Enable

Packet captures after applying SSL decryption rules

to apply your already-configured SSL decryption policies on the PCAP files.

Only traffic that matches with the inline SSL decryption policy will be decrypted.

If you select this option, the PCAP files will use the same decryption rules that you have specified in your deployment. If you deselect this option, no decryption will be performed on the PCAP files, regardless of the decryption rules you have configured.
For
Traffic Replication encryption certificate
, select any certificate you have added in the
Objects
Certificate Management
Certificates
Custom Certificates
Generate
page or
Import
the certificate to use for SSL decryption.
The certificate consists of a public and private key. Upload the public key in
Prisma Access
; you keep the private key and use it for decryption when you download the zipped PCAP files from the storage bucket. In this way, you guarantee that only your organization can access the storage bucket where the PCAP files are stored.
Configure the GCP service account you created in Step 1.
Traffic replication is supported only for GCP accounts. This service account is used to share read-only access to the storage buckets where the PCAP files are stored in the locations where you have enabled traffic replication. You create these service accounts in your GCP account using normal GCP service account creation procedures. It is your responsibility to control what users have access to these service accounts. Any users who have both access to the PCAP files and access to the private key would have access to the PCAP files.
In the
Access Management
area,
Add Account
details to share read-only access to the storage buckets where the PCAP files are stored.
Enter the following parameters:
Give the account a unique
Account Name
.
Specify
GCP
as the
Type
for the account.
Specify the
Account
information from the GCP service account you created.
Enter a
Member/User
name for the GCP service account.
Configure traffic replication for one or more Mobile User locations.
In the
Traffic Replication
area, select the locations where you want to enable traffic replication, then select
Mobile Users
.
You select the
Compute Location

Download the PCAP files.
Use the
Cloud Storage Links
to access the PCAP files in your GCP storage buckets.
These storage buckets support the same regular operations, commands, and queries as any other GCP storage buckets.
You can download PCAP data for up to 72 hours. After 72 hours, the files are permanently deleted.
Files are encrypted using your public key.
Maximum file size is 200 MB or 5 minutes of packet capture, whichever is smaller.
List the files in your service by entering enter
gsutil ls gs://
<storage_bucket_link>
/
, where
<storage_bucket_link>
is the storage link in your GCP service account where the files are stored.
Download the files from your service account by entering the enter
gsutil cp gs://
<storage_bucket_link>
/
<file_name>
<destination folder>
, where:
<storage_bucket_link>
is the storage link in your GCP service account where the files are stored.
<file_name>
is the name of the PCAP file.
<destination folder>
is the folder where you want the PCAP file to be downloaded.
Unzip the downloaded files.
Decrypt the downloaded files.
