Traditional Anti-Virus Can’t Meet New Threats

Posted on October 19, 2004December 30, 2021 by admini

“The need for security is expanding beyond the PC,” wrote Jonathan Singer, an analyst with the Yankee Group, in an e-mail to TechWeb. “Mobile devices such as smart phones and PDAs, which are often used for business purposes without security integration, are opening new avenues for malicious code,” he added.

Early efforts by hacker to engage these devices were relegated to using them as entry points for viruses and worms delivered via e-mail, but as networked handhelds proliferate, tactics have changed. As other devices become networked–such as printers and copiers–and as voice over IP (VoIP) hardware grows in popularity, they’ll be targeted too, or used to launch additional attacks.

“Look for these types of attacks to become pervasive in the next 12 to 24 months,” Singer said.

Behavioral-based anti-virus protection doesn’t rely on one-to-one signatures to match against known malicious code, but examines possible malware for characteristics common to viruses and worms. Among their advantages are a theoretical ability to recognize unknown viruses–thus providing a defense against so-called “zero-day” attacks–less frequent updating, and smaller size.

“In the next two to four years, anti-virus software will migrate from signature recognition to a hybrid of signatures and behavioral recognition,” predicted Singer.

Enterprises should set policies on PDA and smartphone use, said Singer, to protect the network first, make handhelds productive second.

New ways of measuring security

Posted on October 19, 2004December 30, 2021 by admini

Officials at Addamark Technologies Inc. are delving deeper into the security information management arena with a revamped product and a new name, SenSage Inc.

Before refocusing, SenSage served as a repository for forensic analysis instead of gathering data in real-time like most security information management products, said Jim Pflaging, the company’s chief executive officer. For instance, someone within an agency who has valid access might be performing suspicious activities, or the systems administrator with privileges to many systems might create bogus accounts.

Meanwhile, officials at netForensics Inc. have released the nFX Open Security Platform, which supports the nFX framework, to help agency officials quickly identify and prioritize security issues to reduce threats and risks. Enhancements to the platform include greater fault-tolerance capability, custom agent software development and policy compliance integration.

New advanced threat visualization and analytics capabilities combine the visual tools with reporting and analytics so a security team can identify threats faster.

Feds Eye Larger Security Role for Private Sector

Posted on October 18, 2004December 30, 2021 by admini

A plan is under way in the ever-evolving National Cyber Security Division of the DHS to extend the tenure of Andy Purdy, the group’s interim chief, and augment the position with a part-time outside consultant with direct ties to the private sector. The move, observers say, would enable the division to tackle head-on such prevalent issues as security vulnerability.

The effort is the result of a power vacuum created when Amit Yoran resigned last month as NCSD director. Subsequently, Purdy, one of Yoran’s deputies, was appointed interim director of the NCSD. It now appears that top DHS officials are content to leave him in that position for now and, contrary to early reports, are in no hurry to find a permanent replacement for Yoran.

Purdy, a longtime veteran of federal government service, is known for his ability to work inside the Beltway and get things done—a skill vital to moving the National Strategy to Secure Cyberspace forward, insiders say.

“That is a solid move,” said Alan Paller, director of research at The SANS Institute, based in Bethesda, Md. “They wouldn’t have done that if they were going to bring in someone else right away.”

But Purdy will not be going it alone. Howard Schmidt, former chairman of the now-defunct President’s Critical Infrastructure Protection Board and now chief security officer at eBay Inc., is working with US-CERT as a consultant to the DHS and will be advising Purdy and others.

Schmidt, who also served as Microsoft Corp.’s chief security officer and is a former federal agent, is among the more respected members of the security community, both inside Washington and in the private sector. His involvement with the DHS will be indirect and on a part-time basis, but his presence gives the department a trusted conduit into the private sector, a necessity to implement its strategy.

One area where cooperation with the private sector is key is in the effort to reduce vulnerabilities.

‘Swiss army knife’ software tools not right for patching specific IT problems

Posted on October 16, 2004December 30, 2021 by admini

Security firm Symantec revealed that it documented over a six-month period almost 4,500 new Windows viruses and worms, more than 4.5 times the number recorded during the first six months of 2003.

PatchLink, which provides solutions it says can help businesses to patch vulnerabilities before hackers can take advantage of security holes, is one of the many companies providing patch management options. PatchLink’s Internet-based solution not only scans networks for security holes and then closes them, but also works with all Microsoft, UNIX/Linux, Novell NetWare, and Mac OS X operating systems.

Because every space station has its own set of PatchLink servers, the task of patching all of the servers isn’t left in the hands of a single person but is instead placed into the hands of numerous persons at the various offices.

The “Swiss army knife” approach to addressing problems, he added, won’t cut it. “There are Swiss army knives and there are tools for specific jobs,” he said, explaining that if businesses don’t have the right patch management systems in place, they could end up with compromised systems that would cost them large sums of money to fix. Effective patch management means testing patches and delivering them securely” added Chris Andrew, vice-president of product management at PatchLink.

If a big vulnerability hits, he continued, businesses that get their patches from vendors such as Microsoft may be left depending on solutions providers that are themselves adversely impacted by the vulnerability.

Enterprise security is worst ever, experts say

Posted on October 16, 2004December 30, 2021 by admini

“Enterprises are more exposed than a year ago.The hackers have won!” said Eli Barkat, managing director of venture capital firm BRM Capital, who has been involved in investing in security firms. Barkat cited a lack of innovation in the security industry as why the situation has not improved.

Mike Dalton, president of McAfee in Europe, the Middle East, and Africa, agreed that the security situation is dire, but said that innovation was not necessarily the roadblock. A major problem is a lack of integration in security products, he said.

And while all the experts predicted further consolidations among security companies, that will not necessarily lead to more comprehensive, integrated products, they said. “Today the security business is very diverse and very complex,” said Phillip Dunkelberger, president and CEO of encryption company PGP. “You have four or five different point solutions and they don’t all work together.”

Yanki Margalit, president and CEO of digital rights management provider Aladdin Knowledge Systems, agreed that enterprises are more exposed than ever, but did not put the blame squarely on security companies’ shoulders. There are so many threats,” Margalit said. Part of the remedy would be widely available tools that help developers check the security of the applications they are building, commented Barkat, adding that he hopes Microsoft takes a leading role.

On the subject of the software giant, the experts were divided on the work the company is presently doing on the security front. “Microsoft is clearly not doing a good job at security. Most people in this room who work in security have their jobs because of Microsoft,” Dalton said. They did a horrible, terrible job (in the past) but now they are serious. I believe that they will be a very strong security player and force the rest of the industry to be niche players,” Margalit said.

While the speakers gave no clear direction on the path the industry needs to take to truly alleviate companies’ security woes, they did have some words of advice.

Invest in integrated security products and avoid security appliances whose architecture changes after a few years, Barkat said.

Forget about white lists, which normally refers to a list of e-mail address from which you agree to get mail, thinking they are safe.

You will fail if you try to define everything you can do, Margalit said.

“We need to get out of the defense mode and allow companies to go on the offensive,” Dunkelberger said.

Despite the various opinions, on one point at least everyone seemed to agree. “The existing security situation sucks,” Barkat said, to resounding nods from attendees.

Are Hackers Now Gunning for the Mac?

Posted on October 15, 2004December 30, 2021 by admini

Most of the fixes in this group blocked possible denial-of-service problems that are, to date, theoretical. For example, one addresses vulnerability in a Unix printing system that might expose passwords to hackers, in uncommon situations.

Since the last Mac OS X security update was the third in a month, and because some of the holes looked ripe for exploiting, I have to wonder whether the Mac is now attracting more unwanted attention from hackers.

According to Tim Bajarin, principal analyst with research firm Creative Strategies and a longtime Apple watcher, “The vulnerabilities unfortunately are inherent in the Unix world, and Apple’s choice to build OS X on a Unix foundation brings with it this risk. In that sense, they have gone to school on Microsoft’s problems in this space and are making sure they leave no stone unturned in their quest to keep the OS as secure as possible.”

“At the same time,” Bajarin continues, “the media attention about Apple’s OS being secure has clearly tweaked the interest of hackers, but as of now we have not seen any serious effort by the hacking community to deliberately expose any holes or attack the OS. The vast majority of the fixes in Mac OS X security updates are in response to potential exploits, not actual exploits.”

“And many of the fixes in typical Mac OS X security updates aren’t Mac-specific,” Gruber says, “but rather are updates to open-source components and tools.

Most typical Mac users still have little to fear from the miscreants we Windows users have to vigilantly guard against.
