    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.

    Secure by Design, Secure by Default: Requirements and Guidance

    Biometrics and Surveillance Camera Commissioner Secure by Design, Secure by Default Video Surveillance Products Introduction This guidance is for any organisation manufacturing Video Surveillance Systems (VSS), or manufacturing or assembling components intended to be utilised as part of a VSS. It is intended to layout the Biometrics and Surveillance Camera Commissioners (BSCC) minimum requirements to ensure such systems are designed and manufactured in a manner that assures they are Secure by Design. It also contains certain component requirements that will ensure a configuration that is Secure by Default when the component is shipped, thereby making it more likely that the system will be installed and left in a secure state. This guidance forms part of a wider suite of documentation being developed as part of the SCC Strategy, in support of the SCC Code of Practice. Background and Context The nature of the Internet means that connected devices can be subjected to a cyber attack from anywhere in the world. Widespread attacks on connected products is a current and real threat, and a number of highly publicised attacks have already occurred. The Mirai malware targeted devices such as internet-enabled cameras (IP cameras). Mirai was successful because it exploited the use of common default credentials (such as a username and password being set by the manufacturer as ‘admin’) and poor security configuration of devices. Ultimately, this facilitated attacks on a range of commercial and social media services and included an outage of streaming services such as Netflix. An evolution of Mirai, called Reaper, has also been discovered. Reaper used publicly and easily available exploits that remained unfixed (patched) and highlighted the problem around non patching of known security vulnerabilities, allowing attackers to utilise them to cause harm.

    Why cybersecurity is crucial for today’s physical access control www.nedapsecurity.com Your protector needs protecting Many modern physical access control systems are IP-based, powered by smart software and able to process large quantities of data. This provides more functionality, flexibility, scalability and opportunities for integration. But it also means they’re part of your IT network, so it’s essential they’re protected and upgraded – just like your other IT systems. How could your physical access control system be compromised by cybercrime? Cybercrime is becoming more sophisticated every day and comes in various guises. It could, for example, involve retrieving or manipulating data sent between devices to reveal who has access where and when. Or it might involve access card data being collected and then copied or cloned. Taking a step further, cybercriminals may steal someone’s credentials to enable them to log into your access control system’s software. Once they’re logged in, they can enable unwanted access to all kinds of doors and locations. And, by gaining access to your database, they can manipulate or even remove events that show what they or others did, for example. What can you do to protect your physical access control system? Nobody can say that something is 100% cybersecure, but prevention is definitely better than cure. Key measures are to cybersecure your access control hardware and software. And also your data storage and the way data is accessed and transferred – not just within one building, but nationally and internationally. Many different components tend to be connected to IP-based physical access control systems, so it’s important every one of them is protected against cyberattacks – from cards to cameras, readers, databases, controllers and more.
  • The Rocky Relationship Between Safety and Security

    The Rocky Relationship Between Safety and Security

    The rocky relationship between safety and security Best practices for avoiding common cause failure and preventing cyber security attacks in Safety Systems Abstract: An industry practice reflected in the international safety standards (i.e. IEC 61508) is the need for independence among the multiple protection layers on an industrial site “…the EUC control system shall be independent from the E/E/PE safety-related systems and other risk reduction measures…” however even the 1st generation of digital Safety Systems (Electronic/Programmable Electronic Systems) had communication ports with support for open protocols (i.e. Modbus RTU) in order to provide diagnostics and other information relevant for the operation of process (EUC). Users have connected (interfaced) safety systems to BPCS since mid 1980s and aimed to develop tighter connectivity at least since 1995. These efforts were based on proprietary protocols until the adoption of open network protocols and Windows on industrial control systems increased the connectivity to business systems and at the same (at least in theory) exposed them to the same issues (virus, cyber attacks, etc). This paper will discuss the methods used to ensure that the integration between the safety system and the BPCS DO NOT compromise Functional Independence and define best practices to secure an industrial system and in particular safety systems in this integrated environment. 1 1 Why do we care about safety (and security)? A report published by Aberdeen Research in November 2011 (Ismail, 2011) indicates that despite the difference in motivations, Best-in-Class companies must establish a formalized risk management strategy and ingrain safety as part of the culture through executive leadership.
  • Building Secure and Reliable Systems

    Building Secure and Reliable Systems

    Building Secure & Reliable Systems Best Practices for Designing, Implementing and Maintaining Systems Compliments of Heather Adkins, Betsy Beyer, Paul Blankinship, Piotr Lewandowski, Ana Oprea & Adam Stubblefi eld Praise for Building Secure and Reliable Systems It is very hard to get practical advice on how to build and operate trustworthy infrastructure at the scale of billions of users. This book is the first to really capture the knowledge of some of the best security and reliability teams in the world, and while very few companies will need to operate at Google’s scale many engineers and operators can benefit from some of the hard-earned lessons on securing wide-flung distributed systems. This book is full of useful insights from cover to cover, and each example and anecdote is heavy with authenticity and the wisdom that comes from experimenting, failing and measuring real outcomes at scale. It is a must for anybody looking to build their systems the correct way from day one. —Alex Stamos, Director of the Stanford Internet Observatory and former CISO of Facebook and Yahoo This book is a rare treat for industry veterans and novices alike: instead of teaching information security as a discipline of its own, the authors offer hard-wrought and richly illustrated advice for building software and operations that actually stood the test of time. In doing so, they make a compelling case for reliability, usability, and security going hand-in-hand as the entirely inseparable underpinnings of good system design. —Michał Zalewski, VP of Security Engineering at Snap, Inc. and author of The Tangled Web and Silence on the Wire This is the “real world” that researchers talk about in their papers.

Today we're going to talk about better security. Steve Gibson: Well, yeah. Actually, this is one of those episodes where so much happened in the last week in security news that, I mean, we just - there's a whole bunch of really interesting stuff to talk about. And in the past when we've done that we've just said, okay, we're not going to have any major topic because too much happened.
