Systematization of Vulnerability Discovery Knowledge: Review
Systematization of Vulnerability Discovery Knowledge Review Protocol Nuthan Munaiah and Andrew Meneely Department of Software Engineering Rochester Institute of Technology Rochester, NY 14623 {nm6061,axmvse}@rit.edu February 12, 2019 1 Introduction As more aspects of our daily lives depend on technology, the software that supports this technology must be secure. We, as users, almost subconsciously assume the software we use to always be available to serve our requests while preserving the confidentiality and integrity of our information. Unfortunately, incidents involving catastrophic software vulnerabilities such as Heartbleed (in OpenSSL), Stagefright (in Android), and EternalBlue (in Windows) have made abundantly clear that software, like other engineered creations, is prone to mistakes. Over the years, Software Engineering, as a discipline, has recognized the potential for engineers to make mistakes and has incorporated processes to prevent such mistakes from becoming exploitable vulnerabilities. Developers leverage a plethora of processes, techniques, and tools such as threat modeling, static and dynamic analyses, unit/integration/fuzz/penetration testing, and code reviews to engineer secure software. These practices, while effective at identifying vulnerabilities in software, are limited in their ability to describe the engineering failures that may have led to the introduction of vulnerabilities. Fortunately, as researchers propose empirically-validated metrics to characterize historical vulnerabilities, the factors that may have led to the introduction of vulnerabilities emerge. Developers must be made aware of these factors to help them proactively consider security implications of the code that they contribute. In other words, we want developers to think like an attacker (i.e. inculcate an attacker mindset) to proactively discover vulnerabilities. -

Compromised Connections
COMPROMISED CONNECTIONS OVERCOMING PRIVACY CHALLENGES OF THE MOBILE INTERNET The Universal Declaration of Human Rights, the International Covenant on Civil and Political Rights, and many other international and regional treaties recognize privacy as a fundamental human right. Privacy A WORLD OF INFORMATION underpins key values such as freedom of expression, freedom of association, and freedom of speech, IN YOUR MOBILE PHONE and it is one of the most important, nuanced and complex fundamental rights of contemporary age. For those of us who care deeply about privacy, safety and security, not only for ourselves but also for our development partners and their missions, we need to think of mobile phones as primary computers As mobile phones have transformed from clunky handheld calling devices to nifty touch-screen rather than just calling devices. We need to keep in mind that, as the storage, functionality, and smartphones loaded with apps and supported by cloud access, the networks these phones rely on capability of mobiles increase, so do the risks to users. have become ubiquitous, ferrying vast amounts of data across invisible spectrums and reaching the Can we address these hidden costs to our digital connections? Fortunately, yes! We recommend: most remote corners of the world. • Adopting device, data, network and application safety measures From a technical point-of-view, today’s phones are actually more like compact mobile computers. They are packed with digital intelligence and capable of processing many of the tasks previously confined -

How Solarwinds Patch Manager Can Help the NHS Avoid Ransomware Attacks
WHITE PAPER How SolarWinds Patch Manager Can Help the NHS Avoid Ransomware Attacks page 1 How Solarwinds Patch Manager Can Help the NHS Avoid Ransomware Attacks In May of 2017, the WannaCry virus took a dramatic toll on the U.K.’s National Health Service (NHS)—the largest single-payer healthcare system in the world. According to a report released by the National Audit Office (NAO)*, the attack is believed to have infected machines at 81 health trusts—which accounts for nearly one-third of NHS trusts in the U.K. In addition, according to the report, 19,500 medical appointments were cancelled, computers at 600 general practices were locked, and five hospitals had to divert ambulances to other medical facilities. WannaCry works by infecting an organisation’s infrastructure and encrypting its data, then requiring a ransom payment to unencrypt the data and have it be accessible once again. “The WannaCry cyberattack … was a relatively unsophisticated attack and could have been prevented by the NHS following basic IT security best practice,” stated Amyas Morse, head of the National Audit Office, in conjunction with issuing the report. “There are more sophisticated cyberthreats out there than WannaCry, so the NHS needs to get their act together to ensure they are better protected against future attacks.” According to the report, the vulnerability was able to penetrate the system because of a lack of patching. Patches are provided by vendors to resolve known vulnerabilities. THE VALUE OF PATCH MANAGEMENT Patch management is a basic IT security function. The value in performing regular patch management is undeniable, particularly as IT vendors make it easier and easier to implement.
