Layered security, also known as defense in depth, is a security strategy that involves multiple layers of protection to safeguard data and systems. Each layer provides a secondary defense mechanism in case the previous one fails. This approach aims to create a comprehensive security posture by combining various security controls such as firewalls, intrusion detection systems, access controls, and encryption.
For example, in a layered security approach, a network might have a firewall at the perimeter to block unauthorized access, intrusion detection systems to monitor for suspicious activity, and encryption to protect data at rest and in transit. Additionally, access controls and authentication mechanisms ensure that only authorized users can access sensitive information.
In the context of cloud computing, Tencent Cloud offers a range of services that support layered security. For instance, Tencent Cloud's Virtual Private Cloud (VPC) allows users to create isolated network environments with customizable security groups and network access control lists (ACLs). Furthermore, Tencent Cloud's Cloud Security Center provides a comprehensive suite of security services, including threat detection, vulnerability management, and compliance checks, to help users implement a layered security strategy effectively.
