This data often includes sensitive information that, if accessed without permission, can have serious consequences. Cybersecurity focuses on protecting this information and the systems used to process and store it. 

With the increasing volume and complexity of cyber attacks, organizations must prioritize safeguarding sensitive data, especially those responsible for national security, healthcare, or financial records. This is when the need of cyber security is paramount. Cyber-attacks threat surpasses traditional forms of terrorism, making robust cybersecurity measures essential in preserving data integrity and trust. Now that you know why is cyber security important, let’s begin exploring different types of cybersecurity.

The Different Types of Cybersecurity

Cybersecurity is a broad field covering several disciplines. It can be divided into seven main pillars:

1. Network Security:- A network security solution identifies and blocks attacks that occur over the network. To enforce safe web use policies, these solutions contain data and access controls, including Data Loss Prevention (DLP), Identity Access Management (IAM), Network Access Control (NAC), and Next-Generation Firewall (NGFW).

2. Cloud Security:- It is becoming increasingly important for organizations to secure their cloud computing systems as they adopt cloud computing. A cloud security strategy includes cyber security solutions, controls, policies, and services that help to protect an organization’s entire cloud deployment (applications, data, infrastructure, etc.) against attack.

3. Endpoint Security:- Data should be micro-segmented whenever possible according to the zero-trust security model. Endpoint security can protect mobile workforces.

4. Mobile Security:- Businesses are exposed to malicious apps, zero-day attacks, phishing, and instant messaging (IM) attacks from mobile devices such as tablets and smartphones, which are often overlooked. 

5. IoT Security:- When utilizing Internet of Things (IoT) devices, organizations can enjoy increased productivity but face new cybersecurity risks. Malicious actors actively target vulnerable devices connected to the internet, exploiting them for unauthorized access to corporate networks or incorporating them into global bot networks.
