1 Traffic Diversion Techniques for DDoS Mitigation using BGP Flowspec Leonardo Serodio May 2013

2 Distributed Denial of Service (DDoS) Attacks DDoS attack traffic consumes SP network capacity DDoS attack traffic saturates inline security devices Bots Victim Firewall IPS Internet Service Provider Network Enterprise or IDC DDoS attacks launched from compromised systems (bots) DDoS attack traffic targets applications & services 2

3 Cloud-based DDoS Defense with RTBH BGP Announcement Originated by the Victim D/RTBH - All traffic to the victim is discarded! Remotely Trigered Black Hole Filtering at Peer SP edge Victim initiates BGP announcement Victim RTBH RTBH Firewall IPS Good traffic Attack traffic Internet BGP Announcement Service Provider Network Enterprise or IDC BGP Prefix with next-hop set to predefined black-hole route. Fourth most used tool to mitigate DDoS attacks [5] RFCs: RFC 3882, RFC 5635 (includes D/RTBH and S/RTBH) 3

4 Cloud-based DDoS Defense with RTBH BGP Announcement Originated by the SP D/RTBH - All traffic to the victim is discarded! Remotely Trigered Black Hole Filtering at SP edge Victim RTBH RTBH Firewall IPS Internet Good traffic Attack traffic BGP Announcement Service Provider Network Enterprise or IDC BGP Prefix with next-hop set to predefined black-hole route. 4

5 BGP Flow Specification BGP Flowspec defines a new BGP Network Layer Reachability Information (NLRI) format used to distribute traffic flow specification rules. NLRI (AFI=1, SAFI=133): IPv4 unicast filtering NLRI (AFI=1, SAFI=134): BGP/MPLS VPN filtering Specified by RFC 5575 [1], extended to IPv6 in [2] Main application today is to automate the distribution of traffic filter lists to routers for the mitigation of DDoS attacks. Selectively drop traffic flows based on L3/L4 information. Intelligent control platform builds filter rules to drop harmful traffic, encodes them as BGP flowspec routes and advertises them to BGP peers. 5

6 BGP Flow Specification The Flow specification can match on the following criteria: Source / Destination Prefix IP Protocol (UDP, TCP, ICMP, etc.) Source and/or Destination Port ICMP Type and Code TCP Flags Packet Length DSCP (Diffserv Code Point) Fragment (DF, IsF, FF, LF) Actions defined using Extended Communities: 0x8006: traffic-rate (rate 0 discards all traffic for the flow) 0x8007: traffic-action (sample) 0x8008: redirect to VRF 0x8009: traffic-marking (DSCP value ) 6

7 BGP Flow Specification Why Use It for ACLs? ACLs are still the single most widely used tool to mitigate DDoS attacks [5]. But ACLs are demanding in configuration & maintenance. BGP Flowspec leverages the BGP Control Plane to simplify the distribution of ACLs, greatly improving operations: Inject new filter rules to all routers simultaneously without changing router configuration. Reuse existing BGP operational knowledge and best practices. Control policy propagation via BGP Communities. Improve response time to mitigate DDoS attacks. Route validation performed for ebgp sessions, see draft [3] for revised validation procedure for ibgp sessions. 7

8 Cloud-based DDoS Defense with BGP Flowspec Inter-domain flowspec injection Volumetric attack traffic removed at ISP network edge Only clean traffic delivered to enterprise/idc Flowspec Victim Flowspec Flowspec Firewall IPS Internet Service Provider Network Enterprise or IDC Good traffic Attack traffic Flowspec Flowspec mitigation controlled by ISP customer under attack 8

9 Cloud-based DDoS Defense with BGP Flowspec Intra-domain flowspec injection Volumetric attack traffic removed at ISP network edge Only clean traffic delivered to enterprise/idc Flowspec Victim Flowspec Flowspec Internet SOC Service Provider Network Firewall IPS Enterprise or IDC Good traffic Attack traffic Flowspec Flowspec mitigation controlled by the ISP or ISP customer via Portal 9

10 BGP Flow Specification Vendors & Users Router vendors supporting BGP Flowspec: Alcatel-Lucent 7750 SROS 9.0R1 Juniper JunOS 7.3 DDoS mitigation vendors: Arbor Peakflow SP 3.5 BGP Tools: ExaBGP Injector [7] Users: North America: TW Telecom (TWTC) [6], other Tier 1, Tier 2 Europe: Tier 1, Tier 2 Latin America & Caribbean: RNP (Brasil) [8] Flowspec itself is the 8 th most used tool to mitigate attacks [5] 10

12 DDoS Protection with Mitigation Appliance (IDMS) Surgical Mitigation Traffic anomaly is scrubbed by a DPI-capable mitigation appliance that surgically removes the attack traffic only. Mitigation appliances are also known as Intelligent DDoS Mitigation Systems (IDMS). IDMS are the second most used tool for DDoS protection [5]. Able to mitigate complex, application-layer DDoS attacks without completing the attack. Typically a shared resource in the network infrastructure. Traffic anomalies need to be redirected in the network to go through the IDMS before reaching the intended destination: - Traffic Diversion or Offramping - Traffic Reinjection or Onramping 12

13 IDMS-based DDoS Mitigation Terminology Diversion or Offramping: rerouting of traffic destined to the victim to the DDoS mitigation appliance for scrubbing. Reinjection or Onramping: redirection of scrubbed (clean) traffic back to its intended destination. Typically, traffic diversion takes place through more specific BGP prefix announcements (victim addresses), usually in the GRT (called diversion/offramp route): Easier to control & manipulate routes (NH, Communities) Can be signaled across AS boundaries if required Traffic Reinjection usually requires tunneling or an alternate routing domain (VRF) to get clean traffic back to its intended destination without looping. 13

14 IDMS-based DDoS Mitigation Scrubbing Center Design Traffic Diversion Scrubbing Center IDMS (Mitigation Appliance) Scrubbed Traffic Reinjection Internet Victim Firewall IPS Good traffic Attack traffic BGP Prefix Diversion Diversion Prefixes (BGP) Detection & Control Internet GRE Tunnel or VRF (dotted yellow line) Enterprise or IDC 14

16 Traffic Diversion with BGP Prefixes The Good & The Bad Real mitigation of DNS attack 16

17 DDoS Mitigation Appliance Surgical Diversion Using BGP Flowspec Redirect to VRF Action Traffic diversion using a VRF (subset of all traffic to victim). Scrubbing Center Mitigation Appliance Traffic Reinjection Internet Victim Firewall IPS BGP Flowspec filter to redirect only specified traffic Detection & Control Enterprise or IDC Dirty VRF Good traffic Attack traffic BGP Flowspec Diversion Internet 17

18 Surgical Diversion Using BGP Flowspec Optimized Design & Operation No changes to the Global Routing Table (GRT) Diversion performed by Flowspec NLRI Flowspec filter Action configured to Redirect to VRF Extended Community 0x8008. Less intrusive to the routing system No need for a tunneling design for reinjection/onramping Clean traffic can simply be sent back to the GRT More granular control of diverted traffic Allows for the redirection of only a subset of the traffic to the victim: specific protocols, ports, source prefix, destination prefix Less traffic overhead for Mitigation Appliance to deal with 18

19 Surgical Diversion Using BGP Flowspec Enabling New Workflows Facilitates the implementation of new mitigation workflows for demanding use cases: Always on Mitigations for critical resources: HTTPS traffic only (normal web traffic follows on-demand mitigation model) ICMP & UDP traffic Victims with very large traffic volume Divert just traffic from a certain block, or geographical region (based on IP Location) 19

20 Public Facing Servers Surgical Diversion for Data Centers Optimizing the Mitigation of Application-Layer DDoS Attacks On-demand or continuous mitigation of selective traffic Benefits of continuous DPI traffic scrubbing without the risks and demands of in-line deployments. Legitimate Users Flowspec GRT Firewall / IPS / WAF Attackers VRF I D M S Backbone / Internet Data Center Network 20

21 BGP Flowspec Diversion Work in Progress New Redirect to IP Next-Hop Flowspec Action Described in draft-simpson-idr-flowspec-redirect-02.txt [4] New Extended Community value 0x0800 Enables BGP flowspec redirection using encapsulations other than VRFs, such as GRE or MPLS tunnels. Scrubbing Center Mitigation Appliance Victim MPLS or GRE Tunnel Enterprise or IDC 21

22 Summary Surgical Diversion Benefits Using BGP Flowspec: Greatly simplifies traffic diversion design and operation: Less intrusive to the routing system no changes to the Global Routing Table (GRT). On the reinjection side, there is no need to use tunneling (GRE) or VRF designs. Optimizes the benefits of a DDoS Mitigation Appliance ( surgical mitigation ) with precise diversion: Allows for a better optimization of the shared mitigation capacity of the mitigation appliance. Addresses demanding mitigation use cases. On-demand & continuous scrubbing per application or other criteria. 22
