Here is a table of license violation conditions by Splunk Enterprise license type: Violations due to broken connections between license master and slaves A license slave communicates their license volume usage to the license master every minute. Which license type allows 500MB/day of indexing, but disables alerts, authentication, cluster, distributed search, summarization, and forwarding to non-Splunk servers? Forwarder license c. Enterprise license d. Enterprise trial license 3. What can be used when setting the host field option on a network input? Splunk indexes and makes searchable data from any app, server or network device in real time including logs, config files, messages, alerts, scripts and metrics. When you download Splunk for the first time, you are asked to register. Your registration authorizes you to receive an Enterprise trial license, which allows a maximum indexing volume of 500 MB/day.

This guide is for help with the overall tasks needed to install Splunk in a Distributed Deployment suitable for the Enterprise, e.g. an Enterprise Security Use Case

SummaryThe following guide has been assembled to provide a checklist for and considerations for the Installation and Configuration of Enterprise Security.This guide is NOT an authoritative or complete guide, see docs.splunk.com for latest and authoritative reference, here at latest Enterprise Security manual [1]
Splunk provides detailed documentation on each subject and we strongly encourage all Splunk Administrators to read the documentation relevant to the topic at hand at docs.splunk.com as the final reference and latest information. When you get stuck, Splunk has a large free support infrastructure that can help:

Splunk Enterprise LicenseBefore Starting Here are the KEY references you will need:Review these links for the latest Splunk App for Enterprise Security information:
ES manual http://docs.splunk.com/Documentation/ES/latest/Install/Overview
Splunk Education for ES Training - CIRT / CSOC etc. http://www.splunk.com/view/SP-CAAAH9S
Before Installing Enterprise Security - Splunk Core:Develop a Splunk data collection topology with Splunk Professional Services and Support, you can get help with all of these items and more. Contact Splunk Professional Services.
Have a Splunk Core Deployment in place:Make sure hardware or virtual machines are sized for the deployment and install operating systems.
See the 'Hardware capacity planning for your Splunk deployment' in the Splunk documentation
Guidelines on the sizing needs of a deployment server [5]Platform and Hardware Requirements [6]
Install OS of choice, decide on the mount points for your warm, cold and frozen data.
Verify Network connectivity, ports [7]
Create a local Splunk account and a splunk domain user for system activities.
Ensure Splunk Admin has installed or downloaded the necessary software.
ES is typically setup in a distributed Splunk deployment which consists of different systems which are dedicated to running Splunk, configured in the following roles; 
Splunk Indexer(s)
Splunk Search Head for License Master, Deployment Server, and other Apps
Splunk Dedicated Forwarder on Windows OS for if Microsoft Data Sources
Splunk Dedicated Forwarder on Linux for Syslog, and appliance data sources
Splunk Search Head for only Enterprise Security App.

Planning to collect Enterprise Security Data SourcesReview Current log collection capabilities and goals
Understand the data sources that are required and recommended to make the most meaningful correlations for security content for your organization.

Consider Data Sources for perimeters like firewalls, core routers, etc.
Consider Data Sources for internal appliances like IDS, IPS, DNS, ActiveDirectory, LDAP
Consider Collecting windows logs, by deploying out the Splunk Universal Forwarder to Windows Servers
Consider other operating system logs, e.g. Linux, Solaris, and deploy a Splunk Universal Forwarder
Consider the destination of syslog traffic sources to a log management system.
Consider Data sources for Assets and Identities *** critical to using Splunk workflow
Assets and Identities http://docs.splunk.com/Documentation/ES/latest/User/Identitymanagement
Assets and Identities Lists and FeedsPlan and develop the Assets and Identities feeds with attention to identify the known/Expected devices and hostsThese are key files to make sure are filled out to the best of the ability of the system owner. 
This includes understanding your enterprise's assets and identities on the 'blue' team defenders side. With an authoritative source of valid assets (servers, workstations, phones, etc.) and valid identities (admins, guests, users) then an understanding of the enterprise's overall security posture can be established.
Assets (blue team systems) : Think about DMZ, crown jewels, ftp systems, vendor gateways, financial servers, HR serversIdentities (blue team access) : Think about privileged user groups, administrators, services accounts, vendor accounts, ftp accounts
assets.csv
You need at minimum the IP addresses of the systems you want to gather data from and enter these into this csv file.
Plan to have a script run from a cmdb or a network nMAP scan to collect this data regularly about the environment
Plan to survey server owners on the impact of data compromise of their systems. Safe4cam download. Establish criticality of assets by bunit.
Note: This default set of column headers must be in any asset file you use.ip,mac,nt_host,dns,owner,priority,lat,long,city,country,bunit,category,pci_domain,is_expected,should_timesync,should_update,requires_av

 identities.csv You need at minimum a list of known default, privileged, service and administrator accounts. All members of the security team, key data access users, e.g. privileged accounts. 
Use this CSV header line for identity information:identity,prefix,nick,first,last,suffix,email,phone,phone2,managedBy,priority,bunit,category,watchlist,startDate,endDate

IF YOU HAVE AD / LDAP ACCESS here is a sample search |ldapsearch domain= search='(&(objectclass=user)(!(objectClass=computer)))'|makemv userAccountControl|search userAccountControl='NORMAL_ACCOUNT' 

If you are collecting Windows Active Directory information then a search like this will help validate you have added them to assets.
index=msad sourcetype=ActiveDirectory | stats count by host | rename host as asset | sort +count | join [| `assets`]
Interdependencies with other teams, systemsNeed a firewall / proxy whitelist for *.splunk.com with web proxy for software notifications and updates
Need a firewall / proxy Whitelist rule to allow access to download the desired threatlists and APIs to enrich data, e.g. blocklists, arin.net, etc.
Create firewall routes for assets that will forward data to the Heavy Forwarder, or Indexers
See Splunk Ports Network connectivity - What are the Splunk ports that I need to open [12]
Verify DNS is configured on the network
Verify NTP is configured correctly with the right time on Splunk devices
Collect SMTP server and credentials
Collect LDAP server and credentials
Create SSL certificates for each Splunk device
Create a VIP and DNS entry for the search head tier.
Create a VIP and DNS entry for the forwarding tirer, e.g. syslog, heavy forwarders
Create a VIP and DNS entry for clustermater, deploymentserver
Service Accounts for a Splunk System User
Splunk Administrator Accounts, needs access to Splunk Servers (SSH or RDP)
All Accounts need access to Splunk configurations and indexes (read/write access to filesystems)
If Sign Sign on is desired then access to; LDAP, AD, Apache HTTP (web proxy, SSO)
If Database connections are desired, a database service account for Splunk needs to be created.
Create a domain windows service account for splunk userCreate a local user on linux for splunkCreate splunk groups in the domain

Identify a SME for each technology add-on you want to deploy and feed into ES.
Develop a TA for your data sources and install on the Indexer and Enterprise Security Search Head. [17]
When developing a TA for ES consider these necessary field extractions: [18]

Review the standard logging for other device types like these:
Cisco Devices -Know which components you have installed, FWSM, ASA, PIX, ACS [19]
When gathering log types, consider other teams use cases. -E.g. collecting UCS logs may or may not be relevant to some security teams but is interesting to a NOC.
Installing Splunk Enterprise Security ApplicationIf you have a support contract for Enterprise Security, then you can download the SPL file from SplunkBase.Contact your Splunk Sales team if you need access.
Before getting started take a look at known issueshttp://docs.splunk.com/Documentation/ES/latest/RN/KnownIssues
