IPSec provides flexible building blocks that can support a variety of configurations. Because an IPSec Security Association can exist between any two IP entities, it can protect a segment of the path or the entire path. The main advantage of using IPSec for data encryption and authentication is that IPSec is implemented at the IP layer.

They include the following: Handling man in the Apr 15, 2019 · IPsec VPNs give users the ability to do whatever they can normally do while sitting in the main office from wherever they are. Don’t forget that even a user on an IPsec or SSL VPN with ironclad encryption is still vulnerable to other security threats. Email phishing or phone-based social engineering attacks can strike a secure system at any time. Sep 04, 2018 · IPSec has two modes of encryption called “Transport” and “Tunnel”. Transport mode is equivalent to End-to-End in that it does NOT protect the IP headers, just the data. Tunnel mode is equivalent to Link encryption and protects (encrypts) the data and the IP header information.

Azure VPN gateways now support per-connection, custom IPsec/IKE policy. For a Site-to-Site or VNet-to-VNet connection, you can choose a specific combination of cryptographic algorithms for IPsec and IKE with the desired key strength, as shown in the following example: You can create an IPsec/IKE policy and apply to a new or existing connection.

The IPSec tunnel configuration allows you to authenticate and/or encrypt the data (IP packet) as it traverses the tunnel. If you are setting up the firewall to work with a peer that supports policy-based VPN, you must define Proxy IDs. Devices that support policy-based VPN use specific security rules/policies or access-lists (source addresses How IPsec works, why we need it, and its biggest drawbacks
