Evaluating SIEM – What you need to know?

how-to-prepare-for-a-trip-L-HTeG64

We, at Infosecnirvana have published several posts on SIEM. SIEM as a product has created a unique place for itself in the IT Defense in Depth Strategy and has helped several organizations to effectively detect and respond to security threats as well as rapidly achieve compliance needs. Such an important product in the Security space also has a steep price attached to it. The price is not only in dollar terms, but also in ongoing human effort to manage, maintain and generate value out of it. So it becomes paramount that a right choice is made when it comes to SIEM. This blog post aims to give a set of product evaluation criteria or set of questions customers should ask in the evaluation of SIEM. This guide is using a vendor agnostic approach.

Introduction: 

Before selecting a SIEM vendor we need to make sure that the product meets certain selection requirements. Often times, IT organizations have only a vague idea of what is required from a SIEM. They don’t have a solid understanding of the various parameters to be considered in selecting SIEM products. Some of the key requirements to be considered are as follows:

  1. Company & Product
  2. Architecture
  3. Installation & Configuration
  4. Event Collection
  5. Event Storage
  6. User Interface & User Experience
  7. Certifications

Company & Product:

A SIEM product or any other software product for that matter is as good as the company that develops it. This is key because, a company that is stable and has a long term road map focusses better on product development and building expertise. Hence, evaluating the company also becomes important when buying the product. Some of the key items to look for are:

  • Industry Focus, Market presence, Years of experience in the field
  • Financial Performance – Subjective Measurements over the past years
  • Marketplace opinions and reviews about the product and the company as a whole.
  • Do they have customer references for both the product as well as the company?
  • Analyst Reports for the last few years – Gartner, Forrester etcetera.
  • Know the Executive Leadership of the Company. Is the leadership team strong? Is it Trustworthy?
  • Do they have a track record of successful product launches, revisions, development etcetera.
  • Licensing and Pricing models
  • How strong is their product road map?
  • $$$$ spent on R&D for new products VERSUS Development on incremental growth of core product.
  • Is the vision of the product group forward thinking? Are they innovative?
  • How is the Company’s product support and services group? Is it a dedicated team in house or is it outsourced?
  • What are the product support & professional services options available? How focused is the management team in providing Support services? Is support available globally?
  • Is there expertise across the vendors partners (VAR, MSSP, Consulting Organizations) to support both basic and advanced consulting needs? How mature is the partnership or alliance relationship?

Architecture: 

One of the key components of a product is its architecture maturity. The product should be capable of catering to IT Infrastructure needs that vary from industry to industry, from enterprise to enterprise. Some of the key questions related to Architecture are listed below:

  • How flexible is the product deployment architecture? Can it be run as an Appliance, a Software standalone, a virtual appliance/machine or a SaaS?
  • Can the architecture be deployed in a way where individual data storage capability is available per business unit/location?
  • Does the architecture allow for full data replication for HA purposes? Is HA a built-in function or additional equipment is required?
  • Does the architecture allow for interoperability with Network Management devices, System Management devices etcetera.
  • Does the architecture support scalability? Is it modular enough to expand based on growth needs, storage needs and performance needs?
  • Does the product support granular Role based Access control for the underlying hardware & application software?
  • Does it meet the organization’s policy and standards compliance requirements
  • Does the product have a secure data transmission between Event Collection, Event Storage and Event Correlation layers? Does it use encryption? If so, how strong?

Installation & Configuration: 

  • Can the Installation and Initial Configuration be handled by technical staff with minimal training?
  • Ease of set-up, Maturity of Product Documentation and Support to facilitate this effort?
  • Ease of post install maintenance, patching, routine tuning?
  • Ease of patch management of the product including the underlying data architecture.
  • How does the product or solution facilitate asset tracking?
  • From a log collection perspective, who are the supported Vendors, what Products and Versions are supported for integration?
  • How varied and comprehensive is the Data export feature (extract logs, alerts, raw data etcetera.)? Does it support CSV, PDF, HTML, Raw text etcetera?
  • Data Workflow Integration (Bidirectional access to information via external workflow tools?)
  • Email interface for report distribution, ease of customization of the email templates
  • Interface to 3rd party applications (ticketing/workflow application, existing business logging solutions etcetera.)

Event Collection:

  • Does the product have support for both Agent based Collection and Agent-less Collection?
  • For Agent systems, does the solution support Windows, Unix and Linux Platforms, File readers, XML readers, Structured and unstructured data etcetera.
  • For Agent-less, does the solution support Syslog, SNMP, SQL, ODBC/JDBC,  and API collection
  • Is the Agent management function centralized or is it standalone?
  • Does it have any limitations in Input and Output Events Per Sec (EPS)?
  • Does it offer the following capabilities to ensure reliability and flexibility?
    1. Aggregation – Can the Agent aggregate similar information based on custom defined grouping values defined by the System Administrator to cater to the changing Event Collection requirements?
    2. Bandwidth Throttling – Can the Agent prioritize forwarding of events based on defined values such as event priority? Can it send events at a specific bandwidth rate
    3. Filtering – Can the agent provide Include as well as Exclude criteria for filtering?
    4. Caching – Can the agent cache all the events in the event that the Log Store goes down? When forwarding the cache after failure does it intelligently throttle the events?
    5. Fail-over Capabilities – Can the agent send Log events to a different alternate data store when the principal data store is down? Can it do multiple destination forwarding?
    6. Transport Integrity – Can the agent encrypt the log transport to ensure confidentiality? What compression and encryption mechanisms are used?
    7. Health Monitoring – Can the agent send health messages and statistics?
  • For Microsoft Windows Event collection can the agent map the GUID/SUID to local registry/names/references for each event ID in the SYSTEM, SECURITY and all APPLICATION logs on the system?
  • Are Agents that rely on Event Source Vendor API’s to connect and collect information approved and/or certified by that event source Vendor?
  • Can the Agent follow dynamically changing folders and file names? For example in order to support event sources like IIS Web Logs or custom applications that create a log per “site/application” per logging interval?
  • Does the Agent support Database Administrator Logging (From both SQL and System / File Based Sources) for Oracle, MSSQL, MySQL and DB2?
  • Agent parsing and mapping customization. Can the agent’s parsing be modified to assist with custom log messages? Can the normalization or categorization schema be updated to support custom log messages? How is system default functionality affected if these are modified?
  • Can the Agent act as a NTP source for Source Event Logs or otherwise help in time synchronization for source event logs?
  • Time difference adjustment feature (to allow the logging system to cope with devices having inconsistent times)

Event Storage:

  • Does the product allow storage of data locally, remotely in a SAN or NAS?
  • Is the data storage capable of compression? If so what is the rate of compression?
  • Is the storage architecture dependent on standard database or does it use proprietary architecture? If proprietary, does it have all the capabilities to meet storage security requirements?

Conclusion: Phew!!! That is a long list of things to consider for SIEM evaluation and I still feel that there are many items I am missing from this list. As mentioned at the beginning, this post is a guide to perform SIEM evaluation and should be a great starting point in terms of a check list creation, Tender floatation, proposal requests and the like. Please feel free to add in the comments section or send me an message if you feel any more items need to be added.

Until next time!!! Ciao
