Overlay networks
Overlay networks are virtual networks built on top of existing networks that add additional layers of indirection. There are several types of overlay networks including caching, routing, and security overlays. Two examples of anonymous communication networks are ACN and I2P. I2P uses "garlic routing" which involves layered encryption, bundling multiple messages together, and ElGamal/AES encryption. It has a distributed, self-organizing design and uses short-lived, unidirectional tunnels to provide anonymity through its network.
Using Canary Honeypots for Network Security Monitoring
In this presentation I talk about how honeypots that have more traditionally been used for research purposes can also be used as an effective part of a network security monitoring strategy.

Software Defined Networks
By: Thierry Couture, Consulting Systems Architect
There is currently a lot of buzz around OpenFlow and Software Defined Networks (SDN) in the industry. It would be a mistake to think that these are one and the same. The reality is that the current market conversation has loose semantics mixed in with hyperbole and hearsay that hide the simplicity of SDN behind terms like Openstack, Virtual Overlays, Network Function Virtualization, Orchestration, etc. This session will explain the origins of SDN, establish a basic terminology for SDN concepts, and offer a framework to both understand these trends and distill the applicability of SDN through a use case lens.

[cb22] Tales of 5G hacking by Karsten Nohl
An expert in mobile network security provided a summary of hacking 5G networks. Some key points include:
1) Standard IT security techniques uncovered issues when applied to upgraded legacy 4G networks, such as unpatched operating systems, weak configurations, and lack of encryption.
2) Future 5G networks introduce new security risks due to increased complexity from virtualization and automation layers, as well as a continuously evolving attack surface extending into cloud infrastructure.
3) Red team exercises show that hacking mobile networks has become a multi-step process, where initial access through one vulnerability can enable lateral movement and privilege escalation to compromise critical systems or customer data.

Tutorial WiFi driver code - Opening Nuts and Bolts of Linux WiFi Subsystem
While we understand the complex interplay of OSI layers, in theory, in practice understanding their implementation is a non-trivial task. The implementation details that enables a network interface card to communicate with its peers are oblivious to the end-users. Developers venturing into this domain for the first time often find it hard to find relevant tutorials that enable them to understand these implementation details. The aim of this talk is to provide an overview of WiFi Subsystem implemented in the Linux operating system. Specifically, this talk will explain the sequence of events that occur from application layer till physical layer when a connection is established over WiFi. After this talk, the audience will understand
(1) the bird's eye view of Linux WiFi Subsystem,
(2) what happens in an operating system when a WiFi card is plugged-in,
(3) how is a packet received/transmitted from physical layer to operating system kernel and vice-versa,
(4) brief overview of code structure of open-source drivers, and lastly
(5) important pointers to kick start driver code modifications.

Security in WSN
1) Wireless sensor networks consist of hundreds or thousands of low-cost, low-power sensor nodes deployed to monitor environments. They require security to protect data confidentiality, integrity, and availability given their resource constraints and vulnerability to physical attacks.
2) Standard approaches to achieve security include encrypting data for confidentiality, using protocols like uTESLA for integrity and time synchronization for freshness. However, sensor nodes face obstacles like limited memory, energy constraints, and unreliable communication.
3) Wireless sensor networks are susceptible to various network layer attacks like spoofing, selective forwarding, sinkhole attacks, Sybil attacks, and wormholes. Countermeasures include link layer security, geographic routing, multi-path routing, and authentication.

Removing Uninteresting Bytes in Software Fuzzing
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.
