Sometimes keeping it simple can be stupid

Technology is often praised when it is simple. However, this virtue shouldn't necessarily be held to the security industry. When a simply designed network is penetrated by a malicious user, the entire network can be easily taken down. By designing a complex system, more stability can be achieved through redundancy and fault tolerance.

That being said, an auditor should understand the reasoning behind configurations and if something appears unusual, it is important for that administrator to investigate why it was designed in that manner. While a complex system can offer more stability, it's important that it remain logical and fully understood by internal audiences.

2014 is shaping up to be the year of the distributed denial of service (DDoS) attack. A DDoS attack is when malicious codes infect a computer, triggering mass attacks against targeted websites, making them inaccessible to regular users. If the attack is strong enough to affect network equipment at the perimeter of the target (e.g., firewalls), the entire network of the service under attack may stop responding.

A DDoS attack can be incredibly difficult to defend against despite the fact that it isn't considered very sophisticated. Many DDoS attacks succeed because organizations do not understand how to protect against them, and have not made it a priority. Security managers are generally well versed in choosing the most fitting technologies to counter threats such as intrusions, worms and Web application exploitations. But there is a common misconception among the security community that these same technologies can also be relied upon for DDoS protection. Perhaps the biggest misconception tied to DDoS attacks is that installing and running a single protective software on a well-known Internet platform or host is sufficient to keep the organization safe. This has been disproved in spades as recent attacks to major websites have rocked the IT community.

In this slideshow, Zensar Technologies has outlined the steps an organization can take in order to better protect itself as DDoS attacks continue to gain traction. These steps include a combination of anti-DDoS technology and anti-DDoS emergency response services.  

Zensar Technologies delivers comprehensive services in mission-critical applications, enterprise applications, e-business, business process management and knowledge services.
