Bukti:
-
Keeping software (like WordPress, Magento, and their plugins) updated is critical because updates often fix security vulnerabilities and protect systems from attacks.
- Fixes security flaws: Updates patch known vulnerabilities that hackers could exploit.
- Prevents attacks: Outdated software is an easy target for malware and hackers.
- Protects data: Keeps customer and business information safe from breaches.
- Improves stability: Updates fix bugs and make the system run more reliably.
- Ensures compatibility: Keeps plugins and systems working well together.
-
Input validation is the process of checking and controlling the data entered by users to make sure it is safe, correct, and in the expected format before being processed by a system.
- Ensures valid data: Only allows input that matches the required format (e.g., numbers, emails).
- Blocks malicious input: Rejects harmful or unexpected characters and scripts.
- Prevents SQL injection: Stops attackers from inserting malicious SQL code into input fields (like login forms) to access or manipulate the database.
- Improves security overall: Reduces the risk of many types of attacks, not just SQL injection.
-
Using weak or default passwords for admin panels is very risky because it makes it easy for attackers to gain full control of the system.
- Easy to guess: Simple or default passwords are often the first thing hackers try.
- Brute-force attacks: Weak passwords can be cracked quickly using automated tools.
- Unauthorized access: Attackers can log in as admin and take over the system.
- Data breaches: Sensitive business and customer data can be stolen or leaked.
- System damage: Hackers may delete data, change settings, or install malware.
