How to provide network security: recommendations for Radmin 2.x users
We at Famatech would like to give our users a few recommendations on how to increase their network security. If not enough attention is paid to the settings of both the Windows security system and of Remote Administrator software, malicious users could gain unauthorized access to your computers to upload and run any program. You will find recommendations on how to secure your Windows and Radmin to avoid such situation below.
Network security policy:
1. Never leave passwords to administrative accounts empty, especially when your computer is connected to the Internet directly with no firewall and/or NAT.
2. In order to provide information security do not share your %windir% folder (the folder where the OS is installed) or the entire hard drive containing this folder. Even limited to read-only access, a malicious user can copy system files (.pwl files, Windows registry files, etc) to their computer and extract the information from these files to illegally access your systems.
Double (and triple) check that only those folders you must share are shared and no others. Make sure they are only shared for specific users who need to use them. Avoid excess permissions (e.g., when Joe's permissions is not limited by \Users\Joe\ folder and Joe can access \Users\ folder):
1) Find a shared folder;
You can get a list of all the shared folders by using the NET SHARE command. For more detailed information on this, refer to the Microsoft Windows documentation.
3. When using Remote Administrator's own password, never leave Radmin Server passwords empty. Do not use dictionary words as a password. Such a password is not secure and can be easily tried using a dictionary. This is applicable to any password protected software.
4. If security policy is configured incorrectly, even an anonymous user can gain access to a remote computer's registry using the Remote Registry service. As Radmin Server stores it's encrypted password in
(It is theoretically possible for a malicious user to use an encrypted password to connect to a remote Radmin Server, but this would require coding an alternative client for Radmin Server.
We recommend the following actions to ensure your system is secure:
Security recommendations for Windows NT/2000/XP/2003:
I. Stop the Remote Registry service so no one can remotely access your Windows registry:
1. Go to Start->Run->Control Panel->Administrative Tools->Services;
II. Restrict access to
1. Go to Start->Run-> and execute regedt32;
Note: Now you must log on under a local user profile to run Radmin Server.
Security recommendations for Windows 95/98/ME:
I. Block the possibility of remote access to your Windows registry by following these steps:
1. Run Start->Settings->Control Panel->Network;
II. Make sure that you only share those folders that must be shared. Check that they are only shared for those specific users who really do need to use them (see above). Don't share your %windir% folder (the folder where the OS is installed and where the Windows registry is stored).
Respecting this simple network security policy you keep your information safe and confidential.
