AWS vulnerability management is the continuous process of identifying and managing vulnerabilities within your organization’s AWS environment. Vulnerability management in AWS also includes reporting and remediation of detected security risks and is a vital practice in good AWS security management.
This article will provide you with an in-depth understanding of the processes, steps, benefits and tools that come under AWS vulnerability management.
Processes That Come Under Vulnerability Management In AWS
Here’s a list of the processes that come under AWS vulnerability management aiding in the efficient identification and mitigation of flaws within the AWS environment.
Vulnerability scans are automated tests carried out of ease of use and quickness. They detect any vulnerabilities present in the assets through a quick scan which after which an automated vulnerability scan report is generated for the customers.
Vulnerability Assessments are a bit more comprehensive when compared to scans, it involves vulnerability scans which is later evaluated and prioritized according to their potential impact. This is then mentioned in the vulnerability assessment report along with remediation measures and PoC videos for the resolution of each vulnerability.
The most comprehensive process under AWS vulnerability management, penetration tests are great for assessing an AWS environment in an indepth manner. However they take time and can be costly. Therefore it is carried out once or twice a year to find and exploit and vulnerabilities to understand its true impact.

Remediation And Patching
One of the most important processes within AWS vulnerability management is the remediation and patching of the vulnerabilities detected and identified. Patching can be done using automated tools or if they are extensive, then carried out manually.
AWS Vulnerability Management Best Practices
Here are some of the best practices to follow when maintaining you AWS platform.
Continuous Vulnerability Scanning
Continuous vulnerability scanning helps greatly with vulnerability management in AWS. A good AWS cloud vulnerability scanner should be able to continuously scan and detect even the most minute of vulnerabilities.
It should also have an extensive vulnerability database so that all vulnerabilities are rightly assessed. The tool should also have features like behind-the-login scans, detection of logic errors, false positive detection as well as ensure that are no false negatives.
Integrating vulnerability scanning into the development allows for continuous scanning for vulnerabilities throughout the progress of the application.
Such integration also allows AWS customers to be continuously compliant with the important regulatory standards they need to abide by like GDPR, ISO 27001, HIPAA, and PCI-DSS.
Regular Penetration Testing
Regular pentests are an excellent practice for AWS vulnerability management. They go a step further from vulnerability scanning by exploiting the found vulnerabilities to properly assess the extent of damage that could occur from such an attack in real-life.
Ensure that your applications and security measures within the AWS environment are regularly updated to reduce the chances of any security gaps and the potential risk of exploitation.
Timely updation allows the patching of any vulnerabilities with your software in the AWS platform.
Using AWS Services
AWS provides a variety of security tools such as AWS Security Hub, AWS Inspector, AWS Identity, and Access Management among others, all of which play a crucial role in helping you maintain the security of your AWS environment without any compromise.
Incident Response Plan
It is vital to create and implement an incident response plan since in the event of a security incident it helps shorten the response time, and speed up the recovery process as well. The plan should include steps for the identification and resolution of the incident with communication measures and recovery plans.
Major AWS Security Services Provided by AWS
Amazon Web Services provides a lot of tools to heighten the security measures within their platform. Customers can choose and use them based on their requirements. Few of the important ones are:
AWS Security Hub
AWS Security Hub is a cloud security posture management service that enables the automation of security checks for best practices and aids with the acceleration of mean-time response through automated response and remediation.
It performs a quick analysis of the attention-demanding security alerts across all regions and accounts within your AWS platform. It consolidates these findings to a standard format to allow you to take quicker action.
This service in tandem with others provided by AWS like AWS Inspector, Amazon Macie, and more allows you to have a 360-degree view of your AWS security.
This automated vulnerability management service helps by performing continuous scans of the automatically detected AWS workloads for vulnerabilities and unintentional exposures. After a few easy steps to enable its services, AWS Inspector can be used across all your AWS accounts.
Once enabled, it discovers EC2 instances and images within the Amazon ECR (Elastic Container Registry) and starts assessing them for flaws or areas of exposure. It provides a highly contextualized risk score that factors in a lot of criteria through the correlation between CVEs, network accessibility, and exploitability.
AWS Shield is one of the AWS security services that provide protection to the infrastructure such as network connections. It provides protection against DDoS attacks thus securing the applications running on the AWS cloud.
AWS Shield is of two types: Standard and Advanced. Standard Shield protects against basic threats like common network DDoS attacks. Advanced Shield goes above and beyond the standard services by also providing identification and prevention of large-scale DDoS attacks, integration, and closely monitored visibility of attacks.
AWS Identity And Access Management
This service allows one to define and set parameters for access with specific credentials, and to scale the privileges as and when required. It allows you to fine-tune the access and authorization allowing you to decide which individuals, groups, or roles can access certain information.
The features offered by AWS IAM include:
- AWS Single Sign-On
- Manage permissions for single accounts
- Manage single-account roles
Steps in AWS Vulnerability Management
The below detailed are the steps taken in AWS threat and vulnerability management.
The initial step in a well-implemented AWS vulnerability management program involves the identification of vulnerabilities. This is done using comprehensive vulnerability scanners capable of detecting a wide range of vulnerabilities.
This step results in the detection of known CVEs, and vulnerabilities mentioned in standard frameworks like the OWASP Top 10 and SANS 25. Your assets are mapped out in detail and scoured for any flaws, gaps, or vulnerabilities that pose a threat to your cloud environment.
It is vital to schedule such scans during slower traffic times as it can cause disruptions in regular operational conditions.
The identification of vulnerabilities is followed by their matching to the vulnerability database at hand. They are assessed further to understand the extent of their threat levels.
The evaluation of identified threats aids in their prioritization according to the mentioned risk levels posed by each vulnerability. This allows a team to understand which of the vulnerabilities need to be fixed immediately and make a diligent plan in lieu of it.
The most common system used to identify the extent of threats posed and prioritize them is the CVSS system. Based on the CVSS scores, potential threat impact, and other contextual data, the vulnerabilities are prioritized for patching.
The AWS vulnerability testing report has details such as the executive summary of the scan, the methods employed to detect vulnerabilities, and the vulnerability database used as a standard reference.
Along with this, the vulnerabilities found are listed and extensively explained with their CVSS scores as well as possible remediation measures.
Once the vulnerabilities are assessed according to the risk they pose, it is now time to respond and fix each flaw found. This is done based on the data from the risk assessment.
Based on the threat level there are general measures that can be opted for to create a viable and healthy security solution for the cloud. These measures include:
- Fixing the highest risk posing vulnerabilities immediately based on their risk severity is known as patching.
- When fixing the problem at hand isn’t a feasible solution, then the risk posed by them is managed thus reducing the chances of them being exploited. This is known as mitigation.
- Sometimes if the vulnerabilities discovered are not critical or have a low CVSS score, they are left as such since the chances of them being exploitable are minuscule.
The final step is to avail a re-scan to ensure that your AWS platform is safe from the initially found vulnerabilities. This assures, builds, and increases trust for your existing and potential clients. It also increases your reputation as a safety-conscious provider and increases trustworthiness.
