Traditional firewall security simply cant keep up with the challenges created by these new network paradigms. As a result, when I discuss firewall security with enterprises today, there are three reoccurring themes: visibility, scalability, and convergence. Lets find out.

Firewalls Evolve Over the Years Before the UTM, there was the basic firewall. All traffic passed through the firewall for basic inspection of security policies based on network information such as the type of protocol or the source/destination addresses.

Routing is performed by routers, firewalls, multi-layer switches and gateways. Any host that is not part of the source device network can be reached through the default router or gateway. From this configuration, NIC of a device know its default gateway to forward traffic to another network.

If you’re like many of the IT leaders we encounter, you’re likely facing a refresh on your firewall appliances or will face one soon enough. And while the standard practice was to exchange one firewall appliance for another, increasingly, enterprises seem to be replacing firewall appliances with firewall-as-a-service (FWaaS).

Live streaming is challenging because the video content is sent over the internet in near real-time. Sending a large volume of video content over the internet takes time. When a device wants to access the internet, it sends a request to your router. The modified request is sent to the internet. But how does it work?

A growing percentage of Internet traffic is protected by encryption. While estimates vary, most agree that at least 80% of Internet traffic uses SSL/TLS to ensure confidentiality, integrity, and authenticity of the data being transmitted. According to Google , approximately 95% of web browsing uses the encrypted HTTPS protocol.

When more of the workforce shifts to working remotely, it puts new and different strains on the infrastructure across different parts of the network, especially where VPN gateways connect to the network edge. This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN).

The Dutch engineering company had built a global wide area network (WAN) out of MPLS and Internet services connecting 17 locations 14 in Europe and 3 in the Asia Pacific with about 800 mobile and field employees. Users increasingly complained about their Internet performance. And MPLS did nothing for his security architecture.

Firewall as a Service (FwaaS) a firewall delivered as a cloud-based service. Unlike appliance-based firewalls that require management of discrete firewall appliances, FwaaS is a single logical firewall in the cloud that can be accessed from anywhere. For example, an MPLS connection and an Internet connection.

Back then life was much simpler for networking and security professionals.

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 bandwidth is expensive (relative to Internet capacity) and often limited or unavailable on some routes, forcing companies to either pay exorbitant fees to connect locations or, more likely, resort to Internet-based VPNs, complicating network design. With SD-WAN, companies avoid consuming expensive MPLS capacity on Internet traffic.

MPLS came of age when users worked in offices, resources resided in the datacenter, and the Internet was an afterthought. It was hopelessly out of step with a world that needed to move fast and one obsessed with the Internet. High Availability (HA) becomes a headache: With SD-WAN relying on Internet connections, HA is all but required.

The PoP is just a connection point a gateway, of sorts where the external world (i.e., site to site traffic), or to the general Internet.

The MPLS architectures of most enterprise WANs adds far too much latency to Internet- and cloud-destined traffic. Other problems, including extensive deployment times (as much as 90 days) and high bandwidth costs (think double or more their Internet equivalents), make MPLS incompatible with evolving enterprise requirements.

Most SD-WAN vendors provide basic security features such as encryption, layer 2 access control, and possibly some basic firewall functionality. By using service insertion or service chaining, separate security services such as firewalls and IPS are inserted into the data flow. Generally around 3-5 is enough.
