Security and Reliability: A Closer Look at Penetration Testing

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.

Civil Society Hung Out To Dry in Global Cyber Espionage

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.

Reducing the Risks of BYOD with DNS-Based Security Intelligence; Part 2: Taking Control

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.

EC3, the European Cybercrime Centre, Opened - Challenges All Around

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.

Exploits, Curdled Milk and Nukes (Oh my!)

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?"

WCIT’s Security Issues

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.

Raspberries! Botnet Spam Just Got a Whole Lot More Dangerous

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.

When Businesses Go Dark: A DDoS Survey

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.

The Recent DDoS Attacks on Banks: 7 Key Lessons

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."
