Hacktivists on Jan. 22 threatened more DDoS attacks against U.S. banks and claimed they recently hit three institutions. Despite banks' improvements in staving off online outages, the longevity of the attacks is concerning, experts say.
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.
ENISA, the European Union cyber-agency, is out with its first-ever Threat Landscape report. What are the emerging threats and vulnerabilities, and how should organizations globally respond to them?
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.

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.
To repel the onslaught of cyberattacks against organizations, security leaders are debating the merits of the "hack back" defense. Legal experts discuss the pros and cons of this emerging strategy.
U.S. banks are improving efforts to thwart distributed-denial-of-service attacks. But they're struggling to find the balance between informing customers and giving attackers too much publicity.
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.
