Cloud Security

"In fact, Gartner predicts that, through 2020, 95 percent of cloud security failures will be the customer’s fault." 

                                                                             - Gartner

Majority of the infrastructure refreshes are about cloud technology to ensure a safe and secure way for the business operations. The safety of these assets is a key consideration for any management to show commitment to securing their supply chain, customer information and/or their corporate information. Our Cloud Security Service can help you assess your risks and the relevant risk mitigation steps to minimise the attack surface.

Irrespective of the cloud service model in use (Iaas, Paas, Saas), security validation is important at one or multiple stages of business lifecycle of any asset. Defendza offer security assessments of applications, infrastructure and/or configuration reviews hosted at AWS, Azure, Skyscape, Virtualized environments such as VMWare, Hyper-V.

We have a dedicated security assessments FAQ section. Read it here.

Reasons for Cloud Security Assessments?

Cloud applications and technologies are increasing exponentially to address scalability, speed and reliability issues over on-premise setups. A small misconfiguration such as permissions weakness could expose a company's database or other service putting data in full internet view. Defendza help businesses to ensure their cloud assets are secure before being adopted by the users.

Our Approach

Our cloud security offerings are based on extensive methodlogy we have developed with years of experience working across different sectors. It's very important that a cyber security consultancy follows an approach that delivers right returns on your investment. At a high level, our approach towards cloud security assessments is as follows:

Step. 1
Identity and Access Management

This phase involves reviewing identity and access management related controls. Generally, these include checks on the use of higher privilege accounts, use of MFA, password policy, IAM policies, access keys and credentials usage policies. 


Step. 2
Review Authentication Architectures

Authentication and authorization problems are prevalent security vulnerabilities. Most mobile apps implement user authentication. Even though part of the authentication and state management logic is performed by the back end service, authentication is such an integral part of most mobile app architectures that understanding its common implementations is important.


Step. 3
Network Security

This area involves checks around network security controls such as ingress, egress rulesets, flow logging, traffic restrictions, and least access privileges.


Step. 4
Logging API Calls, Events

All major cloud service providers offer web services that record API calls for tenant account. This information contains various parameters such as API source, calls details, requests/response elements. This phase includes a review of API calls for an account, log file validation, encryption at rest, access checks if logs are restricted from public view and access logging, configuration management and monitoring options.


Step. 5

The monitoring phase is one of the critical tasks responsible for alerting relevant contacts during an incident. This involves reliance on the logging and related configuration parameters to ensure right metric filters are in place. These reviews include checks for real-time monitoring configuration, alarms for any changes made to access control lists, security policy/groups, routing tables, and related parameters.
