“To protect Wi-Fi, you must use a strong password to connect to the network.
It is also worth including a restriction on connecting devices to hardware addresses,” said Permyakov.
To introduce this limitation, he clarified, you must first know the hardware address of the device.
“After that, you need to connect to the router’s configuration site, go through authorization, find the MAC filter and configure it,” the expert explained.
Permyakov also advises periodically changing the network access password, for example, every two months.
“You can understand that someone has connected to your network in two ways.
The router software can usually show who has connected to the system since the last start, indicating hardware addresses and (if possible) device type, operating system, network name.
If unfamiliar devices appear on this list, this is definitely an illegal connection, ”he explained.
Permyakov added that to detect such connections, there are special programs that periodically scan the network and collect information about connected devices.
Earlier, NTI analyst Denis Kuvikov said that the use of weak passwords is one of the main reasons for cyber attacks and fraud against Russians.
