Kala shaandheynta cinwaanka MAC^(MAC) waa mid ka mid ah astaamaha muranka dhaliyay ee dadka qaar ay ku dhaartaan, halka qaar kalena ay yiraahdaan waa waqti lumis iyo kheyraad dhammaystiran. Haddaba waa kee? Fikradayda, waa labadaba, iyada oo ku xidhan waxa aad isku dayayso inaad ku guulaysato adigoo isticmaalaya.

Nasiib darrose, sifadan waxa loo suuqgeyn karaa sidii kor loogu qaadi lahaa amniga oo aad isticmaali karto haddii aad farsamo ahaan aqoon u leedahay oo aad diyaar u tahay inaad dadaalka geliso. Xaqiiqda dhabta ah ee arrintu waa in aysan runtii bixinaynin ammaan dheeri ah waxayna dhab ahaantii ka dhigi kartaa shabakadaada WiFi mid aan ammaan ahayn! ^(WiFi)Ha werwerin, wax badan oo arrintan ku saabsan ayaan hoos ku sharixi doonaa.

Si kastaba ha ahaatee, gabi ahaanba ma aha wax faa'iido leh. Waxaa jira kiisas sharci ah oo aad ku isticmaali karto shaandhaynta cinwaanka MAC ee shabakadaada, laakiin kuma dari doonto ammaan dheeraad ah. Taa baddalkeeda, waa wax badan oo ka mid ah qalabka maamulka oo aad isticmaali karto si aad u xakameyso in carruurtaada ay geli karaan internetka^(Internet) waqtiyo gaar ah inta lagu jiro maalinta ama haddii aad rabto inaad gacanta ku darto qalabka shabakadaada, taas oo aad la socon karto.

Waa maxay sababta aysan shabakadaada uga ^(Network)dhigin^(Make) mid amaan ah

Sababta ugu weyn ee aysan uga dhigin shabakadaada mid amaan ah waa sababta oo ah runtii way fududahay in la xoqo cinwaanka MAC^{(spoof a MAC address)} . Hacker-ka shabakada, oo runtii noqon kara qof kasta maadaama qalabyadu aad u fududahay in la isticmaalo, ayaa si fudud u ogaan kara ciwaannada MAC ee shabakadaada ka dibna ciwaankaas ku dheji kombuyutarkooda.

Marka, waxaa laga yaabaa inaad weydiiso, sidee ku heli karaan cinwaankaaga MAC haddii aysan ku xirmi karin shabakadaada? Hagaag, taasi waa daciifnimo ku jirta WiFi . Xitaa iyada oo leh shabakad sir ah oo WPA2 ah, cinwaannada ^(WPA2)MAC ee xirmooyinkaas lama sir ah. Tani waxay ka dhigan tahay in qof kasta oo haysta software urinaya shabakad iyo kaarka wireless ee kala duwan ee shabakadaada, uu si fudud u qabsan karo dhammaan ciwaannada MAC ee kula hadlaya routerkaaga.

Ma arki karaan xogta ama wax la mid ah, laakiin dhab ahaantii maaha inay jebiyaan sirta si ay u galaan shabakadaada. Waa maxay sababtu? Sababtoo ah hadda oo ay haystaan ​​cinwaankaaga MAC , way ku dhejin karaan ka dibna waxay u diri karaan baakidhyo gaar ah router kaaga oo loo yaqaan 'disassociation packets', kaas oo ka saari doona qalabkaaga shabakada wireless.

Kadib, aaladda jabsadayaashu waxay isku dayi doonaan inay ku xidhmaan router-ka waana la aqbali doonaa sababtoo ah hadda waxay isticmaalayaan cinwaankaaga MAC oo sax ah. Tani waa sababta aan mar hore u sheegay in habkani uu ka dhigi karo mid aan ammaan ahayn shabakadaada sababtoo ah hadda hackers ma aha inuu isku dayo inuu isku dayo inuu jebiyo eraygaaga sirta ah ee WPA2 gabi ahaanba! ^(WPA2)Waa inay iska dhigaan kombuyuutar la aamini karo.

Mar labaad, tan waxaa samayn kara qof aan aqoon u lahayn kombuyuutarrada. Haddii aad kaliya Google dildilaacdo WiFi adoo isticmaalaya Kali Linux , waxaad heli doontaa casharro badan oo ku saabsan sida loo ^{(Kali Linux)}jabsado WiFi^(WiFi) deriskaaga dhowr daqiiqo gudahood. Haddaba qalabkaas had iyo jeer ma shaqeeyaan?

Habka ugu Wanaagsan ee Lagugu Sugo Amaanka

Aaladahaasi way shaqayn doonaan, laakiin maaha haddii aad isticmaalayso sirta WPA2 oo ay la socoto furaha sirta ah ee ^(WPA2)WiFi dheer . Runtii waa muhiim inaadan isticmaalin furaha WiFi fudud oo gaaban sababtoo ah dhammaan hackers-ku sameeyo marka la isticmaalayo qalabkan waa weerar xoog leh.

Weerar xoog leh, waxay qabsan doonaan erayga sirta ah ee qarsoon waxayna isku dayi doonaan inay jebiyaan iyaga oo isticmaalaya mishiinka ugu dhakhsaha badan iyo qaamuuska ugu weyn ee ereyada sirta ah ee ay heli karaan. Haddii eraygaaga sirta ah uu sugan yahay, waxay qaadan kartaa sanado in erayga sirta ah la dilaaco. Had iyo jeer isku day inaad ku isticmaasho WPA2 AES oo keliya. Waa inaad ka fogaataa WPA [TKIP] + WPA2 [ AES ] doorashada maadaama ay aad uga yar tahay ammaanka.

Si kastaba ha noqotee, haddii aad leedahay shaandhaynta cinwaanka MAC , hackers-ku wuxuu dhaafi karaa dhammaan dhibaatooyinkaas oo si fudud u qabsan karaa cinwaankaaga MAC , ka gooyay adiga ama aalad kale oo ku taal shabakaddaada router oo si xor ah ugu xidh. Marka ay gudaha galaan, waxay samayn karaan dhammaan noocyada waxyeellada waxayna geli karaan wax kasta oo shabakadaada ah.

Xalka kale ee Dhibaatada

Laakiin dadka qaar ayaa wali odhan doona waa faa'iido badan si loo xakameeyo cidda ka heli karta shabakadayda, gaar ahaan maadaama qof kastaa aanu garanayn sida loo isticmaalo qalabka aan kor ku soo sheegay. OK, taasi waa dhibic, laakiin xalka ugu fiican ee lagu xakameynayo dadka ka baxsan ee raba inay ku xidhmaan shabakadaada waa inaad isticmaasho shabakad WiFi martida ah.

Ku dhawaad ​​​​dhammaan jiheeyayaasha casriga ah waxay leeyihiin muuqaal WiFi marti ah kaasoo kuu oggolaanaya inaad u oggolaato dadka kale inay ku xidhmaan shabakadaada, laakiin ha u oggolaan inay wax ku arkaan shabakadda gurigaaga. Haddii router-kaagu aanu taageerin, waxa kaliya oo aad iibsan kartaa router raqiis ah oo aad ku xidhi kartaa shabakadaada furaha sirta ah iyo kala duwanaanshaha ciwaanka IP-ga ee goonida ah.

Waxa kale oo xusid mudan in ammaanka WiFi ee kale ee “kor u qaadis” sida curyaaminta baahinta SSID ay sidoo kale ka dhigi doonto shabakaddaada mid^(LESS) ammaan ah, oo aan ammaan ahayn. Mid kale oo ay dadku ii sheegeen inay isku dayaan waa inay adeegsadaan ciwaanka IP-ga ee taagan. Mar labaad^(Again) , ilaa inta uu jabsadayhu ogaan karo kala duwanaanshahaaga shabakadda IP-ga, waxay isticmaali karaan ciwaan kasta oo xadkaas ku jira mishiinkooda, iyada oo aan loo eegin haddii aad u qoondaysay IP-gaas iyo haddii kale.

Waxaan rajeyneynaa, tani waxay ku siineysaa fikrad cad oo ku saabsan waxa aad u isticmaali karto shaandhaynta cinwaanka MAC iyo waxa laga filayo. ^(MAC)Haddii aad dareento si ka duwan, xor ayaad u tahay inaad nagu ogeysiiso faallooyinka. Ku raaxayso!

Does MAC Address Filtering Really Protect Your WiFi?

MAC addresѕ filterіng is one of those controverѕial features that some people swear by, whereas otherѕ say it’s a complete waste of time and resources. So which is it? In my opinion, it’s both, depending on what you are tryіng to аcсomplish by usіng it.

Unfortunately, this feature is marketed as a security enhancement that you can use if you are technically-savvy and willing to put in the effort. The real fact of the matter is that it really provides no extra security and can actually make your WiFi network less secure! Don’t worry, I’ll explain more about that below.

However, it’s not completely useless. There are some legitimate cases where you can use MAC address filtering on your network, but it won’t add additional security. Instead, it’s more of an administration tool that you can use to control whether or not your kids can access the Internet at certain times during the day or if you want to manually add devices to your network, which you can monitor.

Why It Doesn’t Make Your Network More Secure

The main reason why it doesn’t make your network more secure is because it’s really easy to spoof a MAC address. A network hacker, which can literally be anyone since the tools are so easy to use, can easily figure out the MAC addresses on your network and then spoof that address onto their computer.

So, you may ask, how can they get your MAC address if they can’t connect to your network? Well, that’s an inherent weakness with WiFi. Even with a WPA2 encrypted network, the MAC addresses on those packets are not encrypted. This means that anyone with network sniffing software installed and a wireless card in range of your network, can easily grab all the MAC addresses that are communicating with your router.

They can’t see the data or anything like that, but they don’t really have to break the encryption to access your network. Why? Because now that they have your MAC address, they can spoof it and then send out special packets to your router called disassociation packets, which will disconnect your device from the wireless network.

Then, the hackers’ device will try to connect to the router and will be accepted because it is now using your valid MAC address. This is why I said earlier that this feature can make your network less secure because now the hacker doesn’t have to bother trying to crack your WPA2 encrypted password at all! They simply have to pretend to be a trusted computer.

Again, this can be done by someone who little to no knowledge of computers. If you just Google crack WiFi using Kali Linux, you’ll get tons of tutorials on how to hack into your neighbor’s WiFi within a few minutes. So do those tools always work?

The Best Way to Stay Secure

Those tools will work, but not if you are using WPA2 encryption along with a fairly long WiFi password. It’s really important that you don’t use a simple and short WiFi password because all a hacker does when using these tools is a brute force attack.

With a brute force attack, they will capture the encrypted password and try to crack it using the fastest machine and the biggest dictionary of passwords they can find. If your password is secure, it can take years for the password to be cracked. Always try to use WPA2 with AES only. You should avoid the WPA [TKIP] + WPA2 [AES] option as it’s much less secure.

However, if you have MAC address filtering enabled, the hacker can bypass all that trouble and simply grab your MAC address, spoof it, disconnect you or another device on your network from the router and connect freely. Once they are in, they can do all kinds of damage and access everything on your network.

Other Solutions to the Problem

But some people will still say it’s so useful to control who can get on my network, especially since everyone doesn’t know how to use the tools I mentioned above. OK, that’s a point, but a better solution to control outsiders who want to connect to your network is to use a guest WiFi network.

Just about all modern routers have a guest WiFi feature that will allow you to let others connect to your network, but not let them see anything on your home network. If your router doesn’t support it, you can just purchase a cheap router and attach that to your network with a separate password and separate IP address range.

It’s also worth noting that other WiFi security “enhancements” like disabling SSID broadcasting will also make your network LESS secure, not more secure. Another one people have told me they try is to use static IP addressing. Again, as long as a hacker can figure out your network IP range, they can use any address in that range too on their machine, regardless of whether you have assigned that IP or not.

Hopefully, this gives you a clear idea of what you can use MAC addressing filtering for and what expectations to have. If you feel differently, feel free to let us know in the comments. Enjoy!
