ORGANISATIONS that now depend on the use of Internet connectivity for the supply of services and products for its operation has been advised to ensure that they have the right level of protection for their Internet services.
The trend of such internet attack is known Distributed Denial of Service (DDoS): an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources, which are often infected with a Trojan.
Account Manager, Sub-Sahara Africa for Arbor Network, Mr. Jaco Du Toit told TechnologyMirror at the just concluded NigCom ICT confront held in Lagos, South West Nigeria that the threat posed by DDoS attacks to Internet service availability and business is significant.
According to him, the on-going trend of DDoS attacks is increasing in size, complexity and frequency combined with the change in the motivations behind attacks has seen more and more organisations targeted.
He observed that reliance on Internet connectivity for the supply of services and products within organisations has never been so great noting that the costs of being the victim of a DDoS attack are becoming more widely appreciated.
He therefore urged organisations to ensure that they have the right level of protection for their Internet services stressing, “Organisations that are reliant on the Internet for their business should ensure that they have hybrid services in place which can protect them pro-actively from the DDoS threat.”
Arbor, which is the security division of NETSCOUT was at the two day conference and exhibition to showcase some of its latest IT security skills.
Toit said protecting Internet Service availability from threats such as DDoS has become critical as more and more organisations have become reliant on their Internet connectivity for their primary revenue stream whether from e-commerce, banking or gaming.
In a document he made available to TechnologyMirror, he said “Understanding what DDoS attacks are, and the ways in which different attack vectors can impact our infrastructure and services, will enable to use to determine which characteristics are most important when selecting a solution for our organisation.”
He explained that it is a simple fact that more and more organisations have become reliant on Internet connectivity for their day-to-day business needs but that “if Internet services are interrupted there is a business cost, and that cost can be very significant.”
He stated: “A DoS attack is simply an attempt by an attacker to exhaust the resources available to a network, application or service so that genuine users cannot gain access.
The majority of attacks that we see today are what we call Distributed DoS (DDoS) attacks – these are just DoS attacks launched from multiple different hosts simultaneously; and, in the case of a botnet, we could be talking about 10s, 100s or even 1000s of machines.”
Toit disclosed that the increased availability of (relatively) sophisticated attack tools, and the growth of ideologically motivated attacks, has broadened the spread of organisations being targeted.
Quoting a North America March 2011 survey, he said 63% of respondents had seen one or more attack against their business in the previous year, with 11% seeing six or more attacks adding that 46% of respondents indicated that they had seen outages of 5 or more hours, with 23% seeing outages of 12 or more hours.
