Computer

An Exchange server which resides in the DMZ and is used for routing of incoming and outgoing emails. The Edge Transport Server is typically not part of the Active Directory, although it may have a read-only snapshot. If the server has the edge transport role then it cannot have any other exchange roles.

An application that integrates with an email server, such as G Suite Gmail or Microsoft Exchange Server, to replicate, index and make messages (and their attachments, calendars and tasks) easily searchable. Safeguarding critical company data, compliance, record retention and setting up legal holds for litigation are common reasons for needing email archiving.

Encryption involves the process of transforming data so that it is unreadable by anyone who does not have a decryption key. The Secure Shell (SSH) and Socket Layer (SSL) protocols are usually used in encryption processes. The SSL/TLS drives the secure part of "https://" sites used in e-commerce sites, banking; today almost every web site available on Internet is using SSL/TLS protocol to protect traffic between endpoints. All data in SSL/TLS transactions is encrypted between the client (browser) and the server (web server) before the data is transferred between the two. All data in SSH sessions is encrypted between the client and the server when communicating at the shell. By encrypting the data exchanged between the client and server information like social security numbers, credit card numbers, and home addresses can be sent over the Internet with less risk of being intercepted during transit. Encryption should be used whenever people are giving out personal information to register for something or buy a product. Doing so ensures the person's privacy during the communication. Encryption is also often used when the data returned by the server to the client should be protected, such as a financial statement or test results.

Ephemeral means "lasting a very short time." In computing, an ephemeral object can be very useful: for instance, in cryptography an ephemeral key is a cryptographic key used only once and discarded very quickly, so it is generated for each execution of a key- establishment process and that meets other requirements of the key type (e.g., unique to each message or session). In some cases, ephemeral keys are used more than once within a single session (e.g., broadcast applications) where the sender generates only one ephemeral key pair per message, and the private key is combined separately with each recipient’s public key.

Software that monitors servers, workstations and network devices for routine and non-routine events. For example, routine events such as logins help determine network usage, while unsuccessful logins are warnings that crackers may be at work or that the network access system is failing. Event managers provide real-time information for immediate use and log events for summary reporting used to analyze network performance. An event management system is typically made up of client agents that reside in the remote devices, a central component for gathering the events, an event database and a reporting system to deliver the results in various formats.

In Explicit FTP over TLS, the FTP Client sends a specific command AUTH TLS to the FTP Server to establish the secure TLS Connection. The default FTP Control channel port 21 is used for secure TLS communication. Initially FTP Client connects to the server. and the FTP Client explicitly requests TLS encryption to turn on. User credentials are sent securely encrypted over the network for authentication in explicit FTP over TLS.
