You need to access your work computer from home, but the idea of someone digitally peeking over your shoulder makes you uneasy. Enter remote access tools for cloud servers. They allow employees to access their work computers, servers, and applications from any location and on any device. Even in adverse circumstances, your business operations can continue as usual, mitigating downtime and reducing the impact on productivity.

, we’ll provide insights and tips to keep your remote access connections safe, even if you're not a tech whiz. Learn how to securely use RDP, SSH, and VNC to ensure your data remains protected and your workflow uninterrupted.

Understanding Remote Desktop Protocol (RDP) and its functionality

What is RDP and How secure is Windows RDP?

Remote Desktop Protocol (RDP), offered by Microsoft, allows users to execute remote operations on other computers, providing secure information exchange between remotely connected machines over an encrypted communication channel. Widely used in corporate environments, RDP is a go-to for managing servers and providing remote support.

Despite its advanced security features like network-level authentication, RDP is vulnerable to cyberattacks. Nearly all inbound and outbound RDP connection requests happen at TCP ports, making it easier for cybercriminals to intercept communication between remote machines. To mitigate such risks, strong password management and firewall setups are recommended.

Securing RDP is vital to prevent unauthorized access and potential breaches. Here are some key practices:

 Ensure that all accounts with RDP access have strong, unique passwords to reduce the risk of brute-force attacks.

Enable Network Level Authentication (NLA):

 NLA adds an extra layer of security by requiring users to authenticate before establishing a full RDP session.

 Restrict RDP access to only those who need it and disable it for all other users.

 Adding 2FA to RDP sessions significantly enhances security by requiring a second form of verification.

 Regularly update your operating systems and RDP clients to protect against vulnerabilities and exploits.

 Regularly review RDP logs for any unusual or unauthorized access attempts.

Utilizing Secure Shell (SSH) for Cloud Access

Secure Shell (SSH) is a cryptographic network protocol that allows for secure remote access to computer systems. It's a popular choice for managing cloud servers and other Unix-based machines (like Linux and macOS) due to its strong authentication and encryption capabilities.


Implementing SSH securely involves the following practices:

Use SSH Keys Instead of Passwords: SSH keys provide stronger security than passwords and are less susceptible to brute-force attacks.

Disable Root Login: Prevent direct root login via SSH to minimize the risk of unauthorized administrative access.

Implement Fail2Ban: This software can help prevent brute-force attacks by banning IP addresses that show malicious signs.

Regularly Update SSH Software: Keeping your SSH software up to date ensures you have the latest security patches and improvements.

Restrict SSH Access: Limit SSH access to specific IP addresses or networks to reduce exposure to potential attackers.

Use Strong Encryption Algorithms: Ensure that your SSH configuration uses strong and modern encryption algorithms to protect data in transit.

Overall, SSH is a powerful tool for secure remote access, especially valuable for system administrators and those comfortable with command-line environments.

Understanding VNC and its working for remote access

Virtual Network Computing (VNC) is a remote access protocol that allows control of the desktop of another computer from your device. Operating on a client-server model, VNC is platform-agnostic and enables remote connections between different platforms. 

VNC operates on a client-server model. You need a VNC server installed on the remote machine you want to access, and a VNC client installed on your local device (computer, or phone). There are many free and paid VNC clients available for various OS. Depending on the VNC server configuration, you might be prompted for a password or other credentials to authorize access. This is crucial for security to prevent unauthorized users from controlling your machine. Unlike RDP or SSH (focused on Unix-based systems), VNC is platform-agnostic and as long as you're in it, you can establish a remote connection between different platforms (Windows to Mac, Linux to Android, etc.)

To secure VNC connections, consider the following:

Use Strong Passwords: Just like with RDP and SSH, strong passwords are essential for VNC security.

Enable Encryption: Some VNC implementations offer encryption options to protect the data transmitted over the network.

Restrict Network Access: Limit VNC access to specific IP addresses or networks to minimize the risk of unauthorized connections.

Use VPNs for VNC Connections: Establish VNC sessions over a Virtual Private Network (VPN) to add an extra layer of security.

Update VNC Software: Keep your VNC software up to date with the latest security patches.

Disable Unnecessary Features: Turn off features and services that are not needed to reduce potential attack vectors.

Overall, VNC offers a versatile and user-friendly solution for remote desktop access across different platforms. However, prioritize security by using strong passwords and encryption, especially for sensitive tasks.

How does secure remote desktop protocol access work?

Secure remote access starts with verifying who you are (user or device) through your organization's security system. Then, strict controls define who can access what system, when, from where, and what actions they can take. Once approved, you get a secure tunnel (no need to re-enter credentials) to access specific systems using RDP, SSH, or VNC. All this information is logged for further analysis, keeping your data safe.

General Security Tips for Accessing Cloud Servers

Beyond protocol-specific practices, here are some general tips to secure your remote access of your cloud servers:

Regular Backups: Ensure regular backups of critical data to recover quickly from any security incidents.

Network Segmentation: Divide your network into segments to contain breaches and limit the movement of attackers.

Security Audits: Conduct regular security audits to identify and address vulnerabilities in your infrastructure.

Educate Users: Train your staff on security best practices and the importance of safeguarding access credentials.

Implement Intrusion Detection Systems (IDS): Use IDS to monitor network traffic for suspicious activities and potential threats.

Maintain a Security Policy: Develop and enforce a comprehensive security policy that covers all aspects of cloud server access and management.

The Takeaway: Secure Remote Access is Key

Technology plays a crucial role in safeguarding your data, but your actions matter too. By understanding and implementing secure access methods like RDP, SSH, and VNC, and by following best practices, you can protect your cloud infrastructure from unauthorized access and potential threats. Prioritize security in all aspects of your remote access strategy to ensure a safe and reliable cloud environment. Remember, we all share the responsibility for ensuring the safety and security of our remote access practices.
