The Role of Big Data
– Big Data is a field devoted to analyzing, processing, and storage of extensive collections of data that continually originate from disparate sources. Consequently, Big Data solutions and practices are typically required when more than traditional data analysis, processing, and storage technologies and techniques are needed. Mainly, Big Data addresses distinct requirements, such as combining multiple unrelated datasets, processing large amounts of unstructured data, and harvesting hidden information time-sensitively.
– IPFIX, short for IP Flow Information Export, is a protocol that allows for the collection and export of flow records from network devices. It provides valuable insights into network traffic patterns, including source and destination IP addresses, ports, and protocols. By capturing and analyzing IPFIX data, organizations gain a comprehensive understanding of their network infrastructure and can make data-driven decisions to optimize performance and security.
– The true power of IPFIX lies in its ability to handle big data. With the exponential growth of network traffic, traditional analysis methods fall short. IPFIX big data solutions, on the other hand, leverage advanced analytics and machine learning algorithms to process massive amounts of flow data in real time. This enables network administrators to identify anomalies, detect security threats, and troubleshoot performance issues with unmatched precision and speed.
Use Cases of IPFIX Big Data
1. Network Performance Optimization: By analyzing IPFIX data, organizations can identify bandwidth bottlenecks, optimize network configurations, and ensure efficient resource allocation. This leads to enhanced network performance, reduced latency, and improved user experience.
2. Security Threat Detection: With the help of IPFIX big data analytics, organizations can detect and mitigate security threats in real-time.

3. Capacity Planning and Traffic Engineering: IPFIX big data offers valuable insights into network traffic patterns, allowing organizations to plan for future capacity needs. Organizations can ensure smooth operations and avoid costly downtime by analyzing historical data, predicting traffic trends, and optimizing network infrastructure.
IP Flow Information Export
a) IPFIX is overseen by the Internet Engineering Task Force (IETF). Flow information can be exported from routers, switches, firewalls, and other infrastructure devices using IPFIX. Exporters and collectors use IPFIX to format and transfer flow information. Several RFCs, including 7011 through 7015 and RFC 503, describe IPFIX. Version 9 of NetFlow is the basis and primary reference for IPFIX. IPFIX is essentially the same as NetFlow Version 9, except for a few terminologies.
b) Push protocols are considered IPFIX protocols. IPFIX-enabled devices automatically send IPFIX messages to configured collectors (receivers) without user input. In most cases, the sender orchestrates IPFIX data messages. To construct these flow data messages, IPFIX introduces the concept of templates. User-defined data types can also be used in IPFIX messages. IPFIX prefers Stream Control Transmission Protocol (SCTP) as the transport layer protocol; however, Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) can also be used.
c) UDP messages are usually used to export Cisco NetFlow records. On the sending device, the IP address of the NetFlow collector and the destination UDP port must be configured. The NetFlow standard does not specify a specific NetFlow listening port (RFC 3954). In addition to UDP port 2055, NetFlow can use ports such as 9555 or 9995, 9025, and 9026. IPFIX uses UDP port 4739 by default.
Attacking Tools are Readily Available
Attacker tools are readily available, making DDoS defense much harder than attack. It’s hard to blame anyone; the ISP is just transiting traffic, and end users don’t know if they are compromised and part of a BotNet farm. There is no service of abuse or license for the Internet, making tracking and detection between independent service provider locations difficult. Recently, there has been a shift in application footprints. We now have multi-tiered applications dispersed across various sites, all requiring cross-communication.
- New Attack Surface
New application architecture results in new attacks, and with any application segment, you are only as strong as the weakest link, requiring a new set of network visibility. That can help you correlate disparate data points. The birth of the cloud and new technologies increased the attack surface, making quick and accurate DDoS detection using tools such as IPFIX Big data an enchantment to other DDoS solutions such as BGP Flowspec.
- The Ability to Stop DDoS
Companies require mechanisms to stop and slow down DDoS attacks. The IETF introduced best practices with BCP38, and service providers started incorporating ingress filtering into their designs and cross-checking incoming frames. However, ISPs are not forced by contract to implement these features. The only way to adequately mitigate DDoS attacks is adequate detection. How long should this take? What timeframe is acceptable?
All this depends on the traffic analysis solution you have in place. Initially, traffic analysis began monitoring up/down interfaces with introductory statistics. They then moved to Syslog servers and single source basic flow capturing. We need a system that captures enriched flow data and groups infrastructure and application information together. Enriching data from all elements allows the network and its traffic to be viewed as one holistic entity.

Challenges and Considerations:
Implementing IPFIX Big Data comes with its own set of challenges. Organizations must ensure they have sufficient storage and processing capabilities to handle large volumes of data. They must also consider privacy and security concerns when collecting and storing IPFIX data. Additionally, the complexity of IPFIX data requires specialized skills and tools for practical analysis and interpretation.
IPFIX Big Data: Enhanced Data Sources
DDoS traffic analysis solutions extract various types of flow data from network devices. The flow record consists of fields from multiple data types, including NetFlow, IPFIX, and sFlow. In addition, DDoS Big Data solutions can enrich records at the ingest layer by performing a lookup of the source and destination in the flow, BGP table, and GeoIP database. These values are added as volumes and fields stored with the original flow. The extra information lets administrators slice the traffic at ingesting, enabling a fantastic multi-dimensional view of network traffic.
Tools like sFlOW and IPFIX variants like IPFIX BGP are critical in DDoS detection. Classic flow fields based on 5-tuples include IP address and source/destination port numbers, which are later expanded to include MAC address, MPLS, and application schematics like URLs, HTTP host headers, DNS queries, and responses.
The availability of advanced fields enables the detection of sophisticated attacks higher up the protocol stack. For example, access to the HTTP host header for each request allows precise identification down to the URL
A key point: Different attacking vectors.
Not all DDoS attacks and DNS reflection attacks are easily detected. Volumetric attacks, such as SynFlood, are more accessible to catch than SlowLoris and RUDY attacks. Layer 7 attacks usually don’t exceed the packet/sec threshold, a standard parameter for detecting volumetric-based attacks.
To combat this, we must go deeper than the standard 5-tuple with augmented flows. Augmented flows contain additional fields to include a variety of advanced metrics such as connection counts, congestion windows, and TCP RTT. Traditional flow data does not provide this level of detailed information.
Data source variations
Netflow and IPFIX, flow record creation, is based on packets sharing the same fields. Flow state is held, hitting system resources. To save system resources, flows are exported at predefined times. As a result, traffic measurement is accurate, but it might not hit the detector for up to one minute.
sFlow sends packet samples every 1 in N, streaming flows as soon as they are prepared. sFlOW draws fewer system resources than its Netflow counterpart. It is considered faster and has better accuracy, meaning it’s an excellent tool for DDoS detection.
sFlow is better at carrying the source MAC address than NetFlow and IPFIX. With NetFlow and IPFIX, the source MAC is possible but not usually implemented by all vendors. NetFlow is useful for some requirements, while IPFIX and sFlow are for others.
To get all the possible knobs, it’s better to extract them from all data sources and combine them into one database that can easily be viewed with a single portal. Combining all data sources into one unified store makes the protocol type less relevant.
IPFIX BGP
DDoS solution: Irregularities with ASN Information
DDoS solutions can peer EBGP with customers by giving them a copy of the BGP table. Customer route updates are reflected through the standard BGP propagation procedure. It’s a non-intrusive peering agreement; BGP’s next hops are not altered, meaning customers’ data plane traffic flows as usual. The contents of the BGP table provide access to customers’ control plane information, enabling complete visibility of the data source and destination.
The manual approach with BGP can be cumbersome. BGP offers a string of information about DDoS sources and destinations, but it can be hard to craft regular expressions to extract this information. Not everyone can craft regular expressions, a skill for senior engineers.
Netflow and BGP
Netflow does provide some BGP ASN information, but you only have access to the source and destination of the Peer or Origin ASN. Some high-end platforms do both, but it’s restricted to specific devices and vendor discretion. NetFlow should not hold all BGP-type information; this would be a suboptimal solution.
Also, Netflow does have drawbacks and inaccuracies when determining the source ASN. The destination ASN is never usually a problem. The BGP process/daemon performs a REVERSE BGP Lookup to determine the source ASN and populate the FIB.
However, this type of BGP lookup does not guarantee the correctness of results. A REVERSE BGP Lookup primarily determines how to route back to the source, but this does not correlate with how the source may route to you.
Most networks are asymmetric, meaning the source-destination path differs from the reverse direction. An IP packet traversing from source A to destination B will take a different return path. Due to the shared nature of asymmetric routing, traditional monitoring systems misrepresent the BGP table with inaccurate source ASNs.
Legacy traffic analysis systems that don’t peer EBGP with customers will report inaccurate source ASN. It is not very good when troubleshooting a DDoS attack, and the source ASN information is incorrect.
Most legacy systems don’t offer accurate, complete AS-Path information, leading to false positives and the inability to determine friend from foe. It’s far better for the solution to peer BGP with the customer, extract NetFlow / IPFIX BGP / sFlow locally, and then correlate the data to provide a unified source of truth.
A key point: IPFIX BGP
BGP data can be correlated with IPFIX data so that the paths available in the network are shown, what paths are being used, and the traffic volume on each path between autonomous systems. BGP IPFIX Analysis correlates IPFIX records with BGP routing info to visualize AS paths and how much traffic is traversing these paths in real-time. IPFIX BGP: Analysis correlates IPFIX records with BGP routing info to visualize AS paths and how much traffic is traversing these paths in real-time.
Origin ASN and Peer ASN provide the data flow endpoints, and NetFlow is used in the middle. We can utilize GeoIP Information to analyze the county, region, and city. Correlate this with the complete AS-Path list, and you now have a full view of the source and destination paths with all the details of the middle points.
IPFIX Big Data allows organizations to gain deeper insights into their network traffic. By leveraging the power of advanced analytics, organizations can enhance network monitoring, traffic analysis, and incident response. However, addressing the challenges associated with implementing IPFIX Big Data is crucial to harness its potential fully.
