As the vast majority of businesses have shifted to remote work during the COVID-19 pandemic, reliance on network connectivity via virtual private networks (VPNs) has dramatically increased. Employees have become increasingly dependent on communication and collaboration tools, as well as access to internal applications within their company networks. This rapidly expanding VPN use is accompanied by the specter of growing threats from distributed denial of service (DDoS) attacks, which hold the potential to cripple these vital lines of connectivity and grind businesses to a halt—not to mention irreparably harm their reputations.
A large telecommunications service provider in Western Europe that provides bundled communication services to its enterprise customers –with security a major component—became increasingly concerned about the threat landscape and potential impact to customers. These attacks are frequently a dynamic combination of volumetric, TCP state exhaustion, and application-layer attack vectors. Because of the complexity of these attacks, the telecom provider needed a multilayer approach to threat management and mitigation. To alleviate customer concerns and improve its security defenses against DDoS attacks, the provider turned to NETSCOUT.
