Le password sono la prima barriera di accesso a dati che vogliamo
tenere per noi.
Le usiamo leggere la posta, per ritirare al bancomat (pin), per entrare
nel computer e nei mille servizi digitali a cui accediamo.
--
### Ma...
Non siamo bravi a scegliere delle buone password
- E' la password di gmail?
➜ ci mettiamo `gmail` in mezzo
- Usiamo concetti ricordabili
➜ date di nascita, nomi di amic\*/compagn\*
- Riusiamo la stessa password in molti posti.
In pratica scegliamo password facilmente indovinabili.
--
Spinti a migliorare le nostre password

--
scegliamo le soluzioni piu' semplici e prevedibili
- e' la password di facebook ➜ **facebookpassword**
- inserisci almeno una maiuscola ➜ **Facebookpassword**
- inserisci almeno un numero ➜ **Facebookpassword1**
- inserisci almeno un simbolo ➜ **Facebookpassword1!**
notes:
Sono tutti schemi facilmente immaginabili.

### Ma soprattutto..
Usiamo la stessa password per più siti/servizi

notes:
chiedere perche' e' un problema....
--
### Orrore!
i dipendenti di alcuni servizi hanno accesso ad ogni altro servizio!
quando (non se) uno dei servizi viene bucato, gente a caso ha accesso ad ogni vostro servizio (se leggete i giornali, succede un giorno si e l'altro pure).
E' talmente diffusa la cosa che mozilla ha un servizio per fare
un check ➜ [monitor.firefox.com](https://monitor.firefox.com)
--
### Leak
Negli ultimi anni sono stati bucati tanti servizi e milioni di password sono diventate pubbliche (leak)
permettendo di farci ricerca sopra e si, le password piu' usate sono `123456` e `password`,
gli schemi usati sono drammaticamente ricorrenti e la maggior parte delle persone riusa
le password in piu' servizi.
Una lista di servizi la cui compromissione è pubblica è [qui](https://haveibeenpwned.com/PwnedWebsites)
--
### Password Cracking
Esistono programmi e servizi che tentano ripetutamente password basandosi sulla nostra prevedibilità
e si basano comunemente su dizionari a cui vengono applicate delle regole (permutazioni, aggiunte di prefissi/suffissi,
cambio di caratteri comuni, maiuscole/minuscole).
Considerate che i file dizionario in attacchi mirati vengono creati ad-hoc prendendo tutto il material digitale del target.
notes:
Mostrare un piccolo esempio di `hashcat` (da preparare)
--
### E quindi?
Se non siamo capaci a fare qualcosa, cerchiamo qualcuno in grado di farlo.
--
### Password manager
Usiamo i password manager.
Sono dei programmi che generano e si ricordano delle password sicure,
in cambio di una sola master password (passphrase).
notes:
spiegare master password, che e' possibile fare piu' liste di password, suggerire buone pratiche.
--
### E la master password?
Per le poche passphrase che non possiamo salvare usiamo i seguenti accorgimenti:
- mai riusare una passphrase (dai te ne devi ricordare massimo 4, stacce)
- mai condividere una passphrase (no no no e no)
- mai scrivere una passphrase (a parte se sai quello che stai facendo)
- usa 4 parole a caso (veramente a caso) e costruiscici una storia sopra per ricordarle.
notes:
il `4` del primo punto e' un numero a caso.
esempio live di scelta passphrase.
