C is to low level
I'm in danger of contradicting myself, after previously pointing out that x86 machine code is a high-level language, but this article claiming C is a not a low level language is bunk. C certainly has some problems, but it's still the closest language to assembly. This is obvious by the fact it's still the fastest compiled language. What we see is a typical academic out of touch with the real world.The author makes the (wrong) observation that we've been stuck emulating the PDP-11 for the past 40 years. C was written for the PDP-11, and since then CPUs have been designed to make C run faster. The author imagines a different world, such as where CPU designers instead target something like LISP as their preferred language, or Erlang. This misunderstands the state of the market. CPUs do indeed supports lots of different abstractions, and C has evolved to accommodate this.
The author criticizes things like "out-of-order" execution which has lead to the Spectre sidechannel vulnerabilities. Out-of-order execution is necessary to make C run faster. The author claims instead that those resources should be spent on having more slower CPUs, with more threads. This sacrifices single-threaded performance in exchange Continue reading

Short Take: Security as a Tradeoff
We often treat security as an absolute, “that which must be done, and done perfectly, or is of no value at all.” It’s time to take this myth head on, and think about how we should really think about security.

SafeKeeper: protecting web passwords using trusted execution environments
SafeKeeper: protecting web passwords using trusted execution environments Krawiecka et al., WWW’18
(If you don’t have ACM Digital Library access, the paper can be accessed either by following the link above directly from The Morning Paper blog site, or from the WWW 2018 proceedings page).
Today’s paper is all about password management for password protected web sites / applications. Even if we assume that passwords are salted and hashed in accordance with best practice (NIST’s June 2017 digital identity guidelines now mandate the use of keyed one-way functions such as CMAC), an adversary that can obtain a copy of the back-end database containing the per-user salts and the hash values can still mount brute force guessing attacks against individual passwords.
SafeKeeper goes a lot further in its protection of passwords. What really stands out is the threat model. SafeKeeper keeps end user passwords safe even when we assume that an adversary has unrestricted access to the password database. Not only that, the adversary is able to modify the content sent to the user from the web site (including active content such as client-side scripts). And not only that! The adversary is also able to read all Continue reading
SD-WAN: Managed or DIY?
In this eBrief from SDxCentral, we compare the pros and cons of using a managed SD-WAN service vs. the DIY model. In addition, we talk to one enterprise about its SD-WAN experience.
masscan, macOS, and firewall
One of the more useful features of masscan is the "--banners" check, which connects to the TCP port, sends some request, and gets a basic response back. However, since masscan has it's own TCP stack, it'll interfere with the operating system's TCP stack if they are sharing the same IPv4 address. The operating system will reply with a RST packet before the TCP connection can be established.The way to fix this is to use the built-in packet-filtering firewall to block those packets in the operating-system TCP/IP stack. The masscan program still sees everything before the packet-filter, but the operating system can't see anything after the packet-filter.
Note that we are talking about the "packet-filter" firewall feature here. Remember that macOS, like most operating systems these days, has two separate firewalls: an application firewall and a packet-filter firewall. The application firewall is the one you see in System Settings labeled "Firewall", and it controls things based upon the application's identity rather than by which ports it uses. This is normally "on" by default. The packet-filter is normally "off" by default and is of little use to normal users.
Also note that macOS changed packet-filters around version 10.10. Continue reading

Short Take – Security As A Tradeoff
In this episode Russ White talks about how security absolutism is actually detrimental to securing important data and systems, and how shifting our view of security to a balance of tradeoffs would be a much better approach.

RIPE 76 Sees Strong Focus on Routing Security
The RIPE 76 meeting is happening this week in Marseille, France, held at the fantastic location of the Palais du Pharo overlooking Marseille’s Old Port. And it’s also another record attendance with over 850 people registered.
The first couple of days have primarily been devoted to plenary sessions, and there’s been a big focus on routing security. Erik Bais (A2B Internet) kicked off the discussion with a presentation on ‘Why are we still seeing DDoS traffic?‘, which highlighted that DDoS attacks are still originating from the same networks. Looking at the list of the worst offenders, there’s even one amongst the regular RIPE attendees, and he called for networks to clean up their acts. This was also a good opportunity to highlight the MANRS initiative, which of course includes measures to mitigate amplification attacks, and encourages networks to make good routing practices the norm.
Alexander Azimov (Qrator Labs) reinforced this message by outlining the current problems with BGP, including the ongoing route leaks and hijacks affecting the Internet. There are currently only moral obligations to not use other providers’ address space or to support anti-spoofing policies, yet major providers (including Tier 1 providers) continue to both originate Continue reading

Why I’m Joining Cloudflare
I love working as a Chief Security Officer because every day centers around building something that makes people safer. Back in 2002, as I considered leaving my role as a cybercrime federal prosecutor to work in tech on e-commerce trust and safety, a mentor told me, “You have two rewarding but very different paths: you can prosecute one bad actor at a time, or you can try to build solutions that take away many bad actors' ability to do harm at all.” And while each is rewarding in its own way, my best days are those where I get to see harm prevented—at Internet scale.
In 2016, while traveling the United States to conduct hearings on the condition of Internet security as a member of President Obama's cyber commission, my co-commissioners noticed I had fallen into a pattern of asking the same question of every panelist: “Who is responsible for building a safer online environment where small businesses can set up shop without fear?” We heard many answers that all led to the same “not a through street” conclusion: Most law enforcement agencies extend their jurisdiction online, but there are no digital equivalents to the Department of Continue reading
