Old Timer IT Terms That You should Never Use: Stay Cool!

"I don't need a cloak to become invisible, Harry."

Do you know, or can you name, the one referred to as 'Dumbledore', in your office? No! Then I guess it's probably you!

If you’re old enough to remember the rise of silicon based technology, then you may need a refresher course when it comes to talking about "today's" technology.

Techie Term Checklist
You have here a short list of outdated techie terms, phrases that you shouldn’t be using at work anymore because they will make you seem old and a practioner of the ancient 'black' arts. This is especially true if you’re looking for a new job and on the interview trail. You should be talking about "cloud computing," not "ASPs" even though they are basically the same thing.

This list is also useful for you young whipper-snappers too. Now, when your elders and betters in the office use one of these terms, you can still laugh at them but at least you'll know what their talking about.

1. The Intranet

Popular in the mid-90s, the term "intranet" referred to a private network running the Internet Protocol and other Internet standards such as the Hypertext Transfer Protocol (HTTP). It was also used to describe an internal Web site that was hosted behind a firewall and was accessible only to employees. Today, every private network runs IP. So you can just use the term virtual private network or VPN to describe a private IP-based network.

2. Company based Extranets

An "extranet" referred to private network connections based on Internet standards such as IP and HTTP that extended outside an organisation, such as between business partners. Extranets often replaced point-to-point electronic data interchange (EDI) connections that used standards such as X12. Today, companies provide suppliers, resellers and other members of their supply chain with access to their VPNs.

3. Web Surfing

When is the last time you heard someone talk about surfing the Web? You know the term is out of date when your kids don’t know what it means. To teens and tweens, the Internet and the World Wide Web are one and the same thing. So it’s better to use the term "browsing" the Web if you want to be understood. Or you can just say "Google" since everyone uses that term as a verb.

4. Push Technology

The debate over the merits of "push" versus "pull" technology came to a head in 1996 with the release of the PointCast Network, a Web service that sent a steady stream of news to subscribers. However, PointCast and other push technology services required too much network bandwidth. Eventually, push technology evolved into RSS feeds, which remain the preferred method for publishing information to subscribers of the Internet. RSS stands for Really Simple Syndication.

5. Application Service Provider (ASPs)

During this decade, the term "Application Service Provider" evolved into "Software-as-a-Service." Both terms refer to a vendor hosting a software application and providing access to it over the Web. Customers buy the software on a subscription basis, rather than having to own and operate it themselves. ASP was a hot term prior to the dot-com bust. Then it was replaced by "SaaS." Now it’s cool to talk about "cloud computing."

6. Personal Digital Assistant (PDA)

Coined by former Apple CEO John Sculley back in 1992 when he unveiled the Apple Newton, the term "personal digital assistant" referred to a handheld computer. PDA was still in use in 1996, when the Palm Pilot was the hottest handheld in corporate America. Today, the preferred generic term for a handheld like a Blackberry or an iPhone is a "smartphone".

7. Internet Telephony

You need to purge the term "Internet telephony" from your vocabulary and switch to VoIP, for Voice over IP. Even the term VoIP is getting old-fashioned because pretty soon all telephone calls will be routed over the Internet rather than the Public Switched Telephone Network. It’s probably time to stop referring to the PSTN, too, because it is headed for the history books as all voice, data and video traffic is carried on the Internet.

8. Weblog

A blog is a shortened version of "Weblog," a term that emerged in the late 1990s to describe commentary that an individual publishes online. It spawned many words still in use such as "blogger" and "blogosphere." Nowadays, few people have time to blog so they are "microblogging," which is another word that’s heading out the door as people turn Twitter into a generic term for blasting out 140-character observations or opinions.

9. Thin Client

You have to give Larry Ellison credit for seeing many of the flaws in the client/server computing architecture and for popularizing the term "thin client" to refer to Oracle’s alternative terminal-like approach. In 1993, Ellison was touting thin clients as a way for large organizations to improve network security and manageability. Although thin clients never replaced PCs, the concept is similar to "virtual desktops" that are gaining popularity today as a way of supporting mobile workers.

10. World Wide Web

Nobody talks about the "World Wide Web" anymore, or the "Information Superhighway," for that matter. It’s just the Internet. It’s a distinction that Steve Czaban, the popular Fox Sports Radio talk show host, likes to mock when he refers to the "Worldwide Interweb." Nothing dates you more than pulling out one of those old-fashioned ways of referring to the Internet such as "infobahn" or "electronic highway."

Be Aware! Voice and Data Can Be Spied on

Attackers seeking to do harm or mischief to your networks work with an ever expanding arsenal of tools that sometimes seem to be the stuff of spy fiction, but they are all too real.

Here are 10 Spy style cloak-and-dagger ways, legal and illegal, to secretly tap into networks and computers to capture data and conversations.

1. Wireless keyboard eavesdropping: Remote-exploit.org has released an open source hardware design and accompanying software for a device that captures then decrypts signals from wireless keyboards. The device uses a wireless receiver that can be concealed in clothing or disguised as a common object that could be left on a desk near a PC to pick up signals.

Called Keykeriki, the technology targets 27MHz wireless keyboards to exploit insecurities that remote-expoit.org discovered earlier. The company plans to build and sell the hardware.

2. Wired keyboard eavesdropping: Electromagnetic pulses that keyboards make to signal what key is being hit travel through the grounding system of the keyboard and the computer itself as well as the ground for the electrical wiring in the building where the computer is plugged in.

Probes placed on the ground for the electric wiring can pick up these electromagnetic fluctuations, and they can be captured and translated into characters. The potential for this type of eavesdropping has been known for decades, and many experts believe spy agencies have refined techniques that make it practical. Andrea Barisani and Daniele Bianco, researchers for network security consultancy Inverse Path, are presenting their quick-and-dirty research on the topic at this year's Black Hat USA conference in the hopes of sparking more public research of these techniques.

3. Laptop eavesdropping via lasers: Bouncing lasers off laptops and capturing the vibrations made as keys are struck give attackers enough data to deduce what is being typed. Each key makes a unique set of vibrations different from any other. The space bar makes an even more unique set, Barisani and Bianco say.

Language analysis software can help determine which set of vibrations correspond to which key, and if the attacker knows the language being used, the message can be exposed, they say.

4. Commercial keyloggers: Early keyloggers were devices attached in-line with keyboards, but they advanced to software tools that grab keystrokes and store or send them to an attack server. Commercial versions have the software loaded on memory sticks that can dump the software on a computer and then be reinserted later to download the collected data.

5. Cell phones as remotely activated bugs: Software loaded onto certain models of cell phones can silence the ringers and cut off the light displays that would normally be triggered when calls are made to them. The caller can then listen in on conversations in the room where the phone is located.

According to press reports, the FBI received court permission to use this technique to spy on suspected Mafia members in New York.

6. Cell phone SIM card compromise: If attackers can get possession of a cell phone briefly, they can use commercially available software to download and read SIM cards and their store of phone numbers, call logs, SMS messages, photos and so on.

For instance PhoneFile Pro is software on a USB stick that claims to enable both the download and the display of the data.

7. Law enforcement wiretapping based on voice print: Phone company voice switches include software that can search all conversations going through it for voices that match sets of voiceprints. Whenever the switch makes a match, it can trigger a recording of the conversation and alert law enforcement officials, says James Atkinson, an expert in technical surveillance countermeasures.

The feature is designed to support communications assistance for law enforcement (CALEA) -- the law that requires phone companies to provide wiretapping access under court order to specific communications traffic.

8. Remote capture of computer data: Under a sketchy technique called Computer and Internet Protocol Address Verifier (CIPAV), the FBI has remotely tracked down data about individual computers.

Details of the technology have never been publicly revealed, but they were used to track down high-school students who sent e-mail bomb threats. CIPAV grabs IP and MAC addresses, running processes, visited Web sites, versions of operating systems, registered owner and logging of computers the target computers connect to. It is believed the software that does this is dropped in via exploiting instant messaging.

9. Cable TV as an exploitable network: Because most cable TV networks are essentially hubbed, any node can monitor any other node's traffic, says James Atkinson, an expert in technical surveillance countermeasures. By and large security is rudimentary and the encryption used could be hacked by someone with basic technical skills and readily available decryption tools, he says.

10. Cell phone monitoring: Commercially available software claims to capture cell phone conversations and texting. Attackers need to get physical access to the phone to upload the software that enables this.

There are several commercial brands on the market, but there are also online complaints that the software doesn't work as advertised or is more complicated to use than the vendors let on.

Skype is Declared a Security Risk to Russia: Putin put out

MOSCOW (Reuters) - Russia's most powerful business lobby moved to clamp down on Skype and its peers this week, telling lawmakers that the Internet phone services are a threat to Russian businesses and to national security.

Vladimir Putin v Skype
In partnership with Prime Minister Vladimir Putin's political party, the lobby created a working group to draft legal safeguards against what they said were the risks of Skype and other Voice over Internet Protocol (VoIP) telephone services.

Voice Over IP
VoIP software has used the Internet to let hundreds of millions of people talk long-distance for free, or at far cheaper rates than traditional service providers can offer.

Foreign Entities Encroaching
At a meeting of the lobby this week, telecom executives portrayed the most popular VoIP programmes like Skype and Icq as encroaching foreign entities that the government must control.

Government Restrictions
"Without government restrictions, IP telephony causes certain concerns about security," the lobby's press release said. "Most of the service operators working in Russia, such as Skype and Icq, are foreign. It is therefore necessary to protect the native companies in this sector and so forth."

Skype's Response - Busy!
A spokesperson for Skype was not immediately available for comment.
