サマリー

米国調査会社ヘビーリーディング社(Heavy Reading)の調査レポート「SD-WANフォーカスグループ:今はいいけど先々不安なセキュリティ問題」は、SD-WANに関する専門家であるサービスプロバイダの従業員への質疑応答から作られた。このフォーカスグループに対してセキュリティ全般、技術、SD-WANセキュリティに関連する外部からの影響などに関する10の質問を行った。その結果、サービスプロバイダはSD-WANセキュリティに関して十分対策していると考えているが、この状態を継続するにはさらなる対策が必要であるだろうということが分かった。

EXECUTIVE SUMMARY(PDF)

More than three-quarters of panelists in this month's Thought Leadership Council (TLC) forum say their company's overall knowledge about software-defined wide area network (SD-WAN) security is either good or excellent. The 11 panelists in this month's forum are service provider experts in SD-WAN.

The panelists were asked to grade their company's current level of knowledge concerning SD-WAN security, and the majority gave their companies a B score. One such panelist, who said his company already has three SD-WAN projects in progress, including one already in production, said, "To improve SD-WAN security, we need clearer business requirements to understand SD-WAN's position within the product portfolio. We also should move the data center to OpenStack to host SD-WAN in a more distributed way."

About 35 percent of panelists surveyed say their companies have completely implemented a full security strategy for SD-WAN, and another 25 percent say they will have done so by the end of this year.

The Council circumvents traditional industry hype to ascertain how service providers are really responding to important industry technologies and trends. What makes this initiative so unique is that participants discuss issues in a completely anonymous forum, enabling them to share insights and express business realities that otherwise could not be shared.

SD-WAN Focus Group: Security Good for Now, but Don't Rest on Laurels was generated from a Q&A with service provider employees who are experts on SD-WAN. This focus group was asked 10 questions about overall security, technology and outside influences related to SD-WAN security. The results clearly indicate that service providers believe they're doing a good job on SD-WAN security but need to consider some enhancements to continue doing so. 

TLC members were asked to grade their company's current level of knowledge regarding security for SD-WAN, using a traditional grading system in which A=excellent, B=good, C=average, D=needs improvement and F=failing. Results are shown in the excerpt below. Forty-six percent of panelists gave a score of B, indicating their company's overall knowledge of SD-WAN security is good job, while 36 percent of panelists gave a score of A, indicating the level of knowledge about SD-WAN security is excellent.

Service Providers Have Work Ahead for SD-WAN Security

Heavy Lifting Analyst Notes
Denise Culver, Online Research Director

The majority of service provider experts say they feel pretty confident about how their companies are handling software-defined wide-area networking (SD-WAN) security as part of this month's Thought Leadership Council (TLC).

Nevertheless, more than 80% of those experts say it's imperative for their companies to continue researching, developing and investing in security because it's just a matter of time before those companies experience a security breach that affects SD-WAN.

Specifically, more than 50% of TLC panelists think their companies will experience a security breach that directly affects SD-WAN service within two years. About 20% more say it will happen within five years. One panelist admits his company already has experienced such a breach.

But, overall, TLC panelists say their companies are aware of major security pitfalls and have attainable options for strengthening SD-WAN security, as found in the newest TLC report, SD-WAN Focus Group: Security Good for Now, but Don't Rest on Laurels. Council members were asked a series of ten questions about overall security, technology and outside influences related to SD-WAN security.

The report also shows that TLC members think service providers should focus on established technologies to secure SD-WAN. When asked to determine the most important technologies for their company's SD-WAN security plans, 100% of TLC members chose both distributed denial of service (DDoS) and encryption as being critical.

Likewise, more than 90% of panelists said next-generation firewalls (NGFWs) are critical to SD-WAN security. One panelist explained, "SD-WAN security creates the need to look beyond simple or individual applications and mechanisms for more advanced attacks. Security solutions should understand relations between different patterns and attacks on different systems."

Another key takeaway in the report is that service providers are best at securing the network layer in relation to SD-WAN. TLC panelists gave their companies scores of either A or B in relation to securing the network layer. Scores were quite a bit lower for maintaining security integrity over the entire lifecycle, where more than 50% of panelists scored their companies as either average or needing improvement.

TLC is a Heavy Reading research initiative that consists of panels of communications service provider experts focused on key areas of telecom development, including B/OSS Transformation, SD-WAN, Automation, 5G, Emerging Technologies & Services (Project 2025) and IoT. Members participate in Q&A forums several times a year, and all information disclosed by Council members remains anonymous.
