Why Corporate Networks Are Vulnerable To Virus / Spyware

Thursday, July 14th, 2011

The biggest mistake is to ignore network share access rights – responsible for 35% of incidents. In such a case there might be open sharing with access rights configured as “full access” to everyone on an internal file server or end-user work desktop, e.g., a shared public document workspace where all documents are stored. Sooner or later this can become a prominent source of malware redistribution throughout the organization.

Modern malware takes advantage of existing vulnerabilities. A network with just a single missing patch can be put at serious risk. And this is a common issue seen mostly in small to medium organizations with end-users numbering less than 100. These organizations either do not have enough expertise or ignore patching completely. This mistake is responsible for 25% of incidents.

Use of multiple vendor antimalware solutions (15% of incidents) may lead to a situation where it is hard to mitigate malware attacks. This may occur if one of the vendors does not respond fast enough to attacks. Delays in responses may run to days, weeks or even months. During this time the solution of another vendor would detect and remove malware, but only in its part of the network – and malware would attack it from the unprotected side.

A partially protected environment (15% of incidents) is where an antimalware solution is installed on part of the network, leaving other resources unprotected.

Firmware vulnerability (5% of incidents) may be exploited by attackers through hardware devices, such as routers, firewalls and other network appliances.

And another relatively infrequent mistake (also 5% of incidents) is to believe that software downloaded from the Web is always perfectly sound software.

It’s important that your IT vendor understands these risks and implements solutions to minimize them.  Call us today and we will evaluate your current network setup to minimize your risk of being attacked.

BlackBerry not receiving email?

Wednesday, December 23rd, 2009

Research in Motion on Tuesday night confirmed a BlackBerry outage affecting some users in North and South America – the company’s second in several days.
The problems do not appear to affect calling or text messaging, but users are not receiving e-mails. Others have reported problems with BlackBerry Messenger (BBM), an instant message program available on the devices.
“Some BlackBerry customers in the Americas are experiencing delays in message delivery,” RIM said in a statement. “Technical teams are actively working to resolve the issue for those impacted. RIM apologizes for any inconvenience experienced by customers.”
The outage is the second for RIM in that past five days. For several hours on Thursday, users were once again not able to receive or send e-mail messages.

Windows7 is a winner!

Monday, October 19th, 2009

After conducting an analysis of actual inventory data collected from more than 450,000 corporate PCs between November 2008 and August 2009, Softchoice (via ComputerWorld) has concluded that 88 percent of them meet the minimum system requirements to run Windows 7. The sample consisted of 248 individual organizations representing a wide range of industries from across the United States and Canada, including financial, health care, manufacturing, and education. In comparison, when Windows Vista was going to be released, Softchoice found that only 50 percent of corporate PCs were able to support the minimum system requirements.
