To get this performance, you will need to be using fast drives in an optimal RAID configuration served by an efficient controller (either internal, DAS, or SAN). The DS can be collocated with any other full Splunk instance; however, there are also some reasons why it might need to be stand-alone. Containing all of these knowledge-items helps with manageability of the data across an enterprise deployment. This page contains links to assorted topics on Splunk best practices. Beware not to go nullQueue-happy and drop too much. OU=splunkgroups) in AD, then create your access groups under this, e.g. Scripted deployment for Linux UFs. Document Structure SVAs are broken into three major content areas: 1. Explicitly configure Splunk to read time stamp information from incoming events. NOTE: This can be any permissible port, 9998 is just an example. All Splunk systems have a default username of admin and password of changeme and this includes Forwarders (Universal Forwarders and Full Forwarders). Port commonly used to send events from a Splunk forwarder to a Splunk listener (indexer or another forwarder) using encryption. Adjust ulimit. Architecture and Design To configure active directory monitoring on a specific domain controller, open, Create a new Active Directory monitoring stanza and set the. Some are written by Splunk employees, and some are contributed by our users. Data is often not considered security relevant at first, until there is a security incident related to the data. I'm wondering how other admins balance their clients vs multiple (if necessary) deployment servers. Port commonly used to send events from a Splunk forwarder to a Splunk listener (indexer or another forwarder). Carefully plan Splunk Distributed Architecture to ensure the most accurate and efficient processing. Consider moving your Splunk database (SPLUNKDB) to its own volume to ensure clean separation of the binary/configuration structure and the data. They reference DLL files that contain the pertinent information instead of placing it in the actual log. This will include implementing a backup plan. Manage your ES Identities to always get the most value out of your deployment. Our certified Splunk Architects and Splunk Consultants manage successful Splunk deployments, environment upgrades and scaling, dashboard, search, and report creation, and Splunk Health Checks. Points to Remember. Deployment Server. Both the slides and a recording are available. If you created a new base_ou (e.g. I found an error If there are more than this, consider implementing a process (i.e. NOTE: This can be any permissible port, 9887 is just an example. (On Windows Server 2003 and Server 2003 R2, the event code is 566). Before attempting any performance remedies, first try and determine what may be adversely affecting your deployment’s performance. In fact, doing so can significantly increase the memory usage footprint on your domain controllers and your Splunk indexing volume. Managing Splunk instances on these remote systems always has problems and leads to issues such as: Forwarders that have not had Splunk configured properly or locked down (e.g. By the end of this course you will gain enough knowledge to complete “Splunk power user certification” How to estimate a Splunk architecture servers. The memory allocated to the UDP input buffer is distribution-specific. Not all searches qualify for acceleration. This article explains how splunk data models and datasets work, how to define a data model using the Splunk editor, and important best practices for efficient data model design. Splunk has put together this Best Practices in the course of developing and using the Splunk App for Windows Infrastructure. lookups, extractions), and dashboards. Solid state drives do not provide much performance in dense searches (high event counts). Splunk hardware planning: Determine what components you need. Enter your email address, and someone from the documentation team will respond to you: Please provide your comments here. RPM repo, Puppet, Satellite Server) to manage packages and configurations to forwarders and other related systems. Module 6 - Forwarder and Deployment Best Practices. Splunk can work with either AMD or Intel architecture on x86 systems, but is typically run on Intel hardware. These files are nothing like normal log files and therefore present some challenges to any attempt to reconstitute them back into usable logs (Note: These issues have nothing to do with Splunk): They reference GUID/SIDs in lieu of system/user names. Memory is somewhat varied depending on what component you are talking about. Once you update configurations, you must restart the universal forwarders on each domain controller for the new changes to take effect. Additionally, if leveraging existing groups there could be many other users in that group that you don’t want to have access to Splunk. Finally, you should understand your data sources and either their load/volume or the complexity required to collect data from them. Here are your best practices for those of you who are either considering implementing Splunk or who have already implemented Splunk and are having issues getting it to do what you need it to. Adjust the ulimit if necessary such as: Apply changes to limits.conf by logging out and logging in again. All other brand names, product names, or trademarks belong to their respective owners. Be sure you know what you are changing and have tracked changes and the results appropriately to ensure it has the desired effect. Generally speaking indexers do particularly well with 16+ GB of memory, meanwhile other components might require less. during an upgrade), it can pick up where it left off reading the files on disk. cron) to move the previous day’s (or week perhaps) syslog directory out of the monitored directory-structure to an archive location. Enterprise Security has many useful dashboards for various protocols. Divide this by 400 (average bytes/message) and you get 15625 which is the total amount of messages we could possibly receive if optimally configured with tcp given the parameters. Deployment Server: Best practices for scaling coltwanger. This procedure requires that you use Splunk universal forwarder version 6.1 or later. Test new inputs. these instructions to Forward data to third party systems, network and system performance implications, Add Indexers when volume reaches 200GB/day/Indexer, Add indexers when volume reaches 80GB/day/Indexer. This is granular Role Based Access Controls (RBAC). You should still install the Splunk_TA_microsoft_ad add-on into each domain controller. LOGO Splunk Server 9. In this file, modify the Security Event Log stanza. Generally speaking here are the standard ports, if they have not been altered: Splunk’s daemon port used for distributed search and deployment server. This system typically acts as the License Master. If you are processing 100GB/day of data volume for use with Enterprise Security, you will need approximately 340GB more space available across all of the indexers to allow for up to 1 year of data model retention and source retention. Splunk is a fantastic tool for individuals or organizations that are into Big data analysis. Keep an Eye on Free Disk Space. Other. Methodically plan storage needs for a new deployment, prior to implementation. © 2020 Splunk Inc. All rights reserved. There are a few things to keep in mind though, specifically that you probably want to pass the following Splunk start-time arguments: –accept-license, –answer-yes, –no-prompt. Avoid overwriting or hard-coding the source field in the data. Consider the implications of parsing data directly on your Indexers or using Intermediate Heavy Forwarders. Use the clientName directive in the deploymentclient.conf to ease whitelisting and blacklisting in your serverclass.conf. Since the EVT(X) files are a subset of the information they represent, a 99MB EVTX file converts to almost 500MB of indexed data. The syslog-ng developers have a blog post where they discuss possible volumes with the 2.0 OSE: This means they are processing 44000*150=6600000 bytes per second, Multiply 6600000*8 to get bandwidth: 52,800,000, So syslog-ng optimally configured (by its developer) can use about half of the 100/mbs Ethernet connection without dropping packets.

Below are the components of splunk Architecture: 1) Search Head --> Splunk search head is basically GUI for splunk where we can search,analyse and report 2) Forwader --> Splunk forwarder is a splunk components which works like an agent for splunk .It collects da,routers etc. Only deploy configuration and parsing apps, such as Technology Addons (TA’s). Much of this configuration must be done with the outputs.conf file. You should also install the Splunk Add-on for Windows (Splunk_TA_Windows) onto the host to get all other Windows data for the host into the Splunk App for Windows Infrastructure. Traditional syslog technologies (syslogd, syslog-ng, rsyslogd) are simple and featureless compared to Splunk, but this is their advantage. A useful resource on Data on-boarding is the 2014 Splunk .Conf talk. Dimitri McKay has held a list of positions in the security space through his 20+ years of working with Fortune 500 companies in and around security best practices, architecture and design. DRP/BCP. Inconsistent configurations leading to similar systems setting different metadata on the same type of logs. LOGO Splunk Enterprise vs Cloud 7. Read about Splunk components to better understand what exists. If you have understood the concepts explained above, you can easily relate to the Splunk architecture. You can script your deployment of Universal Forwards for Linux depending on what tools you have available at your disposal. The Splunk App for Windows Infrastructure does not need SID translation in the Security Event Log. Also note that newer versions of ES (starting with 3.0) no longer store summary data in TSIDX file on search head, please see Splunk’s deployment planning documentation for updates to these numbers as they can vary at times. Use Splunk AutoLB (Load Balancing) to distribute data to multiple indexers/forwarders. Syslog systems should be tested and tuned to perform as needed. Based on the feedback on the data, the IT team will be able to take the necessary steps to improve their overall efficiency. Splunk Architecture. There are TB of logs stored on the CIFS share. This white paper is a reference guide for configuring Splunk SmartStore with ECS and the recommended best practices. TA_AD and TA_DNS are merged with TA-Windows version 6.0.0. Therefore, I decided to write this […] Learn more (including how to update your settings) here ». Aplura’s PAVO Security apps has dashboards to cover major security domains. (sample script below to put in cron.daily or weekly). Introduction To Splunk Logging. Your hot volume should cover that, with a little bit of breathing room. Splunk’s reads the time stamp from incoming events, which it then associates to the event in the index and the underlying buckets. Ensure a single instance of Splunk does not monitor more than a few hundred active files. Modularize your programs for better reusability. See the “Storage Hardware” section in this document for many notes regarding hardware. Create a DNS host name specific to the DS (e.g. The Microsoft AD tool adsiedit.msc is great to browse an AD domain for valuable items necessary to setup AD auth on Splunk. syslog-ng) on the network to receive the syslog feeds and configure the application to write the data out to files. Splunk has put together this Best Practices in the course of developing and using the Splunk App for Windows Infrastructure. Enterprise Security’s search load can apply more memory pressure. Many of these items come up time and time again during engagements and consideration of these items will result in a more successful implementation. You can script your deployment of Universal Forwarders for Windows depending on what tools you have available at your disposal. Master Node. If your use case requires direct reads of the Windows EVT(X) binary files then consider the following information: EVT(X) files are the raw binary-format files that Windows uses to store its logs on the file-system. On a very busy server, this could happen frequently or in some cases continually. This tool will be a perfect fit where there is a lot of machine data should be analyzed. This is because Active Directory events already contain this information. Some of these are referenced when Splunk starts. There are various ways to test your storage to benchmark your current values, but the mostly commonly used method is via the venerable tool bonnie++ found in the repository of every major Linux distribution. Translation turns SIDs (the very long string that begins with S-1-5-21 and ends with a long jumble of numbers) into friendly account names. Consider the trade off of having less total hot storage that is faster versus more total hot storage that is slower in some uses cases. Closing this box indicates that you accept our Cookie Policy. This is not intended to replace a scoping discussion with a Splunk Sales Engineer, but rather to assist a customer in preparation for a professional services engagement. Splunk is a software that enables one to monitor, search, visualize and also to analyze machine-generated data (best example are application logs, data from websites, database logs for a start) to big-data using a web style interface. Continue to manage your ES Asset List to always get the most value out of your deployment. WMI is very clunky, and generally should not be used due to network and system performance implications. This can be very tricky and you need to be careful since you could destroy and disable your data. Unless you specifically need a baseline of your AD schema, consider turning it off. The resulting document, a Cisco Validated Design (or “CVD”), is a comprehensive implementation and best practices guide geared to IT Architects and Administrators. This should be considered the minimum. These lookups can be used in various ways but the most popular method is as watchlistsOS Configuration or Hardening. Too many files. There are many online guides (even on Splunk’s site) for how to run this tool; however, below is the gist: Ensure the target drive to be tested (e.g. Little impact will be seen at low volumes; however, at higher data volumes you will see performance improvement with RAID1+0 over RAID 5 or 6. Use a consistent naming scheme on the Splunk Search Heads, Indexers to ensure accuracy and reduce troubleshooting time. Splunk can work with either AMD or Intel architecture on x86 systems, but is typically run on Intel hardware. There are a few things to keep in mind though such as: Although it is much easier to have the Splunk MSI files in a UNC that you can mount/reach from any system, sometimes windows security policy prevents this from working. You must know the amount you expect to index/day. If you use a Splunk Enterprise deployment server, create server classes that deploy the add-ons with these updated configurations. NOTE: This can be any permissible port, 9997 is just an example. Best practices guide. Change the admin password on forwarders. Use RAID1+0 whenever possible for the Splunk datastore. Memory Spec. Recommended Splunk Enterprise sizing: 150GB/day per Indexer. When deploying Indexers, strongly consider indexer clustering. When you collect Active Directory data for the Splunk App for Windows Infrastructure, it is not necessary to enable the Active Directory monitoring input (admon) on every domain controller in your Exchange environment. When creating fields/eventtypes refer to the Splunk Common Information Model to ensure forward-compatibility with Splunk and Splunkbase built-ins. We also use these cookies to improve our products and services, support our marketing campaigns, and advertise to you on our website and other websites. Splunk recommends 800 IOPS (Input/Outputs Per Second) or better on your storage tier. For indexers, the current sweet spot for servers has been 12-16 core machines (I.e. Manage Identities. Splunk has multiple classes focusing on search and dashboarding. This will make it much easier to migrate later, if you choose to. Scale by adding more Indexers. Memory is somewhat varied depending on what component you are talking about. If the app is distributed via deployment server, the files and directory structure in the app will be replaced with those from the deployment server, which would include any log or pid files. For Symantec Endpoint Protection, you can put the SEP server in a configuration where it will write out temp files that a Splunk Universal Forwarder can read. Deploy and Use the Splunk App for Windows Infrastructure. In general this is not required and only complicates deployments. I did not like the topic organization When configuring AD, you can specify a list of one or more bindgroupDN for Splunk to look for groups in AD. If an event is relayed through multiple syslog servers (for example the local syslog on a Linux system sending events to a remote syslog server), there may be two time stamps at the start of the event. If you have a number of domain controllers, consider selecting one (or two to three for redundancy) and enabling the admon inputs only on those hosts. Avoid reading Windows raw EVT(X) files if at all possible. When developing an app, ensure that any log or pid files are not stored in the app’s directory. Before activating Splunk Windows Forwarders configure custom indexes, Information: Monitor files and directories. We strongly recommend using Splunk_TA_Windows. Free Demo Session Timings: Read more: Anatomy of a Splunk Data Model. This document covers the various best practices for Splunk on Pure Storage. This separate system will distribute any search request across all configured search-peers improve search performance. Consider backups for the $SPLUNK_HOME/etc on each standalone search head (non-pooled) and the cluster node to a remote drive on a frequent interval. Splunk should be run on 64 bit platforms. Use separate IP addresses whenever possible. Forward to a Splunk system whenever possible, but if there is a Use Case to send to an external system, following these instructions to Forward data to third party systems. Below are components of Splunk: Search head – provides GUI for searching Indexer – indexes machine data Forwarder – Forwards logs to Indexer Deployment server – Manages Splunk components in distributed environment Print the Splunk Cheatsheet (PDF) for users. CPU is somewhat varied depending on what component you are talking about. Splunk takes advantage of file system caching provided with most modern Linux distributions, so adding memory can provide a great benefit. To reduce the amount of memory that domain controllers use to perform SID translation, configure the Splunk Add-on for Windows (Splunk_TA_Windows) to disable SID translation. An indexer, when used in an ES deployment, can accommodate up to 100GB/day. There are a few things to keep in mind though, specifically that you want to pass the following msiexec arguments: AGREETOLICENSE, INSTALLDIR (since many sites want to install to some drive besides c ), Below is an example content that you can put in a script/package-management and it is based on having a Splunk deployment server in place. 1. Below is an example content that you can put in a script/puppet/rpm Many of these items come up time and time again during engagements and consideration of these items will result in a more successful implementation. If you just give the root dir of all of the groups then Splunk could return hundreds/thousands of Groups. If you must do this manually, read and understand the docs and how the bucket structure works, and you can take a look at this answers post on the subject. LOGO Splunk Architecture 8. If you need assistance implementing a Splunk Validated Architecture, contact Splunk Professional Services. Answering these three questions will suffice for the average deployment, but not all deployments. Many events while insignificant by themselves provide useful information when trended or otherwise analyzed. Manage Assets Lists. If Splunk requires a restart or is otherwise unavailable (i.e. You must be logged into splunk.com in order to post comments. Currently he’s a Principal Security Specialist for Splunk. This guide is specific to Splunk on Pure Storage including reference architecture, best practices and suggested guidelines for implementing Splunk at Enterprise Scale on Pure Storage products. Splunk installation, commissioning and architecture best practices. In our tests, many GUIDs and some DLL references didn’t convert in the event logs, leaving lots of useless events. Architecture type. Since the DS requires so many active TCP sessions (at least one for each connected client), choose a system that already has a limited number of open TCP sessions to other systems, such as a Search Head. In very specific use-cases, Heavy Forwarders can still provide value. This is not necessary, but there are advantages in high-volume environments. For very in depth logging on critical systems, consider using the Splunk addon for Microsoft sysmon in addition to Splunk_TA_Windows. Splunk Best Practices The recommendations in this document were compiled by Aplura's staff over their many years of Splunk administration and professional services engagements. Carefully and consistently use Splunk’s listening ports, which bind to specific back-end processes. Note: The Windows Time service is not a full-fledged NTP client and Microsoft neither guarantees nor supports the accuracy of the service. Please see other recommendations for managing these files. Be sure to understand what it is, and how it operates. When network devices send syslog messages, this data is frequently UDP (connectionless) and therefore vulnerable in-transit. The Splunk Reference Card PDF is also a great resource, and a laminated version can be purchased from the Splunk Schwag store. Systems generating events should have the proper time to ensure the events they create will be able to be correlated when analyzed. No Heavy Forwarders means you always know where your data is being parsed (the Indexer). Memory Spec. Splunk will benefit greatly from increased disk performance above the 800 IOPs minimum. To address the problem, limit the indexing of these event codes by blocking some of the events which contain them (the app uses the events for Group Policy monitoring but no other purpose.). This system is typically co-located with the Deployment server. You want to not use it in order to get an accurate reading from bonnie++ without competing for resources with it. The topic did not answer my question(s) Consider taking a Splunk EDU class. Ingest time is slow since many AD calls are necessary for GUID/SID queries. Proxy servers listening directly on … (sample script below to put in cron.daily or weekly), Backup the master node, the /$SPLUNK_HOME/etc/master-apps directory to a remote drive is recommended to quickly build a new master node. Many Windows event collection tools have various limitations such as the truncation of events at 512 or 1024 bytes. This hard-codes a download of the Splunk UF RPM at each invocation. In general, most deployments would benefit from having the following: Splunk hardware planning: Determine number of indexers. It is a best-suited tool for root cause analysis. Design principles and best practices Imagine a device that generates messages that are 250-450 bytes with most being over 350. A separate search head is shown here to support Splunk’s Enterprise Security (ES) application. He is an avid public speaker, author and proponent for security best practices, risk and compliance. Use GetWatchList. This includes the Splunk Classic architecture with Hot/Warm on Pure FlashArray, cold on Pure FlashArray over FC/iSCSI, or FlashBlade over NFS as well as Splunk SmartStore architecture with data on … Hard drive speed makes a difference. Integrate Active Directory (AD) for authentication. I already see a lot of Splunk deployments with a terrible app and server class structure, which makes it very difficult to manage the Splunk infrastructure. Will Splunk users wish to either search the target data by itself or search other data and omit this target data? Drop incoming data with the nullQueue. Splunk has informally documented that an increase in drive-speed will have a dramatic improvement on performance. (sample script below to put in cron.daily or weekly). Additionally, much of the deployment of Splunk requires an intimate understanding of its intended use and therefore it is recommended that the team who will be the major user of Splunk should also manage its deployment. Splunk hardware planning: Know what the size/scope of your deployment is. The best practices in the platform functional area support the availability, scalability, and maintainability of your Splunk deployment. Consider one Deployment Server instance for every 2000 polls per minute. With that in mind, 24GB+ of memory on Indexers running ES is recommended. Occasionally review your inputs and ensure your data is accurate, time stamps are good, and there are no mistakes such as incorrect or duplicated events. Using deployment server can help keep consistent configuration across Splunk systems, and make configuration changes much easier (no having to touch every system). Splunk works well with both 32 and 64 bit platforms; however, there is a considerable performance improvement for 64 bit and this should be selected (both for Hardware and Operating System) whenever possible. In accordance with, Watch out for chained syslog time stamps. Please select The recommendations in this document were compiled by Aplura‘s staff over their many years of Splunk administration and professional services engagements.

Prepend deployed configuration apps (not TA’s) with “DS-“. No, Please specify the reason For large deployments, a stand-alone system is important. Implement a central software management system (e.g. Scripted deployment for Windows UFs. Below are some best practices for tuning Active Directory monitoring operations for the Splunk App for Windows Infrastructure. A few simple practices can make a huge difference when it comes time to audit, analyze, or debug. Splunk’s web port used for web UI access. Information: Custom EventLogs on Splunk for Windows are discussed here. These events can be collected with a Splunk Universal Forwarder, and then sent to indexers which may be a central location. For large deployments, a stand-alone system is important. Live handson experience with Splunk and supportive document for references . Also be aware that there are significant differences in the event format of SEP events between versions (most notably versions 11 and 12), which may result in failed extraction of fields if your TA or current extractions are expecting a different version. This tool is installed by default on 2008 AD systems, but would need to be installed manually as part of the RSAT package on other versions of Windows. Some cookies may continue to collect information after you have left our website. You don't need to collect a baseline - or dump - of your Active Directory schema to use with the Splunk App for Windows Infrastructure.
