2011年1月13日 · If you really looking for SSH vs SSL(TLS) then the answer is SSH. For one reason why SSH wins over SSL is the way it performs Authentication. Because of this reason when using FTP use SSH protocol (SFTP) rather then FTPS (FTP over SSL). SSH is used in corporate networks for: providing secure access for users and automated processes

I would be very worried about a security "expert" who thinks that the terms SSH and VPN apply to the same functionality. I assume that the tale has lost something in the retelling. VPN simply means an encrypted network connection. There are multiple technologies which can deliver that; TLS, PPTP, and even SSH amongst other things.

2011年10月6日 · SSL VS TLS. The terms SSL and TLS are often used interchangeably or in conjunction with each other (TLS/SSL), but one is in fact the predecessor of the other — SSL 3.0 served as the basis for TLS 1.0 which, as a result, is sometimes referred to as SSL 3.1. Which is more Secure SSL or TLS. In terms of security they both are consider equally ...

For this "tunnelling" part, IPsec does things correctly, and so does TLS (assuming TLS 1.1 or 1.2, for IV selection with block ciphers in CBC mode). In fact IPsec can be deemed to be "more correct" than TLS because it uses encrypt-then-MAC instead of MAC-then-encrypt (see this); however, properly implemented TLS 1.1 or 1.2 will be fine too ...

You are still negotiating TLS with the real server at the other end, and the situation is pretty much the same as #1 above. You don't need to do TLS over the TCP connections, actually; you could simply CONNECT server.mydom.com:22 and start talking SSH over that connection if the proxy doesn't reject that request. Some people have SSH servers ...

2020年8月27日 · I have an odd case where a vulnerability scan is reporting that sshd is vulnerable because of TLS. I didn't think SSH used TLS, so can someone help me explain why "openssl s_client -connect

The Hearbleed security bug (CVE-2014-0160) affects only specific versions of OpenSSL, and nothing else.From OpenSSL Security Advisory [07 Apr 2014], on OpenSSL's web site:

2022年12月16日 · The fact that the SSH server listens on port 22 does not make it necessarily directly discoverable; you can block access to that port from the internet and only allow local access by using firewall rules (allowing access from your web server, but blocking it …

2016年9月29日 · Transport security like TLS, VPN, or SSH is used to secure trusted users when connecting through untrusted network. They cannot secure systems from untrusted users. If you have untrusted users that need access to the database, the traditional way to do this securely is to wrap the database in an application layer.

2020年2月28日 · SSH symmetric cipher can be 3DES, AES-CBC, AES-CTR, AES-GCM, CHACHA20-POLY1305. SSH symmetric MAC can be AEAD (GCM, Poly1305) or HMAC or UMAC. If you compare this to TLS, especially the modern options, you'll see they are the same. ECDHE over P-256 and Curve25519 is the same and the recommended key exchange in both.
