全面解析這兩種網路攻擊的特性與應對方式 什麼是DDoS攻擊？ DDoS（Distributed Denial of Service，分散式阻斷服務攻擊）是一種常見的網路攻擊，攻擊者透過控制大量的僵屍網絡設備，向目標伺服器發送大量流量，導致伺服器過載或無法提供正常服務。全面解析這兩種網路攻擊的特性與應對方式 什麼是DDoS攻擊？ DDoS（Distributed Denial of Service，分散式阻斷服務攻擊）是一種常見的網路攻擊，攻擊者透過控制大量的僵屍網絡設備，向目標伺服器發送大量流量，導致伺服器過載或無法提供正常服務。

DDoS攻擊的主要類型
1. 流量型攻擊
流量型攻擊的目的是通過產生巨大的網絡流量來耗盡目標的頻寬，常見的攻擊包括：
UDP Flood：向目標伺服器發送大量的UDP數據包，迫使其無法處理正常流量。
ICMP Flood：利用Ping命令發送大量ICMP Echo請求，消耗目標的頻寬和處理能力。
特徵：大流量、高頻率數據包，目標是阻塞網絡頻寬。
2. 協議型攻擊
協議型攻擊針對伺服器的協議棧或操作邏輯進行攻擊，目的是耗盡其計算資源。
SYN Flood：利用TCP握手的漏洞，發送大量SYN請求但不完成握手，佔用伺服器資源。
Ping of Death：發送異常大的數據包，導致目標伺服器無法處理。
Smurf Attack：偽造源地址的ICMP數據包，讓伺服器處理無效的請求。
特徵：針對網絡協議設計的漏洞，攻擊伺服器的邏輯處理能力。
