TACACS+ Authentication for Routers, Switches & Network Devices

What is TACACS/TACACS+ Authentication?

TACACS, which stands for Terminal Access Controller Access-Control System, is a network protocol that was developed by Cisco. TACACS+ is an improved version of the original TACACS protocol, which is now popularly used in the industry for Authentication, Authorization, and Accounting (AAA) in network security.

TACACS/TACACS+ Authentication controls user access to devices like routers, NAS, and switches, separating authentication and allowing fine-grained access control. With encryption and support for command authorization, it significantly improves the security of enterprise networks.




Operations Supported by TACACS+ Authentication

TACACS+ AAA separates authentication, authorization, and accounting, giving you centralized control over network administrator access and activity.

Authentication

Verify administrator identities before granting access to routers, switches, and other network devices through supported TACACS+ authentication methods.


  • Support ASCII, PAP, and CHAP authentication
  • Add TOTP, push, or out-of-band MFA
  • Authenticate against existing enterprise identity stores

Authorization

Control what authenticated administrators can access and execute using privilege levels, AV pairs, and granular command-level authorization policies.


  • Assign privilege levels from 0–15
  • Configure AV pairs and custom attributes
  • Allow or deny commands per privilege

Accounting

Record administrator sessions and commands with detailed TACACS+ accounting data for auditing, monitoring, investigation, and security operations.


  • Capture Start, Stop, and Watchdog records
  • Record commands, timestamps, and session IDs
  • Track task IDs and source/framed IPs

Secure Network Access With miniOrange TACACS+ Authentication

Bring administrator authentication, access policies, MFA, and network activity controls together across your infrastructure.

Authenticate administrators consistently across routers, switches, firewalls, and other network devices through a dedicated TACACS+ server.

Define privilege levels, AV pairs, and command permissions to determine exactly what each administrator can view or execute.

Strengthen TACACS+ authentication with an additional verification step using TOTP, push, or out-of-band authentication methods.

Use Active Directory and LDAP identities and groups to authenticate administrators without creating a separate identity store.

Apply TACACS+ authentication across Cisco, Juniper, Huawei, Nokia, Fortinet, and other supported network devices.

Expose authorization-related events through supported APIs for monitoring, reporting, security workflows, and integration with external systems.

Add an MFA Layer to TACACS+ Authentication

Add an independent verification layer to TACACS+ authentication for stronger protection of network administrator access.

  • Verify administrators beyond passwords alone
  • Support 15+ authentication methods
  • Enable TOTP, push, and OTP
  • Use passkeys and FIDO2 security keys
  • Support hardware tokens and smart cards
  • Enable biometric and adaptive authentication

How miniOrange Handles TACACS+ Authentication

miniOrange connects your network devices, identity sources, MFA, and access policies into one administrator authentication flow.

1
Step 01

Administrator Requests Network Access

An administrator enters their credentials on a Cisco, Juniper, Nokia, or other supported network device to start a session.

2
Step 02

miniOrange Validates the Identity

The network device sends the TACACS+ request to miniOrange, which verifies the administrator against Active Directory, LDAP, or a configured database.

3
Step 03

miniOrange Performs MFA Verification

When MFA is enabled, miniOrange triggers an additional verification step using TOTP, push, or out-of-band authentication before access is authorized.

4
Step 04

miniOrange Evaluates Access Policies

The TACACS+ server determines the administrator's privilege level, AV pairs, and permitted commands based on configured roles and authorization policies.

5
Step 05

Access Is Granted and Accounted

miniOrange returns the authorization response to the network device, which grants the permitted access, while TACACS+ accounting records sessions and commands.

How miniOrange Handles TACACS+ Authentication

Why Network Teams Choose miniOrange for TACACS+

Get an enterprise-ready TACACS+ solution designed to simplify network access management while fitting the operational realities of modern IT environments.

Simplify Access Administration

Manage TACACS+ access through a centralized administrative experience instead of maintaining authentication configurations across individual network devices.

Modernize Legacy Infrastructure

Move away from outdated TACACS+ infrastructure while retaining the network devices and identity environment your teams already depend on.

Connect Security Workflows

Extend TACACS+ access data into broader security operations to support monitoring, investigation, and response workflows.

Adapt Without Rebuilding

Update access policies as teams, responsibilities, devices, and network environments change without rebuilding the underlying authentication architecture.

Your Network Deserves a Smarter Access Model

Replace fragmented administrator access with a deliberate approach to authentication, privilege, and accountability.

More FAQ

How is TACACS+ different from RADIUS?

TACACS+ separates Authentication, Authorization, and Accounting into three distinct operations and encrypts the full packet. RADIUS only encrypts the password and bundles all three operations together. TACACS+ also uses TCP for reliable connections; RADIUS uses UDP. If you need command-level control over network devices, TACACS+ is the right choice.

What devices support TACACS+?

Most big network devices from companies like Cisco, Juniper, Nokia, Huawei, and Fortinet support TACACS+ for secure access control.

Why should I use TACACS+ in my network?

TACACS+ gives you detailed control over who can do what, keeps communication secure, and logs user activities well. It's great for protecting important systems and following rules like HIPAA, PCI-DSS, or ISO 27001.

What deployment options does miniOrange TACACS+ support?

miniOrange TACACS+ is available as Cloud (IDaaS), On-Premise (including air-gapped environments), and Hybrid. You choose the deployment that fits your infrastructure — no forced cloud migration.

How does TACACS+ improve compliance and auditing?

TACACS+ records what each user does, including all commands they run. This detailed logging helps with investigations, audit trails, and meeting compliance rules.

Can I export TACACS+ authorization logs to my SIEM?

Yes. miniOrange streams all TACACS+ authentication and authorization events to your SIEM in real time via a unified auditing framework. Supported platforms include Splunk, Microsoft Sentinel, IBM QRadar, and any syslog-compatible SIEM.

Can I query TACACS+ authorization events via API?

Yes. The TACACS+ authorization event API lets you pull privilege grant and deny records into your own dashboards, SOAR tools, or compliance reporting workflows programmatically — no manual log exports needed.

Does miniOrange TACACS+ support command authorization?

Yes. You can define which commands each user or group is allowed to run on each device. This gives you granular control beyond basic login access — critical for compliance with PCI-DSS and HIPAA network security requirements.
