AvoidUsingComputerNameHardcoded

Severity Level: Error

Default state: Always enabled

Description

This rule detects hard-coded computer names in the ComputerName parameter of cmdlets. Hard-coded computer names can expose sensitive information and reduce script portability. The ComputerName parameter should always be parameterized or dynamically assigned to ensure scripts are flexible and secure.

Use parameters, environment variables, or dynamic values instead of hard-coded computer names.

Example

Noncompliant

Function Invoke-MyRemoteCommand ()
{
    Invoke-Command -Port 343 -ComputerName HardcodedRemoteHostname
}

Compliant

Function Invoke-MyCommand ($ComputerName)
{
    Invoke-Command -Port 343 -ComputerName $ComputerName
}

Configure rule

This rule is always enabled and isn't configurable. Use one of the following methods to avoid using this rule:

  • Create a custom rule configuration file to include only the rules you want or exclude the rules you don't want.
  • Add the appropriate rule suppression attributes to your code to suppress the rule for specific code blocks. For more information, see the Suppressing rules section of Using PSScriptAnalyzer.
