In today's digital world, cyber security is crucial for companies. As companies become more connected and use more technology, the number and complexity of threats increases. Cybercriminals use various methods to attack companies and steal sensitive information. Data to steal or manipulate. It is therefore essential that companies take measures to protect their IT infrastructure and guard against cyber attacks.
Threats on the Internet: How companies can be attacked
There are various ways in which companies can be attacked on the Internet. One of the most common methods is Phishingwhere cybercriminals use fake emails or websites to steal confidential information such as usernames, passwords or credit card details. Another common target is ransomware attacks, in which cybercriminals encrypt a company's data and demand a ransom to release it again. In addition, companies can also fall victim to distributed denial of service (DDoS) attacks, in which a company's IT infrastructure is paralysed by network overload.
In recent years, there have been several high-profile attacks on companies that have shown just how devastating the impact of a cyber attack can be. One example is the attack on the US retail chain Target in 2013, in which the data of millions of customers was stolen. Another example is the attack on the credit counselling company Equifax in 2017, in which the personal data of over 140 million people was stolen. These incidents have shown that no company is immune to cyber attacks and that the impact of such attacks can be far-reaching.
Cybersecurity: why it is essential for companies
The impact of a cyberattack on a company can be devastating. In addition to the financial losses that can result from the theft of money or sensitive information, an attack can also shake the confidence of customers and partners in the company. This can lead to a considerable loss of image and have a long-term impact on the business.
In addition, many companies are required by law to comply with certain data protection standards and to Security of their IT infrastructure. Violations of these regulations can result in heavy fines. It is therefore crucial that companies take appropriate measures to protect their IT systems and ensure that they comply with the applicable regulations.
Phishing, ransomware and the like: an overview of the most common types of attack
| Type of attack | Description of the | Example |
|---|---|---|
| Phishing | The interception of sensitive data through fake emails or websites. | A fake e-mail from the bank asking the recipient to enter their login details. |
| Ransomware | A kind of Malwarewhich blocks access to the computer or certain files and demands a ransom. | A pop-up window that asks the user to pay a certain amount to restore access to the computer. |
| Man-in-the-middle attack | An attack in which an attacker intercepts and manipulates communication between two parties. | An attacker who intervenes between the user and the website and intercepts or manipulates the data. |
| Denial of service attack | An attack in which a server or website is paralysed by an overload. | A large number of requests to a website that results in the site no longer being accessible. |
There are various types of cyber attacks that can threaten companies. One of the most common methods is phishing, where cybercriminals use fake emails or websites to steal confidential information. In a phishing attack, for example, an employee may receive an email purporting to be from a trusted sender such as a bank or colleague. In the email, the employee is asked to click on a link or enter their login details. If the employee does this, the attackers gain access to their confidential information.
Another common method of attack is ransomware. In a ransomware attack, cybercriminals encrypt a company's data and demand a ransom to release it again. This can lead to significant financial losses as the company may not be able to access its data until the ransom is paid.
Companies can also fall victim to Distributed Denial of Service (DDoS) attacks. In a DDoS attack, attackers flood the Network of a company with a large number of requests, causing the network to become overloaded and stop working. This can lead to significant downtime and affect a company's bottom line.
IT security: How you can protect your company from attacks

It is also important that companies regularly train their employees and inform them about the risks of cyber attacks. Employees should be educated on how to recognise phishing emails and how to protect themselves from ransomware attacks. In addition, companies should also have guidelines for handling sensitive information to ensure that employees protect confidential data appropriately.
Data security: Why protecting sensitive information is so important
Protecting sensitive information is of crucial importance for companies. A data leak can not only result in financial losses, but can also shake the trust of customers and partners in the company. In addition, companies may be legally obliged to comply with certain data protection standards and ensure the protection of sensitive information.
Encryption is one way of protecting sensitive information. Encrypting data ensures that it can only be read by authorised persons. This can help to Risk of a data leak and to ensure the security of sensitive information.
Employees as a risk factor: How you can sensitise your employees to the issue
Employees can inadvertently contribute to a company being exposed to a cyber attack. For example, they may respond to phishing emails or inadvertently disclose confidential information. It is therefore important that companies regularly train their employees and inform them about the risks of cyber attacks.
One way to sensitise employees to the topic is to carry out training and courses. Employees should be educated on how to recognise phishing emails and how to protect themselves from ransomware attacks. In addition, companies should also have clear guidelines for handling sensitive information and ensure that employees understand and follow these guidelines.
Security guidelines: Why clear rules are important when dealing with IT security
Clear guidelines for dealing with IT security are of crucial importance for companies. Clear rules ensure that employees knowhow they should behave with regard to IT security and that they understand the risks of cyber attacks.
One way of establishing clear guidelines implementis the creation of an IT security guide. This guide should set out the key security measures and procedures that employees must follow. In addition, organisations should ensure that employees are regularly audited to ensure that they understand and follow the guidelines.
Emergency plan: How to react quickly and effectively in an emergency
It is important that companies have an emergency plan in place to be able to react quickly and effectively in the event of an emergency. An emergency plan should define who needs to be notified in the event of a cyber attack and what measures need to be taken to contain the attack and minimise the impact.
Regular data backups are an important part of an emergency plan. By making regular backups, companies can ensure that they can restore their data in the event of a data loss. In addition, companies should also ensure that they have the necessary resources to respond to an attack, e.g. by working with an IT security service provider.
External help: when you should call in an IT security service provider
In some cases, it may be necessary to call in an IT security service provider to ensure the security of an organisation. An IT security service provider has the expertise and resources to help companies identify and defend against cyber attacks.
An IT security service provider can help companies to Implementation of security measures, such as the establishment of a Firewall or carrying out penetration tests. In addition, an IT security service provider can also help to monitor a company's IT infrastructure and recognise suspicious activities.
