Distributed Denial of Service attacks represent unique threats to the data center, and as their strength and scope continue to expand, businesses of all sizes need to align their systems properly to safeguard critical data.
Throughout 2010, there was a sharp rise in both the scale and frequency of DDoS attacks across the world, according to research from Arbor Networks. And as Arbor analysts predicted, the cost-effective hacking tool has gained wider popularity within the cybercriminal community in 2011 as groups such as LulzSec and Anonymous continue to stage online protests.
Earlier this year, a massive DDoS attack on the Sony Playstation network rendered more than 100 million user accounts temporarily inaccessible. And just this week, Australian web host and domain reseller Netregistry had its data security strategies tested by a DDoS threat that may have affected as many as 70,000 websites, according to ZDNet.
According to Data Center Dynamics, the threat first compromises a network's firewall as hackers attempt to overwhelm its finite resources. This can quickly lead to lost traffic, frozen devices and full network outages. Hackers may also be shifting focus toward the application layer of data centers to cause even greater damage, according to the source.
To protect networks from DDoS attacks, businesses may be best served by a layered approach. According to the news provider, perimeter defenses, application layer safeguards and effective monitoring may be the answer. These exhaustive efforts may be asking a lot of an enterprise IT department, but the costs of inadequate preparation could be far worse.
Unfortunately for small- and medium-sized businesses, DDoS threats are not localized to only high-profile, big business targets, and it can be particularly challenging to design a complete data security strategy on a limited budget. But for SMBs relying on a predominantly ecommerce business model, the consequences of a successful DDoS attack can be catastrophic and are too significant to ignore.
According to IT Business Edge, small-and medium-sized business will need smart strategies to protect critical data with their limited IT resources. The first step toward improved Internet security will include performance monitoring. These data center tools will allow IT managers to observe and establish a base level of network performance. Monitoring and tracing the root of sudden network slowdown may be instrumental when attempting to stop threats before they start. Keeping up-to-date with operating system and software patches will also help eliminate unnecessary loopholes.
