The changing nature of Web security threats

By adminNo Comments

The Internet has come a long way, today we are seeing the web broaden its reach to an ever-widening range of devices, and with increasing levels of interaction. Communications services such as WebEx and Skype take advantage of the greater bandwidth available in both home and mobile environments, and in the meanwhile social networking sites such as LinkedIn, Facebook and Twitter have become an integral part of many communication strategy.

While all this is well and good and has many benefits, this is a double edged sword. We need to turn our attention to the security risks that are related to new methods of interaction, as they pose a new threat. Many organisations still see web security as relating to viruses and malware infecting unprotected desktops.

Now is the time to review your security policy, including anti virus, firewall, web useage policy and even data security to prevent theft

email issues – Backscatter (e-mail)

By adminNo Comments

Backscatter is incorrect automated bounce messages sent by email servers usually associated with incoming spam. Backscatter occurs because spam messages forge their sender address, and mailservers configured by naive administrators send a bounce message to this address.

The easiest way is to not to issue NDR from your server

This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator

By adminNo Comments

When trying to click on a hyperlink within an email I get the following error;
“This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.”

I am the administrator of this computer. How can I use these deactivated links again?

This usually happens when there is no default Internet browser (properly) registered in Windows.

To recover, it often is enough to reassign a default browser via;

  • Windows Vista and Windows 7
    Start-> Default Programs
  • Windows XP
    Control Panel-> Set Program Access and Defaults

When you have multiple browsers installed, it sometimes helps to set the other browser as the default, apply the changes and then set your preferred browser as the default again.

If you only have a single Internet browser installed in Windows Vista or Windows 7, you can also deselect all the defaults for the browser by pressing “Choose defaults for this program”, save the changes and then select them all again.

Reset the browser
Depending on your Internet browser, you might additionally need to reset the browser. For Internet Explorer this can be done in Control Panel-> Internet Options. When you use Internet Explorer 6 or lower, you’ll find this option on the Programs tab. For Internet Explorer 7 and 8, you can find this option on the Advanced tab.

For Firefox, open a Run command and type the following (note the spaces);
firefox -safe-mode firefox-safe-mode

In the dialog that pops-up select the option “Reset all user preferences to Firefox defaults” and press “Make Changes and Restart”.

Registry fix
If resetting via the conventional means does not work out for you, then the issue is probably rooted a bit deeper and are the file associations and handlers not correctly registered in the registry or are conflicting. To resolve this, you can download this registry file.

This zip-file contains 3 files;

  • readme.txt                                          Some information over the zip-file itself
  • ie-fix-restrictions-Win32.reg           For when using a 32-bit version of Windows
  • ie-fix-restrictions-Win64.reg           For when using a 64-bit version of Windows

This registry file contains the minimal amount or registry entries needed for making Internet links open again with Internet Explorer. All these registry entries are original entries which are also there when you do a clean installation of Windows.
If found, it also removes some registry entries which could conflict with the original entries. These registry entries also do not exist when doing a clean installation of Windows.

Note 1: For importing this registry file you’ll need to have Administrator rights on the computer.

Note 2: The registry keys are based on a default installation of Windows on the C:\-drive. If you installed Windows to another drive letter or if you want to see what’s inside the reg-file before importing it, you can extract the zip-file and then open/edit it in Notepad by right clicking on the reg-file and choosing Edit.
