FIRST, members must not supply CFIC with their company email addresses. That is, companies that they work for. (If you own the company, that's different.) All email on a company's server can be read by any supervisor. All it takes is one pro vaccine activist to get hold of our mobilization alerts to throw a monkey wrench in all of our efforts. Thus, do not supply me with a company email address. We can help you get an alternative to that if necesary. SECONDLY, CFIC needs members' email addresses to supply important information to mobilize parents to do things that advances our goal to enact our legislative reforms of the exemptions from vaccination. That has always been CFIC's sole agenda. CFIC has been able to keep the membership fee to zero because we don't communicate via snail mail. But people change their addresses frequently and forget to update CFIC. When this happens over the years, that member is essentually blind and deaf to us, and is no longer of any value to the coalition---your fellow parents. Therefore, it warrants me to require that members supply CFIC with their most permanent email account. That means the email address of the company in which you are paying a monthly fee for internet access, be it broadband or dialup service. -

Understanding Post Office Protocol (POP3)
Understanding Post Office Protocol (POP3) Author: Conrad Chung, 2BrightSparks Introduction Most Internet users with email accounts would have used some form of “client” software (Outlook, Thunderbird etc.) to access and manage their email at one point or another. To retrieve emails, these email clients may require the configuration of Post Office Protocol (or POP3) before messages can be downloaded from the server. This article will help readers understand what POP3 is and how it works. What is Post Office Protocol? The Post Office Protocol (POP3) is an Internet standard protocol used by local email software clients to retrieve emails from a remote mail server over a TCP/IP connection. Since the first version was created in 1984, the Post Office Protocol (currently at Version 3) has since became one of the most popular protocols and is used by virtually every email client to date. Its popularity lies in the protocol’s simplicity to configure, operate and maintain. Email servers hosted by Internet service providers also use POP3 to receive and hold emails intended for their subscribers. Periodically, these subscribers will use email client software to check their mailbox on the remote server and download any emails addressed to them. Once the email client has downloaded the emails, they are usually deleted from the server, although some email clients allow users to specify that mails be copied or saved on the server for a period of time. Email clients generally use the well-known TCP port 110 to connect to a POP3 server. If encrypted communication is supported on the POP3 server, users can optionally choose to connect either by using the STLS command after the protocol initiation stage or by using POP3S, which can use the Transport Layer Security (TLS) or Secure Sockets Layer (SSL) on TCP port 995 to connect to the server. -

Toward an Automated Vulnerability Comparison of Open Source IMAP Servers Chaos Golubitsky – Carnegie Mellon University
Toward an Automated Vulnerability Comparison of Open Source IMAP Servers Chaos Golubitsky – Carnegie Mellon University ABSTRACT The attack surface concept provides a means of discussing the susceptibility of software to as-yet-unknown attacks. A system’s attack surface encompasses the methods the system makes available to an attacker, and the system resources which can be used to further an attack. A measurement of the size of the attack surface could be used to compare the security of multiple systems which perform the same function. The Internet Message Access Protocol (IMAP) has been in existence for over a decade. Relative to HTTP or SMTP, IMAP is a niche protocol, but IMAP servers are widely deployed nonetheless. There are three popular open source UNIX IMAP servers – UW-IMAP, Cyrus, and Courier-IMAP – and there has not been a formal security comparison between them. In this paper, I use attack surfaces to compare the relative security risks posed by these three products. I undertake this evaluation in service of two complementary goals: to provide an honest examination of the security postures and risks of the three servers, and to advance the study of attack surfaces by performing an automated attack surface measurement using a methodology based on counting entry and exit points in the code. Introduction Contributions and Roadmap System administrators frequently confront the The paper makes two major contributions. First, problem of selecting a software package to perform a I undertake an in-depth discussion of the relative secu- desired function. Many considerations affect this deci- rity postures of the three major open source IMAP sion, including functionality, ease of installation, soft- servers in use today. -
Chapter 1. Origins of Mac OS X
1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years. -
Web Browser a C-Class Article from Wikipedia, the Free Encyclopedia
Web browser A C-class article from Wikipedia, the free encyclopedia A web browser or Internet browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content.[1] Hyperlinks present in resources enable users to easily navigate their browsers to related resources. Although browsers are primarily intended to access the World Wide Web, they can also be used to access information provided by Web servers in private networks or files in file systems. Some browsers can also be used to save information resources to file systems. Contents 1 History 2 Function 3 Features 3.1 User interface 3.2 Privacy and security 3.3 Standards support 4 See also 5 References 6 External links History Main article: History of the web browser The history of the Web browser dates back in to the late 1980s, when a variety of technologies laid the foundation for the first Web browser, WorldWideWeb, by Tim Berners-Lee in 1991. That browser brought together a variety of existing and new software and hardware technologies. Ted Nelson and Douglas Engelbart developed the concept of hypertext long before Berners-Lee and CERN. It became the core of the World Wide Web. Berners-Lee does acknowledge Engelbart's contribution. The introduction of the NCSA Mosaic Web browser in 1993 – one of the first graphical Web browsers – led to an explosion in Web use. Marc Andreessen, the leader of the Mosaic team at NCSA, soon started his own company, named Netscape, and released the Mosaic-influenced Netscape Navigator in 1994, which quickly became the world's most popular browser, accounting for 90% of all Web use at its peak (see usage share of web browsers).
