  • Static Vulnerability Analysis of Docker Images
    DEGREE PROJECT FOR MASTER OF SCIENCE IN ENGINEERING COMPUTER SECURITY Static Vulnerability Analysis of Docker Images Michael Falk | Oscar Henriksson Blekinge Institute of Technology, Karlskrona, Sweden, 2017 Supervisor: Emiliano Casalicchio, Department of Computer Science and Engineering, BTH Abstract Docker is a popular tool for virtualization that allows for fast and easy deployment of applications and has been growing increasingly popular among companies. Docker also include a large library of images from the repository Docker Hub which mainly is user created and uncontrolled. This leads to low frequency of updates which results in vulnerabilities in the images. In this thesis we are developing a tool for determining what vulnerabilities that exists inside Docker images with a Linux distribution. This is done by using our own tool for downloading and retrieving the necessary data from the images and then utilizing Outpost24’s scanner for finding vulnerabilities in Linux packages. With the help of this tool we also publish statistics of vulnerabilities from the top downloaded images of Docker Hub. The result is a tool that can successfully scan a Docker image for vulnerabilities in certain Linux distributions. From a survey over the top 1000 Docker images it has also been shown that the amount of vulnerabilities have increased in comparison to earlier surveys of Docker images. Keywords: Docker, Containerization, Vulnerability analysis, Vulnerability scanning i Sammanfattning Docker är ett populärt verktyg för virtualisering som används för att snabbt och enkelt sätta upp applikationer och har vuxit sig populärt bland företag. Docker inkluderar även ett stort bibliotek av images från datakatalogen Docker Hub vilket huvudsakligen består av användarskapat och okontrollerat innehåll.

  • Why Open Source Software / Free Software (OSS/FS, FLOSS, Or FOSS)? Look at the Numbers!
    Translations available: Czech | French | Japanese | Spanish Why Open Source Software / Free Software (OSS/FS, FLOSS, or FOSS)? Look at the Numbers! David A. Wheeler http://www.dwheeler.com/contactme.html Revised as of July 18, 2015 This paper (and its supporting database) provides quantitative data that, in many cases, using open source software / free software (abbreviated as OSS/FS, FLOSS, or FOSS) is a reasonable or even superior approach to using their proprietary competition according to various measures. This paper’s goal is to show that you should consider using OSS/FS when acquiring software. This paper examines popularity, reliability, performance, scalability, security, and total cost of ownership. It also has sections on non-quantitative issues, unnecessary fears, OSS/FS on the desktop, usage reports, governments and OSS/FS, other sites providing related information, and ends with some conclusions. An appendix gives more background information about OSS/FS. You can view this paper at http://www.dwheeler.com/oss_fs_why.html (HTML format). A short presentation (briefing) based on this paper is also available. Palm PDA users may wish to use Plucker to view this longer report. Old archived copies and a list of changes are also available. 1. Introduction Open Source Software / Free Software (aka OSS/FS), also described as Free/Libre and Open Source Software (FLOSS), has risen to great prominence. Briefly, FLOSS programs are programs whose licenses give users the freedom to run the program for any purpose, to study and modify the program, and to redistribute copies of either the original or modified program (without having to pay royalties to previous developers).

  • Installing and Configuring Linux Guest Operating Systems Vmware® Infrastructure 3
    Technical Note Installing and Configuring Linux Guest Operating Systems VMware® Infrastructure 3 Datacenters today have a mix of Windows and Linux workloads. IDC estimates in 2008 that 68 percent of all physical servers shipped are Windows‐based, compared to 23 percent that are Linux‐based. However, the proliferation of Linux environments is steadily increasing. From 2006 to 2011, IDC forecasts the compounded annual growth rate (CAGR) of physical server units running Linux at 28.1 percent, with Windows trailing at 25.0 percent. As more datacenters are virtualized with VMware Infrastructure 3, it makes sense that these virtualized environments are also trending towards increased use of Linux. The CAGR of virtual server units running Linux is forecasted by IDC at 44.1 percent, with Windows behind at 39.0 percent. Linux operating systems now host applications from databases to Web servers to application servers, much as their Windows counterparts do. Linux guest operating systems are here, and VMware is dedicated to supporting them. This technical note describes installing, configuring, updating, and administering Linux guest operating systems in virtual machines running on VMware Infrastructure 3 version 3.5 (specifically VMware VirtualCenter 2.5 Update 2 and VMware ESX 3.5 Update 2). In addition, this note includes a collection of useful tips and tricks in fine‐tuning your Linux virtual machines, which may or may not apply to all your Linux usage scenarios. Although the recommendations in this paper apply to most Linux distributions, they are tailored specifically to Red Hat Enterprise Linux 5. IDC observed in 2007 that of all paid Linux subscriptions, Red Hat Enterprise Linux came in at 62.1 percent and Novell SUSE Linux Enterprise Server placed second at 29 percent.
