  • Chapter 14 - Network security: Firewalls and VPNs. In this chapter, we look at four issues of security: privacy, authentication, integrity, and nonrepudiation. We show how the first can be achieved through secret-key or private-key encryption. We discuss a concept called digital signature that satisfies the three other conditions. We talk about how security is implemented in the Internet.

  • IPSec—IP Security Protocol. IPSec is a framework of open standards that provides data confidentiality, data integrity, and data authentication between participating peers. IPSec provides these security services at the IP layer; it uses IKE to handle negotiation of protocols and algorithms based on local policy and to generate the encryption and authentication keys to be used by IPSec. IPSec can be used to protect one or more data flows between a pair of hosts, between a pair of security gateways, or between a security gateway and a host....

  • In the most commonly used scenario, IPsec allows an encrypted tunnel to be created between two private networks. It also allows for authenticating the two ends of the tunnel. However, the IPsec protocol allows only for the encapsulation and encryption of IP data (unlike GRE, which can tunnel but not encrypt non-IP traffic), so to create a tunnel for non- IP-based traffic, IPsec must be used in conjunction with a protocol such as GRE, which allows for the tunneling of non-IP protocols.
