Signature: Date: Academic Year 2013/2014 Copyright c 2013/2014 by Joaquin Moreno Garijo Abstract Mac OS X Forensics by Joaquin Moreno Garijo Master of Science in Information Security Royal Holloway, University of London 2013/2014 During the past few years, the number of incidents related with Mac OS X environ- ment have increased, especially those related to malware. Due to this new tendency, incident response teams and computer forensics investigators require new tools, proce- dures and documentation to understand how to properly handle the incidents over this platform. However, the research undertaken till now is not enough to deal with these new threats. For this reason, the research community has started to work on volatile evi- dences, live system evidences and malware reversing approaches. However, the research done over persistent evidences has almost been non-existent, in particular the evidences created by Mac OS X itself. -
Software Process Recovery: Recovered Unified Process Views
Evidence-based Software Process Recovery by Abram Hindle A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in Computer Science Waterloo, Ontario, Canada, 2010 c Abram Hindle 2010 I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Developing a large software system involves many complicated, varied, and inter- dependent tasks, and these tasks are typically implemented using a combination of defined processes, semi-automated tools, and ad hoc practices. Stakeholders in the development process | including software developers, managers, and customers | often want to be able to track the actual practices being employed within a project. For example, a customer may wish to be sure that the process is ISO 9000 compliant, a manager may wish to track the amount of testing that has been done in the current iteration, and a developer may wish to determine who has recently been working on a subsystem that has had several major bugs appear in it. However, extracting the software development processes from an existing project is ex- pensive if one must rely upon manual inspection of artifacts and interviews of developers and their managers. Previously, researchers have suggested the live observation and in- strumentation of a project to allow for more measurement, but this is costly, invasive, and also requires a live running project. -
Tehnologii Internet
UNIVERSITATEA DIN BACĂU F ACULTATEA DE I NGINERIE POPA SORIN EUGEN TEHNOLOGII INTERNET note de curs şi aplicaţii pentru studenţii Facultăţii de Inginerie 2007 Cuvânt înainte, Volumul "Tehnologii Internet" se adresează studenţilor de la specializarea Tehnologia informaţiei anul III şi cuprinde atât cursul cât şi lucrările de laborator pentru disciplina cu acelaşi nume. Cartea este structurată pe două părţi, prima, de noţiuni teoretice, conţine 6 capitole care încearcă să acopere, cât mai succint, o parte din întinsul domeniul al tehnologiilor utilizate pentru a crea, întreţine, administra, securiza şi, nu în ultimul rând, a utiliza Internetul. Partea a doua conţine 12 lucrări de laborator în care studenţii vor experimenta mare parte din ceea ce este prezentat în curs. Primul capitol, "Conceptele Internetului" face o descriere succintă a noţiunii de internet, cu descrierea modelului de referinţă OSI care stă la baza dezvoltării reţelelor de calculatoare, implicit a internetului. Apoi continuă cu clasificarea tehnologiilor Internet: hardware, software,d e comunicaţii şi Dataware. Al doilea capitol, intitulat "Servicii Internet sub FreeBSD" prezintă ore scurt istoria şi dezvoltarea sistemului FreeBSD, care este un sistem de operare open source, bazat de UNIX, şi la ora actială, considerat ca fiind cel mai sigur, stabil şi rapid. Tot aici se prezintă şi configurarea unui server multifuncţional: mail, ftp, web şi baze de date. Capitolul al treilea tratează tehnologiile Internet din punctul de vedere al sistemului de operare Windows, prezentând procedurile şi modul de configurare a acestuia ca server cu aceleaşi roluri ca şi cel sub FreeBSD. Capitolul patru, denumit generic "Protocoale şi servicii" face o prezentare şi descriere succintă a principalelor protocoale utilizate în Internet, şi anume: DNS, SSH, telnet, http. -
