How Does Web Security Work?

Web security works by implementing multiple layers of protection to safeguard websites, web applications, and online data from cyber threats. Understanding ‘what is web security’ will help in exploring these techniques or strategies. These strategies function simultaneously to safeguard websites, applications, and sensitive information from cyber threats. Let us learn how web security works below:

1. Encryption

Encryption converts data into coded text to prevent unauthorised access. It ensures that sensitive information, such as passwords and credit card numbers, are only readable by authorised users.

2. Firewalls

Firewalls act as a barrier between trusted networks and potentially harmful ones. They monitor and control incoming and outgoing traffic to block malicious activity.

3. Secure Sockets Layer (SSL)

SSL certificates create secure, encrypted connections between a user’s browser and a website. This helps protect data as it travels across the internet, ensuring safe online transactions.

4. Two-Factor Authentication (2FA)

Two-factor authentication adds an extra layer of security by requiring a second verification step. This ensures that even if someone guesses a password, they cannot easily access an account without additional information.

5. Regular Updates

Updating software and security systems is important to protect against new vulnerabilities. Regular updates fix any weaknesses in web applications that hackers could exploit.

6. Intrusion Detection Systems (IDS)

Intrusion Detection Systems monitor network traffic for signs of suspicious activity or potential threats. They help detect and alert administrators of any unusual or unauthorised behaviour, allowing them to take quick action to prevent risks before they escalate.
