WHAT IS THE BEST WAY TO PREVENT A CYBER ATTACK?

-

The key to detecting and stopping computer intrusions is understanding how a cyberattack process works. This cycle, known as Cyber kill chain, establishes the steps that follow a cybercriminal to achieve its objective.   

Ways to prevent a cyber attack
Knowing the seven phases of this chain is the best way to prevent a cyber-attack, as if caught intrusion in any of these stages, the sequence is broken and the attack would be blocked:

Recognition: The attacker collects information about his victim, observing the data that the company publishes and investigating the technology that it uses. That is why it is essential to limit the information that is shared on the network and on social networks. 

Preparation: In this phase the attack is prepared by interacting with the objective. For example, the cybercriminal could create an infected document and include it in an email that impersonates a trusted person in the company. 

Distribution:  At this stage, the attack is transmitted, for example, by opening the infected file that had previously been sent by mail. 

Exploitation: This step supposes the materialization of the attack. It usually occurs by exploiting a vulnerability for which a security patch already exists. This is why it is so important to keep all systems up to date. 

Installation: It is the phase in which the cybercriminal installs the malware or malicious program on the target. Some attacks, such as credential theft, do not require installation.

Command and control:  At this point, the attacker takes control of the system and carries out actions that compromise the victim's privacy: theft of confidential documentation, theft of credentials, etc. 

Actions on the objectives: In the last stage, the cybercriminal seizes the data of his victim and tries to expand his attack to more targets.

The Cyber kill chain is a cyclical process, because if the attacker reaches the last stage can reach new victims and continuous chain. To break it, we must stay up-to-date and take internet security measures to protect our computers.

You should be ready to do that within the security settings. Change the router settings so that the SSID remains hidden and could not be found by potential hackers. Change the name of your network (the Service Set Identifier or SSID) so that hackers cannot guess the manufacturer of the router. Making sure to use a strong password to gain access to your network.

The Internet today allows companies to break down many barriers. The first is the barrier to entry in relation to larger businesses. And it is that although a few years ago small companies were destined to a small growth and to advance with their products only to the market that was geographically closest to them, today an SME can literally compete as equals and sell anywhere in the world 24×7, with the same capacity. In fact, the trend in the medium term is the emergence of micro-multinationals, SMEs that focus on a global market. All can go out into the world. Using the internet in the company also facilitates teleworking and increases productivity within the company, making it efficient and turning its service into a remote one. That it can be handled from anywhere in the world, the trend indicates, that you must become independent of any ties right now.
