6. Identity and Access Management (IAM)
This layer focuses on managing the identity of users and devices that access the organization’s network and resources. This includes measures such as authentication, access controls, and multi-factor authentication.
7. Cloud security
This layer focuses on protecting data and applications that are stored and run on cloud-based systems. This includes measures such as security protocols, encryption, and access controls.
8. Disaster recovery and business continuity
This layer focuses on the organization’s ability to maintain operations in the event of a disruption, such as a natural disaster or cyber attack. This includes measures such as disaster recovery planning and incident response.
Types of Cyber Security
Types of cyber security is a brief overview of the different aspects of cybersecurity that organizations and individuals need to be aware of in order to protect themselves from cyber threats. It covers the various types of cyber security such as
1. Network Security
This type of cybersecurity focuses on protecting the infrastructure of an organization’s network. Network security includes measures to secure the physical infrastructure of the network, such as routers and servers, as well as the logical infrastructure, such as protocols and data flow. Firewalls, intrusion detection systems, and virtual private networks (VPNs) are examples of network security measures. Network security is critical in protecting against threats such as denial-of-service (DoS) attacks, man-in-the-middle (MitM) attacks, and unauthorized access to sensitive data.
2. Application Security
This type of cybersecurity focuses on protecting the applications that run on a network. This includes web applications, mobile applications, and software applications. Application security includes measures to protect against vulnerabilities in the code of the application, such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF) attacks. It also includes measures to protect against unauthorized access to the application, such as authentication and access controls.
3. Endpoint Security
This type of cybersecurity focuses on protecting the devices that connect to a network, such as laptops, smartphones, and tablets. Endpoint security includes measures to protect against malware, such as antivirus software and intrusion detection systems. Firewalls are also implemented at the endpoint level to protect against unauthorized access to the device and the network. With the increasing use of mobile devices and the bring-your-own-device (BYOD) trend, endpoint security has become more important than ever.
4. Cloud Security
This type of cybersecurity focuses on protecting data and applications that are stored and run on cloud-based systems. Cloud security includes measures to protect against unauthorized access to cloud-based data and applications, such as security protocols, encryption, and access controls. It also includes measures to protect against threats to the cloud infrastructure, such as denial-of-service (DoS) attacks. With the increasing use of cloud-based services, cloud security has become a critical aspect of cybersecurity.
