Wireless is typically less secure because it uses radio waves for transmission. In other words, you have your data "floating" in airspace which makes it more susceptible to being compromised (hacked). With a wired connection someone cannot "steal" your data frames (packets) unless they physically connect to the network cabling. Additionally, the level of security built into wireless technology is less advanced than that of wired networks. This is mainly due to the fact that 802.11 is a relatively newer protocol standard. Manufacturers (both hardware and software) are developing better security for wireless systems and it is possible to harden the security of a WLAN by using the current security protocols along with using some third-party software. For additional specific information read the RFC standards for 802.11.
