Are Enterprises Aware of the Latest SD-WAN Security Concerns?

By Enterprise Networking Mag | Tuesday, September 15, 2020

Security of SD-WAN has become a big concern these days. It has become vital to understand the significance of cabling in wireless environments as well as hard-to-detect new security attack.

FREMONT, CA: In this technical world, out of all the different kinds of security, software-defined WAN security, i.e., SD-WAN is being largely deployed by enterprises.

However, the only similar elements found between the different SD-WAN offerings in the market are the separation of the data plane, the control plane, and the control plane’s takeover by an SD-WAN controller. Having a look at the security architecture and the key management comprehensively is a part of the due diligence. There are distinct approaches available for implementing network security; each of them have their own advantages and disadvantages.

Enterprises that are considering SD-WAN rollouts must determine whether the prospective products are meeting crucial security thresholds. For example, it is vital for products to support cryptographic protocols and algorithms and meet present key management criteria.

The organizations cannot go very far by underpinning the wireless LAN without good and reliable wiring. In this fast ethernet world, the flaky cable can still work; however, with the evolving multigig wireless, an old cable can become the source of many problems.

DDoS Attacks and the long tail attacks

Similar to distributed denial of service, or, DDoS attacks, another technique called dubbed tail attacks, can easily clog networking resources.

However, unlike conventional DoS or DDoS attacks that possess the capability of overwhelming the bandwidth or TCP sessions, tail attacks do the job of concentrating on resource pools, such as storage nodes. In this kind of situation, there is a possibility that a targeted node might be struggling due to full queues. This circumstance can lead to a situation which can cause dependent nodes to shut down as well. These tail attacks do not need a lot of traffic and identifying them is itself a very tough task.

For now, the tail attacks are not that much common; however, they need attackers to have good knowledge about a specific network prior to they are launched.

Therefore, network managers need to be aware of all these new security attacks and enterprises need to understand the importance of right cabling in wireless environments.
