What would be the most appropriate security mechanisms for IaaS, PaaS, and SaaS service models?
IaaS is a cloud computing architecture that delivers computing, network, and storage resources via the internet using a scalable subscription model. It is a basic cloud platform that may be used to develop or supplement platforms as a service (PaaS) and SaaS.
Security Mechanisms for IaaS:
Cloud Security Gateway: It gives control and visibility over cloud resources, such as monitoring user activities, detecting cloud malware, encrypting data, and avoiding data loss. They keep an eye on the IaaS for misconfiguration and unsecured data, as well as file access rights.
Cloud Security Poster Management: It inspects the IaaS cloud environment for all security and order concerns, providing both human and automatic remedies.
Cloud workload protection platforms: It defends against malware assaults, identifies containers and workloads, and secures unmanaged containers.
PaaS stands for Platform as a service, it is for developers who want a platform where the application can be created and deployed, PaaS assists the developers who create a custom application by providing them the hardware, operating system, middleware, and database. In this model, users do not have control over the infrastructures of the cloud.
Security Mechanisms for PaaS:
Penetration testing: It assists in identifying all vulnerabilities or gaps before an attacker can exploit them.
Detect and prevent all attacks automatically: Deploy a real-time and automated protection solution. PaaS subscribers may utilise the security solutions currently offered on the platform, or they can look into any third-party choices that can meet their needs.
Regular Scanning: Scan all programmes for security vulnerabilities on a regular basis to see if there are any dangers, and schedule this scanning to run automatically daily or at a certain frequency.
SaaS stands for software as a service, and it allows you to run an application in the cloud without having to instal it on your local PC. Devices such as smartphones, laptops, and tablets may access the programmes via a web browser.
Security Mechanisms for SaaS:
Data loss prevention: The detection system of DLP looks for specific keywords in the text to determine whether your organization’s sensitive data is being leaked. There are some SaaS APIs that you can implement in your development to keep track of how many times your application is opened, the number of logins, and so on.
Keep Backups: Just because the programme is operating in the cloud doesn’t mean you shouldn’t preserve backups. You should keep backups so that if a problem arises, you can correct it. Make sure to include all your files’ metadata, since it handles all permissions and uses rights.
Password: password should be updated on a regular basis, and strong passwords should be used each time so that cracking is difficult.
