ICANN has released a set of guidelines to explain its Coordinated Vulnerability Disclosure Reporting. The guidelines serve two purposes, says ICANN: "They define the role ICANN will perform in circumstances where vulnerabilities are reported and ICANN determines that the security, stability or resiliency of the DNS is exploited or threatened. The guidelines also explain how a party, described as a reporter, should disclose information on a vulnerability discovered in a system or network operated by ICANN." more
As noted in my first article of this series (see part one, two and three), security and reliability encompass holistic network assessments, vulnerability assessments and penetration testing. This month I'd like to go deeper into penetration testing; however, first, let's go back for a quick refresh before getting started. more
This post was co-authored by Sarah McKune, a senior researcher at the Citizen Lab. Public attention to the secretive world of cyber espionage has risen to a new level in the wake of the APT1: Exposing One of China's Cyber Espionage Units report by security company Mandiant. By specifically naming China as the culprit and linking cyber espionage efforts to the People's Liberation Army, Mandiant has taken steps that few policymakers have been willing to take publicly, given the significant diplomatic implications. more
In part 1, I talked about some of the risks associated with BYOD. But there are actions you can take to greatly reduce this risk. One effective method for limiting the risk of BYOD is to employ DNS-based security intelligence techniques. DNS-based security intelligence makes use of an enterprise's caching DNS server to monitor and block DNS queries to known botnet command and control (C&C) domains. more
On Friday 11 January 2013 the European Cybercrime Centre, EC3, officially opened its doors at Europol in The Hague. If something shone through from the speeches of the panel participants, it is that there are tight budget restraints and a strong wish to cooperate with the U.S., the Interpol centre in Singapore and Russia. Let me share my thoughts on expectations. more

Throughout the second half of 2012 many security folks have been asking "how much is a zero-day vulnerability worth?" and it's often been hard to believe the numbers that have been (and continue to be) thrown around. For the sake of clarity though, I do believe that it's the wrong question... the correct question should be "how much do people pay for working exploits against zero-day vulnerabilities?" more
Distributed denial-of-service (DDoS) attacks that targeted U.S. financial institutions this week have reached 60 Gbps, according to researchers from DDoS mitigation provider Arbor Networks. more
Another contentious issue at the WCIT in Dubai is 'security'. There has been a dramatic increase in nervousness regarding a whole range of security issues, especially in relation to the internet. They include: SPAM, denial-of-service-attacks, identity theft, cybercrime, cyberwarfare, and privacy issues on social media. From the list above it is clear that some of these issues are related to content, while some can be classified as national security and others as criminal offences. In other words, there is no clear-cut issue on what constitutes security. more
Many have heard of botnets, but for those that aren't certain what they are: Botnets are armies of hacked zombie computers that have malware on them, and send spam email at the command of operators anywhere in the world. They can also be told to deploy denial of service attacks, by all hitting the homepage of a given company, or attacking the DNS server or a service or country. more
SANS has announced NetWars CyberCity, a small-scale city located close by the New Jersey Turnpike complete with a bank, hospital, water tower, train system, electric power grid, and a coffee shop. NetWars CyberCity was developed to teach cyber warriors from the U.S. Military how online actions can have kinetic effects. more
In February 2012, Neustar surveyed IT professionals across North America to better understand their DDoS experiences. Most were network services managers, senior systems engineers, systems administrators and directors of IT operations. In all, 1,000 people from 26 different industries shared responses about attacks, defenses, ongoing concerns, risks and financial losses. more
Starting in mid-September, one of the largest and most sophisticated DDoS attacks ever targeted the titans of American banking. Initially, victims included Bank of America, JPMorgan Chase, Wells Fargo, PNC Bank, and U.S. Bancorp. In the weeks to come, others would also feel the pain. Websites crashed, customers were unable to make transactions and IT professionals and PR gurus went into panic mode. Leon Panetta, U.S. Secretary of Defense, said the attacks foreshadowed a "Cyber Pearl Harbor." more
If there's one simple - high impact - thing you could do to quickly check whether your network has been taken over by a criminal entity, or uncover whether some nefarious character is rummaging through your organizations most sensitive intellectual property out of business hours, what would it be? In a nutshell, I'd look to my DNS logs. It's staggering to me how few security teams have gotten wise to regularly interrogating the logs from their recursive DNS servers. more
A cooperative international report was released last week outlining Internet and mobile best practices aimed at curtailing malware, phishing, spyware, bots and other Internet threats. It also provides extensive review of current and emerging threats. "Best Practices to Address Online and Mobile Threats" is a comprehensive assessment of Internet security as it stands today... more
