The most important elements of information security are those techniques that are used to safeguard data and protect privacy of people and organizations.
To understand why these elements are important, it is first necessary to know what information security is and what it is for.. For this reason, we have prepared this article for you so that you can find all the information related to this topic.
We will also explain what the main elements are that you should take into account to better understand what this type of security is. Don’t miss out on anything.
What is information security and what is it for?
It’s called information security. the group of actions that are carried out to anticipate and protect the data that is found in a computer equipment, in a group of them or in any other way. It is used for both individuals and organizations. information security consists of taking all the necessary measures to strengthen the weaknesses of the computer system. This is done to fix bugs and improve anything that prevents third-party attacks.
That is, it has a proactive approach -before the event happens- and other reagent -measures are taken after the inconvenience occurs- in all security techniques. But the data can not only be stored in a computer programming system. Therefore, the concept of information security also covers all aspects and modes related to the storage and protection of the privacy of people’s data.
Put more simply, Information security is the group of techniques that are used to strengthen the computer system and any method of saving data. In this way, it is searched protect information from intruder attack and the damage that can be done by natural forces, such as rain, earthquakes and other action related to nature.
List of the main elements of information security
To differentiate information security of computer security is necessary analyze the main elements that is inside the first concept.
So we will show you below what are those elements that you must take into account when protecting your data:
confidentiality
The confidentiality of information is an aspect that deals with the measures used to protect and not allow access by any unauthorized user to private or sensitive data that may harm people or companies.
In other words, for information security to be efficient, it is necessary that the entities in individuals that manage it do not disclose the data related to people and operations who do the same. These techniques are common in online stores, because they must protect and prevent the disclosure of all customer bank account and credit card data.
Integrity
These elements refer to the security measures that are taken to protect modification and alteration, intentional or not, of data and information. The goal is to achieve precision and also indivisibility of these. This is used for both private and public data. You should not forget that free data is available to everyone and that these can be modified without prior authorization from their owner.
Therefore, integrity is concerned with ensuring that this information is unalterable and accurate so that it can fulfill its function for which it was created. Also, If it is not free data, it is also necessary to keep the stored information unaltered. Since it is understood that the information is the property of the person or company linked to its own creation and that a modification could cause significant damage to its owner.
Availability
Availability is a very important element in information protection. Controllers work to make data available for use anytime by people or computer processes that require it.
To achieve this in computer processes, measures must be taken to avoid . This will ensure that there is no denial of service to users who are authorized at different levels of a network at any time. If there is no availability of information, the security system is imperfectsince the main objective is to protect the data in the best way so that it can be used when the user needs it.
To achieve this objective, it is necessary to incorporate a good control system, which must guarantee that the information is delivered in a timely manner to the different levels of services that need it. This control system is varied and will depend on those levels of users that has a network in question and the existence of mirror servers, data replication and the quality of the equipment involved in the backup.
Authentication
Authentication is the process that is responsible for establishing whether a user is authorized to access protected information. For this reason, this element is related to the integrity that we saw in previous points because it is necessary to find efficient methods and take correct measures to determine and guarantee the ownership of the user who generates the data or accesses it.
With these information security elements Identity theft is combated. You should not forget that this method causes a lot of damage in organizations and in any home device.
Security Services
Security services are methods that are used in any company, through the design of networks, to process information and transfer it in and out of this. With this it seeks avoid interruption in communication and that it reaches the addressee unaltered.
To carry out this element, it is necessary to implement a logical order in the structure and in the sequence of the messages that need to be sent. in these elements different techniques are usedboth in the sender and in the receiver, so that service is not denied. The most frequent is the implementation proof of authenticity of the transferred data. Another technique is the end-to-end data encryption so that by means of cryptography it can be deciphered only by the authorized person.
Within the security service there are two large groups:
- Non-repudiation: also known as I do not repudiate. They are mechanisms used so that both the sender and the receiver of the message do not deny that they have intervened in the communication process. This is standardized in the standards ISO-7498-2.
- Poles in data transmission: It is necessary to establish rules and mechanisms that ensure that the data can be sent in a confidential, complete manner and that it is not repudiated by any of the intervening users. For this, cryptography is used, the logical structure to follow a sequence and the identification of users.
Certification
The certifications are standards endorsed by entities of world prestige in terms of security. Through these techniques, technology standards for the protection of information. This helps people who work as managers, auditors and as independent professionals to develop skills and can be validated through these regulations.
The most important certifications are:
- Certified Ethical Hacker.
- Certified Information Security Manager, ISACA.
- Certified Information Security Manager.
- Certified Information Systems Auditor, ISACA
- Certified Information Systems Security Officer.
- Certified Information Systems Security Professional Certification.
