  • Updating code can mean fewer security headaches

    Organizations with high rates of code deployments spend half as much time fixing security issues as organizations without such frequent code updates, according to a newly released study.

    In its latest annual state-of-the-developer report, Devops software provider Puppet found that by better integrating security objectives into daily work, teams in "high-performing organizations" build more secure systems. The report, which surveyed 4,600 technical professionals worldwide, defines high IT performers as offering on-demand, multiple code deploys per day, with lead times for changes of less than one hour. Puppet has been publishing its annual report for five years.

  • Over half of world's top domains weak against email spoofing

    Over half of the world's most popular online services have misconfigured servers which could place users at risk from spoof emails, researchers have warned.

    According to Swedish cybersecurity firm Detectify, poor authentication processes and configuration settings in servers belonging to hundreds of major online domains are could put users at risk of legitimate-looking phishing campaigns and fraudulent emails.

Security

Today, June 24, 2016, renowned Linux kernel developer Greg Kroah-Hartman has announced the general availability of the third maintenance release for the Linux 4.6 kernel series.

Linux kernel 4.6.3 is here two weeks after the release of the second maintenance update in the series, Linux kernel 4.6.2, to change a total of 88 files, with 1302 insertions and 967 deletions. Unfortunately, very few GNU/Linux distributions have adopted the Linux 4.6 series, despite the fact that Greg Kroah-Hartman urged everyone to move to this most advanced kernel branch as soon as possible from Linux 4.5, which reached end of life.

  • Mozilla Awards $385,000 to Open Source Projects as part of MOSS “Mission Partners” Program

    For many years people with visual impairments and the legally blind have paid a steep price to access the Web on Windows-based computers. The market-leading software for screen readers costs well over $1,000. The high price is a considerable obstacle to keeping the Web open and accessible to all. The NVDA Project has developed an open source screen reader that is free to download and to use, and which works well with Firefox. NVDA aligns with one of the Mozilla Manifesto’s principles: “The Internet is a global public resource that must remain open and accessible.”

  • Want To Be A Cool Security Guru?

    Well it will take some work, security is not like what they show on TV. You don’t need green on black text, special goggles or an unlimited enhance function. Instead, it requires sitting down and understanding the history of the field, what it means to be “secure” and what limitations or assumptions you can work under. This summer I have decided to start my journey on the vast field of cryptography and am doing an online course at Stanford University that provides an introduction to cryptography. It is appropriately named “Cryptography I” and is the first part of a two part course, the second part being offered later in the Fall. Both are taught by a really awesome professor Dan Boneh who I find explains the material very well. I decided I would like to make some posts about what I have learned in this course as I go through the material so that I can share my knowledge and get a chance to write it down somewhere for later reference.

  • Decentralized Security

    If you're a fan of the cryptocurrency projects, you've heard of something called Ethereum. It's similar to bitcoin, but is a seperate coin. It's been in the news lately due to an attack on the currency. Nobody is sure how this story will end at this point, there are a few possible options, none are good. This got me thinking about the future of security, there are some parallels when you compare traditional currency to crypto currency as well as where we see security heading (stick with me here).

    The current way currency works is there is some central organization that is responsible for minting and controlling the currency, usually a country. There are banks, exchanges, loans, interest, physical money, and countless other ways the currency interacts with society. We will compare this to how IT security has mostly worked in the past. You had one large organization responsible for everything. If something went wrong, you could rely on the owner to take control and make things better. There are some instances where this isn't true, but in general it holds.

    Now if we look at cryptocurrency, there isn't really a single group or person in charge. That's the whole point though. The idea is to have nobody in charge so the currency can be used with some level of anonymity. You don't have to rely on some sort of central organization to give the currency legitimacy, the system itself has legitimacy built in.

  • Making a Case for Security Analytics

    Being a victim of a data breach no longer results in a slap on the wrist. Instead it can lead to costly fines, job loss, physical damage and an organization's massive loss of reputation. Case in point: Target. Following its high-profile breach in late 2013, Target suffered large losses in market valuation and paid more than $100 million in damages.

  • Web Application Defender's Field Report: Account Takeover Campaigns Spotlight

    ATO attacks (also known as credential stuffing) use previously breached username and password pairs to automate login attempts. This data may have been previously released on public dumpsites such as Pastebin or directly obtained by attackers through web application attacks such as SQLi. The goal of the attacks is to identify valid login credential data that can then be sold to gain fraudulent access to user accounts. ATO may be considered a subset of brute force attacks, however it is an increasing threat because it is harder to identify such attacks through traditional individual account authentication errors. The Akamai Threat Research Team analyzed web login transactions for one week across our customer base to identify ATO attack campaigns.

  • Google's security princess talks cybersecurity

    Her talk was even-keeled, informative, and included strong FOSS messaging about everyone's vested interest in internet security and privacy.

BusyBotNet is a Fork of Busybox with Security Tools

OSS
Security

Busybox provides a lightweight version of common command line utilities normally found on “big” Linux into a single binary, in order to bring them to embedded systems with limited memory and storage. As more and more embedded systems are now connected to the Internet, or as they are called nowadays the Internet of Things nodes, adding security tools, such as cryptographic utilities, could prove useful for administrators of such system, and so BusyBotNet project wsa born out of a fork of Busybox.
