Preventing Threats and Risk in Cloud Environment
An industry report shares that
approximately 80% of companies surveyed had experienced at least one cloud data
breach in the last one and a half years. These breaches were the result of
misconfiguration of cloud security controls and inadequate visibility into the
organization’s cloud security posture in terms of risk, threat and vulnerabilities.
Enterprise security usually takes
a backseat while organizations are planning for their cloud journey as typically
migration of workloads to cloud starts first, and security is thought about
afterwards. Security should go hand-in-hand with the cloud journey and migration
strategy to ensure cloud is secured at the perimeter, middle and end layer; while
data is also secured at all touch points at rest and/or in transit.
With more and more organizations modernizing their Infrastructure and moving
their obsolete servers and apps to the cloud, the use of Kubernetes is on rise.
Zensar strongly recommends securing Kubernetes pods using a Kubernetes WAF solution,
as a native solution is not enough to keep your data secure from ever changing
and evolving malicious threat actors.
As they migrate to cloud, organizations will benefit from faster time to
market, cost savings, etc., however their security challenges will increase as
the incumbent users who were insiders turn into outsiders. IT administrators and malicious actors now
have identical access to publicly hosted workloads using standard connection
methods, protocols and public APIs. As a result, identity has become a new
perimeter, and Zero Trust access and automated response is imperative for securing
your cloud
infrastructure.
A defense in depth (DiD) approach with security controls including DDoS
prevention, next-gen firewall, IDS/IPS, web content filtering, WAF, anti-malware,
encryption at rest and in transit, etc. still hold their value as was the case in
traditional data centers and they are a necessity even now. However, now there
is also the need to develop a sound vulnerability and cloud security posture management
program.
Most organizations today are using SaaS based applications which provide benefits
from the efforts and cost needed for administration, maintenance and
development of applications developed in-house. Organizations still struggle to
safeguard themselves from threats and risks such as ransomware attacks, data exfiltration, limited visibility over
sanctioned and unsanctioned IT, and anomalous user behaviours. Zensar advises using
a cloud access security broker (CASB) solution to overcome these challenges.
As our team of security experts observes the increase in sophisticated attacks
targeting business critical information, our recommendation to clients includes
having advanced and enhanced levels of granular cloud security framework, which
provides a 360-degree view of all cloud security aspects. To overcome these
challenges and concerns, Zensar offers comprehensive cloud
security coverage based on its CloudSecure framework. This
framework is guided by our 3C’s principles of Comply, Control and Contain which
enables mapping of security controls as follows:
·
Comply – Includes configuration hardening, cloud compliance and policy
management
·
Control – Includes authentication, access control, MFA, data discovery, asset
and data classification, encryption and key management
·
Contain – Includes vulnerability management, perimeter and endpoint security
controls, monitoring and analytics
If your organization is moving towards migrating to the cloud, or you
are doubting the security of your existing cloud infrastructure to combat
today’s growing digital threats, it is time to think about a transformation
strategy including cloud security solutions based on Zensar’s CloudSecure
framework.
