Types of cyber threats


Ransomware is malicious software that blocks or encrypts access to data and demands a ransom in exchange for unlocking or recovering it. Attacks of this nature can be extremely destructive to companies, as they can lead to data loss or significant financial losses. Ransomware often spreads through email attachments, fake websites or exploits vulnerabilities in operating systems. Companies should invest in appropriate anti-virus tools and security systems, and conduct regular employee training to raise awareness of this threat.


Phishing is an attempt to extract sensitive information, such as passwords or credit card numbers, by impersonating trusted institutions or individuals. Company employees are often the target of phishing attacks, so it is important that they are aware of this threat and know how to recognize suspicious messages or websites. To protect against phishing, companies can use spam filters, two-factor authentication for access to systems, and regular cybersecurity training.

DDoS attacks

DDoS attacks (distributed denial of service attacks) involve overloading a server or network by sending a large number of requests, leading to unavailability of services to valid users. Attacks of this kind can be used to blackmail companies, extorting a ransom to restore normal operations. To protect against DDoS attacks, companies can use solutions such as CDN (Content Delivery Network) services, network firewalls and network traffic monitoring systems to detect and neutralize attacks early. Regular software updates and security audits are also key to ensuring that a company’s infrastructure is resilient to such threats.

What steps should be taken to prevent a cyber attack?

Education of employees

Employees should be regularly trained in IT security, so that they are aware of potential threats and know how to recognize suspicious situations. The more aware employees are, the less risk they pose to the company. Training can cover topics such as phishing recognition, rules for creating secure passwords, identifying malware, and using secure WiFi networks.

Software update

Regular software updates are crucial for ensuring system security, as they contain security patches and fixes. Outdated software may have known vulnerabilities that can be exploited by attackers. Companies should follow a policy of automatic updates, and monitor the availability of new software versions and install them quickly to ensure continuous protection against threats.

Using strong passwords

It is important that users use strong and unique passwords to log in to their accounts to make it difficult for potential attackers to breach security. Passwords should be long, containing a combination of letters, numbers and special characters. In addition, it is advisable to use different passwords for different accounts and to change passwords regularly, especially after learning of a potential security breach. Using a password manager can also make it easier to manage and generate strong passwords.

IT security best practices

Implementing multi-level security

It is worthwhile to use multi-level security , such as a firewall, antivirus software or monitoring systems, to increase resistance to cyber attacks. By combining different methods of protection, the risk of an attack succeeding can be minimized. The firewall acts as the first line of defense, blocking unwanted network traffic at the network level. Antivirus software, which runs at the host level, scans files and processes for malware. Monitoring systems, on the other hand, track network and system activity, enabling rapid detection of anomalies and response to potential threats.

Make regular backups

Regular data backups are key in the case of ransomware, allowing quick restoration of data in the event of loss or encryption. It is important to keep backups in a secure location, separate from the main system. Regular testing of restore procedures from backups is also important to make sure that the restoration process is effective and efficient when needed.

Monitoring and responding to incidents

It is important to constantly monitor the network and systems for anomalies and respond quickly to detected incidents to limit the damage. Automated monitoring systems can help quickly detect and respond to dangerous situations. Incident response should include quickly isolating infected systems, identifying the causes of the attack, and implementing appropriate corrective measures such as software updates, changing passwords and analyzing event logs. Regular reviews and evaluations of incident response processes are also key to continuous improvement of security strategies.

Tools to protect against cyber attacks

Antivirus software

Antivirus software scans systems for malware and attempts to neutralize or remove it. Good antivirus software should be updated regularly to provide effective protection against the latest threats. Antivirus software updates include virus definitions and malware signatures to detect new types of threats. In addition, modern antivirus solutions often use heuristic technologies and machine learning to detect previously unknown threats.


Firewalls control network traffic by blocking dangerous or suspicious data packets. Firewalls can be used both at the device level and at the network level to provide an additional layer of protection. They work by rules set by the administrator, deciding which connections are allowed and which should be blocked. Firewalls can also include features for content filtering and detecting and blocking DDoS attacks.

Intruder detection systems

Intruder detection systems monitor network and system traffic, identifying and responding to potential threats. Advanced intruder detection systems can use artificial intelligence to analyze user behavior and detect unusual activity. As a result, they are able to identify even new and advanced forms of attacks. Intrusion detection systems can operate in real time, immediately responding to detected threats, or offline, analyzing recorded data to identify patterns and trends related to attacks.
