  1. 1. A Prevention Technique for DDoS Attacks in SDN using Ryu Controller Application

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Yashwanth Venkata Sai Kumar Adabala; Lakshmi Venkata Raghava Sudheer Devanaboina; [2024]
    Nyckelord :Software Defined Networking; SDN; IP Spoofing; Flooding; DDoS Attacks; Mininet; Snort IDS; Network Security;

    Sammanfattning : Software Defined Networking (SDN) modernizes network control, offering streamlined management. However, its centralized structure makes it more vulnerable to distributed Denial of Service (DDoS) attacks, posing serious threats to network stability. LÄS MER

  3. 2. DDoS Defense: Next-Generation Firewall versus Traditional Firewall

    M1-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :William Andell; Filip Eskel; [2023]
    Nyckelord :Brandväggar; jämförelse;

    Sammanfattning : Syftet med detta examensarbete var att utvärdera hur två olika brandväggar, en nästa generationens brandvägg och en traditionell brandvägg, hanterade en mindre distribuerad denial of service-attack. Enheterna kördes så nära dess förkonfiguration som möjligt. Testningengenomfördes i en kontrollerad labbmiljö på Högskolan Väst. LÄS MER
