The terms ingress and egress mean, respectively, the acts of entering and exiting. In an interconnected network of networks, such as the Internet, what leaves (egresses) one network will enter (ingress) another. It is extremely important to clearly define the location where the filtering is done with respect to the network whose traffic is being [...]
IP spoofing is not necessary for a successful DDoS attack, since the attacker can exhaust the victim’s resources with a sufficiently large packet flood, regardless of the validity of source addresses. However, some DDoS attacks do use IP spoofing for several reasons. 1. Hiding the location of agent machines. In single-point DoS attacks, spoofing was [...]
One tactic used in malicious attacks, particularly in DDoS, is IP spoofing. In normal IP communications, the header field contains the source IP address and the destination address as set by the default network socket operations. IP spoofing occurs when a malicious program creates its own packets and does not set the true source IP [...]
We had discussed it earlier about the distributed denial of services (DDoS) impact in previous articles, lets get to know more deeper about its primary target. Creating a DoS effect is all about breaking things or making them fail. There are many ways to make something fail, and often multiple vulnerabilities will exist in a [...]
Commonly attackers using using distributed techniques in order to spread their worm, but it’s also poses a challenge for an attacker itself. For example, imagine that a DoS attack based on pure flooding originates at a single machine with a 10-Mbps link and is directed toward a victim machine that has a 100-Mbps link. In [...]
