A SURVEY OF THE S TATE OF THE A RT IN Z IG B EEIJCI JOURNAL
ZigBee is one of the most widely used wireless comm
unication technologies. ZigBee is being widely used
for sensor communications and many other research f
ields. Why consider ZigBee? Because it is cheap and
has better compatibility when compared to other com
munication technologies. We have given a detailed
description on comparison between all the available
technologies. In this paper, we have discussed so
me
basic concepts about ZigBee and its security aspect
s in networking. We have also listed out the major
manufacturers who are into the production of the tr
ansceivers for ZigBee
Gas leakage is an important problem. It wastes energy and sometimes it causes harmful effects to lives. We have limited energy resources. Proper utilization of resources is need of the time. We have proposed a gas safety management system
using ZigBee to monitor flow and pressure of gas, earthquake, temperature, smoke and leak of methane. It also provides a health safety system simultaneously by automating the associated devices with its embedded programmed feature to procure the environment by completely eradicating the harmful source. Through this dynamic technology, we can establish a well economic and health caring system in this
rapidly developing era to excel our country.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

4. Technological Standard Created for Control and Sensor
Networks
Based on the IEEE 802.15.4 Standard
High level Communication
Operates in Wireless Personal Area Networks (WPANs) and
Device-to-Device networks
Created by the ZigBee Alliance
Connectivity between small packet devices
Control of lights, switches, thermostats, appliances, etc.
5. ZigBee-style networks began to be conceived about 1998,
when many engineers realized that both WiFi and Bluetooth
were going to be unsuitable for many applications.
In particular, many engineers saw a need for self-organizing
ad-hoc digital radio networks.
The IEEE 802.15.4 standard was completed in May 2003.
The ZigBee specifications were ratified on 14 December
2004.
The ZigBee Alliance announces public availability of
Specification 1.0 on 13 June 2005.
6. There are three different types of ZigBee device:
ZigBee coordinator (ZC)
ZigBee Router (ZR)
ZigBee End Device (ZED)
7. ZigBee coordinator (ZC): The most capable device, the
coordinator forms the root of the network tree and might
bridge to other networks.
There is exactly one ZigBee coordinator in each network. It
is able to store information about the network, including
acting as the repository for security keys.
8. ZigBee Router (ZR): Routers can act as an intermediate
router, passing data from other devices.
ZigBee End Device (ZED): Contains just enough
functionality to talk to its parent node (either the coordinator
or a router); it cannot relay data from other devices. It
requires the least amount of memory, and therefore can be
less expensive to manufacture than a ZR or ZC.
9. Low cost
Low power consumption
Low data rate
Relatively short transmission range
Scalability and reliability

Mostly Static networks with many, infrequently used devices
Home automation, toys, remote controls, etc.
Bluetooth
Larger packets over small network
Ad‐hoc networks
File transfer
Screen graphics, pictures, handsfree audio, Mobile phones,
headsets, PDAs, etc.
19. In all of its uses, zigbee offers four inherent, beneficial
characteristics:
Low cost:
Range and obstruction issue avoidance:
Multisource products:
Low power consumption:
21. A recent analyst report issued by West Technology
Research Solutions estimates that by the year 2008,
"annual shipments for ZigBee chipsets into the home
automation segment alone will exceed 339 million
units," and will show up in "light switches, fire and
smoke detectors, thermostats, appliances in the kitchen,
video and audio remote controls, landscaping, and
security systems."
Futurists are sure to hold ZigBee up and say, "See, I told
you so".
22. ZigBee is one of the global standards of communication
protocol formulated by the relevant task force.
ZigBee is the newest and provides specifications for devices
that have low data rates, consume very low power and are
thus characterized by long battery life.
