A cyber attack is a deliberate attempt to disrupt, spy on, alter or destroy computers, networks or data.
Attacks are carried out by criminals, activists, insiders or state groups.
Types of Cyber Attacks
Methods range from malware and deception to overloading services.
Two forms are particularly common.
Malware Attacks
Malware is malicious software such as viruses, trojans, spyware and ransomware.
It reaches devices through attachments, downloads or security holes and steals or encrypts data there.
Phishing Attacks
Phishing deceives people with fake emails, messages or websites.
The goal is to obtain credentials, payment details or a click that installs malware.
Prevention of Cyber Attacks
Protection comes from technology and people who know the risks.
Use of Security Software
Firewalls, antivirus, spam filters and current updates stop many attacks.
Two-factor sign-in protects accounts, and forms should be secured against automated attacks with bot protection such as CDPCaptcha.
Education and Awareness
Regular training helps people recognise phishing and social engineering.
Clear reporting channels ensure that suspicious cases become known early.
Impact of Cyber Attacks
The consequences affect individuals as well as companies and public bodies.
Financial Impact
Costs arise from ransom, business interruption, recovery, legal advice and fines.
For small companies a single attack can threaten their existence.
Reputational Impact
Customers and partners lose trust when data leaks or services fail.
The damage to reputation often lasts longer than the technical damage.
Conclusion
Cyber attacks have become an everyday occurrence.
Current technology, trained staff and an incident plan stop most of them or contain them quickly.
