What is Cybersecurity?
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. Generally, cyber-attacks are carried out with the purpose of accessing, modifying, or destroying confidential information of users or companies.
Nowadays, the implementation of security measures is mainly due to the fact that there are more connected devices than people, and attackers are becoming more and more creative.
Why is it important?
Today we live in a connected world where everyone benefits from advanced cybersecurity programs on an individual level. A cybersecurity attack can result in identity theft to extortion and loss of personal information.
Everyone relies on critical infrastructures, such as hospitals, financial service entities and others. Protecting these entities from cyber-attacks leads to the proper functioning of society.
- Prevention: The first step is always prevention, which will greatly reduce the risk margin. Therefore, we act early and inform ourselves of everything that can happen to our system.
- Localization: After prevention, in the case of having suffered some kind of problem, it will be necessary to locate where the problem lies. To do this, the best tool is to have powerful mechanisms and tools to help us detect the attack in real time and focus on it immediately. Locating the attack or infection is not as easy as it may seem, since hackers are aware of the use of these mechanisms and tools; what they do is work in such a way that their attacks can go unnoticed.
- Reaction: Once we have located the threat, we will have to give a technical response to it and to do so, the ideal is to follow five steps. We will start by disconnecting the computers from the network and then we will install the appropriate means that can meet the needs and avoid more risks than those incurred. Next, we will carry out a system scan and make changes to all passwords. Finally, it is crucial to carry out a thorough cleaning of the system to check that there is no longer any danger. In the event that confidential data or information has been stolen, we will also have to proceed in the appropriate manner to communicate it to the affected users and elevate what happened to a situation of computer crime.
What is Cyber Attack?
Is the deliberate exploitation of technology-dependent computer systems, businesses and networks. These attacks use malicious code to alter computer logic or data, resulting in damaging consequences that can compromise information and lead to cybercrime, such as identity theft.
Types of Cyberattacks:
- Denial of Service (DoS)
- Cross-Site Scripting (XSS)
When we are victims of a cyberattack, we run through a long list of consequences and possible events that could harm us as a result of this, some of them could be:
- Losing valuable, confidential, or personal information, which may result in financial loss or invasion of privacy, among other things.
- Information about a company and its customers could be leaked, which could result in the bankruptcy of the company and the loss of jobs of all its employees.
- There would be the possibility that private photos or data, which were stored on virtual hard disks, could come to light.
- Some people, such as celebrities, may be exposed to harassment from the media, fans and reporters.
Through any type of hacking, we are exposed to the hindrance in the operation of the equipment, which could mean for a company, an extra expense for the replacement or repair of these devices.
