All companies must be protected against cyberattacks, to avoid vulnerability in their systems and data. But what is a cyber attack? “It is a malicious and deliberate attempt by an individual or an organization to break into the information system of another individual or another organization. Usually, the attacker looks for some kind of benefit with the interruption of the victim's network", Cisco explained on his website.
There is no day, date and time for cyber attacks: at any time, companies can be victims of these cyber crimes. And what the attackers are most after is demanding a ransom for the data that has been stolen.
It is malicious software that is installed on systems or computers, causing damage. They obtain information secretly, filtering the data and endangering the stability of the platforms. It alters the normal functioning of the equipment, making it impossible to work with them.
It is also known as phishing. “It is the practice of sending fraudulent communications that appear to come from reliable sources, usually through email. The goal is to steal sensitive data, such as login and credit card information, or install malware on the victim's machine".
“In this method, an intermediary (the cybercriminal or a malicious tool) is introduced between the victim and the source: an online banking page or an email account. These attacks are really effective and, in turn, very difficult to detect by the user, who is not aware of the damage that he may suffer”, Kaspersky pointed out on his website.
A denial of service (DoS) is a type of cyber attack that floods a computer or network so that it cannot respond to requests. A distributed DoS (DDoS) does the same thing, but the attack originates from a computer network.
One of the most precious pieces of information hackers are looking for is passwords or login keys. By gaining access to a company's systems with the correct password, they can steal an unimaginable amount of data.
It is software that protects your systems from computer viruses. It detects and eliminates them.
"A firewall is a network security device that monitors network traffic - incoming and outgoing - and decides whether to allow or block specific traffic based on a defined set of security rules", Cisco defined on its website.
It is always necessary to have all data and information backed up on hard drives and similar devices so that it can be recovered in the event of any leak or loss.
“Cybersecurity encryption is the conversion of data from a readable format to an encrypted format. Encrypted data can only be read or processed after decryption,” Kaspersky explained.
“Last year 2021 ransomware was extremely active in this type of malware. By 2022, ransomware is expected to be the most lucrative cybercrime. It is likely to see an increase in this type of RaaS-as-a-service attacks that will focus on data leakage for extortion purposes”, they explained on the Ciset portal.
