Network World - Network security problems are part of daily IT life these days. There are myriad issues, from patching Windows machines to stopping worms and protecting your assets from nasty insider threats. Here’s a round up of the hottest recent network security news.
Is it possible that given a clean slate and likely millions of dollars, engineers could come up with the ultimate in secure network technology? The scientists at the Defense Advanced Research Projects Agency (DARPA) think so and this week announced the Clean‐Slate Design of Resilient, Adaptive, Secure Hosts (CRASH) program that looks to lean heavily on human biology to develop super-smart, highly adaptive, supremely secure networks.
Researchers at Pennsylvania State University say they can block the spread of self-propagating worms on corporate networks while keeping infected machines online so they can continue performing their legitimate duties.
While it is the same in many public and private corporations, government cloud computing projects can be a double-edged sword: while cloud computing offers many benefits, it can also create numerous information security risks. That was the bottom line from a report issued today by the watchdogs at the Government Accountability Office that stated until rules that specifically address information security for cloud computing are developed, federal agencies may be hesitant to implement cloud computing, and those programs that have been implemented may not have effective information security controls in place placing information at risk.
Most corporate networks lack serious oversight, that is, no one is really watching. Watching the network and computer systems is expensive, overwhelming and fraught with false positives. No wonder then that insider attacks go undetected for months, malware proliferates stealthily and hackers can spend their time gradually infiltrating deeper and deeper, undetected. It's simply too hard to discern between legitimate activities and illegitimate or malicious activities. Without context, wading in the enormous volume of logs or network traffic leads to information overload. How to tell who's up to no good? Well, you shall know them by their deeds.
Three out of four companies will soon face more security risks because they continue to run the soon-to-be-retired Windows XP Service Pack 2 (SP2), a report published recently claimed. According to Toronto, Canada-based technology provider Softchoice, 77% of the organizations it surveyed are running Windows XP SP2 on 10% or more of their PCs. Nearly 46% of the 280,000 business computers Softchoice analyzed rely on the aged operating system.
Despite the fact that network access control hasn't yet lived up to its initial promise, network access control is very much alive, as evidenced by the fact that 12 vendors participated in our network access control test, including industry leaders Microsoft, HP, Juniper, McAfee, Symantec and Alcatel-Lucent.
Security is the No.1 priority for corporate networking executives, which means staying on top of the broad range of technologies used to fulfill the predominant model of network protection - defense in depth. Here is a quiz that draws questions from the vast spectrum of security options, including authentication, cryptograpy, firewalls, VPNs and more. Keep track of your score and see how well you do at the end.
It's not a very good day when a security report concludes: Disruptive cyber activities expected to become the norm in future political and military conflicts. But such was the case today as the Government Accountability Office today took yet another critical look at the US federal security systems and found most of them lacking.
Non-traditional communications devices such as smartphones and game consoles pose a particular problem to law enforcement agencies trying to milk them for forensic data that reveals criminal activity, attendees were told at the 2010 Computer Forensics Show in New York City.
The FBI and its Internet Crime Complaint Center (IC3) today said they are seeing an uptick in the complaints about online scammers trying to steal your money posing as a good friend left stranded somewhere in need of quick cash.
Despite how attractive cloud computing can sound as an outsourcing option, there's widespread concern that it presents a security and legal minefield for businesses and government. Cloud service providers often cultivate an aura of secrecy about data centers and operations, claiming this stance improves their security even if it leaves everyone else in the dark.
When it comes to our nation's information systems and cyber infrastructures, the hackers never stop trying to smash it and the government should never stop trying to protect it. But while threats to information systems are evolving, federal information systems in particular are not keeping up to consistently thwart threats.
Most organizations have been the target of an advanced threat, according to results of a study released this week by Ponemon Institute and sponsored by NetWitness. The research includes the responses of 591 IT and IT security practitioners and found 83% believe their organization has been the target of an advanced threat, with 71% reporting an increase in advanced threats over the past 12 months. The majority of those polled, 70%, said that advanced threats suggest a new, more dangerous threat landscape.
