Banks have improved DDoS defenses, but ensuring ongoing online reliability requires a more offensive measure - one that rids the Internet of vulnerable sites that can too easily be used for bot traffic.
Independent monitoring shows U.S. banks doing a better job of deflecting DDoS attacks. Nevertheless, DDoS expert John Walker says the attackers continue to represent "a growing threat" to all organizations.
"A year ago, quite frankly, the capability was not there," DHS Deputy Undersecretary for Cybersecurity Mark Weatherford says. "We did not have the capacity to collaborate nearly as effectively as we do now."
How are banks responding to DDoS phase 2? "From a technology standpoint, we have improved our defenses quite a bit," says Dan Holden of Arbor Networks. Experts discuss top DDoS lessons banks have learned.
Which fraud trends need the most attention from U.S. banking institutions in 2013? Distributed-denial-of-service attacks and account takeover, says FS-ISAC's Bill Nelson, who offers fraud-fighting tips.
To mitigate the top threats for 2013, organizations need to understand the motivations of potential attackers so they can adequately defend their networks and systems. Experts describe risk management strategies for the year ahead.
The hacktivist group Izz ad-Din al-Qassam Cyber Fighters claims that its second phase of distributed-denial-of-service attacks has affected nine banks since Dec. 11, and it warns more attacks are on the way.
A distributed denial of service attack (DDoS) occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers. This is the result of multiple compromised systems (for example a botnet) flooding the targeted system(s) with traffic.
Hacktivists on Christmas Day announced new plans for more DDoS attacks against U.S. banks, and it appears Citi was among the first hit, although the attackers named no specific targets in their latest threat.
PNC and Wells Fargo both reported only minor disruption from online traffic surges on Dec. 20. Has the strength of DDoS attacks subsided, or are banks getting better at defending against these strikes?
