What is Cisco AnyConnect Secure Mobility?
The Cisco AnyConnect Secure Mobility client provides secure SSL or IPsec (IKEv2) connections to the Firepower Threat Defense device for remote users with full VPN profiling to corporate resources. Without a previously-installed client, remote users can enter the IP address of an interface configured to accept clientless VPN connections in their browser to download and install the AnyConnect client. The Firepower Threat Defense device downloads the client that matches the operating system of the remote computer. After downloading, the client installs and establishes a secure connection. In case of a previously installed client, when the user authenticates, the Firepower Threat Defense device, examines the version of the client, and upgrades the client if necessary.

What is a hub and spoke VPN?
In a Hub and Spoke VPN topology, a central endpoint (hub node) connects with multiple remote endpoints (spoke nodes). Each connection between the hub node and an individual spoke endpoint is a separate VPN tunnel. The hosts behind any of the spoke nodes can communicate with each other through the hub node.
How does a VPN work point to point?
In a point-to-point VPN topology, two endpoints communicate directly with each other. You configure the two endpoints as peer devices, and either device can start the secured connection.
How Secure Should a VPN Connection Be?
Because a VPN tunnel typically traverses a public network, most likely the Internet, you need to encrypt the connection to protect the traffic. You define the encryption and other security techniques to apply using IKE polices and IPsec proposals.
What is a CA in VPN?
When you use Digital Certificates as the authentication method for VPN connections, peers are configured to obtain digital certificates from a Certificate Authority (CA). CAs are trusted authorities that “sign” certificates to verify their authenticity, thereby guaranteeing the identity of the device or user.
Why use PKI in VPN?
Using a PKI improves the manageability and scalability of your VPN since you do not have to configure pre-shared keys between all the encrypting devices. Instead, you individually enroll each participating device with a CA server, which is explicitly trusted to validate identities and create an identity certificate for the device. When this has been accomplished, each participating peer sends their identity certificate to the other peer to validate their identities and establish encrypted sessions with the public keys contained in the certificates. See Certificate Enrollment Objects for details on enrolling FTD devices.
Can FTD devices pass through access control?
On a FTD device, by default no traffic is allowed to pass through access-control without explicit permission. VPN tunnel traffic as well, is not relayed to the endpoints until it has passed through Snort. Incoming tunnel packets are decrypted before being sent to the Snort process. Snort processes outgoing packets before encryption.
