5 Types of Cyber Security & Its Explanation

Cybersecurity helps protect systems that are connected to the internet, like software, hardware, and confidential data, against cyber-attacks. According to Purplesec, Cyber Security can prevent you from falling into the category of 7.1 million people who suffer due to cybercrime annually.  Cyber Security offers a layer of protection to computerised systems and data centres by blocking unauthorised access. 

Thus, organisations should have a strong Cyber Security strategy to minimise malicious attacks aiming to alter, destroy, extort, or delete a user’s sensitive data by gaining unauthorised access to their systems. Cyber Security also prevents attacks designed to disable a system’s operations.

What is Cyber Security? 

People are becoming more dependent on the internet. They use the internet to handle all major and minor tasks. Top organisations mainly advertise and sell their products digitally through the internet.   

As a result, cybercriminals are using this as an opportunity to carry out cyber-attacks and spread malware with the help of the internet. To minimise such attacks, cyber experts are using Cyber Security practices. So, let’s understand the meaning of Cyber Security.  

Cyber Security includes a series of safety protocols that shield programs, devices, data, and networks by blocking unauthorised access. Also, it prevents third-party attackers from modifying important data recorded on the IT infrastructure of organisations.  

The third-party attacks are carried out digitally. These attacks can delete, alter, and steal sensitive information through unauthorised access.

What are the types of Cyber Security?  
 

Cyber Security aims to protect an organisation’s assets and employees against cyber-attacks. Due to the growing complexity of corporate networks, there’s an increase in cyber-attacks. Let’s learn about the 5 Cyber Security types and how they can minimise cyber threats:  

Network Security 

Network Security includes practices and control systems that can secure the originality of the networking infrastructure. These practices are used to defend the data and network against threats, breaches, intrusions, unauthorised access, misuse, etc. The control systems are divided into the following three types: 

1) Technical: It helps secure the data stored in the network or still in transit. 

2) Physical: It helps to secure the network infrastructure, such as routers, servers, and data centres, against unauthorised physical access.  

3) Administrative: It includes the safety policies and measures to control an organisation’s network access. 

Some of the common threats that can impact your network are as follows: 

1) Viruses and malware 

2) Insider attacks (carried out by contractors or employees) 

3) Distributed Denial of Service (DDoS) attacks and Denial of Service (DoS) 

The common types of Network Security that help to minimise such threats are as follows: 

1) Firewalls: Firewalls keep track of the volume of traffic that moves across the network. It blocks unauthorised traffic as per the policies or rules you’ve set.  

2) Virtual Private Networks: Virtual Private Networks secure the process of data transmission. It also protects the network against unauthorised access with the help of techniques like traffic eavesdropping. 
 

Cloud Security 

Cloud Security includes policies, processes, and technologies used to minimise risks related to cloud computing. The most common security solutions helpful in securing hybrid, private, and public clouds are as follows: 

1) Cloud access security broker: One of the significant reasons behind data leaks and data breaches in the cloud are misconfigurations. A CASB helps to find out misconfigurations and secure access controls.  

2) Identity and access management: The solution helps to block unauthorised access by verifying the identity of users across the cloud infrastructure.  

3) Multi-factor authentication: Multi-factor works as a security layer for the entire environment. It especially helps users to access cloud applications and similar resources safely.

Endpoint Security 

The rising trend of bringing your own device (BYOD), remote work, and workplace mobility is pressuring organisations to secure their endpoints. Some of the best practices to prevent this are as follows: 

1) Endpoint Protection Platforms: The two types of commonly used EPP solutions are antimalware and antivirus. These solutions minimise signature-based attacks by preventing the threats from gaining unauthorised access inside the endpoint.  

2) Endpoint Detection and Response platforms: EDR helps discover threats that Endpoint Protection Platforms cannot block. 

3) Disk encryption: Disk encryption secures the privacy of the data being accessed by the attacker by converting it into a useless format. Encryption secures information which is being accessed in an unauthorised way through physical means. Similarly, it protects data against attacks carried out through the internet, such as cyberattacks.  

4) Mobile Device Management (MDM): Mobile devices are exposed to severe risks. So, the objective of MDM is to protect these devices against data leaks, hacking, or similar threats. MDM can be integrated with the identity and access management solution to minimise such risks.  

Application security 

Application security is vulnerable to risks like DDoS attacks, weak access controls, encryption issues, misconfigurations, SQL or similar code injections. These risks can be minimised by adopting the following solutions: 

1) SaaS management: Organisations willing to secure their cloud applications should switch to a SaaS management strategy. Organisations find it challengng to secure applications that aren’t visible. So, SaaS management allows organisations to identify cloud applications and implement access policies.  

2) Risk evaluation and updating: One of the easiest steps to prevent a data breach is to update software and applications. Several organisations need help to patch and update their software regularly. Thus, risk evaluation helps organisations to rank important updates on high priority.  

3) Access controls: It’s essential to keep track of users who have access to applications frequently. It helps to reduce security risks. You can get started by adopting cloud governance if you want to monitor access controls. Cloud governance helps to organise and automate security policy enforcement strategies.

Internet security 

Most data breaches occur due to attacks carried out through the internet. If you want to minimise internet-borne attacks in your organisation, you can implement the below-mentioned Cyber Security measures: 

1) DNS- layer security: Devices infected due to phishing, botnet, and malware attacks try to form a bond with the command-and-control centre. Organisations can prevent these threats from impacting the environment by blocking the requests from such devices on the internet.  

2) Email security: Phishing is a major cyber threat that impacts organisations' data worldwide. Organisations can minimise phishing attacks by preventing employees from clicking on emails containing malicious attachments and links. Additionally, organisations can improve Email security by encrypting sensitive messages and blocking suspicious emails.  

3) URL filtering: URL filtering allows organisations to keep an eye on the different types of websites that their employees have access to. As a result, organisations can identify risky websites by evaluating their content. Organisations can block these websites to minimise risks.  
 

Conclusion  

Individuals, governments, and businesses store large amounts of data on their cloud computing networks and computers. However, this data is vulnerable to data breaches.  To minimise the risks related to data breaches. The implementation of different types of Cyber Security strategies and tools is recommended to minimise the risks related to data breaches.  to learn more about Phishing, Web Security, and Hacking, check out our Certified Cyber Security Professional (CCS-PRO) course today!
