PaaS (Platform as a Service) is a cloud service model that provides a platform for developing, testing, deploying, and managing applications in the cloud. PaaS includes the underlying infrastructure (servers, storage, network, etc.) as well as the middleware, databases, tools, frameworks, and APIs that are required for application development and delivery. Examples of PaaS are AWS Elastic Beanstalk, Azure App Service, Google App Engine, etc.

CASB (Cloud Access Security Broker) is what should be deployed to monitor and control the use of multiple SaaS-based business applications in a cloud environment. SaaS (Software as a Service) is a cloud service model that provides customers with access to software applications hosted on remote servers over a network or internet connection. SaaS can provide customers with convenience, flexibility, and scalability, but it may also introduce security risks such as data breaches, leaks, losses, etc., especially if customers have multiple SaaS subscriptions from different providers. CASB is a tool or service that acts as an intermediary between customers and SaaS providers. CASB can help to monitor and control the use of multiple SaaS subscriptions by providing features such as:

Visibility: CASB can provide visibility into what SaaS applications are being used, by whom, when, where, how, etc., as well as identify any unauthorized or suspicious activities.

Compliance: CASB can provide compliance with various laws, regulations, standards, policies, etc., that apply to SaaS applications and data, such as GDPR, HIPAA, PCI DSS, etc., as well as enforce them using rules or actions.

Security: CASB can provide security for SaaS applications and data by detecting and preventing any threats or attacks, such as malware, phishing, ransomware, etc., as well as protecting them using encryption, authentication, authorization, etc.

Roles and responsibilities are definitions or descriptions of what each team member or stakeholder is expected to do or perform in a project or process. Roles and responsibilities can help clarify the scope, authority, and accountability of each team member or stakeholder and avoid any confusion or duplication of work. The security team most likely forgot to implement roles and responsibilities when investigating a data breach, as they are all trying to do the same tasks but are interfering with each other’s work. Implementing roles and responsibilities can help improve efficiency and effectiveness, as it can ensure that each team member or stakeholder knows what tasks they need to do and how they need to coordinate with others.

CI/CD tools are software tools that enable continuous integration and continuous delivery or deployment, which are methods to frequently deliver software products to customers by introducing automation into the stages of software development. CI/CD tools can help a product-based company to transition to a method that provides the capability to enhance the product seamlessly and keep the development iterations to a shorter time frame, as they can offer the following benefits:

Faster and more reliable delivery of software products, as CI/CD tools can automate the processes of building, testing, and deploying code changes, reducing manual errors and delays.

Higher quality and performance of software products, as CI/CD tools can facilitate ongoing feedback, monitoring, and improvement of the code, ensuring that it meets the customer expectations and requirements.

Greater collaboration and communication among the development teams, as CI/CD tools can integrate with various tools and platforms, such as version control systems, code repositories, testing frameworks, and cloud services, enabling a seamless workflow and visibility across the software lifecycle.

Some examples of popular CI/CD tools are Jenkins1, CircleCI2, GitLab CI/CD3, and AWS CodeBuild4.

The best way to restrict access to a set of sensitive files to a specific group of users is to change the file permissions and ownership of the files. File permissions and ownership are attributes that determine who can read, write, execute, or modify the files. By changing the file permissions and ownership, the systems administrator can grant or deny access to the files based on the user identity or group membership.

Volume encryption is a type of encryption that protects data at the storage level by encrypting an entire disk or partition. Volume encryption can provide strong security for data at rest, as it prevents unauthorized access to the data even if the storage device is lost, stolen, or compromised. Volume encryption can also support automatic booting without manual intervention, as it can use a pre-boot authentication mechanism that does not require user input. Enabling volume encryption on the storage is the best way to resolve the issue of having an unencrypted database server containing PHI and PII, as it can protect the sensitive data without relying on VM encryption or a key management system.

The best option to reduce the latency issues for the marketing team that is primarily based in Europe when retrieving the marketing materials that are hosted on a public IaaS service is to integrate a CDN (content delivery network) solution to distribute web content globally. A CDN is a network of geographically distributed servers that cache and deliver web content to users based on their proximity and network conditions. A CDN can improve the performance and availability of web content by reducing the distance and hops between the users and the servers, as well as offloading the traffic from the origin server.
