Computer Security

The protection of information systems is becoming more complicated since it is not only antivirus but intrusion detection, proper setting computer security policies, application of patches to remove vulnerabilities, authentication, security in wireless and VPN links, appropriate policies and mechanisms for backup and recovery, among others.

In the media continually appear news about stealing credit card data, online accounts plundered every cent and various other Internet threats. You may even have been a victim at some point in some similar misfortune. For maximum protection, it does not hurt to be sensitized to these risks and have some basic knowledge about health protection measures to be taken. 

Because Internet use is increasing, more and more companies allow their partners and suppliers to access their information systems. Therefore, it is essential to know what company resources need protection in order to control access to the system and the rights of users of the information system. The same procedures apply when allowing access to the company via the Internet.

In addition, due to the growing trend towards a nomadic lifestyle today, which allows employees to connect to information systems from almost anywhere, employees are asked to part with him information system outside secure infrastructure of the company.

Security objectives

Generally, information systems include all data of a company and also in the material and software resources that enable a company to store and move data. Information systems are essential for companies and must be protected.

Generally , computer security is to ensure that the material and software resources of an organization are used only for the purposes for which they were created and within the framework provided .

Computer security is summarized , usually in five main objectives:

Integrity : Ensuring that data are those who are supposed to be

Confidentiality: ensuring that only authorized individuals have access to resources that are exchanged

Availability : ensuring the proper functioning of information systems

Avoid rejection : ensure you can not deny an operation .

Authentication: ensure that only authorized individuals have access to resources.

In recent times Internet threats have increased and become more rapid and perfected. Antiviruses are necessary but insufficient. Today, computer security, imposes a comprehensive strategy to protect the system from intruders. The multi-program total protection suites can be a good start, not to mention make regular backups. 

A networked system is permanently threatened by malicious software (or malware). A virus is a program that infects other programs, modified and automatically replicates. A worm does not need to infect a file to replicate, and sometimes does constantly to break the system. A Trojan is a program that stays camouflaged in the system and allows access to external users. One spyware or spyware is an application that collects data from the infected computer without the user's knowledge. The junk or spam is bulk email and spam.

Computer security is a topic that many people are not given the importance it really has , many times by the fact consider useless or never used it. But in the modern world , 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.

For this reason there is this book that will help you as far as possible to give you the tools so you can defend against data loss or theft of information in a better way.

But first, I have to do something important Inca foot : Keeping a computer system or computer network intrusions free is no easy task . We must always act with caution and following some basic rules to avoid damage.

Remember , security is inversely proportional to the comfort . If you want a secure system should strive for it , use strong passwords and different and go through a process to maintain the system .
