ASA-5520 Monitoring Attacks
Hello ASA experts,
If you caught a syn flooding attacks against your ASA, what is the best approach to mitigate/prevent that from occuring? Also, what is the best method to monitor such attacks?
Best, ~sK
Thanks for the response! That's exactaly what we did; however, we enabled the scanning thread detection and implemented a threat-detection policy to shun any suspecious attacker.
We use Whatsup Gold and do have all of our ASAs monitored but don't have an snmp for the connection count. Can you please share the snmp active monitor used to monitor the connection count?
Much appreciated..
Best, ~sK

Scanning Threat Detection
Scanning Threat Detection is used in order to keep track of suspected attackers who create connections too many hosts in a subnet, or many ports on a host/subnet. Scanning Threat Detection is disabled by default.
Scanning Threat Detection builds on the concept of Basic Threat Detection, which already defines a threat category for a scanning attack. Therefore, the rate-interval, average rate (ARI), and burst rate (BRI) settings are shared between Basic and Scanning Threat Detection. The difference between the 2 features is that while Basic Threat Detection only indicates that the average or burst rate thresholds were crossed, Scanning Threat Detection maintains a database of attacker and target IP addresses that can help provide more context around the hosts involved in the scan. Additionally, only traffic that is actually received by the target host/subnet is considered by Scanning Threat Detection. Basic Threat Detection can still trigger a Scanning threat even if the traffic is dropped by an ACL.
Scanning Threat Detection can optionally react to an attack by shunning the attacker IP. This makes Scanning Threat Detection the only subset of the Threat Detection feature that can actively affect connections through the ASA.
When Scanning Threat Detection detects an attack, %ASA-4-733101 is logged for the attacker and/or target IPs. If the feature is configured to shun the attacker, %ASA-4-733102 is logged when Scanning Threat Detection generates a shun. %ASA-4-733103 is logged when the shun is removed. The show threat-detection scanning-threat command can be used in order to view the entire Scanning Threat database.

Cisco ASA 5520 Traffic monitoring
Hello ,
We have a Cisco ASA 5520 and im looking for a way to monitor largest outgoing and incoming traffic per ip in real time so to know which of my internal computers are using the most of our Internet Line. Is there a way to this through ADSM ? We use version 6.3.
Thanks a lotHi,
I dont think the ASA alone can give you a really clear picture of the real time situation.
It however should be able to give you some clue and simple statistics on the ASDM Firewall Dashboard
My ASDM version is 7.1 but it should be there in your version also. -
ASA 5520 Upgrade From 8.2 to 9.1
To All Pro's Out There,
I have 2 x ASA 5520 in Active/Standby state (Routed, Single context) running 8.2(3) image. They are working great and everybody is happy. Now it's time for us to upgrade to the latest and greatest version: 9.1 and as you know there are some architectural changes Cisco made to NAT statements and Access Lists. As one can tell, we have a monster environment in terms of NAT statements and access list that are currently configured on the appliances.
In order to make the upgrade process "less" painful, I was able to find a loaner ASA 5520 device so I can practice the upgrade process offline and if needed, I use it in production (in conjunction with existing Primary and Secondary devices) should it be helpful. I currently don't have any plans on how to move forward with these 3 devices and put together an smooth upgrade. I am asking advice from experts that perhaps have done this in the past and know some Do's and Don’ts and can provide me some options toward getting best result: Minimum downtime and Smooth upgrade.
I appreciate all the help in advance.Hi,
My personal approach from the start has been to learn the new NAT configuration format on the ASA CLI and manually convert the configurations for the new ASA software. I am under the impression that the automatic conversion that the ASA does by rebooting straight into a new software level causes quite a lot of configurations and they arent really optimal.
In your case it seems that you have a pretty much better situation than most people that dont have the chance to use a test device to test out the setup before actually putting it in production.
What you can basically do is
Insert the 8.2 configuration to the test ASA and boot it straight to the higher software levels and see what the conversion has done to the ASA configurations.
You can use "packet-tracer" command to test if correct NAT rules are still hit after the conversion
So far I have been lucky in the sense that most of the upgrades I have done have involved new hardware which has basically let me configure everything ready and just switch devices for the customer. So far everything has went really well and there has been only a 1-2 mistakes in NAT configurations because of misstyping some IP address or interface name which basically resulted from a lot of copy/paste when building the configurations. And these couple of mistakes have been from around 150 firewall migrations (of which most from FWSM Security Context to a ASA Security Context)
If you have time to put into this then I would suggest you try to learn the new NAT format and write your NAT configurations yourself. Converting the existing configurations should essentially give you the tools to then maintain that firewall configuration easily in the future and apply that knowledge elsewhere.
If you want to read a bit about the new NAT configuration format then I would suggest having a look at the NAT 8.3+ document I made:
https://supportforums.cisco.com/docs/DOC-31116
My personal approach when starting to convert NAT configurations for the upgrade is
Collect all NAT configurations from the current ASA including any ACLs associated with the Policy type NATs and NAT0 configurations
Divide NAT configurations based on type
Dynamic NAT/PAT
Static NAT
Static PAT
NAT0
All Policy Dynamic/Static NAT/PAT
Learn the basic configuration format for each type of NAT configuration
Start by converting the easiest NAT configurations
Dynamic NAT/PAT
Static NAT/PAT
Next convert the NAT0 configurations
And finally go through the Policy NAT/PAT configurations
Finally go through the interface ACLs and change them to use the real IP address as the destination in all cases since the NAT IP address is not used anymore. In most common screnarios this basically usually only involves modifying the "outside" interfaces ACL but depending if the customer has some other links to external resourses then its highly likely that same type of ACL changes are required on those interfaces also.
The most important thing is to understand how the NAT is currently working and then configure the new NAT configuration to match that. Again, the "packet-tracer" command is a great tool to confirm that everything is working as expected.
One very important thing to notice also is that you might have a very large number of Identity NAT configurations between your local networks interfaces of the ASA.
For example
static (inside,dmz) 10.10.10.0 10.10.10.0 netmask 255.255.255.0
In the new software you can pretty much leave all of these out. If you dont need to perform NAT between your local interfaces then you simply leave out all NAT configurations.
Naturally you can also use these forums to ask help with NAT configuration conversions. Even though its a very common topic, I dont personally mind helping out with those.
So to summarize
Try out the ASAs automatic configuration conversion when simply booting to new software levels on the test ASA you have
Learn the new NAT configuration format
Ask for help here on CSC about NAT configuration formats and help with converting old to new configurations.
Personally if I was looking at a samekind of upgrade (which I will probably be looking at again soon) I would personally do the following
Convert the configurations manually
Lab/test the configurations on an test ASA
During Failover pairs upgrade I would remove the Standby device from network, erase its configurations, reboot it to new software, insert manually written configurations.
Put the upgraded ASA to the device rack and have cables ready connected to the customer devices if possible (or use existing ones)
Disconnect currently active ASA running 8.2 and connect the new ASA to the network while clearing ARP on the connected routers to avoid any problems with traffic forwarding.
Test connectivity and monitor ASAs connection and xlate tables to confirm everything is working
Will add more later if anything comes to mind as its getting quite late here
Hope this helps

Cisco ASA 5520 Site-to-site VPN TUNNELS disconnection problem
Hi,
i recently purchased a Cisco ASA 5520 and running firmware v. 8.4(2) and ASDM v. 6.4(5)106.
I have installed 50 Site-to-Site VPN tunnels, and they work fine.
but randomly the VPN Tunnels keep disconnecting and few seconds after it connects it self automaticly....
it happens when there is no TRAFIC on, i suspect.
in ASDM in Group Policies under DfltGrpPolicy (system default) i have "idle timeout" to "UNLMITED" but still they keep disconnecting and connecting again... i have also verified that all VPN TUNNELS are using this Group Policie. and all VPN tunnels have "Idle Timeout: 0"
this is very annoying as in my case i have customers having a RDP (remote dekstop client) open 24/7 and suddenly it gets disconnected due to no traffic ?
in ASDM under Monitoring -> VPN .. i can see all VPN tunnels recently disconnected in "Login Time Duration"... some 30minutes, 52minutes, 40minutes and some 12 minutes ago.. and so on... they dont DISCONNECT at SAME time.. all randomly..
i dont WANT the VPN TUNNELS to disconnect, i want them to RUN until we manually disconnect them.
Any idea?
Thanks,

Cisco ASA 5520 Failover with DMZ
I have a pair of Cisco ASA 5520s running as a primary/standby. Everything is working properly with the primary ASA, however when I trigger a failover, everything works except for the DMZ interface on the standby ASA. I've poured over the configs, but perhaps I have been staring at them too long because I am just not seeing anything.

Does anyone see something I might be missing? I am at a loss...I'll just answer my own question...the configs are correct, but it the interface on the standby ASA was plugged into an improperly configured switchport. That'll do it everytime.

please could someone help.
Many thanksHello James,
You have configured the IPs on the interfaces incorrectly.
Let me point it out
failover
failover lan unit primary
failover lan interface SFO GigabitEthernet0/3
failover replication http
failover link SFO GigabitEthernet0/3
failover interface ip SFO 10.10.16.25 255.255.255.248 standby 10.10.16.26
You are telling the Primary device use IP address 10.10.16.25 and the secondary firewall will be 10.10.26.26
Now let's see the configuration on the Secondary Unit?
failover
failover lan unit secondary
failover lan interface SFO GigabitEthernet0/3
failover replication http
failover link SFO GigabitEthernet0/3
failover interface ip SFO 10.10.16.26 255.255.255.248 standby 10.10.16.25
On the secondary you are saying the primary IP will be 10.10.16.26 and the secondary will be 10.10.16.25
You have it backwards and based on the output I would say you configured it on all of the interfaces like that
So please change it and make it the same on all of the interfaces so both devices know the same thing ( which IP they should use when they are primary and secondary, this HAVE to match )
Hope that I could help

ASA 5520 with multiple contexts becomes unresponsive
Hi all. We have encountered a perculiar problem with a pair of our ASA 5520 firewalls with 2 contexts(each context being active on different ASA). What we are seeing is that sometimes when we have a sudden increase of inbound traffic(mostly HTTP) towards servers behind the firewalls they seem to go bananas for the lack of a better expression.
They become unaccessible via ssh and the traffic drops significantly. The problem is mitigated by disabling one of the monitored interfaces for failover(on one of the switches the firewall is connected to) so that both contexts become active on one firewall. After that the firewalls seem to come to their senses and we can enable the switch interface again but sometimes one of the pair needs to be rebooted to restore full funcionality.
To us it seems like there is a problem with failover and contexts but we haven't been able to pin it down. The failover link isn't stateful and when we tested the failover it works fine both ways with each ASA taking up the full load when the other ASA of the pair is not available.
Did anyone come across a similar situation with their firewalls?We are using ASA version 8.2(5).
The configuration of the failover is:

When I disabled the monitored interface it was always the same interface altough I believe the same effect could be achieved with disabling any of the monitored interfaces.
As for memory and CPU when it happens I cannot access the units to get a reading but I asume it's through the roof.
The thing that troubles me more is that the situation persists when the load drops and I have to perform the solution from the first post. One would assume that with the drop of the load that both firewalls would start to behave normally.
And I see that I haven't mentioned it before but when the load drops both units continue to handle traffic normally but I sometimes see as a side effect that I cannot SSH to one of the units. That unit usually has to be restarted. -
ASA 5520: Configuring Active/Standby High Availability
Hi,
I am new to Cisco firewalls. We are moving from a different vendor to Cisco ASA 5520s.
I have two ASA 5520s running ASA 8.2(5). I am managing them with ASDM 6.4(5).
I am trying to setup Active/Standby using the High Availability Wizard. I have interfaces on each device setup with just an IP address and subnet mask. Primary is 10.1.70.1/24 and secondary is 10.1.70.2/24. The interfaces are connected to a switch and these interfaces are the only nodes on this switch. When I run the Wizard on the primary, configure for Active/Standby, enter the peer IP of 10.1.70.2 and I get an error message saying that the peer test failed, followed by an error saying ASDM is temporarily unable to connect to the firewall.
I tried this using a crossover cable to connect the interfaces directly with the same result.
Any ideas?
Thanks.
DanThe command Varun is right.
Since you want to know a little bit more about this stuff, here goes a bit. Every interface will have a secondary IP and a Primary IP where the Active/Standby pair will exchange hello packes. If the hellos are not heard from mate, the the unit is delcare failed.
In case the primary is the one that gets an interface down, it will failover to the other unit, if it is the standby that has the problem, the active unit will declare the other Unit "standby failed). You will know that everything is alright when you do a show failover and the standby pair shows "Standby Ready".
For configuring it, just put a secondary IP on every interface to be monitored (If by any chance you dont have an available secondary IP for one of the interfaces you can avoid monitoring the given interface using the command no "monitor-interface nameif" where the nameif is the name of the interface without the secondary IP.
Then put the commands for failover and stateful link, the stateful link will copy the connections table (among other things) to avoid downtime while passing from One unit to another, This link should have at least the same speed as the regular data interfaces.
You can configure the failover link and the stateful link in just one interface, by just using the same name for the link, remember that this link will have a totally sepparate subnet from the ones already used in firewall.
This is the configuration
failover lan unit primary
failover lan interface failover gig0/3
failover link failover gig0/3
failover interface ip failover 10.1.0.1 255.255.255.0 standby 10.1.0.2
failover lan unit secondary
failover lan interface failover gig0/3
failover link failover gig0/3
failover interface ip failover 10.1.0.1 255.255.255.0 standby 10.1.0.2
Make sure that you can ping each other secondary/primary IP and then put the command
failover first on the primary and then on the secondary.
That would fine.
Let me know if you have further doubts.

Asa 5520 | CPU Spikes above 90% for 5 Seconds then it went down to 35 - 40%
Hi Experts
i have ASA 5520 , some times the CPU Spikes above 90% for 5 Seconds then it went down to 35 - 40% ,but what happened when it shoots to 90% all connection go through this ASA gets drops then i receive complain since application traffic traverse this FW ,so how can i see the CPU History for last 1 week , i need to see the times and the date WHEN THE CPU went above 90% for 4 seconds
thanks
jamilHi Ibrahim,
from he ASA you would not be able to pull data for last one week, you would need an SNMP server or anyother monitoring server for pulling reports.
For high CPU issues, I would suggest opening a TAC case for it, since it requires detailed investigation and access to your box. Just as in initial pointer, these outputs might help you identifying the cause:
show proc cpu-usage
show traffic
show conn count
show interface
Remember these outputs are useful only if they are from the time of the issue, check what traffic is hogging the CPU and if the ASA is being overwhelmed or not.
Thanks,
Varun Rao

ASA 5520 IP range block or Country IP block
hi,
i need help on ASA 5520 and i would like to block countries IP address from the attack, there is any way to block countries ip address or range ip address .
Thanks,
RabihI've created a script where you chose an authority by selecting in a menu and it'll give you the configuration to drop into the ASA.
https://github.com/in-transit/regional-asa
You can block or allow a specific region if you want. I'll be upgrading it to do specific countries but now it does authorities like ARIN, RIPE, APNIC, etc. -
Security Manager traceroute ASA 5520
How can I use Security Manager (3.2) to configure a ASA 5520 to show up in a traceroute, have found a doc on how to do this from the cmd line but would prefer to keep everything in CSM.
MikeThere used to be a similar bug in IDM.
The sensor itself does not declare an interface as promiscuous.
SO CSM has to intepret the configuration to determine if the interface is promiscuous.
On an Appliance an Interface is InLine only if it is configured as part of an InLine Interface Pair, or has InLine Vlan Pairs assigned.
So CSM makes the assumption that if it is not part of an InLine Interface Pair and does not have InLine Vlan Pairs created, but is active and being monitored by a virtual sensor then it must be Promiscuous.
And the above is True for Appliances.
What the CSM developers may not have realized is that this is NOT true for Modules.
For most modules like the AIP-SSMs, the sensor is configured to monitor the interface, but there is nothing in the module configuration itself that tells you whether it is inline or promiscuous.
That knowledge is only within the configuration of the ASA chassis itself.
CSM is simply incorrectly using the rules for Appliances against the SSMs.
This was corrected in IDM by always just marking the SSM port as "monitored" if I remember right and not trying to specify whether it is promiscuous or inline.
CSM would likely have to make the same change, and just then just tell the user they need to check ASA configuration to determine whether or not the ASA is configured to send packets to the SSM promiscuously or inline.

What about translating the traffic on the local ASA (Active unit) for traffic received from the VPN tunnel to the internal interface IP address? You can try something like nat (outside,inside) source dynamic obj-VpnRemoteTraffic interface destination static StandbyIP StandbyIP

DHCP question on VPN to ASA 5520
Our VPN uses the Microsoft VPN client to connect to an ASA 5520 running 8.0(3). Clients get address from our internal DHCP server. How do I get the ASA to send the client computer name in the DHCP request, rather the the group name and some number it appends to it? This is an issue for us because those entries show up as "rogue" registrations in DNS, because they don't match our naming structure.
Make sure if the client is forwarding it's name in the DHCP messages. Parameters can't be added at ASA.

Site to Site VPN between Cisco ASA 5520 and Avaya VPN Phone
Hi,
I am wondering if anyone can assist me on configuring Cisco ASA 5520 site to site vpn with Avaya VPN Phone? According to Avaya, the Avaya 9630 phone acts as a VPN client so a VPN router or firewall is not needed.
The scanario:
Avaya System ------ ASA 5520 ------ INTERNET ----- Avaya 9630 VPN Phone
Any help or advice is much appreciated.
Thanks.Hello Bernard,
What you are looking for is a Remote Ipsec VPN mode not a L2L.
Here is the link you should use to make this happen:)

Multiple Public IP's on ASA 5520
Hi,
I have ASA 5520 with Ver 8.2.
Outside interface is directly connected to ISP's router(TelePacific) and is assigned one of public IP:198.24.210.226.
There are two servers inside the network with the private IP's:192.168.1.20 for DB Server, and 192.168.1.91 for Web Server.
I did Static NAT 198.24.210.226 to 192.168.1.20 and 198.24.210.227 to 192.168.1.91.
When I access DB Server(198.24.210.226) it's working OK but when I access Web Server(198.24.210.227) there is no response at all.
I checked the inside traffic, it even did not get into the firewall.
Is this the problem with ISP's router? How can we route all of our public IP's to the outside interface(198.24.210.226)?

You seen to have an /29 public subnet. You should be able to use IP addresses from this subnet to configure NAT on your firewall. I dont think you need any specific configurations to allow the usage of the whole subnet as NAT IP addresses.
You can naturally check the following
show run sysopt
Check that you DONT have the following
sysopt noproxyarp outside
At the moment you are not actually configuring Static NAT but rather Static PAT.
You are only forwarding some ports from certain public IP addresses to the local IP address. If you were doing Static NAT, then you would actually be staticly binding the public IP addresses to the local IP address. So it would apply to any TCP/UDP port and you would only need to use the ACL to allow traffic.
Though in that case you would have to replace the .226 IP address with something else as its the firewall interface IP address and it should not be assigned to be used by a single host on the LAN usually.
If you wanted to staticly assing public IPs to both of these servers you could do
static (inside,outside) 198.24.210.227 192.168.1.91 netmask 255.255.255.255
static (inside,outside) 198.24.210.228 192.168.1.10 netmask 255.255.255.255
access-list OUTSIDE-IN extended permit tcp any host 198.24.210.228 eq 3389
access-list OUTSIDE-IN extended permit tcp any host 198.24.210.228 eq 9070
access-list OUTSIDE-IN extended permit tcp any host 198.24.210.227 eq 3389
access-list OUTSIDE-IN extended permit tcp any host 198.24.210.227 eq 80
