The use of BGP Flowspec in the protection against DDoS attacksChouk, Wissem January 2019 (has links)
Flowspec is one of the latest DDoS attacksmitigation tools. It relies on BGPv4 to share itsroute specifications. It presents great advantageswhen it comes to effectively mitigate a (D)DoSattack. However, due to the lack of protection andsecurity of BGP, Flowspec presents somevulnerabilities that can be used against the victimto initiate, enhance or continue an attack. An ISP isinterested to include Flowspec in its mitigationtools. In this thesis, we will evaluate the potentialuse of Flowspec by the ISP after taking intoconsideration 3 uses cases where the protocolwould not be able to act as intended. / Flowspec är ett av de senaste verktigen mot DDoS-attacker. Den är beroende av BGPv4 för att dela dess ruttspecifikationer. Det ger stora fördelar när det gäller att effektivt mildra en (D)DoS-attack. På grund av bristen på skydd och säkerhet för BGP presenterar dock Flowspec vissa sårbarheter som kan användas mot offret för att initiera, förbättra eller gå vidare med en attack. En Internetleverantör gynnas av att inkludera Flowspec i dess begränsningsverktyg. I denna avhandling kommer vi att utvärdera den potentiella a n v ä n d n i n g e n a v F l o w s p e c f r å n Internetleverantörens sida efter att ha beaktat 3 användningsfall där protokollet inte skulle kunna fungera som avsett.

Automatická mitigace DDoS útoku / Automation of DDoS Attack MitigationNagy, Peter January 2018 (has links)
The aim of this thesis is automation of DDoS attack mitigation. This thesis provides an overview of GNU/Linux network platforms and different approaches for their configuration. The aim is to select a platform that could be extended to automate DDoS mitigation. DDoS attack types are explained as well. Selected methods for DDoS mitigation are described in more detail such as Remote Triggered Black Hole and BGP Flowspec. Existing tools like DDoS Defender and FastNetMon are used to detect a DDoS attack. NETX was chosen as target implementation platform. To communicate with devices, API or BGP protocol with Flowspec extension are used.
