Created in 1990 by Tim Berners- Lee, the web quickly became the most used hypertext system in the world, and most browsers default to indicating hyperlinks with an underline. To answer the question of why the underline was chosen over competing demarcation techniques, the thesis applies the methods of history of technology and sociology of technology. Before the invention of the web, the underline–also known as the vinculum–was used in many contexts in writing systems; collecting entities together to form a whole and ascribing additional meaning to the content. -
Usenet Gopher
Usenet Usenet is a worldwide distributed discussion system. It was developed from the general-purpose UUCP dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in !"#"$ and it was established in !"%&.'!( Users read and post messages (called articles or posts$ and collectively termed news* to one or more categories$ known as newsgroups. Usenet resembles a bulletin board system )++,* in many respects and is the precursor to Internet forums that are widely used today. Usenet can be superficially regarded as a hybrid between email and web forums. .iscussions are threaded$ as with web forums and ++,s$ though posts are stored on the server sequentially. Usenet is a collection of user-submitted notes or messages on various subjects that are posted to servers on a worldwide network. Each subject collection of posted notes is known as a newsgroup. There are thousands of newsgroups and it is possible for you to form a new one. 1ost newsgroups are hosted on Internet-connected servers$ but they can also be hosted from servers that are not part of the Internet. 2opher 3 system that pre-dates the 4orld 4ide 4eb for organizing and displaying -les on Internet servers. 3 Gopher server presents its contents as a hierarchically structured list of -les. 4ith the ascendance of the 4eb, many gopher databases were converted to 4eb sites which can be more easily accessed via 4eb search engines . The Gopher protocol is a TCP/IP application layer protocol designed for distributing, searching$ and retrieving documents over the Internet. The Gopher protocol was strongly oriented towards a menu-document design and presented an alternative to the 4orld 4ide 4eb in its early stages$ but ultimately 7TTP became the dominant protocol. -

Ipsec, SSL, Firewall, Wireless Security
IPSec 1 Outline • Internet Protocol – IPv6 • IPSec – Security Association (SA) – IPSec Base Protocol (AH, ESP) – Encapsulation Mode (transport, tunnel) 2 IPv6 Header • Initial motivation: – 32-bit address space soon to be completely allocated. – Expands addresses to 128 bits • 430,000,000,000,000,000,000 for every square inch of earth’s surface! • Solves IPv4 problem of insufficient address space • Additional motivation: – header format helps speedy processing/forwarding – header changes to facilitate QoS IPv6 datagram format: – fixed-length 40 byte header – no fragmentation allowed 3 IPv6 Header (Cont) Priority: identify priority among datagrams in flow Flow Label: identify datagrams in same “flow.” (concept of“flow” not well defined). Next header: identify upper layer protocol for data 4 Other Changes from IPv4 • Checksum: removed entirely to reduce processing time at each hop • Options: allowed, but outside of header, indicated by “Next Header” field • ICMPv6: new version of ICMP – additional message types, e.g. “Packet Too Big” – multicast group management functions 5 IPv6 Security – IPsec mandated • IPsec is mandated in IPv6 – This means that all implementations (i.e. hosts, routers, etc) must have IPsec capability to be considered as IPv6-conformant • When (If?) IPv6 is in widespread use, this means that IPsec will be installed everywhere – At the moment, IPsec is more common in network devices (routers, etc) than user hosts, but this would change with IPsec • All hosts having IPsec => real end-to-end security possible 6 IPv6 Security • Enough IP addrs for every imaginable device + Real end-to-end security = Ability to securely communicate from anything to anything 7 IPv6 Security – harder to scan networks • With IPv4, it is easy to scan a network – With tools like nmap, can scan a typical subnet in a few minutes see: http://www.insecure.org/nmap/ – Returning list of active hosts and open ports – Many worms also operate by scanning • e.g. -
SILC-A SECURED INTERNET CHAT PROTOCOL Anindita Sinha1, Saugata Sinha2 Asst
ISSN (Print) : 2320 – 3765 ISSN (Online): 2278 – 8875 International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering Vol. 2, Issue 5, May 2013 SILC-A SECURED INTERNET CHAT PROTOCOL Anindita Sinha1, Saugata Sinha2 Asst. Prof, Dept. of ECE, Siliguri Institute of Technology, Sukna, Siliguri, West Bengal, India 1 Network Engineer, Network Dept, Ericsson Global India Ltd, India2 Abstract:-. The Secure Internet Live Conferencing (SILC) protocol, a new generation chat protocol provides full featured conferencing services, compared to any other chat protocol. Its main interesting point is security which has been described all through the paper. We have studied how encryption and authentication of the messages in the network achieves security. The security has been the primary goal of the SILC protocol and the protocol has been designed from the day one security in mind. In this paper we have studied about different keys which have been used to achieve security in the SILC protocol. The main function of SILC is to achieve SECURITY which is most important in any chat protocol. We also have studied different command for communication in chat protocols. Keywords: SILC protocol, IM, MIME, security I.INTRODUCTION SILC stands for “SECURE INTERNET LIVE CONFERENCING”. SILC is a secure communication platform, looks similar to IRC, first protocol & quickly gained the status of being the most popular chat on the net. The security is important feature in applications & protocols in contemporary network environment. It is not anymore enough to just provide services; they need to be secure services. The SILC protocol is a new generation chat protocol which provides full featured conferencing services; additionally it provides security by encrypting & authenticating the messages in the network. -

Secure Shell Encrypt and Authenticate Remote Connections to Secure Applications and Data Across Open Networks
Product overview OpenText Secure Shell Encrypt and authenticate remote connections to secure applications and data across open networks Comprehensive Data security is an ongoing concern for organizations. Sensitive, security across proprietary information must always be protected—at rest and networks in motion. The challenge for organizations that provide access to applications and data on host systems is keeping the data Support for Secure Shell (SSH) secure while enabling access from remote computers and devices, whether in a local or wide-area network. ™ Strong SSL/TLS OpenText Secure Shell is a comprehensive security solution that safeguards network ® encryption traffic, including internet communication, between host systems (mainframes, UNIX ™ servers and X Window System applications) and remote PCs and web browsers. When ™ ™ ™ ™ Powerful Kerberos included with OpenText Exceed or OpenText HostExplorer , it provides Secure Shell 2 (SSH-2), Secure Sockets Layer (SSL), LIPKEY and Kerberos security mechanisms to ensure authentication security for communication types, such as X11, NFS, terminal emulation (Telnet), FTP support and any TCP/IP protocol. Secure Shell encrypts data to meet the toughest standards and requirements, such as FIPS 140-2. ™ Secure Shell is an add-on product in the OpenText Connectivity suite, which encrypts application traffic across networks. It helps organizations achieve security compliance by providing Secure Shell (SSH) capabilities. Moreover, seamless integration with other products in the Connectivity suite means zero disruption to the users who remotely access data and applications from web browsers and desktop computers. Secure Shell provides support for the following standards-based security protocols: Secure Shell (SSH)—A transport protocol that allows users to log on to other computers over a network, execute commands on remote machines and securely move files from one machine to another. -
