Computer forensics is the process of examining computer systems, storage devices, and digital evidence to recover data for legal cases. It involves collecting, preserving, analyzing and presenting computer-related evidence without altering it. Computer evidence can be useful in criminal, civil and employment cases. Computer forensics experts follow strict methodologies to carefully handle systems and extract potential evidence while maintaining data integrity and chain of custody. Their goal is to discover all relevant files, including deleted files, and analyze artifacts to understand attempts to hide, delete or encrypt information.

Computer forensics is the “who, what, when, and how” of electronic evidence. Typically narrow in scope, it attempts to reconstruct events, focusing on the computer-based conduct of an individual or group of individuals. The types of cases involving computer forensics are numerous and varied – from the personal (i.e. locating hidden assets in a messy divorce case), to the political (i.e. investigating alleged misuse of government computers for political gain), to the dramatic (i.e. “What was your client’s former
employee downloading from the Internet before he was fired
and brought suit for wrongful termination?”).
Internet Evidence Finder (IEF) is a digital forensics solution that can search a hard drive, live RAM captures, or files for Internet-related evidence. IEF was designed with digital forensics examiners/investigators in mind. IEF is also used by security professionals, prosecutors, incident response teams, and cyber security personnel.Find out why IEF is trusted by many of the world’s most demanding military departments and government agencies.

Maintaining The Digital Chain of Custody By John Patzakis .docxsmile790243
Maintaining The Digital Chain of Custody
By John Patzakis
[email protected]
Employing proper computer forensic processes is the foundation of computer
investigations. Even the best corporate policies for incident response and computer data
preservation can mistakenly allow the mishandling of potentially key computer evidence.
Once compromised, either during the collection or analysis process, the evidentiary
integrity of the data is lost.
Computer investigators must follow four basic steps in order to correctly maintain
a digital chain of custody. These include:
• Physically control the scene, or if conducting a remote network investigation, log
all access and connectivity through an integrated and secure reporting function
• Create a binary, forensic duplication of original data in a non-invasive manner
• Create a digital fingerprint (hash) that continually verifies data authenticity
• Log all investigation details in a thorough report generated by an integrated
computer forensics software application
The Problem of Improper Computer Evidence Handling
Maintaining the integrity of computer evidence during an internal investigation or
incident response is important, especially when computer evidence may be presented in
court. This is true whether human resource personnel suspect that an employee’s
violation of company policies may warrant termination, if IT staff are responding to a
network intrusion, or outside consultants suspect criminal activity that may need to be
reported to authorities. However, the ability to maintain and precisely document digital
contents, including its exact location on the subject media should stand as the
cornerstone of any computer investigation. By not taking steps to preserve the digital
chain of custody, a company is leading itself into an investigation that is compromised
from the beginning.
Such a lax investigation also can make it difficult to later map out the exact
location of electronic evidence on a drive, or to prove who manipulated or created data,
as it is no longer clear if it was the suspect or the investigator who was the last to access
it. In fact, this is the reason that worldwide agencies regulating financial institutions have
mandated incident response plans.
Recent policies, standards, and court decisions strongly establish a compelling
obligation for all types of businesses to preserve electronic data that may be relevant to
a legal matter, audit, etc. On the U.S. legislative front, the Sarbanes-Oxley Act, which
passed in response to the Enron/Arthur Anderson debacle, imposes severe penalties for
the destruction of records, including electronic data. The act expressly prohibits the
destroying records in “contemplation” of an investigation or proceeding. Securities
Exchange Commission rules require retention for six years of all business-related email
and Internet communications sent and received by brokers, dealers and exchange
members ...

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

01 Computer Forensics Fundamentals - Notes
1. COMPUTER FORENSICS UNIT I – PART I 1
WHAT IS COMPUTER FORENSICS?
Computer forensics is the process of methodically examining computer media (hard disks, diskettes,
tapes, etc.) for evidence. In other words, computer forensics is the collection, preservation, analysis,
and presentation of computer-related evidence.
Computer forensics also referred to as computer forensic analysis, electronic discovery, electronic
evidence discovery, digital discovery, data recovery, data discovery, computer analysis, and
computer examination.
Computer evidence can be useful in criminal cases, civil disputes, and human resources/
employment proceedings.
USE OF COMPUTER FORENSICS IN LAW ENFORCEMENT
Computer forensics assists in Law Enforcement. This can include:
Recovering deleted files such as documents, graphics, and photos.
Searching unallocated space on the hard drive, places where an abundance of data often resides.
Tracing artifacts, those tidbits of data left behind by the operating system. Our experts know how to
find these artifacts and, more importantly, they know how to evaluate the value of the information
they find.
Processing hidden files — files that are not visible or accessible to the user — that contain past
usage information. Often, this process requires reconstructing and analyzing the date codes for each
file and determining when each file was created, last modified, last accessed and when deleted.
Running a string-search for e-mail, when no e-mail client is obvious.
COMPUTER FORENSICS ASSISTANCE TO HUMAN RESOURCES/EMPLOYMENT PROCEEDINGS ***
Computers can contain evidence in many types of human resources proceedings, including sexual
harassment suits, allegations of discrimination, and wrongful termination claims.
Evidence can be found in electronic mail systems, on network servers, and on individual employee’s
computers.

EMPLOYER SAFEGUARD PROGRAM
Employers must safeguard critical business information. An unfortunate concern today is the possibility
that data could be damaged, destroyed, or misappropriated by a discontented individual.
Before an individual is informed of their termination, a computer forensic specialist should come on-site
and create an exact duplicate of the data on the individual’s computer. In this way, should the employee
choose to do anything to that data before leaving, the employer is protected.
Damaged or deleted data can be re-placed, and evidence can be recovered to show what occurred. This
method can also be used to bolster an employer’s case by showing the removal of proprietary
information or to protect the employer from false charges made by the employee.
You should be equipped to find and interpret the clues that have been left behind. This includes
situations where files have been deleted, disks have been reformatted, or other steps have been taken
to conceal or destroy the evidence. For example, did you know?
What Web sites have been visited?
What files have been downloaded?
When files were last accessed?
Of attempts to conceal or destroy evidence?
Of attempts to fabricate evidence?
That the electronic copy of a document can contain text that was removed from the final printed
version?
That some fax machines can contain exact duplicates of the last several hundred pages received?
That faxes sent or received via computer may remain on the computer indefinitely?
That email is rapidly becoming the communications medium of choice for businesses?
That people tend to write things in email that they would never consider writing in a memorandum
or letter?
That email has been used successfully in criminal cases as well as in civil litigation?
That email is often backed up on tapes that are generally kept for months or years?
That many people keep their financial records, including investments, on computers?

COMPUTER FORENSICS SERVICES *****
Computer forensics professionals should be able to successfully perform complex evidence recovery
procedures with the skill and expertise that lends credibility to your case.
For example, they should be able to perform the following services:
1. DATA SEIZURE
Following federal guidelines, computer forensics experts should act as the representative, using
their knowledge of data storage technologies to track down evidence.
The experts should also be able to assist officials during the equipment seizure process.
2. DATA DUPLICATION/PRESERVATION
When one party must seize data from another, two concerns must be addressed:
o the data must not be altered in any way
o the seizure must not put an undue burden on the responding party
The computer forensics experts should acknowledge both of these concerns by making an exact
duplicate of the needed data.
When experts works on the duplicate data, the integrity of the original is maintained.
3. DATA RECOVERY
Using proprietary tools, your computer forensics experts should be able to safely recover and
analyze otherwise inaccessible evidence.
The ability to recover lost evidence is made possible by the expert’s advanced understanding of
storage technologies.
4. DOCUMENT SEARCHES
Computer forensics experts should also be able to search over 200,000 electronic documents in
seconds rather than hours.
The speed and efficiency of these searches make the discovery process less complicated and less
intrusive to all parties involved.
4. COMPUTER FORENSICS UNIT I – PART I 4
5. MEDIA CONVERSION
Computer forensics experts should extract the relevant data from old and un-readable devices,
convert it into readable formats, and place it onto new storage media for analysis.
6. EXPERT WITNESS SERVICES
Computer forensics experts should be able to explain complex technical processes in an easy-to-
understand fashion.
This should help judges and juries comprehend how computer evidence is found, what it consists of,
and how it is relevant to a specific situation.
7. COMPUTER EVIDENCE SERVICE OPTIONS
Computer forensics experts should offer various levels of service, each designed to suit your individual
investigative needs. For example, they should be able to offer the following services:
Standard service: Computer forensics experts should be able to work on your case during nor-mal
business hours until your critical electronic evidence is found.
On-site service: Computer forensics experts should be able to travel to your location to per-form
complete computer evidence services. While on-site, the experts should quickly be able to produce
exact duplicates of the data storage media in question.
Emergency service: Your computer forensics experts should be able to give your case the highest
priority in their laboratories. They should be able to work on it without interruption until your
evidence objectives are met.
Priority service: Dedicated computer forensics experts should be able to work on your case during
normal business hours (8:00 A.M. to 5:00 P.M., Monday through Friday) until the evidence is found.
Priority service typically cuts your turnaround time in half.
Weekend service: Computer forensics experts should be able to work from 8:00 A.M. to 5:00 P.M.,
Saturday and Sunday, to locate the needed electronic evidence and will continue 14 Computer
Forensics, Second Edition working on your case until your evidence objectives are met.
5. COMPUTER FORENSICS UNIT I – PART I 5
8. OTHER MISCELLANEOUS SERVICES
Computer forensics experts should also be able to provide extended services. These services include:

BENEFITS OF PROFESSIONAL FORENSIC METHODOLOGY ****
A knowledgeable computer forensics professional should ensure that a subject computer system is
carefully handled to ensure that:
1. No possible evidence is damaged, destroyed, or otherwise compromised by the procedures used to
investigate the computer.
2. No possible computer virus is introduced to a subject computer during the analysis process.
3. Extracted and possibly relevant evidence is properly handled and protected from later mechanical or
electromagnetic damage.
4. A continuing chain of custody is established and maintained.
5. Business operations are affected for a limited amount of time, if at all.
6. Any client-attorney information that is inadvertently acquired during a forensic exploration is
ethically and legally respected and not divulged.
6. COMPUTER FORENSICS UNIT I – PART I 6
STEPS TAKEN BY COMPUTER FORENSICS SPECIALISTS *****
The computer forensics specialist should take several careful steps to identify and attempt to retrieve
possible evidence that may exist on a subject’s computer system. For example, the following steps
should be taken:
1. Protect the subject computer system during the forensic examination from any possible alteration,
damage, data corruption, or virus introduction.
2. Discover all files on the subject system. This includes existing normal files, deleted yet remaining
files, hidden files, password-protected files, and encrypted files.
3. Recover all of discovered deleted files.
4. Reveal the contents of hidden files as well as temporary or swap files used by both the application
programs and the operating system.
5. Access the contents of protected or encrypted files.
6. Analyze all possibly relevant data found in special areas of a disk. This includes but is not limited to
what is called unallocated space on a disk, as well as slack space in a file (the remnant area at the
end of a file in the last assigned disk cluster, that is unused by current file data, but once again, may
be a possible site for previously created and relevant evidence).
7. Print out an overall analysis of the subject computer system, as well as a listing of all possibly
relevant files and discovered file data.
8. Provide an opinion of the system layout; the file structures discovered; any discovered data and
authorship information; any attempts to hide, delete, protect, and encrypt information; and
anything else that has been discovered and appears to be relevant to the overall computer system
examination.
9. Provide expert consultation and/or testimony, as required.
