# Securitatea re\u021belelor WiFi domestice \u0219i de birou<\/p>\n
## De ce este important WiFi securizat?<\/p>\n
O re\u021bea WiFi nesecurizat\u0103 permite:
\n– Furtul datelor transmise
\n– Accesul la dispozitivele tale
\n– Folosirea internetului t\u0103u pentru activit\u0103\u021bi ilegale
\n– Atacuri Man-in-the-Middle
\n– Compromiterea \u00eentregii re\u021bele<\/p>\n
## Configurare router – Ghid complet<\/p>\n
### \ud83d\udd10 Primul pas: Accesarea router-ului<\/p>\n
1. **G\u0103se\u0219te IP-ul router-ului:**
\n– Windows: `ipconfig` \u2192 Default Gateway
\n– Mac\/Linux: `netstat -nr | grep default`
\n– Comun: 192.168.1.1 sau 192.168.0.1<\/p>\n
2. **Login \u00een interfa\u021ba admin:**
\n– Browser: http:\/\/[IP-router]
\n– User\/parol\u0103 pe eticheta router-ului
\n– SCHIMB\u0102 imediat creden\u021bialele default!<\/p>\n
### \ud83d\udee1\ufe0f Set\u0103ri esen\u021biale de securitate<\/p>\n
#### 1. Schimb\u0103 creden\u021bialele admin
\n– Username nou (nu ‘admin’)
\n– Parol\u0103 complex\u0103 (min. 15 caractere)
\n– Salveaz\u0103 \u00een manager de parole<\/p>\n
#### 2. Actualizeaz\u0103 firmware
\n– Verific\u0103 lunar pentru updates
\n– Activeaz\u0103 actualiz\u0103ri automate dac\u0103 disponibil
\n– Backup set\u0103ri \u00eenainte de update<\/p>\n
#### 3. Configurare WiFi securizat
\n– Protocol: WPA3 (sau WPA2 dac\u0103 WPA3 nu e disponibil)
\n– Criptare: AES
\n– Parol\u0103: Min. 15 caractere, complex
\n– SSID: Nu folosi informa\u021bii personale<\/p>\n
## Set\u0103ri avansate de securitate<\/p>\n
### \ud83d\udce1 SSID \u0219i Broadcasting<\/p>\n
#### Schimb\u0103 numele re\u021belei (SSID):
\n– \u274c NU folosi: nume personal, adres\u0103, model router
\n– \u2705 Folose\u0219te: nume neutru, creativ
\n– Exemplu: ‘PrettyFlyForAWiFi’, ‘TellMyWiFiLoveHer’<\/p>\n
#### SSID Broadcasting:
\n– **P\u0103streaz\u0103 activat** pentru utilizare normal\u0103
\n– Ascunderea SSID nu ofer\u0103 securitate real\u0103
\n– Poate cauza probleme de conectare<\/p>\n
### \ud83d\udd12 Tipuri de criptare<\/p>\n
#### WPA3 (Recomandat – 2018+)
\n– Cea mai nou\u0103 \u0219i sigur\u0103
\n– Protec\u021bie \u00eempotriva atacurilor offline
\n– Forward secrecy
\n– Necesit\u0103 dispozitive compatibile<\/p>\n
#### WPA2 (Minim acceptabil)
\n– Standard pentru dispozitive mai vechi
\n– Folose\u0219te doar cu AES
\n– Vulnerabil la KRACK (patchuit \u00een firmware nou)<\/p>\n
#### \u274c EVIT\u0102:
\n– WEP – Spart \u00een minute
\n– WPA cu TKIP – \u00cenvechit
\n– Re\u021bea deschis\u0103 – Zero securitate<\/p>\n
## Segregarea re\u021belei<\/p>\n
### \ud83c\udfe0 Re\u021bea principal\u0103
\nPentru dispozitive de \u00eencredere:
\n– Computere de lucru
\n– Telefoane personale
\n– Smart TV trusted<\/p>\n
### \ud83d\udc65 Re\u021bea Guest
\nPentru vizitatori \u0219i IoT:
\n– Izolat\u0103 de re\u021beaua principal\u0103
\n– Bandwidth limitat
\n– Acces temporar
\n– Parol\u0103 schimbat\u0103 regular<\/p>\n
### \ud83e\udd16 Re\u021bea IoT
\nPentru dispozitive smart:
\n– Izolat\u0103 complet
\n– F\u0103r\u0103 acces la re\u021beaua principal\u0103
\n– Monitorizare trafic
\n– Updates frecvente<\/p>\n
## Monitorizare \u0219i mentenan\u021b\u0103<\/p>\n
### \ud83d\udcca Ce s\u0103 monitorizezi:<\/p>\n
#### Dispozitive conectate:
\n– Verific\u0103 zilnic pentru intru\u0219i
\n– Noteaz\u0103 toate dispozitivele legitime
\n– Investigheaz\u0103 MAC-uri necunoscute<\/p>\n
#### Utilizare bandwidth:
\n– Identific\u0103 utilizare anormal\u0103
\n– Detecteaz\u0103 malware\/botnets
\n– Optimizeaz\u0103 QoS<\/p>\n
## WiFi public – Cum s\u0103 te protejezi<\/p>\n
### \u2615 La cafenea\/restaurant:<\/p>\n
#### \u26a0\ufe0f Pericole:
\n– Re\u021bele false (Evil Twin)
\n– Sniffing trafic
\n– Man-in-the-Middle
\n– Session hijacking<\/p>\n
#### \ud83d\udee1\ufe0f Protec\u021bie:
\n1. **Folose\u0219te VPN \u00ceNTOTDEAUNA**
\n2. **HTTPS only browsing**
\n3. **Nu online banking**
\n4. **Dezactiveaz\u0103 sharing**
\n5. **Forget network dup\u0103**<\/p>\n
