2.6 Auditing Linux/Unix Systems
Processing engine for security health checks Christofer Huynh, Jesper Gustafsson Department of Computer Science © Christofer Huynh, Jesper Gustafsson. LTH School of Engineering Lund University Box 882 SE-251 08 Helsingborg Sweden LTH Ingenjörshögskolan vid Campus Helsingborg Lunds universitet Box 882 251 08 Helsingborg Printed in Sweden. Lunds University Lund 2017 Abstract Computer security is still an often neglected field even though the IT industry is huge and still growing. Making sure that systems are secure is something that is very important but can take a lot of man hours. This thesis contains the research and documentation for an auditing tool created on behalf of a company that specialises in computer security, TrueSec. The audit tool uses the log files that are built from the scripts that TrueSec uses to runs various unix commands as a base, but it has been designed in such a way to allow the addition of other types of logs. The tool was designed with future development in mind. It uses configuration files that are seperated from the code itself to declare rules which the log files are checked against, allowing the tool to evolve with time by adding new rules. At the request of TrueSec a simple web service as a proof of concept for an online service with an authentication model with log in and user roles for uploading log files and storing the output from the audit tool was also developed. Keywords: audit tool, computer security, security audit, analysis engine, security health check 3 Sammanfattning Datasäkerhet är fotfarande ofta ett misskött fält även fast IT- sektorn är stor och fortfarande växer. -
Lynis Enterprise on the Other Hand Has Much More Possibilities to Display Data, Including Extended Reports in Several Formats
Lynis Lynis Installation and Usage • Introduction • Installation • Using Lynis • Basics • Commands, Options, and Arguments • Suggestions and Warnings • Behind the scenes • Profiles • HostIDs Introduction Lynis is an open source security tool. It helps with auditing systems running UNIX-alike systems (Linux, macOS, BSD), and providing guidance for system hardening and compliance testing. This document contains the basics to use the software. Installation The installation of Lynis is explained in the Get Started guide. Using Lynis Basics By running 'lynis' the program is started and will provide the basic parameters available. If you manually extracted Lynis (or used Git), then use './lynis' to start the program from the local directory. The most common command to start Lynis is using audit system command. This still start the security scan. To run Lynis you should meet one requirement: have write access to /tmp (temporary files) Commands, Options, and Arguments Introduction The behavior of programs can influenced with commands, arguments, and options. These terms are often mixed up, so we start with a quick introduction. Commands tell the program what to do. An option tells the program how to do it. If an argument is used, it tell on what it applies. Arguments usually follow an option, like a filename, or a target. Example $ ./lynis audit system --quick --auditor "The Auditor" In this example we tell Lynis to audit (command), with the target system (argument). By using the --quick (option), we tell it not to wait. We used --auditor (option) and defined it as "The Auditor" (argument). Lynis Commands The Lynis tool requires a minimum amount of parameters to run. -

This thesis covers the positioning of penetration testing within IT risk management frameworks and the relationship between IT risk management and penetration testing. We would like to express our thanks to Dr. René Matthijsse RE, our supervisor at the Vrije Universiteit, for his support and criticism. Additionally, we would like to express our thanks to Mr. Michiel van Veen MSc RE and ir. Peter Kornelisse for their support during the course of the project. We would not have come this far without them. Furthermore, we would like to thank the participants to our case study interviews for their time and availability to express their opinion and share their experience on this subject. Last but not least we would like to thank our families for their support and their patience with us during our study. Without them we definitely would not have made it.

Pre-engagement Critical: Scope NDA Reporting Never do anything you do not have an agreement for (get out of Jail-Free-Card) What are the client’s goals – why do they want a pentest What data are important to the client/ what matters most to them? ** Do they know what a pentest is, what is required to do one properly? ** Do they understand a pentest could crash a system? Who do you contact / what times of the day can you do the work? 2. Information Gathering - What has the client told you ** think social engineering - What is available publically * LinkedIn; job adverts; social sites - What would a hacker find to allow them to attack the system - http://www.netcraft.com/ - whois <url> - nslookup / dig / host -t ns url - Can you get dns records?
