We are increasingly aware, and every year there are hundreds of attacks that remind us that connecting to a public WiFi network can be dangerous, and we must take a number of precautions, but do we know the dangers behind a Wi- Domestic fi? The answer is usually no. Although many users do not see it as a threat, Kaspersky Lab experts warn that, despite being among the four walls of our home, a domestic wireless router can be attacked and give us unpleasant surprises.
To prevent our home network from being hacked and all our devices are put in danger, you can follow a series of tips that increase your level of security.
Change the administrator password. A serious mistake that is made many times is to use the passwords that are defined by default, sometimes very simple. If this binds to any non-critical vulnerability or an open wireless connection, cybercriminals could take over the router. To avoid this, it is advisable to change the default password for a more complex one.
If not necessary, disable it. This is a universal rule. Today, routers, in addition to allowing you to access the Internet, also have different protocols for interconnecting and aligning connected devices such as Plug and Play (UPnP) or DLNA. Thus, the risk that the software suffers attacks by possible vulnerabilities by any of them will decrease. And if one is needed afterward, just activate it again.
Update the software. One of the most common mistakes is not to keep track of firmware updates, which means not having the latest versions of it, which usually include security patches against vulnerabilities, which are usually the gateway to cybercriminals. To keep it updated, you have to download the firmware image, make a backup of the router configuration, run the update and restore the configuration. As always, downloads must be made from official websites and not rely on suspicious resources. The latest versions available along with manuals that indicate how to update are usually found on each vendor’s website.
Disable remote administration. Open access to the router interface can become a problem. Although manufacturers usually only allow LAN control of the device by default, it is not always the case. Check if that interface is available on the Internet. To disable remote administration, normally, you must deactivate a box or enter the address 0.0.0.0 in the appropriate field. Kaspersky Lab experts also recommend blocking access to the router, whenever your connection allows, through Telnet or SSH protocols.
Make it not visible. The WiFi network ID (SSID) is transmitted worldwide, as usual. To prevent anyone from knowing the ID, this option must be unchecked, disabling the issuance of identity. The network will not be hacked so easily, but you must enter the SSID every time you want a device to connect.
Use trusted encryption. Leaving the network open to neighbors to connect can be an act of generosity, but it can also lead to serious problems since one of them can use your connection to steal your personal data or to commit a cybercrime against others, and the police will look for the owner Of the same. Therefore, Kaspersky Lab experts recommend enabling WPA2 encryption and setting a strong password.
Use common sense. Being sensible when updating and using the home WiFi network decreases the chances of it being hacked. Using a good security solution that allows you to check the security level of the wireless network and advise on how to configure the correct settings can be of great help.…Read More
