Operating Systems and Virtualisation Security Knowledge Area (Draft for Comment)
OPERATING SYSTEMS AND VIRTUALISATION SECURITY KNOWLEDGE AREA (DRAFT FOR COMMENT) AUTHOR: Herbert Bos – Vrije Universiteit Amsterdam EDITOR: Andrew Martin – Oxford University REVIEWERS: Chris Dalton – Hewlett Packard David Lie – University of Toronto Gernot Heiser – University of New South Wales Mathias Payer – École Polytechnique Fédérale de Lausanne © Crown Copyright, The National Cyber Security Centre 2019. Following wide community consultation with both academia and industry, 19 Knowledge Areas (KAs) have been identified to form the scope of the CyBOK (see diagram below). The Scope document provides an overview of these top-level KAs and the sub-topics that should be covered under each and can be found on the project website: https://www.cybok.org/. We are seeking comments within the scope of the individual KA; readers should note that important related subjects such as risk or human factors have their own knowledge areas. It should be noted that a fully-collated CyBOK document which includes issue 1.0 of all 19 Knowledge Areas is anticipated to be released by the end of July 2019. This will likely include updated page layout and formatting of the individual Knowledge Areas. Operating Systems and Virtualisation Security Herbert Bos Vrije Universiteit Amsterdam April 2019 INTRODUCTION In this knowledge area, we introduce the principles, primitives and practices for ensuring security at the operating system and hypervisor levels. We shall see that the challenges related to operating system security have evolved over the past few decades, even if the principles have stayed mostly the same. For instance, when few people had their own computers and most computing was done on multiuser (often mainframe-based) computer systems with limited connectivity, security was mostly focused on isolating users or classes of users from each other1. -
Internet Security
Internet Security Thompson Davis & Co. (TD & Co.) is committed to protecting the security and confidentiality of customer information. We use a combination of state-of-the-art technology and methods to help to protect the security of your online information. • Internet Communication Security Measures - Any sensitive personal information that you send through TD & Co. is held in a secured environment, protected by tools such as firewalls and/or database field encryption. Please do not send any sensitive or personal information over email. TD & Co. will not electronically send any personal financial information to you unless you request us to do so. • Protect Yourself from Fraudulent Web Sites - Personal information shared over the Internet can be used to commit fraud. One common method is for thieves to create a web site using a name that is similar to that of a reputable business, for instance by using a common misspelling of the company's name. The intent is to lure you into clicking onto the copycat web site and giving your personal information, including your account number and password. We caution you to make sure of whom you are dealing with over the Internet and to understand what will be done with your information. Always check that you have typed the correct web site address before entering personal information onto a site. • Personal Computer Security – Regardless of the security measures TD & Co. takes to protect your online financial information, if the computer or network you are using to access this data is not secure, you run the risk of your financial information being compromised. -
Malware Information
Malware Information Source: www.onguardonline.gov Malware Quick Facts Malware, short for "malicious software," includes viruses and spyware to steal personal information, send spam, and commit fraud. Criminals create appealing websites, desirable downloads, and compelling stories to lure you to links that will download malware – especially on computers that don't use adequate security software. But you can minimize the havoc that malware can wreak and reclaim your computer and electronic information. If you suspect malware is on your computer: • Stop shopping, banking, and other online activities that involve user names, passwords, or other sensitive information. • Confirm that your security software is active and current. At a minimum, your computer should have anti-virus and anti-spyware software, and a firewall. • Once your security software is up-to-date, run it to scan your computer for viruses and spyware, deleting anything the program identifies as a problem. • If you suspect your computer is still infected, you may want to run a second anti-virus or anti-spyware program – or call in professional help. • Once your computer is back up and running, think about how malware could have been downloaded to your machine, and what you could do to avoid it in the future. Malware is short for "malicious software;" it includes viruses – programs that copy themselves without your permission – and spyware, programs installed without your consent to monitor or control your computer activity. Criminals are hard at work thinking up creative ways to get malware on your computer. They create appealing web sites, desirable downloads, and compelling stories to lure you to links that will download malware, especially on computers that don't use adequate security software. -

Cyber Risks to Public Safety: Ransomware, September 2020
CYBER RISK TO PUBLIC SAFETY: RANSOMWARE RANSOMWARE IMPACTS ON PUBLIC SAFETY If you are experiencing a ransomware attack, please go directly to page 3 for incident reporting resources Ransomware is a type of malicious software that encrypts information stored on hard drives or network drives and disrupts access to compromised devices or networks. Ransomware applications threaten to erase, lock, or otherwise damage compromised drives and data unless payment is provided. Ransomware programs often elicit a sense of urgency (e.g., a short deadline for payment) to encourage affected organizations to pay. Ransomware applications may threaten to escalate demands (e.g., increase payment) if payment is not provided quickly. Even when payments are provided, malicious actors may steal sensitive information, default on agreements to restore access, or conduct follow-up cyberattacks. While ransomware typically aims to extort money from organizations, malicious actors may also target public safety agencies or critical infrastructure with the goal of disrupting emergency response capabilities.1, 2 Figure 1. Recent Ransomware Attack Statistics Ransomware can have a significant impact on public safety operations, including services provided by fire, emergency medical services, law enforcement, emergency communication centers/public safety answering points, and other public safety partners. Disruptions to public safety operations directly and negatively impact the health and safety of the communities they serve. For example, delays dispatching fire and emergency medical services may lead to increased loss of life and property damage. Malicious actors may target public safety agencies specifically to exploit these negative outcomes, creating a strong sense of urgency to accommodate perpetrator demands. Public safety agencies are highly encouraged to plan and prepare for a ransomware event to mitigate service disruptions, conduct effective response operations, and ensure rapid recovery. -

The Future of Anti-Spam: A Blueprint for New Internet Abuse Tools Garth Bruen, CEO Knujon.com LLC [email protected] Process and Document Map Abstract I. Introduction II. Failures and Limitations III. KnujOn Principles IV. Data Collection = Consumer Enfranchisement V. Sort, Categorize, Analyze VI. Redefining the Scope VII. Addressing the Support Structure VIII. Fixing Policy and Technology IX. Use the Law When Called For X. Brand Protection XI. The Daily Tally XII. Non-URL Successes XIII. Conclusion: What is Needed Next (Map of the Process and the Document) Abstract: It is this author’s contention that the efforts, technology, funding, and even critical thought in anti-spam development have been incorrectly focused on the email itself. In essence, the Internet security community has been “looking through the wrong end of the telescope.” Resources poured into larger and larger filtering engines and algorithms have failed to reduce the volume and flow of unsolicited email. In fact, spam volumes have generally increased since filtering was declared the de facto solution. The problem is not really about flaws in SMTP (simple mail transfer protocol), or email clients, or even email security in general. Nor is the problem solely attributed to botnets and malware. Garth Bruen and Dr. Robert Bruen have developed a solution that is based on mass abuse data collection, data analysis, policy enforcement, public reporting, and infrastructure enhancement. The ultimate key to solving the spam problem is about blocking transactions, stopping the flow of money to criminals who hire spammers to market their illicit products. Doing this through the existing, but enhanced, policy structure addresses the issue without exaggerated costs or reinventing the Internet.
