These tables define the event dimensions for events in SIA.

For threat events in the Threat Events report, you can choose to show data based on this criteria:

Dimensions for Threat Events

Dimension	Definition
Category	The overall category of the event. For a threat event, categories can be Malware, Phishing, C&C, DNS Exfiltration, Deny List, or Other (if assigned to a custom list).
Reason	Informs how an event was identified. Any of these reasons may appear: Akamai Intelligence. Indicates the event was identified by Akamai or a threat category. Customer Domain Intelligence. Indicates the event was found for a domain based on a list configuration. Customer URL Intelligence. Indicates the event was found for a URL based on a list configuration. Sandbox-Dynamic Analysis. Indicates the event was found with dynamic malware analysis. AV scan. Indicates the event was found with inline payload analysis. Data Leakage Prevention. Indicates the event was found as a result of a DLP configuration. Additionally, if the event was detected as a result of AVC, these reasons may also be listed depending on the policy action assigned to these areas: Application Risk Level. Indicates the event was detected based on the risk levels associated with the policy. Category. Indicates the event was detected based on the category or categories associated with the policy. Application category operation. Indicates the event was detected based on the category operations associated with the policy. Application. Indicates the event was detected based on applications associated with the policy. Application Operation. Indicates the event was detected based on application operations associated with the policy.
Severity	Indicates the severity level. For more information, see Severity levels. This criteria or dimension appears for threat events only.
Location	A location is a public IP address or a named collection of public IP addresses that belong to a region or geographic area in your network, such as a CIDR block for an office branch or company headquarters. The location indicates where the event originated from.
Policy	Security policy or set of rules that are associated with a location.
Domain	Domain or IP address requested by the user.
Resolved IP	IP address that is resolved from a domain name.

Action	Action taken on known or suspected threats based on a policy configuration.
Confidence	Indicates whether an event is a known or suspected threat.
Device Risk Level	Device posture risk level of the user’s device. To show a value for this dimension, your organization must be set up for device posture in Enterprise Application Access. You must also select device risk levels as part of your AVC configuration for accessing web applications or completing an application operation. For more information, see Use device posture for application access.
DoH Attribution	ID of the device where DNS over HTTPS (DoH) is enabled. An administrator can provide this ID for a user device when setting up DoH. For more information, see Encrypt DNS queries with DoT or DoH.
Source IP	IP address of traffic. This is likely the IP address that is assigned to a location as a result of NAT.
Sub-Location	Indicates the sub-location where the event originated from.
Client Request ID	Universally unique identifier (UUID) of ETP Client that’s installed on the machine.
Autonomous System	A unique identifier for a network.
Detection Method	Indicates how the event was detected. This field may show any of these values: Inline. Indicates the event was detected at the time of access. Lookback. Indicates the event was discovered in log data based on behavior. Offline Static. Indicates the event was discovered offline or after content was downloaded as a result of static malware analysis. Offline Dynamic. Indicates the event was discovered in a sandbox environment as a result of dynamic malware analysis.

Transport Type	Indicates how DNS traffic was transported to SIA. This field may show one of these values: dou. Indicates that DNS traffic was transported over UDP. dot. Indicates that DNS traffic was transported with DNS over TLS. doh.Indicates that DNS traffic was transported with DNS over HTTPS.
Onramp Type	Indicates how a request was directed to SIA Proxy. One of these values may appear: dns. Indicates DNS event was forwarded to SIA Proxy. web. Indicates web (HTTP and HTTPS) request was forwarded to the full web proxy. onramp_dns. Indicates that risky HTTP and HTTPS traffic was forwarded to the selective proxy. etp_client. Indicates the request was directed to SIA Proxy as a result of ETP Client. etp_offnet_client. Indicates the request was directed to SIA Proxy as a result ETP Client. In this case, ETP Client was off the corporate network. explicit_proxy_tls. Indicates the request was directed to SIA Proxy as a result of an on-premises proxy configuration.
Internal Client IP	Internal IP address of the user’s machine.
Internal Client Name	Internal client name of machine that’s detected by DNS Forwarder.
User Name	If authentication is enabled in a policy, this dimension shows the username of the user who made the request.
Device Owner	Owner of the device where ETP Client is installed. This is the username or email address of the user who activates ETP Client on their device. This username or email address is associated with the device in SIA reports.
Dictionaries	The specific dictionary that’s used to scan uploaded content for DLP.
Patterns	The pattern in a dictionary that’s used to scan uploaded content for DLP.
File Hash	The hash of the uploaded file that’s scanned by DLP and detected to include sensitive information.
File Type	MIME file type that is downloaded or uploaded. An administrator may assign the block or monitor action to this file type in a policy.
Threat Name	Name of the threat. If a specific name for a threat does not appear, SIA shows a name that classifies the threat. These classifications include: Customer Lists. Domains or IP addresses in a custom list. The domains or IP addresses in these lists are defined by your organization. Known Phishing. Domains or URLs that are used in a social engineering attack to fraudulently obtain personal or classified information. A phishing scam deceives victims to performing an activity that compromises their machine or reveals sensitive information. Known Malware. Domains or URLs that direct victims to malicious websites or are used by applications to harm a network. Malware steals confidential data, compromises data integrity, and disrupts data availability. Known CNC. Domains or URLs that are used for C&C communication. A C&C threat is used to steal data, distribute malware, and disrupt services. File Sharing. Domains or URLs of file sharing services. Aged Out. Indicates the domain was tracked as a threat for some time and it may still be a threat. If the proxy is enabled, the proxy determines whether the domain is still a threat. Generic Risky. Indicates there's risk that the domain may be malicious. If the proxy is enabled, the proxy determines whether it is malicious. Unclassified Indicates a threat is not yet classified by SIA. This criteria or dimension appears for threat events only.
HTTP Request Method	The action that’s performed during the request. This attribute is available only when SIA Proxy is enabled.
URI	Uniform Resource Identifier. Characters or string that identify a resource. For example, a URL is a URI. This attribute is available only when SIA Proxy is enabled.
