Why Should Security Software Take Over Your PC?

I'm really encouraged by hearing that Zsecurity internet security software promises anti virus protection, antispyware defense and other benefits -- without using so many of my computer's own resourses to do it.

I've become frustrated as my big brand-name computer security software slows down everything that I do. It just doesn't seem right that something like anti-virus protection should negatively impact me so much.

Computer performance is one of the benefits that Z security software promises as an advantage over those other better-known security packages.

Click on the links above to learn more, and for a free trial of the Z security software. You can try it for yourself to see if you see performance or other advantages over your other security solution.

Win-Win With Active Directory Management

Right now, businesses all over -- large and small -- are working to do more with less. Information technology is a great enabler to make that happen.

That's the goal behind Ensim's business solutions, such as Active Directory Management, Exchange Management and the provision of tools like Active Directory Tools.

Ensim's solutions involve further automating IT functions such as the provision of services, cutting down business overhead. It also aims to improve security by allowing users access to only the appropriate system resources.

IT was the great enabler that propelled growth in the go-go 1990s. Today, we have the technology but what we need is more economic growth. New, innovative solutions such as those offered by Ensim can help make that happen.

Researchers Create Next-Generation Software Aimed At Defending Cyber Attack

Researchers at George Mason University’s Center for Secure Information Systems have developed new software that can reduce the impact of cyber attacks by identifying the possible vulnerability paths through an organization’s networks.

By their very nature networks are highly interdependent and each machine’s overall susceptibility to attack depends on the vulnerabilities of the other machines in the network. Attackers can take advantage of multiple vulnerabilities in unexpected ways, allowing them to incrementally penetrate a network and compromise critical systems. In order to protect an organization’s networks, it is necessary to understand not only individual system vulnerabilities, but also their interdependencies.

“Currently, network administrators must rely on labor-intensive processes for tracking network configurations and vulnerabilities, which requires a great deal of expertise and is error prone because of the complexity, volume and frequent changes in security data and network configurations,” says Sushil Jajodia, university professor and director of the Center for Secure Information Systems. “This new software is an automated tool that can analyze and visualize vulnerabilities and attack paths, encouraging ‘what-if analysis’.”

The software developed at Mason, CAULDRON, allows for the transformation of raw security data into roadmaps that allow users to proactively prepare for attacks, manage vulnerability risks and have real-time situational awareness. CAULDRON provides informed risk analysis, analyzes vulnerability dependencies and shows all possible attack paths into a network. In this way, it accounts for sophisticated attack strategies that may penetrate an organization’s layered defenses.

CAULDRON’s intelligent analysis engine reasons through attack dependencies, producing a map of all vulnerability paths that are then organized as an attack graph that conveys the impact of combined vulnerabilities on overall security. To manage attack graph complexity, CAULDRON includes hierarchical graph visualizations with high-level overviews and detail drilldown, allowing users to navigate into a selected part of the big picture to get more information.

“One example of this software in use is at the Federal Aviation Administration. They recently installed CAULDRON in their Cyber Security Incident Response Center and it is helping them prioritize security problems, reveal unseen attack paths and protect across large numbers of attack paths,” says Jajodia. “While currently being used by the FAA and defense community, the software is applicable in almost any industry or organization with a network and resources they want to keep protected, such as banking or education.”

Funding for this software development was provided by the defense, homeland security and intelligence communities and the FAA. Researchers in the Center for Secure Information Systems involved in the software development include Jajodia; Steven Noel, associate director; and Pramod Kalapa, senior research scientist. Five patents are currently pending on the CAULDRON software.

2007 Computer Crime Survey Shows Losses Jumping After 5-Year Decline

The average annual loss reported by U.S. companies in the 2007 CSI Computer Crime and Security Survey more than doubled, from $168,000 in last year's report to $350,424 in this year's survey, according to the The Computer Security Institute (CSI). This ends a five-year run of lower reported losses.

Financial fraud overtook virus attacks as the source of the greatest financial loss. Virus losses, which had been the leading cause of loss for seven straight years, fell to second place. Another significant cause of loss was system penetration by outsiders.

Additional key findings include:

-- Almost one-fifth of those respondents who suffered one or more kinds of security incident say they'd suffered a "targeted attack," i.e. a malware attack aimed exclusively at their organization or at organizations within a small subset of the general population.

-- Insider abuse of network access or e-mail (such as trafficking in pornography or pirated software) edged out virus incidents as the most prevalent security problem, with 59% and 52% of respondents reporting each respectively.

-- When asked generally whether they'd suffered a security incident, 46% of respondents say yes, down from 53% last year and 56% the year before.

"At a period when experts throughout the industry have been discussing with concern the growing sophistication and stealth of cyber attacks, here we have a couple hundred respondents saying they lost significantly more money last year," says Robert Richardson, CSI director and author of the survey. "There's a strong suggestion in this year's results that mounting threats are beginning to materialize as mounting losses."
