Why is it important to protect a Wi Fi nand what should you do to protect your Wi Fi network?
One must keep the Wi-Fi network as safe as possible to protect the data from being accessed by anyone & avoid any unwanted connections.
To secure oneself from any snooping as hackers once joined to the Wi-Fi Network may access what one is doing on the Internet. Hence, it is nice to note that one keeps the Wi-Fi network safe, protected & secure.
One should know the following points to secure the wireless Network.
1. Set a Secure Pass Key
The first and foremost point to be noted is to protect the Wi-Fi network by keeping a secure passkey. It is necessary that one set up a strong password that is quite difficult to learn. We should say that one must use a combination of numbers, letters, & special characters in the passkey.
Additionally, alter the default, old passkey. This shall save any unwanted person from joining the network & lessen the data easily & one shall have all of the bandwidth to oneself.
2. MAC Addresses’ Filtering
By keeping and MAC Address may too aid in preventing any unwanted access to the network. Many of the gadgets joined to the network have a rare MAC address, which is similar to the IP address case.
One may keep the MAC addresses of all the gadgets to the Wireless Router settings & later, only the particular gadgets shall join the Wi-Fi network.
3. Change the Wi-Fi Network’s name (SSID)
Altering the Wi-Fi Network’s name (SSID) is a crucial point to be taken care of. When one gets a new router, the SSID usually is set as default by the company.
One must alter the SSID & this shall disconnect any gadget that was earlier joined to the Wi-Fi network & only by using the new password, they shall have to re-connect to the network.
4. Keep Router Firmware Updated
One must always keep the router up to date with the latest firmware version. The old versions of firmware can have bugs & few issues related to security.
The router must be kept secure from most of the bugs, which is possible only when the router is on the firmware’s latest version. The updates may patch the bugs instantly.
5. Limit the Wi-Fi Signals’ range
If one resides in a congested area or small apartment & the Wi-Fi router has a long-range, one must reduce the wireless router’s range by altering the router’s mode 802.11g instead of 802.11b or 802.11n. One must try using another wireless channel too.
By placing a metal item nearby, one may limit the signals that shall fluctuate the router’s signals. After this, it will be followed by lessening the signals or placing metal foil around the router’s antenna.
6. Use a firewall
The hardware firewalls give the best defense against attacks coming from outside of the network, & as many routers have firewalls built into them, they check data going out & coming in & block any dubious activity. The gadgets are customarily set with reasonable defaults that make sure that they do good work.
Many firewalls use packet filtering, which seems to get its destination & source addresses at the header of a packet. These details are compared to a set of user-created and predefined rules that check if the packet is original or not & if it’s to be allowed, removed, or quarantined.
The firewalls (Software) typically work on the endpoint laptop or desktop, with the merit of giving a good point on what network traffic is going via the gadget.
More than just where data is going & which ports are being utilized, it shall let you know which apps. are usually utilized & may block or allow that is the program’s ability to receive and send data.
It may ask the user what it must do before it allows or blocks traffic when the software firewall isn’t sure about a specific program.
7. Hide the name of the network
Access points of Wi-Fi are generally maintained by default to broadcast the wireless network name – called the SSID or service set identifier, to make it easy to locate & join.
One may have to know the name of the network before one may join the router. This shows that the SSID has to be set to “hidden.”
As it provided that employees should know the company’s name of the Wi-Fi network, & in a household for friends & family members, it is terrible to broadcast it so that anyone may locate it, & try to even sneak into the privacy.
It’s necessary to note that hiding the SSID must never be the mere measure one may take to secure the Wi-Fi network, as hackers using Wi-Fi scanning tools. A tool such as airodump-ng may still detect the network & its SSID even when it is kept “hidden.”
But multiple layers of protection are assured by security, & one may avoid getting the unnecessary attention of hackers by hiding the SSID. Hence, it is a suitable method that must be used by everyone.
8. Give a separate network for guests
It is good to provide a guest network if one requires to have visitors to utilize the Wi-Fi. This means that they may join the net without getting access to the company or family’s internal network. This is necessary both, i.e., to prevent them from infecting the network with viruses or other malware & for security reasons.
One technique is by utilizing a specific net connection with its wireless access point. This is rarely necessary as many old & many new user wireless routers have the strength of having two Wi-Fi networks at once – the leading network & another for guests (which is called SSID “Guest.”
