Introduction Every automated task in Cortex XSOAR relies on executing commands from integrations or automations either in a playbook or directly in the incident war room or playground. But what if you wanted to incorporate a command or automation from Cortex XSOAR into your own custom scripts? For that you can use the API. In … Continue reading Cortex XSOAR Tips & Tricks – Execute Commands Using The API
Introduction When developing automations in Cortex XSOAR, you can use the Script Helper in the built-in Cortex XSOAR IDE to view all the scripts and commands available for automating tasks. When there is no script or command available for the specific task you want to automate, you can use the Cortex XSOAR API to automate … Continue reading Cortex XSOAR Tips & Tricks – Using The API In Automations
Introduction The war room in Cortex XSOAR incidents allows a SOC analyst to do additional investigations by using any command available as an automation or integration command. It also contains the output of all tasks used in playbooks (if not in Quiet mode). In this blogpost we will show you how to format output of … Continue reading Cortex XSOAR Tips & Tricks – Tagging War Room Entries
Introduction When developing the automated SOC workflows for the NVISO Managed SOC and the additional NITRO services on Cortex XSOAR, we have started to make use of automations to do complex tasks instead of playbooks. Automations have much better performances and, if your team has a decent level of Python skills, developing complex tasks in … Continue reading Cortex XSOAR Tips & Tricks – Execute Command Function
Introduction With our Managed Detect and Respond (MDR) service, NVISO provides a managed Security Operations Center (SOC) for a large variety of clients across different industries. Since the beginning of this service, we had an “automate first” principle where we tried to automate as much of the repetitive tasks of the SOC analysts as possible, … Continue reading Cortex XSOAR Tips & Tricks
Introduction With our Managed Detect and Respond (MDR) service at NVISO we provide a managed Security Operations Center (SOC) for a large variety of clients across different industries. In our SOC, we rely heavily on automations performed by our SOAR platform Palo Alto Cortex XSOAR to minimize the manual tasks that need to be done … Continue reading Automated spam detection in Palo Alto Cortex XSOAR
In a previous blogpost, we discussed the OS hardening baselines for Windows Server 2016 written in PowerShell DSC, which we made publicly available on the NVISO GitHub page. Using this, you can define your own hardening baseline to use within your own environment. Once a baseline is defined, we want to apply it to the … Continue reading Windows Hardening in the cloud with Azure Automation
Operating system hardening is the process of improving the security of a default OS installation to minimize the attack surface that can be exploited by an attacker. But doing this manually on each system that is deployed on-premise or in the cloud is a cumbersome task. It can lead to inconsistent security configurations because of … Continue reading Windows Server Hardening with PowerShell DSC
In this third blog post in a series about Azure Security Logging, we will focus on collecting security logs from Windows and Linux virtual machines. In part 1 we discussed how to define a security logging strategy in Azure. Part 2 went into detail about logging in some of the key Azure services. In this … Continue reading Azure Security Logging – part 3: security-logging capabilities of Azure virtual machines
In this second blog post in a series about Azure Security Logging, we will focus on some of the key services that are used in most Azure deployments. We go into detail how logging can be enabled, what logging options are available and what relevant data is generated. Log sources in Azure At the moment … Continue reading Azure Security Logging – part 2: security-logging capabilities of Azure resources
