+# Utilizzo avanzato del terminale
+
+In questa sezione verranno discussi gli utilizzi più avanzati del
+terminale. In particolare, ci si soffermerà sui cosidetti *terminal
+multiplexer*.
+
+## I *terminal multiplexer*
+
+I terminal multiplexer in Linux sono strumenti potenti che consentono
+agli utenti di creare più sessioni di terminale all'interno di una
+singola finestra del terminale. Questi strumenti sono particolarmente
+utili per gestire più processi contemporaneamente, mantenendo aperte
+le sessioni anche dopo la disconnessione, e per organizzare le
+finestre del terminale in modo efficiente.
+
+Uno dei terminal multiplexer più popolari e ampiamente utilizzati è
+`tmux`. `tmux` permette agli utenti di creare, gestire e navigare tra
+più sessioni di terminale, facilitando l'organizzazione dei processi e
+la gestione delle finestre. Con `tmux`, è possibile dividere la
+finestra del terminale in più riquadri, ciascuno dei quali può
+eseguire un processo separato, e passare facilmente da una sessione
+all'altra.
+
+Un altro esempio di terminal multiplexer è `screen`, che offre
+funzionalità simili a `tmux` ma con una sintassi leggermente
+diversa. Entrambi gli strumenti sono disponibili per la maggior parte
+delle distribuzioni Linux e possono essere installati tramite il
+gestore di pacchetti della distribuzione.
+
+Utilizzare un terminal multiplexer può migliorare notevolmente
+l'efficienza e la produttività degli sviluppatori e degli
+amministratori di sistema, consentendo di lavorare con più processi
+contemporaneamente senza dover aprire molteplici finestre del
+terminale.

+
+## Introduzione a `tmux`
+
+`tmux` è un potente strumento di gestione delle sessioni di terminale
+in Linux. Permette agli utenti di creare, gestire e navigare tra più
+sessioni di terminale all'interno di una singola finestra del
+terminale. Questa funzionalità è particolarmente utile per
+l'esecuzione di più programmi con una singola connessione, come quando
+si effettua una connessione remota a una macchina utilizzando Secure
+Shell (SSH) [1].
+
+Per iniziare ad utilizzare `tmux`, basta digitare `tmux` nel
+terminale. Questo comando avvia un server `tmux`, crea una sessione
+predefinita (numero 0) con una singola finestra e si collega ad
+essa. Una volta connessi a `tmux`, è possibile eseguire qualsiasi
+comando o programma come si farebbe normalmente.
+
+## Installazione di `tmux`
+
+`tmux` è un'applicazione disponibile nel repository di `Arch
+Linux`. Per installarla basterà utilizzare il comando `pacman`.
+
+```bash
+sudo pacman -S tmux
+```
+
+Per verificare che l'installazione sia andata a buon fine:
+
+```bash
+tmux -V
+```
+
+Il comando restituirà la versione installata.

+10. https://github.com/tmux/tmux/wiki
+
+## Primi passi con `tmux`
+
+Per eseguire `tmux` si dovrà semplicemente invocare il comando
+all'interno di una sessione di terminale.
+
+```bash
+tmux
+```
+
+È possibile staccare la sessione `tmux` premendo `Ctrl+B` seguito da
+`D`. `tmux` opera utilizzando una serie di scorciatoie da tastiera
+(keybindings) attivate premendo la combinazione "prefisso". Di
+default, il prefisso è `Ctrl+B`. Dopo di che, premere `D` per staccare
+dalla sessione corrente. La sessione continua ad eseguire in
+background anche dopo la disconnessione, permettendo di riprendere
+dove si è lasciati quando si è pronti a riconnettersi al server e
+riattaccarsi alla sessione esistente.
+
+`tmux` fornisce una serie di scorciatoie da tastiera per eseguire
+comandi rapidamente all'interno di una sessione `tmux`. Alcune delle
+più utili includono:
+
+- `Ctrl+B D` — Stacca dalla sessione corrente.
+- `Ctrl+B %` — Suddividi la finestra in due pannelli orizzontalmente.
+- `Ctrl+B "` — Suddividi la finestra in due pannelli verticalmente.
+- `Ctrl+B` seguito da una freccia (sinistra, destra, su, giù) — Sposta tra i pannelli.
+- `Ctrl+B X` — Chiudi il pannello.
+- `Ctrl+B C` — Crea una nuova finestra.
+- `Ctrl+B N` o `P` — Sposta alla finestra successiva o precedente.
+- `Ctrl+B 0` (1,2...) — Sposta a una finestra specifica per numero.
+- `Ctrl+B :` — Entra nella riga di comando per digitare
+  comandi. L'auto-completamento tramite tab è disponibile.
+- `Ctrl+B ?` — Visualizza tutte le scorciatoie da tastiera. Premere `Q` per uscire.
+- `Ctrl+B W` — Apre un pannello per navigare tra le finestre in più sessioni.
+
+### Esercizio
+
+Utilizza `tmux` per suddividere il terminale in due pannelli
+verticali. Nel pannello di sinistra apri uno script in Python
+utilizzando l'editor `nano`. Nel pannello di destra esegui il comando
+`htop`. Se `htop` non è presente nel sistema, procedi con la sua
+installazione attraverso il package manager `pacman`.
+
+## Configurazione di `tmux`
+
+Il file di configurazione di `tmux`, noto come `tmux.conf`, è un file
+di testo che permette agli utenti di personalizzare l'ambiente di
+lavoro di `tmux` secondo le proprie preferenze. Questo file può essere
+posizionato in due luoghi principali:
+
+- `~/.tmux.conf` per una configurazione specifica dell'utente corrente.
+- `/etc/tmux.conf` per una configurazione globale, applicabile a tutti gli utenti del sistema.
+
+Se il file `~/.tmux.conf` non esiste, può essere creato semplicemente
+eseguendo il comando `touch ~/.tmux.conf` nel terminale. Questo creerà
+un file di configurazione vuoto che può essere modificato per
+aggiungere le impostazioni desiderate.
+
+La configurazione di `tmux` può includere una vasta gamma di opzioni, tra cui:
+
+- Cambio del prefisso di comando predefinito.
+- Abilitazione della modalità mouse.
+- Impostazione di due prefissi.
+- Cambio del comportamento predefinito del server.
+- Inizio del conteggio dei numeri delle finestre e dei pannelli (Base-Index) a 1.
+- Modifica dello sfondo del pannello corrente.
+- ...
+
+Per esempio, per cambiare il prefisso di comando predefinito da
+`Ctrl+B` a `Ctrl+A`, si potrebbe aggiungere la seguente riga al file
+`tmux.conf`:
+
+```
+set-option -g prefix C-a
+```
+
+Dopo aver apportato modifiche al file di configurazione, è necessario
+ricaricarlo per applicare le nuove impostazioni. Questo può essere
+fatto eseguendo il comando `tmux source-file ~/.tmux.conf` dal
+terminale o utilizzando il comando `source-file ~/.tmux.conf` dalla
+modalità di comando di `tmux`. Per facilitare il processo, è possibile
+aggiungere un collegamento rapido nel file `tmux.conf` per ricaricare
+facilmente la configurazione:
+
+```
+bind r source-file ~/.tmux.conf \; display "Reloaded!"
+```
+
+Questo permette di ricaricare la configurazione premendo il prefisso
+seguito da `r`, visualizzando un messaggio di conferma.

+
+## Creazione di layout personalizzati
+
+Si supponga di voler creare un file di configurazione specifico per un
+progetto in cui il terminale viene diviso in tre parti: due colonne
+verticali di cui una a sua volta suddivisa orizzontalmente. In questo
+caso è possibile utilizzare uno script di configurazione
+personalizzato per `tmux`. Questo script può essere salvato in un file
+separato, ad esempio in `~/.config/tmux/split.conf`.
+
+```
+new -s splitted_session # crea una nuova sessione
+
+selectp -t 0 # seleziona il primo pannello
+splitw -h -p 50 # divide il pannello corrente orizzontalmente in due parti
+
+selectp -t 1 # seleziona il nuovo secondo pannello
+splitw -v -p 50 # divide il pannello corrente verticalmente in due parti
+selectp -t 0 # torna al primo pannello
+```
+
+Una volta creato il file di configurazione, occorrerà "eseguirlo" con
+
+```bash
+tmux source-file ~/.config/tmux/split.conf
+```
+
+### Esercizio
+
+Crea un file di configurazione `tmux` per produrre un layout con due
+righe di cui la prima suddivisa in due colonne secondo uno schema
+simile a quello riportato sotto.

+title: Cybersecurity con sistemi GNU/Linux
+subtitle: Programma del corso
+author: Andrea Fazzi
+data: 17.01.202
+urlcolor: blue
+---
+
+# Presentazione
+
+Il corso ha lo scopo di fornire una comprensione approfondita di Arch
+Linux, configurandolo opportunamente per utilizzarlo nel campo della
+sicurezza informatica e del penetration testing. Il corso copre una
+vasta gamma di argomenti, tra cui l'installazione di Arch Linux,
+l'analisi delle informazioni pubbliche e lo scanning di reti, le
+tecniche e le problematiche di sniffing, la sicurezza dei servizi come
+posta, DNS, web e SSH, l'hardening di Arch Linux, la prevenzione da
+tecniche di hacking comuni, e infine l'uso del bash scripting per la
+cybersecurity. Attraverso una combinazione di lezioni teoriche e
+pratiche, gli studenti avranno l'opportunità di acquisire competenze
+pratiche nel campo della sicurezza informatica.
+
+# Obiettivi
+
+* Fornire una comprensione delle caratteristiche e dei vantaggi di
+  Arch Linux.
+* Insegnare le tecniche di raccolta di informazioni e di scanning di
+  reti.
+* Spiegare le tecniche e le problematiche di sniffing e come
+  proteggersi.
+* Fornire una comprensione della sicurezza dei servizi di posta, DNS,
+  web e SSH.
+* Insegnare come rafforzare un sistema Arch Linux attraverso
+  l'hardening.
+* Fornire una comprensione delle tecniche di hacking comuni e come
+  prevenirle.
+* Insegnare l'uso del bash scripting per automatizzare le attività di
+  sicurezza e migliorare la cybersecurity.
+
+# Metodologie
+
+Le lezioni saranno dialogiche e partecipate. Gli studenti verranno
+condotti verso la costruzione delle conoscenze e competenze attraverso
+esempi, compiti di realtà, attività di problem solving.
+
+# Mezzi e strumenti
+
+Ciascuno studente avrà a disposizione un'installazione di Arch Linux
+GNU/Linux predisposta all'interno di una macchina virtuale.
+
+# Articolazione dei contenuti (40 ore)
+
+## Installazione di Arch Linux
+* Caratteristiche della distribuzione: Arch Linux è una distribuzione
+  Linux basata su Debian che è stata progettata specificamente per il
+  penetration testing e la sicurezza informatica. Include numerose
+  utility preinstallate per l'hacking etico, come Wireshark, Nmap,
+  Metasploit e altre.
+* Installazione su macchina laptop: l'installazione di Arch Linux su
+  un laptop comporta il download dell'immagine ISO dal sito ufficiale,
+  la creazione di una chiavetta USB avviabile, il boot da questa
+  chiavetta e infine la configurazione dell'installazione. Durante
+  l'installazione, è possibile selezionare le utility specifiche che
+  si desidera installare.
+
+## Analisi delle Informazioni pubbliche e network scanning
+* Tecniche di raccolta di informazioni: utilizzo di strumenti come
+  Whois, Nslookup e Dig per ottenere informazioni su un dominio o un
+  indirizzo IP.
+* Utilizzo di scanner di rete: utilizzo di strumenti come Nmap per
+  identificare i dispositivi sulla rete e le porte aperte su questi
+  dispositivi.
+* Analisi delle vulnerabilità: utilizzo di strumenti come Nessus o
+  OpenVAS per identificare le vulnerabilità nei dispositivi e nei
+  servizi di rete.
+* Metodi di mitigazione: implementazione di patch e aggiornamenti,
+  configurazione di firewall e IDS, utilizzo di VPN e crittografia.
+
+## Tecniche e problematiche di sniffing
+* Cos'è lo sniffing e come funziona: lo sniffing è una tecnica
+  utilizzata per intercettare e leggere il traffico di rete. Può
+  essere fatto utilizzando strumenti come Wireshark o Tcpdump.
+* Tecniche di sniffing: sniffing passivo, sniffing attivo, sniffing
+  diretto, sniffing indiretto.
+* Protezione da sniffing: utilizzo di protocolli crittografati come
+  HTTPS e SSH, configurazione di VPN, utilizzo di firewall e IDS.
+
+## Sicurezza dei servizi: posta, dns, web, ssh
+* Sicurezza del servizio di posta elettronica: configurazione di
+  protocolli sicuri come SMTPS, POP3S e IMAPS, implementazione di SPF,
+  DKIM e DMARC.
+* Sicurezza del servizio DNS: implementazione di DNSSEC,
+  configurazione di firewall per limitare le query DNS, monitoraggio
+  del traffico DNS per rilevare attività sospette.
+* Sicurezza del servizio web: configurazione di HTTPS, implementazione
+  di HSTS, utilizzo di WAF, attuazione di politiche di sicurezza del
+  contenuto.
+* Sicurezza del servizio SSH: disabilitazione dell'accesso root,
+  limitazione degli utenti che possono utilizzare SSH, configurazione
+  di chiavi SSH, utilizzo di Fail2ban.
+
+## Hardening di Arch Linux
+* Cosa significa hardening: l'hardening è il processo di rafforzamento
+  di un sistema informatico per ridurre la sua superficie di attacco.
+* Passaggi per l'hardening di un sistema Arch Linux: aggiornamento del
+  sistema, rimozione di servizi non necessari, configurazione di
+  firewall e IDS, implementazione di politiche di sicurezza avanzate.
+* Strumenti e tecniche per l'hardening: utilizzo di strumenti come
+  Lynis per l'hardening automatizzato, implementazione di SELinux o
+  AppArmor, configurazione di auditd.
+
+## Prevenzione da tecniche di hacking comuni
+* Tipi comuni di attacchi hacking: attacchi brute force, attacchi
+  DDoS, phishing, SQL injection, cross-site scripting.
+* Tecniche di prevenzione: utilizzo di password complesse, limitazione
+  del numero di tentativi di login, configurazione di firewall e IDS,
+  aggiornamento e patching del sistema e delle applicazioni,
+  formazione degli utenti.
+* Strumenti di monitoraggio e rilevamento degli attacchi: utilizzo di
+  strumenti come Snort, Wireshark, Syslog, ELK Stack.
+
+## Bash Scripting e Cybersecurity
+* Introduzione al bash scripting: cos'è lo scripting bash, perché è
+  utile, come scrivere script bash di base.
+* Utilizzo di script bash per automatizzare le attività di sicurezza:
+  creazione di script per l'automazione di attività come il
+  monitoraggio del sistema, la scansione di rete, l'hardening del
+  sistema.
+* Esempi di script bash utili per la cybersecurity: script per
+  l'analisi dei log, script per l'automazione di Nmap o Wireshark,
+  script per la generazione di report di sicurezza.
+* Best practices per la scrittura di script bash sicuri: utilizzo di
+  variabili non modificabili, controllo degli input, gestione degli
+  errori, limitazione dei privilegi.
+
+# Verifiche e valutazione
+
+Le verifiche saranno somministrate nella forma di test strutturati a
+risposta chiusa (4 risposte di cui solo una corretta). All'inizio del
+corso verrà proposto agli studenti un test per verificare le loro
+competenze iniziali. Al termine del corso verrà proposto una
+simulazione di test utile alla preparazione dell'esame conclusivo.
