[Discovery Application Installation](https://support.block64.com/getting-started?hsLang=en#discovery-application-installation) # Block 64 Discovery Application: Technical pre-work ### Thank you for choosing Block 64’s rapid discovery technology to assist with your project! ### What is the Block 64 Discovery Application? Block 64’s Discovery Application gathers data about your environment to assist you in uncovering risk, opportunities to optimize, and chances to reduce unnecessary expenditures. ### The Data We Gather - **Network:** By scanning your internal subnets, we can detect all devices on the network and store their IP addresses. - **Hardware:**  Manufacturer and model information is recorded, as well as hardware-specific details like CPU and RAM. - **Software:** From general installed software records to database instances, we collect as much as we can without accessing personal data. - **Active Directory:** By pulling user and device data from Active Directory, we can gain useful analytical insights as well as have a reference for discovery progress. - **Virtual Infrastructure:** Collecting virtual management, host, and guest relationships is relevant to cloud readiness and server optimization activities. - **Usage and Performance Data:** Activity metering and resource utilization are valuable in assessing your cloud readiness and uncovering optimization opportunities. Our application is designed to be a simple and quick method of gathering discovery data, in scenarios where a simple snapshot is required or virtual architecture is not available to deploy our flagship virtual appliance. We have compiled a [Security FAQ](https://support.block64.com/faqs?hsLang=en#security) that is available on our website. ### Who will have access to my data? During the course of this engagement, and in order to prepare your deliverable(s), our analysis and support team at Block 64 and/or at the partner you are collaborating with will have the ability to view the data that has been gathered, which will be destroyed after 90 days after the last upload date. Our [Privacy Policy](https://block64.com/index.php/privacy-policy/) is available on our website.  ### How much of my time will this take? Truly, very little. The setup of the application takes 10 minutes or less. Once the proper network scope and service accounts are input, the rest is handled by the tool – just leave it running, and let it do its thing. If you need a hand, just contact us at our [help center](https://support.block64.com?hsLang=en). We’ve worked hard to make this easy! ### Operating System and Hardware Requirements - **Minimum** - Windows 7 64-bit SP1 or Windows Server 2008 R2 SP1 (or newer) - - CPU with at least 4 cores - **8 GB of *available* RAM** > ***“Available” RAM** refers to the memory that is free and usable at the time of installation, not the total physical memory installed.* > *If the system has 8 GB installed but part of it is already in use, the installation will fail and display an error indicating that the minimum RAM requirement is not met.* > *We recommend having at least 8 GB free (not just installed) to ensure a successful installation and stable performance.* If possible, we recommend installing Block 64 Discovery Application on a ***non-mission critical endpoint*** *for example, **do not install on a** **Domain Controller, SQL Server, etc.*** to avoid an unlikely scenario of interruptions or slower server response times due to increased workload. > **Please Note:** > 📌 The Block 64 Discovery Application cannot inventory the endpoint on which it is installed. If it is necessary to inventory this specific machine, the task can be accomplished using the [Block 64 Discovery Agent](https://support.block64.com/block-64-discovery-agent?hsLang=en). > > ⚠️ Outbound internet connectivity is required to authenticate the application with our cloud services. Ensure that the machine is able to connect to **combine.block64.com**. ### Downloading the Application and Activation Codes You will want to ensure that **discovery@block64.com** has been added to your whitelist or add the block64.com domain in its entirety as the download link and activation codes will be sent via e-mail to your inbox. ### You’ll want to have on hand: - **Network:** All internal networks in scope; CIDR notation or single IP addresses by line or .txt file - **Active Directory:** A domain controller per domain in scope; IP address or FQDN formats are accepted - **Windows Inventory:** A domain admin or a [service account](https://support.block64.com/creating-and-using-a-limited-service-account?hsLang=en) that has the following 3 levels of access will accomplish inventory: - Access to C$ *(Example: \\\\10.0.0.50\\ADMIN$\\... or \\\\192.168.2.5\\ADMIN$\\...)* - The ability to run NET RPC / Remote Registry *(Collection of Software/Hardware data)* - Remote WMI *(Read-Only Polling of CPU, RAM Usage & Disk IOPS)* **Alternatively WinRM can perform the full inventory independently:** - - WinRM *(Collection of Hardware & Software data)* - **Virtual Infrastructure:** Read-only administrator credentials for each vCenter Server in scope. - **Linux Inventory:** A local or domain credential with access to files in /proc/. Superuser rights are preferred for accurate data collection but are not required. - **Microsoft 365 & Azure API data:** - **Microsoft 365** - Your [global administrator account](https://support.block64.com/required-permissions-for-the-m365-global-administrator?hsLang=en), for authentication of our application, to gather read-only Office 365 such as your Secure Score, Usage and Activation data. - **Azure** - your Azure administration account, to gather Azure Advisor and Virtual Machine data. - **Cloud-hosted Endpoint Inventory:** A local administrative or service account for each endpoint that has access to the protocols required for full inventory (WMI, SMB, RPC). ### The Network Ports We Leverage A question we often get leading up to deployment or during troubleshooting is: *what ports will your inventory and other processes be leveraging on my network?* We have a complete list below – but some good news is that these ports are very rarely – if ever – blocked. Here is the complete list of ports we presently leverage for inventory purposes: **Windows Inventory\*:** - TCP 135, 1025-5000 and 49152-65535 (WMI) - TCP 445 (SMB – RPC) - TCP 5985, 5986 (WinRM) - TCP 1025 (Alternate Netbios) - TCP port 465 (SSL-Encrypted Email) - TCP 139 (NetBIOS) - UDP 137 (NetBIOS) **Active Directory Data:** - TCP 389 (LDAP) - TCP 636 (LDAPS) **External Data Feeds:** - HTTP 80 (External Data Feeds) - HTTPS/SSL 443 (External Data Feeds + Updates/Patches + External Data/Debug Transfer) **Linux Inventory:** - TCP 22 (SSH) (OSX + POSIX-Compliant Inventory + CLI access) We have developed comprehensive [instructions](https://support.block64.com/how-to-open-up-ports-on-windows-firewall-via-gpo?hsLang=en) to guide you through the process of creating and applying a Group Policy Object (GPO) that facilitates inventory management within a Windows environment.  Additionally, we have compiled an extensive [whitelisting guide](https://support.block64.com/whitelisting-block-64-in-your-endpoint-security-or-threat-management-tools?hsLang=en) specifically tailored for third-party security software.  > We highly recommend setting up the aforementioned [GPO](https://support.block64.com/how-to-open-up-ports-on-windows-firewall-via-gpo?hsLang=en) for endpoints to allow inbound connectivity exclusively from the Block 64 host machine. - [Getting Started](https://support.block64.com/getting-started?hsLang=en#main-content) - [Free Trial Onboarding](https://support.block64.com/getting-started?hsLang=en#free-trial-onboarding) - [Start Your Subscription](https://support.block64.com/getting-started?hsLang=en#start-your-subscription) - [Discovery Application Installation](https://support.block64.com/getting-started?hsLang=en#discovery-application-installation) - [Discovery Appliance Setup](https://support.block64.com/getting-started?hsLang=en#discovery-appliance-setup) - [Discovery Agent Deployment](https://support.block64.com/getting-started?hsLang=en#discovery-agent-deployment) - [Insights Reports](https://support.block64.com/insights-reports?hsLang=en#main-content) - [IT Asset Management](https://support.block64.com/insights-reports?hsLang=en#it-asset-management) - [Security](https://support.block64.com/insights-reports?hsLang=en#security) - [Cloud & Infrastructure](https://support.block64.com/insights-reports?hsLang=en#cloud-infrastructure) - [Legacy Combine User Guide](https://support.block64.com/insights-reports?hsLang=en#legacy-combine-user-guide) - [Troubleshooting](https://support.block64.com/troubleshooting?hsLang=en#main-content) - [Discovery: Insights Portal](https://support.block64.com/troubleshooting?hsLang=en#discovery-insights-portal) - [Insights Calculations](https://support.block64.com/troubleshooting?hsLang=en#insights-calculations) - [Discovery: Block 64 Windows Application](https://support.block64.com/troubleshooting?hsLang=en#discovery-block-64-windows-application) - [Discovery: BlockBox Appliance](https://support.block64.com/troubleshooting?hsLang=en#discovery-blockbox-appliance) - [Block 64 Discovery Agent](https://support.block64.com/troubleshooting?hsLang=en#block-64-discovery-agent) - [Documentation](https://support.block64.com/documentation?hsLang=en#main-content) - [Insights: Integrations](https://support.block64.com/documentation?hsLang=en#insights-integrations) - [Privacy and Security](https://support.block64.com/documentation?hsLang=en#privacy-and-security) - [Block 64 API](https://support.block64.com/documentation?hsLang=en#block-64-api) - [Discovery: General Knowledge](https://support.block64.com/documentation?hsLang=en#discovery-general-knowledge) - [FAQs](https://support.block64.com/faqs?hsLang=en#main-content) - [Security](https://support.block64.com/faqs?hsLang=en#security) - [Block 64 Discovery](https://support.block64.com/faqs?hsLang=en#block-64-discovery) - [New Features & Updates](https://support.block64.com/new-features-updates?hsLang=en#main-content) - [New Features & Updates](https://support.block64.com/new-features-updates?hsLang=en#new-features-updates) - [Combine](https://support.block64.com/new-features-updates?hsLang=en#combine) - [Block 64 Discovery](https://support.block64.com/new-features-updates?hsLang=en#block-64-discovery) - [Remote Discovery Agent](https://support.block64.com/new-features-updates?hsLang=en#remote-discovery-agent) - [Combine API](https://support.block64.com/new-features-updates?hsLang=en#combine-api) - [BlockBox Virtual Appliance](https://support.block64.com/new-features-updates?hsLang=en#blockbox-virtual-appliance) [![Logomark - dark](https://support.block64.com/hs-fs/hubfs/Logomark%20-%20dark.png?width=60&height=96&name=Logomark%20-%20dark.png "Logomark - dark")](http://block64.com) 300 Geary Ave, Toronto, ON M6H 2C5, Canada +1 800-875-5260 [www.block64.com](https://www.block64.com/)
