What is the importance of securing my wireless network?
Securing your wireless network is crucial in today’s digital age. With the rise of online threats and cyberattacks, an unsecured network can leave your personal data and devices vulnerable to hackers. Moreover, an open network can also allow unauthorized users to access your internet connection, slowing down your speeds and consuming your bandwidth.
By securing your wireless network, you can protect your sensitive information, prevent identity theft, and ensure that your devices and data are safe from prying eyes. A secure network also means that you can have peace of mind when browsing the internet, making online transactions, or streaming content.
What are the common types of wireless network attacks?
There are several types of wireless network attacks that you should be aware of. One of the most common types is the Man-in-the-Middle (MITM) attack, where hackers intercept your internet traffic to steal sensitive information. Another type is the Denial of Service (DoS) attack, which involves flooding your network with traffic to overwhelm it and make it unavailable.
Other types of attacks include Rogue Access Point (AP) attacks, where hackers create a fake Wi-Fi hotspot to lure victims, and Evil Twin attacks, where hackers create a fake AP with a similar name to yours to steal login credentials. There are alsoDrive-by attacks, where hackers exploit vulnerabilities in your network to gain access to your devices and data.
How do I change my router’s admin password?
Changing your router’s admin password is a crucial step in securing your wireless network. To do this, you’ll need to access your router’s web-based interface.
