Common causes
Why do breaches happen?
01
Weak or reused passwords
80% of breaches involve compromised credentials.
02
Unpatched software
Known vulnerabilities that a simple patch would have prevented.
03
Phishing and social engineering
Deceiving the employee is still the favourite way in.
04
Lack of encryption
Sensitive data stored or sent without protection.
05
Misconfigurations
Databases and services exposed to the internet by oversight.
06
No backups
Without backups, ransomware can be definitive.
