What is virtual private network?
Virtual private networking protocols encapsulate PPP frames (the data units at the data link layer of the OSI model) into IP datagrams at the network layer. These datagrams are then sent across an internetwork, which can be either a private network or, more commonly, the Internet. This encapsulation creates a “tunnel” that acts like a dedicated WAN link, even though it usually uses the Internet—thus, a “virtual” private network.
Why do you want to be encrypted in a remote session?
First, you want the best security you can provide for the remote session.

Second, older systems and their associated protocols are less capable in terms ...
How does dial up authentication work?
Authenticating the user. Part of the dial-up process involves authentication, usually by providing a password. Since that password can be intercepted and used to gain unauthorized access, it should be encrypted using the strongest possible method that is supported by both the server and the client.
What is link encryption?
With link encryption, the data is encrypted only on the link (i.e., only to the remote access server); with end-to-end encryption, the data is encrypted from the client application to the server hosting the resource being accessed.
Why use certificates for authentication?
Using certificates for authentication prevents possible man-in-the-middle attacks.

Is remote access to OT commonplace?
Remote access to OT systems is now commonplace, especially driven by industry 4.0 applications, although it is not unique to these cases. Increasingly more companies are contracting out the development, assembly and commissioning of new machines that require remote access, so that the supplier can provide the technical support agreed upon in the contract. For clients, these accesses are an entry point to their network, so they should seek to make them as secure as possible and only use them when strictly necessary.
Is remote access to control systems secure?
As discussed above, there are various ways to remotely access control systems. Some are more secure than others, but, at the same time, they are more difficult to implement and deploy. We must always start from the premise that direct remote access to control systems is not recommended in all good practice guides and regulations, since external networks are considered insecure environments. Therefore, any measure taken will be beneficial to the security of the organization.

Businesses compromised through remote access systems
Many businesses use software that allows staff to access the business’ network remotely. Attackers are using this software to gain access to business networks, extract sensitive data, and encrypt files. They then demand payment for the data.
What's happening
Attackers access an organisation's network through their remote access software, such as remote desktop protocol (RDP) and virtual private networks (VPN). They gain access through weak passwords, a lack of two-factor authentication, or software that’s not up-to-date.
What to look for
Any business that uses remote access but isn’t using two-factor authentication and using strong passwords is at risk. The software also needs to be up-to-date to fix any security vulnerabilities that have been found.
