Organisation file recovery tracking using smtp protocol
Abstract : E-mail system is one of the most ubiquitous Internet-based applications today. It enables users to send and receive E-mail messages among each other within and from outside of the local area network. E-mail system is used every day in almost all organizations as a communication tool between managers, employees, customers, and partners for better information flow and conduct business which requires communication with people outside the organization, or from different geographical locations. The E-mail system offers a fast, reliable and easy solution for such communication. SMTP (Simple Mail Transfer Protocol) is a transportation protocol used to transfer E-mail messages over the Internet. All E-mail servers use the SMTP to send E-mails from one E-mail server to another. SMTP is also used to send E-mail messages from E-mail clients to E-mail servers. In this paper, the SMTP E-mail system protocol will be briefly explained. New Active monitoring algorithm architecture is also proposed to improve the current E-mail system protocol functions and detect the SMTP protocol failure during the process of sending E-mail messages.
? The SMTP Service Extensions standard ( RFC 1425 ), which describes a process for adding new capabilities to extend how SMTP works while maintaining backward-compatibility with existing systems, was published.
? This includes support for existing platforms such as UNIX, Microsoft Windows, and Apple Macintosh, and future platforms such as Java Mail Service–based network computers.
? By connecting to the server and establishing an e-mail session, the user can download a temporary copy of his or her e-mail and read it, or send e-mail.
? The processes of retrieving e-mail from servers and managing data communication through the Internet are vulnerable to various attacks.
? If the Email server fails to send the 250 OK reply codes or send an error response, then the monitoring agent will generate a warning message to the network administrator indicating that the SMTP protocol has a problem.
? If the E-mail server responds using Error reply code, then generate a warning message to inform about the SMTP protocol problem.
? This monitoring algorithm is able to detect any problem that occurs during the monitoring period.
? This paper proposed an active E-mail system SMTP protocol monitoring algorithm using the active monitoring technique, to provide more efficient tools which are able to monitor the E-mail system protocol in realworking environment and detect any problems related to the SMTP protocol.
• The real-working environment monitoring results for the proposed E-mail system protocols monitoring algorithms are presented.
• Internet standard that provides the transfer of nontext information, such as sounds and graphics, and nonU.S. English (such as Cyrillic, Chinese, or Japanese) via e-mail.
• The fundamentals of SMTP, elements of its client–server architecture (user agent, mail transfer agent, ports), request–response mechanism, commands, mail transfer phases, SMTP messages, multipurpose internet mail extensions (MIME) for non-ASCII (American Standard Code for Information Interchange) data, e-mail delivery cases, mail access protocols (POP3 and IMAP4), SMTP software, some vulnerability and security issues, standards, associations, and organizations.
? Active network monitoring technique is one of the network monitoring techniques that works by sending packets from the monitoring agent to the server or application to measure the network performance and detect the network protocols’ failures.
? The monitoring algorithm did not detect any protocol failure during the monitoring time, whereas in other monitoring the proposed algorithm improved its efficiency, and accuracy in detecting all the E-mail system protocol error respond, delay respond, and failures to accomplish the monitoring design.
? SMTP (Simple Mail Transfer Protocol) is a transportation protocol used to transfer E-mail messages over the Internet.
? SMTP is also used to send E-mail messages from E-mail clients to E-mail servers.
