7 Most common types of cyber attacks and how to prevent them
Learn about the 7 most common types of cyber attacks and how to prevent them. Protect your business with expert advice and actionable tips to stay secure.
Cyber attacks are becoming more frequent and sophisticated, targeting businesses of all sizes. According to the UK Government's Cyber Security Breaches Survey 2023, 32% of UK businesses experienced a cyber attack within the last year. Understanding the most common types of cyber attacks is the first step to protecting your organisation. In this article, we’ll explore these threats and provide actionable prevention tips.
1. Phishing attacks
Phishing attacks trick users into revealing sensitive information like passwords or financial data through fake emails or websites. Phishing is responsible for 43% of all cyber incidents, making it one of the most common threats.
How to prevent: Train employees to recognise phishing attempts and use email filtering tools. Learn more about phishing prevention in our guide to preventing common cyber attacks.
2. Ransomware attacks
Ransomware encrypts your data and demands payment for its release. In 2023, ransomware attacks cost UK businesses an estimated £5 billion in damages.
How to prevent: Keep systems updated, back up data regularly, and use advanced endpoint protection. Explore managed cybersecurity services for comprehensive protection.
3. Malware
Malware is malicious software that can steal data, disrupt operations, or give hackers control over your systems. Common types include viruses, worms, and trojans.
How to prevent: Install robust antivirus software, limit user privileges, and conduct regular vulnerability assessments.
4. Distributed denial of service (DDoS) attacks
DDoS attacks overwhelm your servers with traffic, causing systems to crash. These attacks can lead to downtime and financial losses.
How to prevent: Use a content delivery network (CDN), implement firewalls, and monitor traffic patterns. Regular penetration testing can help identify vulnerabilities.
5. Man-in-the-middle (MITM) attacks
MITM attacks occur when hackers intercept communications between two parties, allowing them to steal sensitive data or impersonate users.
How to prevent: Encrypt communications using SSL/TLS protocols, avoid public Wi-Fi, and use VPNs for secure connections.
6. Insider threats
Insider threats can be intentional or accidental and involve employees or contractors who misuse access to systems or data. These threats account for 34% of data breaches.
How to prevent: Implement strict access controls, monitor user activity, and provide cybersecurity training for employees. Learn more about reducing insider threats with managed services.
7. SQL injection
SQL injection attacks exploit vulnerabilities in web applications, allowing hackers to access or manipulate your database.
How to prevent: Regularly update software, validate user inputs, and conduct penetration testing to identify weaknesses.
