Basic tips so that they do not attack your router

What to do so that the router is always protected

These must be taken into account advice both for the main device that we have, as well as if we are using an old router to use it as a repeater or any other function. In all cases it must be protected and thus reduce the possibility of a hacker to gain access and put privacy at risk.

Do not leave the router as it comes from the factory

Something very important is change factory settings with the router. If we keep them, it can facilitate the entry of any intruder. For example we talk about changing the name of the network, security settings, passwords …

Normally the name of the router will reflect the model and even the telephone operator that we are using. This could help attackers search for potential vulnerabilities or carry out a strategy to break into the device and compromise security.

Prevent vulnerabilities

Of course another essential point is avoid security breaches. The vulnerabilities are present in all types of devices, but they are especially sensitive if we talk about a router, since it is permanently connected to the network and also serves to establish connection with many other devices.

Our advice is to always update the firmware of the device. We must never leave an outdated version, which may have vulnerabilities. This must also be applied to any other device that we have connected to the device.

Always use strong passwords

Another very important question is to use keys that are really safe. Here we must mention both the Wi-Fi network and the password to access the router and its configuration. We must never leave the one that comes from the factory, but we must also generate a really strong one.

There are many methods of stealing passwords on the Internet. A safe one is one that is totally random, that has different symbols, numbers and letters (both uppercase and lowercase). Also, that key should not be used anywhere.

It will also be imperative that the encryption that we use is appropriate. Sometimes the security problem that attackers take advantage of is that we are using outdated encryption, such as WEP. We must always use a safe, current one, such as WPA-3 or, failing that, WPA-2.

Also protect connected devices

But it is not only necessary to protect the router itself, but also any device that we have connected. If there are vulnerabilities on other machines, they could use them as a bridge to reach others. We are talking about computers, mobile phones, tablets … But also what is known as the Internet of Things.

We must apply the tips that we have mentioned above. We must always have good passwords, updated equipment and minimize the possible vulnerabilities that may appear.

Constant review

But something that we should not ignore is the fact of maintaining a Periodic revision. If we want to avoid intruders in the router, something fundamental is to check that there are precisely no unknown computers connected to the device.

For this we can enter the router, in its configuration, and see which devices are connected at that moment or which have been connected recently. Also check that the encryption is adequate, that it is up to date and, in addition, change the password from time to time.
