By: Pranshu Bajpai Introduction Computer Forensics is the methodical series...
Dear eForensics readers,
This time we decided to prepare a kind-off “introduction” to JumpStart series. The main focus of this is “What should you know beforehand to start a computer forensics investigation”. You will learn more about forensic education and carrier, secured network, incident response team and disaster recovery plans, about non-technical obstacles, comparison of some open-source tools and software vulnerabilities.

DIGITAL FORENSIC EDUCATION: WHAT TO DO IN ORDER TO GET WELL PREPARED
by Jose Ruiz
Digital forensics is a very broad line of work. It encompasses multiple areas regarding the recovery and analysis of data contained in digital devices. Many times this analysis goes hand in hand with the process of solving a computer crime. In such cases you need to prove or disprove a hypothesis either on civil, criminal or administrative forums. Also, digital forensics cover areas such as computer forensics, network forensics, mobile forensics, database forensics etc. Typically the process follow a similar structure that goes from seizing the evidence, acquire the image(s) and analyze them to finally produce a report or serve as an expert witness. You can correlate evidence to a crime or a suspect, authenticate documents, discover falsified data etc. For all of this you need a broad area of studies that not only requires forensic analysis methods. You also need to know about legal matters, response protocols, formal investigation procedures, writing quality reports and excellent verbal communication. This article will help the reader discover the various ways of gaining the right type of knowledge to succeed as a digital forensic analyst.

FISHING FOR CYBER FORENSICS TALENT OR HOW TO GET YOURSELF HOOKED INTO THE JOB
by Chris Walker, Agile Precis, LLC
Cyber talent is not as easy as you think to identify and hire. Not only do you have to go through the steps of hiring, but often, it is hard to tell what your candidate really knows and what they need to improve. There are two problems to solve then: how do you know if someone has the talent in cyber security to enter Cyber Forensics; the other is how do you, the potential candidate, enter into the field?
CHERISHING THE CHAIN OF CUSTODY
by David L. Biser
In any digital investigation an often overlooked but extremely important piece of the entire process is the chain of custody. The chain of custody is often the neglected child in the digital investigation and this needs to be corrected. Ensuring that a chain of custody is in place for each piece of evidence is vital to the successful conclusion of any case, whether legal or civil.
BUILDING SECURE NETWORK: AN INTRODUCTION

As the security paradigm shifted from “static” to “dynamic” defense, network companies need to adequate its security arsenal, not only about network security, but also end point protection, monitoring and backup policies.
THREAT INTELLIGENCE: A SYSTEM WITH FORESIGHT
by Deepayan Chanda
Threat landscape is changing, every day organizations are getting attacked, from the first ever known virus “Elk Cloner” in 1982, to the today’s most complex APT based attacks. How can we stay ahead of these advanced attacks, how can we monitor and detect these attacks well in advance? The answer to this is having a better and effective mechanism of threat information collection, analyzing related threats, identify and finally stopping them.
WHAT’S YOUR SECURITY WORTH? EXPLORING THE VULNERABILITIES MARKET
by Eric Vanderburg
Software vulnerabilities are nothing new. The cycle is rather predictable. Bug finders discover vulnerability and report it, receiving the kudos of the community and sometimes a small reward. Next, software companies fix the vulnerability through a patch or hotfix and users and companies are protected once the patch or hotfix is deployed in their environment. The situation has changed. Now companies and governments are willing to pay large sums of money for undisclosed vulnerabilities. Since these vulnerabilities are never disclosed, they are never fixed and the software is exploitable to those who purchased information on the vulnerability.
OH NO—NOW WHAT!?!? MANAGING NONTECHNICAL OBSTACLES TO THE SUCCESSFUL PERFORMANCE OF FORENSIC EXAMINATIONS IN LITIGATION
by Jeff Reed
Forensic examinations can be critical to the success or failure of a lawsuit. But there is an entire world of factors beyond a given set of technical skills that may affect the quality and outcome of an examination. Understanding, identifying and properly managing these factors is just as important as dealing appropriately with the data. Moreover, doing so will help keep the examinations moving in an orderly fashion with a minimum of disruption rather than one series of catastrophes after another.

USING PEACH TO DISCOVER VULNERABILITIES: FROM FUZZING TO EXPLOIT IN 5 STEPS
by Pedro Guillén Núñez, Josep Pi Rodríguez and Miguel Ángel de Castro
Nowadays, software vulnerabilities are an important risk for the companies. Reverse Engineering is a useful technique but it consumes much time and effort. However, Fuzzing gives good results and can be less expensive in terms of effort. Nowadays, the best approach is using both techniques. It is known that software companies include in their development cycle Fuzzingas the main technique in order to detect bugs.
