Google in stealth mode

Google has launched the secure version of its iconic search engine, where all traffic is encryptedusing SSL (Secure Sockets Layer) and can't be snooped upon by search-habit analysts or network snoopers. Google has killed three birds with one shot:

First, it silenced the critics, who earlier this week accused Google's ad agency, DoubleClick, of collecting user data from social networking sites. Google has shown its commitment to safeguarding the privacy of users.

Second, it warded off the search-habit analysts who've been using the referral addresses to see what keywords were searched, to reach which site. This allows sites to edit meta-tag data to push their sites higher up the search order. Most browsers remove these referrers when navigating from a secure site to an insecure one.

Third, it put itself further ahead of its rival search engines - now that users would prefer Google as it would safeguard them on the local network, even when the network is insecure. So they will avoid passing information to agencies, err...like Google. Yes, it would certainly help Google's case in Street View Car debacle where the camera-fitted cars collected user data through insecure WiFi connections in homes.

The secure search engine is currently in the Beta stage and can be reached at https://www.google.com (notice the extra 'S'). It's in Beta stage to undergo tests regarding its feasibility in establishing secure, encrypted connections can increase the search time and also bog down the servers.

Fibre Channel Glossary

D L P B C : Dual Loop Port Bypass Circuitry. FC-AL routing circ u i t ry that makes it possible to add and remove nodes without disrupting the network.

Dynamic path: Communication path in which any node can communicate with any other node (assuming no third node is already communicating with the target). See Permanent path.

E-port: A connection that links multiple Fibre Channel fabrics.

F a b r i c : Fibre Channel communication network topology, typically with 16 nodes, each of which can be an FC-AL comprising 125 nodes. A Fibre Channel fabric usually employs a Fibre Channel switch or crossbar switch to provide direct connections between node pairs.

FC adapter: Fibre Channel adapter or host adapter. A Fibre Channel I/O bus adapter board that operates at 100MBps in half-duplex mode, 200MBps in full-duplex mode.

F C - A L : Fibre Channel Arbitrated Loop. A ring-style network topology comprising 125 nodes, usually configured as a double loop to protect the system against device failure.

F C S I : Fibre Channel Systems Initiative formed by Hewlett-Packard, IBM, and Sun in 1993.

FC switch: Fibre Channel switch. Intelligently manages connections between ports, routing frames d y n a m i c a l l y. A nonblocking topology, it allows multiple exchanges of information to occur at the same time between ports. A switch offers better system throughput than a hub, but at greater expense. Some switches have a special FL-port to link arbitrated loops and other devices on the switch. By cascading multiple switches, more than 16 million devices can be connected together.

F r a m e : Data packet, a unit of data transmitted within a Fibre Channel system.

F - p o rt : Port that connects a node to a Fibre Channel fabric.

F L - p o rt : Port that connects an FC-AL to a fabric.

Hub: Cable concentrator for FC-AL networks. A hub is a static device that monitors each of its ports to determine whether devices are requesting to join the loop. It does not route frames dynamically.

J B O D : Just a bunch of drives. Any collection of disk drives not configured into a RAID.

L I P : Loop Initialization Protocol. Part of the FC-AL standard for reconfiguring the system when nodes are added or removed from the loop.

LRC: Loop Resiliency Circuit. Hub circuitry that allows devices to be inserted into or removed from an active FC-AL loop.

M I A : Media Interface Adapter. Converts electrical signals into optical signals and vice versa.

N o d e : Device connected to a Fibre Channel fabric, possibly a PC, disk drive, or RAID array, as well as an FC-AL.

N - p o rt : Port that connects a node to Fibre Channel system. In a PC, the N-Port would be on an I/O bus adapter board.

N L - p o rt : Port that connects a node to an FC-AL.

Permanent path: Fixed communication path be-tween nodes that provides guaranteed bandwidth. See Dynamic path.

Port: Locus of connection between a node and a Fibre Channel system.

S A N : Storage Area Network. A centralized stor-age repository that provides physical security in an environmentally regulated location. The data in a SAN can be easily managed (i.e., backed up regularly, etc.) and is protected from equipment, software, and procedural failures.
