CAPTCHA Settings

A login CAPTCHA serves as a security measure against bot-based brute force attacks. Enabling this setting will display a CAPTCHA image on the login page. End-users must enter the characters shown in the CAPTCHA image to log into the Log360 UEBA web portal.

You can configure whether you want the user to always input a CAPTCHA, or you want them to input a CAPTCHA only after a certain number of invalid login attempts. Apart from the CAPTCHA image, you can also enable Audio CAPTCHA to assist visually impaired users.

Steps to enable CAPTCHA

Log into Log360 UEBA as an administrator.
Go into the Settings tab
Navigate to Settings → Logon Settings, and click the General tab.
Select the option Enable CAPTCHA on the login page.
Select Always show CAPTCHA if you want users to go through CAPTCHA verification every time they login.
Select Show CAPTCHA after invalid login attempts if you want only those users who failed at login to go through the CATPCHA verification process.

Enter the number of invalid login attempts after which the CAPTCHA verification should appear.
Enter the threshold (in minutes) to reset the invalid login attempts. After the specified time period, the invalid login attempts will be reset.
Example: Consider the following limits:

Invalid login attempts limit is set to ‘3’ times
Reset limit after is set to ’30’ minutes
In this example, if a user fails to login 3 consecutive times in a 30-minute time interval, then a CATPCHA image will be displayed. The user now has to enter the correct credentials, plus the characters shown in the CAPTCHA image, to successfully log into Log360.

Select Enable Audio CAPTCHA to assist visually impaired users.

Note: When audio CAPTCHA is enabled, only digits will be shown in the CAPTCHA image. If a browser doesn’t support audio CAPTCHA, then the default CAPTCHA image (with letters and digits) will be shown.

Click Save Settings.

Block Users Settings

Using this option you can block users from accessing Log360 UEBA after a certain number of invalid login attempts for a defined time interval. A blocked user cannot log into Log360 UEBA.

Steps to block users:

Log into Log360 UEBA as an administrator.
Navigate to Settings → Logon Settings, and click the General tab.
Select the option Block users after invalid login attempts.

Enter the number of invalid login attempts after which users should be blocked.
Enter the threshold (in minutes) to reset the invalid login attempts. After the specified time period, the invalid login attempts will be reset.
Enter the number of minutes users should be blocked.
Example: Consider the following limits:

Invalid login attempts limit ‘3’ (times) within ‘5’ minutes.
Reset the invalid attempts limit after ’30’ minutes
In this scenario, if a user fails login 3 times in a 5-minute time interval, then the user will be blocked from logging into Log360 UEBA for 30 minutes.

Allow/Restrict IPs

The security layer of Log360 UEBA can be reinforced by restricting inbound connection requests to the product. This feature of Log360 UEBA can be configured to only allow connections from trusted IPs and IP ranges, and block other unnecessary and malicious traffic. This restriction can apply to APIs used to access the product and certain URLs of the product that are critical in nature, for which access should be restricted.

Steps to allow or restrict IPs

Login to Log360 UEBA.
In the Settings tab, select Logon settings.
Select Allow/Restrict IPs tab.
Under the Actions column, click the [] icon to enable IP restriction.

Allow/Restrict IPs

In the pop up, select Allowed IPs or Restricted IPs as per requirements.

To specify an IP range, enter the start and end IP addresses of the range in the Allow IP Range field. To add another range, click the [+] icon.
To specify individual IP addresses, click the Add Individual IPs option and enter the desired IP address. Add multiple individual IP addresses by separating the values using a comma.

(Refer to Appendix for more information.)

Controlling access to APIs and product URLs

Login to Log360 UEBA.
In the Settings tab, select Logon settings.
Select Allow/Restrict IPs tab.
Under the Actions column, click the [] icon to enable IP restriction.

Allow/Restrict IPs

In the pop up, check the Enable API/URL Access for Selected IPs box.
Enter the API/Product URLs in the box provided.

Sample URL paths: /Admin.do, /Configuration.do, /Dashboard.do

Sample API paths: /RestAPI/WC/Integration, /RestAPI/WC/LogonSettings

Note:

Use * as a wildcard character to restrict access to a broader range of APIs or URLs. For example, use /RestAPI/WC/* to restrict all API calls that start with /RestAPI/WC/.
The API/URL path should start with /. For example, /Admin.do and /RestAPI/WC/.
Enter only the path of the API or URL. For example, if the entire product URL is https:testserver:8082/Admin.do, then enter only /Admin.do.
Only alphanumeric (A-Z,a-z, 0-9) and special characters—period (.), slash (/) and asterisk (*)—are allowed.

To specify an IP range, enter the start and end IP addresses of the range in the Allow IP Range field. To add another range, click the [+] icon.

Allow/Restrict IPs

Click Save to save the settings.
If you have changed the proxy settings for which you are enabling IP-based restriction, then:

Add the following line to the server.xml file (default location:
<InstallationDirectory>/conf/server.xml).

<Valve className="org.apache.catalina.valves.RemoteIpValve"

internalProxies="192\.168\.0\.10|192\.168\.0\.11"

trustedProxies="172\.168\.0\.10|176\.168\.0\.11" />

Edit the values of internalProxies and trustedProxies as per your environment.
Enter IP address while specifying the values for internalProxies and trustedProxies, and use the vertical bar (|) character to enter multiple values.

Restart UEBA for the changes to take effect.
Repeat steps a and b for the integrated components as well.

Managing IP restrictions

Disable/enable IP-based restriction: Use the icon under the Actions column to enable or disable IP-based restriction. [] icon means IP-based restriction is enabled for a component and [] icon means IP-based restriction is disabled.
Edit IP-based restriction settings: Click [] icon to add, delete, or edit the IP ranges and individual IP addresses.
Summary details: Click [] the link under the Allow/Restrict IPs column to view the IPs that are allowed or restricted from accessing a component.

Appendix

Use * as wildcard character: Individual IP addresses can include wildcard characters, so that all addresses within a certain class of address will be restricted. For example, denying access to address 192.168.2.* denies access to all addresses for that subnet.
You can also enter hostname instead of IP addresses.
You can allow or restrict only IPv4 addresses. IPv6 is not supported.
