SAN FRANCISCO – The new generation of Operating Systems includes improvements aimed at keeping data safer. Microsoft, long the target of hackers’ efforts and resulting customer ire, has promised anti-spyware and other tools in the upcoming version of Windows, code-named Longhorn. And while they aren’t as aggressive about marketing their security efforts, Apple Computer and Linux-seller Novell recently released updates with an eye to stronger defenses.

That doesn’t mean companies aren’t still serving up other advances, such as smoother collaboration or more-comprehensive search. But given home PC owners’ growing worries about security, OS makers are aiming to prove they are trying harder to prevent software vulnerabilities and protect against outside attacks, CNET. Com reported.

“The OS makers know that their futures depend on the trust that buyers have with their products, and buyers aren’t trusting computers today,” Forrester Research analyst Ted Schadler said. “We know that people are downloading less music, shopping online less and steering away from online banking because of security fears.”

Several high-profile incidents of data theft, such as the ChoicePoint breach, have highlighted the need to protect confidential personal information. Alerts about phishing and other online fraud schemes have further publicized the risks. On top of this, malicious code writers have not let up on sending out traditional PC viruses.

Even though these consumer security threats sometimes take advantage of weak points in technologies other than operating systems, or exploit people’s habits, OS makers often bear the brunt of the blame for them, Schadler said.

“(Security) is a problem that consumers are increasingly aware of and angry about, and they want to blame someone,” he said. “The OS players are taking notice because they have to.”

Some of the planned security tools in Longhorn, whose delayed launch is now scheduled for 2006, are likely to put Microsoft in competition with third-party security software vendors such as Symantec. However, Symantec and others have said they remain unthreatened by Microsoft’s development of onboard antivirus measures and anti-spyware.

At Apple, security may not be the primary thrust of its introduction of Mac OS 10.4 Tiger, but the company said it is more focused on helping consumers protect their computers than it has ever been before.

The main security concept in designing Tiger, released at the end of April, was to let people see more clearly every program running on their computer, according to Apple executives. That visibility should make it harder for malicious programs to install themselves or hide in documents or Web pages that may appear to be harmless, they said.
