The following topics describe how to specify user preferences:
Depending on your user role, you can specify certain preferences for your user account.
In a multidomain deployment, user preferences apply to all domains where your account has access. When specifying home page and dashboard preferences, keep in mind that certain pages and dashboard widgets are constrained by domain.
All user accounts are protected with a password. You can change your password at any time, and depending on the settings for your user account, you may have to change your password periodically.
If password strength checking is enabled, passwords must be at least eight alphanumeric characters of mixed case and must include at least one numeric character. Passwords cannot be a word that appears in a dictionary or include consecutive repeating characters.
If you are an LDAP or a RADIUS user, you cannot change your password through the web interface.
|
Step 1 |
From the drop-down list under your user name, choose User Preferences. |
|
Step 2 |
Enter your Current Password, and click Change. |
|
Step 3 |
In the New Password and Confirm fields, enter your new password. |
|
Step 4 |
Click Change. |
Depending on the settings for your user account, your password may expire. The password expiration time period is set when your account is created. If your password has expired, the Password Expiration Warning page appears.
|
On the Password Expiration Warning page, you have two choices:
|
You can specify the page within the web interface to use as your home page for the appliance. The default home page is the default dashboard (), except for user accounts with no dashboard access, such as External Database users. (See Specifying Your Default Dashboard to set the default dashboard.)
In a multidomain deployment, the home page you choose applies to all domains where your user account has access. When choosing a home page for an account that frequently accesses multiple domains, keep in mind that certain pages are constrained to the Global domain.
|
Step 1 |
From the drop-down list under your user name, choose User Preferences. |
|
Step 2 |
Click Home Page. |
|
Step 3 |
Choose the page you want to use as your home page from the drop-down list. The options in the drop-down list are based on the access privileges for your user account. For more information, see User Account Privileges. |
|
Step 4 |
Click Save. |
Use the Event View Settings page to configure characteristics of event views on the Firepower Management Center. Note that some event view configurations are available only for specific user roles. Users with the External Database User role can view parts of the event view settings user interface, but changing those settings has no meaningful result.
|
Step 1 |
From the drop-down list under your user name, choose User Preferences. |
|
Step 2 |
Click Event View Settings. |
|
Step 3 |
In the Event Preferences section, configure the basic characteristics of event views; see Event View Preferences. |
|
Step 4 |
In the File Preferences section, configure file download preferences; see File Download Preferences. |
|
Step 5 |
In the Default Time Windows section, configure the default time window or windows; see Default Time Windows. |
|
Step 6 |
In the Default Workflow sections, configure default workflows; see Default Workflows. |
|
Step 7 |
Click Save. |
Use the Event Preferences section of the Event View Settings page to configure basic characteristics of event views in the Firepower System. This section is available for all user roles, although it has little to no significance for users who cannot view events.
The following fields appear in the Event Preferences section:
The Confirm “All” Actions field controls whether the appliance forces you to confirm actions that affect all events in an event view.
For example, if this setting is enabled and you click Delete All on an event view, you must confirm that you want to delete all the events that meet the current constraints (including events not displayed on the current page) before the appliance will delete them from the database.
The Resolve IP Addresses field allows the appliance, whenever possible, to display host names instead of IP addresses in event views.
Note that an event view may be slow to display if it contains a large number of IP addresses and you have enabled this option. Note also that for this setting to take effect, you must use management interfaces configuration to establish a DNS server in the system settings.
The Expand Packet View field allows you to configure how the packet view for intrusion events appears. By default, the appliance displays a collapsed version of the packet view:
None - collapse all subsections of the Packet Information section of the packet view
Packet Text - expand only the Packet Text subsection
Packet Bytes - expand only the Packet Bytes subsection
All - expand all sections
Regardless of the default setting, you can always manually expand the sections in the packet view to view detailed information about a captured packet.
The Rows Per Page field controls how many rows of events per page you want to appear in drill-down pages and table views.
The
Refresh Interval field sets the refresh interval for
event views in minutes. Entering
0 disables the refresh option. Note that this interval
does not apply to dashboards.
The
Statistics Refresh Interval controls the refresh
interval for event summary pages such as the Intrusion Event Statistics and
Discovery Statistics pages. Entering
0 disables the refresh option. Note that this interval
does not apply to dashboards.
The Deactivate Rules field controls which links appear on the packet view of intrusion events generated by standard text rules:
All Policies - a single link that deactivates the standard text rule in all the locally defined custom intrusion policies
Current Policy - a single link that deactivates the standard text rule in only the currently deployed intrusion policy. Note that you cannot deactivate rules in the default policies.
Ask - links for each of these options
To see these links on the packet view, your user account must have either Administrator or Intrusion Admin access.
Use the File Preferences section of the Event View Settings page to configure basic characteristics of local file downloads. This section is only available to users with the Administrator, Security Analyst, or Security Analyst (Read Only) user roles.
Note that if your appliance does not support downloading captured files, these options are disabled.
The following fields appear in the File Preferences section:
The Confirm ‘Download File’ Actions check box controls whether a File Download pop-up window appears each time you download a file, displaying a warning and prompting you to continue or cancel.
 Caution |
Cisco strongly recommends you do not download malware, as it can cause adverse consequences. Exercise caution when downloading any file, as it may contain malware. Ensure you have taken any necessary precautions to secure the download destination before downloading files. |
Note that you can disable this option any time you download a file.
When you download a captured file, the system creates a password-protected .zip archive containing the file. The Zip File Password field defines the password you want to use to restrict access to the .zip file. If you leave this field blank, the system creates archive files without passwords.
The Show Zip File Password check box toggles displaying plain text or obfuscated characters in the Zip File Password field. When this field is cleared, the Zip File Password displays obfuscated characters.
The time window, sometimes called the time range, imposes a time constraint on the events in any event view. Use the Default Time Windows section of the Event View Settings page to control the default behavior of the time window.
User role access to this section is as follows:
Administrators and Maintenance Users can access the full section.
Security Analysts and Security Analysts (Read Only) can access all options except Audit Log Time Window.
Access Admins, Discovery Admins, External Database Users, Intrusion Admins, Network Admins, and Security Approvers can access only the Events Time Window option.
Note that, regardless of the default time window setting, you can always manually change the time window for individual event views during your event analysis. Also, keep in mind that time window settings are valid for only the current session. When you log out and then log back in, time windows are reset to the defaults you configured on this page.
There are three types of events for which you can set the default time window:
The Events Time Window sets a single default time window for most events that can be constrained by time.
The Audit Log Time Window sets the default time window for the audit log.
The Health Monitoring Time Window sets the default time window for health events.
You can only set time windows for event types your user account can access. All user types can set event time windows. Administrators, Maintenance Users, and Security Analysts can set health monitoring time windows. Administrators and Maintenance Users can set audit log time windows.
Note that because not all event views can be constrained by time, time window settings have no effect on event views that display hosts, host attributes, applications, clients, vulnerabilities, user identity, or compliance white list violations.
You can either use Multiple time windows, one for each of these types of events, or you can use a Single time window that applies to all events. If you use a single time window, the settings for the three types of time window disappear and a new Global Time Window setting appears.
There are three types of time window:
static, which displays all the events generated from a specific start time to a specific end time
expanding, which displays all the events generated from a specific start time to the present; as time moves forward, the time window expands and new events are added to the event view
sliding, which displays all the events generated from a specific start time (for example, one day ago) to the present; as time moves forward, the time window “slides” so that you see only the events for the range you configured (in this example, for the last day)
The maximum time range for all time windows is from midnight on January 1, 1970 (UTC) to 3:14:07 AM on January 19, 2038 (UTC).
The following options appear in the Time Window Settings drop-down list:
The Show the Last - Sliding option allows you configure a sliding default time window of the length you specify.
The appliance displays all the events generated from a specific start time (for example, 1 hour ago) to the present. As you change event views, the time window “slides” so that you always see events from the last hour.
The Show the Last - Static/Expanding option allows you to configure either a static or expanding default time window of the length you specify.
For static time windows, enable the Use End Time check box. The appliance displays all the events generated from a specific start time (for example, 1 hour ago) to the time when you first viewed the events. As you change event views, the time window stays fixed so that you see only the events that occurred during the static time window.
For expanding time windows, disable the Use End Time check box. The appliance displays all the events generated from a specific start time (for example, 1 hour ago) to the present. As you change event views, the time window expands to the present time.
The Current Day - Static/Expanding option allows you to configure either a static or expanding default time window for the current day. The current day begins at midnight, based on the time zone setting for your current session.
For static time windows, enable the Use End Time check box. The appliance displays all the events generated from midnight to the time when you first viewed the events. As you change event views, the time window stays fixed so that you see only the events that occurred during the static time window.
For expanding time windows, disable the Use End Time check box. The appliance displays all the events generated from midnight to the present. As you change event views, the time window expands to the present time. Note that if your analysis continues for over 24 hours before you log out, this time window can be more than 24 hours.
The Current Week - Static/Expanding option allows you to configure either a static or expanding default time window for the current week. The current week begins at midnight on the previous Sunday, based on the time zone setting for your current session.
For static time windows, enable the Use End Time check box. The appliance displays all the events generated from midnight to the time when you first viewed the events. As you change event views, the time window stays fixed so that you see only the events that occurred during the static time window.
For expanding time windows, disable the Use End Time check box. The appliance displays all the events generated from midnight Sunday to the present. As you change event views, the time window expands to the present time. Note that if your analysis continues for over 1 week before you log out, this time window can be more than 1 week.
A workflow is a series of pages displaying data that analysts use to evaluate events. For each event type, the appliance ships with at least one predefined workflow. For example, as a Security Analyst, depending on the type of analysis you are performing, you can choose among ten different intrusion event workflows, each of which presents intrusion event data in a different way.
The appliance is configured with a default workflow for each event type. For example, the Events by Priority and Classification workflow is the default for intrusion events. This means whenever you view intrusion events (including reviewed intrusion events), the appliance displays the Events by Priority and Classification workflow.
You can, however, change the default workflow for each event type. The default workflows you are able to configure depend on your user role. For example, intrusion event analysts cannot set default discovery event workflows.
This setting determines the times displayed in the web interface for your user account only, for things like task scheduling and viewing dashboards. This setting does not change the system time or affect any other user, and does not affect data stored in the system, which generally uses UTC.
 Warning |
The Time Zone function (in User Preferences) assumes that the system clock is set to UTC time. DO NOT ATTEMPT TO CHANGE THE SYSTEM TIME. Changing the system time from UTC is NOT supported, and doing so will require you to reimage the device to recover from an unsupported state. |
