* Secure Shell protocol

Secure Shell ( SSH ) is a cryptographic network protocol for secure data communication, remote shell services or command execution and other secure network services between two networked computers that it connects via a secure channel over an insecure network: a server and a client ( running SSH server and SSH client programs, respectively ).

An example is a Unix server where multiple remote users have access ( such as via Secure Shell ) to the Unix shell prompt at the same time.

Common management methods include: a command-line interface ( CLI ) accessed via serial console, telnet or Secure Shell, an embedded Simple Network Management Protocol ( SNMP ) agent allowing management from a remote console or management station, or a web interface for management from a web browser.

* Secure remote password protocol ( SRP )

* Secure Shell ( SSH ) VPN-OpenSSH offers VPN tunneling ( distinct from port forwarding ) to secure remote connections to a network or inter-network links.

Secure copy or SCP is a means of securely transferring computer files between a local host and a remote host or between two remote hosts.

Juniper Secure Access products provide SSL-based VPN services to remote users through regular web browsers ( e. g. Mozilla Firefox ) on a variety of Java-enabled platforms ( Microsoft Windows, Mac OS, Linux, Apple iOS ).

* Secure remote password protocol ( SRP ) for TLS authentication

* Files transferred over shell protocol, a network protocol that uses Secure Shell ( SSH ) or Remote Shell ( RSH ) to transfer files between computers and manage remote files

Secure remote PC access and share applications for Windows.

** Secure remote access

* Secure Access Link ( SAL )-secure remote access and alarm reception

Other services include NFS for sharing files on a network, DHCP for dynamic IP address assignment, and Secure Shell for remote logins.

Encrypted communication for POP3 is either requested after protocol initiation, using the STLS command, if supported, or by POP3S, which connects to the server using Transport Layer Security ( TLS ) or Secure Sockets Layer ( SSL ) on well-known TCP port 995.

The STARTTLS extension allows the use of Transport Layer Security ( TLS ) or Secure Sockets Layer ( SSL ) to be negotiated using the STLS command, on the standard POP3 port, rather than an alternate.

Strong cryptography network protocols such as Secure Sockets Layer, I2P, and virtual private networks obscure the data transferred using them.

Secure free-space optical communications have been proposed using a laser N-slit interferometer where the laser signal takes the form of an interferometric pattern.

* Secure calls using standardized protocols ( such as Secure Real-time Transport Protocol ).

Secure voice over IP is accomplished by using Type 1 encryption on a classified network, like SIPRNet.

* Cryptographically Secure Random number on Windows without using CryptoAPI

The 802. 1X-2010 specification, which began as 802. 1af, addresses vulnerabilities in previous 802. 1X specifications, by using MACSec IEEE 802. 1AE to encrypt data between logical ports ( running on top of a physical port ) and IEEE 802. 1AR ( Secure Device Identity / DevID ) authenticated devices.

In February 2012, Imation announced a " unified Secure Data, Identity and Mobile Workspace product set " that includes solutions for securing mobile data, securing mobile identities and securing mobile workspaces – all based on the reality that employees are using portable storage devices to transport corporate data more and more.

Adaptive-chosen-ciphertext attacks were largely considered to be a theoretical concern until 1998, when Daniel Bleichenbacher of Bell Laboratories demonstrated a practical attack against systems using RSA encryption in concert with the PKCS # 1 v1 encoding function, including a version of the Secure Socket Layer ( SSL ) protocol used by thousands of web servers at the time.

" As a result, the " international " versions of web browsers were designed to have an effective key size of 40 bits when using Secure Sockets Layer to protect e-commerce.

TSA hoped to test Secure Flight in August 2005 using two airlines.

Secure operation was possible using Stunnel, and work on use of OpenSSL and other matters which were expected to provide full secure functionality were in progress.

It has been replaced by the STE ( Secure Terminal Equipment ) and other equipment using SCIP, the more modern Secure Communications Interoperability Protocol.

In 2005, Microsoft and Washington State successfully sued Secure Computer ( makers of Spyware Cleaner ) for $ 1 million over charges of using scareware pop-ups.

The ROS system allows companies and other business concerns who are liable for tax in the Republic of Ireland to file certain Tax Returns online using a Secure Site facility.

* NADSBox-New Age Digital Storage Box-Interfaces an SD media card using the Tandy TPDD drive protocol for portable storage and easy file transfers to a desktop computer using industry standard FAT formatted Secure Digital cards.

* Secure copy ( SCP ), a protocol for securely transferring files using the Secure Shell ( SSH ) protocol.
