# Das kleine 1x1 der Computersicherheit
|
||||
|
||||
## System-Setup
|
||||
|
||||
### Grundlagen
|
||||
|
||||
* Jeder Desktop oder Laptop ist ein Computer und jeder Computer kann ein Server werden
|
||||
(General Purpose Computing)
|
||||
* Abhängig ist das von der installierten und laufenden Software.
|
||||
* Scope: persönliche Rechentechnik
|
||||
* Desktop-PCs
|
||||
* Laptops
|
||||
* Smartphones
|
||||
* Tablets
|
||||
* Heimserver (z.B.: NAS)
|
||||
* Alles, was man euch wegtragen kann, gehört verschlüsselt.
|
||||
* Das gilt insbesondere Laptops, da mobil.
|
||||
|
||||
#### Basiselemente laut BSI
|
||||
|
||||
* Updates
|
||||
* Passwörter
|
||||
* Passwortmanager
|
||||
* 2FA
|
||||
* Virenschutz
|
||||
* Firewall
|
||||
|
||||
### Festplattenverschlüsselung/Encryption
|
||||
|
||||
* Klassischewrweise in der Linux-Welt verbreitet: LUKS
|
||||
* Die meisten Linux-Distribution bieten Festplattenverschlüsselung im Installer an (z.B.: Fedora,
|
||||
Debian, OpenSUSE)
|
||||
|
||||
### Passwortmanager
|
||||
|
||||
* Das beste Passwort ist das, das man selbst nicht kennt
|
||||
* Online Passwortmanager **TODO: Evaluierung: funktionieren die auch offline?**
|
||||
* Online-Dienste:
|
||||
* 1Password
|
||||
* BitWarden
|
||||
* Selfhosted:
|
||||
* Vaultwarden (BitWarden reimplementation)
|
||||
* Offline
|
||||
* Datenbank kann, wenn verschlüsselt, über Sync-Dienste (insbesondere selfhosted) zwischen
|
||||
Geräten geteilt werden
|
||||
|
||||
### Datensicherung/Backups
|
||||
|
||||
* Macht Backups!
|
||||
* verschlüsseln! (s. o.)
|
||||
* mehrere Mechanismen:
|
||||
* externe Festplatte/USB-Stick als Speicher
|
||||
* Netzwerkbasiert (Heimserver oder entfernter Server)
|
||||
* Cloudbasierte Speicher sind mit Vorsicht zu genießen (Verschlüsseln!)
|
||||
* Tarsnap (Motto: Online backups fpr the truly paranoid)
|
||||
* SpiderOak
|
||||
* Selfhosted/Managed Nextcloud
|
||||
* praktische Beispiele mit GUI (Duplicati, Déjà Dup, TimeShift)
|
||||
|
||||
### Datensicherheit/Updates
|
||||
|
||||
* Macht Updates!
|
||||
* Wenn ihr nicht aufgrund von $Spezialsoftware für den täglichen Einsatz auf Windows gebunden seit,
|
||||
gibt es keinen triftigen Grund noch Windows zu benutzen.
|
||||
* Separation fo Concerns betreiben: $Spezialsoftware bekommt ihren eigenen Rechner,
|
||||
der explizit nur das tut. Alles andere zieht auf ein Linux um.
|
||||
|
||||
### Virenschtz
|
||||
|
||||
* Email-Anhänge mit Bedacht öffnen
|
||||
* ClamAV, wenn unbedingt nötig
|
||||
|
||||
### Firewall
|
||||
|
||||
* Firewall bei Desktop-Linux kaum von Bedeutung
|
||||
* Wer darauf Wert legt, finden Distributionsspezifische Anleitungen im zuhauf im Internet
|
||||
* Sobald ihr aber öffentlich erreichbare Server betreibt (Nginx, Apache, OpenSSH-Server, …) ist
|
||||
eine Firewall nötig.
|
||||
|
||||
## Endanwendungen
|
||||
|
||||
### Email
|
||||
|
||||
* Email ist ein altes Protokol, dass aus einer anderen Zeit stammt
|
||||
* GnuPG
|
||||
* Große Anhänge lieber auf Cloudspeicher laden und Links per Email verschicken.
|
||||
|
||||
### Email- und Kalender-Client
|
||||
|
||||
* Thunderbird
|
||||
|
||||
### Chat
|
||||
|
||||
* Pidgin (Multi-Protocol)
|
||||
* Gajim/Conversations (XMPP)
|
||||
* OMEMO is a must
|
||||
|
||||
### Browser
|
||||
|
||||
* Chrome -> Chromium/Iridium
|
||||
|
||||
|
||||
### Software-Alternativen finden
|
||||
|
||||
* [AlternativeTo](https://alternativeto.net)
|
||||
* [Prism Break](https://prism-break.org/en/) -- Leider etwas veraltet
|
||||
|
||||
## Online-Dienste
|
||||
|
||||
### Suchmaschinene
|
||||
|
||||
* Nein: Google, Yahoo, Bing -> DuckDuckGo, ixQuick, yacy
|
||||
|
||||
### Code Hosting
|
||||
|
||||
* Nein: GitHub -> GitLab, CodeBerg
|
||||
|
||||
### Online Office
|
||||
|
||||
* Google Docs -> Collabora online (In NextCloud inkludierbar)
|
||||
|
||||
### VPN
|
||||
