In today’s hyper-connected world, where nearly every aspect of our lives is linked to the internet, safeguarding sensitive information is more important than ever. You might be thinking, “I’ve heard of cybersecurity, but what about information security?” These terms, though closely related, are different, and both are critical in the fight against cyber threats. Let’s dive into how information security forms the backbone of cybersecurity, ensuring that your data is always protected.
What Is Information Security?
At its core, information security (InfoSec) is all about protecting data—whether it’s stored on your computer, traveling across a network, or even stored in the cloud. The goal is simple: protect sensitive information from theft, unauthorized access, alteration, or destruction. Think of it as locking your house and putting a security system in place to ensure only authorized people can get in.
The three main principles that define information security are:
- Confidentiality: Ensures that only authorized people can access sensitive data.
- Integrity: Guarantees that the data hasn’t been tampered with.
- Availability: Ensures that authorized users can access data whenever they need it.
These principles are essential, but information security is just one part of a much larger cybersecurity picture.
Cybersecurity: The Larger Defense System
While information security focuses on protecting the data itself, cybersecurity is the umbrella term for everything involved in defending against cyber threats. This includes protecting systems, networks, and devices from attacks like hacking, malware, and ransomware.

Cybersecurity strategies work together to form a layered defense. From network security and application protection to endpoint security and cloud defense, each element plays a role in securing your entire digital ecosystem. One critical aspect of cybersecurity is detection and response—tools like intrusion detection systems (IDS) and security information and event management (SIEM) systems keep an eye out for any suspicious activity and ensure that the system reacts promptly.
Real-Life Example: The 2017 Equifax Data Breach
A perfect example of the importance of both information security and cybersecurity came in 2017 when Equifax, one of the largest credit reporting agencies, was the victim of a massive data breach. Hackers exploited a vulnerability in Equifax’s web application, gaining access to sensitive personal information of approximately 147 million people, including Social Security numbers, birth dates, and addresses. The breach highlighted two major failures:
- Information Security: Equifax failed to properly encrypt sensitive data, making it easier for attackers to access and steal personal details.
- Cybersecurity: The company also failed to patch a known security vulnerability in its system in time. Despite a warning from the U.S. Department of Homeland Security about this vulnerability, Equifax didn’t address it for weeks, allowing attackers to exploit it.
This breach serves as a stark reminder of how intertwined cybersecurity and information security are, and why both are critical in protecting sensitive data.
How Information Security Powers Cybersecurity
Imagine cybersecurity as a fortress and information security as the vault inside it. Even if a cybercriminal breaches the perimeter, strong information security practices will ensure that sensitive data remains safe.
For example, encryption ensures that data remains unreadable to anyone without the decryption key. In addition, technologies like data loss prevention (DLP) monitor and control who can access and share sensitive information, making it harder for attackers to exploit it.
Real-Life Example: WhatsApp and End-to-End Encryption
WhatsApp is a prime example of how information security practices—specifically encryption—keep users’ data safe. WhatsApp employs end-to-end encryption to ensure that only the sender and receiver can read the messages. Not even WhatsApp itself can access the content of your messages.
In 2019, this was especially significant when the company faced a targeted cyberattack using a vulnerability in the app’s video-calling feature. Hackers were attempting to install spyware on users’ devices. Despite the breach, the encrypted nature of the communication meant that even if the spyware infiltrated a user’s phone, the content of their messages remained secure.
Why Information Security is More Critical Than Ever
As cyber threats evolve, so too does the need for robust information security. Cyber attacks are growing in complexity, and a single breach can lead to devastating losses, from intellectual property to personal data. The increasing reliance on cloud computing and the rise of remote work make securing information even more challenging.
Real-Life Example: The Cloudflare Leak
In 2017, a security flaw in Cloudflare’s systems led to a massive data leak. The company, which provides content delivery services, suffered an incident where sensitive data, including login credentials, private messages, and even personal information, were exposed. This was due to a bug in the company’s software that caused data to be unintentionally cached and exposed in web traffic.
The breach was significant because it showed how even large, well-known companies can fall victim to information security vulnerabilities. While Cloudflare’s cybersecurity team responded quickly and fixed the flaw, the incident underlined how crucial it is to secure data at every point in its journey—from the server to the user’s device.
Why Information Security Matters.?
Ultimately, information security is the backbone of any comprehensive cybersecurity strategy. While cybersecurity protects against a wide range of potential threats, information security ensures that your most valuable asset—data—remains protected. As technology continues to evolve and cybercriminals get more sophisticated, securing information through robust security practices is essential for maintaining trust and protecting both personal and organizational data.
