IBM Vs Microsoft in tech giants ranking...!!!

For the first time since 1996 IBM's market value has exceeded Microsoft's.

IBM's closing price on 29 September was $214bn (£137.4bn) while Microsoft's was a shade behind at $213.2bn (£136.8bn).

The values cap a sustained period in which IBM's share price has moved steadily upward as Microsoft's has generally been in decline.

The growth means IBM is now the second largest technology company by market value. Apple still holds the top slot with a value of $362bn (£232bn).

Since the beginning of 2011, IBM's share price has made steady gains & is now 22% higher than at the start of the year, according to Bloomberg figures. By contrast, Microsoft's value has dropped 8.8% over the same time period.

Analysts put the switch in the number two slot down to a decision IBM made in 2005 to sell off its PC business to Chinese manufacturer Lenovo to concentrate on software & services.

"IBM went beyond technology," Ted Schadler, a Forrester Research analyst told Bloomberg. "They were early to recognise that computing was moving way beyond these boxes on our desks."

By contrast much of Microsoft's revenue comes from sales of Windows & Office software used on PCs. Also, Microsoft is between releases of Windows which can mean a fallow period for its revenues.

Windows 7 was released in 2009 & Windows 8 is not expected to be released until late 2012 at the earliest.

Many have also claimed that the rise of the web, mobile computing & tablets spells the end of the PC era. In early August, Dr Mark Dean, one of the designers of the original IBM PC, declared that the centre of the computing world had shifted away from the humble desktop.

Bad spelling opens up security loopholes...

Facebook has paid $5000 to those who found the biggest security holes in its site. & has spent $40,000 (£25,000) in the first 21 days of a program that rewards the discovery of security bugs.

The bug bounty program aims to encourage security researchers to help harden Facebook against attack.

One security researcher has been rewarded with more than $7,000 for finding six serious bugs in the social networking site.

The program runs alongside Facebook's efforts to police the code it creates that keeps the social site running.

A blog post by Facebook chief security officer Joe Sullivan revealed some information about the early days of the bug bounty program.

He said the program had made Facebook more secure by introducing the networking site to "novel attack vectors, & helping us improve lots of corners in our code".

The minimum amount paid for a bug is $500, said Mr Sullivan, up to a maximum of $5000 for the most serious loopholes. The maximum bounty has already been paid once, he said.

Many cyber criminals & vandals have targeted Facebook in many different ways to extract useful information from people, promote spam or fake goods.

It's hardly surprising that the service is riddled with rogue apps & viral scams”

Graham Cluley Sophos

Mr Sullivan said Facebook had internal bug-hunting teams, used external auditors to vet its code & ran "bug-a-thons" to hunt out mistakes but it regularly received reports about glitches from independent security researchers.

Facebook set up a system to handle these reports in 2010 which promised not to take legal action against those that find bugs & gave it chance to assess them.

Paying those that report problems was the logical next step for the disclosure system, he said.

Graham Cluley, senior technology consultant at Sophos, said many other firms, including Google & Mozilla, run similar schemes that have proved useful in rooting out bugs.

However, he said, many criminally-minded bug spotters might get more for what they find if they sell the knowledge on an underground market.

He added that the bug bounty scheme might be missing the biggest source of security problems on Facebook.

"They're specifically not going to reward people for identifying rogue third party Facebook apps, clickjacking scams & the like," he said. "It's those sorts of problems which are much more commonly encountered by Facebook users & have arguably impacted more people."

Facebook should consider setting up a "walled garden" that only allowed vetted applications from approved developers to connect to the social networking site, he said.

"Facebook claims there are over one million developers on the Facebook platform, so it's hardly surprising that the service is riddled with rogue apps & viral scams," he said.

Facebook will check every links for viruses

Facebook will check every web link its users click on for computer viruses & other dangers as part of efforts to improve the security of the world's largest social network.

From today, hundreds of millions of outbound links every day will be passed through a system provided by the web security firm Websense.

It will effectively visit pages on users' behalf, & apply a series of tests for Trojans, phishing attempts, botnets & other threats.

If the system does not detect a problem with a link, the user will be allowed to visit the page as normal, without any sign that it has been checked. When a threat is detected, however, Facebook will present a warning with links to more information. If the user wants to proceed anyway, they will be allowed.

"Facebook is a big target for criminals online," said Spencer Parker of Websense.

"We'll be protecting all 750 million of its users."

To add phishing safety net, Facebook works with Websense

Users will see this notice if they are about to visit a potentially harmful website, giving them the option to go back to the previous page.

Facebook have stepped up their battle against phishing & malware scammers by partnering with security firm Websense.

As of next week, users will be warned if they are about to be taken to a malicious website.

The social network has suffered to date as many of its 700 million users unwittingly click on dangerous links supposedly posted by their friends.

Such attacks usually trick users into sharing passwords or data.

Facebook already tells users if they are about to visit an external site, but the current set up makes no distinction between friendly & dangerous sites.

The new technology will present a warning screen whenever it suspects a page poses a threat to the users, giving details of the risk.

From here, users are encouraged to return to the previous page.

If they wish, users can continue to the intended page, albeit very much at their own risk.
'Profitable target'

Both Facebook & Websense will hope the extra measures will be enough to deter potential scammers from focusing their efforts on the network.

Scams regularly catch out hundreds of thousands of users at a time.

As more of these 'friend in the middle' attacks happen, you start to trust your friends less.”

Spencer Parker Websense

"There's over 700 million users on Facebook," Websense's Spencer Parker told the BBC.


"As a piece of real estate, it's extremely profitable to be targeted by malware writers."


The protection will be powered by Websense's "Threatseeker Cloud", a system which stores a database of known malicious URLs.


The system can also detect unknown dangerous URLs by assessing threats in real-time.


This means harmful URLs can be blocked even before they are known to the company - cutting off a key tactic used by phishers in which constantly changing URLs fool database-driven protection.


In addition, the system will "follow" links made using popular URL shorteners - such as bit.ly & ow.ly - to verify their safety.

Due to the nature of how we interact with our friends, Mr Parker says phishing attacks on Facebook are much harder to prevent than other commonly used techniques.

"One of the things with Facebook, of course, is that you have that element of trust in a social network. If one of your friends posts something, you automatically trust it more than if it just received as a spam email.
