Placement of IDS and IPS, inside or outside?

Hello

I have an IDS and IPS, now decide where they should be placed. ID inside and outside of the firewall IPS, or vice versa. Ive read various advantages and disadvantages, but I would like to get some advice from people who have experience in investment.

Thank you

The SAA is a firewall that has the IDS/IPS functionality, in addition to other things - where a "security device".

As a firewall, the device of the SAA is placed on the edge of the network, i.e., probably as the first device inside the WAN (bridge, modem) connection, although sometimes it makes sense to have a router on the outside, especially if there are multiple connections to ISPS for redundancy, load balancing, or quality of Service implementations.

What ASA model are we talking about?

IDS/IPS functionality produced inside the unit - there is a "module" that is internal to the unit that manages the functions. In the case of the IPS, it will prevent the malicious traffic to enter your organization (often called inside network) network. In the case of the IDS, it will report all traffic and issue a warning by all means have been configured. These correspond vaguely to inline mode and "Promiscuous" mode respectively.

I'm no expert, but I hope I could help answer your original question...

    (I wondered if ASA has also a cost - efficient as PIX failover solution-discounted price for the unit of failover).

    If I choose the ASA VPN edition is it possible to add IPS inside module?

    Hello

    Q: what does AP means here - what software? In this case you have to buy a second unit (at the same price) for the recovery of?

    The "ASA5540-AIP20-K9" is only for 1 unit of ASA, with function of software HA (active/active, active / standby). You can add/buy another unit to achieve HA/recundancy.

    I think that the price of a unit all them is always the same, ASA has no unit to voluntarily make the function FO.

  • I had problems with my gc, cleaned and he is now allowed outside my control file system system, that it will take place at 68% and stops running

    I had problems with my graphics card cleaned and it works well apart from the system of checking file system on C: turns 68% and stops. If I have to cancel the computer checking seems to work ok, or is it?

    I guess that Mark_S_Sloan is talking about chkdsk /r or running a disk check with fixed error on a restart. so I would say that what I used to say the performance is chkdsk:

    The chkdsk/r can take a long time to complete depending on the size of the volume, the amount of data on the volume, the speed of the system and what chkdsk is to do.  It take about 2 hours for chkdsk/r run on one of the volumes of my1TB (I'm a right that I rarely run).

    It may take a long time for chkdsk complete or they seem to be "stuck".  Be patient.  If the HARD drive led blinks always, chkdsk is something.  Keep an eye on the amount of the percentage to be sure that it is still making progress.  It may even seem to go back sometime.  Give him a chance.

    @Imran M - Microsoft technical support engineer:

    Don't you know that the performance of the auditor of the filesystem (sfc/scannow) does not provide a percentage of completion?  Have you ever used it?

    He also really tell you anything about what he did, or could have done when it is executed even if she finds something to do.

    Everything you see in the Event Viewer system log are messages like this:

    Event type: Information
    Event source: Windows File Protection
    Event category: no
    Event ID: 64016
    Analysis of file File Protection Windows has been started.

    .. few time later...

    Event type: Information
    Event source: Windows File Protection
    Event category: no
    Event ID: 64017
    Windows File Protection file analysis completed successfully.

    Even if sfc/scannow find something to do, you will know about it, because it is not connected.

    That's why use sfc/scannow still more of a waste of time.

  • PartialTrigger of different region and targets inside the iterator.

    Hello

    I use 11.1.1.6. Basically, I've got A Taskflow is a region that has inside an iterator that creates several commandLinks. I need to refresh a component of the parent page (one is the region) so I will try to accomplish the task using partialTriggers on components of commandLinks.

    My region ID is = r1, so I put the partialTrigger = "r1:iter1:cl1", but does not work. If I put a commandButton control in my taskflow region but outside of the iterator and defining the partialTriggers = "r1:cb1" then it works.

    An idea to solve this, or a different approach?

    Never mind. This works if partialTrigger = "r1:iter1:cl1" is used. It was that I was wrong using IDs.

    Hello world

    What you describe is quite complex, but here are a few tips.  The key is to establish a correlation between the coordinate system of the robot to the coordinate system of the camera.  I guess that the camera is statically located above the pick-up area?  I move the robot at each corner of the frame to its choice position vertically and note the position of the robot at these locations.  These 4 points in space will be correlated to X, coordinates of pixels in the camera image.  Basically, you need to write a sub - VI with entries being pixel X and is coordinated and coordinates output being the robot.

    Writing a test application saying the robot to get pixel location to any X, Y in the framework to test your Subvi.  If this does not work, then you need to set up a correspondence to the model.  You probably want to do a geometric pattern match.  Take a look at this example: http://zone.ni.com/devzone/cda/epd/p/id/5555

    You will need your pattern match algorithm to return both the coordinates for your robot, and the orientation of the tool needed for good pick up the object (if the pick-and-place robot tool requires to be in a specific direction).  If it's basically up to you will convert the object X, Y and rotation angle in the framework that you receive correspondence from model to any coordinate system, the robot uses.

    The placement algorithm could be simply an adjustment of orientation to the object being investment and then investment positions could be an array of coordinates of robot which you browse after each pick.

    Be sure to implement security mechanisms in your algorithms so that the robot can never go somewhere outside of a safe range of coordinates.

  • Techniques need more details 4250XL IPS and IPS-4255

    4250XL IDS launched before the IPS technology, am I right?

    Can I deploy a 4250XL ID as an IPS, if yes, then it's true to upgrade this version IDS 4.1 to IPS ver 5.0

    I add 4 10/100/1000BaseT ports on ID 4250XL.

    Because, I have to deploy IPS to 1 Gbps throughput.

    and I could not find an IPS in CISCO will produce 1 Gbit/s with 4-port 10/100/1000BaseT.

    How many simultaneous sessions support IPS 4200 series.

    How can I use feature Redundant Power Supply on IPS-4255.

    Technical documentation 42xx is linked off the coast of http://www.cisco.com/go/ips. I don't know if IPS 5.0 information is still (it's kinda new). There is no option RPS for the 4240/4255, but recommends the use of a UPS would be justified for packaging line if you have unreliable power.

    There is no provision for failover in the transducer (other than the bypass mode), but there are drawings (I hope bound off the page that I mentioned above) to do network active / standby designs.

    The 4240 and 4255 do not have redundant storage... they have no HDD due to reliability problems. They run a flash and ram disk configuration.

  • Redirection of port from inside to outside. Also of ICMP on the inside.

    I'm working on a FWSM using code 2.2 (1) and I would like to proxies all web requests to a box of squid of the interface from the inside to the outside and I am using the static command. All the examples I've seen pass from outside to inside. I tried the following and it doesn't work.

    Internal network interface: LabA

    Box of squid on the external network to IP: 1.1.1.1 answer on port 8080.

    Command:

    static (LabA, outside) interface 8080 tcp 1.1.1.1 80 netmask 255.255.255.255 0 0

    The question I have, is the static command above works of highest to lowest? If not, is there a better way to solve this problem other than to put a map of the route on the interface routed to the MSFC?

    Second problem, I can't ping my inside interfaces from the outside? I can ping interfaces of security inside/down level of the Interior. Is this a problem where you can leave the same interface that happened you? I encouraged icmp in access lists.

    Thanks for the help.

    Static defines a permanent translation betwwen two interfaces and is used for traffic between these two interfaces in EITHER DIRECTION. The problem you are experiencing probably is the static ports (8080 and 80) are the port of destination. According to which direction your traffic flowing port 8080 or 80 can be the source port, and in this case this static has no effect.

    Regarding your question ICMP, you cannot ping a PIX/FWSM to another interface interface. This was always the way it works, and there is no way around it. To test connectivity between the interfaces you have to ping a host interface to another host out of another interface.

    Hello

    I don't think you have dynamic PAT configured for traffic from the VPN Client user who is supposed to browse the Internet through the connection WAN ASAs.

    Try adding

    NAT (outside) 1 10.47.60.0 255.255.255.0

    Also, the "packet-tracer" you question is not simulate the connection from the VPN Client. The user of the VPN Client is not behind the 'inside' interface and the Clients VPN address space does not include the IP 10.47.70.20.

    When the Client VPN connection is active, you can use the command "packet - trace"

    entry Packet-trace out tcp 10.47.60.x 12345 8.8.8.8 80

    While of course, replace 'x' with the real IP that the user got to the ASA

    Hello

    I tried an example with Flex3 ProgressBar. I write the scenario in which it was OK in one case and bad in another case.

    Please tell me what's not here in the case of wrong:

    The program is linked to:
    I have the button when click on that I load the Image. There is no button and its event listener mentioned here.

    Correct approach:

    This works also very well the Image and ProgressBar are in the same container called HBox

    < mx:HBox >

    < mx:Image id = autoload "image" = "false" / >

    < mx:ProgressBar id = "MYPB" source = "{image}" / >

    < / mx:HBox >


    Wrong approach:

    Below does not work as I placed the ProgressBar outside the container called as HBox

    < mx:HBox >

    < mx:Image id = autoload "image" = "false" / >

    < / mx:HBox >

    < mx:ProgressBar id = "MYPB" source = "{image}" / >

    Please share your ideas like why it behaves in this way.

    Hi Kiran.

    I don't think that either the approach is wrong, it no way performed by placing the ProgressBar inside a container or outside the container.

    Run the sample application below. It loads to the two approaches.

  • Gradient fills that radiate to the inside or outside

    I would like to be able to create a gradient between the paths are creating buy using the command "path offset."  I want the filling to go either from the outside path inward or vice versa.  Is this possible?  I'm very very very very new to illustrator and I've been Googling for hours but I don't think I know the exact terminology to search for.  I have attached an image using a circle that demonstrates the effect I'm after.  But I would like to apply to paths in weird shape... but always have a smooth gradient of the path from the outside to the inside.

    DB,

    I would like to be able to create a gradient between the paths are creating buy using the command "path offset."

    In fact, you describe the first step in the creation of the mixture for the paths of contour. Simply select both paths and:

    (2) object > blending Options, choose align to the path, especially if you can rotate / whatever later and choose colors or the steps specified; with a number suitable, the latter will normally result in a smaller file, and it is necessary if one or two objects has a gradient;

    (3) object > blend > make.
