Cyber attacks: here is what they are and how they work

When we talk about cyber attacks, we are generally referring to all of those operations, normally in anonymous form, aimed at striking computer system, networks or infrastructures for the purpose of information theft or destruction.

There are many types of cyber attacks, but usually the primary purpose is always to knock out the victims’ network and terminals, then moving on to the extortion of sums of money as ransom and generating a sentiment of collective fear.

The concept of collective fear degenerates into a sort of negative publicity for the network that is hit by the attack, leading to an increase of losses even after the systems have been restored.

One of the most frequent types of cyber attacks is the “Distributed Denial of Service” (DdoS).
This consists in the generation of incoming traffic that literally overruns a computer network on multiple fronts.
This is none other than a sort of “flood” for a network and therefore for all the devices connected to it. For this reason, once a DdoS attack is launched it becomes impossible to stop it by switching off the single source.

Having advanced cyber security systems on a corporate level has by now become a necessity and fundamental in order to prevent running into problems that can escalate into serious situations.
This is the case especially if we consider the historic era in which we live – the Internet of things. This is a time when everything is connected. Each device is and will always be managed over a network. This is why it is increasingly essential to defend this network and safeguard its operation.

What measures to take into consideration to avoid cyber attacks?

  • Update your username and password frequently in order to make them more secure and constantly update the operating systems and applications that are exposed to the Internet, with particular attention to their configuration.
  • Correctly configure firewalls, opening only the necessary ports and protocols, particularly for those companies that offer their services over the Internet such as banks or administrations.
  • Increase the general level of Cyber Security culture in general, implementing awareness courses and processes for employees.
  • Create a dedicated Internet connection for company guests in order not to have to provide strictly business credentials, thereby safeguarding company’s network security and above all its sensitive data.

For more detailed information on the subject, in this article, you can find the complete Vuetel guide for cyber security.

cyber attack is any manoeuvre used by individuals or organisations, including state-run organisations, which strike computer systems, infrastructures or computer networks and/or personal electronic devices through malicious acts, generally from an anonymous source, for the purpose of theft, alteration or destruction of specific objectives, violating susceptible systems. These actions can be classified as cybercampaigns, cyberwarfare or cyberterrorism, depending on the context. Cyberattacks range from installation Spyware on a PC up to and including the demolition of the infrastructures of entire nations.
