Automated insights streamline data security assessment

For Amazon Inspector, we have many EC2 or virtual machines deployed inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages. As we progress with time, this package needs to be updated for security enhancement, which requires us to uninstall the package, install the new version, and then we should be fine. However, the challenge comes with how to scan all our EC2 instances for security vulnerabilities, which is currently managed by Amazon Inspector. Amazon Inspector can scan EC2 instances or ECR, which is the ECR registry where we can save artifacts Docker images. Amazon Inspector can also scan Docker images uploaded to ECR for Elastic Registry service, and it can scan databases and S3 based on the latest updates. I noticed this from a couple of months ago, and it provides huge benefits for security. Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are causing security concerns. Amazon Inspector can list these security concerns and offer guidance on how we can remediate it by updating the package to a specific upper version or something similar.

Centralized security testing has improved vulnerability remediation and compliance reporting

I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It is scanning the whole repository for any sort of vulnerabilities, so it allows us to be more confident in our DevSecOps and not put a lot of folks or attention to it."

"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."

"The automated vulnerability detection aspect is most valuable."

"The assessment reports provided by Amazon Inspector have helped me in identifying security vulnerabilities in my cloud applications by giving us a nicely designed dashboard that provides all the security information we need to work on remediation."

"The findings dashboards are neat and easy to understand, offering clear demarcations for different types of findings and detailed insights into specific vulnerabilities and their associated instances. It is not a place where everything is dumped together. It offers an easy-to-understand layout."

"My experience with AWS technical support is very good, I didn't face any specific challenges, and even the documentation of AWS is good for both Microsoft, which is Azure, and AWS."

"The scalability of the solution itself is unparalleled."

"The vulnerability discovery is valuable, and they also rank those vulnerabilities for you. So, you could rapidly attack some of the higher, severe vulnerabilities as they pop up, if they do pop up."

More Amazon Inspector pros

"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."

"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."

Cons

"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."

"One area for improvement in Amazon Inspector is the automation aspect."

"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."

"One major area for improvement is remediation. My team works on remediating findings over time, likely using available patches. However, easier integration with Amazon's patching services would be very helpful."

"It has a limited scope. So, AWS Inspector primarily focuses on the security of the EC2 instance. So, if your architecture includes other AWS services, then you may need to use additional tools for your comprehensive security assessment. So that is one con. Another is, like, we have a dependency on agents."

"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."

"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."

"There isn't too much to improve right now. Scanning on demand or as a part of the pipeline versus a post pipeline solution would be good, but it is not a deal breaker by any means."

More Amazon Inspector cons

"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."

"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."

Pricing and Cost Advice

"It's priced according to market standards for its services."

"It is scaled as you go. There are probably a certain number of scans per month, and there are tiers. If you're under a certain tier, it is free. The second level is pennies, and then all the way up to like a million. So, it has a tiered pricing program. They're pretty good with your initial scanning, and there is room to scale based on being affordable, but it is fairly cheap. There are no additional costs. They pretty much think about it as a pay-per-scan type model."

"The lowest cost would be around $10 for a few small accounts, however, for thousands of accounts, it could be around $5000 to $6000 dollars per month."

"The pricing is very transparent and clear."

Overview

Amazon Inspector is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS. Amazon Inspector automatically assesses applications for exposure, vulnerabilities, and deviations from best practices. After performing an assessment, Amazon Inspector produces a detailed list of security findings prioritized by level of severity. These findings can be reviewed directly or as part of detailed assessment reports which are available via the Amazon Inspector console or API.

Amazon Inspector security assessments help you check for unintended network accessibility of your Amazon EC2 instances and for vulnerabilities on those EC2 instances. Amazon Inspector assessments are offered to you as pre-defined rules packages mapped to common security best practices and vulnerability definitions. Examples of built-in rules include checking for access to your EC2 instances from the internet, remote root login being enabled, or vulnerable software versions installed. These rules are regularly updated by AWS security researchers.
