How data security encryption is applied

 Data security encryption is primarily used to prevent malicious or negligent parties from accessing sensitive information. Thus, we can say that it is an important tool in cybersecurity, as it makes the use of intercepted data as difficult as possible.


This method can be applied to all types of data protection needs, from confidential information to personal credit card transactions.


Usually, data security encryption takes place with the help of specialized applications. Data encryption software, also known as an encryption algorithm, is used to develop a scheme that, theoretically, can only be broken with large amounts of computing power.


To further understand how encryption works in data security, we need to know that it is a method often applied in two different forms: a symmetric key or an asymmetric key.


A symmetric (or secret) key encrypts and decodes information. This is best used for individual sharing and smaller data sets.


Asymmetric (or public) encryption uses two linked keys: a private one (kept confidential) and a public one (this can be used by anyone to encrypt).

How to apply encryption to your company's data security

As you've seen so far, encryption is very effective in protecting corporate data. It has become increasingly important as well, because now companies are more demanding to protect not only their information, but also that of their customers. In Brazil, the General Data Protection Law is an example of how this charge has increased.

International English Language Testing System (IELTS)

 It has existed for almost 30 years and is one of the most widespread tests around the world. It aims to test a candidate's level of communication in English using four language skills with a real context: oral interpretation (30 minutes), text interpretation (60 minutes), writing (60 minutes) and conversation (15 minutes). Developed by the British Council in partnership with the University of Cambridge, it is applied in 16 cities in Brazil.

However, there are reports that renowned institutions require a score higher than 8. It is also important to say that IELTS is applied in two formats: academic and general training. The academic is aimed at those people who are looking for opportunities to study master's, doctorate and postdoctoral studies abroad. General training, on the other hand, is focused on those who seek professional impr

Prevention and Recovery: How can security tools help?

 Heavy rains, floods, landslides, devastating fires, blackouts that left an entire state without electricity. Unfortunately, the list of disasters that occurred in Brazil during the year 2020 is long. Disasters appear unexpectedly, generating terrible results and, often, irreversible damage. Within a company's scenario, it is not much different. Just as nature is subject to disasters and risks, so are companies. Therefore, information security works to protect data and information within the business environment, through tools and actions that act in the prevention and recovery of data in disaster situations. In this article, you will understand how security tools can help in a disaster scenario, and why it is important to have complete and continuous actions to protect your company's data. There are two reasons why people underestimate threats and risks: ignorance and minimizing results. Although we are in the information age, the significant increase in the cost of data leaks

How to increase visibility and mitigate risks in the corporate network?

 Corporate networks are changing rapidly as companies embark on Digital Transformation, expanding on the Cloud, incorporating IoT devices and increasing wireless access. All of this increases the attack surface, making the environments more complex.  Protecting this new environment and blocking more sophisticated and intelligent cyber threats has been a major challenge for IT. Therefore, it is necessary to invest in tools capable of giving quick and accurate responses to any type of attack. The problem is that, as the context and visibility are compromised by the complexity of the environment, the IT team ends up having trouble screening many alerts at the same time.  As a result, response times are delayed and teams are often unable to accurately screen all alerts, allowing potential threats to go unnoticed. To deal with this new reality, companies need robust and efficient protection solutions, such as Gigamon's ThreatINSIGHT. It is the cloud's first native high-speed network
