This document will describe best practices that network administrators can use to reduce the risk of malicious code being installed on Cisco IOS devices. This attack scenario could occur on any device that uses a form of software, given a proper set of circumstances.

It may be possible for an attacker to insert malicious code into a Cisco IOS software image and load it onto a Cisco device that supports that image. Further details are documented in the Cisco Security Vulnerability Policy. Depending on severity, security issues in Cisco IOS software are communicated to customers using Security Advisories, Security Responses, or Cisco bug release notes. The integrity of the software used on Cisco IOS devices, in this case Cisco IOS software, is also important to device security. The document entitled Cisco Guide to Harden Cisco IOS Devices represents one collection of those best practices. The security configuration of a device, specifically in relation to device security, is conveyed using documented best practices. The security of Cisco IOS devices consists of multiple factors, including physical and logical access to the device, configuration of the device, and the inherent security of the software being used.

Avi Vantage TACACS+ auth profile is configured the same way as that for ISE or ACS.Leverage Authentication, Authorization, and Accounting. Conceptually, users are assigned to groups and groups have request and response attributes. 
This is mostly relevant in development or testing environments.
TAC_PLUS server is a much simpler alternative to ISE/ACS. To know more, refer to User Account Roles. Avi Vantage TACACS+ authorization role and tenant mapping configured to assign different roles based on TACACS+ attribute value. To know more, refer to TACACS+ Authentication In the case of an ACS server, service=avishell is required for user authorization while in the case of an ISE server, service=avishell is known to cause authorization failure. Authorization attributes from a TACACS+ server can be used to map Avi Vantage users to various roles and tenants. The “service” attribute is generally required to identify and authorize a Vantage user. The Avi Vantage TACACS+ auth profile should be configured with the same shared secret that was assigned to the device in ISE. ISE device policy sets default condition updated to assign different shell profiles based on group membership. ISE requires shell profiles and TACACS+ profiles configured. ISE server should recognize all Avi Vantage Controller cluster nodes as valid Network Devices. ISE Authorization conditions added for Users in the AD groups. ISE LDAP settings used to fetch LDAP groups in order to use them for Authorization conditions. The ISE server is generally configured with external Identity Sources (in this case OpenLDAP). Given below are steps involved in setting up an ISE TACACS+ server as a remote authentication and authorization system for Avi Vantage. Cisco ISE functions as a policy decision point and enables enterprises to ensure compliance, enhance infrastructure security, and streamline service operations. Cisco ISE is a security policy management platform that provides secure access to network resources.
