Getting the clients MAC address over WiFi is trivial to do and an attacker could then just spoof I have moved to WPA2-Enterprise encryption on my network with server 2008R2 acting as the Radius server and some off the shelf Asus routers. MAC Address Authentication to the Network The access point relays the wireless client device's MAC address to a RADIUS server on your network, and the server checks the address against a list of allowed MAC addresses. Because intruders can create counterfeit MAC addresses, MAC-based authentication is less secure than EAP authentication.
Networking uses the Identity service as the default authenticationservice. When the Identity service is enabled, users who submit requeststo the Networking service must provide an authentication token inX-Auth-Token request header. Users obtain this token byauthenticating with the Identity service endpoint. For more informationabout authentication with the Identity service, see OpenStack Identityservice API v3Reference.When the Identity service is enabled, it is not mandatory to specify theproject ID for resources in create requests because the project ID isderived from the authentication token.
The default authorization settings only allow administrative usersto create resources on behalf of a different project. Networking usesinformation received from Identity to authorize user requests.Networking handles two kind of authorization policies:
Operation-based policies specify access criteria for specificoperations, possibly with fine-grained control over specificattributes.
Resource-based policies specify whether access to specificresource is granted or not according to the permissions configuredfor the resource (currently available only for the network resource).The actual authorization policies enforced in Networking might varyfrom deployment to deployment.
Locating the MAC/Physical Address of an Amazon Dot, Echo, FireTV or Tap using the Alexa app Step 1: Download the Alexa app from the Apple App store or Google Play store. You can search for Alexa on either app store or use the QR codes below. Apple App Store Google Play Store. Call them and provide the wifi MAC address of the ftv. They'll manually log you in past the captive portal, and you'll have regular internet access. https://newlineassets892.weebly.com/aquarelo-1-0-3-improve-your-color-workflow.html. Since this is the second time this has been mentioned recently, it may be worth sideloading a browser like Firefox for future situations, where the built-in support is insufficient. If you’re seeing authentication failures from 127.0.0.1 and you’re using the nmap device tracker, you should exclude the Home Assistant IP from being scanned. Bearer token warnings. Under the new authentication system you’ll see the following warning logged when the legacy API password is supplied, but not configured in Home Assistant.
The policy engine reads entries from the policy.json file. Theactual location of this file might vary from distribution todistribution. Entries can be updated while the system is running, and noservice restart is required. Every time the policy file is updated, thepolicies are automatically reloaded. Currently the only way of updatingsuch policies is to edit the policy file. In this section, the termspolicy and rule refer to objects that are specified in the same wayin the policy file. There are no syntax differences between a rule and apolicy. A policy is something that is matched directly from theNetworking policy engine. A rule is an element in a policy, which isevaluated. For instance in 'create_subnet':'rule:admin_or_network_owner', create_subnet is apolicy, and admin_or_network_owner is a rule.
Policies are triggered by the Networking policy engine whenever one ofthem matches a Networking API operation or a specific attribute beingused in a given operation. For instance the create_subnet policy istriggered every time a POST/v2.0/subnets request is sent to theNetworking server; on the other hand create_network:shared istriggered every time the shared attribute is explicitly specified (andset to a value different from its default) in a POST/v2.0/networksrequest. It is also worth mentioning that policies can also be relatedto specific API extensions; for instanceextension:provider_network:set is triggered if the attributesdefined by the Provider Network extensions are specified in an APIrequest.
An authorization policy can be composed by one or more rules. If morerules are specified then the evaluation policy succeeds if any of therules evaluates successfully; if an API operation matches multiplepolicies, then all the policies must evaluate successfully. Also,authorization rules are recursive. Once a rule is matched, the rule(s)can be resolved to another rule, until a terminal rule is reached.
The Networking policy engine currently defines the following kinds ofterminal rules:
Role-based rules evaluate successfully if the user who submitsthe request has the specified role. For instance 'role:admin' issuccessful if the user who submits the request is an administrator.
3dweather 3 4. Field-based rules evaluate successfully if a field of theresource specified in the current request matches a specific value.For instance 'field:networks:shared=True' is successful if theshared attribute of the network resource is set to true.
Generic rules compare an attribute in the resource with anattribute extracted from the user’s security credentials andevaluates successfully if the comparison is successful. For instance'tenant_id:%(tenant_id)s' is successful if the project identifierin the resource is equal to the project identifier of the usersubmitting the request.
This extract is from the default policy.json file: Mac app store list.
A rule that evaluates successfully if the current user is anadministrator or the owner of the resource specified in the request(project identifier is equal).
The default policy that is always evaluated if an API operation doesnot match any of the policies in policy.json.
This policy evaluates successfully if either admin_or_owner, orshared evaluates successfully.
This policy restricts the ability to manipulate the sharedattribute for a network to administrators only.
This policy restricts the ability to manipulate the mac_addressattribute for a port only to administrators and the owner of thenetwork where the port is attached.
In some cases, some operations are restricted to administrators only.This example shows you how to modify a policy file to permit project todefine networks, see their resources, and permit administrative users toperform all other operations:
