Security protocols in constrained environments
Security protocols like SSL, TLS, and SSH can be implemented on low-power embedded systems but with some challenges. On low-end 8-bit AVR microcontrollers like those in most Arduinos, security protocols are not feasible due to insufficient SRAM. Mid-to-high-end ARM-based microcontrollers can support security protocols with effort to configure libraries, keys, and cipher suites. Linux-based systems like the Raspberry Pi easily support security protocols using package managers. The main issues are limited memory on low-end systems and needing to handle libraries, keys, and cipher suites for higher-end embedded platforms.
Hack wifi password using kali linux
This document provides instructions for hacking WiFi passwords using Kali Linux. It describes downloading and configuring Kali Linux in a virtual machine. An external USB antenna is used to monitor WiFi networks. The airodump-ng tool is used to detect networks and capture data, which is then cracked using a dictionary attack with aircrack-ng. If the network is not busy, deauthentication packets can be sent to force password transmission. Following these steps, the document claims the password for a sample network was successfully cracked.
Logs, Logs, Every Where, Nor Any Byte to Grok
The document discusses the importance of logs in network forensics investigations. It introduces Logstash, an open-source tool for centralized log aggregation and analysis. Logstash allows ingestion of logs from many sources in various formats, filtering and parsing of logs, and output to search databases. The document demonstrates using Logstash to ingest sample log files to provide a holistic view of network activity for investigation.

Decoupling Distributed Systems from IP Networks
Take a trip with Derek Collison into the history of distributed systems, the good and the bad, and now how to move forward.
I psec
IPSec provides security for IP communications by authenticating packet sources and ensuring data integrity and confidentiality. It uses the IKE protocol to securely establish encryption keys between two endpoints to enable the use of AH and ESP protocols. IPSec policies define rules for establishing Phase 1 IKE security associations for authentication and Phase 2 associations for applying encryption and other security measures to specific traffic.

The document provides an overview of 10 new topics related to network security on the CompTIA Security+ SY0-301 exam. The new topics covered include web security gateways, load balancers, flood guards and loop protection, cloud computing, secure file transfer protocols, differences between IPv4 and IPv6, wireless networking standards like WEP, WPA, and WPA2, wireless authentication technologies such as EAP, PEAP and LEAP, wireless security features including MAC filtering, TKIP and CCMP, and considerations for wireless installation including antenna placement and power level controls.
Implementing a Secure and Effective PKI on Windows Server 2012 R2
The infrastructure that deploys and manages digital certificates, known as a Public Key Infrastructure (PKI), is often the center for cryptography in an organization. It is also in service for 10+ years, which means that one must carefully consider design options before implementation. In this presentation, Frank will cover modern standards for cryptography, how they apply to a Microsoft PKI infrastructure, and share recommendations based on he has seen in the field.
How Smart Thermostats Have Made Us Vulnerable
The document discusses security vulnerabilities in smart home thermostats like the Nest Thermostat. It describes how the thermostats can be hacked by exploiting weaknesses in their hardware, software, and firmware. Specifically, it shows how accessing a device's USB port allows injecting custom code to gain full control over the thermostat and access user data and accounts. The talk urges manufacturers to implement stronger authentication of code and encryption to protect smart home devices and data.
Cours4.pptx
TLS is a cryptographic protocol that provides communication security over the internet. It allows for confidentiality and authentication of communications through key exchange and encryption of the record layer. However, TLS has faced numerous attacks over the years that exploit weaknesses in its implementations, cipher suites, and compatibility with older versions. Ideal patches often require removing vulnerable features completely, but real-world patches typically aim to preserve compatibility and usability while improving security. As a result, attacks on TLS continue to emerge as new vulnerabilities are discovered.

Defense in depth: practical steps to securing your data and achieving compliance
Presented by Chris Purrington, the VP Sales Europe at Cohesive Networks
Perimeter-based security approaches have not evolved to meet the modern application-focused enterprise. The weaknesses of the perimeter-based approach are on display in the east/west attacks on Sony, Target, and Home Depot exploits where hackers gained access to the perimeter, then ransacked the internal networks with minimal resistance. What can modern enterprises do? A “defense in depth” approach to security at the network layer. Enterprises must strengthen existing core networking hardware and virtualization layer security with added application security. In data centres, physical network isolation is not practical, and logical segmentation can be very difficult without using evolved networking approaches. As data centers became wholly virtualized and blur the line between data center and private cloud, we can finally add and control logical segmentation at the virtualization layer. This “Application Segmentation” provides the most comprehensive security model available today. You can apply application segmentation defense in depth using Cohesive Networks’ VNS3:turret. VNS3:turret creates a cryptographically unique micro-perimeter around each application topology. This presentation will examine how an defense in depth at the application layer can stop the next Sony attack.

The document discusses rethinking cloud application security in 2016. It argues that data center security models do not work for cloud security and that applications need security through network virtualization. Upcoming compliance regulations will emphasize network segmentation, application security, and isolation. The document recommends using application layer switches and network controls like micro-perimeters, encrypted overlays and traffic policies to build secure layers of access and control for cloud applications. This will help make 2016 a more secure year.

- 4. copyright 2014 Agenda • Anatomy of a security protocol • The key exchange dance • Linux makes things easy • Libraries for higher end microcontrollers • SRAM on low end microcontrollers • 2014 – things happened • Summary
- 5. copyright 2014 Which security protocols? The ‘S’ protocols: Secure Sockets Layer (SSL) Superseded by Transport Layer Security (TLS) Secure SHell (SSH) Internet Protocol Security (IPsec)
- 8. copyright 2014 It’s a similar story for SSH
- 10. copyright 2014 Linux makes this easy If not already built in to a particular distribution then use favourite package manager to get: (no relation)
- 11. copyright 2014 Things get trickier with embedded But by no means impossible…
- 12. copyright 2014 Stack trades offs may be made
- 13. copyright 2014 But those keys won’t fit into 2K At least not with anything resembling a useful application… … regular Arduino struggles with MQTT and 1wire
