Large Internet Service Providers (ISPs) increasingly believe that "deep packet inspection" is required to protect their internal infrastructure, as well as their customers, from malicious hacking and computer crime.

In order to decide what protection is to be provided for an outgoing packet, IPsec uses the Security Parameter Index (SPI), an index to the security association database (SADB), along with the destination address in a packet header, which together uniquely identifies a security association for that packet. A similar procedure is performed for ...

Security service is a service, provided by a layer of communicating open systems, which ensures adequate security of the systems or of data transfers [1] as defined by ITU-T X.800 Recommendation. X.800 and ISO 7498-2 (Information processing systems – Open systems interconnection – Basic Reference Model – Part 2: Security architecture) [ 2 ...
A common example is an ISP point of presence, the local access point that allows users to connect to the Internet with their Internet service provider (ISP). [1] A PoP typically houses servers , routers , network switches , multiplexers , and other network interface equipment, and is typically located in a data center .
A computer or other device accessing the Internet would either be connected directly to a modem that communicates with an Internet service provider (ISP) or the modem's Internet connection would be shared via a LAN which provides access in a limited area such as a home, school, computer laboratory, or office building.
