What is the purpose of remote desktop software?
-
To allow a user to access and control a remote computer’s desktop.
-
What protocol does Windows use for remote desktop functionality?
-
Remote Desktop Protocol (RDP).
-
What is a key security feature of RDP?
-
Encryption of authentication and session data to prevent unauthorized access.
-
What is a limitation of RDP in multi-user environments?
-
Only one user can be signed in at a time; starting an RDP session locks the local desktop.
-
How do users connect to a Windows RDP server?
-
Open the Remote Desktop Connection shortcut or run mstsc.exe and enter the server's IP address or FQDN.
-
What additional security setting protects RDP from denial of service attacks?
-
Network Level Authentication (NLA).
-
What is the purpose of NLA in RDP?
-
To authenticate users before committing resources to their session, protecting against DoS attacks.
-
Why should RDP be configured for least privilege?
-
To limit access to only necessary users and minimize security risks.
-
What protocol does macOS use for remote desktop functionality?
-
Virtual Network Computing (VNC).
-
How does VNC compare to RDP?
-
VNC is similar but typically used on non-Windows systems like macOS, working over TCP port 5900.
-
What is SSH, and what does it connect to?
-
Secure Shell (SSH) connects users to a command-line interface rather than a desktop.
-
Which port does SSH use by default?
-
TCP port 22.
-
How does SSH ensure secure communication?
-
It uses a host key fingerprint to verify server authenticity and encrypts the session.
-
Which port does RDP use by default?
-
TCP port 3389.
-
How do you change the Remote Desktop access settings on Windows?
-
Open the Remote Desktop page in the Settings app or System Properties.
-
How do you add specific users to access a Remote Desktop server?
-
Use the Select Users option to specify allowed accounts; local admins have access by default.
-
What is RDP Restricted Admin (RDPRA) Mode?
-
A security feature that reduces exposure of credentials when connecting to a potentially compromised server.
-
What is Microsoft Remote Assistance (MSRA)?
-
A feature that allows users to request help via an invitation file protected by a passcode.
-
How does Quick Assist differ from MSRA?
-
Quick Assist uses HTTPS (port 443) for secure remote help, while MSRA assigns ports dynamically.
-
What limitation do both MSRA and Quick Assist have regarding User Account Control (UAC)?
-
Neither allows helpers to perform tasks that require UAC consent without lowering UAC settings.
-
Name two third-party screen-sharing tools.
-
TeamViewer and LogMeIn.
-
How do screen-sharing tools like TeamViewer enhance security?
-
They use encrypted HTTPS connections and typically require a PIN code for session access.
-
How can users securely transfer files on Apple devices?
-
Using AirDrop, which creates a secure Wi-Fi Direct connection for file sharing.
-
What file-sharing feature is built into Windows?
-
Nearby Sharing, which works similarly to AirDrop.
-
What is Nearby Share on Android devices?
-
A Bluetooth-enabled feature for secure file sharing.
-
How does a VPN secure remote connections?
-
By establishing a secure, encrypted tunnel between the local device and a remote network.
-
Why would you use a VPN with remote desktop software?
-
To add an extra security layer, avoiding the need to open additional firewall ports.
-
What are Remote Monitoring and Management (RMM) tools used for?
-
To enable managed service providers (MSPs) to monitor and manage client IT environments.
-
What functionality do Unified Endpoint Management (UEM) suites typically include?
-
Access control, inventory, updates, and remote desktop capabilities for organizational IT.
-
What is an advantage of using an RMM tool?
-
It provides reporting and billing features for managed service providers.
-
How do UEM tools improve network security?
-
By enforcing health policies and restricting access to non-compliant devices.
