Cisco Firewall :: Launch LAND Attack Against Firewall ASA 5520

Apr 15, 2013

I try to launch a LAND Attack against my firewall ASA 5520. Everything will work fine. But why, I think it should not work. I use a little tool where I can user a spoofed address, with a cluster shell and attack the firewall interface with the source of 127.0.0.1 ore the ip address of the interface as the source and destination. Then I get a cpu load of 89% with only two host. With IP tables I can use kernel processes to prevent this. But I don´t find anything for ASA.

Cisco :: 4402 Light Weight APs Drop Out After Land Attack

Sep 12, 2012

We have a WLAN consisting of a WLC 4402 and 11 lightweight APs. For security/compliance reasons we have a Cisco PIX firewall that sits between the WLC (outside) and the APs (inside). The APs are allowed to form LWAPP tunnels through the firewall (inside access-list) to the WLC and the WLAN works as expected.The firewall then limits traffic from the WLAN (outside access list) to certain the internal systems.I have noticed that every so often the firewall logs show continuous "Land attack from 0.0.0.0 0.0.0.0" messages then all APs are disconnected (all lights flash).

Cisco Firewall :: ASA 8.4 / Receive Alerts On Connection Threshold

Oct 4, 2012

On a Cisco ASA 8.4 code is it possible to receive an alert once a certain number of tcp/udp connections is reached?  I'd like to see if I can get an email alert or syslog if the ASA reaches say 2,000 connections for example.  Once I get an alert I could then investigate the cause of so many connections.

Cisco Firewall :: PIX 525 Anti-Spoofing Attack Protection

Mar 19, 2011

I have multiple questions about the PIX 525 software version 8.0(2) ASDM 6.0 (2)I am a windows network admin that is new to Cisco and routing in general. I have read through the forums and the Cisco documentation, but have not been able to fully understand the topics discussed within.

1. Anti-Spoofing Attack Protection
2. Scanning Threat Detection - Auto Shun
3. NTP Sync Verification
4. QoS implementation5. IOS and ASDM Backup
 
This option is currently DISSABLED for all interfaces.I know what ip address spoofing is, but what is the functionality of these options specifically? How does it work and should I enable it and for which interfaces? Second Question: Scanning Threat Detection - Auto Shun
 
I found this option in ASDM under: Configuration --> Firewall --> Threat Detection.Enable Basic Threat Detection and Enable Scanning Threat Detection are both currently ENABLED, but Shun Hosts detected by scanning threat is currently DISABLED. Also, the Networks Excluded from Shun field is empty. I know what the shun command does. I have used it many times when I have been fortunate enough to catch some piece of **** trying to spam my mail server or gain access to it.
 
What I am asking specifically is how does the Auto Shun work? Should I enable it and what are the potential consequences? Also, what exactly is a scanning attack?
 
I am not familiar enough with the PIX and with the topics discussed in the document to successfully apply the info within. Plus, I'm not sure it covers the kind of basic, all-inclusive bandwith cap I would like to put in place.
 
The goal is to cap the maximum internet (outside) bandwidth that inside5 can use to a reasonable percentage while allowing the other interfaces to have the remainder.

How would I go about this implementation? 2. Is there a way to allow inside1 - inside4 to use max bandwidth when there is no traffic on inside5?
 
I am probably, at least, the third owner of this device and I do not have an account with Cisco nor can my tiny (perhaps non-exsistant given the current economic state) IT budget afford any form of support or software licensing with them.My goal is to backup the IOS and ASDM data in the event that I have to replace the device due to a hardware failure.
 
I found a file transfer function within ASDM which allowed my to copy the files pix802.bin, asdm-602.bin and tfp from flash to my desktop computer. I also have a copy of the activation key info and my current configuration.
 
1. Have I backed up all the data/info I would need to restore this software and ASDM to another unit.
2. The activation key screen also has a serial number field. Is this the hardware serial number or is it for the software? and is it tied to this device specifically or can I use it to restore another unit if necessary?
3. Is there anything else I should do or be aware of regarding backup and restore for the PIX?
4. What is the tfp file?

Cisco :: Unidentified Traps And Interface Down Alerts LMS 4.2

Feb 4, 2013

Sometimes we have unidentified traps in our log, we don't know where they come from.
 
In high severity faults we see an active alert with device name “Unidentified” event name unresponsive but with a certain ip address.
 
What are these alerts about? Can I filter them?,A second issue I have is that I get interface down alerts. But when we log on to the device, there is no interface down at all. We can also ping the device from the lms server at that time. I have been told that the admin state and operational state has to be up.

Cisco Wireless :: WAP4410N Email Alerts - Where To Put From Address

May 27, 2011

From the WAP4410N admin pages or console you can enable e-mail alerts. You have to set the essential TO address and mail server address. Where can I put the FROM address ? From what I can see it uses the hostname value as from address. The hostname in my case is ap02. Then you could try setting a mail address in the hostname field, but thats not allowed.

Cisco :: 4404WLC - Causing DOS Attack Several Times A Day

Feb 12, 2013

I manage a CISCO 4404 WLC with about 46 access points across our WAN. System works very well, serving trusted users, guests etc very well.However, over the last month or two we have had an issue where we have had high load on our WAN.We have traced this down to the CISCO 4404, about 3-4 times a day, the controller connects to every access point and transmits about 5-8mb of data on port 5427. This in itself would not be a problem, but it connects to all 46 at the same time.

DDOS Attack - How To Change IP Address

Jun 29, 2012

I am wondering how to change my internet IP address as someone is DDOS attacking me on a daily basis. I have tried all the ipconfig stuff, and unplugged my modem for an hour. Not sure what to do at this point. Plugging my PC directly to the modem changes my IP, but then when I plug my PC back into my router, it changes back.

Home Network :: How To Block A DDOS Attack

Feb 2, 2012

Is there anyway to block a DDOS attack? I dont know to much about DDOS attacks and how they work, but i think i understand a little bit of it. Is there no way to configure a firewall to detect rapid, spontaneous,continuous amounts of fragmented, random data coming from an IP address? Wouldn't the data coming in from a DDOS server be somewhat distinct from data that flows normally

D-Link DIR-615 :: Xmas Port Scan Attack From WAN

Jan 21, 2011

I'm on my 3rd Virgin media 615 today, the last one arrived yesterday and I opened the box to fine a rev d with old bios installed, throw hands in air and all that and then proceeded to upgrade to 4.13 which I have found to be stable and work ok, the other two grow to have the wireless failure issue, I could moan here about VM but hey there's no point so I have come here for adviseafter I found the last one wireless going down, daily trips from the kids down to me to ask why the internet isn't working etc etc I started to investigate, I found the 4.13 and gened up a bit, looked at the 3rd party code and came back to Dlinks own code, anyway I have seen in the last few days hundreds of similar port scans. [code]

Now is the the router being a little sensitive to harmless software companys scans to see if products installed etc or are they something to worry about now I know whats going on if its the latter, and I don't think anyones got in yet but I would like to ban these ip's and to be honest I'm not sure of the best way also I noted a UDP active session that not a part of my subnet too mine being a standard 192.168.0.*and the other being 192.168.4.*.

Cisco WAN :: 2801 IOS / Simulating ICMP Redirecting Attack On Laboratory Network

Oct 14, 2012

I study at University of Ostrava and currently I am working on my master thesis. Its content is realization of few attacks on network. Now I am trying to implement ICMP redirecting attack by using Intercepter program. Diagram of my netwok you can see on enclosed picture (Schema.jpg). Through Intercepter program I generate packets ICMP redirect (ICMP type 5), which are successfully sent from PC Attacker, but these packets do not arrive to PC Victim and Warshark shows me messages „ Destination Unreachable (Host Unrecheable).“ When I use instead of Cisco switch non Cisco switch (for example: Edimax) or hub, ICMP redirects packets arrive to PC Victim and I can continue in the attack?
 
SW:
Switch is in the defautl setting
Cisco Catalyst 2960 IOS: c2960-lanbasek9-mz.122-50.SE3.bin
Router:
Set only IP address on FastEthernet interfaces
Cisco 2801 IOS: 2801-ipbasek9-mz 124.25f.bin

Cisco Firewall :: ASA 5510 / Multiple VLANs Behind Single Firewall Segment?

Feb 5, 2012

I need to create a firewalled segment that not only separates hosts from general population, but also from each other.  The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible.  1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
 
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9 

This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).
