From my reference materials from Cisco and previous work history, I firmly believe that the #1 issue surrounding the deployment of a wireless network is wireless security. Specifically, passive monitoring, unauthorized access, and DoS attacks.
Passive Monitoring – wireless networks are intentionally designed to propagate data throughout buildings and areas, almost always resulting in the radio signals traveling beyond the limits of the area. By default, wireless devices are configured for maximum transmit (Tx) power on the wireless radio configuration. This will allow an eavesdropper, hacker, or intruder an opportunity to passively retrieve data without being noticed by network management personnel.
Unauthorized Access – If a person can connect …show more content…
A simple TCP port scanner will tell an intruder many things about vulnerabilities within the network. A hacker can take advantage of an open port’s utilities to directly access sensitive information or even reconfigure the network in a nefarious manner to allow easier access. One common way of accessing a wireless LAN unauthorized is to stage a Man-in-the-middle attack. One way to do this is to exploit the TCP/IP Address Resolution Protocol (ARP) functions. ARP is what a wireless station (access point, laptop, etc) uses to discover the physical address (MAC) of a destination wireless station. The MAC is embedded in networking devices from the manufacturer and is the de facto physical address or identifier of networking devices, same as the mailing address of a person’s home. The software sending data to a destination will have the destination IP address, but the sending station’s wireless radio must use ARP to discover the physical address (MAC) tied to the virtual address (IP address.) An ARP request packet is broadcast to all network devices announcing the destination’s IP address that is being sought. All stations within “hearing” range

ManageEngine Desktop Central is prone to a security-bypass vulnerability related to the password-reset feature. An attacker can exploit this to reset the application’s administrator password and gain administrative privileges. On 27 March 2015, a proof of concept (PoC) exploit code was released on multiple websites such as Seclist.org and PacketStormSecurity.com. Open source research did not reveal any instances of this vulnerability in the wild. However, this does not mean that malicious actors…
