Information Security vs. Cybersecurity: What's the Difference?

Data is the lifeblood of every company and organization. Safeguarding that data is the job of information security and cybersecurity professionals. However, the number of large data breaches since 2000 illustrates the challenges of the job. Companies including Yahoo!, LinkedIn, and Alibaba have experienced breaches that have compromised billions of users’ data.

That’s why the U.S. Bureau of Labor Statistics predicts 35% growth in the number of jobs for information security professionals between 2021 and 2031--significantly higher than the average growth rate for all occupations, which stands at 4%.

Understanding the differences between information security and cybersecurity can help individuals who are interested in this growing career sector decide which direction to pursue. Accelerated training programs such as a cybersecurity bootcamp can provide an introduction to information security vs. cybersecurity and give aspiring professionals a familiarity with the important concepts in each field.

What Is Information Security?

Information security is the process by which an organization protects its data by controlling access to it. Cybersecurity is the subset of information security that focuses on defending an organization from online attacks such as malware or denial-of-service (DoS) attacks.

Information security is responsible for both an organization’s physical security and its online security. Examples of the tools used for information security include:

Employee badges. Badges are the first line of defense to keep unauthorized personnel out of a physical space.
Password protections. Passwords prevent access to a computer network by malicious actors.
Firewalls. These hardware and software tools keep hackers from accessing a server or network.
Biometrics. Sophisticated scanners and other devices help ensure that only authorized personnel can physically access a location or a network computer.
Security awareness training. Information security teams implement ongoing training modules so employees can be aware of common threats such as phishing (emails that purport to come from a trusted source) and social engineering (fostering personal relationships to gain access to data and physical locations).
Disaster recovery planning. The information security team is responsible for developing a disaster recovery plan and making sure that it runs as designed.

The key objectives of information security are confidentiality, integrity, and availability, commonly abbreviated as CIA. The healthcare industry provides a relatable example of how CIA applies to a field with complex data and needs.

Confidentiality

Personal healthcare information must be kept confidential according to the Health Insurance Portability and Accountability Act (HIPAA) under threat of serious penalties. This data, which includes patients’ medical, financial, and personal information such as name, address, and demographics, is high-value data.

Integrity

A hospital or doctor’s office must secure the integrity of its data and protect its accuracy. If a provider’s data is corrupted due to a system failure or because it was maliciously altered by an unauthorized person, it can impact their ability to provide care. Data integrity means ensuring that the data is accurate and usable for people who are authorized to access it.

Availability

Data that is locked away from all users may be safe, but it’s no longer useful. Data has to remain available to authorized personnel. Doctors, nurses, and hospital administrators need to access data to treat patients, send out billing information, and schedule additional care. This concept applies to many industries. For example, an accounting team may need access to an organization’s sensitive financial data, which other teams may not be authorized to see.

What Is Cybersecurity?

Cybersecurity protects data from digital attacks. It secures access to data on computers and networks. Cybersecurity professionals set up virus scans, anti-malware software, and intrusion prevention systems, which monitor for suspicious activity.

The operational areas of cybersecurity include:

Network Security

Preventing unauthorized access to an organization’s computer network is the first line of defense. This may include blacklisting suspicious sites so users don’t inadvertently click on malware. Spam filters catch suspicious emails. Organizations must constantly update their network and keep abreast of security patches. Out-of-date software is one of the most common ways for hackers to breach an organization’s network.

Cloud Security

The popularity of cloud applications and the number of cloud hosting providers means that data is fragmented and accessible from many more access points. Cybersecurity professionals must understand cloud security and how it impacts their strategy to protect their organization.

Penetration Testing

A cybersecurity analyst may be responsible for breaking into their own systems to identify vulnerabilities. They provide a report on their findings and make recommendations to improve the organization’s security profile. Experts say that organizations should run penetration testing exercises once a quarter.

Disaster Recovery

If a breach occurs, the cybersecurity team is responsible for implementing the disaster recovery plan for their organization. In the case of a ransomware attack, an organization must be able to access its most recent backups and be up and running again with minimal downtime. In the case of a DoS (denial-of-service) attack, cybersecurity professionals move into action to circumvent the attack and bring the organization back online, allowing business as usual to resume.

Information Security vs. Cybersecurity: How Are They Different?

The differences between the information security and cybersecurity professions can be summed up as follows:

Information security protects all data, both digital and physical data. Cybersecurity shores up digital defenses, focusing on software and hardware.
Information security deals with both physical and digital threats; cybersecurity deals only with digital threats.
Information security develops policies and procedures; cybersecurity implements them.
Information security develops the disaster recovery plan; cybersecurity implements it.
