Leveraging Security with CASB
Cloud McAfee

In the past several years, many organizations
have migrated their data centers to the cloud.
While many organizations have significant
investments in protecting data centers, those
same security measures will not translate to the
cloud. Cloud security requires continuous
monitoring, visibility, and focus on identity
and access. It is ultimately a shared
responsibility of all users that access the
cloud, whether it is customers, partners, or
internal employees. Solutions such as McAfee
CASB, MVISION Cloud, can help organizations
address security in the cloud, enforcing
policies, monitoring, and visibility. What is a
CASB and What Does it Offer? A Cloud Access
Security Broker (CASB) is an intermediary
between cloud service providers and users. It
allows organizations to extend the reach of
their existing security policies to the cloud. A
CASB serves as a place to enforce policies and
apply those policies to everything that your
organization does in the cloud, regardless of
what devices are being used. CASB's offering
includes data loss prevention, malware
detection, cloud governance, threat prevention,
data encryption, SSO IAN integration, and
contextual access control. Cloud Access Security
Brokers have become a vital part of
cybersecurity because it allows businesses to
protect corporate data while using the cloud.

Maintaining the 4 Pillars of Cloud
Security Visibility is a key component of cloud
security. Organizations will have many employees
accessing many applications in different cloud
environments. With the large amount of cloud data
being used every day, cloud data becomes outside
of the view of IT monitoring. This data is no
longer compliant with company security and risk
policies without proper cloud security. To better
protect data and users, a CASB provides
visibility into cloud usage. During cloud
discovery analysis, a risk assessment will be
provided for each cloud service in use. This will
allow security professionals to understand where
user access should be further restricted, and
where user access should be allowed. Visibility
helps shape what controls are necessary to better
protect data in the cloud. Compliance is an
essential pillar of CASB. A driving factor for
many businesses to use CASB is to enforce
security in the cloud. If sensitive data is
stored in the cloud without essential security
protection, that data is at risk of being lost or
stolen. Essential cloud security tools are
necessary to maintain compliance regulations
such as PCI DSS, ISO 27001, NIST 800-171, HIPPA,
and more. A CASB will determine which areas of
an environment are at the highest risk and take
necessary action to protect data and provide
direction. Data Security is another pillar of
cloud security. Since the cloud allows for
seamless movement and sharing of data among
individuals, protecting data can become more
costly and time-

consuming without the proper tools. Traditional
on-premise solutions are not designed to protect
the data in the cloud, a CASB is required to
provide visibility to the data that is moving
throughout the cloud. Data leaks can be minimized
by integrating traditional DLP (data loss
prevention) tools and a CASB. Threat protection
is the last pillar of CASB. A CASB can be used
to pinpoint malicious behavior to minimize threat
protection. McAfee CASB utilizes machine
learning and user entity behavior analytics
(UEBA) technology. This allows the tool to
detect and remediate threats as they happen. A
CASB can use adaptive access control and dynamic
malware analysis to block malware and prevent
threats. Next Steps Whether your organization is
first migrating data in the cloud, or you have
fully shifted to the cloud, cloud security should
be held as a priority. At Aurora, we can help
you find a cloud security tool that works best
for your organizations goals. We offer
