<\/p>

Remote access is a business necessity. Around 50% of workers<\/a> use remote access technologies to work from home or on the move. Many of those workers access remote desktops to recreate workplaces outside the office.<\/p>

While workers see Office 365 or SalesForce on their displays, a lot<\/i> happens under the hood. Businesses rely on remote access protocols to connect devices and transfer data<\/b>. In every case, companies must secure remote access methods while ensuring optimal performance.\u00a0<\/p>

This blog will explore remote access protocols and introduce some popular varieties. We will also list some remote access best practices to help you find the perfect setup.<\/p>

What are remote access protocols?<\/h2>

Remote access protocols enable connections between remote devices and servers<\/b>. Protocols set the conditions for transferring data packets, allowing workers to access desktops hosted on centralized data centers. Many protocols also strengthen security by applying encryption to hide traffic from outsiders.<\/p>

Common types of remote access protocols<\/h2>

Almost every device has an in-built remote access protocol. Windows uses the Remote Desktop Protocol (RDP), while Linux and Macs use the Secure Shell Protocol (SSH).<\/p>

Protocols have default settings, which often suit user needs. However, there are occasions when customizing remote access protocols is essential. You may also add extra protocols to improve security or ensure compatibility with other systems.<\/p>

When you deviate from default setups, it\u2019s important to understand how remote access protocols work. Let\u2019s explore the main remote access protocols and how to use them.<\/p>

Remote Desktop Protocol (RDP)<\/h3>

Microsoft created the Remote Desktop Protocol in 2012. RDP<\/a> uses a server and client setup to organize shared connections between remote devices and central servers<\/b>. Engineers use RDP to access remote devices securely, and the protocol works with Windows, Linux, Mac OS, and even Android.<\/p>

RDP uses port forwarding and the TCP\/IP transfer protocol to send and receive data over a network channel. This channel carries data about keystrokes, mouse movements, and visual information from remote servers<\/b>.<\/p>

With RDP, users don\u2019t need to host apps on their devices. They can access central assets via RDP and work via the remote desktop.<\/p>

Secure Shell (SSH)<\/h3>

The Secure Shell remote transfer protocol allows remote users to deliver command-line instructions<\/b> to central devices. The SSH<\/a> protocol encrypts commands and enables secure file transmission. These features make it a popular protocol for server management.<\/p>

SSH may also be a good option for <\/b>secure remote access<\/b><\/a>. The SSH protocol uses public and private keys to authenticate connections. RDP relies on password credentials supplied by remote users, which can be vulnerable to theft or brute force attacks.<\/p>

Virtual Network Computing (VNC)<\/h3>

Like RDP, VNC<\/a> users remotely control applications stored on central servers. Unlike RDP, VNC uses the Remote Frame Buffer Protocol (RFB). The screen-sharing protocol<\/b> allows remote capture of devices, providing greater control compared with RDP.<\/p>

VNC is popular because it is platform-independent. <\/b>Many users can connect to a VNC instance, regardless of their operating system. It is a common choice for IT or customer service teams who need secure access to user devices.<\/p>

Serial Line Internet Protocol (SLIP)<\/h3>

SLIP is one of the oldest remote access technologies, having appeared in the 1980s. First used to connect Unix devices, SLIP is still a popular way to control TCP\/IP data transmission.<\/p>

SLIP creates point-to-point pathways between serial devices<\/b>. Serial communication is rarely used in remote working as it struggles with audio-visual data flows. However, companies commonly use the technique to control internet-of-things devices due to its low cost and simplicity.<\/p>

Point-to-point protocol (PPP)<\/h3>

Point-to-point protocols use TCP\/IP to create secure connections between remote devices and central servers. Operating at the link layer, PPP is a go-to protocol for Internet Service Providers.<\/p>

PPP is the foundation of other remote access technologies. For example, Point-to-Point Protocol over Ethernet<\/b> (PPPoE) allows rapid file transfers over Ethernet connections. PPPoE also enables network monitoring to track user activity.<\/p>

Virtual Private Networks (VPNs)<\/h3>

Virtual Private Networks<\/b><\/a> <\/b>use variants of the Point-to-Point Tunneling Protocol (PPTP) to create secure tunnels between clients and servers. Tunneling enhances user privacy by encrypting data and assigning fresh IP addresses<\/b>.<\/p>

These features make VPNs some of the most secure remote access solutions. However, VPN protocols are not specialized for remote desktop access. They tend to operate alongside RDP and other remote access technologies.<\/p>

Remote access VPNs<\/a> create digital gateways to secure other forms of remote access<\/b>. That’s especially useful for remote workforces that connect via home offices and unsecured public networks.<\/p>

VMWare Blast<\/h3>

Blast is VMWare’s virtual display protocol and uses the H.264 video compression standard to transfer video data. Compression makes Blast a good option if companies rely on video conferencing and virtual meetings. <\/b>It also suits remote desktop access with complex visual demands.<\/p>

VMWare Blast is platform-neutral, supporting Linux, MacOS, and Windows. It uses the UDP and TCP\/IP framework for data transfers, while encryption and authentication functions provide additional security.<\/p>

Citrix ICA<\/h3>

Citrix ICA is a proprietary remote desktop protocol focused on high-performance desktop access.<\/p>

The “Independent Computing Architecture” resembles RDP’s client and server architecture. Unlike basic RDP, Citrix ICA optimizes data flows for graphics and audio. This reduces latency and enhances efficiency.<\/p>

Hypertext Transfer Protocol Secure (HTTPS)<\/h3>

HTTPS is a secure version of the Hypertext Transfer Protocol that transmits most web traffic.<\/p>

Companies can use it to secure remote access via web applications. For example, HTTPS enables collaboration via Google Docs or access to publishing tools like Canva.<\/p>

The problem with HTTPS is it only applies to web-based traffic. Users will need additional protocols to secure other forms of traffic.<\/p>

Apple Remote Desktop (ARD)<\/h3>

Apple’s version of the Remote Desktop Protocol, ARD, allows remote management of MacOS systems. It provides similar services to RDP, including remote admin and file transfers.<\/p>

IT teams can use ARD to remotely manage software on Apple devices or control many Macs on a company network. ARD also features screen-sharing, file distribution, and software installation to ease the workload for security teams.<\/p>

ARD is only used with Apple systems. You can use it as part of remote access systems, but other protocols are needed if PCs or other devices are involved.<\/p>

How should you choose the right remote access protocol for your needs?<\/h2>

Take care when choosing different types of remote access protocol, as the protocol you select influences overall performance.<\/p>

Remote access solutions should balance criteria and take business needs into account. In some situations, security is critical. In others, speed matters slightly more. Here are some criteria to guide your decision-making:<\/p>
