\n\n\n\nExplication d\u00e9taill\u00e9e<\/h2>\n\n\n\nTypes de mots de passe<\/h3>\n\n\n\n
enable password
Ancien m\u00e9canisme. Mot de passe stock\u00e9 en clair ou faiblement chiffr\u00e9.
\u00c0 \u00e9viter.<\/p>\n\n\n\n
enable secret
Mot de passe du mode privil\u00e9gi\u00e9.
Stock\u00e9 sous forme chiffr\u00e9e (hash).
\u00c0 utiliser syst\u00e9matiquement.<\/p>\n\n\n\n
\n\n\n\nComptes locaux<\/h3>\n\n\n\n
username
Permet de cr\u00e9er des utilisateurs locaux.<\/p>\n\n\n\n
Exemple :<\/p>\n\n\n\n
\n- admin \u2192 acc\u00e8s complet (niveau 15)<\/li>\n\n\n\n
- user \u2192 acc\u00e8s limit\u00e9<\/li>\n<\/ul>\n\n\n\n
Le niveau de privil\u00e8ge d\u00e9termine les commandes autoris\u00e9es.<\/p>\n\n\n\n
\n\n\n\nNiveaux de privil\u00e8ge<\/h3>\n\n\n\n
0 \u00e0 15<\/p>\n\n\n\n
\n- 1 \u2192 utilisateur standard<\/li>\n\n\n\n
- 15 \u2192 administrateur complet<\/li>\n<\/ul>\n\n\n\n
Permet de segmenter les droits.<\/p>\n\n\n\n
\n\n\n\nAuthentification locale<\/h3>\n\n\n\n
login local
Force l\u2019utilisation des comptes cr\u00e9\u00e9s avec username<\/code>.<\/p>\n\n\n\nSans cette commande, le mot de passe de ligne peut \u00eatre utilis\u00e9, ce qui est moins s\u00e9curis\u00e9.<\/p>\n\n\n\n
\n\n\n\nChiffrement<\/h3>\n\n\n\n
service password-encryption
Chiffre les mots de passe de configuration (type 7).<\/p>\n\n\n\n
Attention : ce n\u2019est pas un chiffrement fort, mais cela \u00e9vite le stockage en clair.<\/p>\n\n\n\n
\n\n\n\nBonnes pratiques<\/h3>\n\n\n\n\n- utiliser uniquement
enable secret<\/code><\/li>\n\n\n\n- cr\u00e9er des comptes nominatifs<\/li>\n\n\n\n
- \u00e9viter les comptes partag\u00e9s<\/li>\n\n\n\n
- d\u00e9finir des mots de passe complexes<\/li>\n\n\n\n
- limiter les privil\u00e8ges<\/li>\n\n\n\n
- utiliser SSH avec authentification locale<\/li>\n\n\n\n
- supprimer les comptes inutilis\u00e9s<\/li>\n<\/ul>\n\n\n\n
\n\n\n\nPoints cl\u00e9s<\/h2>\n\n\n\n\n- enable secret obligatoire<\/li>\n\n\n\n
- comptes locaux recommand\u00e9s<\/li>\n\n\n\n
- niveaux de privil\u00e8ges \u00e0 utiliser<\/li>\n\n\n\n
- login local pour s\u00e9curiser les acc\u00e8s<\/li>\n\n\n\n
- \u00e9viter enable password<\/li>\n\n\n\n
- chiffrement activ\u00e9<\/li>\n<\/ul>\n\n\n\n
\n\n\n\nSuite logique<\/h2>\n\n\n\n
Pour aller plus loin :<\/p>\n\n\n\n
\n- mise en place AAA (Radius \/ Tacacs+)<\/li>\n\n\n\n
- gestion centralis\u00e9e des comptes<\/li>\n\n\n\n
- journalisation des connexions<\/li>\n\n\n\n

\n\n\n\nExplication d\u00e9taill\u00e9e<\/h2>\n\n\n\nTypes de mots de passe<\/h3>\n\n\n\n
enable password
Ancien m\u00e9canisme. Mot de passe stock\u00e9 en clair ou faiblement chiffr\u00e9.
\u00c0 \u00e9viter.<\/p>\n\n\n\n
enable secret
Mot de passe du mode privil\u00e9gi\u00e9.
Stock\u00e9 sous forme chiffr\u00e9e (hash).
\u00c0 utiliser syst\u00e9matiquement.<\/p>\n\n\n\n
\n\n\n\nComptes locaux<\/h3>\n\n\n\n
username
Permet de cr\u00e9er des utilisateurs locaux.<\/p>\n\n\n\n
Exemple :<\/p>\n\n\n\n
\n- admin \u2192 acc\u00e8s complet (niveau 15)<\/li>\n\n\n\n
- user \u2192 acc\u00e8s limit\u00e9<\/li>\n<\/ul>\n\n\n\n
Le niveau de privil\u00e8ge d\u00e9termine les commandes autoris\u00e9es.<\/p>\n\n\n\n
\n\n\n\nNiveaux de privil\u00e8ge<\/h3>\n\n\n\n
0 \u00e0 15<\/p>\n\n\n\n
\n- 1 \u2192 utilisateur standard<\/li>\n\n\n\n
- 15 \u2192 administrateur complet<\/li>\n<\/ul>\n\n\n\n
Permet de segmenter les droits.<\/p>\n\n\n\n
\n\n\n\nAuthentification locale<\/h3>\n\n\n\n
login local
Force l\u2019utilisation des comptes cr\u00e9\u00e9s avec username<\/code>.<\/p>\n\n\n\nSans cette commande, le mot de passe de ligne peut \u00eatre utilis\u00e9, ce qui est moins s\u00e9curis\u00e9.<\/p>\n\n\n\n
\n\n\n\nChiffrement<\/h3>\n\n\n\n
service password-encryption
Chiffre les mots de passe de configuration (type 7).<\/p>\n\n\n\n
Attention : ce n\u2019est pas un chiffrement fort, mais cela \u00e9vite le stockage en clair.<\/p>\n\n\n\n
\n\n\n\nBonnes pratiques<\/h3>\n\n\n\n\n- utiliser uniquement
enable secret<\/code><\/li>\n\n\n\n- cr\u00e9er des comptes nominatifs<\/li>\n\n\n\n
- \u00e9viter les comptes partag\u00e9s<\/li>\n\n\n\n
- d\u00e9finir des mots de passe complexes<\/li>\n\n\n\n
- limiter les privil\u00e8ges<\/li>\n\n\n\n
- utiliser SSH avec authentification locale<\/li>\n\n\n\n
- supprimer les comptes inutilis\u00e9s<\/li>\n<\/ul>\n\n\n\n
\n\n\n\nPoints cl\u00e9s<\/h2>\n\n\n\n\n- enable secret obligatoire<\/li>\n\n\n\n
- comptes locaux recommand\u00e9s<\/li>\n\n\n\n
- niveaux de privil\u00e8ges \u00e0 utiliser<\/li>\n\n\n\n
- login local pour s\u00e9curiser les acc\u00e8s<\/li>\n\n\n\n
- \u00e9viter enable password<\/li>\n\n\n\n
- chiffrement activ\u00e9<\/li>\n<\/ul>\n\n\n\n
\n\n\n\nSuite logique<\/h2>\n\n\n\n
Pour aller plus loin :<\/p>\n\n\n\n
\n- mise en place AAA (Radius \/ Tacacs+)<\/li>\n\n\n\n
- gestion centralis\u00e9e des comptes<\/li>\n\n\n\n
