FortiSIEM Dynamic Population of Location, User, and and Geolocation Information for Events

Dynamic Population of Location, User, and and Geolocation Information for Events

In most cases, network logs only contain IP address information, but to investigate incidents involving that IP, you need additional context for that IP address such as host name, user, and geolocation information. Because FortiSIEM collects detailed IT infrastructure information in the CMDB, it is able to correlate that information to the IP address to create a context for the event, and insert that context information into events in real time as parsed attributes. This topic describes the way in which this context information is populated into events.

Correlating Event Information

Event information is derived from several different sources.

  1. During the discovery process, FortiSIEM discovers the host name and network interface address information during discovery and stores them in the CMDB. If any IP address other than the Access IP changes, then running a rediscovery will update the CMDB with the right information.
  2. FortiSIEM collates information from various authentication logs and forms a time-based Identity and Location Report containing the IP address, MAC address, Host Name, Domain, User, Network Access Point, and Network Access Point Port for the event.
  3. The geolocation database maps IP addresses to Country, State, City, Organization, Longitude, and Latitude information.

Assigning Attributes to Events

When FortiSIEM parses an event, attributes are assigned to it following this process:

Host Name Attribute

For each IP address (Host IP, Source IP, Destination IP, Reporting IP):

  1. FortiSIEM checks the CMDB for an associated host name, and if one is found, then the host name is added to the event.
  2. If the host name is not found in then CMDB, then FortiSIEM checks the Identity and Location Report for the host name, and if one is found, then it is added to the event.
  3. If the host name is not found in either the CMDB or Identity and Location Report, then FortiSIEM runs DNS lookup for the host name, and if one is found, then it is added to the event. For performance reasons the DNS result is cached, and because excessive DNS lookups can cause event processing delays, FortiSIEM has an algorithm to dynamically bypass DNS lookup if it begins falling behind in event processing.

User Name Attribute

For Source IP, FortiSIEM checks for user information in the Identity and Location Report, and if anything is found, it is added to the event.

Geolocation Attribute

For each IP address (Host IP, Source IP, Destination IP, Reporting IP), FortiSIEM checks the geolocation database. If geolocation information is found for that IP, then  Country, State, City, Organization, Longitude, and Latitude information is added to it.

Dynamic Updating of Attribute Information

For any of these attributes, when there is a change in the infrastructure (for example, a network device has a new IP or a new user logs on to the system), the change is populated into the CMDB and/or Identity and Location Report, and the event parsing module learns of the change and starts populating events with the new metadata.

Because the FortiSIEM approach to populating event attributes is dynamic and change driven, it is always able to map the right IP address to host names and users in the face of dynamic changes in the IT infrastructure.

Exporting Events to Files

You can run the phExportEvent tool from a Supervisor or Worker node to export events to CSV files. The file will contain these fields:

phExportEvent Command Description
DESTINATION_DIR Destination directory where the exported event files are saved
START_TIME Starting time of events to be exported. The format is YYYY-MM-DD HH:MM:SS {+|-} TZ. If TZ is not given, local time zone of the machine where the script is running will be used. Example: 2010-03-10 23:00:00 -8 means Pacific Standard Time, 23:00:00 03/10/2010. 2010-07-29 10:20:00 +5:30 means India Standard Time 10:20:00 07/29/2010.
RELATIVE_START_TIME Starting time of events to be exported relative backward to the end time as specified using –endtime END_TIME

. The format is

where NUM is the number of days or hours or minutes. For example, –relstarttime 5d means the starting time is 5 days prior to the ending time.

END_TIME Ending time of events to be exported. The format is the same as START_TIME.
RELATIVE_END_TIME Ending time of events to be exported relative forward to the start time as specified using START_TIME. The format is same as RELATIVE_START_TIME.
DEVICE_NAME Host name or IP address of the device with the events to be exported. Use a comma-separated list to specify multiple IPs or host names, for example, –dev 10.1.1.1,10.10.10.1,router1,router2. Host name is case insensitive
ORGANIZATION_NAME Used only for multi-tenant deployments. The name of the organization with the events to be exported. To specify multiple organizations, enter a commandeach for one organization, for example, –org “Public Bank” –org “Private Bank”. The organization name is case insensitive.
TIME_ZONE Specifies the time zone used to format the event received time in the exported event files. The format is {+|-}TZ, for example, -8 means Pacific Standard Time, +5:30 means India Standard Time.

FortiSIEM Device Risk Score Computation

Device Risk Score Computation

Risk computation algorithms are proprietary and this section presents only the knobs that user is able to tweak to change the score.

Risk score components

The following factors affect risk score of a device

  1. Device Importance (also called Asset Weight)
  2. Count and CVS Score for non-remediated vulnerabilities found for that device
  3. Severity and Frequency of Security incidents triggering with that device as source or destination
  4. Severity and Frequency of Other (performance, availability and change) incidents triggering on that device

Overall Score (0-100) is a weighted average of 3 components – Vulnerability Score, Security Incident Score and Other Incident Score, computed as follows.

User controllable constants
  1. Device Importance – this can be set in CMDB > Device > Summary. You can select multiple devices and set the Importance in one shot.

Values are

  1. Mission Critical – 10
  2. Critical – 7
  3. Important – 4
  4. Normal – 1
  1. Relative weights of Vulnerabilities, Security and Other incidents to the risk score. The default values of the constants are defined in phoenix_config.txt:
    1. vul_weight = 0.6
    2. security_inci_weight = 0.3
    3. security_inci_weight = 0.1
  2. Maximum number of high-severity events that a mission-critical host can tolerate for each of the 3 score components. These default thresholds are defined in ‘phoenix_config.txt:
    1. vul_threshold = 1
    2. security_inci_threshold = 3
    3. other_inci_threshold = 6
Time varying Risk score

Risk scores are computed for each day. Current risk score is a exponentially weighted average of today’s risk and yesterday’s risk.

The algorithm also reduces the score for earlier vulnerabilities that are now patched. Such vulnerabilities have a weight of 0.7 while new and old but existing vulnerabilities have weight 1

New Videos Incoming

Wanted everyone to know that I am still alive and well. Been moving and getting situated at the new location and just haven’t stayed disciplined enough over the past two months or so to when it comes to making video content.

Anyways, more videos should be incoming and if you have any suggestions please don’t hesitate to let me know.

I am also half tempted to start doing podcasts. Never done one but I am sure I could figure something out there.
