An ICMP flood also known as a ping flood is a type of DoS attack that sendsspoofed packets of information that hit every computer in a targeted networ , The "advanced" process signifies sophisticated techniques using malware to exploit vulnerabilities in systems. A Denial-of-Service (DoS) attack is a malicious, targeted attack that floods a network with false requests in order to disrupt business operations. Programs that hide the existence of malware by intercepting (i.e., "Hooking") and modifying operating system API calls that supply system information. While many standard security tools adequately defend against DoS attacks, the distributed nature of DDoS attacks requires a more comprehensive security solution that includes advanced monitoring and detection capabilities, as well as a dedicated threat analysis and remediation team. Popular languages for malicious mobile code include Java, ActiveX, JavaScript, and VBScript. Alternatively, crimeware may steal confidential or sensitive corporate information. APT processes require a high degree of covertness over a long period of time. Application layer attacks are blocked by detection algorithms that can see the signs of malicious traffic before it reaches your network. The success of a digital transformation project depends on employee buy-in. The reason for this is that there is a larger number of machines at the attackers disposal and it becomes difficult for the victim to pinpoint the origin of the attack. Therefore, it is important to understand the threats, vulnerabilities and risks associated with DDoS attacks.
