ISE ISE BABY
NEW CAPABILITIES ON ISE 1.4
CENTRAL CAPABILITY TO MANAGE CERTIFICATES.- internal CA
MULTI DOMAIN AD INTEGRATION- EARLIER VERSIONS ONLY OPTION WAS TO CREATE TRUST BETWEEN DOMAINS OR USE LDAP IF TWP WAY TRUST IS NOT POSSIBLE.
CERTIFICATE SIGNING
generate a CSR and get it signed by MS CA server, you would also need to import root certificate to the trusted root certificates.
install the certificate on PAN (bind it to csr). Export the certificate and import it to secondary PAN.
once both nodes have wildcard certificate installed, registration can be initiated between them.
Once registration completes, need to look at profiling probes and select/deselect the ones deemed necessary.
AD INTEGRATION-
add a join point- for example, labminutes.com and sushil.local have a two way trust between them...adding labminutes.com in ISE as a join point will result in addition of both labminutes.com and
sushil.local
retrieve groups- can query both the domains between which two way trust exists.
test user authentication from ISE.
multiple users can be located in different domains.... ISE looks at password/successful authentication if account found in multiple domains.
MULTIPLE SCROPES are possible. - only run the query in certain domains
Identity source sequence -> define what identify sources ISE should look at.
WIRED 802.1 X -> USING EAP-TLS AND PEAP ( SELECTION IS DONE ON THE CLIENT WHETHER TO USE EAP-TLS OR PEAP, best if the settings are pushed through a GPO)
ISE would not co-relate machine auth and user auth - new version it works fine.
Non-domain computer - will use PEAP as no certificates installed - domain machines are expected to have machine and user certificates installed for dot1x to work correctly.
1. create NAD - NAD groups - for example - switch, wlc. switch configuration to use ISE for radius
2. ENABLE POLICY SETS - hierarchical policy - much better then previous versions. do not use default- create new policy set above default policy set
WIRED WIRED WIRED- 802.1x
conditions : device type equals switch (not sufficient to guarantee wired as switches support wireless / switch acting as wlc)
radius NAS-PORT-TYPE equals ETHERNET
cERTIFICATE AUTHENTICATION PROFILE - define what certificate parameter is used to authenticate user
CERT_CN -> WE NEED TO LOOKUP USER IN AD - so need to define an identity store
certificate attribute : subject-common name - this is where username is
need to ensure certificate based authentication is used in identity source sequence
AUTHENTICATION POLICY
allowed protocols - default
identity store
AUTHORIZATION policy
here is how it works
1. first machine authentication happens - once it is determined machine is part of domain computers, an acl is downloaded which allows access to AD; second round of authen - when user logs in so that
ise could authenticate user.
2. downloadable acl which will be sent to switch - AD_ONLY ..downloaded when machine auth is successful. ( dhcp, dns and IP to AD)
3. WIRED_PERMIT_ALL -> basic permit ip any any
AUTHORIZATION POLICY
FIRST POLICY
WIRED MACHINE - CONDITION EXTERNAL GROUPS PART OF DOMAIN COMPUTER
- Permissions -> the authorization profile with downloadable acl of wired_ad only.
SECOND POLICY
wired user - CONDITION EXTERNAL GROUPS PART OF DOMAIN user
second condition -> network access- wasmahcineauthenticated- true
Permission -> wired permit allowed
wiredautoconfig service needed for 801.x to run on the client machine.
WIRELESS WIRELESS WIRELESS 802.1x
setup wireless lan controller first- follow best practices
allow aaa override - for ise to push acls
nac status - radius nac
dhcp profiling and http profiling 0 checked
support for rfc 3576 - support change of authorization.
auth call station id type : ap mac address:ssid -> ise authorization profile will use ssid sent by ap for making authorization decisions.
access control list -> need to be conifgured on wlc itself.
ADD WLC AS NAD
CREATE A NEW POLICY SET - WLAN
CONSIITON - DEVICE TYPE ->WLC

option 1 -> ISE act as internal CA
option 2 -> AD act as CA- PAN act as intermediate CA -> PSN's act as subordinate CA.
1. for option 2, PAN needs to act as intermddiate CA . generate a csr and certificate usage will be for "ise internmediate ca", export it, use ad to sign it and use the template 'subordinat
certificate authority. Bind it to the csr.
export the certificate and import it on secondary node.-> setup a repository -> login to cli -> sh reporsitory -> application configyure ise
option -> export internal ca store
on node 2 -> import internal ca store
