Security information
    Introduction
Computer security is defined as the set of rules , procedures and tools that are intended to ensure the availability, integrity , confidentiality and proper use of the information residing on an information system .
 Every day more and more malicious people try to access data from our computers.
Unauthorized access to a computer network or equipment located therein may result in most serious cases .
One of the possible consequences of an intrusion is the loss of data. It is frequently and causes many disorders , especially if we are to day backups . And while we are on the day it is not always possible to recover all the data.
Another of the most damaging is the theft of sensitive and confidential information . The disclosure that a company has about its customers demands can lead millions against this , or an example closer to you is to our passwords of email accounts for which exchange information with others.
With the constant evolution of computers is essential to know what resources need to obtain security information systems .
In this report we will discuss the importance of information security, we references to the ways that exist to protect computer systems and the information contained on unauthorized access, damage , modification or destruction.

Computer security, techniques developed to protect individual computers connected in a network from accidental or intentional damage . These damages include hardware malfunction , the physical loss of data and database access by unauthorized persons . Several simple techniques can hamper crime. For example , access to confidential information can avoid destroying the printed information , preventing others can see the computer screen, keeping the information and computers locked tables or removing sensitive documents . However, preventing cybercrime also requires more complex methods. In a system of so-called ' fault tolerant ' two or more computers simultaneously operate redundantly , so that if one part of the system fails the other takes over. Computer viruses are programs, usually destructive , which is entered into the computer ( to read a disc or access a computer network) and can cause loss of information ( programs and data) stored on the hard drive . 

Computer security should set standards to minimize the risks to information or infrastructure. These standards include hours of operation, restrictions on certain locations , approvals , denials , user profiles , plans , protocols and everything you need to allow a good level of security while minimizing the impact on worker performance and organizational generally and as a major contributor to the use of programs by programmers.
Computer security is designed to protect computer assets , among which are the following :
The computational infrastructure : An essential part for the storage and management of information and to the very functioning of the organization. The role of information security in this area is to ensure that the equipment works properly and anticipate in case of failure , theft , arson , boycotts , natural disasters, power failures or any other factor that threatens the infrastructure.
Users : Those who use technological infrastructure , communications area and manage information . Protect the overall system for use by the program can not compromise the security of the information and not the information handled or stored vulnerable.
Information : is the main asset . Use and resides in the computing infrastructure and is used by users.  

Computer security and safety of information technology is the area of computer science that focuses on the computational infrastructure protection and everything to do with this and especially the information contained or circulating. For this there are a number of standards, protocols, methods, rules, tools and laws designed to minimize potential risks to infrastructure or information. Computer security software includes (databases, metadata files), hardware and everything that the organization values ​​(active) and means a risk if confidential information reaches the hands of others, becoming, for example, on insider trading.
Computer security is the discipline that deals with design standards, procedures, methods and techniques designed to make the system safe and reliable information ... 

Information Security
Information security is critical, as it can cause information disclosure when employees publish data on their Facebook accounts, or accidentally expose confidential information. The cost of security breaches of information credibility in monetary and business are high.


All organizations need to use information security to prevent disclosure of intellectual property. This paper discusses examples of inadvertent disclosures (or intentional), and shows how information security can protect data in various environments.

Computer Security
Computer security is the discipline of designing Ranked standards, procedures, methods and techniques, designed to provide safe and reliable for data processing systems.
is to ensure that resources information system (hardware or software) of an organization are used in a manner to be decided and that access to the information contained therein, and modification is possible only to those who are accredited institutions within the limits of their authorization.
For man as an individual, information security has a significant effect regarding your privacy, you can collect different dimensions depending on the culture of it.

The field of information security has grown and evolved significantly since World War II, becoming an accredited career worldwide. This field offers many specialty areas, including information systems auditing, business continuity planning business, digital forensics and administration of safety management systems, among others
