  • Cybersecurity in a Digital Era.Pdf
    Digital McKinsey and Global Risk Practice Cybersecurity in a Digital Era June 2020 Introduction Even before the advent of a global pandemic, executive teams faced a challenging and dynamic environ- ment as they sought to protect their institutions from cyberattack, without degrading their ability to innovate and extract value from technology investments. CISOs and their partners in business and IT functions have had to think through how to protect increasingly valuable digital assets, how to assess threats related to an increasingly fraught geopolitical environment, how to meet increasingly stringent customer and regulatory expectations and how to navigate disruptions to existing cybersecurity models as companies adopt agile development and cloud computing. We believe there are five areas for CIOs, CISOs, CROs and other business leaders to address in particular: 1. Get a strategy in place that will activate the organization. Even more than in the past cybersecurity is a business issue – and cybersecurity effectiveness means action not only from the CISO organiza- tion, but also from application development, infrastructure, product development, customer care, finance, human resources, procurement and risk. A successful cybersecurity strategy supports the business, highlights the actions required from across the enterprise – and perhaps most importantly captures the imagination of the executive in how it can manage risk and also enable business innovation. 2. Create granular, analytic risk management capabilities. There will always be more vulnerabilities to address and more protections you can consider than you will have capacity to implement. Even companies with large and increasing cybersecurity budgets face constraints in how much change the organization can absorb.

  • The Six Dumbest Ideas in Computer Security Marcus J Ranum
    The Six Dumbest Ideas in Computer Security Marcus J Ranum http://www.ranum.com/security/computer_security/editorials/dumb/ There's lots of innovation going on in security - we're inundated with a steady stream of new stuff and it all sounds like it works just great. Every couple of months I'm invited to a new computer security conference, or I'm asked to write a foreword for a new computer security book. And, thanks to the fact that it's a topic of public concern and a "safe issue" for politicians, we can expect a flood of computer security-related legislation from lawmakers. So: computer security is definitely still a "hot topic." But why are we spending all this time and money and still having problems? Let me introduce you to the six dumbest ideas in computer security. What are they? They're the anti-good ideas. They're the braindamage that makes your $100,000 ASIC-based turbo-stateful packet-mulching firewall transparent to hackers. Where do anti-good ideas come from? They come from misguided attempts to do the impossible - which is another way of saying "trying to ignore reality." Frequently those misguided attempts are sincere efforts by well- meaning people or companies who just don't fully understand the situation, but other times it's just a bunch of savvy entrepreneurs with a well-marketed piece of junk they're selling to make a fast buck. In either case, these dumb ideas are the fundamental reason(s) why all that money you spend on information security is going to be wasted, unless you somehow manage to avoid them.

  • 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.

  • From Insider Threats to Business Processes That Are Secure-By-Design∗ Dieter Gollmann† Hamburg University of Technology Hamburg, Germany [email protected]
    From Insider Threats to Business Processes that are Secure-by-Design∗ Dieter Gollmanny Hamburg University of Technology Hamburg, Germany [email protected] Abstract We argue that insider threat is a placeholder term that accompanies the transition from securing IT infrastructures to securing the socio-technical systems made possible by these IT infrastructures. The term insider in its literal interpretation loses meaning in a context where there are no stable perime- ters one can refer to. Business practices such as outsourcing, employing temporary contractors, and the very use of IT, have removed security perimeters in the search for short-term efficiency gains, which may result in mid-term losses due to increased vulnerabilities. We conclude that securing socio-technical systems calls for the design of organisational (business) processes that remain viable once inside information about their implementation becomes available to potential attackers rather than for the deployment of secure IT infrastructures. Keywords: Insider threats, business process, IT security 1 Introduction Security is a fashion industry. Ever so often a new buzzword gets adopted that dresses up issues that had been around for a long time. Insider threats are an example in case. This term has entered discourses about security in recent years, reaching also into the research community, see e. g. [1, 2, 3]. However, the observation that threats to an organization can emanate from insiders is old news in IT security. Back in the early 1990s depending on whom you asked, 70%, 80%, or 90% of security incidents in commercial entities were due to insiders, where counts may have referred to the number of incidents or to the size of the damage.

  • Secure by Design White Paper
    WHITE PAPER Secure by Design: UniPrint Infinity’s Multi-Layer Approach to Cloud Printing Security © Process Fusion The moving of IT infrastructure up to the cloud usually results in companies being obliged to give up monitoring of their IT, with this being delegated to third-party vendors. Naturally, the thought of losing security controls over sensitive corporate data leads to decision-makers raising concerns surrounding the security of their files in the cloud! UniPrint Infinity’s innovative product empowers users with end-to-end cloud printing security. With its multi- layer approach, UniPrint Infinity secures your cloud printing architecture from all angles. This whitepaper will discuss the four key security features offered by UniPrint’s cloud printing solution. One Virtual Print Queue In today’s IT-driven enterprise world, user-friendliness, cost-savings, and enhanced security protection are paramount to the success of any organization! Enterprises must ensure that all their IT systems and related workflows incorporate all three of these features. Printing, over the course of time, has developed a reputation of being a source of pain for both enterprise employees and administrators. With complicated user interfaces, poor user experience, issues with driver misconfigurations, printer mapping errors, print data security concerns, and network maintenance costs, enterprise printing has been a nightmare for everyone involved. The advent of cloud printing has helped to solve some of these issues, with organizations moving their infrastructure to the cloud, effectively lowering costs and eliminating printer mapping and related misconfiguration issues. UniPrint Infinity’s Virtual Print Queue (VPQ) adds a whole new level of security to cloud printing! The implementation of UniPrint’s VPQ to your cloud printing environment means users printing from cloud environments such as Microsoft Azure send their print jobs to a single virtual print queue when they print from their workstations or mobile devices.

James Tanner has been approved August 10, 2009 APPROVED: VICTORIA SCHAUFUSS, PhD (ABD), Chair GREG MILES, PhD, CISSP, CISA, CISM, IAM, IEM, Independent Reviewer SHELLEY KEATING, MSIT, IEM, IAM, CCNA, MCSE+l, Network+, A+, CTT+, Independent Reviewer AL KELLY, MSIS, MCSA, MCSE 2000m /2003, IEM, IAM, Network+, A+, MCT, Independent Reviewer ACCEPTED AND SIGNED: __________________________________________ VICTORIA SCHAUFUSS, PhD (ABD) Abstract Securing a computer from unwanted intrusion requires astute planning and effort to effectively minimize the security invasions computers are plagued with today. While all of the efforts to secure a computer are needed, it seems that the underlying issue of what is being secured has been overlooked. The operating system is at the core of the security issue. Many applications and devices have been put into place to add layers of protection to an already weak operating system. Security did not used to be such a prominent issue because computers were not connected 24/7, they used dialup and did not experience the effects from connecting to multiple computers. Today computers connect to high speed Internet and seem useless without access to email, chat, Internet, and videos. This interconnectedness of computers has allowed the security of many computers to be compromised because they have not been programmatically secured. The core component of computer security might best be done through security layers protecting the operating system.

  • 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.

  • Apple at Work Platform Security
    Apple at Work Platform Security Secure by design. At Apple, we care deeply about security—both for the user and for protecting corporate data. We’ve built advanced security into our products from the ground up, making them secure by design. And we’ve done this in a way that’s in balance with a great user experience, giving users the freedom to work the way they want. Only Apple can provide this comprehensive approach to security, because we create products with integrated hardware, software, and services. Hardware security Secure software requires a foundation of security built into hardware. That’s why Apple devices—running iOS, iPadOS, macOS, tvOS, or watchOS—have security capabilities designed into silicon. These include custom CPU capabilities that power system security features and silicon dedicated to security functions. The most critical component is the Secure Enclave coprocessor in modern iOS, iPadOS, watchOS, and tvOS devices and in all Mac computers with the Apple T2 Security Chip. The Secure Enclave provides the foundation for encrypting data at rest, secure boot in macOS, and biometrics. All modern iPhone, iPad, and Mac computers with a T2 chip include a dedicated AES hardware engine to power line-speed encryption as files are written or read. This ensures that Data Protection and FileVault protect users’ files without exposing long-lived encryption keys to the CPU or operating system. Secure boot of Apple devices ensures that the lowest levels of software aren’t tampered with and that only trusted operating system software from Apple loads at startup. In iOS and iPadOS devices, security begins in immutable code called the Boot ROM, which is laid down during chip fabrication and known as the hardware root of trust.
