Lessons learned from Amazon/AWS outage

Phil Wainewright's seven lessons learned from the Amazon outage run the gamut from the benevolent "customers will forgive Amazon because they are Amazon" to a finger-wagging "Did I not warn you to read the label?" However, the most important lessons Phil warns us to learn underscore the concerns I expressed regarding cloud marketing a short while ago.

Cloud security is ultimately bounded by the same constraints as the enterprise - expertise, quality of processes and workflows, technology, monitoring, review, testing... - and also subject to the same if not expanded attack surface [1].

The irony we witnessed from the AWS outages is that putting all your faith and assets into a single cloud puts you into a single point of failure scenario.

Phil warns us not to take cloud provider assurances for granted., supplement your cloud provider's services with resilience/recovery measures of your own, and be prepared to pay more than the cloud invoice every month, because resiliency comes at a cost.

  • FTC's proposed Trade Regulation Rule on Impersonation of Government and Businesses is important for #infosec
    M3AAWG comments on the FTC's proposed rule Trade Regulation Rule on Impersonation of Government and Businesses is available. I was one of the contributors to the comment. In the comment, M3AAWG "suggests additional regulatory solutions and best practices to complement the goals of this rule, such as clarifying the scope of the rule to include the use of domain names in impersonation schemes and the use of technologies that enable impersonation" and the important role that Whois plays in investigating impersonation and fraud. Several reports that my Interisle colleagues and I published are cited in the comment, along with the...
  • Cybercrime Information Center reports sharp increases in phishing attacks, unique domains reported in August-October 2022 time period
    A recent ebb in domain names reported for phishing created some euphoria in the domain industry. With phishing activity, as with tides, ebbs are invariably followed by flows. In their August- October 2022 Quarterly Phishing Activity, the Cybercrime Information Center observed a 40% increase in phishing attacks and a nearly 20% increase in unique domain names reported for phishing.
  • Cybercrime Information Center's YouTube Channel
    My colleagues and I at Interisle have created a YouTube channel to complement the quarterly reporting and studies of cybercrime we host at the Cybercrime Information Center. Our goal is to share, in a few minutes, the findings and insights from our research in a format that's easily accessible and shareable, informative, and entertaining. The inaugural videos provide 2-5 minute summaries of our annual Phishing and Malware Landscape studies. We'll continue to produce videos of our annual studies. If you like what you see, leave us a comment.
  • Malware Landscape 2022: unabated malware growth, continued exploitation of IoT devices
    My colleagues at Interisle and I have published a study, Malware Landscape 2022: A Study of the Scope and Distribution of Malware. The study, which analyzed 2.5 million records of distinct malware events from May 2021 to April 2022 collected by the Cybercrime Information Center, explains what malware was most prevalent, where malware was served from, and what resources criminals used to pursue their attacks.
  • New TLDs are coming #Dangerclose.
    A Domain Name Wire post, Time to pay attention to the next round of new TLDs, begins with an ominous: They’re coming. Eventually. While not as dramatic or enduring as Arnold Schwarzenegger's "I'll be back", the reporter cites policy activity at ICANN as evidence that new TLDs are coming. Eventually. In a September 2019 post, and in response to the ICANN memorandum, Readiness to Support Future Rounds of New gTLDs, I asked, Has enough been done to study and rectify the concentration of security threats in the new TLD space? In that post, I quoted correspondence from ICANN's security advisory...
