What's the difference between SSL, TLS, and HTTPS?
Oct 6, 2011 · Namely, SSL protocol got to version 3.0; TLS 1.0 is "SSL 3.1". TLS versions currently defined include TLS 1.1 and 1.2. Each new version adds a few features and modifies some internal details. We sometimes say "SSL/TLS". HTTPS is HTTP-within-SSL/TLS. SSL (TLS) establishes a secured, bidirectional tunnel for arbitrary binary data between two hosts.
Security.stackexchange.comWhere exactly in the OSI model does TLS/SSL belong
Oct 7, 2018 · 2. Closed 6 years ago. I am trying to understand where exactly SSL/TLS sits in OSI model. If I look at this answer on StackExchange, While all network models are imperfect, this question can only be answered by looking at what SSL (TLS really) does. (1) On top of a reliable network stream (TCP at OSI layer 4) it provides an encrypted
Security.stackexchange.comWhat layer is TLS? - Information Security Stack Exchange
Jul 7, 2015 · SSL/TLS uses an underlying transport medium that provides a bidirectional stream of bytes. That would put it somewhere above layer 4. SSL/TLS organizes data as records, that may contain, in particular, handshake messages. Handshake messages look like layer 5. This would put SSL/TLS at layer 6 or 7. However, what SSL/TLS conveys is "application

Jan 13, 2011 · 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

Apr 22, 2016 · 3. Use public certs, but for internal addresses. This is a good option when using DNS validation, but it has a couple downsides, depending on your requirements: DNS management often lives in a very different place from where you need certificates (or with a different team!)— meaning you'll need all your ACME (ie.
Security.stackexchange.comtls - Should SSL be terminated at a load balancer? - Information
The expense with TLS is the building and closing of the connection, which the TLS offloader handles. On the backend you have a more persistent connection to the servers, and therefore the required resources are much lower. Additionally, if you don't have TLS offloading then even a small DDoS attack via TLS would completely annihilate your servers.
Security.stackexchange.comHow to determine if a browser is using an SSL or TLS connection?
There are several protocol versions : SSL 2.0, SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2. Internally, TLS 1.0/1.1/1.2 are SSL 3.1/3.2/3.3 respectively (the protocol name was changed when SSL became a standard). I assume that you want to know the exact protocol version that your browser is using. Internet Explorer
Security.stackexchange.comWhat are the differences between the versions of TLS?
Nov 22, 2010 · TLS 1.0 [..] This was an upgrade from SSL 3.0 and the differences were not dramatic, but they are significant enough that SSL 3.0 and TLS 1.0 don't interoperate. Some of the major differences between SSL 3.0 and TLS 1.0 are: Key derivation functions are different; MACs are different - SSL 3.0 uses a modification of an early HMAC while TLS 1.0

Dec 21, 2015 · Legacy and insecure SSL/TLS features (SSLv2 and SSLv3, SHA1RSA signatures, RC4 and 3DES ciphers, MD5 MAC, export ciphers, non PFS ciphers, <1024 DH parameters) are progressively being disabled by default and/or removed from browsers, and for good reason.
Security.stackexchange.comHow does SSL/TLS work? - Information Security Stack Exchange
Sep 28, 2012 · SSL (and its successor, TLS) is a protocol that operates directly on top of TCP (although there are also implementations for datagram based protocols such as UDP). This way, protocols on higher layers (such as HTTP) can be left unchanged while still providing a secure connection. Underneath the SSL layer, HTTP is identical to HTTPS.
