Preventing Ddos Attacks PowerPoint PPT Presentations

A DDoS attack is a malicious attempt to disrupt the normal functioning of a network resource by making it unavailable to its intended users. A DDoS attack is significantly different from a denial-of-service (DoS) attack, since DDoS attacks use many computers and internet connections, often distributed globally, to what is called as the botnet. Three types of system resources will be targeted: computational resources (bandwidth and processor time), configuration information (routing information), and state information.

DoS Attacks..by Aleksei Zaitsenkov OUTLINE DoS Attacks ... People are talking about the Internet as though it is going to change the world.

Cybersecurity consists of two terms; "Cyber" means relating to the characteristic of computers, information technology, etc., and "Security" means protection or prevention. Thus, Cybersecurity is the term used to protect the systems connected to the internet, such as hardware, software, and data, from cyber threats. This practice of protecting these devices and especially data is done by individuals and enterprises to prevent unauthorized access for attackers trying to enter into the system. A good cybersecurity strategy adopted by the organization can prevent the systems from malicious attacks and stop further damage to the company and its reputation.

http://www.prolexic.com/services-dos-and-ddos-mitigation.html Can automated DDoS mitigation appliances alone stop today’s large, brute force DDoS attacks from bringing down your website? The answer is no. Attackers can overwhelm and sidestep static devices in several ways. In Prolexic’s experience, all the tools available today to fight against DDoS attacks are missing the most important part of the solution – the experience of an expert security engineer. In this excerpt from their DDoS protection planning white paper, Prolexic explains why you need human security expertise in today’s threat landscape.
