Agenda Introduction Best practices Management tool Use cases Discussion and Q&A 2
Introduction
HP ArcSight Next Generation Cyber Defense Visualize Search Predict SIEM Analytics Collect Respond Correlate 4
Introduction Why is manageability important for security? Ensure security policies are Followed And Enforced Manage the deployment holistically and not just individual elements Monitor, create alert, and maintain the security operations Deliver efficient and timely implementation Enable resources to focus on security analysis 5
Best practices
Best practice Create Golden Configuration Create Groups Monitor critical events and set alerts Update to the latest ArcSight product release ASAP Backup regularly Review and audit changes Leverage the ArcSight user community in Protect724 7
Management tool
Management tool What are the benefits of using management tools? Reduce cost Faster and reliable implementation of security policy Increase accuracy Enable resource to focus on security analytics What is the name of the ArcSight management tool? ArcSight Management Center 9
HP ArcSight Management Center ArcSight Management Center (ArcMC) delivers centralized enterprise management that simplifies the deployment and maintenance of the desired enterprise security posture in a cost effective and efficient manner. 10
ArcSight Management Center (ArcMC) ArcMC Version 2.0 ArcMC ArcMC ConApp Connector Logger 11
A few definitions A host is a system that hosts at least on ArcSight product A node is a managed ArcSight product Connector Connector appliance ArcSight Management Center Logger Node can be software or hardware form factor A configuration listed in ArcMC is considered a golden configuration Subscriber are the nodes which can receive the golden configuration. When subscriber s configuration is identical to the golden configuration, it is considered compliant. Otherwise, it is non-compliant. 12

Use cases Configuration management Management using groups Update to the latest Software Monitoring
Use cases Configuration management
ArcMC paradigm of operation Step 1 Create/import configuration in ArcMC Step 2 Add subscribers to the configuration Step 3 Push configuration to subscribers Step 4 Check compliance 16
Use cases Configuration Management 17
Use case: Schedule regular configuration backup Configure all the appliances to do backup on same schedule, i.e., every Saturday at 10 p.m. ArcMC 18
Use case: Logger filters Logger Filter Add new filter query - Create filters once on one Logger and wants to have the same filters on the rest of Loggers w/o re-creating them on other Loggers ArcMC 19
Use case: User management Add new employee - Create the same users on all the Appliances, software or hardware form factor Add new appliances, for example multiple ArcMC or multiple Loggers need to add existing users to the new appliances. ArcMC Software Connector Appliances, logger and ArcMC 20 Connector Appliances, ArcMC, Logger
Use case: Window Unified Connector configuration Software Connector HP ArcSight HP ArcSight Push Window Unified Connector configuration to multiple Window Unified Connectors (WUC) HP ArcSight Run compliance check to ensure the configurations are indeed on the SmartConnectors ArcMC 21 Connector Appliances
Use case: DNS Management DNS server Add a new DNS server across all ArcSight Appliances Add a new DNS server to a logical group by location or function ArcMC 22
Use case: Compliance check X Is my environment compliant with FIPS? Compliance check can be extended, for example, Is the configuration compliant with the baseline golden configuration? following the corporate policy? ArcMC ArcSight ArcSight X X ArcSight ArcSight ArcSight ArcSight X 23
Supported Logger configurations Logger Logger Configuration Backup Logger Smart Message Receiver Logger Transport Receiver Logger Storage Group Logger Filter 24
Supported Connector and ConApp and ArcMC configurations Connectors FIPS Map Files Parser Override Syslog Connector Window Unified Connector Bluecoat Connector Appliance and ArcMC Conapp/ArcMC Configuration Backup 25
Supported System Admin configurations Software Authentication External Authentication Local Password Authentication Session User Configuration SMTP Hardware DNS NTP Network SNMP 26
Use cases Management using groups
Bulk add host- Import hosts Allows adding hosts in bulk from a Comma Separated Values (.csv) file Background batch job Requirement:.csv file with valid host entries Results of import hosts job will be stored in a text file at <install_dir>/userdata/arcmc/importhosts/ 28
Create CSV File for bulk add host 29
Bulk add host using import CSV Import Host CSV File 30
ArcMC node management A node is a managed ArcSight product Connector Connector Appliance Logger ArcMC Nodes can be software or hardware form factor 31
Use cases Update to the latest software
Use case: Update software to the latest release New ArcSight software release - Push new versions of software to connectors, ArcMC appliances and logger appliances. HP ArcSight HP ArcSight HP ArcSight ArcMC 33
Demo Update software to the latest release 34
Use cases Monitoring
Monitoring nodes ArcMC 2.0 will support monitoring for Connector Appliance (hardware and software) Logger Appliance (hardware and software) Local and Managed ArcMCs (hardware and software) Smart Connectors 36
Health data monitored ArcMC collects health data from managed products in 1-min, 5-min and 1-hour time intervals to support charting and alert generation. CPU Memory Disk Network EPS In/Out Event and Queue Stats Thread Count Fan, Voltage, Power Supply, Temperature, RAID 37
Critical alert generation Breach rules are defined to generate alerts against health data metrics. Example: Generate a FATAL alert for any Logger whose average CPU usage in the past 5 minutes is greater than 90% breach.rule[1].product = LOGGER breach.rule[1].severity = FATAL breach.rule[1].metric = CPU breach.rule[1].aggregation = AVG breach.rule[1].measurement = GREATER breach.rule[1].value = 90 breach.rule[1].timespan = 5 38
Monitoring levels Summary Displays alerts / breaches across all the managed products Displays per product severity / alert pie charts 39
Monitoring levels Aggregated per managed product Displays alert / breaches of particular product type 40
Monitoring levels Individual product Displays alert / breaches on a managed node Displays different health monitor stats (EPS In/ Out, CPU, Memory Utilization, Hardware Stats) 41
