Symantec Delivers Groundbreaking Reputation-based Security Technology
New technology
codenamed “Quorum” leverages the wisdom of crowds
to
deliver an entirely new approach to protecting against new
and unknown threats
Symantec Corp. (Nasdaq: SYMC) today announced that it has integrated its revolutionary reputation-based security technology, Quorum, into its new Norton 2010 solutions: Norton Internet Security 2010 and Norton AntiVirus 2010. Quorum leverages the anonymous software usage patterns of Symantec’s extensive volunteer user community to automatically identify entirely new spyware, viruses and worms.
“This new technology changes the rules of the malware game, shifting the odds significantly in favor of our users,” said Stephen Trilling, senior vice president, Security Technology and Response, Symantec. “By harnessing the wisdom of our tens of millions of users, we’re able to detect threats that are invisible to traditional security products.”
Why
Reputation-Based Security Technology?
Significant changes
in the threat landscape over the last few years have
dramatically altered the typical distribution profile for
new malware. Today, instead of a single malware strain
infecting millions of machines, it is much more common to
see many millions of malware strains, each targeting only a
handful of machines. In 2008, Symantec discovered more than
120 million distinct malware variants. In this environment,
it is necessary to move beyond traditional security
approaches to stay ahead of new malware.
Traditional antivirus software relies on virus signatures to blacklist those pieces of malware that should be blocked from a user’s machine. Ten years ago, Symantec published an average of five new virus signatures each day. Today, in spite of the fact that each signature can detect many different malware strains, security vendors regularly publish thousands of signatures or more per day.
Quorum reputation-based security complements traditional security techniques by using anonymous software usage patterns to classify files as safe or unsafe. The Quorum technology was developed at Symantec from the ground up and provides a fundamentally new layer of protection from today’s latest threats. Symantec Research Labs began development of the technology about three years ago, investigating how small amounts of data regarding file usage on a user’s system, collected from a very large distributed community, could be used to predict the likelihood of a given file being malicious or not. After a successful prototype was developed, the project was transferred to the Security Technology and Response group to develop a full commercial release and bring the new technology to market.
How does
it work?
Symantec’s Quorum reputation-based security
leverages data from multiple sources, including: anonymous
data contributed by tens of millions of Norton Community
Watch members, data provided by software publishers and
anonymous data contributed by enterprise customers in a data
collection program tailored to large enterprises. The data
is continually imported and fed into the reputation engine
to produce a security reputation rating for each software
file, all without ever having to scan the file itself.
Quorum uses information such as the file’s prevalence, age
and other attributes to compute highly accurate reputation
scores. These reputation ratings are then made available to
all Symantec users through a large cloud-based
infrastructure of Symantec servers. For more detailed
information on Quorum, visit the Norton Protection
Blog.
What are the benefits of Quorum?
Provides information on all executable files. Traditionally, security companies primarily have protection for the malware actually sent to them by vigilant users or exchanged with other security researchers. In contrast, Quorum holds reputation ratings on every executable file used by every participating Symantec user across the globe.
Integrates with Symantec’s new Download Insight. The most visible way to see Quorum in action in Norton Internet Security 2010 and Norton AntiVirus 2010 is to download a new executable file from the internet. The new Download Insight feature uses Quorum reputation information to help determine each downloaded file’s safety – the user is then informed of the file’s reputation and bad-reputation files are automatically blocked. In addition, a user can right-click on any executable file and find out where the file came from, how many other Symantec users are using the file, when Symantec first saw the file and what the security reputation is for the file.
Reduces dependence on traditional signatures. Quorum defeats an attacker’s ability to mutate their malware to evade traditional signature-based detection. In fact, with Quorum, the more an attacker modifies a threat the more obvious it will be that the file is suspicious.
Amplifies existing security technologies.
In addition to providing an additional layer of protection,
Quorum also allows existing Symantec security technologies,
including heuristics and behavior-based detection, to be
deployed in a more aggressive mode to increase the overall
level of protection provided to users.
