Why are application-layer DDoS attacks on the rise? However, this year’s report indicated a rise in new targets such as email and SIP/VoIP applications.

As in years past, top targeted applications were HTTP, HTTPS, and DNS.

For example, in 2017, 32% of all DDoS attacks were application-layer attacks vs. The number of application-layer attacks is increasing. TCP-state exhaustion attacks are designed to take out, what’s in many cases, an organization’s first line of defense meaning their firewalls, IPS, etc.Īpplication-layer attacks are designed to target and exhaust resources in application servers using commands like HTTP GET, PUT etc. According to the WISR, volumetric attacks make up 52% of all DDoS attacks – interestingly this is a drop from 60% in 2016. These types of attacks can be quite large (up to 600 Gbps). Volumetric attacks are designed to saturate bandwidth, internet facing router interfaces, circuits etc. And according to NETSCOUT's annual Worldwide Infrastructure Security Report (WISR), application-layer attacks are on the rise.Īs the graphic above shows, each attack vector has a specific goal in mind. The modern-day DDoS attack is complex as it typically executes a dynamic combination of Volumetric, TCP-State Exhaustion and Application-layer attack vectors. What is an application-layer DDoS attack? A "service unavailable" notification could be the result of an application-layer DDoS attack targeting your servers and critical infrastructure.
