7 Cybersecurity Layer Approaches to Anticipate Cyber Attacks
Cybersecurity should not just be a technology that enhances security but rather a multi-layered approach with multiple aspects used to ensure comprehensive protection. Each layer, from the outermost to the deepest, is essential to the overall defense strategy. This layered approach, commonly called 'defense in depth,' is critical for modern cybersecurity. So what are the procedures contained in these layers of security control?
This layered approach is fundamental to understanding, and there are generally seven layers of cybersecurity to consider. The following explains the seven layers of the security control approach.
Mission-Critical Assets
An asset that has substantial value to the organization and must be protected. The acquisition in question can be hardware, software, or data. Electronic medical records are an example of a critical asset in the healthcare industry. In the financial sector, it is a customer's financial records. Identifying and managing these assets is essential to prevent unauthorized access and misuse of assets.
Data Security
This layer includes the data security controls implemented to protect the process of transferring and storing data, and such protection can implement through practices such as encryption, archiving, access control, and regular backups. Data security is essential in all business sectors, as data breaches can have devastating consequences.
Endpoint Security
This layer ensures that endpoints (user devices connected to your network) are protected and not exploited by hackers. Protecting those endpoints with security software and regular updates can help prevent attacks that often target vulnerable entry points.
Application Security
This layer involves the application of controls to the host application to prevent, detect, and remove security vulnerabilities. It is the process of designing and configuring software code with security measures that continue to protect while the application is in use.
Application security features include authentication, authorization, encryption, logging, and application security testing.
Network Security
A network is the connection of all devices and how they share data. Network security protection can include implementing security policies and procedures and installing hardware and software that automatically detect and block network security threats (intrusion detection systems).
Network security measures include firewall protection, intrusion detection software, cloud security, and VPNs.\
Perimeter Security
It is protection from external threats (can be through a router or gateway) and aims to prevent unauthorized access by securing the boundaries of your network. You can control network access with strong firewall settings, implementing VPN for remote access, data encryption, network monitoring, secure devices, and vulnerability management.
The Human Layer
It is a critical layer to protect against threats posed by humans, cyber attackers, and malicious users to the organization. User education is necessary to ensure that users are knowledgeable about best practices for cybersecurity (recognizing and responding to security threats). Such as using secure passwords, two-factor authentication methods, and reporting malicious/suspicious activity.
Security-aware users can be one of your most robust defenses. Security is not a product but a process. Each layer of security controls is essential to the defense against cyber threats.
