Cloud Security Consulting Services

“Because you’re building systems on top of the AWS cloud infrastructure, the security responsibilities will be shared: AWS manages the underlying infrastructure, and you secure anything you put on the infrastructure or connect to the infrastructure.”
- Amazon Web Services

Businesses are moving mission-critical applications to the cloud at a rapid pace. The cost savings and other benefits simply are too persuasive not to move to the cloud. So why do organizations hesitate? Analyst studies cite security concerns as the number one inhibitor of moving sensitive applications to the cloud.

NetSentries, as part of its Pre-Cloud Security Consulting, performs risk assessment of the existing on premise IT infrastructure, policies, procedures, operations etc. in order to aid the customer to choose the type of cloud design based on the business impact and risk exposure.

As the trusted Information Security Partner in your Journey towards Cloud, our comprehensive Cloud Security Consulting portfolio includes Pre-Cloud Security Consulting, Cloud Security Solutions Design & Optimization and Cloud Security Assessment Services.

Cloud security may be a new concept, but the underlying principles of building security remain the same

Our experienced consultants will help you to design and develop the cloud solution with proper data leakage protection.

Cloud Security Assessment Services

Security Assessments are third-party audits of cloud service providers or assessments of on premise cloud systems based on industry standards. Traditional security assessments for infrastructure and applications and compliance audits are well defined and supported by multiple standards such as NIST, ISO and CIS. NetSentries has developed a proven internal framework for the current state assessment of the client cloud environment.

The purpose of the Cloud CSA Service is to analyze a Customer’s cloud environment end to end and provide higher visibility into their existing security posture across a wide field of view. This is a broad security assessment for those organizations that need a macro view of their environment to ensure all of the Cloud industry recommended security best practices are implemented, vulnerabilities are fixed, security controls are in alignment with the Information Security Policy and Compliance standards, Threat monitoring is effective, Policies and Standards are well developed and maintained, Access control and Content Filtering is effective, Risk Register is properly maintained, Logging and Auditing is proper, Incident Response measures are well developed and implemented, Patch Management is up to date, Security Architecture is flawless and End Point and Network Security Controls are properly implemented.

The regulatory environment has become more complicated because organizations often find themselves required to comply with multiple regulations and industry mandates. As new threats emerge, regulations and standards continue to increase in number and complexity. Now, many laws carry penalties for data breaches and for not meeting timely notification of those affected. These areas of concern are addressed as the cloud environment continues to evolve with the utilization of encryption methods are incorporated as organizations define their strategy for cloud control. The benefits of security frameworks are to protect vital processes and the systems that provide those operations. A security framework is a coordinated system of tools and behaviors in order to monitor data and transactions that are extended to where data utilization occurs, thereby providing end-to-end security.

The leading frameworks and guidelines to meet regulatory requirements are as follows:

      Cybersecurity Framework that is based on the NIST framework that can be applied to any industry. The cybersecurity framework is employed to build an information security program. (NIST, 2013, 2014; SANS, 2016).

     Control Objectives for Information and Related Technology (COBIT) aligns IT with strategic business goals. This framework is commonly used to achieve compliance with Sarbanes-Oxley (ISACA, 2015).

     International Organization for Standardization (ISO) is a broad information security framework applied to all types and sizes of organizations

     The Payment Card Industry Data Security Standard (PCI DSS) is used by merchants for credit card processing.

     Cloud Security Alliance (CSA) provides comprehensive guidance on how to establish a secure baseline for cloud operations. CSA maintains the Security, Trust & Assurance Registry (STAR) cloud provider registry

Our Approach:

The first step utilizing a framework is to determine what industry-specific compliance requirements apply to the business. Cross-reference tables are available for overlapping security controls to meet compliance requirements across the multiple frameworks that apply to an organization. Implementing a comprehensive framework prevents an adverse impact on the organization by enabling resilience and improved defenses. Frameworks must be utilized in an appropriate context. Standards are a generic solution to an extremely individualized problem set. Cybersecurity connects directly to business strategies and operations and must be tailored to the organization.

The audit methodology utilizes an information-centric approach to review data, processes, and provide applications for clouds, hybrid, and on-premise environments employed by the organization.

Cloud Controls and Policies Review:

NetSentries assesses cloud environment by conducting a controls assessment utilizing frameworks from bodies such as the Cloud Security Alliance (CSA), Cloud Controls Matrix and the US National Institute of Standards and Technology (NIST SP 800-144). This will help organizations to learn whether the Cloud Service Provider has solid controls including adherence to any legal, statutory or regulatory compliance obligations among many areas including:

     Application and Interface Security
     Business Continuity Management and Operational Resilience
     Change Control and Configuration Management
     Data Security and Information Lifecycle Management
     Datacenter Security
     Encryption and Key Management
     Governance and Risk Management
     Human Resources
     Identity and Access Management
     Infrastructure and Virtualization Security
