Sure! Here's a detailed 16-mark response on the topic "Web Security", with emphasis on key concepts,
threats, and protection mechanisms, structured under appropriate headings.
Web Security
Web security refers to the protective measures and protocols implemented to safeguard websites, web
applications, and web services from various cyber threats and attacks. As the internet becomes
increasingly central to business and communication, ensuring the confidentiality, integrity, and
availability of web-based systems is critical.
1. Importance of Web Security
Protects sensitive data: Web security prevents unauthorized access to sensitive information like
login credentials, credit card details, and personal data.
Maintains user trust: Ensures a secure environment for users, thereby maintaining trust and
reputation.
Prevents financial loss: Avoids economic damages due to data breaches, ransomware attacks, or
downtime.
Regulatory compliance: Meets security standards set by regulations such as GDPR, HIPAA, and
PCI-DSS.
2. Common Web Threats
Threat Description
SQL Injection (SQLi) Attacker inserts malicious SQL queries to manipulate databases.
Cross-Site Scripting (XSS) Injects malicious scripts into web pages viewed by users.
Cross-Site Request Forgery
Tricks users into performing actions without their consent.
(CSRF)
Session Hijacking Steals session tokens to impersonate legitimate users.
Intercepts communication between client and server to eavesdrop or alter
Man-in-the-Middle (MitM)
data.
Overwhelms the server with traffic, causing denial of service to legitimate

users.
3. Security Measures and Best Practices

a. Secure Coding Practices
Validate and sanitize all user inputs to prevent injection attacks.
Use parameterized queries or ORM frameworks for database operations.
b. Authentication and Authorization
Implement multi-factor authentication (MFA).
Use strong password policies and session timeout mechanisms.
Apply role-based access control (RBAC) to limit access privileges.
c. HTTPS and SSL/TLS
Use HTTPS to encrypt data in transit.
Secure server certificates to establish trusted connections.
d. Web Application Firewalls (WAFs)
Filters and monitors HTTP traffic to and from a web application.
Protects against common exploits like XSS, SQLi, and CSRF.
e. Content Security Policy (CSP)
Prevents XSS by restricting sources of executable scripts.
f. Regular Security Audits
Conduct vulnerability assessments and penetration testing.
Keep web servers and applications up to date with the latest patches.
4. Tools for Web Security
Tool Purpose
OWASP ZAP Finds vulnerabilities in web applications
Burp Suite Performs penetration testing
Nessus Network vulnerability scanning
Acunetix Automated web vulnerability scanner
Let’s Encrypt Provides free SSL/TLS certificates
5. OWASP Top 10
The OWASP Top 10 is a standard awareness document for developers and web security professionals. It
lists the ten most critical web application security risks, such as:
Injection

Broken Authentication
Sensitive Data Exposure
Security Misconfiguration
Insecure Deserialization
Understanding and addressing these risks is fundamental for securing web applications.
Conclusion
Web security is a critical component of any online presence. With the rise in cyber threats, it is
imperative for developers, administrators, and organizations to implement comprehensive security
protocols, adopt best practices, and stay updated with the latest vulnerabilities. Ensuring web security
not only protects data and systems but also preserves trust and business continuity.
