Pseudo dynamic memory management in Virtualbox, otherwise know as memory ballooning.September 6th, 2011 by Dan HillAfter looking for a way to dynamically allocate memory in Virtualbox, I discovered it’s not technically possible. With that being said, there is a method that Virtualbox calls memory ballooning, due to the way memory is handled, that can serve basically the same purpose. In the documentation, there is a section just for Memory Ballooning. IMPORTANT COMPUTER SECURITY ALERT!March 31st, 2011 by Chris SunamiIf you can’t remove win32:malware-gen this is how we did it. NMP Consulting has encountered an aggressive new variant on the Malware0gen virus. This new version is extremely difficult to remove. The trickiest thing about this virus is that it creates and implements a seemingly legitimate Windows Service called “Windows System Express”. That service must first be disabled in order to locate and remove the hidden system file located in the system 32 directory. If you suspect you are infected with this virus, please call us immediately (614) 358-5814 DETAILS: In order to remove it: Get Your Facebook Privacy BackMay 18th, 2010 by Dan HillWith all of the news about the the privacy changes at Facebook, the Untangle team has create SaveFace to help you get your privacy set back to more restrictive settings, so that all your information is not available to everyone. It will set your privacy settings so that only your friends can access your information. It is easy to run and keeping your settings private is generally a good idea. PDF Files have Critical Security VulnerabilityApril 6th, 2010 by Rick ShanteryIt was released today on several sites that PDF files, and their corresponding readers have a critical vulnerability that would allow an attacker to compromise a computer, even with many of the normal protections in place that block things such as Javascript. Foxit Reader (NMP Recommended) and Adobe Reader both have fixes for this vulnerability. Go to http://www.foxitsoftware.com/pdf/reader/ and download and install the latest version. For Adobe Reader users, make the following preference change: From the Edit menu go to: Preferences -> Categories -> Trust Manager -> PDF File Attachments and then uncheck ‘Allow opening of non-PDF file attachments with external applications.’ This is a problem that could possibly affect all platforms and Operating Systems, whether Windows, OS X, or Linux. Bitdefender Update Causes a Boot Failure for some Windows UsersMarch 23rd, 2010 by Dan HillA problem with the Bitfender virus scanner mislabeled Windows system files as viruses and quarantined them. Therefore, without these files being available during the boot process, the computers fail to boot. This only seems to affect 64bit versions of Windows and they have made a patch available, which should be installed as soon as possible to avoid this issue. Information on how to get around the boot problem can be found on their website also. Corporate Password PolicyFebruary 20th, 2010 by rogueWhen setting up a office/corporate network environment, users may complain that it is frustrating to have to change their password every so often, or have to come up with difficult passwords. Despise the user’s arguments, although valid, remember the security risk that it poses. If you have simple passwords, maybe something common that all users share, it’s easy for unauthorized access into the system. If someone guesses or gets hold of one user’s password, it may be possible to guess the rest. Protect your data and files – enforce a password policy on your network, with an expiration on passwords. Use requirements such as at least one capital letter, and a number or special character to increase security. Your data is YOUR data – so make sure it’s safe from prying eyes! nmp consulting • 4002 north hampton drive • powell ohio 43065 info@nmpconsulting.com • phone 614.358.5814 • fax 614.437.1249 Columbus / Central Ohio area
