Guide to configuring a Virtual Private Network using Cisco
Cisco ASA 5500 and 5500-X security appliances are certified under CESG’s Commercial Product Assurance (CPA) scheme at Foundation Grade for IPsec VPN Gateway This guide details the steps required to configure a Virtual Private Network (VPN) using Cisco ASA that conforms to the interim and end-state IPsec profiles and CPA
Cisco ASA Configuration Guidance

Initially an ASA does not have a password configured; therefore when prompted leave the enable password prompt blank and press Enter The ASA date and time should be set either manually or by using Network Time Protocol (NTP) To set the date and time use the clock setprivileged EXEC command
Does Cisco ASA 5505 support IPsec?
- This feature is disabled by default. With the exception of the home zone on the Cisco ASA 5505, the security appliance can simultaneously support standard IPsec, IPsec over TCP, NAT-T, and IPsec over UDP, depending on the client with which it is exchanging data.
What are Cisco type 6 passwords?
- Cisco Type 6 passwords, for example, allow for secure, encrypted storage of plaintext passwords on the device. When configuration files are not properly protected, Cisco devices that are configured to use a weak password protection algorithm do not adequately secure the credentials.
What is the importance of password security for Cisco network devices?
- The importance of implementing password security for Cisco network devices will greatly decrease the chances of any network being compromised. If one is mindful of the hash and encryption algorithms that are available within Cisco devices, more secure configurations can be set to prevent password exposure as follows: ?Use password Type 8.
How do IPsec SAs work?
- IPsec SAs use a derived, shared, secret key. The key is an integral part of the SA; they time out together to require the key to refresh. Each SA has two lifetimes: “timed” and “traffic-volume.” An SA expires after the respective lifetime and negotiations begin for a new one.

Introduction
This document describes how to configure TACACS+ Authentication and Command Authorization on Cisco Adaptive Security Appliance (ASA) with Identity Service Engine (ISE) 2.0 and later. ISE uses local identity store to store resources such as users, groups, and endpoints.Prerequisites
Requirements
Cisco recommends that you have knowledge of these topics:ASA Firewall is fully operationall
Connectivity between ASA and ISEl
ISE Server is bootstrappedl
Components Used
The information in this document is based on these software and hardware versions:Cisco Identity Service Engine 2.0l
Cisco ASA Software Release 9.5(1)l
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.Refer to
Cisco Technical Tips Conventions
for more information on document conventions.Configure
The aim of the configuration is to:
Authenticate ssh user via Internal Identity Storel Authorize ssh user so it will be placed into privileged EXEC mode after the loginl Check and send every executed command to ISE for verificationlNetwork Diagram
Configurations

Two command sets are configured. First
PermitAllCommands
for the administrator user which allow all commands on the device. SecondPermitPingShowCommands
for user user which allow only show and ping commands.1. Navigate to
Work Centers > Device Administration > Policy Results > TACACS Command Sets. Click Add.Provide the Name

selectPermit any command that is
not listed below checkbox and clickSubmit.
2. Navigate to Work Centers > Device Administration > Policy Results > TACACS Command
Sets. Click Add.Provide the Name
PermitPingShowCommands,
click Add and permit show, ping and exit commands. By default if Arguments are left blank, all arguments are included. ClickSubmit.
Configuring TACACS Profile
Single TACACS Profile will be configured. Actual command enforcement will be done via command sets. Navigate to Work Centers > Device Administration > Policy Results >TACACS Profiles.
Click Add.Provide Name
ShellProfile,
selectDefault Privilege
checkbox and enter the value of 15. ClickSubmit
Configuring TACACS Authorization Policy
Authentication Policy by default points to All_User_ID_Stores, which includes the Local Store as well, so it is left unchanged.Navigate to
Work Centers > Device Administration > Policy Sets > Default > AuthorizationPolicy > Edit > Insert New Rule Above.

membership. Configure the Cisco ASA Firewall for Authentication and Authorization1. Create a local user with full privilege for fallback with the username command as shown here
ciscoasa(config)# username cisco password cisco privilege 152. Define TACACS server ISE, specify interface, protocol ip address, and
tacacs key. ciscoasa(config)# username cisco password cisco privilege 15 Note : Server key should match the one define on ISE Server earlier.3. Test the TACACS server reachability with the test
aaa command as shown. ciscoasa# test aaa authentication ISE host 10.48.17.88 username administrator Krakow123 INFO: Attempting Authentication test to IP address <10.48.17.88> (timeout: 12 seconds)INFO: Authentication Successful
The output of the previous command shows that the TACACS server is reachable and the user has been successfully authenticated.4. Configure authentication for ssh, exec authorization and command authorizations as shown
below. With aaa authorization exec authentication-server auto-enable you will be placed inquotesdbs_dbs14.pdfusesText_20[PDF] password policy example
