The term Internet of Things (IOT), also alluded to as web of
Items alludes to the organized interconnection of regular objects, that is
normally seen as a self-arranging remote system of sensors whose reason would
be to interconnect all things 12. Supervisory control, data acquisition
system control and monitors the industrial systems such as nuclear plant,
automotive vehicle systems, telecommunication systems, large organization data
centers etc…

Supervisory control and data acquisition systems monitor the
systems processes and take appropriate actions to control the systems. It is
the central point of supervision in which each process monitor. Modern Scada
systems used both the CPS and IOT cloud based environment. As this is the
latest technology and widely spread around the world these days. So, it faces
many security challenges.

In this paper, we review some paper and past work in
those papers taken for the reliable and more secure wireless network for both
source and sender. We also see different issues and their countermeasure for to
tackle those issues.




7 The IoT heterogeneous core, components, knowledge,
flexibility Associate in Nursingd unclear outskirts makes it an interest
advancement region however what is more makes the IoT weak and hazardous
underneath security terms. The differing stages wherever the IoT is open makes
it considerably additional hard for security examiners to seek out sweeping
responses for this security challenges. during this manner, the spatial
relation of cognizance the foundation and therefore the elements of the IoT
advances toward attending to be important.










RFID structure


9 In the RFID structure, the RFID tag is possible to spill
fragile information of the proprietor to the unapproved peruser, so the
encryption is to be relied upon to ensure protection.




In the middleware system, the
essential security objective is to guarantee the correspondence security
between the RFID peruser likewise, the info server. meantime the info server
should be secured to show away DOS strike. This is a ordinary security issue.


 Internet system.


In the net structure, the regular framework security issues
area unit have to be compelled to are apprehended, as an example, how to shield
the info from being crushed and the way to guarantee the safety and integrality
of information in web.





 1   In our first paper the authors discuss about
the different security issues arises in sensor network and their solutions.

Sensor network consist of three units.

Sensor unit, micro controller and radio unit.

Sensor units use secure communication like scrambled data and
connection between unit and base station is also secure with some scrambled
technology. These are used in military defense, industry, construction etc…

Wsn have limited resources like capacity, processing power
energy usage etc. unreliable communication is also a matter of security lapses,

 security is
very hard such networks. Data confidentiality, authentication communication,
accuracy, reliability are the main issues which are to tackle on priority



The author also discusses about the different techniques to
resolve the security issues like secure routing protocols, secure data
aggregation intrusion detection techniques, data encryption etc…


2    in this paper
authors discussed about the 5G network communication and challenges such as how
to implement network also it security and technical issues.

Authors emphasizes on direct communication among
devices irrespective of base station dependent or base station management. Base
station just to manage this direct communication and act as passive network


Also, direct to direct and multi users connect each other
without any main base station supervision.

There many technical challenges arise in this structure like
standards, structure of the network. Base station role in this local network
and security measures like authentication, data communication etc… pricing and
network quality also play very important role.



3    this paper
emphasis on the 5G implementations and core factor of its deployment in 5G
cloud services. There are two main factors of 5G network deployment













Dense deployments and centralized
processing. Flexibility and scalability is main fundamental factors for future
network infrastructures. Flexibility is achieved with cloud computing concept.
Cloud computing functionality achieved with network virtualization NSV and SDN

Radio access networks uses these technologies.
Flexible RAN concept is introduced for to tacke the challenges in 5G RAN. As
more devices ad, more data is in future demands as 5G will serve for latency,
throughput data volume, mobility etc…it operates on Ultra dense deployment of
infrastructure concepts used in which we deploy the network such as RAP and
user node distance and data traffic load is managed that number of sites deployment
managed the load and data traffic also number of sited consumes more power.

Centralized processing is also core feature for this
type of communication RRM radio resource management algorithm allows the
multiple user load at single level to manage. C-RAN centralized resource
allocation network technique is also use for this purpose in which multiple
sites are connected through centralized mechanism of controlling.

4 in this paper the author discusses about the
security challenges in 5G network. Multitier approach is used to secure
software defined model network architecture by managing security issues in
different layers. Network channel is secure with the help of HIP and IPsec
tunneling technology method. Different methods are used to tackle different
security issues such as spoofing, denial of services, backhauling, flooding
attacks etc…

There are multi type of security threats in SDMN



IoT courses of action should use security frameworks
that let, in light-weight of the end-customer call, access to a
“predefined set of advantages”, equally referred to as information

it’s needed then a partition for the safety
necessities of things in light-weight of criticality, shows the hugeness on the
qualification for every of the IoT layers, the association layer, the framework
layer and therefore the application layer. Current IoT progresses manage
information security shapes, together with key organization, that puts a weight
on IoT resources which will diminish IoT limits and addition probability.
Proposes the use of light-weight scientific discipline counts so the advantage
confined IoT devices, particularly to method and limit capacities, will provide
information security and, thusly, order. Datagram Transport Layer Security (DTLS)
may be used as a response for mystery problems by offering end-to-end security
to the appliance layer. DTLS properties could equally scale back the impact and
therefore the value of benefits of duty-bound devices stood out from varied
courses of action Remembering the last word objective to ensure information and
correspondence security





considering the IoT starting at in recent times it are
often anywhere on that countermeasures, to thwart the IoT from assaults,
bringing approximately protection issues affecting its customers, are winding
up more possible. Validation and cryptography will guard the IoT’s key
additives RFID and NFC from excessive attacks, nevertheless, they’re no longer
relevant to WSNs. within the previous couple of years, the web of factors has
been drawing in a incredible association of consideration, and due to the fact
the center innovation inside the detecting element layer of IOT, RFID in
addition can pull within the various enthusiasm for the years to return. amid
this newsletter, we will be inclined to sum matters up audited the insurance
problems within the IOT strengthened RFID, and dissected protection efforts and
risks, at that point we have a tendency to distinctive this countermeasures
amid this area. at the contrary whole of the range, the person of each bodily
tactics and IoT devices mortgage themselves to the development of most current
security systems. As particular, regular co-relations among physical wonders
are frequently abused to locate safety and wellness disappointments.
essentially, the inevitable cease made from bodily processes is any other
avenue with a view to be wont to find anomalous occasions. At last, providing
thoughts from the management building international into IoT level development
(for instance, precise enter circles) may prompt a more comfortable and more at
ease IoT.
