To protect yourself, you need to understand the methods used by attackers. We're not talking about fictional Hollywood hackers here, but organised crime with tried-and-tested business models. Attackers often exploit known vulnerabilities or simple human errors as a gateway. Here are the biggest threats and their specific effects:
Attackers often gain access to networks through simple means such as phishing or open security gaps. Once inside the network, they often operate undetected for weeks, stealing sensitive data and only then encrypting your systems – a tactic known as double extortion.
Real-life example: A manufacturing company can no longer access its ERP systems. Production lines are at a standstill and supply chains are disrupted. At the same time, the attackers threaten to publish internal design plans and customer data.
The consequences: operational downtime, blackmail, damage to reputation and possible contractual penalties.
Modern phishing attacks are highly personalised (spear phishing). Attackers use information from LinkedIn or company websites to target their victims. In CEO fraud (boss scam), extreme time pressure and an appeal to authority are used to override rational verification mechanisms.
Practical example: The accounting department receives an email from the supposed managing director with instructions to make an urgent, confidential payment for a company takeover. The email address looks genuine, the tone is appropriate. The money is irretrievably lost.
The consequences: direct financial loss and the compromise of user accounts, which serve as a gateway for far-reaching attacks.
This type of attack is particularly insidious because it often goes undetected for a long time. After attackers gain access to a mailbox using stolen passwords, they study communication patterns so that they can manipulate invoice data or send fraudulent payment instructions at the right moment.
Practical example: The attackers intercept a genuine invoice, change only the IBAN and forward the manipulated invoice. The payment goes to the fraudsters, and the fraud is often only noticed when the next reminder arrives.
The consequences: high financial losses, loss of trade secrets and a massive breach of trust among partners and customers.
Malware: Malicious software (viruses, Trojans) that compromises systems, steals data or paralyses infrastructure without being noticed.
DDoS attacks: The targeted overloading of your websites or servers to disrupt availability for customers and paralyse your business operations.
Insider threats: Risks posed – intentionally or unintentionally – by (former) employees. An often underestimated but critical threat.
Effective defence is a combination of technology, clear processes and trained employees. Here are the key areas of action for protecting your assets – data, applications and systems – everywhere: in the data centre, in the cloud and at the edge.
Technology provides the necessary visibility and automated defence mechanisms to withstand the speed of attacks. The strategic foundation of modern cybersecurity is zero trust architecture. Instead of relying on the outdated castle-and-moat principle, every access – internal and external – is consistently verified. The following technological pillars build on this foundation:
Recommended action: Implement Multi-Factor Authentication (MFA) across your entire organisation. This is the measure that will have the greatest positive impact on your security. Protect administrative accounts with Privileged Access Management (PAM) to strictly control their use.
Robust technology is only as good as the processes that govern its use.
Recommended action: Conduct a tabletop exercise at least once a quarter to simulate a cyberattack with your crisis management team. Also, regularly test whether your backups are actually recoverable according to the 3-2-1 rule (three copies, on two media, one of which is external).
Any technical barrier can be circumvented by a careless click. That is why raising awareness among your employees is essential.
Recommended action: Set up a simple and clearly visible reporting function in your email programme (e.g. a “phishing alert button”) and actively reward high reporting rates.
From information to action: As a central marketplace, it-sa offers you direct access to leading experts and the right solutions for your security strategy.
The it-sa Expo&Congress in Nuremberg is Europe's leading trade fair, transforming the exhibition centre into the ‘Home of IT Security’. This is where decision-makers, experts and providers meet to experience the latest trends and solutions live.
it-sa 365 complements the trade fair as a year-round digital platform. Here you can find information, network and find the right partners for your security strategy 365 days a year.
The cyber world is developing rapidly, driven largely by AI. Attackers are already using AI to generate mass personalised spear phishing emails or even synthetic voices for fraudulent calls. On the other hand, AI is indispensable in defence (e.g. in SIEM and XDR systems) for detecting complex attack patterns in huge amounts of data in real time. Addressing AI risks and protection now is not a nice-to-have, but a must.
Cybersecurity is not a state you can buy, but a continuous process of risk minimisation. It is a strategic ongoing task: continuously adapt to new threats, combine cutting-edge technology with clear processes and a vigilant team. Only this proactive triad brings true digital resilience and secures the future of your business.
The threat landscape is dynamic. Continuous training is the best protection. As a member of the it-sa 365 community, you get exclusive access to knowledge, contacts and solutions related to IT security:
