Architecture Overview

An in-depth overview of our architecture.

Architecture

The architecture seen below supports the object flow as described in the Object Scanning section both in a single region as well as across all regions supported. The Console region will have all components deployed to it. Any additional regions only require the scanning Agent(s) which will report back to the centrally located Console. In addition to this high-level architecture, you can get more details on routing and the public access required on the Deployment Details page.

Platform Services

While many services are used (ECS Fargate, App Config, CloudWatch, CloudFormation, DynamoDB, SNS, SQS, IAM) to deliver the Antivirus for Amazon S3 solution, two will be called out here. CloudWatch and IAM are leveraged for logging and permissions respectively. These are the usual questions we get from customers:

1. How do I check the logs?

2. What are you doing behind the scenes (permissions wise)?

We wanted to make sure you had those bases covered with the information below.

Log groups for ECS

As of version 6.06 we enable ECS logging by default. These logs will be shown in the following log groups.

For each of these log groups you will see your seven character application ID in the title of each log group as noted below by the AppID between the ECS and type of ECS service the log is for.

ECS.AppID.API

Log groups related to the ECS API Agent Service

ECS.AppID.Console

Log groups related to the ECS Console Service

ECS.AppID.AVEvent

Log groups related to the ECS AV Event Agent Service

ECS.AppID.DCEvent

Log groups related to the ECS DC Event Agent Service

IAM Permissions Review

We have been able to simplify the management and delivery of the solution such that there are very few tasks the administrator is required to perform inside the AWS Console. As a result, the Console and EventAgent have a number of permissions assigned to them within their respective roles to allow them to perform the actions needed on your behalf. In all cases, we went with a least privilege model wherever possible. There are a few instances where we have assigned * when it is required. Below you will find a review of the two IAM Roles we create and assign to the Console and scanning Agents.

Please review and Contact Us if you have any questions we can clear up for you.

The permission descriptions below follow the format:

- system-name
    - permission 1
        - reason it is needed
    - ...
        - reason it is needed
    - permission n
        - reason it is needed

Scan Engines

Antivirus for Amazon S3 has been built in such a way that the underlying scanning engine can be exchanged with other scanning engines as needed or desired. There are three engines included out of the box:

• Sophos - a well known enterprise solution that offers speed, great accuracy and large file scanning

• CrowdStrike - a proven component of the CrowdStrike Falcon platform which uses market-leading machine learning technology and CrowdStrike’s massive corpus of malware samples to scan for malicious code

• ClamAV - a widely used open source antivirus engine for detecting trojans, viruses, malware & other malicious threats.

Engine	Update Frequency	Max File Size	Speed	Type	API Endpoint
	Agent checks every 15 minutes vendor typically updates 4 times per day	195 GB 5TB with extra large file scanning File Types	faster engine; refer to Sizing Discussion	Signature Based	Yes
	ML Model updated by vendor 3 times per year	20 MB File Types	Average scan time typically below 500 milliseconds; Sizing details coming soon	Signature-less, Machine Learning Based	Yes
	Agent checks every hour vendor typically updates once per day	2 GB File Types	good performance engine; refer to Sizing Discussion	Signature Based	Yes

Antivirus for Amazon S3 has the ability to use multiple scanning engines configured serially to ensure the highest level of efficacy and protection. Antivirus for Amazon S3 updates virus definitions as defined above as well as with each reboot / new spin up.

If you are a scan engine vendor and would like to partner with us to get your engine integrated into our solution or if you are a customer who would prefer another engine, please Contact Us.
