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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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.

Cloud security has cut investigation time and now reveals threats faster but needs simpler oversight

When deploying AI applications, my key security concerns with Microsoft Defender for Cloud are data loss, leakage of data, and guardrails around the actual AI, and I am hoping that this is going to help me put those guardrails in place and identify data exfiltration. Microsoft Defender for Cloud has not helped me manage and secure multi-cloud environments, as we are 100 percent Microsoft and have not really got it in any other environment at all. I am not yet using the unified AI-powered security feature offered by Microsoft Defender for Cloud, but that is coming. I am not yet using the integrated XDR feature of Microsoft Defender for Cloud, but that is coming. I am not yet utilizing the GenAI threat protection features of Microsoft Defender for Cloud. That is also coming and a lot of that will come from learning it here. I have enabled the agentless scanning in my cloud environment with Microsoft Defender for Cloud. Assessing the impact on my workload protection without needing to install agents with Microsoft Defender for Cloud makes it a lot easier, but it also identifies a lot more, which puts more load on me sometimes. I would advise another organization considering Microsoft Defender for Cloud that it is the most logical route to follow if their whole ecosystem is Microsoft. It is easy to implement and it is very self-explanatory when doing it, making sense to just follow the steps as it is too simple, really. I would rate this review a 7.5 out of 10.

Quotes from Members

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

Pros

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

"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."

"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."

"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 scalability of the solution itself is unparalleled."

"The automated vulnerability detection aspect is most valuable."

"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."

"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."

More Amazon Inspector pros

"The solution has improved our organization in terms of benchmarking, our Secure Score has improved a lot, and we're compliant with particular benchmarks."

"Threat protection is comprehensive and simple."

"The features of Microsoft Defender for Cloud that I like the most are the regulatory compliance capabilities; these features have benefited my organization by improving our overall security posture."

"Using Security Center, you have a full view, at any given time, of what's deployed, and that is something that is very useful."

"Microsoft Defender for Cloud has helped us manage and secure our cloud environments, and having observability to vulnerabilities is important for us so that we can take actions against any threats."

"I would rate Microsoft Defender for Cloud a ten out of ten."

"Defender is a robust platform for dealing with many kinds of threats. We're protected from various threats, like viruses. Attacks can be easily minimized with this solution defending our infrastructure."

"Defender is user-friendly and provides decent visibility into threats."

More Microsoft Defender for Cloud pros

Cons

"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."

"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."

"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."

"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."

"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."

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

"The other point is that the reporting features of Inspector need improvement. For example, I am in an organization with millions of CVEs, and getting an overview of all this is challenging."

More Amazon Inspector cons

"Sometimes it's very difficult to determine when I need Microsoft Defender for Cloud for a special resource group or a special kind of product."

"It needs to be simplified and made more user-friendly for a non-technical person."

"Another thing is that Defender for Cloud uses more resources than for instance, CrowdStrike, which my current company uses."

"Azure is a complex solution. You have so many moving parts."

"As an analyst, there is no way to configure or create a playbook to automate the process of flagging suspicious domains."

"Sometimes if you do not have the resources in-house, it can be difficult."

"I felt that there was disconnection in terms of understanding the UI. The communication for moving from the old UI to the new UI could be improved."

"Defender is occasionally unreliable. It isn't 100% efficient in terms of antivirus detection, but it isn't an issue most of the time."

More Microsoft Defender for Cloud cons

Pricing and Cost Advice

"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."

"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."

"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."

"There are two different plans. We're using the secure basic plan, but we have used the end security plan as well. There are additional costs, but it gives us more functionalities compared to the basic plan."

"The licensing cost per server is $15 per month."

"Security Center charges $15 per resource for any workload that you onboard into it. They charge per VM or per data-base server or per application. It's not like Microsoft 365 licensing, where there are levels like E3 and E5. Security Center is pretty straightforward."

"This is a worldwide service and depending on the country, there will be different prices."

"I rate Microsoft Defender a three out of ten for affordability. The price could be a little lower."

"The cost of the license is based on the subscriptions that you have."

"We only use the free tier, so we haven't faced any pricing, setup costs, or licensing challenges."

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.
