Modern Password Security for System Designers What to Consider When Building a Password-Based Authentication System
Modern password security for system designers What to consider when building a password-based authentication system By Ian Maddox and Kyle Moschetto, Google Cloud Solutions Architects This whitepaper describes and models modern password guidance and recommendations for the designers and engineers who create secure online applications. A related whitepaper, Password security for users, offers guidance for end users. This whitepaper covers the wide range of options to consider when building a password-based authentication system. It also establishes a set of user-focused recommendations for password policies and storage, including the balance of password strength and usability. The technology world has been trying to improve on the password since the early days of computing. Shared-knowledge authentication is problematic because information can fall into the wrong hands or be forgotten. The problem is magnified by systems that don't support real-world secure use cases and by the frequent decision of users to take shortcuts. According to a 2019 Yubico/Ponemon study, 69 percent of respondents admit to sharing passwords with their colleagues to access accounts. More than half of respondents (51 percent) reuse an average of five passwords across their business and personal accounts. Furthermore, two-factor authentication is not widely used, even though it adds protection beyond a username and password. Of the respondents, 67 percent don’t use any form of two-factor authentication in their personal life, and 55 percent don’t use it at work. Password systems often allow, or even encourage, users to use insecure passwords. Systems that allow only single-factor credentials and that implement ineffective security policies add to the problem. -

Security Now! Transcript of Episode #800 Page 1 of 27 Transcript of Episode #800 SolarBlizzard Description: This week we open the New Year taking a longer look at fewer topics since the bad guys were apparently enjoying their New Year holiday, too. So we look at an interesting kludge that's been forced upon Chrome by ill-mannered antiviral scanners. We need to warn all enterprise users of Zyxel network border security products of another recently discovered built-in backdoor. We look at the rise in IoT compromise swatting attacks and a series of new flaws and vulnerabilities in the PHP Zend and Yii frameworks. We have a quick bit of miscellany to share, then I want to explain a lot about the value of trimming SSDs and newer SMR drives. And we'll conclude by catching up with what will hopefully be the last news, for a while at least, of the disastrous SolarWinds breach and intrusions.

Steve Gibson is here with a defunct football; a very bad AV security practice that Chrome has had to do something maybe even worse to fix. We'll talk about the built-in password access in 100,000 Zyxel firewalls, VPN gateways, and access point controllers; an update on SpinRite 6.1; and a whole lot more. Security Now! is coming up next. -

Zero-Knowledge User Authentication: an Old Idea Whose Time Has Come
Zero-Knowledge User Authentication: An Old Idea Whose Time Has Come Laurent Chuat, Sarah Plocher, and Adrian Perrig ETH Zurich Abstract User authentication can rely on various factors (e.g., a pass- word, a cryptographic key, and/or biometric data) but should not re- veal any secret information held by the user. This seemingly paradoxical feat can be achieved through zero-knowledge proofs. Unfortunately, naive password-based approaches still prevail on the web. Multi-factor authen- tication schemes address some of the weaknesses of the traditional login process, but generally have deployability issues or degrade usability even further as they assume users do not possess adequate hardware. This as- sumption no longer holds: smartphones with biometric sensors, cameras, short-range communication capabilities, and unlimited data plans have become ubiquitous. In this paper, we show that, assuming the user has such a device, both security and usability can be drastically improved using an augmented password-authenticated key agreement (PAKE) pro- tocol and message authentication codes. 1 Introduction User authentication still typically involves transmitting a plaintext password to the web server, which is problematic for many reasons. First, an attacker could obtain the user’s password using malware, a keystroke logger, phishing, or a man-in-the-middle attack. Second, the user might be using the same password on different websites, allowing a malicious server operator to impersonate the user. Third, if the website’s database is breached, although passwords may be protected by a hash function, a brute-force attack could reveal low-entropy pass- words. Fourth, as password-reuse and low-entropy passwords are problematic, users are constantly advised to pick new, long, complicated passwords. -

Podcast Industry Audience Rankings July 2016
PODCAST INDUSTRY AUDIENCE RANKINGS JULY 2016 2 INTRODUCTION With the growing popularity of podcasts, more and more brands and agencies are exploring the medium in search of opportunities that make the most sense for their brands. And publishers are making important content decisions about ways to expand or better serve their audiences across multiple shows. What is the most accurate measure of podcast audience size? An obvious place for advertisers to begin exploring podcast advertising is with understanding the relative audience sizes of podcast publishers and of podcasts individually. Podtrac has provided the leading measurement service for podcasts since 2005. In 2016, Podtrac introduced “Monthly Unique Audience” for the podcast industry. It's the same metric used for planning other types of digital media, and for the first time it's available for podcasts from Podtrac. Monthly Unique Audience from Podtrac is available: ● By podcast publisher across all of the podcast shows and episodes they produce ● By show for all of the podcast episodes they produce ● By global and U.S. audience counts “Monthly Unique Audience” is an important metric in digital media because it enables advertisers and publishers to consider monthly audience reach in addition to potential impressions served. And as with other media, the monthly unique audience metrics from Podtrac are consistent across publishers and shows whether the episodes post daily, twice a week, weekly, etc. Which podcasts are audiences listening to most? Podtrac produces a monthly Ranking Report showing the top publishers in the industry by US audience. Podtrac is in a unique position to produce this report, because of its podcast measurement technology and its 10+ years of measurement relationships with substantially all of the top publishers in the industry. -
