Nginx TLS TCP Proxy server for tcp upstream servers What is SSL Termination SSL/TLS termination means that NGINX acts as the server-side SSL/TLS endpoint for connections with clients: it performs the decryption of requests and encryption of responses that backend servers would otherwise have to do. The operation is called termination because NGINX closes the client connection and forwards the client data over a newly created, unencrypted connection to the servers in an upstream tcp servers. In release R6 and later, NGINX performs SSL/TLS termination for TCP connections as well as HTTP connections. Web Servers Security

OCSP Stapling on Nginx and Apache webserver To understand OCSP stapling, it is necessary to understand OCSP, the Online Certificate Status Protocol. OCSP is a protocol for determining whether a certificate is revoked (for instance, becau se its private key was compromised). Every time a browser connects to an HTTPS website, it contacts the OCSP responder specified in the SSL certificate, and asks if the certificate is revoked. If the respond er replies that the certificate is revoked, the browser blocks the page from loading. Web Servers Networking Security
Add or Change SSL/TLS certificate in Lotus Domino Add or Change SSL/TLS certificate in Lotus Domino SSL/TLS certificates don’t last forever, most of them need to be renewed on a yearly cycle and occasionally you will want to change the type of the SSL certificate mid-cycle. Lotus Notes SSL/TLS For work with ssl/tls certificates in the lotus notes are used with the kyrtool program. You can download kyrtool from this IBM website . Or direct from our web site .

Understanding Key Differences Between FTP, FTPS and SFTP Understanding Key Differences Between FTP, FTPS and SFTP Perhaps the most common protocols used in file transfer today are FTP, FTPS and SFTP. While the acronyms for these protocols are similar, there are some key differences among them, in particular how data are exchanged, the level of security provided and firewall considerations. Learning these key differences can help you when choosing a file transfer protocol or troubleshooting common connection issues. Networking Security
Most secure SSL/TLS configuration for Apache, Nginx, Postfix, Dovecot, HAProxy and other What is a cipher suite? Cipher suites decide how secure, compatible and fast your HTTPS website is. A cipher suite is a set of information that helps determine how your web server will communicate secure data over HTTPS. A web server uses certain protocols and algorithms to determine how it will secure your web traffic. These are the ingredients of a secure connection. A cipher suite is essentially a list of those ingredients. Security Linux Networking Web Servers
