Veena Venugopal presented on cloud security and proposed an efficient and secure protocol for data storage in cloud computing. The protocol has three phases - setup, verification, and dynamic operations and verification. In the setup phase, the user encrypts and generates metadata for the file. A third party auditor verifies the integrity of the stored data by generating challenges and checking proofs from the cloud server. The protocol also supports dynamic operations like modification, insertion, and deletion of blocks while maintaining security. It provides confidentiality, public verifiability, and supports efficient dynamic operations on outsourced data in the cloud.
Cloud Computing offers an on-demand and scalable access to a shared pool of resources hosted in a data center at providers’ site. It reduces the overheads of up-front investments and financial risks for the end-user. Regardless of the fact that cloud computing offers great advantages to the end users, there are several challenging issues that are mandatory to be addressed.
This presentation is on the basics of cyber security and cloud computing, where it also addresses the aspects ethical hacking in detail.

Historical development of cloud computinggaurav jain
The historical development of cloud computing began in the 1950s with AT&T developing a centralized data architecture and network to enable businesses to access information over updated phone lines. Over subsequent decades, technologies like internet service providers, application service providers, and utility computing emerged, establishing the principles of centralized, on-demand computing resources delivered over a network. These precursors to modern cloud computing included distributed systems, mainframes, grid/supercomputing, and Web 2.0 technologies that emphasized sharing information and collaboration online in a more dynamic way.

It then discusses key considerations for cloud security including identity and access management, security threats and countermeasures, application security, operations and maintenance, and compliance. Chief information officer concerns around security, availability, performance and cost are also addressed.
Cloud computing is a model which uses the mixture concept of “software-as-a-service” and “utility computing”, and provides
various on-demand services in a convenient way requested end users. It is internet based where resources are shared and the
information is available for on demand service users. Security issue in Cloud computing is the important and critical issues
because the resources are distributed. Both the Cloud provider and the cloud consumer should be fully sure that the cloud is safe
enough from all the external threats so that the customer does not face any kind of problem like loss or theft of their valua ble
data. There is also a possibility where a malicious user can penetrate the cloud by imitate an authorized user, and affect with a
virus to the entire cloud and affects many customers who are sharing the infected cloud. In this paper we firstly lists the
parameters that affects the security of the cloud then it explores the security issues of cloud computing and the troubles faced by
providers and consumers about their data, privacy, and infected application and security issues. It also presents some security
solutions for tackling these issues and problems.
Trust based Mechanism for Secure Cloud Computing Environment: A Surveyinventionjournals
Ubiquitous computing has revolutionized interaction of humans and machines. Cloud computing has been mainly used for storing data and various computational purposes. It has changed the face of using the internet. But, as we know every technology has its pros and cons. Securing cloud environment is the most challenging issue for the researchers and developers. Main aspects which cloud security should cover are authentication, authorization, data protection etc. Establishing trust between cloud service providers (CSP) is the biggest challenge, when someone is discussing about cloud security. Trust is a critical factor which mainly depends on perception of reputation and self-assessment done by both user and CSP. The trust model can act as security strength evaluator and ranking service for cloud application and services. For establishing trust relationship between two parties, mutual trust mechanism is reliable, as it does verification from both sides. There are various trust models which mainly focuses on securing one party i.e., they validate either user or service node. In this survey paper, the study of various trust models and their various parameters are discussed.

Cloud Computing Using Encryption and Intrusion Detectionijsrd.com
Cloud computing provides many benefits to the users such as accessibility and availability. As the data is available over the cloud, it can be accessed by different users. There may be sensitive data of organization. This is the one issue to provide access to authenticated users only. But the data can be accessed by the owner of the cloud. So to avoid getting data being accessed by the cloud owner, we will use the intrusion detection system to provide security to the data. The other issue is to save the data backup in other cloud in encrypted form so that load balancing can be done. This will help the user with data availability in case of failure of one cloud.

Cloud computing is an internet-based computing technology, where shared re-sources
such as software, platform, storage and information are provided to customers on demand.
Cloud computing is a computing platform for sharing resources that include infrastructures,
software, applications, and business processes. The exact definition of cloud computing is A
large-scale distributed computing paradigm that is driven by economies of scale, in which a
pool of abstracted, virtualized, dynamically scalable, managed computing power, storage,
platforms, and services are delivered on demand to external customers over the Internet .
Abstract: Cloud computing model are obtaining ubiquitous authorization due to the heterogeneous convenience they provide. Although, the
security & privacy problems are the main considerable encumbrance holding back the universal adoption of this new emerging technology.
Various researches are concentrated on enhancing the security on Software as well as Hardware levels on the cloud. But these interpretations do
not mainly furnish the complete security way and therefore the data security compute (measure) are still kept under the access control of service
provider. Trusted Computing is another research concept. In actuality, these furnish a set of tools controlled by the third party technologies to
secure the Virtual Machines from the cloud computing providers. These approaches provides the tools to its consumers to assess and monitor the
aspects of security their data, they don’t allocate the cloud consumers with high control capability. While as the new emerging DCS approach
aims to provide the security of data owners of their data. But the DCS approach concept is elucidate in many ways and there is not a
standardized framework of cloud computing environment model for applying this approach.

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

This is a great way to be more productive but a few things to
Keep in mind:
- The 8+8+8 rule offers a general guideline. You may need to adjust the schedule depending on your individual needs and commitments.
- Some days may require more work or less sleep, demanding flexibility in your approach.
- The key is to be mindful of your time allocation and strive for a healthy balance across the three categories.

It outlines the basic identity elements such as symbol, logotype, colors, and typefaces. It provides examples of applying the identity to materials like letterhead, business cards, reports, folders, and websites.
Artificial Intelligence (AI) has revolutionized the creation of images and videos, enabling the generation of highly realistic and imaginative visual content. Utilizing advanced techniques like Generative Adversarial Networks (GANs) and neural style transfer, AI can transform simple sketches into detailed artwork or blend various styles into unique visual masterpieces. GANs, in particular, function by pitting two neural networks against each other, resulting in the production of remarkably lifelike images. AI's ability to analyze and learn from vast datasets allows it to create visuals that not only mimic human creativity but also push the boundaries of artistic expression, making it a powerful tool in digital media and entertainment industries.
3. What is CLOUD COMPUTING?
The most demanding computing.
Cloud computing means storing and accessing data and
programs over the Internet instead of your computer's
hard drive. [5]
4. Featuresof cloudcomputing
On demand-self service
Broad Network access
Resource pooling
Rapid elasticity
Measured service
Pricing [10]
5. CHALLENGES
IN CLOUD COMPUTING
o Security
o Costing model
o Charging model
o Service level agreement
o Cloud interoperability issue [7]
6. What do we mean by
CLOUDSECURITY?
Set of control-based technologies and policies designed to
adhere to regulatory compliance rules and protect information,
data applications and infrastructure associated with cloud
computing use.
It can be done without the cost of maintaining facilities and
hardware.
It addresses both physical
and logical security issues across
all service models of software. [3]
7. INTRODUCTION
The Introduction of numerous cloud based services and
geographically dispersed cloud service providers, sensitive
information of different entities are normally stored in remote
servers.
Locations with the possibilities of being exposed to
unwanted parties in situations where the cloud servers
storing those information are compromised. [1]
8. Sometimes, it might be required or at least possible
for a person to store data on remote cloud servers.
Sensitive States of cloudcomputing :
The transmission of personal sensitive data to the cloud
server.
The transmission of data from the cloud server to clients'
computers.
The storage of clients’ personal data in cloud servers which
are remote servers, not owned by the clients. [1]
9. PROBLEM STATEMENT
Cloud security is becoming a key differentiator and
competitive edge between cloud providers. So by applying
the strongest security techniques and practices, cloud
security may soon be more secure than the level that IT
departments achieve using their own hardware and
software.
10. TYPES OF CLOUD
• Private cloud
--The cloud is managed by an organization and serves it
solely.
• Public cloud
--The cloud infrastructure is owned and managed by a large
Cloud Service Provider (CSP).
• Hybrid cloud
--The cloud infrastructure is composed of two or more of
the above models.
• Community cloud
--The cloud is managed by several organizations and
supports a specific community that has the same interest.
[7]
11. If security is not robust and consistent, the
flexibility and advantages that cloud computing
has to offer will have little credibility.
Here, we are going to discuss about the security
issues of cloud computing.
12. SECURITY AND PRIVACY ISSUES
Concerns of security issues:
‼ Availability :
It is to ensure its users can use them at any time, at any
place.
‼ Confidentiality :
It means keeping users’ data secret in the cloud systems.
‼ Data integrity :
It means to preserve information integrity (i.e., not lost or
modified by unauthorized users).
13. ‼ Control :
It means to regulate the use of the system, including the
applications, its infrastructure and the data.
‼ Audit :
It means to watch what happened in the cloud system,
could be added virtualized application environment hosted
on the virtual machine to provide facilities watching what
happened in the system. [3]
14. THREATS TO CLOUD COMPUTING
Data Breaches:
In cloud computing, the virtual machines (VMs) are residing in the
same physical host and when one VM is able to access information
from another VM, data breach occurs.
Data Loss:
The things leading to permanent loss of data include malicious
attacker, hard drive failure, fire or earthquake. Some of these
reasons could be due to the service providers fault.
AccountHijacking:
Account hijacking uses attack methods such as fraud ,exploitation
etc of software vulnerabilities where credentials and passwords
are reused.
15. Denial-of-Service:
This attack attempts to make the system or network resources
unavailable to the users from accessing their data and applications
from cloud.
AbuseofCloudService:
The main concern is for the CSVs rather than cloud service clients
since the users will be trying to hack the system to gain access to
confidential data.
MaliciousInsiders:
The employees who are working for cloud service providers such
as the system administrator will have complete access to the
confidential resources. Their access can be a big threat to
customers to view confidential data. [11]
16. WHY DO WE NEED CLOUD-SECURITY ?
Cloud adoption is expected to accelerate in the coming
years, organizations are still wary of the cloud as the
right delivery environment for many business
applications. The dominant concern is Security.
Businesses question whether their data is safe in
the cloud, and how they can employ an on-demand
service while maintaining regulatory and industry
compliance.
Organizations are right to balk about going head first into
the cloud without some guarantees about protection.
17. SECURITY MEASURES OF CLOUD
User control.
Investigative support, investigating inappropriate or
illegal activity may be impossible in cloud computing.
Intrusion detection and prevention.
18. Misconfiguration takes place, because lack of
expertise coupled with insufficient communication.
Threat to access important information is also a
major concern which can lead to huge loss of data
and can even lead to hacking.
Availability and backup. [23]
20. Denial of Service (DoS) :
Being of the latter is obviously always an issue for
servers. The added risk to using the cloud is that attacks on
other users of the cloud would affect your
portion.
Data Breaches:
Have greater potential of disaster on the cloud. A single
flaw in a cloud service could cause one data breach to extend
to a breach of the entire system.
21. Data loss :
It is an issue not unique to the cloud. Power loss is a
potential scenario everywhere on Earth and sometimes
unavoidable.
Data Integrity :
The risk of giving other access to your server’s internals
and secrets is once again almost unavoidable . Unless you
were to buy, setup, and implement your own server in your
home you will probably have to trust someone else to help
you, thereby risking the data’s integrity. [4]
22. APPLICATIONS OF CLOUD COMPUTING
1) Cloud computing provides dependable and secure data
storage center.
2) Cloud computing can realize data sharing between
different equipments.
3) The cloud provides nearly infinite possibility for users to
use the internet.
4) Cloud computing does not need high quality equipment
for the user and it is easy to use. [3]
23. FUTURESCOPE OF CLOUD SECURITY
It is facing many challenges regarding the security of data.
Modification of this technology helps to secure the data.
Many research on this technology are taking place which
would eventually help this technology to expand its scope in
future leading to more secure data.
Architectures , thus it will help to grow the IT industry as
well as advancement of this technology would help in big
organizations as well as full-fill the requirement of public
industry as well. [23]
24. STEPS TAKEN FOR BETTER CLOUD
There are organizations working towards a more secure cloud,
such as the CSA (CLOUD SECURITY ALLIANCE).
Another is Silver Sky, an expert provider of cloud security and
provider of “the industry’s only advanced Security-as-a-Service
platform from the cloud”.
The CTO of Silver Sky, Andrew Jaquith, explains that many CIOs
are moving their services to the cloud in order to save money,
but that security remains a key concern and these moves may
be insecure or at least hasty.
On the other hand, he also explains that many cloud service
providers are becoming clearer, more transparent, and more
assured than ever before that they could protect customer data.
25. SOLUTIONS OF ISSUESIN CLOUD SECURITY
‼ Network and security audits
‼ Security threat assessments
‼ Secure network and infrastructure design
‼ Network perimeter protection, including firewalls and
intrusion detection
‼ Remote access strategies, including VPN implementations
‼ Data loss prevention for information in motion and at rest
[23]
26. CONCLUSION
The Cloud provides many options for the everyday
computer user as well as large and small businesses.
Clouds are more subjected to the data theft, malicious
access, and unsecured internet access.
Efforts have been made to enforce confidentiality, integrity
and privacy of data.
We have discussed the Issues, Factors Affecting the Data
Security, Threats to it, Measures being taken towards it,
Applications of it as well.
27. The customers before shifting their data enter to cloud,
they should understand the sensitivity of data and choose
the cloud model based on their requirement.
Thus it will help to grow the IT industry as well as
advancement of this technology would help in big
organizations as well as full-fill the requirement of public
industry as well. [23]
