- Detailed explanation of Ubuntu server SSH security hardening strategy development process and reminders
- As an open source operating system, Ubuntu is widely used in the server field, and SSH (SecureShell), as a network protocol for remote management of servers, is one of the indispensable components of the Ubuntu server. Due to the openness of SSH The flexibility and powerful functions also bring potential risks to the security of the server. In order to protect the security of the Ubuntu server, a set of SSH security hardening strategies needs to be developed. Before formulating an SSH security hardening strategy, you first need to understand the working principle of SSH. SSH uses encryption and authentication technology to achieve secure remote access.
