Hello,

Just to be particularly annoying...

Forensic

1. relating to, connected with, or used in courts of law or public
discussion and debate.
2. adapted or suited to argumentation; argumentative.
3. applied to the process of collecting evidence for a legal case:
forensic accounting; forensic archaeology; forensic linguistics. [Latin
forens(is) of the forum + -IC]

--forensically, adverb

Just to reiterate. Forensic = court. Incident response is the correct
terminology that moist people are in all actuality coming to the belief

** "Moist"???  Are people perspiring *that* much?  ;P

** You are partially wrong in one term, and way off in the other term.  
** def: "forensics science" (ref: http://library.thinkquest.org/TQ0312020/whatisforens.htm)
** "Forensic science is any science used for the purposes of the law, and therefore provides
** impartial scientific evidence for use in the courts of law, and in a criminal
** investigation and trial. Forensic science is a multidisciplinary subject,
** drawing principally from chemistry and biology, but also from physics, geology,
** psychology, social science, etc."

** "Forensics" is often used to first *determine* through evidentuary methods
** (if possible, or obtainable), **IF** prosecution will be, or can be, possible, so it
** does not mean that a court hearing or prosecution trial is underway, or about to
** begin.  In most circumstances, forensic investigations are conducted BEFORE the trial.
** Lack of evidence, lack of chain of events leading to the crime (if any were committed),
** etc., are first determined by forensics specialists.

** Standard "forensics science" may also apply to IT or cyberforensics, but is treated as,
** or considered as, a subset to, general forensics.

** As defined: "Computer forensics, also called cyberforensics, is the application
** of computer investigation and analysis techniques to gather evidence suitable
** for presentation in a court of law. The goal of computer forensics is to perform
** a structured investigation while maintaining a documented chain of evidence to
** find out exactly what happened on a computer and who was responsible for it."
** (ref: http://searchcio.techtarget.com/gDefinition/0,294236,sid19_gci1007675,00.html)

** The definition for "incident response" is significantly different.  The term, by itself,
** is (purely) a reactionary response to an event, incident, or catastrophic scenario.
** This is (often times) reflective of an anticipated course of action that is taken
** immediately following such an event, or resulting from the outcome from such an event 
** (say a fire that destroys a building).  Disaster Recovery Planning and Business
** Continuity Planning are both forms of incident response.  BCP demonstrates what will be
** done to ensure that the business *continues* to operate as normally as possible after an
** incident.  DRP demonstrates how to handle the incident, who is to be involved, and what
** measures are needed to be taken to ensure "cleanup" of the disaster.

** Another definition: "Incident response is an organized approach to addressing and
** managing the aftermath of a security breach or attack (also known as an incident).
** The goal is to handle the situation in a way that limits damage and reduces
** recovery time and costs. An incident response plan includes a policy that defines,
** in specific terms, what constitutes an incident and provides a step-by-step process
** that should be followed when an incident occurs."
** (ref: http://searchcio.techtarget.com/gDefinition/0,294236,sid19_gci1121085_alpI,00.html)

** Incident Response Management (IRM) deals with both man-made disasters *and* natural
** disasters.  How is forensics tied to IRM based on a natural disaster?

** Think of it as like this: forensics science finds out who did it, and how they did it,
** and (perhaps) what was their motivation for doing it.  Incident response finds out
** what happened, how it happened, what caused it, and how is the business going to
** continue its course of operations.  Incident response might be responsive to an event
** caused by a single individual that is reflective of an forensics investigation; but may
** not necessarily always be so.  

** Though these terms may be inter-related, often times, they are usually not.

** One more thing to remember.  Incident response works at identifying FOUR (4) basic
** principles: PREPARATION, PROTECTION, RESPONSE, and RECOVERY.  I feel that a few more
** principles could be added, but for the most part, the industry feels that *primarily*
** these principles are a good start.  PREPARATION represents measures taken to ensure
** and minimize operational outages.  PROTECTION represents safeguarding activity
** against tampering and operational outages.  RESPONSE represents measures taken after
** an "incident" has occurred.  RECOVERY represents measures taken to RESTORE the
** enterprise to previous operational levels.  "RECOVERY" is sometimes referred to as
** "RESTORATION".

to be forensics.

Regards
Craig

Hello,
There is a confusion between forensic analysis and incident response.
Although these are related and in fact many people do both, they are not
the same. Incident response teams or personal are needed in many
organisations. Having a good investigative team makes life easier for a
forensic analyst.

They are however different roles. Oft the roles will overlap, but the
primary focus of forensics is obtaining and preserving evidence. This
may go against a corporations aims to have production systems running as
soon as possible.

I am not talking of LE at all. Rather I am stating insolvency support,
litigation support, etc.

Network security does not mean knowing where to look for logs. This is a
technical skill. Again a case where people get the more esoteric nature
of the role confused with the technical skills.

Very few people can investigate a hard drive in a manner that is
acceptable without challenger in court. This is the role of forensics.
General investigation is a role in incident response.

I am sure that this will garnish further comment - but I am a purist
when it comes to definitive terminology. Incident response and Forensics
are separate (though related disciplines). Most of the comments are
asking about the former though stating them as the latter.

Regards
Craig

I'm Sorry but I have to disagree with some of your statements while I
agree with some others.

1)  Many corporations in the US and around the world are hiring
EXPERIENCED forensic personnel.  I have worked as a consultant and for
private companies doing forensics for over 8 years now.  My start was
private.  I have never been "employed" by LE however, I have been hired
by govts/military for jobs.  You can start entry level Info Security and
get trained by one of their staff if they feel you are up to the
challenge.  I am training a few co-workers myself and am helping them on
the career path.

      Why corporate?  Espionage, sexual harrasment, porn,
assault/murder, hacking/incident response, identity theft, HIPAA/SOX,
resource abuse, etc. etc.  Believe me, there's plenty of work on the
corporate side - you don't have to go LE if you don't want to.  That's
just the tip of the iceberg.  You must assume that your cases will go to
court, especially if employees are terminated as a result of your
investigation.  Sometimes you work hand in hand with LE.  You can get
more than they can until you become their agent for internal
investigations.  But that's where you need ot know the law aspect.
Sometimes you need their assistance with items such as subpoenas, etc.
Also with the Calif law that is being adopted throughout the US, you
will be working with LE for disclousres.
2)  Network security is essential if you want to perform and
investigation.  How will you know where to look, what logs to obtain,
etc.  You must also know the law in the country, states and other
jurisdictions that the case involves (i.e subpoena in another
state/country).  Nothing personal but with the right tools, most anyone
can investigate a hard drive although they will most likely screw up the
acquisition, chain of custody and legal aspects thereby nullifying their
review.  Point being, it takes a lot of training and experience and if
you can't find your way around a network you;ve got no business doing an
investigation because you will only be looking at a small part of the
picture in many cases. 

3)  There is no "one" certification.  There are ones that are more
common, advisable etc. but there is no one stop shopping. 

4)  I agree with everything up to the "after incident response".  This
is because, IT people will most liekly trample your evidence.  Ideally
you should be preserving evidence while they correct a problem so it
should be in tandem.  Of course, many time it does occur after IT has
responded and corrected an issue.  Your company should make a decision
before hand wether their primary goal is recovery, forensics or both.
The answer will vary by system, issue, etc.
5)  There are classes you can take, some proprietary/some not.  There
are many groups you can join to learn if you are truly interested.  The
job can be boring and monotonous (i.e. Log reading and correlation) but
it's also a lot of fun.  It's a big game of hide and seek and I think
it's a blast.  It's never the same and you find out a lot about people.
6)  I totally agree with pretty much every other statement of Craig's.
It's work, it's integrity, it's honesty, a lot of good communication
skills, a knowledge of law, operating systems, networking, incident
response and recovery, network security, cryptography/steganography, and
the ability to think like criminals/abusers without actually being one.
You  must also remember that you can not speculate.  You present facts.
7)  Forensics is a science of processes.  It deals in facts.  There ARE
a lot of people and products who purport to be "forensics" but are not
and are well, we'll just say, "not able to present or be presentable" in
court for a number of reasons.

First, Computer Forensics is a separate discipline to Computer Security.
Next, incident response in business is not generally about forensics nor
does it have a lot to do with it.


Other than a low level knowledge of systems (and forget the tools based
- Encase training only - approach). A strong knowledge of law is
required.

Your job/role as a forensic services provider (of any type) is to
provide court support. This is it - full stop.

Your job is;
      1       Investigate. Document Preserve the "chain of evidence",
      2       Document everything. This is for and against. You have
to be impartial.
      3       Be prepared to sit in court and have your life,
experience and training picked apart.
      4       Answer the facts simply and succinctly, no more, no
less. What you are asked you answer. Your opinion only comes into this
when and IF your have been directly asked.

The role is slow and methodological. If you think accounting and being
an auditor is fun, than you may fit into the role.

Complete some courses in English grammar and report writing. This is an
essential skill. Spelling and punctuation can make or break your career
in this field.

Forensics has NOTHING to do with detection of an attack. It comes after
the attack. It comes after the initial incident response process.
Knowledge of incident response is needed to ensure the "chain of
evidence", but it is not generally part of your role as a forensic
analyst.

SANs GCFA is a good preliminary as is CCE. Neither will make you more
than an intern level by itself. You will be judged (at more than an
intern level) on how you handle cases. How you respond in court. Many
prospective employers will expect to view transcripts of cases you have
been involved with to see how you handle under cross.

You want to be top of the field. Many years. Much training. Calm
demeanour. Honesty. Integrity. This is the simple answer. There is a
great deal more as well. You need at least knowledge of the law (a
degree is not necessary, but does help. This is how experience as an
officer of the law aides). Absolutely NO knowledge of information
security is required (in contradiction to popular belief). It does help.

Familiarity of file-systems is crucial. Learn both Linux and Windows at
the least. Understand how to create a timeline. Know how to extract and
analyse slack space while maintaining evidential integrity. These are
some of the required skills (tip of the iceberg).

There are many people who profess to have computer forensic skills.
There are very few who really have these skills. There are even fewer
who can use their skills in court.

Craig

Koolk3,

I am also looking into this, I don't have much information but this is
what I've gathered:

- There seem to genarally be 2 facets of Forensics:
* Computer Forensics - pouring over someone's harddrive to gather and
document evidence.
* Network Forensics - Alot of what the folks on this list do on a day to
day basis, intrusion protection, detection and analysis.

You can persue one or the other but it sounds like you want a
combination of both.

- It has been suggested to me that if I was interested I should persue a
Law Enforcement career and go at it from that angle.  I have been a
Software developer for almost 20 years, in the US I'm too old for Law
Enforcement (35 yrs is the cutoff in my state) so that option is out for
me.

- Another suggestion was the FBI or CIA as a civilian professional or if
you meet the age/citizenship criteria an Agent.

- There are also private companies that do Computer Forensics and are
hired out by Lawyers or Law Enforcement that need the help when
computers are acquired in crimes.

I have taken a Computer Forensics class at the college level to get a
feel for that but unfortunately that isn't enough to get you in the door
(unless you get lucky).  I also get the feeling that without an IT
background you are out in the cold.

Another suggestion was to join one of the local chapters of the IACIS
(International Association of Computer Investigative Specialists).  I
think you would need to be invited in my an existing member and I'm not
sure if its only open to Law Enforcement folks checkout there website
(http://www.iacis.info/iacisv2/pages/home.php).  There are many
different groups, some are open to civilians and some are not.

Hope this helps a bit.  I look forward to comments from others to help
me in my quest also.

MH

Hi List,

I tried posting this before, didn't go through. So I am trying again.

I am interested in becoming a Forensics/Cyber Crime Investigator
preferably with any law enforcement agency in Canada. I will graduate
this April with a Bachelor in Computer Engineering. I have some
experince in Forensics and IT security from coop placements and wanted
to take this option as a career.

My questions are:

1) What kind of certification is the most demanding/respected among law
enforcement aganices in Canada/US?

2) If anyone on the list is with RCMP, OPP or any other law enforcement
agency here could you please give me any information on a possible
career path. Where do I start? Are these kind of jobs considered as a
civilian job?

3) Those in the USA: could you please tell me if I can have any prospect
there as a Canadian citizen. I would imagine you would need an US
citizen to work in the law enforcement agencies, but what about private
organizations?

4) Any information in building a career path in this field would be
helpful.

Thanks everyone.
