Hardening TheHive4 and Cortex for public deployment

Posted on By McHughSecurity 1 Comment on Hardening TheHive4 and Cortex for public deployment

Deploying an incident response platform on the open internet is not always a good idea. For whatever reason you choose to do so, there are some things you need to do before going live with TheHive and Cortex.

In this post, I talk about hardening TheHive and Cortex for an Internet-accessible deployment. This includes the application of TLS v1.2+ and the configuration of multi-factor authentication. Cortex can be further hardened through IP whitelisting, and even walled gardens implemented through Cloudflare.

[Part 4] Building a Threat Integration and Testing Lab – MISP Threat Intelligence Sharing Platform

Posted on By McHughSecurity No Comments on [Part 4] Building a Threat Integration and Testing Lab – MISP Threat Intelligence Sharing Platform

  4. [Part 4] Building a Threat Integration and Testing Lab – MISP Threat Intelligence Sharing Platform

MISP is a threat intelligence platform for sharing, storing and correlating Indicators of Compromise of targeted attacks, threat intelligence, financial fraud information, vulnerability information or even counter-terrorism information.

Within a well structured SIEM environment, a Threat Intelligence Platform may allow an organisation to generate new intelligence relevant to the organisation, and it may allow for the ingestion of external intelligence sources.

[Part 3] Building a Threat Integration and Testing Lab – Splunk Enterprise

As a bake off for the Threat Lab and Incident Response capabilities, we will also be installing Splunk Enterprise. This will be in the 30 day trial mode, so it would be advisable to seek advice from your Splunk sales representative prior to using this installation in a production environment.

You can potentially use a Cloud-hosted instance of Elastic Cloud Enterprise, however since I am trying to avoid putting this environment on the Internet, I will be building ECE in my home lab environment.

[Part 1] Building a Threat Integration and Testing Lab

  4. [Part 4] Building a Threat Integration and Testing Lab – MISP Threat Intelligence Sharing Platform

For this article and subsequent articles, I will be talking through the installation, configuration, and integration components in building an integrated threat and incident response lab. The primary purpose of this lab is to be able to replay malicious attack data into a SIEM environment (Splunk and Elastic will be used) and then generate appropriate alerts and actions within those SIEMs for an analyst to action. In addition, both SIEMS will be integrating MISP as a Threat Intelligence Platform to consume enriched intelligence and store and process newly generated intelligence from the lab.

  4. TheHive 4.1.0 Deployment and Integration with MISP

Every few months, StrangeBee puts out an update to TheHive (Security Incident Response Platform). This month they have added Elasticsearch as an index engine to alleviate issues with using Cassandra, and they have integrated support for MISP galaxies as well!

Now Incident Responders using TheHive can export IOCs and Galaxy assignment directly from TheHive to MISP.

I have been an off and on user of TheHive for nearly a year now, and it is encouraging to see the development and release of TheHive4 (even if in pre-release). In this post I will walk through the deployment, configuration and migration of TheHive to TheHive4, and what improvements have been implemented into this release.

Building a Cuckoo Sandbox

Posted on By Adam McHugh 1 Comment on Building a Cuckoo Sandbox

Sometimes there is a need to analyse files in a live environment where their composition and provenance may not be entirely certain. For the most part we can try to reply on virus detection and heuristics to detect potentially malicious files, but what about those files which have not yet been identified, or have been specifically crafted for your organisation as a targeted attack?

Note: I have updated this article to reflect the current installation requirements for Cuckoo on Ubuntu 18.04 (as at 22nd Feb 2021).
