2. INTRODUCTION:
Web apps form the core of our online experiences in
today's interconnected, digitally innovative era.
The increasing reliance on web applications for
communication, commerce, and information exchange
underscores the crucial importance of web application
security.
3. Secure Code Practices: Adhere to secure
code standards, such as OWASPs. Regularly
update and patch frameworks, libraries,
and dependencies.
Input Validation and Sanitization: Utilize
strong input validation to prevent injection
attacks. Validate and sanitize user inputs to
thwart malicious payloads.

SECURITY BEST PRACTICES
4. Authentication and Authorization:
Implement robust authentication
systems, including multi-factor
authentication. Enforce strong
authorization rules to limit user
access appropriately.
Session Management: Use secure
session management methods,
employing secure, random session
identifiers. Implement techniques to
detect and prevent session
hijacking.
5. HTTPS Encryption: Require HTTPS for data encryption between client and server.
Keep SSL/TLS certificates up to date.
Content Security Policy (CSP): Use CSP headers to reduce XSS attack risks. Establish
and enforce a trustworthy source whitelist for content and scripts.
Security Headers: Utilize security headers like Strict-Transport-Security and X-
Frame-Options to enhance security.
Controls for Cross-Origin Resource Sharing (CORS): Implement CORS rules to
restrict domains making requests to the web application. Avoid overly permissive
CORS settings that may expose sensitive data.
Security of File Uploads: Validate and restrict file uploads to prevent malicious file
execution. Employ proper file type verification, size limits, and anti-virus scanning.
6. BENEFITS OF
SECURING WEB
APPLICATION Data Protection and Privacy: Protects sensitive
user data and privacy, enhancing user trust and
compliance with data protection requirements.
Business Continuity and Reputation
Management: Ensures business continuity by
preventing security breaches and downtime,
preserving customer trust and confidence.
Long-Term Cost Savings: Early identification and
correction of security flaws lead to efficient and
cost-effective development, avoiding expenses
associated with data breaches and remediation.
