IPS design review

Hello ,
Could you review my IPS design (the topology picture is in the attachment) ? Can I have one IPS with three or four ports attached to the same switch in an etherchannel? I am talking about one IPS with multiple interfaces. For example two IPS with four interfaces in the switch's etherchannel group with eigth ports. ( IPS's interfaces are in VLAN pair mode )
Kind Regards.

Sorry, i have forgotten to attach the topology picture.

    Is there a brief Checklist that mentions All the Best Practices; To get me started.
    Thank You !

    Hi,
    Usually companies like IBM, VMware, HP, etc. have their own Reference Architectures.
    A lot of Reference Architectures are  posted publically by VMware. Try to search, if you can find the one which suits your needs.
    If you work in one of the BIG companies, try to check your internal documentations.
    Good Luck

  • IPS Design Help

    Hi All,
    There are two ASA with failover and two switches, one internal switch and one DMZ switch. Both ASAs connected to two switches. Now we want to implement IPS here. we are using 4240 model. I want to use two inline interface pairs one for DMZ and one for internal. But the problem is there two ASA. If you show me high level design and how connect ASA to IPS then to switch, that would be very appreciated.
    Thanks
    Al

    THanks for your reply,
    ASA has three interfaces, one is outside, one is inside and the other one is DMZ. inside and DMZ interfaces are trunk ports with bunch of VLANs each and they are connected to two switches with trunk ports. these two switches are not connected to each other and they are connected to seperate network.
    sorry for incomplete description. any suggestion would be very apprecited.
    thanks

  • HA IPS Design

    Hi,
    I'm designing a security system that involves:
    2 x inside firewalls (ASA5520)
    2 x switches connected together (for failover)
    2 x IPS (4240IPS)
    2 x switches connected together (for failover)
    2 x outside firewalls (Juniper SSG)
    I'm at looking at active/standby or active/active for the firewalls but am not sure if the IPS supports the same with stateful failover? My concern is with asymmetric routing if both IPS's are active and independant. Can I guarantee that a session will use the same IPS for inbound/outbound flows and not get separated across two IPS's?
    Any guidance is appreciated.
    Thanks, Wayne

    IPSec Stateful Failover (VPN High Availability) is a feature that enables a router to continue processing and forwarding packets after a planned or unplanned outage. You can employ a backup (standby) router that automatically takes over the primary (active) router's tasks in the event of an active router failure. The process is transparent to users and to remote IPSec peers. The time that it takes for the standby router to take over depends on HSRP timers.
    IPSec Stateful Failover (VPN High Availability) is designed to work in conjunction with Reverse Route Injection (RRI) and Hot Standby Router Protocol (HSRP) with IPSec. When used together, RRI and HSRP provide a more reliable network design for VPNs and reduce configuration complexity on remote peers.
    RRI and HSRP are supported together with the restriction that the HSRP configuration on the outside interface uses equal priorities on both routers. As an option, when not using RRI, you can use an HSRP configuration on the LAN side of the network (equal HSRP priority restriction still applies).

  • IDP IPS Design

    Where is the best place to put IDS/IPS device? For example, outside/inside of the Firewall?
    Does Cisco has any recommendation?
    Does anybody has good design to share with?
    Thanks,

    There's probably not a "1 size fits all" answer here. If you have unlimited $$$ then you could sprinkle sensors all over you network but I'm guessing that's not the case.
    As such your going to need to take a few steps that will help you design your IDS/P deployment.
    First you'll need to map out your network and then decide what assets are the most critical. one place where most people will deploy some IDS/P is in a DMZ. This is an obvious choice as the assets there are accessed by untrusted sources.
    Another good spot is behind the firewall. Assuming that the sensor can handle the bandwidth this will let you see traffic coming in from the DMZ(s) and going out from the trusted networks. You'll be able to see things like traffic from PCs infected with Zombies and the like on this sensor.
    Next if you have your "critical" assets (say like DB servers and the like) segmented off on their own internal network then putting a sensor where it can see traffic going to/from them makes good sense too. This will again give you a good look into what if any attacks are being directed at them. If it's a server in the DMZ you'll already pick that up on the DNZ sensor but the one near you critical assets will also show any infected PCs or hosts on the inside trying to hit them.
    I don't normally put a sensor on the "outside" as there's not much value in that. There's way too much data there to handle and if 90% of the traffic is being dropped by your firewall rules why bother worrying about that anyway? Putting sensors in the firewall like the AIP-SSMs or putting external sensors where they can see the other firewall interfaces will show you the same traffic minus all the junk that gets dropped by not matching a rule.
    Hope this helps. I know it's very general but you really need a detailed map of your network topology and traffic flows to make the best choices where sensors should be.

  • Network Design Review - Best Practices

    Looking to start a discussion around best practices for inbound network design at the core. 
    The planned devices are as followings:
    Edge Routing / DMVPN - Cisco 2951
    Cisco UCM / IP Phone VPN Concentrator - Cisco ASA 5512-X
    Cisco AnyConnect SSL Client Concentrator - Cisco ASA 5515-X
    Cisco FirePower / IPS Device - Cisco ASA 5515-X
    The plan is as follows:
    All traffic enters through the 2951. 
    DMVPN traffic will go directly to the FirePower Device and then to the core network.
    IP Phones will pass-through 2951, enter 5512-X for VPN, go to FirePower and then to the core network.
    AnyConnect Clients will pass-through 2951, enter 5515-X for VPN, go to FirePower and then to the core network. 
    Wondering if anyone else has completed a similar setup and any issues you may have fun into. 
    Basic diagram attached. 
    Thanks!

    There really isn't a true two factor authentication you can just do with radius unless its ISE and your doing EAP Chaining.  One way that is a workaround and works with ACS or ISE is to use "Was machine authenticated".  This again only works for Domain Computers.  How Microsoft works:) is you have a setting for user or computer... this does not mean user AND computer.  So when a windows machine boots up, it will sen its system name first and then the user credentials.  System name or machine authentication only happens once and that is during the boot up.  User happens every time there is a full authentication that has to happen.
    Check out these threads and it explains it pretty well.

  • IPS design

    I have 2 unit ASA 5520 with AIP-SSM-20 for front-end and 2 units ASA5520 with AIP_SSM-20 for back-end.I also have 2 units catalyst 6509. How should my design looks like.

    It all depends on what you are trying to accomplish and what features you are using in each ASA. The outside ASA, as a firewall can host serveral inside networks (limited by the number of interfaces in the ASA) each netowrk can have a different firewall policy assigned. If that meets your firewall needs, then you might not require a second set of ASAs.
    You have not provided enough network requirements detail to even make an guess of what you need.

  • IPS design question

    Hi All,
    I have two ASA as active/standby failover. these two are connected to 3750 switch through trunk port that carry vlan 10,20 and 30. I want to deploy IPS in between with inline mode. I am little confuse how to connect IPS here. should it be connected with both two ports to switch, or it should be connected to ASA from one end and then connected to switch with another end.
    If you show me how to connect IPS here, that would be very appreciated.
    thanks
    Alex

    With inline vlan pair only one IPS interface is utilized (it has to be a trunk), have a look at:

  • Technical Design Review Question: mySAP Execution Architecture.

    I got my hands on technical design documentation for a project on COPA budget. I came up with a few questions but I will post them separately for fast closing and awards:
    1. In the Requirements discussion, I came across something
    “Job naming conventions apply… and completion of Autosys Job Schedule request form is required….Forward this form to the mySAP Execution Architecture team for processing”
    Is this a an internal team or it refers to some group at SAP company?
    Is the Autosys Job Schedule request form a standard for or you think the environment had just come up a form for their internal processes? What may this include?
    Thanks.

    Hi,
    If I understood correctly, The organization wants to maintain a document on jobs to be maintained regularly in production system. It will be used as a  reference in the support of BW production activities.
    I hope, the mySAP Execution Architecture team for processing is the internal team from your client.

  • Multiple WAN site redundancy design review (dark fiber, p2p, DMVPN)

    I'm re-designing a couple of wan sites.  I'm using EIGRP over both some leased dark fiber and p2p provider connections.  The attached (pdf) physical topology says it all, I'm thinking of using ip sla to track and inject routes over prefered connections, but really just looking for feed back if someone is interested in taking a look. 
    I've bought 2 2951's with es3g-16-p modules so I can build svi's and do hsrp between the paths, building redundancy between the 3 available paths back to our enterprise core (1Gbps, 40Mbps, 50Mbps).
    multiple vlans at both sites...
    e.g.: (wan site1 (vlan 10-15), want site2 (vlan 16-20))
    Thoughts and thanks?

    hi there
    not sure why you need to use DMVPN if it all internal same internal network unless you need to have all the traffic between sites to be encrypted
    anyway in general i would say of use the direct link to reach the directly connected networks per site
    example using site one 100M link to reach DC and WAN
    and use site2 50M local link to reach WAN as primary path and use the site1-site2 fibre to reach DC as primary path for site2 this could archive a good load sharing and reduce the load on the link between site1 and site2
    IP SLA in a topology like your for sure can very helpful to improve failover time and make the routing more topology aware
    hope this helps

  • DMZ layer design review

    Hello,
    I would appreciate if some can share their experience/problems with below design between Core-Firewall-DMZ-Aggregation setup.
    1. There is a Layer-3 connectivity between core and firewall segments with L3 point-to-point links running OSPF. The active firewall(FW-A) forms ospf neighborship with Core-A and similarly FW-B forms ospf neighborship with Core-B and Core-A / Core-B form ospf neighborship.
    2. Aggregation switch and Firewall are connected over L2 trunks and OSPF is running over SVIs (VLAN 13 / bcast segment), Aggregation switch-A is elected as DR and Aggregation switch-B is BDR, both firewalls have configured ospf priority to zero. FW-A(active) forms ospf adjacency with Aggregation-A and Aggregation-B, and each Aggregation switch forms ospf neighborship with the active firewall only.
    Is there any chance that the broadcast network b/w Aggregation switch and Firewall can cause any problem when any of the aggregation switch reloads.
    I have attached a rough sketch for better understanding.
    Regards,
    Akhtar

    It's cute but Flash for navigation is pure poison because many browsers don't support it.  Most notably Apple iPad, iPhone & iTouch do not support Flash.  How will those users navigate your site?
    For all practical purposes, Flash is dead as a web technology except for gaming sites and special device apps.
    I think a better choice is CSS styled menus to support the majority of users.  If you want to add some animation  to your site, look at HTML5, CSS3 transitions and JavaScript

  • Technical Design Review Question: Key Figures

    I got my hands on technical design documentation for a project on COPA budget. I came up with a few questions but I will post them separately for fast closing and awards:
    In the discussions of Key Figures, a table was provided showing Name, description, source field, data type and Unit. With the exception of 5 of them, all the key figures had data type as Curr(17,2).
    My confusion is why all their equivalent Units were 0Currency while the 4 exceptions which had Data Type QUAN(17,2) had Units  of the form zvv90_ME, zvv094_ME, etc.
    I will appreciate your thoughts on these.
    Thanks

    All the Key figures which are curr(17,2) are meant to be used as Amounts which can be ties to different currencies..
    Like The key figure might have a number 1,000 and the corresponding entry in 0currency might be USD which means its $1000.
    You can find all the valid currency keys in the TCURC table..
    On similar lines For Key figures which specify quantity a few examples will be ;
    100 pc
    30 Hr
    Where the unit is stored in 0UNIT.
