Presentation given by Roland Dobbins covering our recent draft of use case scenarios for use in DDoS Open Threat Signaling. This presentation was given on Nov. 3rd, 2015 at IETF 94 in Yokohama, Japan.
Hemant Jain outlines 10 DDoS mitigation techniques:
1. SYN proxy screens connection requests and only forwards legitimate ones to prevent SYN floods from overwhelming servers.
2. Connection limiting gives preference to existing connections and limits new requests to temporarily reduce server overload.
3. Aggressive aging removes idle connections from firewalls and servers to free up space in connection tables.
4. Source rate limiting identifies and denies excessive bandwidth to outlier IP addresses launching attacks.

The presentation covers information about basic and advanced ddos attacks; the tools, techniques and methods to perform them and how to prevent them using the methods present in TCP/IP. Given the different network and application protocols for tcp/ip; we tried to describe where ddos attacks are made possible in the communication process . Each attack is seperately analyzed and described and defense technique is described using the same analogy. Our motto: If there is a ddos case, there was a way to defend it.
This document discusses how to launch and defend against DDoS attacks. It explains that DDoS attacks are easy to conduct using tools that allow for spoofing of IP addresses. It also describes how protocols like UDP and DNS amplification attacks can be used to launch large attacks. The document then provides recommendations for how to defend against DDoS attacks, including using a global network with anycast, hiding your origin IP, separating protocols by IP, and working closely with your upstream provider.
DDoS Attack Detection & Mitigation in SDNChao Chen
This document summarizes a presentation on detecting and mitigating distributed denial of service (DDoS) attacks in software-defined networks. It discusses using sFlow and the Floodlight controller to detect common DDoS attack types like ICMP floods, SYN floods, and DNS amplification. An application was developed in Python to classify attacks and push static flow entries to direct attack traffic to the sFlow collector for analysis. The scheme was tested in a Mininet virtual network and shown to successfully mitigate ICMP and SYN flood attacks. Future work includes testing DNS amplification and UDP floods, implementing adaptive sampling rates and thresholds, and designing an unblocking mechanism.
This document discusses the challenges of encrypted traffic inspection and proposes an SSL security service orchestration solution. Some key points:
- 70% of internet traffic is now encrypted, making traditional network security tools like firewalls and antivirus less effective.
- Directly decrypting and inspecting SSL traffic at multiple points (daisy-chaining) has issues like reduced performance, increased complexity, and single points of failure.
- The proposed SSL security service uses a full proxy architecture to classify, decrypt, and re-encrypt SSL traffic dynamically based on policies. It sends traffic through reusable security services and scales dynamically. This provides a centralized solution to inspect encrypted traffic.

PLNOG15 :DDOS Attacks & Collateral Damage. Can we avoid it? Asraf AliMarta Pacyga
This document discusses DDoS attacks, including the types of attacks, their impact on victims, and best practices for network operators. It covers TCP exhaustion attacks, volumetric attacks, reflective amplification attacks that exploit protocols like DNS and NTP, and application layer attacks. These attacks can directly impact content providers and indirectly impact service providers and cloud providers. The document recommends network operators deploy anti-spoofing, scan for and mitigate abusable services, and utilize carrier DDoS protection services to help prevent collateral damage from attacks.
DDoS attacks target companies and institutions that provide online services. They work by overloading servers with traffic from multiple compromised systems known as "bots" or "zombies". Common DDoS attack types include SMURF, TCP SYN/ACK, UDP flood, DNS amplification, and attacks using peer-to-peer networks. Defenses include configuring routers and firewalls to filter unauthorized traffic, limiting response messages, and tracking malicious activity on peer-to-peer networks. As attack methods evolve, continued development of detection and mitigation techniques is needed.

Time-based DDoS Detection and Mitigation for SDN ControllerLippo Group Digital
This document proposes a method to detect and mitigate distributed denial of service (DDoS) attacks on software defined networking (SDN) controllers using time-based characteristics. The method considers not only the malicious packet destination but also the time needed to achieve high traffic rates and periodic attack patterns. The proposed solution architecture monitors packet rates over time windows to detect abnormal traffic increases. Future work includes optimizing detection thresholds, deeper analysis of DDoS attack time patterns, and evaluation of the method's performance in a simulation.
The document provides information about different types of DDoS attacks including DoS, DDoS, DNS reflection, SYN reflection, SMURF, UDP flood, SNMP, NTP, HTTP GET, and HTTP POST attacks. It describes how each attack works and overloads the target system with traffic. Mitigation techniques are also outlined, such as firewalls, rate limiting, authentication, and modifying server configurations.
The document discusses denial of service (DoS) and distributed denial of service (DDoS) attacks. It defines DoS as an attack that renders a system unable to provide normal services by flooding it with traffic. DDoS uses multiple compromised systems to launch a coordinated DoS attack against one or more targets, multiplying the attack effectiveness. Attacks are classified by the system targeted (clients, routers, firewalls, servers), part of the system (hardware, OS, TCP/IP stack), and whether they exploit bugs or just overload resources. Common DDoS tools like Trinoo and TFN are mentioned. Protection from these large-scale attacks remains a challenge.
Distributed Denial of Service or DDoS attacks have been in news a lot lately. This video will explain what those attacks are and provide recommendations on what you can do to prevent or mitigate those attacks on your business or website.
What is DDoS attack? DDoS i.e. Distributed Denial of Service attack overloads the server with a number of requests which results in unavailability of service. It is one of the most powerful cyber attacks. To prevent DDoS attack, every website owner should invest in DDoS protection.

Radware DefenseFlow-The SDN Application That Programs Networks for DoS Security Radware
http://www.radware.com/Products/DefenseFlow/
Learn about the industry's first SDN application that enables network operators to program the network to provide DDoS protection as a native network service.
BGP Flow Specification allows network operators to define and distribute traffic filtering rules via BGP. This helps operators quickly mitigate DDoS attacks by filtering traffic at an upstream level rather than just blackholing entire prefixes. It separates filtering information from routing data using new BGP address families. Validating flow specifications against the best unicast route helps prevent spoofing. Common filtering actions include traffic policing, sampling, and redirection. While some ISPs have begun implementations, widespread adoption is still needed to realize the benefits of centralized DDoS defense using BGP Flow Specification.
This document provides an overview of IP routing and routing protocols. It begins with a high-level explanation of how routing works on the internet through IP addressing and packet forwarding. It then discusses the history of routing, from static routing in early networks to the development of dynamic routing protocols.

IMPROVING DDOS DETECTION IN IOT DEVICESIRJET Journal
This document discusses improving detection of distributed denial of service (DDoS) attacks in internet of things (IoT) devices. It proposes a DDoS detection model that includes decision tree models tailored for different classes of IoT devices. Four classes of devices are defined based on their typical traffic patterns - high, raised, medium, and low consistency. Testing showed the approach can accurately detect DDoS traffic for these device classes, with accuracy ranging from 99.92% to 99.99%. The approach leverages device classes to more precisely identify DDoS traffic.
Service providers are increasingly playing an important role in DDoS mitigation given the growing scale and sophistication of attacks. They have advantages over enterprise solutions due to their global traffic visibility and ability to filter attacks close to the source. As attacks continue rising in scale and evolving tactics, service providers need intelligent mitigation solutions to protect their infrastructure and ensure customer availability. DDoS mitigation is becoming a key differentiator for service providers to provide more value beyond just connectivity.

IRJET- Survey on Mitigation Techniques of Economical Denial of Sustainabi...IRJET Journal
The document summarizes various techniques that have been proposed to mitigate economic denial of sustainability (EDoS) attacks in cloud computing. It describes EDoS-Shield, an early mechanism that uses virtual firewalls and verification nodes to filter requests. Enhanced versions add checks on TTL values and request timestamps. EDoS-Eye uses a game theory approach with honeypots and rate limiting. EDoS-ADS operates in different modes depending on system utilization and uses trust factors to identify suspicious users. Each technique aims to filter attack traffic while minimizing impacts on legitimate users, but they also have drawbacks like increased delays, inability to prevent sophisticated attacks, or potential flooding from redirects.
This document describes a proposed SDN-based scheme for detecting and mitigating distributed denial-of-service (DDoS) attacks mounted by botnets. The scheme involves a DDoS blocking application running on an SDN controller that monitors network traffic flows and detects attacks. When an attack is detected, the application installs rules on SDN switches to block traffic from botnet sources while still allowing legitimate traffic. The target server implements CAPTCHA to differentiate legitimate and bot traffic during attacks. The scheme is implemented using the POX SDN controller and OpenFlow standards and tested on the Mininet emulator.

HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.

3. DOTS WG3
draft-ietf-dots-use-cases-00 Summary
• Provides example use-cases for DOTS (actually, categories).
• All examples can be CE/PE or PE/PE.
• Room for wide variation within each category (see 4.1.1).
• All DOTS communications in each example can be directly
between DOTS servers and DOTS clients, or mediated by
DOTS relays.
• DOTS relays can forward messages between DOTS clients
and servers using either stateless transport, stateful transport,
or a combination of the two.
• DOTS relays can aggregate service requests, status
messages, and responses.
• DOTS relays can filter service requests, status messages, and
responses
4. DOTS WG4
draft-ietf-dots-use-cases-00 Summary (cont.)
• Use-cases in -00 are not exhaustive, are illustrative.
• Use-cases in -00 focus on DDoS mitigation using dedicated
mitigation devices. S/RTBH, flowspec, OpenFlow, etc. can
also be used to leverage network infrastructure for DDoS
mitigation.
• 4.1.1 use-case in this presentation illustrates full DOTS
communications cycle, variants.
• Other use-cases in this presentation are summarized ‘diffs’
illustrating DOTS communications model in widely varying
circumstances.
• Use-cases in this presentation focus on protecting servers
under DDoS attack on destination networks. DOTS can also
be used to suppress attack traffic on origin networks or as it
traverses intermediary networks.
68. DOTS WG68
4.2.1 – Auto-Registration
• Beyond attack mitigation requests, responses, and status
messages, DOTS can also be useful for administrative
tasks.
• Administrative tasks are a significant barrier to effective
DDoS mitigation.
• DOTS clients with appropriate credentials can auto-register
with DOTS servers on upstream mitigation networks.
• This helps with DDoS mitigation service on-boarding,
moves/adds/changes.
69. DOTS WG69
4.2.2 – Automatic Provisioning of DDoS Countermeasures
• DDoS countermeasure provisioning today is a largely
manual process, errors and inefficiency can be problematic.
• This can lead to inadequately-provisioned DDoS mitigation
services which often are not optimized for the assets under
DDoS protection. Mitigation rapidity, efficacy suffers.
• On-boarding organizations during an attack – an all-too-
common situation – can be very challenging.
• The ‘self-descriptive’ nature of DOTS registration and
mitigation status requests can be leveraged to automate the
countermeasure selection, provisioning, and tuning process.
• Mitigation efficacy feedback from DOTS clients to DOTS
servers during an attack can be leveraged for real-time
mitigation tuning and optimization.
70. DOTS WG70
4.2.3 – Informational DDoS Attack Notification to Third Parties
• In addition to service requests from organizations under
attack to upstream mitigators, DOTS can be used to send
DDoS attack notification and status messages to interested
and authorized third parties.
• It may be beneficial in some circumstances to automatically
provide attack notifications and status messages econdary
or tertiary ‘backup’ mitigation providers, security
researchers, vendors, law enforcement agencies, regulatory
agencies, etc.
• Any such sharing of information with third parties should
only take place in accordance with all relevant laws,
regulations, contractual obligations, privacy and
confidentiality agreements.
72. DOTS WG72
To-Do List for draft-dots-ietf-use-cases-01
• Fix typos (doh!).
• Remove duplicative verbiage.
• Wordsmith phrasing for clarity.
• Present use-cases via ‘diffs’ – i.e., refer to commonalities
with other use-cases, emphasize specific factors unique to
each use-case.
• Reconcile definitions of terminology with dots-ietf-
requirements draft.
• Add use-cases illustrating suppression of DDoS attack traffic
on origin networks, filtering on intermediate networks.
• Add use-cases illustrating specific PE-PE scenarios (e.g.,
‘overflow’ requests for additional DDoS mitigation capacity,
etc.).
73. DOTS WG73
Request for Feedback from WG Participants
• What should we add?
• What should we remove?
• What should we change?
• Should we include variations (via ‘diffs’)
on each use-case similar to what was
done with 4.1.1 in this presentation?
• Other input?
