Start this road

AAA, 802.1X & LDAP

Logging in to routers, ports and servers centrally.

  1. 01 AAA with RADIUS: who logs in to the router, what they may do, and a log of it Router AAA: RADIUS decides who logs in, what they may run, and records it. Pro
  2. 02 802.1X and RADIUS: logging in to a switch port Unlock a switch port by logging in with 802.1X against RADIUS. Pro
  3. 03 LDAP: one directory for every login Use one LDAP login on every server, and remove it in one place. Pro

Kerberos, SSO, MFA & zero trust

Tickets, single sign-on, second factors and zero trust.

  1. 01 Kerberos: one login, tickets for everything Get a Kerberos ticket once, then log in to services with no password. Pro
  2. 02 Two-factor SSH with a one-time code Add SSH 2FA: a one-time code as well as the password for every login. Pro
  3. 03 Single sign-on: one login, many services Sign in once with OpenID Connect and SAML, and see how the portal trusts it. Pro
  4. 04 Zero trust with mutual TLS Let only devices with a valid client certificate reach each service. Pro
