6 Common Types of Cyber Security You Should Know

What Is Cyber Security & Why Does It Matter Today?

In today’s hyper-connected world, every digital action—from sending an email to using a mobile app—exposes you to potential cyber threats. Cyber security refers to the practice of protecting computers, networks, software, and data from unauthorized access, theft, or damage. With global cybercrime costs projected to hit $10.5 trillion annually by 2025 (Cybersecurity Ventures), understanding the types of cyber security is more important than ever.

As businesses move operations to the cloud, and individuals rely more on digital devices, threats like ransomware, phishing, and data breaches have become increasingly common. Whether you're a student, business owner, or IT professional, knowing the common types of cyber security can help you stay one step ahead of attackers and protect your sensitive data in a constantly evolving threat landscape.

In this blog, you'll explore six key categories of cyber security, learn what makes each one important, and discover real-world examples of how they work.

The 6 most common types of cyber security include:

1. Network Security – Protects internal systems and data from unauthorized access

2. Cloud Security – Secures data and apps stored online

3. Application Security – Keeps software and apps safe from code-based threats

4. Endpoint Security – Safeguards laptops, mobiles, and other user devices

5. Internet Security – Blocks harmful content and phishing on the web

6. Information Security – Focuses on keeping data private, accurate, and accessible

What Are the Different Types of Cyber Security?

1. Network Security

Network security is the most basic and important type of cyber security. It helps protect your internal computer network from hackers, viruses, or any unwanted access.

Every time you connect to the internet—whether at home, school, or work—your device becomes a part of a network. If this network is not protected, attackers can steal your data, install harmful software (malware), or stop your systems from working using attacks like DDoS (Distributed Denial of Service).

What it includes:

• Firewalls that block unknown traffic

• Antivirus software that scans for threats

• Network monitoring tools that check for suspicious activity

For example, companies often use tools like Cisco Firepower or Fortinet to keep their networks safe. Even small businesses need network security to protect emails, files, and payment systems from being hacked.

Keeping your network secure is the first step to protecting everything connected to it.

2. Information Security

Information security, also called infosec, is all about protecting your data—whether it's stored on your phone, computer, or cloud. This data could be anything from passwords and photos to business documents and customer records.

Unlike other types of cyber security that protect systems or networks, information security focuses only on the confidentiality, integrity, and availability of data. These three parts are known as the CIA Triad.

How it works:

• Confidentiality: Keeps data private so only the right people can see it

• Integrity: Makes sure no one changes your data without permission

• Availability: Ensures your data is always ready when you need it

To protect your information, tools like data encryption, access control, and backup systems are used. For example, banks use encryption to keep customer data safe, and companies use strict passwords and user roles so only certain employees can access sensitive files.

Out of all the types of cyber security, information security plays a major role in building trust—whether you're running a business or just storing personal data online.

3. Endpoint Security

Endpoint security protects the devices you use every day—like your laptop, mobile phone, or tablet. These devices are called endpoints because they are at the “end” of a network, where users connect to the internet.

Every time you open an email, browse a website, or download a file, your device can be exposed to threats like viruses, spyware, or ransomware. If even one device gets attacked, the whole network can be at risk—especially in schools, offices, or remote work setups.

What endpoint security does:

• Stops malware before it harms your device

• Scans USBs and downloads for hidden threats

• Allows tracking and locking of lost or stolen devices

Companies use tools like CrowdStrike, McAfee, or Bitdefender to keep employee devices secure. Even students and freelancers can benefit by using antivirus apps that protect their phones and laptops.

In this digital age, endpoint security is one of the most necessary types of cyber security to keep personal and professional data safe.

4. Cloud Security

Cloud security is a type of cyber security that protects your data stored on the internet. Today, most people and businesses use cloud services like Google Drive, Dropbox, or Amazon Web Services (AWS) to save files and run apps. While these tools are helpful, they can also be risky if not protected properly.

Cloud data is not stored on your personal device. It’s saved on powerful servers in different locations. If a hacker breaks into these servers, they can access private photos, passwords, business data, or even financial records.

How cloud security helps:

• Blocks unauthorized access using strong passwords and two-step logins

• Monitors cloud systems for unusual behavior

• Keeps data safe through encryption (scrambling information so others can't read it)

Companies use tools like Microsoft Defender for Cloud or Palo Alto Prisma Cloud to keep their cloud data safe from cyber attacks. If you're storing anything online—photos, documents, or even school projects—cloud security makes sure no one else can get in.

5. Application Security

Application security is the type of cyber security that protects apps from being hacked or misused. Apps are not just on your phone—they're everywhere, from websites and banking systems to shopping platforms and online games.

Apps often deal with personal or sensitive data like your name, address, bank details, or passwords. If these apps have coding mistakes or weak spots, hackers can break in and steal your information.

What application security does:

• Finds and fixes bugs before launching the app

• Tests the app regularly to check for new risks

• Uses secure coding practices to stop attacks like SQL injection or cross-site scripting (XSS)

For example, if someone hacks into a banking app using a code error, they can steal user money or leak financial records. That’s why companies like Google and PayPal invest a lot in application security tools like AppScan, Acunetix, and Veracode.

Keeping apps secure means you can use them without worrying about your data getting into the wrong hands.

6.  Internet Security

Internet security focuses on keeping you safe while you use the internet. Every time you browse websites, send emails, or use social media, you are exposed to online threats like phishing scams, fake websites, and malicious ads.

Without proper protection, attackers can trick you into clicking harmful links, stealing your login info or even installing viruses on your device.

How internet security helps:

• Blocks dangerous websites and pop-ups

• Protects your web browser with extensions and filters

• Keeps your data safe when you shop or bank online

Examples of tools used for internet security include browser extensions like HTTPS Everywhere, ad-blockers, and VPNs (Virtual Private Networks). These tools hide your location and make sure your connection stays private.

Among all the types of cyber security, internet security is essential for day-to-day safety, especially for students, professionals, and anyone spending time online.
