an information security policy

Purpose and objectives

The policy should describe its purpose, such as protecting your customers or maintaining your company’s reputation. It should also outline objectives or goals, which should be in line with the CIA triad’s principles. For example, the policy’s objectives can be to preserve the confidentiality of your data, protect its integrity, and ensure access to all authorized users.

Audience identification

Identify who the policy is and is not meant for. The intended audience might be all employees who access your document management system. Excluded audience members might be independent contractors who don’t have access to the system or employees who work in a department that has a separate policy.

Acceptable use policy

The acceptable use policy outlines how your employees can use company content. It should explain where and when they can download files and what they must do to protect those files’ confidentiality. The acceptable use policy can also include a password policy that describes how to create strong passwords or the type of passwords employees need to set to protect your company’s content.

Data support plan

The policy needs to include a plan for data support and operations so anyone with access can always get the data or content they need. The plan can describe how data is transferred, what types of protection are in place to secure the data, such as encryption, and what practices your company uses to back up files online or restore data when necessary.

Data classification

Your business will likely have different content types, from documents that the public can view to top-secret company policies and procedures. A data classification system should be part of your InfoSec policy to allow you to categorize data, determining who can access it and how they can gain access.

Roles and responsibilities definition

The security policy should outline who is responsible for what when it comes to your content. That includes determining which employees are responsible for incident response and who is responsible for ensuring data is protected and kept confidential when needed.

Information security measures

InfoSec measures are the processes and procedures your company uses to ensure information security and data protection. They can take multiple forms, such as:

  • Access measures: Allow you to control physical access to your data by restricting who can enter certain areas of your building and also include controls on who can access content in the cloud
  • Procedural measures: Include educating your employees on best security practices, such as how to set strong passwords and how to put an incident response plan into place
  • Technical measures: Include passwords, encryption, firewalls, and other software or hardware applications that protect your content
  • Compliance measures: Might not be created by your organization and are more likely regulations and rules you need to follow, such as GDPR or ISO 27001

The measures you put in place protect your information in three ways.

  1. They might be designed to prevent a data breach. According to IBM, the global average cost of this type of incident in 2024 was $4.88M — a 10% increase over 2023. Preventative measures include passwords, encryption, and physical barriers to content in print form.
  2. The measures might also be detective, meaning they spot a breach or hack while it’s in process and alert the appropriate personnel.
  3. Your security measures might also be corrective, meaning you put them into practice after a breach occurs. An incident report plan is an example of corrective action, as it gives you the chance to reflect on what happened and make a plan to prevent a recurrence.

Information security certifications

There are several roles in InfoSec, and information security certifications help professionals advance in their careers by validating their expertise in the area. These credentials validate an individual’s or organization’s knowledge, skills, and adherence to best practices in securing systems, data, and networks.

An example is the chief information security officer (CISO), who is typically responsible for overseeing all aspects of the InfoSec program. CISO can be its own position, or the responsibilities of the role can be lumped into the role of a chief security officer or vice president of security.

The path a person takes to become a CISO, VP of security, or CSO can vary. Several certification programs exist to train people and prepare them for roles in InfoSec. What your company’s certification program might look for when hiring depends on the functions you envision for your InfoSec team and the type of vendors you work with.

These are examples of InfoSec certifications.
