These figures illustrate the pivotal role of DNS for network security, both as a threat vector and security objective.

Around a quarter of companies have suffered a DNS attack abusing cloud misconfiguration, with 47% of companies suffering cloud service downtime as a result of DNS attacks.

Although the cost and variety of attacks remains high, there is a growing awareness of DNS security and how to combat these attacks.

76% of respondents in the report deemed DNS security a critical component of their network architecture.

"While it is positive that companies want to use DNS to protect their increasingly remote workforces, organizations are continuing to suffer the costly impacts of DNS attacks," says Romain Fouchereau, Research Manager European Security at IDC. "As threat actors seek to diversify their toolkits, businesses must continue to be aware of the variety of threats posed, ensuring DNS security is a key priority to preventing these."

"This past year of the pandemic has shown us that DNS must play a role in an effective security system." says Ronan David, VP of Strategy for EfficientIP. "As workers look to more permanently transition to off-premise sites, making use of cloud, IoT, edge and 5G, companies and telecom providers should look to DNS for a proactive security strategy. This will ensure the prevention of network or application downtime as well as protecting organizations from confidential data theft and financial losses."
