2 Basic Security Requirements and Techniques Confidentiality The property that stored or transmitted information cannot be read or altered by an unauthorized party Integrity The property that any alteration of transmitted or stored information can be detected
3 Current Solutions Internet adoption grew Applications were designed and operated ad hoc security solutions Provides semi-trusted and semi-secure Internet access Don t address fundamental issues Mostly concerned with fighting symptoms
4 Current Solutions Packet Filters and Firewalls Filters traffic based on predefined rules IP address port numbers virus patterns May determine unusual behavior
5 - example
6 The IPSEC framework A formally defined standard (RFC 2401) Contains 6 distinct elements Description of security requirements and mechanisms on the network layer Security element for encryption (RFC 2406) Security element for authentication (RFC 2402) Concrete cryptographic algorithms for encryption and authentication Definition of Security policy and Security associations between partners IPSEC key management ISAKMP - RFC Internet Security Association and Key Management Protocol
7 Source: IPv6 Essentials, O Reilly Press, 2002 Security in IPv6 The IPSEC framework
8 Authentication in IPv6 Extension Header type 51 provides integrity and authentication for end to end data
9 Authentication in IPv6 Next Header Length of Payload in x32 bits Reserved SPI - Indicates which checksum algorithm has been used Sequence Number - Prevents replay attacks Not to exceed 232 to prevent replay. Re-negotiation should occur It is know that packets may arrive out of order Authentication Data - variable length A cryptographically secure checksum over the payload and possibly other fields
10 Authentication in IPv6 Cryptographical checksum is also known as a message digest or hash. Uses rules IP Header, version, class, and flow label are excluded from the computation. Hop Limit is assumed to contain zero All Extension Headers that change en-route are computed as a sequence of zero If Routing Extension Header is present the IPv6 destination address is set to the final destination IPv6 implementations MUST support Keyed message digest No. 5 (MD5) requires key considered theoretically breakable Secure Hash Algorithm No. 1 (SHA-1)
11 Authentication in IPv6 Payload Authentication Transport mode authenticates all end to end payload plus selected headers (described previously) Payload Length Next Header Extension headers (not listed previously) Upper layer headers and data Some IP header fields are not protected Will not work with NAT environment
12 Authentication in IPv6 Header and Payload Authentication Accomplished by creating a tunnel between 2 gateways Gateway may be a router May be a VPN implementation Wraps the original packet in a new packet Applies checksum to entire packet
13 Encryption in IPv6 Extension Header type 50 provides integrity and confidentiality
14 Encryption in IPv6 SPI - Indicates which encryption algorithm has been used Sequence Number - Prevents replay attacks Not to exceed 232 to prevent replay. Re-negotiation should occur It is know that packets may arrive out of order Encryption Parameters - variable length Depends on the encryption algorithm used Encrypted Data
15 Encryption in IPv6 Trailer Contains Optional authentication information to protect the encrypted data and the sequence number Padding (for 64 bit alignment) Next Header value (in the encrypted packet) IPv6 specification contains one encryption algorithm that must be supported by every implementation DES-CBC (Data Encryption Standard in Cipher Block Chaining Mode) Other stronger algorithms may be negotiated using corresponding SA and SPI Government export controls
16 Encryption in IPv6 Payload encryption Transport mode encrypts all end to end extension headers and payload Extension headers must not be looked at in path
17 Encryption in IPv6 Header and Payload encryption Accomplished by creating a tunnel between 2 gateways Gateway may be a router May be a VPN implementation Wraps the original packet in a new packet Applies checksum to entire packet
18 Encryption in IPv6 Combining Authentication and Encryption It was originally intended to use both But increased IPv6 packet size was not good Decided to included AH functionality in ESP
19 IPSEC may solve many issues on the Internet FTP, Telnet, DNS, and SNMP However other issues exist IPSEC tunnels break through firewalls or NAT Tunneled IPSEC traffic may contain malicious data QOS doesn t work in IPSEC Mobility issues Dynamic IP addresses cause IPSEC to fail
20 IPv6 deployment slowed due to IPv4 workarounds NAT and CIDR SSL SSH S/MIME, PGP IPSEC deployment issues lack of public key infrastructure lack of vendor/ipv6 adoption
