1. Nastavte si vlastn\u00ed heslo!<\/strong> Pokud jste si po\u0159\u00eddili WiFi router do sv\u00fdch domov\u016f nebo zam\u011bstn\u00e1n\u00ed, nenech\u00e1vejte jej v obecn\u00e9m nastaven\u00ed. Prvn\u00ed v\u011bc, kterou byste m\u011bli p\u0159i instalaci WiFi routeru ud\u011blat, je nastavit si vlastn\u00ed administr\u00e1torsk\u00e9 heslo pro p\u0159\u00edstup k administraci, a tak\u00e9 zvolit vlastn\u00ed heslo pro p\u0159ipojen\u00ed k va\u0161\u00ed WiFi s\u00edti. Hesla by nem\u011bla b\u00fdt trivi\u00e1ln\u00ed (obecn\u00e1 pojmenov\u00e1n\u00ed, jm\u00e9na osob), ide\u00e1ln\u00ed je kombinace mal\u00fdch\/velk\u00fdch p\u00edsmen, \u010d\u00edslic a speci\u00e1ln\u00edch znak\u016f.

Nastaven\u00ed filtrace najdete ve v\u011bt\u0161in\u011b WiFi router\u016f. Nejprve je pot\u0159eba aktivovat filtrov\u00e1n\u00ed MAC adres, a pot\u00e9 autorizovat v\u0161echna za\u0159\u00edzen\u00ed, kter\u00e1 jsou u\u017e k s\u00edti p\u0159ipojena.<\/p>\r\n

3. Vytvo\u0159te si samostatnou s\u00ed\u0165 pro hosty.<\/strong> Nastaven\u00ed WiFi router\u016f mysl\u00ed i na situace, kdy k v\u00e1m p\u0159ijde n\u00e1v\u0161t\u011bva, kter\u00e1 by se cht\u011bla p\u0159ipojit k va\u0161\u00ed WiFi.

4. Pozor p\u0159i p\u0159ipojen\u00ed k ve\u0159ejn\u00fdm WiFi s\u00edt\u00edm.<\/strong> Nikomu nev\u011b\u0159te. Doslova. P\u0159i p\u0159ipojov\u00e1n\u00ed k ve\u0159ejn\u00fdm WiFi s\u00edt\u00edm, nap\u0159. v kav\u00e1rn\u00e1ch, na \u010derpac\u00edch stanic\u00edch, v n\u00e1kupn\u00edch centrech, nezapom\u00ednejte na bezpe\u010dnost. Prov\u00e1d\u011bn\u00ed transakc\u00ed internetov\u00e9ho bankovnictv\u00ed nebo nakupov\u00e1n\u00ed s vyu\u017eit\u00edm platebn\u00ed karty bychom v\u00e1m v\u016fbec na ve\u0159ejn\u00fdch WiFi nedoporu\u010dovali. Obzvl\u00e1\u0161\u0165 byste se m\u011bli m\u00edt na pozoru u s\u00edt\u00ed, kter\u00e9 jsou zcela otev\u0159en\u00e9 (nemaj\u00ed v seznamu zobrazen\u00fdch dostupn\u00fdch WiFi u sv\u00e9ho n\u00e1zvu ikonu se z\u00e1mkem). Tyto zcela nezabezpe\u010den\u00e9 s\u00edt\u011b lze snadno napadnout a odposlouch\u00e1vat komunikaci p\u0159ipojen\u00fdch klient\u016f. Rad\u011bji volte zabezpe\u010denou s\u00ed\u0165, by\u0165 za cenu registrace s pou\u017eit\u00edm va\u0161\u00ed e-mailov\u00e9 adresy \u010di telefonu.<\/p>\r\n

5. P\u0159i surfov\u00e1n\u00ed na ve\u0159ejn\u00e9 WiFi pou\u017e\u00edvejte str\u00e1nky s \u0161ifrovan\u00fdm p\u0159enosem HTTPS.<\/strong> Pokud si na ve\u0159ejn\u00e9 WiFi nap\u0159. kontrolujete do\u0161l\u00e9 e-maily, m\u011bli byste k tomu \u00fa\u010delu pou\u017e\u00edvat pouze slu\u017eby HTTPS, kter\u00e9 vy\u017e\u00edvaj\u00ed \u0161ifrov\u00e1n\u00ed p\u0159en\u00e1\u0161en\u00fdch dat. Pro n\u00e1kupy, platby nebo pr\u00e1ci s internetov\u00fdm bankovnictv\u00edm vyu\u017e\u00edvejte rad\u011bji n\u011bkterou z b\u011b\u017en\u011b dostupn\u00fdch aplikac\u00ed VPN.<\/p>\r\n

6. Deaktivujte slu\u017eby p\u0159ipojen\u00ed na sv\u00fdch telefonech.<\/strong> Pokud se pohybujete s telefonem nebo tabletem mezi lidmi nap\u0159. ve ve\u0159ejn\u00fdch prost\u0159edc\u00edch dopravy, v kav\u00e1rn\u00e1ch, restaurac\u00edch, n\u00e1kupn\u00edch centrech, nezapom\u00ednejte v\u017edy deaktivovat WiFi a Bluetooth konektivity. Zamez\u00edte tak mo\u017enosti aktivn\u00edho p\u0159ipojen\u00ed nezvan\u00e9ho hosta, kter\u00fd by v\u00e1m mohl do za\u0159\u00edzen\u00ed implementovat \u0161kodliv\u00fd k\u00f3d. Nemluv\u011b o tom, \u017ee \u0161et\u0159\u00edte baterie sv\u00e9ho za\u0159\u00edzen\u00ed. Ani automatick\u00e9 p\u0159ipojov\u00e1n\u00ed ke zn\u00e1m\u00fdm ve\u0159ejn\u00fdm WiFi, kde u\u017e jste byli d\u0159\u00edve p\u0159ipojeni, nen\u00ed z hlediska bezpe\u010dnosti p\u0159\u00edli\u0161 vhodn\u00e9. Lep\u0161\u00ed je tedy konektivity vyp\u00ednat a aktivovat pouze v p\u0159\u00edpadech, kdy se skute\u010dn\u011b chcete p\u0159ipojit a m\u00e1te v\u0161e pod kontrolou.<\/p>\r\n
