On day 96 of my 100 days of cybersecurity challenge, I explored the HackRF One tool, a versatile software-defined radio (SDR) device. This hands-on experience deepened my understanding of radio frequency (RF) technology and its applications in cybersecurity, including wireless network analysis, signal monitoring, and radio frequency testing. #Cybersecurity #InfoSec #Security #Tech #Hacking #CyberAwareness #DigitalSecurity #InfoSecurity #Privacy #DataProtection #CyberThreats #EthicalHacking #NetworkSecurity #ITSecurity #WebSecurity #CyberCrime #PenTesting #VulnerabilityAssessment #CyberDefense #OnlineSafety #Hackers #CyberAware #InfoSecCommunity #SecurityTraining #CyberSkills #CyberLearning #CyberEducation #HackRF HackRF One HackRF One from Great Scott Gadgets is a Software Defined Radio peripheral capable of transmission or reception of radio signals from 1 MHz to 6 GHz.

🚀Hello linkedin fam!🚀 🔐 Day 89 of 100 Days Cybersecurity Challenge 🔐#100dayschallenge #sdr #cybersecurity 💪Today;s focus: Software Defined Radio (SDR)! 📡 SDR revolutionizes the way we interact with radio frequency (RF) signals. Unlike traditional radios, which are hardware-based and have fixed functionality, SDR relies on software to process, manipulate, and decode RF signals. This flexibility empowers cybersecurity professionals to adapt to evolving threats and technologies more efficiently. A software-defined radio (SDR) is a wireless device that typically consists of a configurable RF front end with an FPGA or programmable system-on-chip (SoC) to perform digital functions. Commercially available SDR hardware can transmit and receive signals at different frequencies to implement wireless standards from FM radio to 5G, LTE, and WLAN. A basic SDR system may consist of a computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. A software-defined radio (SDR) system is a radio communication system that uses software to process various signals (modulation, demodulation, decoding, etc.) in lieu of the traditional hardware components that are generally made for those dedicated tasks. 💡💪 #CybersecurityChallenge #SoftwareDefinedRadio #SDR #InfoSec

I'm happy to share my most recent publication (Taylor, Pope, "Hardware Sequence Combinators", ICCWS 2024) - A custom hardware traffic validator used in cybersecurity applications to parse high-speed network traffic between two connected devices and "dropping" data payloads that do not adhere to a formal specification (i.e., malicious/ill-formed payloads). This was an interesting project that required optimizing a discrete system, operating with limited resources, in a high-bandwidth network application. The device works by fully automating a process that transforms a user-defined formal grammar (written in Bison/Hammer), which specifies the acceptance criteria of every byte within a data payload, into a hardware circuit on an FPGA that is connected in series between two devices on an ethernet cable. The result ".... acts as a hidden “bump-in-the-wire” that either forwards or drops individual packets based on the message parsing outcome, thereby hardening network segments against zero-day attacks and persistent implants." The novelty of the Sequence Combinator is that we developed an algorithm to compress the table size of a push-down automata (up to 95% on a JSON parser) by combining sequences of characters within the grammar into a reduce the number of symbols/states that can be implemented as a push-down automata in hardware. This "compression" of the Sequence Combinator leads to 90% reduction in BRAM resources on an FPGA - enabling the device to operate at a data rate of 17.5Mbps - making it suitable for parsing traffic CAN bus traffic on-the-fly. (Please see image of the device below.) This project was a wonderful collaboration with Steve Taylor and Jason Dahlstrom from Thayer School of Engineering at Dartmouth / Web Sensing LLC and I really enjoyed working with their team. https://lnkd.in/erfbZp8c #cybersecurity #parsing #bison #compression #embeddeddevices (Below is an image of the FPGA (Web Sensing LLC) that implemented the Sequence Combinator. Two ethernet cables (Input/Output) can be attached to the ethernet connector on the left side and the device.)
