Layers of the Cybersecurity Onion

[Elevator]

My favorite metaphor...
The layers of a cybersecurity "onion" typically include:

Network security: This layer involves protecting the infrastructure of a network, including routers, switches, and other hardware, as well as the protocols and technologies used to transmit data.

Endpoint security: This layer involves protecting individual devices, such as computers, smartphones, and tablets, from cyber threats. This may include measures such as antivirus software, firewalls, and device encryption.

Application security: This layer involves protecting the applications that run on devices, including web browsers, email clients, and other software. This may include measures such as input validation and secure coding practices to prevent vulnerabilities.

Data security: This layer involves protecting the data that is stored on devices and transmitted over networks. This may include measures such as encryption, access controls, and backup and recovery systems.

Identity and access management: This layer involves ensuring that only authorized users have access to resources and that their access is properly managed and monitored. This may include measures such as multifactor authentication and single sign-on.

User education and awareness: This outer layer involves educating users about cyber threats and best practices for avoiding them, as well as promoting a culture of security within an organization. This may include measures such as training programs and awareness campaigns.

Each layer of the cybersecurity onion works to provide additional protection and defense against cyber threats. By building multiple layers of protection, organizations can better protect themselves and their data from cyber attacks.
