1 QRadar on Cloud overview

IBM QRadar on Cloud allows you to enjoy the benefits and customer support of IBM Security QRadar,but in a hosted deployment. In an environment where security requirements are dynamic, QRadar onCloud provides both the security monitoring that you need, and the flexibility to modify your monitoringas your requirements change. With QRadar on Cloud, you can use the capabilities of QRadar withoutinvesting in all of the required hardware and software of an on-premises QRadar deployment.

You connect to QRadar through a data gateway appliance. Other than the gateway appliance, you do notneed to install any extra hardware on your premises. Download and install the enabling software on yourgateway appliance to collect flow data, and events from all log sources that are supported on yourpremises or in the cloud. The enabling software forwards the collected events and flow data to QRadarrunning in the IBM cloud, through a secure VPN tunnel, where the data is stored and managed. Log onto the QRadar console from a web browser to manage all your security and threat management tasks, justas you would with QRadar deployed on your premises.

The following image shows devices on your network that send information to your gateway appliance.The gateway appliance then communicates with an instance of QRadar that is running in the IBM cloud.

Your data gateway appliance can collect 10,000 events per second (EPS) if you are not collecting flowdata. If you are collecting flow data and events, the following table provides limits for EPS and flows perminute (FPM).

You can have a maximum of six QRadar on Cloud users. You can give any of these users the securityadministrator access.

QRadar on Cloud provides IBM security professionals to manage the infrastructure, while your securityanalysts perform the threat detection and management tasks. You can protect your network, and meetcompliance monitoring and reporting requirements, with reduced total cost of ownership.

For more information about the capabilities of QRadar on Cloud, see “Capabilities in your securityintelligence product” in the IBM QRadar SIEM Administration Guide.

2 QRadar on Cloud onboarding

After you purchase IBM QRadar on Cloud, IBM sends you the information that is required for you to useQRadar on Cloud.

Gateway appliance prerequisites

You must meet the following prerequisites before you can use the QRadar on Cloud gateway appliance:v You must have the public host name of the console that you connect to through the gateway appliance.

You will receive this from IBM.v You must have your QRadar on Cloud token. You need a token for each gateway appliance that you

want to use to connect to QRadar on Cloud on the IBM cloud. Go to Admin > Hosted QRadar inQRadar to retrieve your token.

v You must have a download link to the IBM QRadar ISO for your gateway appliance. The downloadlink is at Admin > Hosted QRadar in QRadar.

v You must have a static IP address to connect to QRadar on Cloud through your gateway appliance. Donot use any IP address in the 192.168.0.0/16 network range.

v Your gateway appliance must be behind a network address translation (NAT) firewall.v If your gateway traffic is routed through a proxy server, it must be a transparent or inline proxy server

that does not challenge for authentication.v You must have adequate bandwidth to send your security data to QRadar on Cloud. On average, 0.72

Mbps is required for 1000 events per second (EPS), 7.2 Mbps for 10,000 EPS. Use the following formulato determine your bandwidth requirements:EPS * ((average event size + 200) bytes x 8) / (1000 x 1000 x 10) = Mbps value.

Example: 1000 * ((700 + 200) x 8) / (1000 x 1000 x 10) = 0.7 Mbpsv Your gateway appliance must meet the recommended system requirements.

Gateway appliance system requirements

The gateway appliance that you install on your premises communicates with QRadar on Cloud musthave the following specifications:

4 QRadar on Cloud work items that require a support ticket

IBM Security professionals manage your QRadar on Cloud infrastructure. Providing as much informationas possible can help IBM to better help you.

The following table describes the work items that require a support ticket.

Table 7. QRadar on Cloud work items

Work item DescriptionInformation that you need toprovide

Managing user accounts Add or disable user accounts. v Add an account: an email addressthat is associated with an IBMaccount, the user role, and thesecurity profile for each user.

v Disable an account: which useraccount to disable.

Managing user roles User roles determine what a user canaccess in QRadar.

The name of the user role, thesecurity profile for the user role, anda list of what you want users withthe user role to be able to access inQRadar.

For more information about userroles, see the IBM QRadar SIEMAdministration Guide.

Authentication Contact support for anyauthentication issues.

Generating tokens for gateways orauthorized services

QRadar requires authenticationtokens for appliances such asgateways, and to authenticate theAPI calls that apps make.

The name of the token, the user roleto assign to the token, and thesecurity profile for the token.

Whitelist changes An asset whitelist is a collection ofasset data that overrides the assetreconciliation engine logic aboutwhich data is added to an assetblacklist. When the system identifiesa blacklist match, it checks thewhitelist to see whether the valueexists. If the asset update matches thedata that is on the whitelist, thechange is reconciled and the asset isupdated. Whitelisted asset data isapplied globally for all domains.

Provide the network range inClassless Inter-Domain Routing(CIDR) format to add to, or removefrom, the whitelist.

Backup Configuration backup occurs nightly. The specific time to take the backupif it is scheduled outside of thenormal backup time.

Restore Restore a daily backup. The date of the backup to restore,from the last week.

System settings System settings are used to configuresettings for databases, authentication,Consoles, and more.

Which setting and value you want tochange. For more information aboutsystem settings, see the IBM QRadarSIEM Administration Guide.

Forwarding destinations and routingrules

You can configure QRadar systems toforward data to one or more vendorsystems, such as ticketing or alertingsystems. You can also forwardnormalized data to other QRadarsystems. The target system thatreceives the data from QRadar isknown as a forwarding destination.After you add one or moreforwarding destinations, you cancreate filter-based routing rules toforward large quantities of data.

Details about what to forward andwhere to forward it.
