What is Cloud Security?
First of all, what is cloud? – Cloud is a term used for describing a
global network of servers, each with a unique function that are
designed to operate as a single ecosystem.
Cloud security, sometimes referred to as cloud computing
security, is the process of defending infrastructure, applications,
and data stored in the cloud from online threats and attacks. It
offers numerous tiers of defense for the network infrastructure
against things like DDoS assaults, illegal access, and data
breaches.
Through constantly active internet connections, cloud providers
host services on their servers. Customers' trust is essential to
their business, thus they deploy cloud security measures to
protect and safeguard consumer data. However, cloud security
also partially depends on the client.
The following categories make up the basic components of
cloud security:
1. Data protection

4. 4
2. Identification and access management (IAM)
3. Governance (policies on threat prevention, detection, and
mitigation)
4. Planning for data retention (DR) and business continuity
(BC)
5. Legal Compliance
Although cloud security may resemble conventional IT security,
this architecture actually requires a new strategy.

5. 5
Why Cloud Security is important?
In modern-day enterprises, there has been a growing transition
to cloud-based environments and IaaS, PaaS, or SaaS computing
models. In fact, according to Ermetic and IDC reports, 80% of
CISOs believe that their business has had a cloud data breach in
the last 18 months. Out of those, 43% had encountered ten or
more breaches.
Understanding the security standards for protecting data has
grown crucial as businesses move more operations to the cloud.
Although the administration of this infrastructure may be
delegated to third-party cloud computing companies, but this
does not necessarily mean that accountability and security for
data assets are transferred as well.
Most cloud service providers adhere to optimal security
measures by default and actively work to safeguard the
reliability of their servers. Organizations must, however, take
their own factors into account while securing data,
programmes, and workloads that use the cloud.

6. 6
5 reasons why cloud security is important:
 It protects against system vulnerabilities.
A data breach is very risky for a company's financial stability
and may take a long time to be discovered. Data security on
cloud storage platforms becomes even more crucial,
particularly if you choose a public cloud option that grants
access to a third party. Even while it is in your service
provider's best interest to secure your data, a breach is still
possible; in most cases, the customer must go above and
above by using a hybrid system to safeguard the data.
 It facilitates the administration of distant work.
Accessing data from anywhere in the world has been made
much easier thanks to cloud storage. This, however,
underscores how crucial it is that your data be managed
carefully and securely. In certain situations, it's possible
that the staff won't follow the standards that are advised
while using the public internet or personal device. Your
data becomes vulnerable to malware and phishing as a
result of these behaviors, which pose a security risk.
 Disaster recovery is possible by it.
Everyone is aware that any disaster may happen at any
time and have a significant impact on your data and

7. 7
business if you are not adequately safeguarded. It might be
a flood, a fire, or any other natural calamity that could have
a negative impact on your company. Because this might
possibly result in you suffering significant losses, it is crucial
that you're safely secured and your data is protected.
 It also helps comply with regulations
To continue operating lawfully and avoid incurring the
wrath of the regulators, firms must adhere to particular
data protection rules. These safety requirements, such as
HIPPA and GDPR, are practically widespread. They are often
put together to protect business integrity and uphold the
security of businesses using cloud security.
This is so that the cloud security provider won't be held
accountable for any compromised client data. There is no
passing of responsibility; the regulators will hold the
company accountable. Large financial institutions, such as
those in the banking, healthcare, and insurance industries,
have high requirements because they have a lot at stake to
lose. You will also lose in case of a breach of data.

8. 8
 It removes weak links and enhances access levels
40% of businesses that use cloud storage unintentionally
expose information to the public. Due to this, their
company's credibility had been undermined, giving its rivals
an advantage.
These leaks were caused by inadequate security practices
rather than by nefarious intent. Enforcing access rules on
employees by merely restricting access to data to those
who need it is one of the best practices for cloud security.
This makes it far more difficult for hackers to enter and
avoids mistakes that cause data breaches.

9. 9
Types of Cloud Services
The "cloud computing" refers to the method of accessing
resources, software, and databases through the Internet and
without regard to limitations imposed by local hardware.
Employing this technology allows businesses to scale their
operations with greater flexibility by transferring the majority or
a portion of the administration of their infrastructure to external
hosting companies.
Cloud computing operates in three environments:
 Public Cloud – These are hosted by CSPs and include
services like Infrastructure as a service (IaaS), Platform as a
service (PaaS) and Software as a service (SaaS).
 Private Cloud – These are hosted by or for a specific
company.
 Hybrid Cloud – This includes a combination of both private
and public cloud.

10. 10
Most cloud service providers try to build secure clouds for their
clients. The success of their business strategy depends on their
ability to stop breaches and preserve public and client
confidence.
Although, they can make an effort to prevent cloud security
vulnerabilities with the services they offer, but they have no
control over how customers use those services, what data they
add to them, or who has access to it. With their configurations,
sensitive data, and access restrictions, customers can weaken
cloud security.
To deal with such situations, CSPs provides cloud computing
services that are most often used and widely embraced, it
includes:
 Infrastructure–as–a-service (IaaS)
 Platform-as-a-service (PaaS)
 Software-as-a-service (SaaS)

11. 11
IaaS
“IaaS” or “Infrastructure-as-a-service” is a hybrid model, in
which businesses handle portions of their data and applications
on-site while depending on cloud service providers to handle
their server, hardware, networking, virtualization and storage
requirements.
Cloud services provide customers with the hardware and
remote communication frameworks that are needed to house
the majority of their computing, right down to the operating
system.
Only the basic cloud services are managed by providers. While,
clients are responsible for protecting everything that is layered
on top of an operating system, including programmes, data,
runtimes, middleware, and the OS itself. Clients must also
handle user access, end-user devices, and end-user networks.
These IT infrastructures, including storage, server, and
networking capabilities, are delivered to the clients via virtual
machines that are accessed over the internet.

12. 12
IaaS Architecture –
In an IaaS service model, a cloud provider hosts the structural
components that are generally present in an on-premise data
center. This includes servers, networking hardware,
virtualization as well as storage.
IaaS providers furthermore provide a variety of services to go
along with those infrastructure elements, some of them are:
 Comprehensive billing
 Monitoring
 Log access
 Security
 Load balancing, and
 Storage resilience, including backup, replication, and
recovery.
The expanding policy-driven nature of these services enables
IaaS users to adopt higher levels of automation and
orchestration for crucial infrastructure operations. For instance,
a user can build policies that direct load balancing to ensure the
availability and performance of the application.

13. 13
How does IaaS work?
IaaS users can gain access to resources and services using the
internet and can utilize the cloud provider's services to install
the remaining components of an application stack.
For example,
 The user may access the IaaS platform and construct virtual
machines (VMs) by logging in
 In each VM, install an operating system
 Install middleware (like databases)
 For workloads and backups, construct storage buckets
 And, deploy the business workload onto that VM.
Customers can then utilize the services of the provider to
manage disaster recovery, balance network traffic, track
expenses, monitor performance, and solve application
problems.
Independent IaaS vendors include Google Cloud Platform (GCP)
and Amazon Web Services (AWS). A company may decide to set
up a private cloud and become its own provider of
infrastructure services.

14. 14
Advantages:
 Cost Effective –
IaaS is the most cost-effective choice for organizations since
it eliminates the expense of infrastructure. Hardware and
other networking equipment do not need to be purchased.
In addition, IaaS has a pay-as-you-go pricing model that
allows users to pay only for services they use.
 Scalability –
An IaaS system can be scaled without the need for
hardware investment. This is due to the limitless availability
of cloud resources. The IaaS enables scaling up and down
based on the needs of the business. As a result, companies
may save both time and money. The users might scale
down the system once the services are no longer needed.
 Accessibility –
Today's workplace demands the most flexibility. In terms of
accessibility, in particular. IaaS enables employees of a
company to quickly access their files and other materials.
As long as an employee has an internet connection, they
may use virtual workplaces whenever they want.

15. 15
Disadvantages:
 Security –
IaaS users do not have control over the infrastructure. The
service provider is responsible for the infrastructure's
security. The amount of security offered might not always
be sufficient. As a result, it can make your system
vulnerable to attacks. The organizations in this situation
must be ready to face the loss.
 Customization –
The fact that IaaS is based on virtualization services makes
customization a difficult effort. This is due to the limited
amount of customization possibilities. Because of this, the
level of user privacy provided is not higher than it is with
alternative options.
 Unexpected Cost –
IaaS often costs less than purchasing the same services
bundled together. IaaS, however, might look even more
expensive than conventional services since the cost of
utilizing IaaS services sometimes rises abruptly. For
example, IaaS companies often implement a formula to
determine the amount of bandwidth you consume each
month. Even if you've never utilized additional services,
your bill might go up if your consumption goes up.

16. 16
IaaS use cases
IaaS is deployed in several situations. It aids in managing
variable storage demands and is beneficial for data backup,
storage, and recovery. IaaS makes it easier and less expensive to
set up test and development environments.
Additionally, businesses that employ Big Data frequently use
IaaS, which enables them to greatly enhance their processing
capability. The following are the top IaaS use cases:
Backup or disaster recovery solutions
In situations where demand is unpredictable or could
continuously rise, IaaS may be the simplest and most effective
method for enterprises to handle data. Additionally, enterprises
can avoid having to expend significant resources on managing,
complying with, and meeting the legal and regulatory
requirements for data storage.
Program Testing and Development
IaaS gives businesses flexibility in terms of selecting various test
and development environments. They are simple to scale up or
down based on requirements.

17. 17
Hosting Complex Websites
Even if IaaS isn't always appropriate for basic websites, it might
be the best starting point for more complicated web projects.
Especially for websites with large amount of traffic varies
greatly.
High Computing Performance
The implementation of supercomputers or clusters is typically
required for complicated tasks involving millions of variables or
calculations. IaaS may be a smarter alternative in this situation
because of its scalability. IaaS services are being taken into
consideration for networking as support as the complexity of
networks continually increases.
Big Data Analysis
The gathering of vast volumes of user data is one of the pillars of
brand building. Even more crucial than gathering this data is
processing it. IaaS can manage massive workloads and integrate
with business intelligence tools, allowing it to manage, store,
and analyze big data. By doing this, users may gain business
insights that they can utilize to develop relationships with their
clients and forecast emerging trends.
