Automating Security Checks
Mag. iur. Dr. techn. Michael Sonntag Automating security checks Institute for Information Processing and Microprocessor Technology (FIM) Johannes Kepler University Linz, Austria E-Mail: [email protected] http://www.fim.uni-linz.ac.at/staff/sonntag.htm © Michael Sonntag 2010 Agenda Why automatization? What can be automated? Example: Skipfish How reliable are these tools? Practical examples of searching for vulnerabilities: Information collection with NMap Password cracking (John the Ripper, Ophcrack) Exploit scanning with Nessus Michael Sonntag Automating security checks 2 Why automatization? Ensuring security is not that hard for a single system You know it in detail When something is discovered, it is implemented and tested But: Many sites with many configuration options? Do you know them all? » Are they identical everywhere (versions!)? Do you have time to change everything accordingly? » Or do you depend on automatic updates/roll-out? Are you sure you did not miss one option somewhere? » Testing the same thing several times is tedious Solution: Automatic testing whether a problem exists Professionals write tests You just apply them » No need to know exactly how the attack works! Regular re-testing is possible Ad-hoc & patchy testing Systematic & comprehensive Michael Sonntag Automating security checks 3 Overlap with monitoring Some overlap with system monitoring exists Failures are just a “different kind” of attack Some problems may occur accidentally or intentionally » Example: Blacklisting of mail -

Analysis of Password Cracking Methods & Applications John A. Chester The University of Akron Abstract -- This project examines the nature of password cracking and modern applications. Several applications for different platforms are studied. Different methods of cracking are explained, including dictionary attack, brute force, and rainbow tables. Password cracking across different mediums is examined. Hashing and how it affects password cracking is discussed. An implementation of two hash-based password cracking algorithms is developed, along with experimental results of their efficiency. I. Introduction Password cracking is the process of either guessing or recovering a password from stored locations or from a data transmission system [1]. -

Accesso Alle Macchine Virtuali in Lab Vela
Accesso alle Macchine Virtuali in Lab In tutti i Lab del camous esiste la possibilita' di usare: 1. Una macchina virtuale Linux Light Ubuntu 20.04.03, che sfrutta il disco locale del PC ed espone un solo utente: studente con password studente. Percio' tutti gli studenti che accedono ad un certo PC ed usano quella macchina virtuale hanno la stessa home directory e scrivono sugli stessi file che rimangono solo su quel PC. L'utente PUO' usare i diritti di amministratore di sistema mediante il comando sudo. 2. Una macchina virtuale Linux Light Ubuntu 20.04.03 personalizzata per ciascuno studente e la cui immagine e' salvata su un server di storage remoto. Quando un utente autenticato ([email protected]) fa partire questa macchina Virtuale LUbuntu, viene caricata dallo storage centrale un immagine del disco esclusivamente per quell'utente specifico. I file modificati dall'utente vengono salvati nella sua immagine sullo storage centrale. L'immagine per quell'utente viene utilizzata anche se l'utente usa un PC diverso. L'utente nella VM è studente con password studente ed HA i diritti di amministratore di sistema mediante il comando sudo. Entrambe le macchine virtuali usano, per ora, l'hypervisor vmware. • All'inizio useremo la macchina virtuale LUbuntu che salva i file sul disco locale, per poterla usare qualora accadesse un fault delle macchine virtuali personalizzate. • Dalla prossima lezione useremo la macchina virtuale LUbuntu che salva le immagini personalizzate in un server remoto. Avviare VM LUBUNTU in Locale (1) Se la macchina fisica è spenta occorre accenderla. Fatto il boot di windows occorre loggarsi sulla macchina fisica Windows usando la propria account istituzionale [email protected] Nel desktop Windows, aprire il File esplorer ed andare nella cartella C:\VM\LUbuntu Nella directory vedete un file LUbuntu.vmx Probabilmente l'estensione vmx non è visibile e ci sono molti file con lo stesso nome LUbuntu. -
Chapter 5 Results
CHAPTER 5 RESULTS 5.1 Results This chapter will discuss the results of the testing and comparison of the password cracking tools used. This chapter can be summarized as follows: • Research Data and Result Analysis (Locally) • Research Data and Result Analysis (Remotely) • Research Data and Result Analysis (Alphabets only) • Research Data and Result Analysis (Alphabets and a special character) 5.2 Research Data and Result Analysis (Locally) In Figure 16, Ophcrack was used to crack the local users' password with different combinations of password, alphabets, alphanumeric, alphanumeric special characters, english and non-english words. In Figure 17, Ophcrack was used to crack the same password, but excluding the 3 password that were not cracked in the previous attempt. In Figure 18, Cain was used to crack the local users' password. 35 36 Figure 16 - Ophcrack cracked 7 of 10 passwords Figure 17 - Ophcrack cracked 7 of 7 passwords 37 Figure 18 - Cain cracked 5 of 10 passwords 5.3 Research Data and Result Analysis (Remotely) First, the author scans the network for active IP address with NMAP (Figure 19). He used the command of "nmap -O 192.168.1.1-254" to scan the network, it would scan each IP address for active computer. The command -O enabled operating system detection. From the result of the scanning, there were few ports in the state of open and the services that were using those ports, 135/TCP, 139/TCP, 445/TCP and 1984/TCP. Another important detail was the OS details; it showed that the computer was running under Microsoft Windows XP Professional SP2 or Windows Server 2003. -

Password Attacks and Generation Strategies
PASSWORD ATTACKS AND GENERATION STRATEGIES Predrag Tasevski Tartu University, Faculty of Mathematics and Computer Sciences, major: Master of Science in Cyber Security May 21, 2011 Table of contents Introduction Methods Ad-hoc models Brute force Rainbow tables Examples and tools Comparison of input dictionary list Test Conclusion INTRODUCTION Password is a secret word or string of characters that is used for authentication in order to prove identity or gain access to a resource[Gill(1997)]. I Usage of password cracking tools I Methods and approaches guessing the passwords I Examples of leaks and generating password dictionaries I Comparison of already cracked passwords from available password dictionaries and I Test METHODS Password cracking is a method of guessing the attack. Types of password cracking methods[Vines(2007)]: I Dictionary I Hybrid I Brute force Ad-hoc models Dictionary attacks - colander rules Example Capitalization the rst letter, adding three digits to the end, changing the letter `a' to `@' etc. Hybrid it adds simple numbers or symbols to the password attempt. Brute force Brute force are fraction of the total words that are made by users creating their passwords. Brute force attacks methods: I Pure brute force [Group(2010)] I Letter frequency analysis attack [Stitson(2003)] I Markov models [Shmatikov Arvind(2005)] I Targeted brute force attacks [WEIR(2010b)] Rainbow tables (1) Rainbow tables are using the reduction functions to create multiple parallel chains within a single "rainbow" table. I Increases the probability of a correct crack for a given table size, the use of multiple reduction functions also greatly increases the speed of look-ups [JeXChen(2011)]. -
