用户认证协议(User Authentication Protocol):用户认证协议用于验证客户端用户的身份。在 SSH 连接建立之后,客户端需要提供有效的认证凭据(如用户名和密码、公钥等),以证明其具有访问服务器的权限。SSH 支持多种认证方法,包括基于密码的认证、基于公钥的认证和基于其他安全令牌的认证等。 连接协议(Conne
TCP, as described above, is a transport layer protocol, and one of the main ones used on the Internet. Another widely used transport layer protocol is UDP, the User Datagram Protocol. UDP is a "best-effort" transport protocol — sending packets without ensuring their delivery — which makes...
How user authentication works User authorization can take several forms. The client sends a user authentication service request that specifies the method of authentication—asymmetrical key authentication, passwords, or host-based verification. Many SSH users depend on the password method, which is comp...
How does the SSH protocol work The protocol works in the client-server model, which means that the connection is established by the SSH client connecting to the SSH server. The SSH client drives the connection setup process and uses public key cryptography to verify the identity of the SSH se...
Secure Shell (SSH) is a network protocol which uses a client-server architecture to establish secure, encrypted connections. Learn more about SSH with PAM360!

SSH is a crucial security protocol for any modern organization. Learn about its key components, how it works, and why you should prioritize its implementation with our comprehensive guide.
TLS, which stands for Transport Layer Security, is based in cryptography like Secure Shell Protocol. It operates on the transport layer of the OSI model. TLS works to secure data transmitted over networks in communications that expand beyond a local network, such as across the Internet. It work...
How SSH worksThis section uses SSH2 as an example to describe the stages to establish an SSH session.Table 1 Stages to establish an SSH sessionStages Description Connection establishment The SSH server listens to connection requests on port 22. After a client initiates a connection request, ...
4. By default, your system will have no SSH service enabled, which means you won't be able to connect to it remotely using SSH protocol (TCP port 22). This means that installing SSH server will be one of the first post-install steps on your system. ...
