Cyber Security: Types, Examples, Layers

Introduction to Cybersecurity 

Cybersecurity is the practice of protecting an organization’s computers, networks, devices, and sensitive data against cyber-attacks by utilizing technology, procedures, and good IT habits. Businesses can no longer afford to ignore cybersecurity knowledge and resiliency. Cybersecurity has transformed from an IT challenge to a business concern for today’s digital organizations. 

According to research, over 30,000 websites are attacked worldwide every day, and 64% of businesses have experienced one or more cyber-attacks. If you own a business that involves the use of a computer and the web in any sense, you will almost certainly face a cyber-attack at some time. 

In this blog, we will understand cybersecurity, types of cyber security, layers Of Cybersecurity, and much more. 

What is Cyber security? 

Cyber security is a procedure that safeguards networks and devices against external attacks.  

The industry standard of confidentiality, integrity, and availability governs the field of cyber security. Confidentiality implies that allowed parties can only view data. integrity implies that information can only be added, edited, or withdrawn by authorized users. Availability implies that systems, services, and data must be accessible on demand within agreed-upon standards. 

Why Do We Need It?  

Cybercrime is becoming a severe issue, and robust cybersecurity is essential to combating it. 

Cyberattacks and security breaches threaten users, governments, for-profit enterprises, non-profit organizations, healthcare, schools and universities, and much more. As digital technology progresses, the number of gadgets and users increases, global supply chains get more complicated, and data becomes more vital in the digital economy, the number of assaults will rise. Strong cybersecurity is required to reduce the danger of an attack and safeguard systems and data. 

Types Of Cybersecurity  

It is critical to understand the various types of Cybersecurity so that businesses can identify which aspects are vulnerable and which risks need to be addressed. 

The following are the most common types of Cybersecurity that firms must concentrate on: 

  • Network Security  

Network security confines a range of technology, equipment, and procedures. It is a collection of rules and configurations that are established and applied to secure the confidentiality, integrity, and accessibility of both networks and data. Network security is built to protect internal networks from intruders by safeguarding critical infrastructure security. Using updated, complex passwords and two-factor authentication are excellent cyber security examples of network security. 

  • Cloud Security  

Cloud security refers to the techniques, applications, processes, and policies that strive to protect cloud data, networks, and operations against cyber threats and assaults. Continually securing and tracking data in the cloud assists in eliminating any risks associated with on-premises intrusions. 

  • Endpoint Security  

Endpoint security prevents hostile entities and operations from exploiting endpoints or entry points of end-user devices such as PCs, laptops, and portable devices. Endpoint security solutions safeguard against perils on a network or in the cloud. Endpoint security has progressed from simple antivirus software to complete protection against complex malware and developing zero-day vulnerabilities. 

  • Mobile Application Security   

Mobile Application Security, also referred to as wireless security, is the safeguards in place to secure cellphones, computers, tables, and other portable devices, as well as the networks to which they are linked, from the threats and hazards associated with wireless technology. 

  • Internet of Things Security 

It is defined as a cybersecurity strategy and defense mechanism that protects against cyberattacks, particularly targeting tangible IoT devices linked to the network. Without strong security, every networked IoT device is susceptible to a malicious attacker’s breach, exploitation, and manipulation, allowing them to eventually invade, acquire user data, and take systems down. 

  • Application Security   

Application security employs software and technology to safeguard and protect applications from dangers during development. Firewalls, encryption, and antivirus software are some of the cyber security examples of Application security. 

  • Zero Trust  

Zero Trust is a security architecture that requires all users, both within and outside an organization’s network, to be verified, approved, and continually checked for configuration and posture before being permitted or maintaining access to apps and information. Zero Trust presupposes that there is no conventional network perimeter; connections can be local, in the cloud, or hybrid, with resources and employees located everywhere. 

Layers Of cybersecurity  

Cybersecurity is not a standalone system that enhances security. It is a multi-faceted approach that ensures full protection. 

It’s critical to grasp what a layered approach entails. There are seven layers of cybersecurity to consider.  

  • Mission Critical Assets  

This is everything your company cannot function without. Operating systems, electronic medical records, productivity tools, financial information, and cloud infrastructure are all included. The difficulty at this layer is that what is vital for one firm may not be essential for another. That implies you must first decide what your company cannot function without and then move back to safeguard it.  

  • Data Security   

When security rules are set up to secure the flow and storage of data, this is referred to as data security. A backup security solution is placed to prevent data. This also needs the usage of encryption and archiving.Data security is a priority for all firms, as a data leak may have disastrous implications. 

  • Application Security   

This includes the security elements that govern application access and the application’s access to your resources. It also contains the application’s internal security. Most applications are built with security safeguards that ensure the safety of the user when the application is in use. 

  • Endpoint Security    

This layer of security ensures that intrusions do not abuse user device endpoints. This covers mobile devices, desktop computers, and laptop computers. Endpoint security solutions protect a network or in the cloud based on organizational requirements. 

  • Network Security   

This is where security controls are implemented to secure the company’s network. The purpose is to prevent unauthorized network access. It is critical to keep all systems on the company network up to date with the essential security fixes, including encryption. To better protect against attacks, it is always preferable to deactivate redundant connections. 

  • Perimeter Security  

This security layer implies that both tangible and digital security solutions safeguard the whole enterprise. It contains firewalls, which safeguard the company network from outside threats. 

  • The Human Layer  

It includes management controls and phishing simulations. These human management controls strive to secure the most crucial aspects of a company’s protection. This encompasses significant danger posed to a firm by individuals, cyber attacks, and malicious users. 

Conclusion 

Cyber security measures combined with a knowledgeable and aware user base provide the best protection against cyber attacks. The best approach to combat malicious threats and assaults is to allow security systems to evolve better and combat the advanced threats, and prevent attacks from advancing in the first place.
