By | May 7, 2017

Wi-Fi is the incredible concept that has made life so much easier in contemporary times. However, it’s a fact at the same time that many myths have started being associated with the technology, especially with its security. It is essential to stay away of such myths and stay assured about the usage. Given below are some of such Wi-Fi security myths those need to be addressed immediately.

Myth No. 1: The SSID should not be showcased

It is here to note that every wireless router or wireless access point is given a network name. The name is technically called as SSID or Service Set Identifier. The basic purpose of showing this SSID is to make the user find its entire network over its PC or any other device. Some make it invisible keeping the group of people who they don’t want over their network.

This is a misconception as some devices, especially those running on Windows 7 or later editions can still find every network. In addition, hiding the SSID sometimes drag the attention of the Wi-Fi hackers giving them the hint that your network has something interesting or sensational. In fact, there are the network analyzers like Kismet available these days with ability to fetch a SSID from the airwaves in an effortless fashion.

Myth No. 2: Using MAC address screening for better protection

MAC or the Media Access Control addresses are meant to recognize each of the devices over the network. This address is considered as a recognition while sending or capturing data over the network. It’s certainly a myth that one can protect the network and restrict the anonymous devices to join it by configuring the router to allow only the devices having certain MAC addresses.

It is here to note that a hacker through network analyzer can also see MAC addresses.

Myth No. 3: Number of devices can be controlled through IP address pool

Each device over a network is distinguished by a specific IP address. This is not certainly true that the router is going to take the Dynamic Host Control Protocol of DHCP server to provide a special IP address to every device that joins the network, through the usual MAC address that the device delivers to the router. It’s a complete myth that one can control the number of devices that can be the part of his network by controlling the pool of IP addresses his router can draw.  

Myth No. 4: Disabling DHCP server for better protection

This is a complete myth. A device not having any IP address can never be able in joining the network. Here the person has list the whole IP addresses and the concerned devices for those. In addition, each device has to be configured as well manually to use its particular IP.

Problem associated with this is that if a hacker has already entered the network, a simple IP scan can identify the IPs your network is using. A hacker can simply assign a similar address to a device for having full access of the network. Limiting the IP address or assigning those manually is nothing but complicating the process of new connection to a network.   

Myth No. 5: Small networks are tough to be misused

This is a common myth that says that minimizing the wireless router’s transmission power makes it difficult for the outsiders to get in to the network, as they are not going to be able in detecting it. This is something the silliest security idea that one can have for protecting the network. The strategy is quite simple actually; someone willing to crack the wireless network can make it happen simply by using a large antenna and pick the router’s signal. Minimizing the router’s transmission power can simply lower its range and efficacy for authentic users.
