Firewall technology is a young but quickly maturing industry. The first generation of firewall architectures has been around almost as long as routers, first appearing around 1985 and coming out of Cisco's IOS software division. These firewalls are called packet filter firewalls. However, the first paper describing the screening process used by packet filter firewalls did not appear until 1988, when Jeff
Mogul from Digital Equipment Corporation published his studies. At this time we are in the Fourth generation of firewall devices and software.

Explanation:
All data should be archived. A full backup copies all the data from the system to the backup medium. After the full backup has finished, the backup media is physically transported to another off-site location.
Incorrect Answers:
A: Archiving should copy all the data, but an incremental backup copies only the files that have been modified since the previous backup.
B: There is no special off-site backup method. Instead use a standard full backup and transport the backup media to the other site.
D: Archiving should copy all the data, but a differential backup copies only the difference in the data since the last full backup.

The Biba security model addresses the integrity of data being threatened when subjects at lower security levels are able to write to objects at higher security levels and when subjects can read data at lower levels.
