Gaius Julius Caesar (13 July 100 BC – 15 March 44 BC) was a Roman general and statesman. He played a critical role in the gradual transformation of the Roman Republic into the Roman Empire.
In 60 BC, Caesar entered into a political alliance with Crassus and Pompey that was to dominate Roman politics for several years. Their attempts to amass power for themselves through populist tactics were opposed within the Roman Senate by the conservative elite, among them Cato the Younger with the frequent support of Cicero. Caesar's conquest of Gaul extended Rome's territory to the North Sea, and in 55 BC he conducted the first Roman invasion of Britain. These achievements granted him unmatched military power and threatened to eclipse Pompey's standing. The balance of power was further upset by the death of Crassus in 53 BC. Political realignments in Rome finally led to a stand-off between Caesar and Pompey, the latter having taken up the cause of the Senate. Ordered by the senate to stand trial in Rome for various charges, Caesar marched from Gaul to Italy with his legions, crossing the Rubicon in 49 BC. This sparked a civil war from which he emerged as the unrivaled leader of the Roman world.
After assuming control of government, he began extensive reforms of Roman society and government. He centralised the bureaucracy of the Republic and was eventually proclaimed "dictator in perpetuity". A group of senators, led by Marcus Junius Brutus, assassinated the dictator on the Ides of March (15 March) 44 BC, hoping to restore the constitutional government of the Republic. However, the result was a series of civil wars, which ultimately led to the establishment of the permanent Roman Empire by Caesar's adopted heir Octavius (later known as Augustus). Much of Caesar's life is known from his own accounts of his military campaigns, and other contemporary sources, mainly the letters and speeches of Cicero and the historical writings of Sallust. The later biographies of Caesar by Suetonius and Plutarch are also major sources.
Information security

Information Security Components: or qualities, i.e., Confidentiality,Integrity and Availability (CIA).
Information Systems are decomposed in three main portions,
hardware,
software and communications with the purpose to identify and apply information security industry standards,
as mechanisms of protection and prevention,
at three levels or layers:
Physical, personal and organizational. Essentially,
procedures or policies are implemented to tell people
(administrators, users and operators)
how to use
products to ensure
information security within the organizations.
Information security means protecting information and information systems from unauthorized access,
use,
disclosure,
disruption,
modification or destruction.
The termsinformation security,
computer security and information assurance are frequently incorrectly used interchangeably.
These fields are interrelated often and share
the common goals
of
protecting the confidentiality,
integrity and availability of information;
however, there are somesubtle differences between them.
These differences lie primarily in the approach to the subject,
the methodologies used,
and
the areas of concentration.
Information security is concerned with the confidentiality,
integrity and availability of data regardless of the form the data may take:
electronic, print,
or
other forms.
Computer security can focus on ensuring
the
availability and correct operation
of a
computer system without concern for the information
stored or processed
by the computer.
Governments, military, corporations, financial institutions, hospitals, and private businesses amass a great deal of confidential information about their employees, customers, products, research, and financial status.
Most of this information is now collected, processed and stored on electronic computers and transmitted across networks to other computers.Should confidential information about a business' customers or finances or new product line fall into the hands of a competitor, such a breach of security could lead to lost business, law suits or even bankruptcy of the business.
Protecting confidential information is a business requirement, and in many cases also an ethical and legal requirement.

For the individual, information security has a significant effect on privacy, which is viewed very differently in different cultures.
The field of information security has grown and evolved significantly in recent years. As a career choice there are many ways of gaining entry into the field.
It offers many areas for specialization including:
securing network(s)
and allied infrastructure,
securing applications and databases,
security testing,
information systems auditing,
business continuity planning and digital forensics science,
to name a few, which are carried out
by
Information Security Consultants
This article
presents a general overview
of
information security and its core concepts.

History
Since the early days of writing, heads of state and military commanders
understood that it was necessary to provide some mechanism
to protect
the
confidentiality of written correspondence
and
to have some means of detecting tampering.
Julius Caesar
is credited with the invention of the Caesar cipher c50 B.C.,
which was
created in order to prevent his secret messages
from
being read should a message fall into the wrong hands.
World War II brought about many advancements
in
information security and marked the beginning
of the
professional field of information security.
The end of the 20th century and early years of the 21st century saw rapid advancements
intelecommunications,
computing hardware and software,
and data encryption.
The availability of smaller, more powerful and less expensive computing equipment made electronic data processing within the reach of small business and the home user. These computers quickly became interconnected through a network generically called the
Internet or World Wide Web.
The rapid growth and widespread use of electronic data processing and electronic business conducted through the Internet,
along with numerous occurrences of international terrorism,
fueled the need for better methods
of
protecting the computers and the information they store, process and transmit.
The academic disciplines of computer security,
information security and information assurance emerged along with numerous professional organizations -
all sharing the common goals
ofensuring the security and reliability of information systems.
