[KB8943] Enable and configure HTTPS traffic caching in ESET Bridge with ESET PROTECT

Issue

  • Enable and configure HTTPS traffic caching in ESET Bridge while using ESET PROTECT

Solution

  1. Prerequisites
  2. Prepare an ESET Bridge certificate for HTTPS traffic caching
  3. Add the public part of the Certificate Authority to ESET applications via policy in ESET PROTECT
  4. Enable and configure HTTPS traffic caching in ESET Bridge via policy in ESET PROTECT

I. Prerequisites

  • ESET subscription with ESET PROTECT enabled and configured
  • ESET Bridge installed
  • Public part of the Certificate Authority
  • Supported versions of ESET applications installed on endpoint devices. HTTPS traffic caching for module updates and the repository is available only for the ESET applications listed below:
    • ESET Endpoint Antivirus/Security for Windows version 10 or later
    • ESET Endpoint Antivirus for Linux version 12.2 or later

II. Prepare an ESET Bridge certificate for HTTPS traffic caching

Use trusted certificates

It is recommended to use certificates issued by a trusted (official) Certificate Authority. Self-signed certificates should only be used for testing or non-production environments.

  1. The issued certificate must contain the following parameters:

    alt_names required

    The alt_names defined in the example below are required for the HTTPS traffic caching to work properly.

    [ req ]
    distinguished_name = dn
    req_extensions = v3_req
    prompt = no
    [ dn ]
    CN = ESET Bridge at *.eset.com
    [ v3_req ]
    keyUsage = critical,digitalSignature,keyEncipherment,keyAgreement
    subjectAltName = @alt_names
    [ alt_names ]
    DNS.1 = *.eset.com
    DNS.2 = *.eset.net
    DNS.3 = *.eset.systems
    DNS.4 = *.eset.eu
    DNS.5 = *.update.eset.com
    DNS.6 = *.cn.eset.com
    DNS.7 = *.edtd.eset.com
    DNS.8 = *.edtd.eset.systems
  2. Ensure that the issued certificate is stored in a .pfx container.


III. Add the public part of the Certificate Authority to ESET applications via policy in ESET PROTECT

ESET security applications use the Certification Authority to validate the peer certificate from the ESET Bridge policy.

Certificate Authority format

Ensure the public part of the Certificate Authority is available in .der format.

  1. Open the ESET PROTECT Web Console.

  2. Create a policy in ESET PROTECT or ESET PROTECT On-Prem or edit an existing one.

  3. In the Settings section, select ESET Endpoint for Windows or ESET Endpoint for Linux from the drop-down menu, click Connectivity, and click Edit next to Certificate Authorities.

  4. Click Add, click the file upload icon, select the .der file, and click SaveSave.


IV. Enable and configure HTTPS traffic caching in ESET Bridge via policy in ESET PROTECT

Enable HTTPS traffic caching and add a certificate to ESET Bridge.

  1. Open the ESET PROTECT Web Console.

  2. Create a policy in ESET PROTECT or ESET PROTECT On-Prem or edit an existing one.

  3. In the Settings section, select ESET Bridge from the drop-down menu, expand Cache, enable the toggle next to Cache HTTPS traffic, and click Change certificate next to HTTPS certificate.

  4. Click the file upload icon, select the .pfx file created in section II, and click SaveSave. If the certificate has a password, type the password into the Certificate password field. You can configure additional parameters in the ESET Bridge policy based on your environment.
