Security Issues of WiFi – How it works
The rise in mobile internet triggered the need for wireless internet connectivity. Thus, the telcos started working on different ways to provide better, faster, and secure internet connections wirelessly. Almost every other person on Earth knows the word WiFi and is eager to connect to any free WiFi services on the go. Nonetheless, little do the people know about how WiFi works and what security issues threaten this technology. So, here we quickly review these important details for you.
About WiFi And Its Working
Wireless Fidelity or Wi-Fi refers to the provision of connectivity without wires. It works on Fibre Optics (FO) or Radio Frequency (RF). The international organization IEEE has set up a standard 802.11 protocol that has numerous variations offering different frequency and speed.
With WiFi, the data is processed in Gigahertz (GHz), usually 2.4 or 5GHz ranges, over radio frequency, and is handled (coded/decoded) using the 802.11 standards compliant routers and antennae.
Security Issues With WiFi
Unlike wired internet, a common problem with wireless connectivity or WiFi is its vulnerability to hacks. Anyone can ‘touch’ the data being passed over the RF, and thus, your activities are usually not private. Some of the common security issues with customer networks, public WiFi, and open connections are listed below.
- While connecting to WiFi, you cannot ascertain the security of the network.
- You cannot distinguish between a genuine open WiFi connection and an evil copy of it.
- You cannot ensure that your data being transmitted remains untouchable by any bad actors.
Public or Open WiFis are likely to become a hub of cybercriminals. Once they find your device connected to such a network, they can easily execute any malicious activity of their choice. Some of these include,
- Denial of service (dos) attacks
- Malware or spyware attacks
- Data breach and subsequent impersonation
- Rendering your device nonfunctional
- Ransomware attacks
Quick Tips For Using WiFi Securely
- Avoid connecting to public, open, and third-party WiFi networks.
- Make sure to have a VPN installed on your device. This will keep your online presence masked from the hackers. If connecting to VPN disconnects internet connectivity, you can simply reconnect it later after turning on the VPN.
- Make sure to visit only HTTPS secured websites. This will ensure that the data transmitted between your device and the website remains encrypted.
- Make sure to turn off any sharing options on your device before connecting to a public WiFi.
- Turn off WiFi when not needed
- Install a robust antimalware to proactively remove any possible malware reaching your device.
Because of the excessive dependence on the internet, one cannot simply avoid staying online on the go. Thus, using public and open WiFis is now becoming a necessity. Nonetheless, make sure you do not compromise your security.
