In part 1 of this series, I talked a bit about how encryption is shaping network performance monitoring (NPM). These technologies, however, are generally not effective at trying to gain visibility into traffic patterns traversing the internet. Let’s dive in deeper now….

Virtual Private Networks (VPNs) have become one of the cornerstones of secure communications over the internet. VPNs encapsulate data and encrypt the data using an algorithm contained within the transmission protocol. VPN traffic is encrypted and decrypted at the transmission and receiving ends of the connection.

Today, the internet (like most digital infrastructure in general) relies heavily on the security offered by public-key cryptosystems such as RSA, Diffie-Hellman (DH), and elliptic curve cryptography (ECC). But the advent of quantum computers has raised real questions about the long-term privacy of data exchanged over the internet.

In many infrastructures, the inflection points are at the network edge, where VPN gateways authenticate and encrypt remote-access traffic. This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN). More advanced VPNs can do this by application type.

In order for companies to realize SD-WANs cost savings and cloud performance benefits, branch offices must be connected directly to and communicate across the Internet. Traffic Protection The reliance on the public Internet requires the SD-WAN to protect traffic against eavesdropping. This requires a shift in our security models.

The core value proposition of SD-WAN is the use of a standard, low-cost Internet link to augment an expensive managed, low-latency and guaranteed capacity MPLS link. MPLS isnt encrypted by default: MPLS relies on the carrier private network for security because the data doesnt flow on the public Internet.

It provides a secure connection by encrypting traffic before being forwarded out to its destination over the internet. With that said, the two most common VPN protocols are IPSEC and SSL VPN. The TCP transport protocol is used instead of UDP and typically defaults to port 443 (can also be changed to a custom port).

SD-WAN is a flexible solution that integrates low-cost Internet transports into a virtual WAN connection. Myth 3: MPLS is Secure On its own, MPLS doesnt employ security protocols. Many MPLS customers today add VPN encryption to secure the network. However, because traffic is sent in the clear, they are vulnerable to wiretapping.
