Password Blacklist
Geo SCADA Expert allows you use password blacklists to restrict the creation and use of weak and commonly used passwords, for example:
- Your company name
- Common industry terms
- Local sports teams
- Local city names
- Employee names
- Popular celebrity names
- Common pet names
- The word “password”
Although the security settings within Geo SCADA Expert define the level of security and the structure of passwords, when users are required to create passwords the blacklist helps to eliminate passwords that might be easily guessed and in turn resist dictionary attacks by unauthorized users.
Example of a password blacklist source file
A password blacklist source file consists of a simple ASCII or UTF-8 text file, with Windows style line endings, that can be imported into Geo SCADA Expert. A file contains a list of common passwords that are used by the general public. These lists can range from a few hundred to a few thousand common dictionary words. The following is a sample of the contents of a source file:
