Syn flood signature 6009/0 actions

Hi is there an option when this signature fires to block the attacker or this attack and not just log the attack? I tried to set the actions but the log says no action taken.

Hi Thx for the answer. I did add the action but no luck or does it nog log this action? The traffic hits the client inside the network so the ips does not block.

  • Syn flood DOS (6009)

    The signature for syn flood DOS (6009) has two values that I can see will alter the signature threshold.
    event-counter
    event-count: 2600 default: 200
    event-count-key: AxBx <defaulted>
    specify-alert-interval
    yes
    alert-interval: 2 default: 2
    The definition for the signature is that it will detect a flood of TCP SYN packets at a rate of 100 per second or greater. We have tried to adjust the signature that this value is higher and no matter what the event count is, it continues to trigger in our environment. At 1300 syns per/sec, (event-count: 2600) an alert is still received for http proxy servers.
    Have I over looked the parameter that needs to be adjusted in order to increase the threshold of this signature or is it just not tunable.

    By default, flows with 200pkts/2sec above are alerted. You can change the threshold by CLI

    I cannot get at the meaning - address 0.0.0.0?
    It`s bug?

    No, it's not a bug. The scanning signatures summerize the attacked addresses into 0.0.0.0
    This is because in scans there are a LOT of dezstination addresses that are hit inorder to fire the signature but there is only one attacked address field in ever signature.

    Hi,
    I configured IDSM/Blocking feature for preventing DoS attack. I used ICMP flood and UDP Host Flood signature. These signature actions have been set to produce alert and request block host. I use packit tool for test. ICMP signature detects icmp flooding and blocking is done successfully but UDP Host Flood signature does not detect udp flooding. I repeat test scenario with different values for “Rate” but none of them detect flooding.
    Is there  specific setting for UDP Host Flood signature or for Net Flood UDP.
    Thanks,
    Hedye

  • SYN flood attack log In CSA MC

    I got an SYN flood attack log in CSA MC
    CSA log: TESTMODE: A potential SYN Flood attack has been detected. This may also indicate a possible routing problem. Reason: The TCP Listen Queue is full using interface Wired\HP NC7781 Gigabit Server Adapter #2. TCP: CSA MC IP/5401->local Instance IP/4418, flags 0x12. The operation would have been denied.
    (Note: In log I have specified CSA MC IP and local Instance IP instead of its IP address)
    I understood that SYN flooding is a type of denial of service attack and this alert has occured when a TCP/IP connection was requested by MC to the Instance. It has resulted in a half open connection, as the return address that is not in use. MC has detected it and it got denied.
    Please let me know what action I have to take at tins point?
    Thanks

    Arumugam,
    We've been having similar issue regarding SYN flood alerts. The affected system in turn starts to send additional ACK requests. This results in issues with the IIS functionality on that server. Clients begin to no longer have the ability to access the site hosted on the server. We've been battling between Cisco and Microsoft on this one. The issue appears to have started around Patch Tuesday in February.
    My question to you is this: Have you noticed any latency with the system that is reporting the SYN flood? I'm curious if the problem is local to us, or possibly wide spread.

  • A SYN flood attack!

    when i run
    server$ dmesg command i got this message.
    WARNING: High TCP connect timeout rate! System (port 8080) may be under a SYN flood attack!

    is the ip given a public ip and is the sun machine behind a firewall or running a firewall? most new deployed servers will not see enough traffic on segments behind firewalls to cause messages like this. ive run scanners that can cause messages like this or test clients that generate load as well...

  • Syn flood attack?

    Hello,
    I work in an organization in which there is an automatic monitoring of network connections. Yesterday I had a notification of a possible syn flood attack originated by my Mac targeting an IP address (and port: 8000) that I found out to be associated to an internet radio. I did some network monitoring and I found out that with iTunes closed there were no packets with that IP as destination address... has anyone experinced such a problem?
    Sincerely
    Giuseppe

  • Syn Flood :0(

    We have a very large network at work and we have been having some internet timeout issues so we got some people in to monitor packets and perform a general network health check.
    I got called up by the networking people saying that there has been a syn flood detected coming from my mac address on my macbook :0(
    I know that mac’s are subject to network attacks but I thought that I have covered all my bases, I have Symantec installed and I keep up to date with my security updates etc.
    Can anybody give me any pointers as to where to start to diagnose if there is an issue with my mac, I have used macscan and that found nothing I have also used little snitch to see if anything crops up asking for a network connect but nothing :0(
    Any suggestions are greatly appreciated!

    Sounds like something that should be posted to the Networking or Server Products forum.

  • Syn flood software?

    i'm trying to test some syn flood mitigation techniques in my lab studies and i'm looking for a decent syn flood prog if anyone knows of one. tia.

    If you check out the Sectools website (sectools.org) or if you download BackTrack (http://www.remote-exploit.org/backtrack_download.html) you can find a lot of really useful tools. Most of these are hacking tools so be sure to use them in accordance with whatever policies you are subject. I've used hPing in the past to simiulate syn floods and dDos attacks.
    Good luck!

  • Ips signature 6009/0 tuning

    Is it possible to tune this signature and to set it to 200 syn requests a second instead of 100 per second? How do I do that?

    Hello,
    As per the benign trigger details for 4003-0:
    "Many network management tools, such as HPs Open View, provide network mapping capabilities. This may include a mapping of available network services, so UDP port sweeps may be expected from these systems.
    DNS (Port 53), LDAP (Port 389), and Active Direcory (Port 88) servers have been shown to cause false positive alarms when responding to numerous queries from the same host.
    Due to the stateless nature of UDP traffic, this signature may fire on any application that makes multiple queries to the same UDP service on another system. Because the application often uses a different source port for each request, the responses from the service may be mistaken for a port scan by the sensor. If when examining the alarms for this signature it is determined that a known network service is the source port for this alarm, a filter can be used to eliminate the false postive alarms."
    Additionally, from the Suggested Filters section:
    "Exclude network management stations as sources and destinations. Exclude DNS / LDAP / Active Directory servers as sources."
    If the signature has only recently started firing for that DNS server, then you might want to read http://isc.sans.org/diary.html?storyid=5713 which may be applicable.

  • Half-open SYN Attack 3050.0

    Is there a trick to getting the signature 3050 ?half open syn flood? to produce an alert?
    The Cisco Intrusion Prevention System is on version 5.1(1p1) S229.0.
    We have tuned the signature to alert at 2048 half open connections.
    syn-flood-max-embrionic: 2048 default: 5000
    A ?show statistics virtual-sensor? shows that
    TCP streams currently in the embryonic state = 2871?
    but still no alert appears on the console.
    The signature use the normalizer engine and the event-action is set to ?produce-alert?
    Any help regarding this would be appreciated.

    What type of sensor are using?
    On the ASA-SSM-10 and ASA-SSM-20, the normalizer signatures will not be triggered (including the Syn Flood signature).
    The ASA-SSMs relie on the TCP Normalization features of the ASA itself to monitor for TCP anomalies including SYN Floods.
    For other sensors realize that the SYN Flood signature is tracked on a per server and per port basis. So with a 2048 setting there must be 2048 embryonic connections to a specific port on a specific server IP.
    The 2871 number you are seeing in the statistic is for ALL embryonic connections to ALL ports on ALL server IPs. If this is a deployed sensor it is unlikely that all 2871 embryonic connections from the statistics are to the same server IP/port.

  • Ping Flood - is this a security risk?

    In my Administration Security log file I have entries I do not understand.  Can anyone tell me what they might mean?
    SYN Flood - this is appearing one to three times a week for the last two months.

    IP packet w/MC or BC SRC addr - this appears about as often as Flood

  • OMG, my first real Lion problem: **SYS Flood

    I've run into my first Lion problem that I can't figure out, but maybe it's just a coincidence that it just started happening now, but I am getting these messages in my router security log:
    08/15/2011  19:13:09 **SYN Flood** 192.168.2.2, 55636->> 17.149.34.231, 5223 (from WAN Outbound)
    I am getting them from all devices hooked to the lan, i.e.. 2.2-2.x, and the IP listed is always mostly from an apple server! For example, in this case it's:
    Not sure what to do, as I can't find a setting in the router to stop checking for that, and if happens enough times, it clogs the router and I loose Internet connectivity. I am not running any torrent programs, but like I said it's issued across all devices on the Lan (even my lowly iPhone). Any ideas? thx!
    coocoo

    I have turned off options in the modem so it is not logged anymore.
    With further investigation I have found it occurs when the upload performance has dropped off. I seem to be get poor upload performance regularly, and I think there are dropped packets. If there is a dropped packet during the ack 3 way handshake, it would trigger a SYN Flood error.
    I don't know why the upload performance drops off.
    Perhaps someone on the same cable segment is running a file share server and taking all the bandwidth??
