ICMP flood
An attacker floods a victim’s network with a large number of ICMP (Internet Control Message Protocol) packets, which can cause the network to become unresponsive.
SYN flood
An attacker floods a victim’s network with a large number of SYN (synchronization) packets, which can cause the network to become unresponsive.
HTTP flood
An attacker floods a victim’s website with a large number of HTTP requests, overwhelming the server and causing it to become unavailable.
DNS amplification
An attacker uses a botnet to flood a DNS (Domain Name System) server with requests, amplifying the traffic and causing the server to become unresponsive.
DDoS attacks are a serious threat to organizational security, as they can result in lost revenue, damaged reputation, and lost productivity. Therefore, it is important to have a DDoS mitigation strategy in place, such as using a content delivery network (CDN), having backup servers, and using a cloud-based security service.
Social engineering: Definition and examples
Social engineering is a type of cyber attack in which an attacker manipulates a person’s behavior or emotions in order to gain access to sensitive information or to trick them into performing an action. Social engineering attacks can take many forms, but they all involve exploiting human psychology rather than technical vulnerabilities. Some examples of social engineering attacks include:
Pretexting
An attacker creates a fake scenario or identity in order to gain a victim’s trust and persuade them to reveal sensitive information or perform an action.
Phishing
An attacker sends a fraudulent email or message that appears to be from a legitimate source, in order to trick the victim into revealing sensitive information or downloading malware.
Baiting
An attacker leaves a physical or digital “bait”, such as a USB drive or fake advertisement, in order to trick the victim into taking an action that compromises their security.
Tailgating
An attacker follows an authorized person into a secure area, without their knowledge, in order to gain access to sensitive information or equipment.
Social engineering attacks are a serious threat to personal and organizational security, as they can result in stolen passwords, financial loss, and identity theft. Therefore, it is important to be aware of the tactics used in social engineering attacks, to be cautious of unsolicited requests for sensitive information, and to verify the authenticity of requests before providing any information or performing any actions.
