More services are moving to the cloud as
businesses seek new ways to store data,
collaborate within organizations, and share
information with clients and partners.

Cloud services offer versatility and high levels
of redundancy, but solutions need to be
approached with an appropriate level of caution
to ensure that a largely decentralised system
remains secure.

To achieve this, hosting providers are required
to implement solutions that rely on robust cloud
computing infrastructure that is secured against
data loss and external threats.

Although cloud services are mostly decentralized,
they still rely on physical data centers to store
information and compute data. Because the data
center is one of the most important aspects of
cloud computing and infrastructure, it must
remain secure at all costs.

Data centers should take precautions to only host
equipment that is owned and managed by them, or
when it is necessary to on-sell data center
access, they should ensure that third party
cloud computing equipment meets the security
policies of the data center.

The software running on any piece of cloud
computing equipment should also meet strict
security policies. Computers used for cloud
services should run proven operating systems such
as industry standard Linux servers, which run in
most of the worlds largest cloud
infrastructures. Operating systems should have
adequate protection with strict access policies
and regular patch updates.

Software side security should also be implemented
in cloud services to allow for encryption and
sever side authentication. Authentication can
rely on technologies that enforce two-step
verification, as well as single session
authentication to prevent unauthorised sessions.
Encryption will help to protect data that is
being transmitted over public networks.

Because cloud services run on networks that are
both publicly and privately visible, network
security is an essential element to securing
cloud content. Everything from provisioning, to
access lists, and even maintenance teams need to
be maintained with strict care.

Provisioning and design should take in to account
the primary storage, database, and web servers on
a cloud service, and protect this with load
balancers and firewalls before they enter the
public domain within the network infrastructure.

Cloud infrastructure can be hosted in multiple
data centers, or on multiple pieces of hardware.
This will allow service providers to implement
robust backup and recovery systems.

This can be implemented through hard disk arrays
that replicate data on different drives, or by
backing up data at different sites.

Daily backups are a standard practice for most
cloud service providers, and they allow for
rollback after unplanned changes or faults, or in
the case of disaster recovery.

Because cloud services replace business functions
traditionally performed in-house, end users need
strong indicators of a commitment to reliable
service. Service providers can achieve this by
offering a competitive SLA, with a guaranteed or
best effort uptime.

Maintaining privacy is essential to the
reputation of a cloud service provider, and to
the sensitive data of an end user. Maintaining
privacy needs to be approached through multiple
channels.

Access to sensitive information including
customer records, as well as customer data itself
should be strictly controlled. Service providers
need CRM software to maintain customer
interactions in a controlled environment.

The above aspects of security will also
contribute to privacy. Encryption,
authentication, and log-in protection can all
help to secure the data of an end user, therefore
maintaining their privacy.

Firewalls can help to prevent unauthorized access
to a cloud computing system which can help
prevent privacy breaches and data loss caused by
malicious sources.

As more companies migrate storage, services, and
computing functions to the cloud, the
responsibility to address content security will
intensify for service providers. By adhering to
industry standard practices and implementing
strict internal policies, cloud computing service
providers will be able to maintain the integrity,
and the desirability of cloud services.
