Creating Firesight IPS policies

I need help for creating rule asa firesight ips.

By default, it is a 'discovery network' under access control. It works fine, I see connection events.

Now, I want to do full-fledged IPS. How do I do that?

On Firesight, IPS-> policy, create a new policy, I'm doing here had to be defined, rules and categories?

Please see the presentation of Cisco Live session BRKSEC-2018 of Cisco Live WE earlier this year. It is a free download from ciscolive365.com.

He did a great job to specify what policies are necessary for effective deployment of firepower and how to create them.

  • Config Service IPS 5520 policy assistance

    I have a 5520 running 7.2 (4) (Routed, unique context) with a SSM20 running 1.0000 E2.

    I'm struggling a bit with DFS configuration on my 5520. I created 2 service policies, one applied to a DMZ interface and configured as 'in-line '. Others applied within the interface and set up "promiscuous" (until I get it tuned).

    It seems that there is no way (about 7.2) to run each service its own virtual sensor on the SSM20 strategy. That's why I'm fighting a little trying to determine what political Service sends the traffic that triggers a particular event. Is there something in the SSM event log that identifies which Service policy sent traffic to the virtual sensor?

    Thanks in advance!

    David

    The ASA does not say the SSM what policy sent the package, so that the SSM cannot declare what policy sent him. Only if we monitor the promiscuity or inline (and in the case of 8.0 what context it comes and which virtual sensor to use).

    Other things that might help.

    Look at the addresses of alerts.

    If the source address is an address DMZ, then probably the DMZ policy.

    If the source address is an address to the inside, then probably domestic politics.

    If the source address is an address from the outside, then watch the address of destination.

    If the destination is an address DMZ, then probably the DMZ policy.

    If the desintation is an address to the inside, then probably domestic politics.

    Why?

    In the case of TCP SYN packet will determine what policy will affect the rest of the packages.

    And it's the first corresponding ips policy that will determine the type of monitoring.

    If a packet coming FROM the DMZ to Internet SYN will be first checked by the DMZ policy. If the DMZ policy is, then it will be inline monitored (by the DMZ policy).

    Similarly a SYN from the DMZ TO the Interior package will check first of all by the DMZ policy, then it will it be controlled by domestic politics. If the DMZ policy match then the SYN and the rest of the packets for the connection will be guarded inline. If corresponds to the policy of the DMZ, then domestic politics will be always checked, but it is the policy of the DMZ that determines the promiscuity or inline because it's the first policy matched. If the DMZ policy does NOT match the SYN packet, but is domestic politics, then the connection will be histocompatibility by domestic politics.

    Conversely, however, a package SYN FROM inside the DMZ will be firt compared to domestic politics.

    Inside corresponding to the first policy would cause the connection to monitor histocompatibility. Politics of the DMZ would be verified, as well, but with the domestic policy corresponding to the first, it will track promisuous.

    If domestic politics does NOT match would be the a political DMZ was filled with online monitoring.

    At least that's how I think that it worked in 7.2. The above, this is how it works in 8.0 when we tested with virtual probes and so I guess it worked that way in 7.2 as well.

    In your alerts above. The first alert was 'Actions droppedPacket + deniedFlow + tcpOneWayResetSent' Deny/Drop actions cannot run in Inline mode, so it must come from the DMZ policy.

    The second alert was 'Actions denyPacketRequestedNotPerformed + denyFlowRequestedNotPerformed' and 'NotPerformed"to Deny/Drop actions usually only happens with the Promiscuous mode. So, he had to be domestic policy.

  • Policies for approval 11g IOM - approval rule to check the Connection Manager

    Hello

    I have a requirement in which if the applicant of a resource is a Manager, while demand should automatically be approved. However if the applicant is one person other than the owner, then it should be assigned to the Manager for approval. Is it possible to do this verification in the approval rule?

    My idea was to create two trust policies for the same resource with a single policy with auto approve activated if the connection applicant is same as connection of eating of the beneficiary and other policies with the default approval process BeneficiaryManager if the connection of the applicant is different from the connection of the beneficiary. I don't know if the approval rule can be configured to check these values during execution.

    Any kind of help/suggestion is greatly appreciated.

    Concerning
    Deepa

    To do this, you change the task of bpel and specify the condition to jump for the task. In the rule to jump, you must specify if the applicant is responsible for the user (the two values that you get in the payload). Set it up this way auto approve request to the Manager.
    Also be sure to affect the outcome of the BPEL task of condition of approval so that IOM does not wait for the State.

  • Fire power Cisco not be able to block torrent traffic

    Hello, I'm testing a Cisco ASA 5515 x with firepower (IPS, AMP, licenses of URL filtering). I created and implemented an access control strategy. The traffic of the L3 - L4 moment in our Organization is blocked by Firewall ASA. With SFR module I want to block Skype, Teamviewer, Torrent and intrusions from the Internet.

    My IPS policy is applied to the rule of Inspection of the threat which is the last rule in the policy of the CA. What I understand all traffic will be allowed, if it will be accepted by the IPS policies and AMP. The problem is that if I disable rule number 8 (Torrent of deny), then I can download torrent files and I am able to download torrent using Utorrent application content, but I think that this traffic should be removed by IPS policy. If I activate the rule number 8, download the torrent file is prohibited but not all torrent traffic fell (continue some of my torrents in Utorrent to download). I thought that IPS policy that is attached to the rule of Inspection of the threat will block all traffic that matches the IPS policy because the traffic of the intrusion. When I check the events I see that result Inline for the torrent traffic "fell". Why am I able to download torrents in Utorrent?

    Hello team,

    IPS and policy file will take part in the inspection. In your case, we look at detailed AC and political intrusion policies configured. Could you please open a TAC request to look at even.

  • Filtering on ASA - CX without content license

    Hello

    Please can someone advise if it is possible to configure the URL/content filtering on a box of ASA - CX with an expired license?

    I connected the PRSM onbox, I can't create objects and policies needed to enable filtering.

    Also, I redirect to installation to the CX (for testing purposes), however in the current state (without a license) browsing all watch a 'redirect' screen and nothing happens the message stay here and does not have traffic redirected to the ASA. It is also due to licensing (there is currently no policy in place)

    We are in the process of buying licenses STROKE and WSE, so I just want to check what the expected behaviours should be.

    Thank you very much

    CX is end of sales and new licenses are not sold by Cisco as of August 17, 2015. Reference.

    A CX unlicensed generally cannot apply, create, or modify policies through its premises PRSM (or he can take an out of area PRSM) if the license for the feature is not present and active (IE out of date). It is further explained in the section User Guide on licensing.

  • Cisco utilities - RHEL6

    Hello

    We are looking for install OS RHEL6 on our servers UCS B200M3. Does anyone have information on Cisco has everything similar RHEL6 utility for the following HP utilities:

    • hpacucli - utility CLI to configure the operating system RAID array
    • hpasmcli - display/game/change settings in the BIOS such as hyperthreading, control startup - to show the condition of the equipment, such as fans, power supplies, etc. - shows, repair and erase the IML - the ILO journal
    • hpbootcfg - to define which device to boot from the next time the system starts.
    • hponcfg - configure ILO/RILOE II from the operating system without requiring a restart of the server

    Thank you very much, Paul

    Hi Paul,.

    For local disk to a server RAID configurations, we have the Manager of the UCS.

    For viewing/creating/changing the BIOS settings, we have the Manager of the UCS.

    To configure how a server gets started, we have the Manager of the UCS.

    For the configuration of the OOB access, we have the Manager of the UCS.

    All the utilities you mention require some additional programs/agents/etc should be loaded or included in the host operating system.  With UCS Manager, we require * zero * programmes/agents.    All the magic we do runs under the operating system - in the UCS Manager.

    What happens when you use all the utilities above in a server HP environent?    Well, if ever the server fails, you need to manually reapply all the configurations you made, because these parameters are not really part of the 'server' that interest you.  Whereas, in an environment of UCS, if ever the server fails, then all you have to do is re - associate service profile with a different blade/rackmount.   Because in UCS, we don't "set up servers with settings" - we create servers with policies.   And these policies are used to define the 'server' - that you care - not just the hardware.

    There are 2 main focal points: Service availability and minimizing the number of Management Points.   We are confident that we have a solution that is more attractive than HP in this regard.   And make our customer base 30 000 + (time expansion).

    So to answer your question more directly-"Cisco UCS has a commercial dozen different server configuration to configure servers in a piecemeal way?"      -No, we don't, and that's the point.

    I hope this helps.   Thanks for your question.    See you soon,.

  • Configure downloadable ACLs

    Hi all

    I have configure 802. 1 x with ACL downloadable on IOS version 12.2 (52) SE and 12.2 (55) SE4, I found that there is a different behavior.

    On 12.2 (52), I need to create a default ACL and apply to the ACL on the interface.

    On 12.2 (55) SE4, there is no need to create an ACL does not apply on the default interface.

    I check the configuration guide, seems that the default ACLs must configure on the interface.

    http://www.Cisco.com/en/us/partner/docs/switches/LAN/catalyst3750e_3560e/software/release/12.2_55_se/configuration/guide/sw8021x.html#wp1316124

    Anyone knows an improvement on Cisco IOS?

    Kind regards

    Alan

    Yes, the behavior has changed. From 12.2 (55), you do not have to configure a default static ACL.  Here is a URL reference. It is documented in the same URL you posted.

    Starting with SE Cisco IOS version 12.2 (55), if you do not configure a static ACL on a port, a dynamic Auth-by default-ACL is created and its policies are applied before DACL is downloaded and applied.

  • Permission, restrict commands

    Hello everyone, I have a problem, I use ACS 5.3 I have a set of two DeviceGroups (router & switch) and two set of users (G1, G2), here is my question, how can I do this:

    G1: complete hace can access DeviceGroup1 and DeviceGrup2--> it works

    Here's the tricky part for me...

    G2: can 'read only' access to DeviceGroup1, but full access to DeviceGroup2

    Anyone has asked this before, or is there any documents on how to do this.

    Thank you very much!!

    Hello Cesar-

    You can certainly do GBA. When you create your authorization policies, you can be very flexible with how you grant and deny access to your devices. For your example, you can create rules that are based on:

    1. the group identity of the end user (which may be both internal and external or AD)

    2 type devices (switches, routers, etc.)

    3. the location of the device (A Campus, Campus B, etc.)

    Thus, for example, if the user is in the Group of network admin, then he or she will have full access without worrying about the location/type of device (1 screenshot) but if the user is Let's say a "switch admin", then that user will have full access to toggle (2nd screenshot), but only read only access routers (screenshot 3)

    I hope that makes sense!

    Thanks for the note!

  • A single local user can belong to the Group 2-policy?

    I have a Cisco ASA 5505 that I install with a SSL VPN. It's for personal use, and I so didn't need anything other than local authentication.

    I created two group policies:

    internal TunnelLAN group strategy

    attributes of Group Policy TunnelLAN

    VPN-tunnel-Protocol svc webvpn

    value of server DNS 208.67.222.222

    As you can see, I would like to have a profile/policy where I only encrypt data will tunnel of splitting my ACL, and I would like to have a profile/policy where I encrypt all traffic.

    The question ive been fighting is - it does not seem possible to associate more than one group by user policy. If anyone can confirm this? If it IS possible - can you tell me how I associate the two groups to my local account?

    Thanks in advance.

    Edit: I'm running ASA 9.1 (1), 7.1 ASDM. I'd be happy to share several config if requested.

    Hi Brandon,.

    You can always set a group policy on a tunnel-group (connection profile). So in your case, you can create two tunnel and specify each lives in group in respect of each type of tunnel-group so.

    !

    type tunnel-group TunnelLAN-vpn remote access

    tunnel-group TunnelLAN-vpn-global attributes

    Group Policy - by default-TunnelLAN

    !

    !

    type tunnel-group TunnelAll-vpn remote access

    tunnel-group TunnelAll-vpn-global attributes

    Group Policy - by default-TunnelAll

    !

    When you connect, you can decide which group policy you want to apply through the selection of the desired tunnel-group.

    As long as you do not restrict the local user for a specific group (under the user attributes) policy all users can connect to one of the Tunnel-group defined in the ASA so long as they provide key correct pre-dhared

    Please note the useful messages.

  • ASA and group URL

    So I have the need to provide two SSL VPN environments for two different clients on the same ASA 5510 appliance.  Can I create two group policies, each with a group unique url and then assign a certificate corresponding to the Group url?  From the point of view of the intellectual property, they would all be hitting the same outside IP address.

    Ex:

    Group_policy: customer

    Group URL: https://remote.customera.com

    SSL certificate: remote.customera.com

    Group_policy: CustomerB

    Group URL: https://remote.customerb.com

    SSL certificate: remote.customerb.com

    Thank you!

    -Craig

    Hey Craig,.

    On your request, let me divide 2 parts:

    1. can you use 2 different urls on the SAA for two separate connection profiles

    2. can you use 2 separate certificates to validate the two URLS

    Regarding your first question, yes it is possible. You will need to create 2 separate group policy and 2 connection profiles Tunnel aka groups. Under each tunnel group define a separate url group and assign the corresponding group policy. Your configuration might look like this:

    In-house strategy group customer ASA (config) #.
    Strategy of customer attributes group ASA (config) #.

    .

    .

    .

    (to configure the respective attribute)

    ASA (config) # Tunnel - group customer type remote access
    ASA (config) # Tunnel - group customer General attributes
    ASA(config-tunnel-General) # by default-group-policy customer

    ASA (config) # tunnel - group customer webvpn-attributes

    ASA(config-tunnel-WebVPN) # group - url https://ASA1/remote.customera.com

    Repeat the steps above and replace "customer" by "CustomerB".

    As for your second question, you can only configure a trustpoint to be used with a single interface. If you do one of the following:

    1. get a UCC (Unified Client certificate) to your ASA:

    Get a UCC with multiple CNs / without (Subject Alternative Name extensions) for each domain COMPLETE/IP ASA. If you need a certificate of the UCC with CN to FQDN or IP and no master for each SAA: ASA-1 FQDN or IP, ASA-2 FULL FQDN or IP domain name and so on. Several suppliers PKI/certificates are supported entrust.com, verisign, UCC:godaddy.com, etc.

    Note: the ASA cannot generate a certificate request (CSR) signature with multiple WITHOUT (CSCso70867 is development requesting this capability), so you must be the seller of the PKI to submit the entry for you.

    ASA set a trustpoint "and Install/import the UCC certifcate in this trustpoint. Bind this trustpoint to the external interface.

    2 OR a certificate with wildcards. Generic certificates are discouraged in favour of the UUC certs. According to a seller, Entrust, these are the 2 main reasons:

    1. UCC is more secure than Wildcard certificates since Entrust UC Certificates specify exactly the hosts and domains must be protected
    2. UCC is more flexible than Wildcard certificates since Entrust UC certificates are not limited to a single domain

    I hope this helps.

    Kind regards

  • OBIEE permissions

    Hello

    I have problems to set permissions in the catalog of OBIEE (Oracle Business Intelligence, 11.1.1.6.4)

    Current situation:
    An LDAP external (ADAM) has already been set for the authentication of users and all works well (this means LDAP users access BI). By default, all authenticated users get "consumer Bi-role.

    How it should be:
    I have set permissions for 10 users - > 3 with Admin role, 3 read/write and read-only 4.

    What I did:
    -By Oracle Enterprice Manager:
    1. I created (option "create as") three new 'roles of Application' (Member "My role as an administrator"-> "My author role" Member-"My role of consumer");
    2. I added the mentioned users above to each of my "Application roles.
    3. I created (option "create as") "enforcement policies" for each of my "Application roles.
    4. I rebooted all the Bi components (Server BI... Presentation...) ;
    -In the catalogue:
    1 connected with the default administrator user, called weblogic.
    2. I set users access to reports, dashboard as a following pages:
    * "My role as an administrator"-> "total control".
    * "My author role'-> change
    * "My role of consumer"-> read
    3 disconnected.
    4. connected with one of the users addes to an application ('my role administrator') role created in steps above.

    At this point, I guess to have "Full control" permissions But once I logged I can't help: create new analysis, see dashboards and so on.
    I try to check in 'My account' in the tab "Groups and Application roles" and I couldn't see "My role as an administrator", but only the default 'consumer Bi-role.

    Is there someone who could give me some suggestions?

    Thank you very much
    Sam.

    Sam HY,

    Try to create an application without space role in the name such as MyAdminRole.

    A presentation services application role permissions are given only in the privileges tab.

    Then:
    -you created a simple application role,
    -Add a group to a user to that application role
    -connection in BI Presentation Services (Dashboard)
    -Check that the user has been the role of enforcement (as you did) in my account.
