Different Types of IT Security


In today’s blog, I will explain to you the different types of IT security. Before hopping into the details, first, let’s explore everything about it then gradually I will describe its different types. 

What Is IT Security? 

It can be defined as the set of different cybersecurity strategies used to control and prevent unauthorized access. 

IT Security meant to control illegal access to an organization’s network, assets, and data. It also helps to block hackers’ to the network. 

Why is IT Security the need of the hour? 

 With time, cyber attackers are becoming more sophisticated and IT security is making us better in dealing with threats. Hackers are launching new attacks to take control of the system.it helps organizations to stay proactive against attacks that cause severe data breaches. 

The cost of this is less expensive than what an enterprise has to bear with a data breach. Therefore, investing in security is crucial today. This acts as a risk management tool and provides a response plan against targeted cyber attacks. To understand the importance of that, let’s take a look at the following stats. 

The virtual private network USA market size is 27.1 billion alone in 2020. Similarly, other security tools like web vulnerability scans, encryption, and wireless network defense tools are also increasingly used by organizations. The stats mentioned above exhibit the sheer potential of that and how it helps companies to fight against cyber threats. 

IT Security vs. Cybersecurity 

Both sound similar, but technically both are different from each other. When we talk about IT security, it refers to the implementation of the systems and measures designed to protect network data. 

Their way is broader than cybersecurity. Cybersecurity on the other hand mainly focuses on the prevention of cyberattacks. 

Common Threats 

There are different forms of threats. The purpose of all threats is to exploit a device to access and disrupt the network. Therefore, it is important to keep the most reliable and updated practices to avoid threats. Some of the most common IT threats are malware, spyware, ransomware, and viruses. 

What are the benefits? 

Every year organizations make heavy investments in IT security. If all the security practices are successfully implemented then enterprises can leverage the IT security to the maximum. 

This controls and prevents potential security breaches that may disrupt an organization. It assures that only relevant users can access your system and information that resides within the system. 

Most importantly, it keeps the confidentiality of the network and the entire data within that network. 

Types of IT Security 

This performs all the possible actions to maintain access control. Meanwhile, it also mitigates the risk of a data breach.  There are different types of IT security among which the most popular are: 

Network Security 

Network security manages the device’s interaction on a network including both hardware and the software. 

Network security aims to secure the underlying network infrastructure from various threats including malfunction, unauthorized access, and other destructions. 

Therefore, network security creates a secure environment in the form of a platform where devices and programs perform functions safely and accordingly. 

Network security is based on configuration and preventive measures like detection system and response protocol to minimize the risk of a network breach. 

End-to-end encryption and two-factor authentication are considered as the most effective methods of network security. 

End-Point Security 

End-Point Security also deals with devices and their interaction. It makes the environment secure at the device level. End-Point security works for different devices that include cell phones, PC, and laptops. It prevents devices from reaching a malicious network that may be a threat to your organization. 

End-Point security software works with tools like encryption, application controls, limited user control, intrusion detection, and data controls. 

With encryption, data remains secure during transmission while application controls prevent malicious downloads from the user’s end. 

When implemented on the company’s server, End-Point Security software helps an organization to check and monitor users’ login across all end-point devices. 

The best examples of End-Point Security are advanced malware protection and device management software. 

Internet Security 

Internet security deals with network security web-based applications and information that is sent and received within browsers. Internet security aims to check incoming internet traffic and filters malicious or unwanted traffic. Internet security can be anything ranging from firewalls, antimalware, spyware etc. 

At its simplest, Internet security prevents targeted attacks on selected browsers, operating systems, applications, and networks. 

Application Security 

Application security is a pro-active security approach. It involves special codes while designing an application. The main objective of the code is to ensure that the application is robust and cannot be exploited by any attacks. 

Application security evaluates the application code to identify vulnerabilities that exist inside the software. Application security is important for developers to monitor, understand, and fix security vulnerabilities. 

Application security is critical because these days, apps are connected to the cloud and run on every network, making devices vulnerable to threats. Application security enables developers to continuously check and update apps to reduce threats and breaches. 

Cloud Security 

Cloud security ensures that the data stored on the cloud is protected from theft, deletion, and leakage. Different methods can be used to maintain cloud security including firewalls, virtual private networks, penetration testing, obfuscation, and more. 


The aspect of IT security is broader than you may think. Their tools prevent the system from intrusion and breaches. If you want to keep your security on the top then select its tools as per your business needs. 

I hope that this article was helpful given you all the necessary insights on that and its types.
