7 Different Types of Cyber Security: How Each Protects Against Common Threats

In today’s modern world, anyone with a computer, smartphone, or other internet-connected device can be a target for cybercriminals. It’s a scary thought if you dwell on it. Luckily, today’s types of cyber security solutions can help mitigate or stop cyber attacks meant to cause harm to people or businesses. 

In this article, we’ll look at cyber security, why it’s important, the types of cyberattacks, and the seven common types of cyber security. It’s a lot to unpack, so let’s get started. 

What Is Cyber Security?

When we talk about cyber security, we mean any threat or attack intended to access information, halt or disrupt digital workflows, or damage or delete data. Cyber threats can come from various places, including people, criminal organizations, hackers, terrorist groups, and disgruntled employees. Certainly, these attacks on digital data, used to steal a company’s data or gain access to their accounts, have been on the rise, making a cyber security plan crucial. 

Why Is Cyber Security Important?

Cyber security is vital for businesses and people alike. A company must protect its customers and data from cyberattacks, data breaches, and identity theft. There are many ways hackers can attack using online means. And now that so much of our work is ingratiated with technology, cyberattacks are getting much more sophisticated. As a result, businesses need a cyber security plan in place. Not only that, it must be sophisticated enough to keep ahead of today’s advanced crimes. 

Here are the most common cyberattacks:

  • Malware
  • Phishing
  • Ransomware
  • SQL Injection
  • Brute Force

Let’s take a more in-depth look at each one.

Viruses, spyware, ransomware, and any malicious program on your system all count as malware.

Malware can infect computers and other devices. The malicious software can steal information, launch attacks on systems, and hijack devices after gaining unauthorized access. Malware can come in the form of viruses, worms, spyware, and ransomware. 


Phishing involves sending emails or other messages intended solely to get personal information, such as credit card numbers, passwords, and other sensitive data. These suspicious messages may look like they’re from a reputable company, so the unsuspecting recipient will open them and follow any instructions detailed inside. The instructions may entice the viewer to click malicious links or give private information. A phishing attack aims to steal data or install malware on someone’s computer. 


Ransomware is a type of malware. This type of cyberattack encrypts systems and files, which can lead to a loss of data or even a complete shutdown of a machine. The ransomware will continue to block access until someone pays the attackers money. 

SQL Injection

An SQL, or Structured Query Language, code injection attack can destroy a database. This type of cyberattack uses malicious code on a server that uses SWL. Once it’s infected, the server will release sensitive data. SQL injection attacks are one of the most common types of cyberattacks, and attackers can perform it as quickly as entering the infected code into a vulnerable web page text box. 

Brute Force

Brute force attacks are one of the oldest cyber security issues around. Hackers or bots try to break into computers and networks. They do this by repeatedly trying to guess the login credentials for a site. Once they’re in, hackers can add malware to access sensitive information. 

7 Different Types of Cyber Security

Now that we understand why it’s important to protect yourself and your business, let’s go over the seven common types of cyber security you can use to protect your sensitive information. 

#1. Network Security

Use a firewall to keep your network secure from outside threats.

Most cyber security attacks will occur over the network. Network security is the process of using a set of technologies within a network to keep your own and your company’s data safe. Typically, network security will identify issues and block them using a few different solutions. These solutions include a next-gen firewall, data loss prevention, and access management. 

#2. Information and Cloud Security

Information security, or InfoSec, is a process that uses cyber security tools to protect critical business information from attackers who want to disrupt operations or access or destroy sensitive data. 

Part of information security is cloud security. The cloud has made us rethink cyber security, and now more businesses are adopting cloud security solutions. Cloud security focuses on solutions to protect against network and cloud-connected device attacks. These solutions include controls, policies, and services to protect an enterprise’s cloud applications, data, and infrastructure. 

Many cloud users find that cloud providers can’t provide the best cyber security, so many people rely on third-party cloud security solutions. 

#3. Mobile Security

These days, many people use mobile devices for work. That means these phones and tablets contain highly sensitive data. If left unsecured, mobile devices can become riddled with malicious attacks through apps, messages, and phishing attacks. Businesses and people can protect mobile devices with mobile security, which includes safeguarding against jailbreaking and rooting. In addition, an MDM, or mobile device management plan, ensures that only allowed mobile devices have access to corporate information. 

#4. IoT Security

IoT, or the Internet of Things, describes a network of devices, or “things,” that are embedded with software and sensors. The software and sensors connect devices and exchange data between these systems over the internet. However, while using the internet, IoT devices can expose businesses to cyber security threats, especially if these devices are left vulnerable.

IoT threats are not just for businesses; hackers can also attack smart home devices such as smart TVs and baby monitors. 

Using IoT security solutions protects devices by employing fixes, such as software updates, credential security, encryption, and device authentication. 

#5. Application Security

Application security describes the process of developing and adding cyber security features within any applications connected to the internet. Some common threats to applications include unauthorized access and modifications. Application security prevents attackers and malicious interactions with continuous learning. Continuous learning allows apps to remain protected as new content becomes available. 

#6. Endpoint Security or End User Security 

Endpoint or end-user security refers to the first line of defense when dealing with cyberattacks. People use devices such as computers to identify and stop most attacks. 

Education and knowledge of cyberattacks and cyber security are the best ways to help you and your business avoid hacking and cyber threats. Most companies offer or require cyber security education to prevent attacks and to educate their employees about today’s worst dangers. 

#7. Zero Trust Security

Zero Trust refers to a corporate need to protect valuable assets without using outdated, traditional perimeter-focused security. Instead, zero trust is more in the weeds and protects individual resources by monitoring and enforcing role-based access. This cyber security framework requires all users to be authorized and authenticated before granting access to data and applications. In addition, users will need to be continuously validated. 

Cyber Security: Protecting Yourself Against Common Threats

Cyber threats are part of our life now. Unfortunately, threats are coming at us through the devices that we use daily. From convincing phishing attacks to brute force attacks, if your device is online, it’s vulnerable to cyber threats. The good news? There are many ways for businesses and individuals to protect themselves from scammers and hackers. These days, we must take cyber security measures at every level to help protect sensitive data, such as names, birthdates, social security numbers, credit card numbers, and other personal information. 

Some ways you can protect data are to teach yourself and your employees or team about common cyberattacks and how to prevent them. Update your software when available. And be sure to stay current on the most recent cyber security solutions available. Finally, be sure you have security systems and a recovery plan in place should the unthinkable happen. The damaging effects of cybercriminals can be costly. 

As long as the internet exists, hackers will always be around. But we don’t have to give them the upper hand. Instead, utilize every cyber security measure to help protect against every common threat known today.
