The 5 most common gateways for cyberattacks and how to avoid them

In the digital world, protection against cyberattacks is more important than ever. Companies are constantly exposed to threats that can jeopardize their systems and data. But which vulnerabilities are most frequently exploited by attackers? Here, you can discover the five biggest risk factors — and how to protect your company.

1. Security vulnerabilities in software and applications

Over 20,000 new vulnerabilities were reported in 2022 alone - a 25% increase compared to 2021 (CVE Details 2023). Lack of patch management and inadequate lifecycle management are among the main causes.

How to protect yourself:
  • Install regular software updates and patches
  • Activate automatic updates
  • Detect security gaps through continuous monitoring
2. Programming errors: gateway for hackers

Errors in the source code can lead to serious security risks. Known attacks such as SQL injection or cross-site scripting (XSS) exploit such vulnerabilities.

Protective measures:
  • Adhere to secure programming practices
  • Carry out code reviews and security tests
  • Use web application firewalls (WAF)
3. Misconfiguration of IT systems

Common configuration errors, such as the use of default passwords, can give cyber criminals easy access to systems.

Here's how you can protect yourself:
  • Change default passwords immediately
  • Check security configurations regularly
  • Use multi-factor authentication (MFA)
4. Errors in the IT architecture

A lack of network segmentation allows attackers to move laterally within the network and access sensitive data without restriction.

Better security through:
  • Segmenting the network into defined security zones
  • Implementing zero trust models for access control
  • Using firewalls and intrusion detection systems (IDS)
5. The human factor: the biggest security gap

In 2020, around 25% of all data breaches were caused by phishing attacks (Bassett et al., 2021). Social engineering exploits human weaknesses to gain access to sensitive data.

Prevention measures:
  • Provide regular awareness training for employees
  • Coduct simulated phishing tests
  • Use effective spam filters and security software

Conclusion: Proactive protection is crucial
