Config Series: IPSec Site to Site VPN using Crypto Maps
 
34:11
Site-to-site VPN is one of the VPN options to create a secure transmission of data (data,voice, video) between two branch sites. This is done over public internet, advantage of this solution is it provides as a cheap alternative than paying an MPLS network. Dis-advanatage, not flexible in terms of management, n+1 additional sites would require their own tunnel. Prep Work 1. License, capability of the router to perform an IPsec VPN 2. WAN IPs 3.

IPsec Overview: A secure network starts with a strong security policy that defines the freedom of access to information and dictates the deployment of security in the network. Cisco Systems offers many technology solutions for building a custom security solution for Internet, extranet, intranet, and remote access networks. These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

These scalable solutions seamlessly interoperate to deploy enterprise-wide network security. Cisco System's IPsec delivers a key technology component for providing a total security solution. Cisco's IPsec offering provides privacy, integrity, and authenticity for transmitting sensitive information over the Internet. IPsec provides secure tunnels between two peers, such as two routers. You define which packets are considered sensitive and should be sent through these secure tunnels, and you define the parameters which should be used to protect these sensitive packets, by specifying characteristics of these tunnels. Then, when the IPsec peer sees such a sensitive packet, it sets up the appropriate secure tunnel and sends the packet through the tunnel to the remote peer. More accurately, these tunnels are sets of security associations (SAs) that are established between two IPsec peers. The security associations define which protocols and algorithms should be applied to sensitive packets, and also specify the keying material to be used by the two peers. Security associations are unidirectional and are established per security protocol (AH or ESP). With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. The access lists used for IPsec only determine which traffic should be protected by IPsec, not which traffic should be blocked or permitted through the interface. Separate access lists define blocking and permitting at the interface. A crypto map set can contain multiple entries, each with a different access list. The crypto map entries are searched in order—the router attempts to match the packet to the access list specified in that entry. It is good practice to place the most important crypto map entries at the top of the list. When a packet matches a permit entry in a particular access list, and the corresponding crypto map entry is tagged as cisco, then CET is triggered, and connections are established if necessary. If the crypto map entry is tagged as ipsec-isakmp, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, IPsec uses the Internet Key Exchange protocol (IKE) to negotiate with the remote peer to set up the necessary IPsec security associations on behalf of the data flow. The negotiation uses information specified in the crypto map entry as well as the data flow information from the specific access list entry. If the crypto map entry is tagged as ipsec-manual, IPsec is triggered. If no security association exists that IPsec can use to protect this traffic to the peer, the traffic is dropped. In this case, the security associations are installed via the configuration, without the intervention of IKE. If the security associations did not exist, IPsec did not have all of the necessary pieces configured. Once established, the set of security associations (outbound, to the peer) is then applied to the triggering packet as well as to subsequent applicable packets as those packets exit the router. Applicable packets are packets that match the same access list criteria that the original packet matched. For example, all applicable packets could be encrypted before being forwarded to the remote peer. The corresponding inbound security associations are used when processing the incoming traffic from that peer. If IKE is used to establish the security associations, the security associations will have lifetimes set so that they periodically expire and require renegotiation, thus providing an additional level of security. Multiple IPsec tunnels can exist between two peers to secure different data streams, with each tunnel using a separate set of security associations. For example, some data streams might be just authenticated while other data streams must both be encrypted and authenticated.

UMUC - CMIT 454 - CCNA Security - Spring 2018 - PT 8.4.1.2 Site-to-Site IPSec VPN - Week #6
 
01:29:51
In this comprehensive 'techtorial' on configuring Site-to-Site IPSec VPNs on Cisco routers with crypto maps we dive into how to secure our data communications. We start with a brief introduction to setting up Site-to-Site VPNs with crypto maps, talk about the use of GRE to support multicast/broadcast for routing protocols, and then discuss the current implementation of point-to-point VPNs using Static Virtual Tunnel Interfaces (SVTI). We go over the semantics of the IKE and ISAKMP Phase 1 and 2 settings, transform sets, tunnel mode vs. transport mode, and end things with a brief discussion of DMVPN and how it fits into the overall architecture of data security. This is all done through the lens of Cisco Networking Academy's CCNA Security v2.0 Packet Tracer activity 8.4.1.2 Enjoy!!!

In the last video, I presented a scenario in which Virtual Routing and Forwarding (VRF) was used to partition a single router into 2 virtual routers. I showed you how to configure the VRFs, and in this one, I will go through the configuration of the IPsec portion of that same scenario The typical use case for this is an ISP that provides VPN service to multiple enterprise customers on the same box, the users and branches connect using internet for the encrypted traffic.

GRE Encryption with IPSec | VPN Tunnels Part 2
 
09:20
GRE Encryption with IPSec | VPN Tunnels Part 2 GRE tunnels do not have any native encryption! Fortunately, you can add IPSec encryption in transport mode to your tunnel. First, we’ll have a quick look at how IPSec works. IPSec uses two security tunnels (called phase-1 and phase-2) for authentication, cipher and hash proposal, and session key exchange. Some of the protocols used in this process include ESP (Encapsulating Security Payload), IKE (Internet Key Exchange), ISAKMP, AH (Authentication Header), and the Diffie-Hellman algorithm. Once both sides agree on how these protocols will work, they will have built an SA (Security Association) If you have NAT in your network, IPSec can detect and work around it with NAT-T Try it yourself in the lab! https://networkdirection.net/labsandquizzes/labs/lab-gre-tunnels/ Part 1: How GRE Works - See the encapsulation process, as a packet moves from one side of the network to another Part 2: GRE Encryption with IPSec - GRE is not encrypted by default! See the basics of IPSec, and how we can use it with GRE tunnels Part 3: Improving GRE Stability - There are a few pitfalls to watch out for, including recursive routing. See some of the best practices that you can apply to make your tunnel stable For more information, have a look at https://networkdirection.net/Advanced+GRE This video is useful for Cisco #CCNA and #CCNP certifications 🌏 https://www.youtube.com/c/networkdirection 🌏 https://twitter.com/NetwrkDirection 🌏 https://www.patreon.com/NetworkDirection 🌏 https://www.facebook.com/networkdirection 🌏 https://www.networkdirection.net

Improving GRE stability | VPN Tunnels Part 3
 
07:43
Improving GRE stability | VPN Tunnels Part 3 Once you’ve built your GRE tunnel, you need to make sure it is stable. One of the potential issues that you may face is called Recursive Routing. This can cause your tunnel to flap repeatedly. Recursive Routing occurs when underlay routes are incorrectly advertised into the overlay. This can be worse when little attention is paid to LPM (Longest Prefix Match), the route metric, and the administrative distance. Another concern is the stateless nature of the tunnel. This can result in traffic being blackholed. We can use keepalives (heartbeats), as well as tuning the source and destination interfaces, in order to resolve this issue. There is a catch though. Keepalives do not work with route-based IPSec encryption. Neither does BFD for that matter! Some valid work arounds include using crypto-maps (policy-based encryption), using routing protocols, or using IP SLA with an EEM script. Part 1: How GRE Works - See the encapsulation process, as a packet moves from one side of the network to another Part 2: GRE Encryption with IPSec - GRE is not encrypted by default! See the basics of IPSec, and how we can use it with GRE tunnels Part 3: Improving GRE Stability - There are a few pitfalls to watch out for, including recursive routing. See some of the best practices that you can apply to make your tunnel stable For more information, have a look at https://networkdirection.net/Advanced+GRE Anatomy of GRE Tunnels (by ‘Sarah’): https://learningnetwork.cisco.com/blogs/vip-perspectives/2017/03/14/anatomy-of-gre-tunnels How to Detect IPSec GRE Tunnel Status: https://learningnetwork.cisco.com/message/590257#590257 This video is useful for Cisco #CCNA and #CCNP certifications 🌏 https://www.youtube.com/c/networkdirection 🌏 https://twitter.com/NetwrkDirection 🌏 https://www.patreon.com/NetworkDirection 🌏 https://www.facebook.com/networkdirection 🌏 https://www.networkdirection.net 🌏 https://www.patreon.com/NetworkDirection
