Tough local laws drive corporate security

Posted on January 25, 2005December 30, 2021 by admini

Michael Colao, director of information management at merchant bank Dresdner Kleinwort Wasserstein, says this has little to do with bolstering information security and everything to do with ensuring there is no risk of senior managers going to jail.

Failure to apply with tighter compliance laws can result in criminal sanctions. Breaches to Italy’s rigorous data security and privacy laws, for example, are punishable by up to three years imprisonment regardless of whether an information security breach has taken place. So far, Italian authorities have not served any notable enforcement action against data slackers. But some multinationals are taking no chances: Microsoft, for example has revised its global policy to apply with Italian regulations, according to Colao, speaking yesterday at the Computer and Internet Crime Conference in London.

California’s security breach disclosure law obliges companies to notify their customers of security breaches exposing personal information, such as social security numbers, applies only to the state. But US banks are beginning to use it as a model for their national policy.

Although the most security conscious organisations are applying the most restrictive policies nationally or internationally other firms remains apathetic about establishing a security policy of any description. According to Calao, tighter rules could could perversely create a wider gap between the security-conscious and the apathetic, with some IT directors simply burying their heads in the sand.

Londoners top world in leaving laptops in taxis

Posted on January 25, 2005December 30, 2021 by admini

The international survey of 900 taxi drivers reveals that absent minded passengers are leaving sensitive information up for grabs because they fail to use password and encryption facilities on mobile devices.

In the last six months in London, 63,135 mobile phones (an average of three phones per taxi), 5,838 PDAs and 4,973 laptops have been left in licensed taxi cabs. Cab drivers in Helsinki, Oslo, Munich, Paris, Stockholm, Copenhagen, Chicago and Sydney also took part in the study which revealed wide international differences.

Londoners left more than double the number of laptops in the back of taxis compared with other cities. In Chicago, the mobile device most likely to be left behind were PDAs, with one taxi driver reporting finding 40 in his taxi in the past six months.

Danes were most forgetful when it came to mobile phones, leaving seven times as many in the back of cabs as Germans or their Swedish neighbours.

The survey in London was conducted by TAXI, the magazine for the Licensed Taxi Drivers Association magazine, and sponsored by Pointsec, a mobile security outfit. Pointsec carried out a similar study in London three and a half years ago and recorded 71 per cent fewer PCs left in the back of cabs. Magnus Ahlberg MD of Pointsec commented “It is alarming to see that the problem of losing mobile devices has accelerated so dramatically since 2001, with more people than ever losing their mobile devices in transit.

In fact, mobile users are in a worse position now, because they are far more reliant on using their mobile devices to store massive amounts of sensitive information, with very few concerned about backing it up or protecting it.”

With such forgetful passengers it’s just as well that taxi drivers are generally an honest bunch. According to the survey, an average of 80 per cent of passengers were reunited with their mobile phones and 96 per cent with their PDAs and laptops – with the cab drivers in almost all cases tracking down their owners. However, the case was very different in Australia, with only 46 per cent of laid-back passengers bothering to reclaim their mobiles and only 18 per cent being reunited with their laptops.

Stuart Pessok, editor of TAXI commented: “Often people are working whilst being driven around in taxis and its common-place for them to forget their mobile devices.

Luckily if they forget them in a taxi, there is a good chance they’ll get them back, but will they be so lucky if they forget them in an airport, restaurant, train or tube?

UK taxi drivers reported finding a “harp, a throne, £100,000 worth of diamonds, 37 milk bottles, a dog, a hamster, a suitcase from the fraud squad and a baby” in their cabs.

Laptop Data At Risk, Vendor’s Study Finds

Posted on January 24, 2005December 30, 2021 by admini

According to the study of about 200 small- and medium-sized business IT managers, 50 percent of those businesses don’t have a formal procedure in place for backing up enterprise data stored on laptops, Imation said in a statement.

“As the workforce becomes increasingly mobile, more and more ‘mission-critical’ information, such as customer records, sales presentations and company financials, is being stored on laptops putting data at potential risk of loss,” Brent Ashton, Imation’s marketing manager for small and mid-sized businesses said in a statement.

About 40 percent of the companies in the survey have what the vendor called an extensive network of laptop computers, but only half of those companies had formalized backup procedures for those laptops, the survey found.

Hackers use old-fashioned eavesdropping to steal data

Posted on January 24, 2005December 30, 2021 by admini

The danger of attacks with insider information was illustrated earlier this month with the arrest of a California man accused of breaking into mobile phone network T-Mobile USA’s database and reading e-mails and files of the U.S. Secret Service, and by the exploits of a hacker who breached a hospital’s database and changed mammogram results.

The nature of threats to network security has changed as sophisticated hackers learned to tap into sensitive information flowing through telecommunications’ servers, especially those that provide wireless and Internet access.

Security experts at Intrusic captured 4,466 passwords and 103 master passwords allowing global access to corporate databases while monitoring one Internet service provider for a 24-hour period, Intrusic President Jonathan Bingham said.

“Telecoms and cable companies are pretty high on the list simply because of their huge customer bases,” Koetzle said. “If they can crack T-Mobile’s database they can get user names and passwords for (millions of) subscribers at all once.” In a statement, T-Mobile, a Deutsche Telekom AG unit, said it “quickly put in safeguards to prevent further access and began an investigation” after a hacker broke into its internal computer systems in 2003 and accessed data on 400 customers.

The key to cutting down on damage from inevitable insider attacks is to constantly monitor data flow and train employees to guard passwords and access to computers, he said. Stan Quintana, director of managed security services at AT&T Corp added that among the “best practices” AT&T advocates is that its customers periodically hack into their own networks.

Flaw found in Office encryption

Posted on January 20, 2005December 30, 2021 by admini

The problem arises because Microsoft programmers did not implement the encryption correctly in its Office applications, Hongjun Wu, a cryptographer at the Institute of Infocomm Research in Singapore, wrote in a paper on the topic.

“A lot of information could be retrieved from those encrypted files,” Wu said in the paper. “If anyone has used the encryption in Microsoft Office…then it is time for him/her to assess the damage that has been caused.”

Microsoft said that it has begun investigating the flaw. “Our early investigation indicates that this issue poses a very low threat for customers,” Microsoft said in a statement sent to CNET News.com. “In some cases, an attacker may be able to read the contents of an encrypted file, if multiple versions of that file are available to the attacker. The attacker would need to have access to two distinct files with the same name that are protected by the same password in order to attempt to exploit the vulnerability.”

In the world of cryptographers, encryption schemes that encode more than one message using the same key are seen as flawed. That’s because a comparison of the information in the encrypted messages can significantly shorten the search for the correct key to unlock the messages.

The Microsoft Office flaw is the latest issue that Microsoft has had with implementing encryption in its products. Security researchers have taken the company to task repeatedly in the past for the weak passwords in previous versions of the Windows operating system. Moreover, the company was at the center of a debate in 1999 on whether the code keys central to Windows NT security were actually secure.

The current issue is almost identical to the weak system key issue in 1999, said Bruce Schneier, chief technology officer of Counterpane Internet Security and author of “Applied Cryptography.” “This is a kindergarten crypto mistake,” Schneier said. “And to make it twice is worse.” Schneier, who wrote about the issue on his blog earlier this week, hammered at Microsoft for not learning from past mistakes. The software maker said that it had not uncovered the newly reported vulnerability in its code reviews, but noted that the flaw appeared similar to a previous flaw.

Microsoft also said it would review the cryptographic code in Office. “Upon completion of this investigation, Microsoft will take the appropriate actions to protect customers, which may include providing a security update through our monthly release process,” the company said.

‘Evil twin’ fear for wireless net

Posted on January 20, 2005December 30, 2021 by admini

Once logged onto an Evil Twin, sensitive data can be intercepted.

“Users need to be wary of using their wi-fi enabled laptops or other portable devices in order to conduct financial transactions or anything that is of a sensitive or personal nature,” said Professor Brian Collins, head of information systems at Cranfield University. “Users can also protect themselves by ensuring that their wi-fi device has its security measures activated,” he added.

BT Openzone, which operates a vast proportion of public hotspots in the UK, told the BBC News website that it made every effort to make its wi-fi secure.

“This means that users’ personal information and data, logon usernames and passwords are protected and secure,” said Mr Clark.

In the vast majority of cases, base stations straight out of the box from the manufacturers are automatically set up with the least secure mode possible, said Dr Nobles.

Cybercriminals who try to glean personal information using the scam, jam connections to a legitimate base station by sending a stronger signal near to the wireless client. “Cybercriminals don’t have to be that clever to carry out such an attack,” said Dr Phil Nobles, a wireless net and cybercrime expert at Cranfield. “Because wireless networks are based on radio signals they can be easily detected by unauthorised users tuning into the same frequency.”

Although wi-fi is increasing in popularity as more people want to use high-speed net on the move, there have been fears over how secure it is.
