IT security and computer attack: how do we protect ourselves?

In a constantly expanding digital era, computer security is becoming increasingly crucial. The more we depend on technology, the risks relating to cyber attacks increase. But what are these attacks and how can we protect ourselves from them? Well, stay with us because we prepared all your answers!

What is a computer attack?

A computer attack is an attempt to obtain unauthorized access to a computer, IT system or network with the intention of causing damage. The IT attacks aim to deactivate, interrupt, destroy or control computer systems or modify, block, delete, manage or steal the data held in these systems.
The IT attacks take place for various reasons, but essentially they are harmful. Here are some of the main reasons:

1. Financial reasons: One of the most common reasons why computer attacks occur is the desire for financial income. Hacker can steal credit or debit data from the victims and use them to make illegal purchases.
2. Sabotage: Some IT attacks are intended to cause disorders or damage. This can be a form of digital vandalization or an attempt to interrupt the functioning of an organization or service.
3. Espionage: IT attacks can also be a spy tool. Attacrators can be interested in obtaining confidential information, such as industrial secrets or national security data.
4. Propaganda and disinformation: In the political context, IT attacks can be used to spread propaganda or to influence public opinions through disinformation.
5. Demonstrate technical skills: Some IT attacks are simply performed as a demonstration of technical skills. Hackers can see what they are able to do or test their skills against complex security systems.

Types of computer attacks

Cyber ​​attacks can take many forms, depending on the objectives of the attackers and techniques used. Here are some of the most common types of IT attacks:

1. Malware: These attacks involve the introduction of harmful software in the victim’s system. It can spy on, steal data, crypte files or even take control of the system.
2. DDOS (Denial of Service distributed): These attacks provide for the overload of a network or server with traffic not necessary to do it. The aim is to interrupt the services offered by it.
3. Phishing: These attacks provide the attempt to obtain sensitive information, as a username, password or credit card details, via e -mail or messages that seem to come from a reliable source.
4. Ransomware: These involve the use of a type of malware that encrypts files on a system and requires a refund to unlock them. The victims are often left with the choice between paying for reimbursement or losing access to their data.
5. SQL injection: These involve the exploitation of vulnerabilities in a web application to manipulate or extract data from its database.
6. Spoofing: These attacks provide for the falsification of an identity or address to seem a reliable source. For example, an attacker can send an and -mail that seems to come from a reliable company to try to get sensitive information.
7. Injection of the code: These attacks involve the inclusion of harmful code in an app or a system. The code entered can cause various types of damage, from disturbing the operation of the system to obtaining a complete control over it.

What is computer security?

Cyber ​​security is the practice of defending computers, servers, mobile devices, electronic systems, networks and data of harmful attacks. It is also known as the safety of the information technology or the safety of electronic information. The term is applied in a variety of contexts, from business to mobile computers and can be divided into different common categories.
In today’s digital world, we cannot ignore computer security. A single violation of security can lead to the exposure of personal information of millions of people. These violations have a strong financial impact on companies and also the loss of customer trust. Therefore, computer security is essential to protect companies and people from spammer and cyber criminals.

Types of IT security

1. Network safety: This type of safety focuses on the protection of networks from attacks or intrusions. This includes the implementation of measures such as firewall, intrusions prevention systems and access control to the network.
2. Application safety: It focuses on the protection of software and applications from threats. This may involve the use of safety codes, the update of patch and other measures to prevent vulnerability.
3. Information security: Protects the integrity and confidentiality of data, both at rest and in transit. It includes data encryption, access management and other measures to prevent unauthorized access to information.
4. Operational security: It involves processes and decisions for manipulation and protection of data. It includes data protection policies, classification of information and procedures for the management of sensitive information.
5. Cloud safety: This type of security concerns the protection of data stored in the cloud. It includes security measures, such as two -factor authentication, data encryption and protection for data loss.
6. Final user safety: It refers to security measures that help users maintain the security of systems and data when using final devices, such as computers and mobile devices. This includes the training of users on good practices, how to avoid suspicious EE -Phishing and email websites.

Computer security guide

Protecting from cyber attacks is essential to defend your personal, financial and commercial information, to maintain your private life safely and on a wider scale, to ensure the stability of the infrastructure. We present some useful suggestions to create a safer space in the digital environment:

1. Update your normal software: Make sure all operating systems and applications are always updated to the latest version. These updates often include security patches that can protect you from recent threats.
2. Use a reliable security platform: Use a reliable antivirus program and make sure it is set to update and scan the normal system.
3. Discover the phishing: Phishing attacks are very common and can be devastating. Find out how to recognize an e -mail of phishing and never open attachments or suspicious links.
4. Use strong passwords: Passwords should be long, complex and unique for each account. Take into consideration the use of a password manager to help protect all passwords.
5. Activate authentication in two steps: This further level of security requires two forms of identification to access your accounts. This usually means your password and a unique code sent via text OE -mail.
6. Be aware of the information you share online: Personal information can be collected by the attackers to launch social engineering attacks.
7. Use a private virtual network (VPN): VPN encrypts your Internet connection, protecting from attackers who try to intercept the data.
