Q: Are pings forwarded by routers? A: Yes! This is why you can ping devices all over the Internet. Q: Do all devices forward or respond to pings? A: No, this is up to the network administrator of the device. Devices, including routers, can be configured not to reply to pings (ICMP echo requests). This is why you may not always be able to ping a device. Also, routers can be configured not to forward pings destined for other devices.

Establishing a network performance baseline requires collecting key performance data from the ports and devices that are essential to network operation.1 Gather symptoms - Troubleshooting begins with the process of gathering and documenting symptoms from the network, end systems, and users. Stage 2 Isolate the problem - The problem is not truly isolated until a single problem, or a set of related problems, is identified.

Users and Security Security domain The database administrator defines the names of the users who are allowed to access a database. A security domain defines the settings that apply to the user. Authentication mechanism A user who requires access to the database can be authenticated by one of the following: Data dictionary Operating system Network The means of authentication is specified at the time the user is defined in the database and can be altered later. This lesson covers authentication by database and by operating system only.

We now begin our look at building protocols using the basic tools that we have discussed. The discussion in this lecture will focus on issues of key establishment and the associated notion of authentication These protocols are not real, but instead are meant to serve just as a high-level survey Later lectures will go into specific protocols and will uncover practical challenges faced when implementing these protocols
