There are few if any legitimate reasons to allow port scanning. In some cases sites may protect themselves from port scanning by blocking the site they are being scanned from resulting in other users of that scanner's ISP being blocked from that website. Also since recent worms have used port scanning to look for systems to infect, blocking port scanninghelps to reduce the rate at which these worms spread.If there is a legitimate reason for finding out what ports are open on a server there are more appropriate ways of finding this out.
Vertical scanning = Scanning all ports on one or more host ..and Horizontal scannig =scanning one port on many host. When someone is performing vertical scanning, he/she is interested in any open ports and launching an attack on it from a Database of vulnerabilities. The objective is to attack , no matter what kind of attack it is. On the other hand - horizontal scanning attempts to launch a particular type of attack , so it is interested in only a particular open port in different host. Vertical scanning has more number of ports to scan than horizontal scanning. Hence it takes more time - making it slower than horizontal scanning.
Captain of the port.

P2P is both a security issue (personal and computer security) and because so much intellectual property is uploaded illegally on p2p networks it is also a copyright issue.
Security is both a technology and a business issue. Without security, the business would be able to operate effectively and customers wouldn't trust the company with their information.
