However, there are many security risks associated with the current wireless protocols and encryption methods, and in the carelessness and ignorance that exists at the user and corporate IT level.Hacking methods have become much more sophisticated and innovative with wireless access.
If router security is not activated or if the owner deactivates it for convenience, it creates a free hotspot.
Hence, it is important to understand the characteristics of such applications and evaluate the vulnerabilities bearing the highest risk in this context.
Evaluation of these vulnerabilities and the resulting vulnerability catalogs in an industrial context when considering WLAN, NFC and Zig Bee are available.
Wireless security is the prevention of unauthorized access or damage to computers using wireless networks.
The most common types of wireless security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). The password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools.
There were relatively few dangers when wireless technology was first introduced, as the effort to maintain the communication was high and the effort to intrude is always higher.
The variety of risks to users of wireless technology have increased as the service has become more popular and the technology more commonly available.
The ability to enter a network while mobile has great benefits.
However, wireless networking is prone to some security issues.
However, there are effective countermeasures (like disabling open switchports during switch configuration and VLAN configuration to limit network access) that are available to protect both the network and the information it contains, but such countermeasures must be applied uniformly to all network devices.
Due to its availability and low cost, the use of wireless communication technologies increases in domains beyond the originally intended usage areas, e.g. Such industrial applications often have specific security requirements.
Enterprises often enforce security using a certificate-based system to authenticate the connecting device, following the standard 802.1X.
