Netdev 0x12 - IPsec/IKE tutorial/lab
 
02:01:27
If you have ever been intimidated by IPsec or always wondered what IPsec is and/or how IPsec datapath works in the kernel or how IPsec control path works in user space, then this tutorial is for you. Sowmini Varadhan and Paul Wouters guided us through the theory and walked through the steps for setting up IKE/IPsec on VMs on our laptops. A number of other VMs were be made available as targets to connect-to for the different IKE scenarios via Libreswan. These scenarios included some commonly encountered roadblocks that are used to teach IPsec troubleshooting issues. This tutorial/lab was presented at Netdev 0x12 in Montreal on July 11th, 2018.

USENIX Security '18 - The Dangers of Key Reuse: Practical Attacks on IPsec IKE
 
25:59
Dennis Felsch Ruhr-University Bochum Abstract: IPsec enables cryptographic protection of IP packets. It is commonly used to build VPNs (Virtual Private Networks). For key establishment, the IKE (Internet Key Exchange) protocol is used. IKE exists in two versions, each with different modes, different phases, several authentication methods, and configuration options. In this paper, we show that reusing a key pair across different versions and modes of IKE can lead to cross-protocol authentication bypasses, enabling the impersonation of a victim host or network by attackers. We exploit a Bleichenbacher oracle in an IKEv1 mode, where RSA encrypted nonces are used for authentication. Using this exploit, we break these RSA encryption based modes, and in addition break RSA signature based authentication in both IKEv1 and IKEv2. Additionally, we describe an offline dictionary attack against the PSK (Pre-Shared Key) based IKE modes, thus covering all available authentication mechanisms of IKE. We found Bleichenbacher oracles in the IKEv1 implementations of Cisco (CVE-2018-0131), Huawei (CVE-2017-17305), Clavister (CVE-2018-8753), and ZyXEL (CVE-2018-9129). All vendors published fixes or removed the particular authentication method from their devices’ firmwares in response to our reports.

Internet Key Exchange
 
12:26
In computing, Internet Key Exchange (IKE or IKEv2) is the protocol used to set up a security association (SA) in the IPsec protocol suite. IKE builds upon the Oakley protocol and ISAKMP. IKE uses X.509 certificates for authentication - either pre-shared or distributed using DNS (preferably with DNSSEC) and a Diffie–Hellman key exchange - to set up a shared session secret from which cryptographic keys are derived. In addition, a security policy for every peer which will connect must be manually maintained. This video is targeted to blind users.

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.

ISAKMP is a protocol defined by RFC 2408 for establishing Security Associations and cryptographic keys in an Internet environment. ISAKMP only provides a framework for authentication and key exchange and is designed to be key exchange independent; protocols such as Internet Key Exchange and Kerberized Internet Negotiation of Keys provide authenticated keying material for use with ISAKMP. For example: IKE describes a protocol using part of Oakley and part of SKEME in conjunction with ISAKMP to obtain authenticated keying material for use with ISAKMP, and for other security associations such as AH and ESP for the IETF IPsec DOI This video is targeted to blind users.

Critical VPN key exchange flaw exposes Cisco security appliances to remote hacking
 
03:11
Cisco Systems patched a critical vulnerability that could allow remote attackers to take over Cisco Adaptive Security Appliance (ASA) firewalls configured as virtual private network servers by simply sending malformed network packets to them. For devices that are designed to protect private networks from Internet attacks, this is as bad as it gets. That's why Cisco rated the vulnerability with the maximum score of 10 in the Common Vulnerability Scoring System. The flaw is located in the Cisco ASA code that handles the Internet Key Exchange version 1 (IKEv1) and IKE version 2 (IKEv2) protocols. More precisely, it stems from a buffer overflow condition in the function that processes fragmented IKE payloads. "An attacker could exploit this vulnerability by sending crafted UDP packets to the affected system," Cisco said in an advisory. "An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system." IKE is used as a key exchange mechanism in IPsec-based virtual private networks (VPNs). As such, the Cisco ASA devices are only vulnerable if they are configured to act as termination points for LAN-to-LAN IPsec VPN, remote access VPN using the IPsec VPN client, Layer 2 Tunneling Protocol (L2TP)-over-IPsec VPN connections and IKEv2 AnyConnect. Cisco ASA products are frequently configured for VPN. Their strength is that they can provide IP routing, firewall, network antivirus, intrusion prevention and VPN functionality in a single device. According to Cisco the following products are vulnerable: Cisco ASA 5500 Series Adaptive Security Appliances, Cisco ASA 5500-X Series Next-Generation Firewalls, Cisco ASA Services Module for Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers, Cisco ASA 1000V Cloud Firewall, Cisco Adaptive Security Virtual Appliance (ASAv), Cisco Firepower 9300 ASA Security Module and Cisco ISA 3000 Industrial Security Appliance. The Cisco advisory contains a list with the fixed Cisco ASA software versions for different release branches. Users are advised to update as soon as possible. The Internet Storm Center at the SANS Technology Institute has reported seeing a large increase in Internet probes on UDP port 500, which is the most likely port number for exploiting this vulnerability.
