Custom feeds
You can supplement the Prisma Cloud Intelligence Stream with your own custom data, including:
- Banned IP addresses.
- Malware signatures.
- Whitelisted CVEs.
For each data type, you can add individual entries to a table from the Console UI, bulk upload a list from a CSV file, or submit a JSON object via the Prisma Cloud API.
Supplementing the IP reputation list
You can supplement the Prisma Cloud Intelligence Stream with your own list of banned IP addresses.
Update your custom IP reputation list from the Console UI.
You can specify one entry at a time, or do a bulk upload from a CSV file.
The maximum file size is 20MB.
The first line in your CSV file must be a header record that contains the field names.
Specify one IP address per line.
For example:
ip 99.104.125.48 101.200.81.187 103.19.89.118
- Open Console.
- Go toManage > System > Custom Feeds.
- ClickIP Reputation Lists, and either clickAddorImport CSV.Your list of banned IP addresses is immediately enforced when your data is imported. A default runtime defense rule,Default - detect suspicious runtime behavior, logs an alert when a container tries to connect to a banned IP address.
- Review the default ruleGo toDefend > Runtime > {Container Policy | Host Policy}, then click manage for theDefault - detect suspicious runtime behaviorrule. You should see thatPrisma Cloud Advanced Threat Protectionis set toOn.
Supplementing the malware data feed
You can supplement the Prisma Cloud Intelligence Stream with your own custom malware data.
Update your custom list of malware signatures from the Console UI.
You can specify one entry at a time, or do a bulk upload from a CSV file.
The maximum file size is 20MB.
Malware scanning and detection is supported for Linux container images only.
Windows containers are not supported.
The first line in your CSV file must be a header record that contains the field names.
For malware data, specify the MD5, followed by the malware name.
Specify one entry per line.
For example:
md5,name 194836fbe0f121a25b145e55e80cef22,evil-malware 0aeb0cac186a81a6ac45776d6b56dd70,evil-binary 33cc273ae3aa8bce6a22c92e7d11f63a,bigevil
- Open Console.
- Go toManage > System > Custom Feeds.
- ClickUpload Malware Data, and either clickAddorImport CSV.Your custom malware data is used in all subsequent image scans. It is also used immediately by the runtime defense file system sensor, which assesses all writes to the host and container file system.
- Review the default rule.A default runtime defense rule,Default - detect suspicious runtime behavior, logs an alert when malware is detected using signatures from Prisma Cloud’s data set or your custom data set.To review the default rule, go toDefend > Runtime > {Container Policy | Host Policy}, then click manage for theDefault - detect suspicious runtime behaviorrule. You should see thatPrisma Cloud Advanced Threat Protectionis set toOn.
Globally whitelisting CVEs
Some organizations have have very sophisticated CI pipelines that encompass many teams and products.
When a security team concludes that a CVE doesn’t impact your organization, they want to dismiss it globally without having to manage individual rules.
Managing exceptions on a per rule basis requires a lot of manual effort.
The CVE Allow List lets you globally whitelist a CVE system-wide.
Any entry in the CVE Allow List affects all flows in the product, including twistcli, the Jenkins plugin, registry scanning, deployment blocking, Vulnerability Explorer, and so on.
Adding a CVE to this list effectively filters it out from the data in the Prisma Cloud Intelligence Stream before it’s used by the scanner.
The CVE Allow List takes precedence over any rule that’s been created under
Defend > Vulnerabilities
menu.
It is a feature designed to complement rules.
Rules also let you whitelist a CVE, but with more granular control.- Open Console.
- Go toManage > System > Custom Feeds.
- ClickCVE Allow List, and either clickAddorImport CSV.
Test Prisma Cloud’s malware detection capabilities
Safely simulate malware in your environment to test Prisma Cloud’s malware detection capabilities.
Configure a custom malware feed
Set up a custom feed by uploading the provided CSV file to Prisma Cloud Console.
This file specifies the MD5 signature for a file that will be considered malware for the purposes of this demo.
- Download malware.csv.
- In Console, go toManage > System > Custom Feeds > Malware Signatures.
- ClickImport CSV, and upload malware.csv.
Detect malware at runtime
Test how Prisma Cloud detects malware being downloaded into a container at runtime.
Prerequisites:
The default runtime rule, Default - alert on suspicious runtime behavior
under Defend > Runtime > Container Policy
is in place.
If you have deleted or changed the default rule, create a new one.- Go toDefend > Runtime > Container Policy, and clickAdd rule.
- Enter a name for the rule.
- In theGeneraltab, verifyPrisma Cloud Advanced Threat ProtectionisOn.
- In each of theProcess,Networking,File System, andSystem Callstabs, setEffecttoAlert.
- Run a container and download malware into it.$ docker run -ti alpine sh / # wget https://cdn.twistlock.com/docs/attachments/evilLook at resulting audit. Open Console and browse toMonitor > Events > Container Audits. You will see a file system audit that says malware was detected.
