Real tales of cyberattack response and recovery are hard to come by because organizations are reluctant to share details for a host of legitimate reasons, not the least of which is the potential for negative financial fallout. However, if we never tell our stories we doom others to blindly walk our path. Better to share our real-world battlefield experiences and become contributors to improved threat intelligence.
Juniper Networks has added a new way for its anti-DDoS appliance to mitigate what's known as massive UDP-based amplification attacks that typically work by exploiting compromised servers of different kinds to both spoof and vastly increase the denial-of-service barrage.
The list of DDoS attacks in the month of June has made for grim reading. High-profile sites have been targeted by extortion demands, online games got disrupted and at least one company was put out of business as a direct result.
Cheating gamers pay as little as $10 per month to launch denial of service attacks against their opponents as a tactical advantage using commercial providers that walk the line between being legitimate businesses that stress-test their customers' networks and purveyors of DDoS as a service, researchers at USENIX Security 2013 say.
A new class of enormous DDoS attacks emerged March 26 with a DNS reflection attack by email spammer CyberBunker against anti-spam service Spamhaus. The reported traffic peak of 300Gbps was double the previous record.
A Cisco-funded router startup has unveiled its first product, which the company says implements breakthrough silicon-to-photonics circuitry for scaling service provider networks and enabling them for software-defined networking (SDN).
Cisco has begun streamlining distributed denial-of-service (DDoS) attack defense by offering Arbor Networks technology on its carrier class routers.
The security issues affecting businesses are similar around the world. Most involve employees innocently bringing an infected personal mobile device into the corporate network, or clicking on a social media link that looks harmless but hides a Trojan or worm that will secretly steal data and money and, potentially, remain undetected with severe impact on security of the infected device.
Web acceleration company Akamai today announced Version 2.0 of its Kona Site Defender service, which adds new ways for clients to protect themselves against denial-of-service attacks.
Our team at Nominum recently looked at the biggest threats to fixed networks at the DNS layer. Why the DNS layer? Because it is ubiquitous -- every network runs on it -- and it is the best option for protecting critical infrastructure.
Juniper Networks has acquired the assets of Webscreen Systems, a developer of distributed denial-of-service (DDoS) mitigation products, from Accumuli of the United Kingdom.
For all the advances in enterprise networking over the years there's been one big step backward: security testing. Relatively few enterprises today conduct regular security tests in-house, relying instead on occasional tests by outside consultants or, more dangerously, just taking vendor claims at face value.
An intrusion prevention system (IPS) includes all the features of an intrusion detection system but also has the ability to act upon malicious traffic. Since the IPS usually sits in line with network traffic it can shut down attacks, typically by blocking access from the attacker or blocking access to the target. In some cases, the IPS can talk to the firewall to block an attack.
Enterprise product in the making and ‘loved’ by disbanded hacker group LulzSec.
The constant and very real threat of distributed denial of service
(DDoS) attacks aimed at headline grabbing “hacker” groups, such as
Lulz Security and Anonymous, have helped one tech start-up pick up new
business.
For the second day in a row, blog-hosting giant WordPress.com suffered a distributed denial-of-service attack that it was able to cut off quickly. The motive remains a matter of speculation.
