The Different Layers:-

In this rapid evolving world of AI, securing ourselves has become critically important. In order to Corden the security zone, one needs to combat cyber threats and safeguard their identity by understanding the 7 pivotal layers that form the bulwark against the ever-evolving landscape of cyber threats. In which, each layer offers distinct defence mechanisms to protect your valuable digital domains.

Given below is the list of seven layers of cybersecurity one must learn:-

1. Human Layer
2. Perimeter Layer
3. Network security Layer
4. Application Security Layer
5. Endpoint Security Layer
6. Data Security Layer
7. Mission critical assets

Lets understand each of them in detail:-

1. Human Layer:- The human layer, which emphasises the humane component of an organisation, is frequently thought of as the most vulnerable layer. It involves putting procedures and guidelines which guarantee that workers, subcontractors, and other users won’t be exposed to phishing scams and other security risks as a result of carelessness or ignorance. Strong password policies, multi-factor authentication, and security awareness training are a few examples of human layer security methods that make sure users can recognise and react to security risks.
2. Perimeter security Layer:- Perimeter security layer serves as the wall of fortress. By regulating incoming and outgoing network traffic in accordance with an organization’s previously set security policies, it helps to protect the network. In order to provide a barrier between your secure internal network and untrusted external networks, such the internet, it is fundamentally necessary to deploy firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), and virtual private networks (VPNs). A classic example of this is firewall that filters the incoming traffic thus preventing the unauthorized access to the network.
3. Network Layer:- Network Layer plays crucial role in managing and protecting the communication between applications and devices. This layer implements several security measures at the network level that prevent hackers from data breaching. Because of its high volume of information exchanges, it is extremely important and a prime target for cyber adversaries who want to intercept, alter, or interfere with the flow of data. Organisations can protect against unauthorised access and potential cyberattacks and maintain smooth and secure organisational operations by securing the network layer using techniques like encryption, secure protocols, and strong network architectures.
4. Application Security Layer:- This security layer protects and safeguards the software and devices from cyber threats. This includes securing the coding practices as the application layer serves the prime entry gate for the attackers.
5. End point Security Layer:-Protecting the individual devices that connect to the network, such as PCs, cell phones, and tablets, is the prime responsibility of the endpoint security layer. Securing these endpoints is essential because they act as network access points. Using antivirus software and endpoint detection and response (EDR) tools to keep an eye on, identify, and stop malicious activity and threats on endpoints is an example of endpoint security. This ensures that even in the event that a device is infected, the threat does not spread throughout the network.
6. Data Security Layer:- This layer is in charge of safeguarding the network’s data, with an emphasis on preserving its availability, secrecy, and integrity. One of the best examples of a data security technique is encryption, which transforms private information into a coded format to stop unwanted access. Using backup solutions and putting strong access controls in place are two more examples of how to protect data from exposure, loss, and unauthorised access while making sure that only authorised individuals have access to sensitive data.
7. Mission Critical Assets:- The protection of assets that are essential to an organization’s operations and business continuity is the main goal of this layer. These could consist of necessary hardware, private client information, or proprietary software. Implementing layered defences, such as firewalls, intrusion detection and prevention systems, and strong access restrictions, is part of the protection measures used here. For example, patching and updating mission-critical apps on a regular basis guarantees that vulnerabilities are fixed, reducing the possibility of exploitation and guaranteeing the continuous operation of vital resources.
