Not long ago, remote access was reserved for a select few, such as traveling salespeople and senior executives. Today, it has become ubiquitous. Indeed, users across many roles and functions in the modern office now routinely connect to the corporate network from off-site locations and work with resources as if they were connected to the local network.
However, allowing users to access corporate resources remotely introduces security risks, so robust management is vital. This article provides the key information organizations need to implement remote access securely and effectively.
Key Technologies in Remote Access
Remote access technologies have evolved over the years. Some of the popular alternatives today include the following:
- Virtual Private Network (VPN) has been the de facto standard for many years. It allows remote users to access the corporate network securely using encrypted connections over the internet.
- Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft. It is commonly used by IT support personnel to remotely access, control and troubleshoot another Windows computer over a network connection.
- Third-party remote access solutions offer alternatives to Remote Desktop Protocol for remote access and control of computers. Examples include TeamViewer, LogMeIn, and GoToMyPC. Vendors and external support teams commonly use these tools to securely access and troubleshoot corporate resources without the need for a direct VPN connection to the organization’s network.
- Secure Shell (SSH) is a secure network protocol that provides encrypted communication and remote command-line access to servers and other devices. IT professionals commonly use it for remote administration and management tasks.
Securing Remote Connections
Allowing remote access to the corporate network makes critical systems and data more vulnerable to cyber threats. Some of the technologies used to secure remote access include the following:
- Encryption ensures that data transmitted over remote connections is unreadable even if it is intercepted. Standard encryption protocols include TLS, IPsec and AES.
- Multifactor authentication (MFA) adds a layer of security by requiring at least two authentication methods, such as a password plus a fingerprint or code sent to a user’s device.
- Access controls restrict user permissions to only what is necessary for their job role, adhering to the principle of least privilege. This minimizes the damage that the user could do, deliberately or accidentally, as well as the impact if the account were compromised by an attacker.
- Secure gateways, such as a VPN solution, are network appliances or installed software that provide secure remote access to corporate resources by authenticating users, enforcing access policies and encrypting connections over untrusted networks like the internet.

Implementing Remote Access Solutions
Implementing a remote access system is a complex process that requires careful planning and execution. Here are the key steps:
- Conduct a thorough assessment. The goal is to gain an in-depth understanding of your workforce’s specific requirements and preferences.
- Evaluate possible solutions. Be sure to consider scalability, security and cost factors, and ensure that your network and servers can support the candidate solution.
- Develop a deployment plan. Outline the implementation steps, timeline and required resources. The plan should include any upgrades to your existing hardware or software components.
- Integrate the solution. Adjust your existing infrastructure, such as firewall policies or router settings, and integrate the solution with your on-premises or cloud directory services. Configure access controls to enforce the principle of least privilege.
- Install the remote access software. Install the solution on your servers and deploy any required client software to users. Configure the solution to meet your requirements.
- Conduct thorough testing. Ensure that the system works as expected under different scenarios. This includes testing various user roles and access levels to verify that the remote access solution performs reliably and securely in all potential use cases.
- Provide comprehensive training. Ensure that all users know how to use the remote access system properly.
Management Tools for Remote Access
While preventive controls like MFA and encryption are vital to security, they are not sufficient. To ensure security, compliance and operational efficiency, organization needs to closely audit remote access sessions for suspicious activity, keep devices and applications updated, monitor the health of their systems.
Most networks come equipped with basic remote access monitoring and management tools. For instance, Windows Server includes Event Viewer for reviewing system and application logs, as well as the Windows Remote Management (WinRM) service, which enables administrators to manage Windows systems using PowerShell commands and scripts remotely. However, these manual tools require significant time and effort from security personnel.

Optimizing Performance in Remote Access Systems
When workloads must traverse long distances, latency becomes a significant issue. The following tips can help optimize availability, performance and reliability of remote access:
- Use high-speed, low-latency network connections for servers.
- Implement quality of service (QoS) policies to prioritize remote access traffic over non-critical traffic.
- Deploy load balancing and failover mechanisms to distribute traffic across multiple servers.
- Leverage content delivery networks (CDNs) or edge servers to reduce network latency for geographically dispersed users.
- Implement scalable, elastic architectures that dynamically allocate resources based on demand, seamlessly handling high traffic while maintaining service quality.
- Invest in a dedicated monitoring and analytics solution to track performance metrics and identify bottlenecks so you can proactively address issues.
- Look for solutions that offer advanced compression and encoding techniques that minimize bandwidth usage and latency.
