1. TYPES OF REMOTE ACCESS

2. What Is Remote Access? Remote access is the ability for an authorized person to access a computer or a network from a geographical distance through a network connection. Remote access enables users to connect to the systems they need when they are physically far away. If you gave the caller access, you've exposed your PC security to them. A more clever way the scammers may try to reach you is by tricking you into downloading malware onto your PC, which then flashes a warning that you have a virus and need to contact "tech support" to have it removed.

3. A Brief History: As networked computing became more mainstream in the 1970s and 1980s, remote terminal access was used to interact with the large central computers. The first remote terminal interfaces assumed a high level of trust between the central computer and all those on the network, because the small, centralized networks used were physically isolated from one another.

4. A Brief History: In the late 1960s, the Telnet protocol was defined and started being used over TCP networks (normally on port 23) for remote control over larger private networks, and eventually the public Internet. Telnet's underlying technology (a text-based protocol to transfer data between different systems) was the basis for many foundational communications protocols in use today, including HTTP, FTP, and POP3. However, plain text streams are not secure, and even with the addition of TLS and SASL, Telnet was never very secure by default. With the advent of SSH (which we'll get to in a bit), the protocol has declined in popularity for most remote administration purposes.

6. Evolution Of Remote Access: • In some circumstances, just establishing a connection can take some time. Additionally, once connected, the delay inherent in SSH's TCP interface (where every packet must reach its destination and be acknowledged before further input will be accepted) means entering commands or viewing progress over a high-latency connection is an exercise in frustration. • Mosh, "the mobile shell", a new alternative to SSH, uses SSH to establish an initial connection, then synchronizes the following local session with a remote session on the server via UDP. • Mosh also promises better UTF-8 support than SSH, and is well supported by all the major POSIX-like operating systems (and can even run inside Google Chrome!). • It will be interesting to see where the future leads with regard to remote terminal access, but one thing is for sure: Ansible will continue to support the most secure, fast, and reliable connection methods to help you build and manage your infrastructure!

7. Types Of Remote Access: 1. VPNs: Virtual Private Networks: "Virtual Private Network" and describes the opportunity to establish a protected network connection when using public networks. VPNs encrypt your internet traffic and disguise your online identity. This makes it more difficult for third parties to track your activities online and steal data. To fully achieve its goals, a VPN must accomplish two important tasks: • Create the connection or tunnel; and • Protect that connection, so that your files (and your company’s network) won’t be compromised.

8. 2. Desktop sharing: • Desktop Sharing is another way organizations can provide remote access to users. These software tools can provide real-time sharing of files, presentations, or applications with coworkers, vendors, or other clients. There are many applications made possible by desktop sharing including remote support, webinars, and online conferences with audio and visual content (presentation sharing), and real-time global collaboration on projects. • Another application of desktop sharing is remote login for workers who need access to their work computers from any Web-connected device (desktop, laptop, phone, or tablet).

9. 3. PAM: Privileged Access Management: • PAM is a set of tools and technologies that can be used to secure, control, and monitor access via privileged accounts to an organization’s resources. The most effective PAM solutions address several areas of information security defense, such as advanced credential security, systems, and data access control, credential obfuscation and user activity monitoring. Ensuring continuous oversight of these target areas helps lower the threat of unauthorized network access, and makes it easier for IT managers to uncover suspicious activity on the network. • Best practices in PAM indicate that least privilege protocols should be enforced, where users only have access to the specific limited resources they need, rather than free reign to roam the entire network. In addition, network managers should be able to restrict or expand user access as needed, in real-time.

10. Choosing your platform: We have seen that there are several options available to organizations when it comes to providing users with remote access, but these often come with limitations or drawbacks. VPNs may be good for internal employees, but are not optimal for third-party vendors. Desktop sharing tools may be useful for desktop support and helpdesk, but are not good for complex enterprise remote support. PAM provides improvements over VPN and desktop sharing, but there is only one solution that combines the best of all these remote access technologies into one and is purpose-built for vendors and doesn’t include any of the drawbacks: VPAM.
