Automating Incident Response with PowerShell

Incident response involves taking swift and decisive actions to mitigate the impact of security incidents. PowerShell scripting can automate incident response processes, enabling rapid and consistent response actions across multiple systems.

Let's consider an example where we automate the process of isolating a compromised system:

```

$compromisedSystems = "ComputerA", "ComputerB", "ComputerC"

foreach ($system in $compromisedSystems) {

Invoke-Command -ComputerName $system -ScriptBlock {

# Execute commands to isolate the system, such as disabling network interfaces or firewall rules

# Perform additional actions, such as collecting forensics data or initiating remediation tasks

}

}

```

In this example, we utilize the `Invoke-Command` cmdlet to execute commands on multiple compromised systems simultaneously. Within the script block, we can include commands to isolate the system, collect forensics data, or initiate remediation tasks specific to the incident.
