SDN programming and operations requires continuous monitoring of network and application state as well as consistent configuration and update of (forwarding) policies across heterogeneous devices. This is resulting in significant challenges.
Multiple open protocols such as OpenFlow, OF-CONFIG, OnePK , etc. are being adopted by different vendors causing an integration problem for developers.
Internet of Things applications are pushing the size and volume of data handled by SDN systems demanding more efficient and scalable protocols for information distribution and coordination of SDN devices.
This presentation will describe these and other SDN challenges and ways in which various open protocols, such as DDS, XMPP, AMQP, are being used to address them.
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

§ Ethernet Virtual Private Network (EVPN) and Provider Backbone Bridging EVPN
(PBB-EVPN) designed to address these requirements
Next-Generation Solutions for L2VPN
§ Per-Flow Redundancy and Load Balancing
§ Simplified Provisioning and Operation
§ Optimal Forwarding
§ Fast Convergence
§ MAC Address Scalability
36. Solving VPLS Challenges for per-flow Redundancy
Next-Generation Solutions for L2VPN
• Existing VPLS solutions do not
offer an All-Active per-flow
redundancy
• Looping of Traffic Flooded from
PE
• Duplicate Frames from Floods
from the Core
• MAC Flip-Flopping over
Pseudowire
– E.g. Port-Channel Load-Balancing
does not produce a consistent
hash-value for a frame with the
same source MAC (e.g. non MAC
based
Hash-Schemes)

37. All Active Redundancy and Load Balancing
• All-Active Redundancy to maximize bisectional bandwidth
• Load-balance traffic among PEs and exploit core ECMP based on flow
entropy (flow can be L2/L3/L4 or combinations)
• Support geo-redundant PE nodes with optimal forwarding
• Flexible Redundancy Grouping of PEs

41. Mac Address Scalability
• Server Virtualization fueling growth in MAC Address scalability:
– 1 VM = 1 MAC address.
– 1 server = 10’s or 100’s of VMs
• MAC address scalability most pronounced on Data Center WAN Edge for Layer 2
extensions over WAN.
– Example from a live network: 1M MAC addresses in a single SP data center

42. Ethernet VPN
• Next generation solution for Ethernet
multipoint (E-LAN) services
• PEs run Multi-Protocol BGP to
advertise & learn Customer MAC
addresses (C-MACs) over Core
– Same operational principles of L3VPN
• Learning on PE Access Circuits via
data-plane transparent learning
• No pseudowire full-mesh required
– Unicast: use MP2P tunnels
– Multicast: use ingress replication over
MP2P tunnels or use LSM
• Under standardization at IETF – draft-

43. PBB Ethernet VPN
• Next generation solution for Ethernet multipoint
(E-LAN) services by combining Provider
Backbone Bridging (PBB - IEEE 802.1ah) and
Ethernet VPN
• Data-plane learning of local C-MACs and
remote C-MAC to B-MAC binding
• PEs run Multi-Protocol BGP to advertise local
Backbone MAC addresses (B-MACs) & learn
remote B-MACs
– Takes advantage of PBB encapsulation to
simplify BGP control plane operation – faster
convergence
– Lowers BGP resource usage (CPU, memory)
on deployed infrastructure (PEs and RRs)

§ Relies on BGP control-plane for Segment / MAC learning reachability
among PEs
§ Same principles as L3VPNs
§ Benefits of xEVPN solutions
§ No signaling of PWs. Instead signals MP2P LSPs instead (ala L3VPN)
§ All-active CE multi-homing (per-flow LB)
§ Solution for P2P services uses a subset of EVPN routes
§ i.e. Per-EVI Ethernet Auto-Discovery route
