Usernames/email addresses and encrypted passwords for profile accounts created on the ICANN.org public website have been obtained by an unauthorized person, the Internet Corporation for Assigned Names and Numbers announced Wednesday night. more
In my last blog post I shared some of the general security challenges that come with the Internet of Things (IoT). In this post, I will focus on one particular security risk: distributed denial of service (DDoS) attacks. Even before the age of IoT, DDoS attacks have been turning multitudes of computers into botnets, attacking a single target and causing denial of services for the target's users. By "multitudes" we can be talking about thousands or even millions of victim devices. Now add IoT into the equation... more
Shadow IT -- the use of unsanctioned software and services by employees -- is a problem. It's a big one. According to Forbes, 72 percent of executives don't know how many "shadow" apps are being used on their network. Beyond overloading network resources and impacting data compliance, there is also the real threat of security breaches from unapproved apps. Managing IT you can't see is no easy task, but fortunately it's not impossible. Here are five tips to help bring light to the shadows. more
Over the last few years I've been hearing some people claim that botnets are the real spam problem and that if you can find a sender then they're not a problem. Much of this is said in the context of hating on Canada for passing a law that requires senders actually get permission before sending email. Botnets are a problem online. They're a problem in a lot of ways. They can be used for denial of service attacks. They can be used to mine bitcoins... more
Today the Internet Technical Advisory Committee (ITAC) to the OECD published the fifth edition of its newsletter. The ITAC was created in 2009 following the OECD's Seoul Ministerial with the objective to provide Internet technical and policy expertise to the work of the OECD on Internet-related issues. This informal group is coordinated by the Internet Society and currently counts 28 members active in domains such as open Internet/Web standards development, interconnection, IP addressing, security or privacy. more
Unlike consultant-led penetration testing, periodic or continual vulnerability scanning programs have to operate harmoniously with a corporation's perimeter defenses. Firewalls, intrusion prevention systems, web proxies, dynamic malware analysis systems, and even content delivery networks, are deployed to protect against the continuous probes and exploit attempts of remote adversaries -- yet they need to ignore (or at least not escalate) similar probes and tests being launched by the managed security service providers an organization has employed to identify and alert upon any new vulnerabilities within the infrastructure or applications that are to be protected. more
The indicators of compromise (IOCs) outlined in my last blog post can be used as a baseline for developing intrusion sets and tracking attack campaigns and threat actors. When launching an attack, threat actors use a variety of vectors and infrastructure, which Verisign iDefense analysts -- as well as analysts across the cybersecurity community -- correlate to group attacks, tracking actors and determining attack methods. more
To those of us who have worked on crypto policy, the 1990s have become known as the Crypto Wars. The US government tried hard to control civilian use of cryptography. They tried to discourage academic research, restricted exports of cryptographic software, and -- most memorably -- pushed something called "escrowed encryption", a scheme wherein the government would have access to the short-term keys used to encrypt communications or stored files. more
What are the most pressing Internet governance issues in the next 2-5 years? What are the biggest priorities in terms of making the Internet more secure and trusted? What are the best ways to bring the next 3 billion people online? Those will all be topics of discussion at the "InterCommunity 2015" meeting taking place this week on July 7 and 8. The meeting will not take place at any one physical location... more
I previously provided a brief overview of how Verisign iDefense characterizes threat actors and their motivations through adversarial analysis. Not only do security professionals need to be aware of the kinds of actors they are up against, but they should also be aware of the tactical data fundamentals associated with cyber-attacks most commonly referred to as indicators of compromise (IOCs). Understanding the different types of tactical IOCs can allow for quick detection of a breach... more
Where has DNSSEC been successful? What are some current statistics about DNSSEC deployment? What are examples of innovations that are happening with DNSSEC and DANE? All of these questions will be discussed at the DNSSEC Workshop at ICANN 53 in Buenos Aires happening on Wednesday, June 24, 2015, from 09:00 – 15:15 Argentina time (UTC-3). You can watch and listen to the session live. more
What do Europeans interested in Internet policy think about cybersecurity, network neutrality, IANA, improving Internet access and other topics? Tomorrow the second day of the European Dialog on Internet Governance (EuroDIG) 2015 in Sofia, Bulgaria, will cover all those topics and many more. I've listed some of the sessions that either I or my Internet Society colleagues are participating in. I will personally be involved as a panelist on the two sessions about cybersecurity. more
Facebook just announced support for PGP, an encrypted email standard, for email from them to you. It's an interesting move on many levels, albeit one that raises some interesting questions. The answers, and Facebook's possible follow-on moves, are even more interesting. The first question, of course, is why Facebook has done this. It will only appeal to a very small minority of users. Using encrypted email is not easy. more
For the last couple of years, the most common attack vector against the DNS system is the attack against the registrar. Either the attack is on the software itself using weaknesses in the code that could inject DNS changes into the TLD registry, or social engineering the registrar support systems and the attacker receives credentials that in turn allows the attacker to perform malicious changes in DNS. DNSSEC is the common security mechanism that protects the DNS protocol, but by using the registrar attack, any changes will result in a proper working DNS delegation. more
News flash: to help fight California's drought, Samsung is offering a $100,000 prize to the innovator who creates "the most effective use of IoT and ARTIK [Samsung's IoT platform] technology for reducing water consumption by individuals or municipalities." When the average reader of this news headline needs no explanation of what "IoT" means or what this contest is about, we know IoT, or the Internet of Things, is for real. There are already an estimated 25 billion connected devices around the world, according to expert estimates. more
