If your company's wireless systems are breached and a hacker is able to obtain access to your internal computers, several bad things can happen. First off, the attacker can gather information about your systems and their configuration, which can lead to further attacks. The exposure of this information can lead to big problems, such as:

• Leakage of confidential information, including files being copied and private information such as social security numbers and credit-card numbers being stolen
• Passwords being cracked and used to carry out other attacks
• Servers being shut down, rebooted, or taken completely offline
• Entire databases being copied, corrupted, or deleted

Although wireless networks are used as a niche solution for many organizations, others are completely dependent on them for all their network connectivity. Either way, wireless networks can serve as an entry point to your workstations, servers, and other wired systems. Therefore, if your wireless client security vulnerabilities aren't addressed and managed properly, they can pose unnecessary risks to the entire network and organization.
