DDoS default settings

jhoffma_3

Hi,

my question is: Which default settings are done on a Cisco ASA and a CISCO ASR (with firewall IOS) against DDoS attacks?

The Cisco ASR is configured as zone based firewall, which inspect all pakets.

I read the article

http://www.cisco.com/en/US/docs/ios-xml/ios/sec_data_zbf/configuration/xe-3s/asr1000/sec-ddos-attack-prevn.html and wanted to know, what the device will do aiganst DDoS attacks, if I don't configure the settings from the "

Protection Against Distributed Denial of Service Attacks" guide.

Could you explain that for me?

Thanks in advance!

Hi Julia,

Check the following links for further information

http://www.cisco.com/en/US/docs/security/asa/asa82/configuration/guide/conns_threat.html

http://www.cisco.com/en/US/products/ps6120/products_tech_note09186a00809763ea.shtml

We also have the normalizer inspection provided by the ASA that will inspect each tcp packet and make sure it conforms to the RFC,etc,etc,etc,etc

For the IOS firewall

Does are the defaults that I could think at this moment,
