When Cyber Awareness Is Fundamentally Lacking

"Smartphones (and tablets, WdN) are invading the battlefield", reports the Economist on its website of 8 October 2011. On the same day the hacking of U.S. drones is reported on by several news sites. ("They appear friendly". Keyloggers???) Is this a coincidence? more

WannaCry Ransomware Cyberattack Spreading to Countries Across the World, 45K Attacks Reported So Far

Security researchers are reporting a massive attack today, dubbed "WannaCry", which has reached 45,000 attacks in 74 countries around the world so far, mostly in Russia. more

Security and Reliability: A Closer Look at Vulnerability Assessments

Building on my last article about Network Assessments, let's take a closer look at vulnerability assessments. (Because entire books have been written on conducting vulnerability assessments, this article is only a high level overview.) What is a vulnerability assessment? more

The Advanced Persistent Threats (APT) Deception

Most of the good thrillers I tend to watch have spies and assassins in them for some diabolical reason. In those movies you'll often find their target, the Archduke of Villainess, holed up in some remote local and the spy has to fake an identity in order to penetrate the layers of defense. Almost without exception the spy enters the country using a fake passport; relying upon a passport from any country other than their own... So, with that bit of non-fiction in mind, why do so many people automatically assume that cyber-attacks sourced from IP addresses within China are targeted, state-sponsored, attacks? more

Security Experts, Privacy Advocates Hopeful Rollout of 5G Can Eliminate Surveillance Vulnerabilities

Security experts and privacy advocates see the rollout of the new 5G wireless network as a possible solution to eliminate surveillance vulnerabilities that allow spying on nearby phone calls. more

In Network Security Design, It’s About the Users

One of the longstanding goals of network security design is to be able to prove that a system -- any system -- is secure. Designers would like to be able to show that a system, properly implemented and operated, meets its objectives for confidentiality, integrity, availability and other attributes against the variety of threats the system may encounter. A half century into the computing revolution, this goal remains elusive. more

Australia Booting Infected Computers Off Their Networks

The Australian has a good article describing the efforts some of their ISPs are making in an attempt to clean up their act: the government is encouraging ISPs to detect computers on their network that are infected and part of botnets, and to communicate to the customer that their system is compromised... Unless the customer feels a little bit of pain they will not change their ways. more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 3)

Previous posts (Part 1 and Part 2) offer background on DNS amplification attacks being observed around the world. These attacks continue to evolve. Early attacks focused on authoritative servers using "ANY" queries for domains that were well known to offer good amplification. Response Rate Limiting (RRL) was developed to respond to these early attacks. RRL, as the name suggests, is deployed on authoritative servers to rate limit responses to target names. more

According to the Department of Homeland Security, Cybercrime Is a Bigger Threat Than Terrorism

An article in Forbes the other day reports on US Secretary of Homeland Security Janet Napolitano's comments that 'cybercrime represents the "greatest threat and actual activity that we have seen aimed at the west and at the United States" in addition to "or other than Al Qaeda and Al Qaeda-related groups."' ..."Napolitano cited a study commissioned by Symantec that put the total worldwide cost of cybercrime at $388 billion -- higher than the global market for heroin, cocaine and marijuana combined." more

At the Start of the NL IGF

At the annual Dutch "delegation" dinner at the Internet Governance Forum (IGF) in Vilnius, Lithuania, I voiced that it may be a good idea to start a Dutch IGF. This followed a discussion in which we discussed the possibilities of involving more people and organisations from the Netherlands in Internet governance. The, now, Ministry of Economic Affairs, Agriculture and Innovation followed this thought and made it possible for the ECP/EPN foundation to start the NL IGF. more

An Update From CIRA on IoT Security

Last April, I shared information about a multistakeholder process that CIRA is part of, which seeks to identify and guide the development of policy around the Internet of Things (IoT), putting security at the heart of internet innovations in Canada. Since the formation of this process, we've made quite a bit of progress and I'm pleased to share some of that with you. more

Securing the Routing System at NANOG 74

The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If the attention on this topic at NANOG 74 is anything to go by we seem to be experiencing a local peak. more

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." more

Malware and Botnet Operators Setting Up Their Own Data Centers

Dennis Fisher of Thread Post reports: "The malware writers and criminals who run botnets for years have been using shared hosting platforms and so-called bulletproof hosting providers as bases of operations for their online crimes. But, as law enforcement agencies and security experts have moved to take these providers offline, the criminals have taken the next step and begun setting up their own virtual data centers." more

Why More Effort Won’t Solve the Exceptional Access Problem

In the debate over government "exceptional access" to encrypted communications, opponents with a technical bent (and that includes me) have said that it won't work: that such a scheme would inevitably lead to security problems. The response -- from the policy side, not from technical folk - has been to assert that perhaps more effort would suffice. FBI Director James Comey has said, "But my reaction to that is: I'm not sure they've really tried." Hillary Clinton wants a "Manhattan-like project, something that would bring the government and the tech communities together". More effort won't solve the problem - but the misunderstanding lies at the heart of why exceptional access is so hard. more
