The Role of the Internet in the Propagation of Malware

Free registration required

Executive Summary

Computer threats have been a part of daily computing lives since 1986, when the boot sector virus Brain was discovered. Boot sector viruses propagated by writing themselves to floppy disks, then transferring to the user's PC when it booted up. This is due to the overwhelmingly efficient propagation capabilities it naturally offers, as well as the underground community it inadvertently supports. Between the vast number and array of threats available, coupled with the speed and efficiency with which the Internet has enabled them to travel, desktop security alone is unable to keep pace. This has resulted in the need for an additional layer of security at the network gateway to supplement the efforts at the client level.
