Over 80% of network teams play a role in security efforts

More than 4 in 5 IT teams are involved in security efforts, and a majority of them report an increase of at least 25 percent in time spent on these efforts over the past 12 months, according to Viavi.

The most striking conclusion is that network-based conversation wire data has become the top data source for security incidents, with its use tripling, demonstrating that threat levels have driven enterprises to seek the most reliable forensic data available.

The State of the Network study captured the insights of Network Operations (NetOps) and Security Operations (SecOps) professionals worldwide, highlighting their challenges in security, performance management and deployment of new technologies.

Eighty-three percent of network teams are now engaged in supporting security issues, and of those, 91 percent spend up to 10 hours or more per week dealing with increasingly sophisticated security threats.

As hackers continue to circumvent existing security tools — even those with AI or machine learning — additional strategies are needed to quickly identify and contain security threats, the consequences of which can be devastating.

“This year’s State of the Network study highlights a clear way forward in today’s IT reality with a combination of prevention and ongoing detection to catch threats not flagged by security tools alone, such as an internal data breach by an employee, whether accidental or intentional.

“IT professionals need to better understand what is normal network behavior and what is not, and engage in proactive threat hunting,” said Douglas Roberts, Vice President and General Manager, Enterprise & Cloud Business Unit, VIAVI.

“Findings also show that network teams now depend on wire data as their most important source of information for security incidents, demonstrating that more NetOps teams are turning to the optimum peace of mind for issue resolution and compliance in the event of a breach.”

Key takeaways

Network teams are critical to protecting business resources and strengthening IT security. Increases in threat workloads were reported, with 74 percent of respondents stating they spend up to 10 hours or more per week on security. Three out of four of those teams report an increase of at least 25 percent of time spent over the past 12 months.

When asked how the nature of security threats has changed in the past year, IT teams identified a rise in email and browser-based malware attacks (59 percent), and an increase in threat sophistication (57 percent). Significant numbers of respondents also reported increases in exfiltration attacks on database servers (34 percent), application attacks (33 percent), DDoS attacks (32 percent) and ransomware attacks (30 percent).

Wire data has taken a central role in resolving suspected or known security threats, with 71 percent of respondents reporting that they used packet capture and 46 percent reporting that they used flow data, compared to 23 percent and 10 percent respectively in the 2017 State of the Network study.

NetOps teams play an active role in aiding SecOps before, during and after a threat has been detected, due to an increase in volume and sophistication of security threats.

Respondents highlight the importance of understanding normal network behavior and the ability to quickly hunt for malefactors when suspicious activity is noted.

Collaboration between SecOps and NetOps has accelerated, maximizing security initiatives and minimizing resolution time to limit negative impact to the business and customers.

While NetOps teams pivot to assist with security, they are still challenged to maintain acceptable service performance and end-user experience, despite the rapid deployments of new technologies and large increases in network traffic loads.
