Is DH Group 19 secure?
And according to this document on p. 30 (from the “European Network of Excellence in Cryptology”), the bits of security for the elliptic curve groups are the following: Group 19 = 256-bit EC = 128 bits of security. Group 20 = 384-bit EC = 192 bits of security.
Is Diffie-Hellman Group 14 secure?
diffie-hellman-group14-sha256. This key exchange uses the group14 (a 2048-bit MODP group) along with a SHA-2 (SHA2-256) hash. This represents the smallest Finite Field Cryptography (FFC) Diffie-Hellman (DH) key exchange method considered to be secure.
What is DH group used for?
Diffie-Hellman (DH) groups determine the strength of the key used in the key exchange process. Within a group type (MODP or ECP), higher Diffie-Hellman group numbers are usually more secure.
What DH Group 24?
RFC 5114 Sec 4 states DH Group 24 strength is about equal to a modular key that is 2048-bits long, that is not strong enough to protect 128 or 256-bit AES, so I also mark that as AVOID.
Is DH Group 24 secure?
If you are using encryption or authentication algorithms with a 256-bit key or higher, use Diffie-Hellman group 21. RFC 5114 Sec 4 states DH Group 24 strength is about equal to a modular key that is 2048-bits long, that is not strong enough to protect 128 or 256-bit AES, you should stay away from 24.
What is MODP group?
This document defines new Modular Exponential (MODP) Groups for the Internet Key Exchange (IKE) protocol. It documents the well known and used 1536 bit group 5, and also defines new 2048, 3072, 4096, 6144, and 8192 bit Diffie-Hellman groups numbered starting at 14.
What is Ffdhe?
Vocabulary The terms “DHE” or “FFDHE” are used in this document to refer to the finite-field-based Diffie-Hellman ephemeral key exchange mechanism in TLS.
What is a bovpn virtual interface?
A BOVPN virtual interface defines a BOVPN tunnel that is treated in the configuration like an interface. The Firebox uses the routes table to determine whether to route a packet through the BOVPN virtual interface or through another interface. For configuration examples, see BOVPN Virtual Interface Examples.
Which endpoints are supported by bovpn?
Supported endpoints include cloud-based virtual networks, such as Microsoft Azure, Amazon AWS, and Cisco VTI endpoints. With a BOVPN virtual interface, you can:
What is the MTU value for bovpn virtual interfaces?
For VTI-based virtual interfaces, the MTU is 1500. In Fireware v12.5 or higher, you can specify a custom maximum transmission unit (MTU) value for BOVPN virtual interfaces. The MTU setting is specific to individual BOVPN virtual interfaces and is not a global Firebox setting.
How do I configure dynamic routing for a bovpn virtual interface?
Add static routes for a BOVPN virtual interface. Assign an IP address to the BOVPN virtual interface (required for dynamic routing, and recommended if either endpoint is behind a NAT device). Use a BOVPN virtual IP address in the dynamic routing configuration.
