The most secure is the default. We will configure our own. You can remember this by HAGLE. Hash, Authentication, Group (DH), Lifetime, Encryption. Router(config)#crypto isakmp policy 1 Router(config-isakmp)#hash sha Router(config-isakmp)#authentication pre-share Router(config-isakmp)#group 5 Router(config-isakmp)#lifetime 3600 Router(config-isakmp)#encryption aes 256 We used a pre-shared key for authentication so we need to specify the password for the first phase.

Hence the transform. Router(config)#crypto ipsec transform-set transform_name esp-aes esp-sha-hmac Task 3: Configure ACL to define interesting traffic Even though the tunnel is setup it doesn’t exist yet.

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!!!

IPsec Replay
 
06:08
This tutorial explains how IPsec performs protection against replay attacks. The general idea of a replay attack has been explained by us in an earlier movie; this movie focuses on IPsec. It shows how IPsec uses sequence numbers and a window mechanism to detect such attacks. It also touches the difference between the IPsec window mechanism and that of TCP.

PLNOG15 - G-IKEv2 (Salah Gherdaoui,  Praveena Shanubhogue)
 
30:29
Cisco Group Encrypted Transport VPN (GET VPN) includes a set of features that are necessary to secure IP multicast group traffic or unicast traffic over an enterprise private WAN that originates on or flows through a Cisco device. The GETVPN G-IKEv2 feature implements Internet Key Exchange version 2 (IKEv2) protocol on GETVPN thereby allowing GETVPN to derive the benefits of IKEv2. Some of those advantages are: o Less packets (typically 4 instead of 10) o Dead Peer Detection and Network Address Translation-Traversal o Certificate URLs o Denial of Service Attack Resilience o EAP Support o Multiple Crypto Engines o Suite-B Support o Reliability and State Management (Windowing) http://www.facebook.com/PLNOG http://www.plnog.pl http://www.twitter.com/plnog

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.

IPSec
 
01:05
IPSec Short for IP Security, a set of protocols developed by the IETF to support secure exchange of packets at the IP layer. IPsec has been deployed widely to implement Virtual Private Networks (VPNs). IPsec Encryption Modes IPsec supports two encryption modes: Transport and Tunnel. Transport mode encrypts only the data portion (payload) of each packet, but leaves the header untouched. The more secure Tunnel mode encrypts both the header and the payload. On the receiving side, an IPSec-compliant device decrypts each packet. For IPsec to work, the sending and receiving devices must share a public key. This is accomplished through a protocol known as Internet Security Association and Key Management Protocol/Oakley (ISAKMP/Oakley), which allows the receiver to obtain a public key and authenticate the sender using digital certificates.

Show crypto isakmp sa The following four modes are found in IKE main mode MM_NO_STATE* – ISAKMP SA process has started but has not continued to form (typically due to a connectivity issue with the peer) MM_SA_SETUP* – Both peers agree on ISAKMP SA parameters and will move along the process MM_KEY_EXCH* – Both peers exchange their DH keys and are generating their secret keys. (This state could also mean there is a mis-matched authentication type or PSK, if it does not proceed to the next step) MM_KEY_AUTH* – ISAKMP SA’s have been authenticated in main mode and will proceed to QM_IDLE immediately. The following three modes are found in IKE aggressive mode AG_NO_STATE** – ISAKMP SA process has started but has not continued to form (typically do to a connectivity issue with the peer) AG_INIT_EXCH** – Peers have exchanged their first set of packets in aggressive mode, but have not authenticated yet. AG_AUTH** – ISAKMP SA’s have been authenticated in aggressive mode and will proceed to QM_IDLE immediately. The following mode is found in IKE Quick Mode, phase 2 QM_IDLE*** – The ISAKMP SA is idle and authenticated Here are a few more commands we can issue to get a quick glimpse of the status of any IPSec VPN’s. sh crypto ipsec sa – Now this output can really daunting at first just due to the amount of information that is displayed here but there are a few key things to watch out for. Such as the #pkts encaps/encrypt/decap/decrypt, these numbers tell us how many packets have actually traversed the IPSec tunnel and also verifies we are receiving traffic back from the remote end of the VPN tunnel. This will also tell us the local and remote SPI, transform-set, DH group, & the tunnel mode for IPSec SA. sh crypto session Up-Active – IPSec SA is up/active and transferring data. Up-IDLE – IPSsc SA is up, but there is not data going over the tunnel Up-No-IKE – This occurs when one end of the VPN tunnel terminates the IPSec VPN and the remote end attempts to keep using the original SPI, this can be avoided by issuing crypto isakmp invalid-spi-recovery Down-Negotiating – The tunnel is down but still negotiating parameters to complete the tunnel. Down – The VPN tunnel is down. So using the commands mentioned above you can easily verify whether or not an IPSec tunnel is active, down, or still negotiating. Next up we will look at debugging and troubleshooting IPSec VPNs * – Found in IKE phase I main mode ** – Found in IKE phase I aggressive mode *** – Found in IKE phase II quick mode DE NADA SIRVE MONTAR UNA SONDA SINO SE APLICA EL CORRECTIVO, QUEDARIA CON UP-NO-IKE Otro punto es que es multipoint pero al final son IP´s fijas en ambos extremos remoto y central.

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.
