The size, frequency and complexity of Distributed Denial of Services (DDoS) attacks is increasing. According to figures from Arbor’s ATLAS network, in the Middle East, by the end of 2013, the average attack size was 2.8 Gbps, higher than the global average of 2.3 Gbps. Because of this, security and availability are now among the top requirements of IT departments in businesses across the region. Unfortunately, when it comes to today’s range of sophisticated DDoS attacks, traditional security products, such as firewalls or intrusion prevention systems, are proving to be inadequate.
