DDoS attacks are executed against websites and networks of selected victims. A number of vendors offer "DDoS-resistant" hosting services, mostly based on techniques similar to content delivery networks. Distribution avoids a single point of congestion and prevents the DDoS attack from concentrating on a single target.
Diagram of a DDoS attack. Note how multiple computers are attacking a single computer. In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network.
A cyber countermeasure is defined as an action, process, technology, device, or system that serves to prevent or mitigate the effects of a cyber attack against a victim, computer, server, network or associated device. [4] Recently there has been an increase in the number of international cyber attacks.
In the cybersecurity arena, active defense may mean "asymmetric defenses," namely defenses that increase costs to cyber-adversaries by reducing costs to cyber-defenders. [1] For example, an active defense data protection strategy leverages dynamic data movement, distribution, and re-encryption to make data harder to attack, steal, or destroy. [2]
A cybersecurity regulation comprises directives that safeguard information technology and computer systems with the purpose of forcing companies and organizations to protect their systems and information from cyberattacks like viruses, worms, Trojan horses, phishing, denial of service (DOS) attacks, unauthorized access (stealing intellectual property or confidential information) and control ...
Active defense is a strategy performing security measures attacking the potential intruders. The strategy is based on the assumption that a potential intruder under attack has fewer abilities. Examples of this strategy include creating and using lists of trusted networks, devices, and applications, blocking untrusted addresses, and vendor ...
Proactive cyber defense, means acting in anticipation to oppose an attack through cyber and cognitive domains. [1] Proactive cyber defense can be understood as options between offensive and defensive measures. It includes interdicting, disrupting or deterring an attack or a threat's preparation to attack, either pre-emptively or in self-defence.
This type of attack generates a large volume of data to deliberately consume limited resources such as bandwidth, CPU cycles, and memory blocks. Distributed Denial of Service (DDoS): This kind of attack is a particular case of DoS where a large number of systems are compromised and used as source or traffic on a synchronized attack. In this ...
