Overview of Cloud Security Scanner: What do AWS, GCP, and Azure Provide?

Cloud security scanners are tools that help companies discover any flaws and loopholes within the cloud platform they make use of for data storage and transmission. However, it not only scans for these weak points but rather also points out remediation measures to strengthen the security system too. 

An ideal cloud security scanner should have the following features: 

  1. Continuous Automated Vulnerability Scanning
  2. Regular Penetration Testing
  3. Compliance-specific scans

Why Cloud Security Scanners Are Needed?

The above-mentioned features together ensure that your company’s services remain the best in terms of protection and compliance.

  1. Cloud security forms a vital part of cloud computing, as such, due importance is to be given to its security since it too is susceptible to malicious attacks and data breaches. Not doing so can lead to the tarnishing of your company’s reputation.
  2. Compliance with sector-specific security standards like HIPAA, ISO 27001, PCI-DSS, and more are crucial since it determines and showcases the quality of your company. Additionally, not meeting compliance requirements can lead up to hefty punishments and fines.
  3. Cloud security scanners can be integrated into the CI/CD pipeline. This means that any possible flaws can be diagnosed and remedied at the development stage of projects.
  4. Cloud security scanners can help customer organizations keep up with the shared responsibility model of security opted by cloud platforms like AWS. With this model, the maintenance of security is the shared responsibility of the customer and the cloud service provider.

How Do the Scanners Help With Cloud Security?

  • Cloud security scanners provide cloud security assessment and protection at every stage of the cloud application development process. This allows the shift from DevOps to DevSecOps thus enabling the integration of vulnerability scanning into every step throughout. This allows the early detection of flaws which can then quickly be fixed to move further in development. 
  • Continuous automated vulnerability scanning helps ensure that there is a periodic check of the cloud platform for weaknesses in security. These automated scans check for known vulnerabilities and other CVEs based on intel or well-established frameworks like NIST, OWASP Top 10 Risks, and SANS 25. 
  • Regular Penetration Testing refers to hacker-style testing of the defenses put up by one’s cloud security. Vulnerable areas are penetrated to see the extent of possible damage and assess the amount of data that would be compromised from such an attack. 
  • Compliance-Specific Scan scans for certifications like PCI-DSS, HIPAA, ISO 27001, and SOC2 help maintain some internationally accepted standards that make your organization stand out among others in terms of service. It also plays a vital role in ensuring the smooth functioning of your company in terms of cloud security.

Top 3 Cloud Platforms That Utilize Cloud Security

This section will detail the top 3 cloud service providers which are Google Cloud Platform, Azure, and Amazon Web Services. These three major cloud providers provide a variety of data storage, transmission, and networking options. 

Google Cloud Platform Security Scanner

This range of cloud computing services is provided by Google, and it includes data analytics, storage, transmissions, and management services. Google Cloud Platform Security Scanner provides a venue not only for Software-as-a-Service applications but also for Infrastructure-as-a-Service (IaaS) models too. 

As a part of security for its customers it also has a security command center with the following features: 

  • Threat Detection

This refers to the detection of risks and associated threats through constant and continuous monitoring. There are two types of threat detection, container, and event-based detection. 

Container threat detection refers to finding threats by monitoring large suspicious files, images, and attempts to gain access remotely. Secondly, event threat detection refers to the immediate detection of threats through monitoring the cloud using detection logic. Both types provide alerts for the detection of threats.

  • Security Scanner

This application scans web applications and other services running on Google engines. It crawls through applications and carries out security tests for vulnerabilities like cross-site scripting and more. This scanner helps identify flaws in the data and services on the Google cloud before they can be exploited by hackers with malicious intent. 

Microsoft Azure Cloud Security Scanner

Microsoft Azure was specifically made for designing, building, releasing, and managing a variety of applications. Its services include computation, networking, and data management that offers storage redundancy across multiple data centers thus ensuring the safety of information. 

Azure is known for its extensive networking capacities. This is because it can support site-to-site virtual network connections from different regions. It also has a Security center that manages all Azure security concerns. Its features include: 

  • Vulnerability Management

Azure penetration testing services for virtual machines, database servers, networks, and web applications as well. If virtual machines do not have their own security management system Microsoft Azure deploys Qualys vulnerability scanner for security management. 

  • Vulnerability Assessment

Microsoft Azure’s security center does not directly conduct vulnerability assessments but instead checks whether the machines and VMs have deployed vulnerability assessment tools.

  • Defenders for Container Registries

This tool scans container images added to the Azure container registry that were either added recently or pulled in the previous month. The scans are automatic and they find known vulnerabilities and CVEs. The report provided gives extensive details on the vulnerabilities, their risk severity scores, and remediation measures.

AWS Cloud Security Scanner

AWS was by Amazon is considered one of the best pioneering cloud computing services that set the gold standard for all other cloud services. It offers a wide range of IaaS services that includes storage, networking, computing, and content delivery. 

It also provides tools for service management and resource monitoring and smooth data collection among others. It is one of the largest providers of cloud services that significantly contributes to company enhancement and growth. 

For security purposes, AWS provides customers with AWS Security Hub. This is a central console for managing all things security-related. It identifies security issues according to two main categories. Here are its features:

  • The first category of security issues compiled are called Findings, this includes security issues from various regions like third-party services and certain customizations. These findings are then crossed checked against all AWS services to find their severity. 
  • The second is a collection of specific findings which are termed Insights. These are security issues found that have a high-risk probability and need to fix as soon as possible. The AWS security hub provides an in-built library of such findings and insights or they can also be customized.
