Capturing host names

Host identifiers are HTTP response headers that contain the host names of web servers that provide content for your monitored applications. Archivers insert the host name into all URLs. In some monitored environments, you may need to configure host identifiers for the session replay feature to work properly.
To create host identifiers, you need to complete the following tasks:
•
Configure each web server to insert a response header that contains the server’s host name (for example, quest.com). For information about how to insert a response header tag into outgoing traffic, see your web server documentation.
•
Configure a host identifier with the same response header. For instructions, see Defining identifiers.

Managing private keys

Private keys enable the system to monitor encrypted web traffic. To decrypt HTTPS traffic, Sniffers need access to the same private keys used to encrypt the data. Private keys can be stored locally or in a Hardware Security Module (HSM) appliance.
To load and manage private keys, navigate to APM > Configure > Traffic Capture > Private Keys.

In the Private Keys dashboard, you can perform the following tasks:

Managing local private keys
•
Managing HSM private keys

Managing local private keys

For each secure IP address that you want to monitor, you need to export the keys as encrypted private key files. When adding a private key in Foglight, you need both the encrypted key file plus the passphrase used when encrypting the key file.
Supported encryption technologies
Before you begin adding private keys, you need to ensure that Foglight APM supports the same encryption technologies in use within your network environment. Private keys need to be encrypted using a supported encoding format. In addition, the Sniffers and your secure servers need to use the same protocols and algorithms for secure communication. They need to establish a session using the same cryptographic protocol (such as TLS) and the same key exchange algorithm (such as RSA). They also need to use the same bulk encryption algorithm (such as RC4) for transmitting secure data.
The following table summarizes the supported technologies.

Diffie-Hellman is not supported because this key exchange algorithm cannot be decrypted by third-party monitoring tools. If you want to monitor the SSL traffic protected by Diffie-Hellman, disable all versions of Diffie-Hellman on the web server (or SSL endpoint) using the following syntax: !DH:!ADH:!DHE

Understanding how local private keys are stored
When you add private keys, Foglight APM Appliances encrypt the key files and save them in hidden files on the appliance. The appliance then implements extensive hardening and security measures, ensuring that your private keys cannot be compromised. Passphrases are not saved.
Exporting local private keys
When exporting the private key from your web server, make sure to select the Yes, Export the private key option. Depending on the web server, the private key is not always included in an export by default. You will need to specify a passphrase for use with the encrypted key file. For more information, see Exporting keys using Microsoft Management Console.

Defining local private keys
When adding or editing a local private key, you can set the following options.
 
Table 24. Defining local private keys
Option
Setting the Option
Key Name
Specify a unique name for the private key.
Choose File
Navigate to and select the encrypted private key file.
Passphrase
Type the passphrase used to encrypt the private key during the export process.
Example
Figure 38. Add Private Key dialog box
Troubleshooting local private keys
When adding a private key, you may see the following message:
The key file you supplied is invalid. Possible reasons are: 1) incorrect password, 2) the file does not contain a private key, 3) the file was exported with strong encryption, or 4) the file is in an unrecognized format.
Due to the nature of SSL, it is impossible to determine precisely why your key may be invalid, but you can try exporting the key again, making sure to select the following options:
•
Select a supported encoding format: PKCS, PEM, or DER.
•
Select the Export Private Key (or similar) option. Depending on the web server, the private key is not always included in an export by default.

Managing HSM private keys

An HSM is an appliance that stores and manages private keys. When integrated with an HSM appliance, Foglight can use the keys within the HSM server to decrypt HTTPS traffic, without having to store the keys locally. Before you can define HSM private keys, you need to complete the steps in Integrating with SafeNet Hardware Security Modules.
Supported HSMs
Foglight currently supports SafeNet Luna SA HSM appliances.
Defining HSM private keys
When adding or editing an HSM private key, you can set the following options.
 
Table 25. Defining HSM private keys
Option
Setting the Option
Partition
Select the HSM partition that contains the key you want to add.
Enter Password
Click Enter Password and type the password for the partition.
Key Name
Select the key.
