Hello,
Based on your description, here are each Group Policy Object (GPO) setting you provided and its potential advantages and disadvantages.
- Configure Redirection Guard: Enabled
Pros:
Enhances security by preventing attacks that rely on printer redirection, such as unwanted or unauthorized printing of sensitive documents.
Cons:
May cause issues with legitimate printer redirection scenarios, such as those used in Remote Desktop or Virtual Desktop Infrastructure (VDI) environments.
- Configure RPC connection settings: Protocol to use for outgoing RPC connections: Enabled: Redirection Guard Enabled
Pros: By specifying a protocol for outgoing RPC connections, you can standardize and potentially secure the communication between client and printer servers.
Cons: If the specified protocol is not supported or misconfigured, it could result in connectivity issues.
- Configure RPC connection settings: Use authentication for outgoing RPC connections: Enabled: Default
Pros:
Increases security by requiring authentication for outgoing RPC connections, helping to prevent unauthorized access.
Cons:
May introduce overhead or compatibility issues if certain services or applications do not support authenticated RPC connections.
- Configure RPC listener settings: Configure protocol options for incoming RPC connections: Enabled: RPC over TCP
Pros:
Standardizes incoming RPC connections to use TCP, which can be more reliable and easier to troubleshoot than other protocols.
Cons:
Limits flexibility if applications or services expect to use different protocols for RPC.
- Configure RPC listener settings: Configure protocol options for incoming RPC connections: Enabled: Negotiate or higher
Pros:
Ensures a higher level of security by negotiating the best available security protocol for incoming RPC connections.
Cons:
Potential increase in resource usage and possible compatibility issues with older applications that do not support advanced negotiation mechanisms.
- Configure RPC over TCP port: Enabled: 0
Pros:
Setting the port to 0 allows the system to dynamically allocate ports for RPC over TCP, which can simplify management and avoid port conflicts.
Cons:
Dynamically allocated ports can be harder to manage and monitor, making it more challenging to troubleshoot connectivity issues.
- MS Security Guide: Configure RPC packet-level privacy setting for incoming connections: Enabled
Pros:
Enhances security by ensuring that incoming RPC connections use packet-level privacy, which helps to protect data integrity and confidentiality.
Cons:
Can introduce additional overhead and complexity, possibly affecting performance or compatibility with older systems.
I hope the information above is helpful.
Best Regards,
