2 VPN Overview Lesson 10a April 2004 etoken Certification Course
3 Virtual Private Network A Virtual Private Network (VPN) is a private data network that uses the public telecommunication infrastructure. VPNs accomplish this by allowing the user to tunnel through the Internet or another public network in a manner that provides the same security and features formerly available only in private networks (leased lines) but cheaper. Privacy is maintained through the use of a tunneling protocol and security procedures Communication across the VPN is encrypted.
4 How Safe is a Password? One-factor authentication memorized password only seriously weakens VPN system security Typed passwords can be easily copied or hacked Users often select short, easy to remember passwords Passwords seldom changed, often written down and left in easily accessible places Users have difficulty remembering several passwords for different applications and so, use the same password for all their access needs
5 Using Digital Certificates for Authentication Digital certificates provide a reliable method for verifying the identity of a user. The client presents client certificate to the dial-in server providing strong user authentication via a challenge responese mechanism. The server presents a server certificate to the client provides assurance that the user has reached the server that he/she expected. A chain of thrusted authorities verifies the validity of the certificates. The user s certificate can be stored on the client machine or in an external smartcard. The certificate can be accessed after the user s identification (two factor authentication).
6 VPN and etoken Using IPSEC Certificates Generated and Stored On etoken Generate an IPSEC certificate with on-board 1024-bit keys created in the etoken keys are secure Two factor authentication in front of the gateway using a PKI certificate. The gateway verifies the authentication in front of the CA After secure authentication, a VPN connection is established using the IPSEC/IKE encryption method Simple integration, the user installs etoken PKI Client, no further configuration is necessary

11 Tunneling Protocols The tunneling protocol encapsulates the packet in an additional header. The additional header provides routing information so that the encapsulated packet can pass the internetwork. IP Security (IPSec) Tunnel Mode allows IP packets to be encrypted and then encapsulated in IP header to be sent across a corporate IP or public IP network. Layer 2 Tunneling Protocol (L2TP) Allows traffic to be encrypted and then sent through a medium that supports Point-to-Point Datagram delivery, such as: IP, X.25, Frame relay, ATM.
12 How VPNs work - Tunnel Layer 3 - Network layer IPSec Used for site to site and remote user to site communications Can authenticate and encrypt data 7-Layer OSI Model Application Layer Presentation Layer Session Layer Layer 2 - Data link layer L2TP (EAP-TLS) Used for remote user to site communications L2TP can authenticate only Transport Layer Network Layer Data Link Layer Physical Layer
13 IPSec Architecture IPSec is defined by the following sets of specifications: Security Associations (SA) Internet Key Exchange (IKE, ISAKMP,OAKLY) Authentication header protocol (AH) Encapsulated security protocol (ESP) Protocol modes. (Transport and tunnel mode) Encryption algorithms
14 IKE Negotiation Two Phases Phase 1 Negotiate two way SAs Uses certificates or pre-shared secrets Main mode or aggressive mode Phase 2 Negotiate IPSEC (AH, ESP, Tunnel, Transport) Phase 2 always uses quick mode because we are already authenticated
15 Internet Key Exchange (IKE) Authenticates peers Pre-shared keys Public key cryptography Digital signatures Negotiates policy to protect communication Key exchange Diffie-Hellman IKE 1st IPSec Next
16 IKE In IP security, there are two types of SAs: IKE SA : used for securing key negotiations. IPSEC SA : used for securing IP data. When two IP entities wish to secure IP data between them, the following will occur: Negotiate IKE SA. Use IKE SA to negotiate IPSEC SA. Use IPSEC SA to encrypt IP data. The IKE SA is long term. It will typically be used to secure many IPSEC SA negotiations.
17 Key Management
18 IKE Basic concept in IKE: Security Association (SA). An SA contains all information necessary for two entities to exchange secured messages. Each SA has an identifier, sometimes called an SPI. Example SA: SPI: Encryption algorithm: DES HMAC algorithm: MD5 Encryption key: 0x65f3dde HMAC key: 0xa3b443d9 Expiry: 15:06:09 13Oct98
19 IKE The negotiation of IKE SAs is called Phase 1. Phase 1 is authenticated using either PKI or pre-shared secrets. There are two types of Phase 1 negotiations: Main Mode and Aggressive Mode. Aggressive Mode is more efficient (shorter negotiation), but does not provide identity protection. Negotiating IPSEC SAs is called Phase 2. There is only one type of Phase 2 negotiation called Quick Mode.
20 IKE Phase 1: First Message Pair Phase 1 Main Mode consists of three pairs of messages. Remember: goal is to establish an IKE SA First pair: Negotiation of parameters for the IKE SA: algorithms, authentication type, expiry. Alice We can do 3DES and SHA1, or DES and MD5 Let s do 3DES and SHA1 Bob ISAKMP Policy Tunnel
21 IKE Phase 1: Second Message Pair Second pair: Exchange of cryptographic data. Goal is to establish a shared secret between two entities: Alice Here s a DH public key, and some random data Here s a DH public key, and some random data Alice and Bob both compute a shared secret which is a function of the DH keys and the random data. Bob Note: the DH key is used only for this exchange, and then thrown away.
22 Diffie Hellman Internet
23 IKE Phase 1 Some notes before the third pair of messages: Alice and Bob now have a shared secret, and they can use it to encrypt the third pair of messages. First and second pairs do not provide any authentication. Alice and Bob could be masquerading, or Eve could be attacking using the man-in-the-middle technique. Furthermore, Alice and Bob do not know who they are negotiating with. All they know is an IP address from which the messages are arriving.
24 IKE Phase 1: Third Message Pair Third pair of messages is encrypted. The goal is to exchange identities, prove the identities, and retroactively authenticate all the previous messages. The authentication can be based on either pre-shared secrets, or on PKI. Example: I m alice@wonderland.com. Here s an HMAC over all the data we exchanged, using our pre-shared secret. Alice I m Here s an HMAC over all the data we exchanged, using our pre-shared secret.. Bob Result of negotiation is a single, bi-directional IKE SA.
25 IKE Phase 2 Phase 2 is always secured by an IKE SA. The IKE SA provides secrecy, authentication, and data integrity. Remember: The goal is to establish an IPSEC SA. Three messages in Phase 2: Message 1: Suggestion of parameters, and identities for whom we re negotiating. Message 2: Choice of parameters, and HMAC signature on first message. Message 3: HMAC signature on previous messages. HMAC signatures use a key from the IKE SA.
26 IKE Phase 2 Example Phase 2 (simplified) exchange: Let s do either ESP DES/MD5, or AH SHA1. I m negotiating on behalf of subnets and Here s some random data. Alice Let s use AH SHA1. Here s an HMAC of the previous message using our IKE SA HMAC key. Here s some random data Bob Here s an HMAC of the previous messages using our IKE SA HMAC key.
27 IKE Phase 2 Remarks: The keys in the resulting IPSEC SA are a function of the IKE SA key and the random data. The result of the negotiation are two uni-directional IPSEC SAs, each with a distinct SPI (SPIs are also part of the negotiation). The SAs can only be used to encrypt IPSEC traffic between the negotiated identities. Identity types are IP addresses, IP ranges, IP subnets.
28 IPSec Modes (Transport and Tunnel) Transport Mode: Used for Peer to Peer communication security Data is encrypted Tunnel Mode: Used for site-to-site communication security Entire packet is encrypted.
29 IPSec Overview: Headers Encapsulated Security Payload All Data-Encrypted Router IP HDR AH Data Router Authentication Header Two types: Encapsulated Security Payload (ESP) and Authentication Header (AH) Data integrity no modification of data in transit Origin authentication identifies where data originated AH does not provide confidentiality, industry moving toward ESP which does
30 AH (Authentication Header) IP Protocol 51 Provides authentication of packets Does not encrypt the payload Transport Mode IP Hdr AH TCP/UDP Data Tunnel Mode New IP Hdr AH Org. IP Hdr TCP/UDP Data
31 ESP (Encapsulating Security Payload) IP Protocol 50 Encrypts the payload Provides encryption and authentication Transport Mode IP Hdr IP Hdr AH ESP TCP/UDP Data Tunnel Mode New IP Hdr AH ESP Org. IP Hdr TCP/UDP Data
32 Basic difference between AH and ESP
33 Layer 2 Tunneling Protocol Combines and extends PPTP and L2F (Cisco supported protocol) Does not include packet authentication, data integrity, or key management Must be combined with IPSec for enterprise-level security Remote L2TP Client Corporate Network L2TP Server Internet ISP L2TP Concentrator
34 L2TP over IPSEC
35 L2TP over IPSEC
36 EAP-TLS Developed by Microsoft Provides strong mutual authentication, credential security, and dynamic keys Requires distribution of certificates to all users as well as RADIUS servers A certificate management infrastructure is required (PKI)
37 EAP Protocol-overview 802.1X is a transport mechanism. The actual authentication takes place in the EAP-protocol on top of 802.1X. MD5 TLS TTLS PEAP MS-CHAPv2 EAP 802.1X PPP
38 Tunneling Protocols For a tunnel to be established, both the tunnel client and the tunnel server have to run the same tunneling protocol. The tunnel client or server uses a tunnel transfer protocol to prepare data for transfer. EAP Extensible Authentication Protocol Extension to PPP that allows the validation of PPP connection through authentication mechanisms. EAP allows the dynamic addition of authentication plug-in modules, at the client and the server. This enables vendors to supply a new authentication scheme at any time. For example: using public key certificates for user authentication.
39 EAP over 802.1x Extensible Authentication Protocol (RFC 2284) provides an architecture in which several authentication mechanisms can be used EAP-MD5 Username/Password (not safe) EAP-TLS PKI (certificates), strong authentication MS-CHAPv2 Microsoft Username/Password (not safe)

41 etoken for Microsoft VPN Lesson 10d April 2004 etoken Certification Course
42 Microsoft VPN Windows 2000 remote access provides two different types of remote access connectivity: Dial-up remote access (RAS) Virtual private network (VPN) remote access
43 Dial-up remote access To gain access to the network with dial-up remote access, a remote access client uses the public telephone network to create a physical connection to a port on a remote access server that sits on the edge of the private network. This is typically done by using a modem or ISDN adapter to dial into your remote access server
44 Authenticating Dial-up remote access users Secure Mutual authentication is obtained by authenticating both ends of the connection through the encrypted exchange of user credentials. This is possible with the PPP remote access protocol using the EAP-Transport Level Security (EAP-TLS). During mutual authentication, the remote access client authenticates itself to the remote access server, and then the remote access server authenticates itself to the remote access client.
45 RAS Data Encryption Windows 2000 remote access clients and remote access servers support the Microsoft Point-to-Point Encryption Protocol (MPPE). In order to use MPPE for Data Encryption The authentication protocol must be either EAP-TLS or MS-CHAP MPPE uses the RC4 stream cipher and either 40-bit, 56-bit, or 128-bit secret keys. MPPE keys are generated from the EAP-TLS user authentication process
46 Virtual private network (VPN) remote access A VPN can provide secure remote access through the Internet, rather than through direct dial-up connections. A VPN client uses an IP internetwork to create an encrypted, virtual, point-to-point connection with a VPN gateway that exists on the edge of the private network. This is typically done by connecting to the Internet first, and then creating the VPN connection..
47 Windows 2000 supports two types of VPN : Point-to-Point Tunneling Protocol (PPTP) Layer 2 Tunneling Protocol over IP Security (L2TP/IPSec).
48 PPTP vs. L2TP PPTP requires that the transit internetwork be an IP internetwork. L2TP requires only that the tunnel media provide packet-oriented point-to-point connectivity- NO NAT!!! L2TP provides tunnel authentication, while PPTP does not. PPTP uses PPP encryption and L2TP does not.
49 Authenticating VPN remote access users Secure Mutual authentication is obtained by authenticating both ends of the connection through the encrypted exchange of user credentials. This is possible with the PPP remote access protocol using the EAP- Transport Level Security (EAP-TLS). Machine authentication is performed as well only when using L2TP over IPSEC
50 EAP-TLS The Extensible Authentication Protocol (EAP) can be used to provide an added layer of security to VPN technologies such as PPTP and L2TP. EAP allows this functionality through Certificate Authority (CA) and Smart Card technologies, which provide mutual authentication of client and server. The server must be configured to accept EAP authentication as a valid authentication method and have a user certificate (X.509). The client must be configured to use EAP, and either have a Smart Card (with a Smart Card certificate installed).
51 VPN Data Encryption for PPTP Windows 2000 remote access clients and remote access servers support the Microsoft Point-to-Point Encryption Protocol (MPPE). In order to use MPPE for Data Encryption The authentication protocol must be either EAP-TLS or MS- CHAP MPPE uses the RC4 stream cipher and either 40-bit, 56-bit, or 128-bit secret keys. MPPE keys are generated from the EAP-TLS user authentication process
52 VPN Data Encryption for L2TP Use IPSec to encrypt the data all the way from the sending computer to the destination computer. This is called end-to-end encryption.

103 Troubleshooting
104 Event Logging The Windows 2000 Router performs extensive error logging in the system event log. Four levels of logging are available. Take specific steps if an OSPF router is unable to establish an adjacency on an interface. The level of event logging can be set from various places with the Routing and Remote Access snap-in. Logging consumes system resources and should be used sparingly.
105 Tracing RRAS has an extensive tracing capability that you can use to troubleshoot complex network problems. Tracing records internal component variables, function calls, and interactions. You can enable tracing for each routing protocol by setting the appropriate registry values. Tracing consumes system resources and should be used sparingly. To enable file tracing for each component, you must set specific values within the registry.
106 Authentication and Accounting Logging RRAS supports the logging of authentication and accounting information for PPP-based connection attempts when Windows authentication or accounting is enabled. The authentication and accounting information is stored in a configurable log file or files. You can configure the type of activity to log and log file settings.
107 Setting up Event Logging Click the Event Logging tab and choose Log the maximum amount of information. This helps with troubleshooting connection problems. You are now finished configuring the properties of the VPN server. Click OK.
108 Basic L2TP/IPSec Troubleshooting in Windows If the Virtual Private Network (VPN) client is behind any network device performing Network Address Translation (NAT), the L2TP session fails because encrypted IPSec Encapsulating Security Payload (ESP) packets become corrupted.
109 Basic L2TP/IPSec Troubleshooting in Windows If a computer certificate is not found, L2TP issues a warning that you do not have a certificate, but it does not know whether the certificate has a properly installed and associated private key for the existing certificate. Internet Key Exchange (IKE) determines this during negotiation. Start the Local Computer Certificates snapin, double-click Certificate, and verify that General indicates "You have a private key that corresponds with this certificate." Also verify that the certificate path is complete, and that the certificate is valid.
110 Basic L2TP/IPSec Troubleshooting in Windows The client must have a machine certificate whose root certificate authority is the same as the certificate on the gateway certificate. The reason for the certificate failure is noted by IKE in the security log event entry.
111 Troubleshooting L2TP/IPsec You can verify whether IPSec is succeeding by running Ipsecmon.exe (as local admin) with options set to refresh at one-second intervals. If you see the IPSec SA appear, it indicates that IPSec succeeded, and you may conclude that L2TP is the source of the problem. Use the netdiag /test:ipsec /v /debug command to see the details of IPSec policy (you cannot see the whole policy if a domain administrator has set policy on your local computer).
112 Troubleshooting L2TP/IPsec IKE may time out during the initial negotiation request if routers in front of the VPN server do not allow UDP port 500 through. It also times out if the VPN server does not have appropriate IPSec policy configured, which usually means that the RRAS server does not have L2TP ports enabled, or that a manual IPSec policy setting is misconfigured. When IKE times out, the audit log shows that peer failed to reply, and that a network capture trace shows ISAKMP UDP packets initiating only from your client. If configured specifically for L2TP, the VPN client responds with the following error message: The security negotiation timed out.
113 Troubleshooting L2TP/IPsec Microsoft Client (Cont ) Error 792 : Security negotiation timeout
114 Troubleshooting L2TP/IPsec Microsoft Client Error 789 : Security layer encountered a processing error From Start > Control Panel > Administrative Tools, double-click on Services and verify that the IPSec Policy agent is running.
115 Troubleshooting L2TP/IPsec Microsoft Client (Cont ) Error 786 : No valid machine certificate This error indicates a problem with the certificate on the local machine. Run mmc and add Certificate/ Computer Account snap-in Navigate going to Console Root -> Certificate (Local Computer) -> Personal -> Certificates and verify that the certificate is valid/ not expired. Make sure that the Trusted Root Certificate under the local computer store contains the root CA certificate
116 Troubleshooting L2TP/IPsec Microsoft Client (Cont ) Enabling Audit Policy for the local PC in the Local Computer Policy snap-in. In the MMC console, From the left pane expend the tree, then navigate to Computer Configuration > Windows Setting > Security Setting > Local Policies and select Audit Policy. From the list of Attributes displayed in the right pane, modify the following: Audit Logon Events, Audit Object Access. For each attribute check, in the Local Policy setting group box, Success, Failure.
117 Troubleshooting L2TP/IPsec Microsoft Client (Cont ) Navigate to Computer Management > System Tools > Event Viewer and check for additional information
118 Troubleshooting L2TP/IPsec Microsoft Client (Cont ) Netdiag utility for network diagnostic (must be installed first) In order to test IPSec parameters, execute the command as follows: netdiag/test:ipsec /v /debug Detailed information can be found at / IP Security Monitor Execute ipsecmon to monitor security connections created by the IPSec policy
