Questions
Internet security can be divided into two categories: access security and transaction security. Access Security relates to the corporation’s ability to protect its computers, memory, disk, printer and other devices from unauthorized use. Transaction Security relates to the ability of two entities on the Internet to conduct a transaction privately, and with authentication and digital signatures, if required. Secure HTTP and an SSL security device are mechanisms for transaction security on the web. With a move to connected devices, SSL and SSH are internet security software mechanisms that can be used to ensure remote management and configuration of connected devices is handled securely. why do I need Internet security software on my devices? Connected, embedded devices and device management must be secure. Connected embedded devices are core to many business processes - if their security is compromised, your network is also at risk. If you ship unsecured devices to your customers, you are putting their business processes and network at risk as well. Customer requirements to improve device security are placing new demands on web based and command-line interface (CLI) device management software. An embedded SSL security device and SSH security servers addresses these demands. what is SSL? TCP/IP, the internal communications protocol for all Internet applications (e-mail, usenet, World-Wide Web), uses a programming abstraction called a socket to implement reliable transport between two parties on the Internet. Secure Sockets Layer (SSL), developed by Netscape Communications, is a security-enhanced abstraction of sockets that provides transaction security at the link or transport level. With an SSL security device, security properties are attached to the link or channel of communication between two parties, not the documents themselves. what is SSH? SSH stands for Secure Shell.Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over insecure channels. It is a replacement for rlogin, rsh, rcp, and rdist. SSH Internet security software protects a network from attacks such as IP spoofing, IP source routing, and DNS spoofing. An attacker who has managed to take over a network can only force SSH to disconnect, not play back the traffic or hijack the connection when encryption is enabled. When using SSH's slogin (instead of rlogin) the entire login session, including transmission of password, is encrypted. Therefore it is almost impossible for an outsider to collect passwords. SSH is available for:
Encrypting a document means to scramble the contents using sophisticated and proven mathematical formulas. There are a variety of well-accepted algorithms for performing this encryption process that have been proven secure over many years through rigorous testing. Encryption is usually based on the application of a numeric key that ensures that the document is scrambled in a manner that can be reversed through the application of another numeric key. Without the proper key (a very long string of digital characters) the document cannot be unscrambled. The encryption process is performed programmatically by special Internet security software that is built into applications. The algorithm and key are combined to create an encrypted file of the original document. Protecting electronic keys is very important. In the same way as a metal key can unlock a home’s front door to anyone possessing the key, encrypted digital files can be decrypted by anyone with the proper digital key. what is a digital certificate? A digital certificate is a unique identifier for an individual - very similar in principle to a US Social Security number, a driver’s license or passport. It is a document issued by a trusted authority that certifies the identity of the carrier. For a driver’s license, the authority is the state and the carrier is the driver. The state uses features like stamps or holograms on the document that prevents counterfeiting of the document. For a digital certificate, the authority is a CA (Certificate Authority) and the carrier is the user, usually a computer, a web site or an institution. The CA uses digital signatures to prevent counterfeiting of the certificate. The digital certificate contains a cryptographic key that allows information to be sent that can only be understood by the certificate carrier.
