Understanding WiFi Security Vulnerabilities and SolutionsAirTight Networks
Â
These slides include discussion on important Wi-Fi security issues and the solutions available to address them. Enterprises which need to secure their networks from Wi-Fi threats in order to protect their information assets, prevent unauthorized use of their network, enforce no-Wi-Fi zones, and meet regulatory compliance for themselves and their clients will benefit from this discussion.
Cracking of wireless networks is the defeating of security devices in Wireless local-area networks. Wireless local-area networks(WLANs) â also called Wi-Fi networks are inherently vulnerable to security lapses that wired networks Cracking is a kind of information network attack that is akin to a direct intrusion. There are two basic types of vulnerabilities associated with WLANs: those caused by poor configuration and those caused by weak encryption.
"Security & Privacy in WLAN - A Primer and Case Study"
The objective of this paper is to illustrate a primer on Wireless Local Area Network (WLAN) security issues along with an experiment on WLAN penetration test in a live network.
This workshop aims to give an intermediate-level understanding of the potential risk associated with cellular mobile communication networks and the security issues in the radio access network. In particular, we begin with a brief history of Telecom, fundamentals of mobile network, radio signals, the security architecture of GSM/UMTS/LTE, cellular network attack detection methods, and security vulnerabilities with possible practical examples with case studies.
An IDS for Secure Visible Light Communication on Android DevicesBen Graham
Â
This poster concisely presents my research during my time at Florida International University. Experiments showed that data could be transferred to Android devices via sensor inputs, allowing the light sensor to be abused by environment light modulation and malware to be triggered or possibly transferred and data such as location information to be detected. With the development of an Android ROM to monitor this abuse, the sensory channel can be secured.

Beacon frames â A series of frames used in WiFi (802.11) to establish the presence of a wireless network device.
Bluebugging â The use of a Bluetooth-enabled device to eavesdrop on another personâs conversation using that personâs Bluetooth phone as a transmitter. The bluebug application silently causes a Bluetooth device to make a phone call to another device, causing the phone to act as a transmitter and allowing the listener to eavesdrop on the victimâs conversation in real time.
Bluejacking â The sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, tablets, or laptop computers.
Bluesnarfing â The unauthorized access of information from a Bluetooth-enabled device through a Bluetooth connection, often between phones, desktops, laptops, and tablets.
Bluetooth DOS â The use of Bluetooth technology to perform a denial-of-service attack against another device. In this attack, an attacker repeatedly requests pairing with the victim device. This type of attack does not divulge information or permit access, but is a nuisance. And, more importantly, if done repeatedly it can drain a deviceâs battery, or prevent other operations from occurring on the victimâs device.
Captive portal â A website used to validate credentials before allowing access to a network connection.
Containerization â Dividing a device into a series of containers, with one container holding work-related materials and the other personal materials.
Custom firmware - Firmware for a device that has been altered from the original factory settings.
Direct-sequence spread spectrum (DSSS) â A method of distributing a communication over multiple frequencies to avoid interference and detection.
Disassociation â An attack against a wireless system designed to disassociate a host from the wireless access point, and from the wireless network. Disassociation attacks stem from the deauthentication frame that is in the IEEE 802.11 (Wi-Fi) standard.
Extensible Authentication Protocol.
A Survey on Communication for SmartphoneEditor IJMTER
Â
Nowadays security and privacy issues are getting more and more important for people using state of the art communication tools like mobile smartphones or internet.As the power and feature of smartphones increases,so has their vulnerability.By using short range wireless
communication smartphones communicates each other.But the data confidentiality is not guaranteed.In bar code and Near Field Communication enabled devices the smartphones exchange information by simple touch.The main drawback of Near Field Communication and bar code systems is the vulnerable nature to attack since they are using key exchange then encrypt techniques.In the smartphones with android platform,it is possible to provide security against all the
attacks by securely exchanging message or data with-out using key exchange protocol. PriWhisper is an technique that enables key less secure acoustic communication for smartphones and provides better security as well as data confidentiality.
Security in Wireless Sensor Networks Using BroadcastingIJMER
Â
Wireless sensor networks as one of the growing technology in the coming decades has posed various unique challenges to researchers. A WSN typically consists of several base stations and thousands of sensor nodes, which are resource limited devices with low processing, energy, and storage capabilities.While the set of challenges in sensor networks are diverse, we focus on security of Wireless Sensor Network in this paper. As todayâs world is growing more towards the Wireless technology, our aim must be towards providing the best security features to Wireless Sensor Network( WSN).We propose some of the security requirements for Wireless Sensor Network. Further, security being vital to the acceptance and use of sensor networks for many applications. We propose an efficient broadcast authentication scheme for wireless sensor networks in this paper.

Embracing GenAI - A Strategic ImperativePeter Windle
Â
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
Â
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasnât one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
