What Is Website Security?
Website security involves the technologies, processes and controls used to protect websites, web applications, servers, databases and connected services from unauthorized access, malicious activity and data loss.
Website security can address:
- Application vulnerabilities
- Unauthorized access
- Account compromise
- Malware
- Data exposure
- API vulnerabilities
- Injection attacks
- Session security
- Access-control weaknesses
- Configuration issues
- Outdated software
- Security monitoring
The appropriate security strategy depends on the website architecture, technology stack, data and business requirements.
Website Security Assessment
A security assessment helps identify potential weaknesses within a website or application. Assessment areas can include:
- Application configuration
- Authentication
- Authorization
- User permissions
- Forms and inputs
- APIs
- Database interactions
- File uploads
- Session management
- Third-party integrations
- Server configuration
- Dependencies
The results can be used to prioritize remediation work.
Web Application Security
Modern web applications often contain more complex functionality than traditional websites. Security considerations can include:
- Authentication
- Authorization
- Input validation
- Session management
- API security
- Database security
- File handling
- Error handling
- Secure configuration
- Dependency management
Security controls should be incorporated into the application architecture.
Secure Website Development
Security can be integrated into the development process from the beginning. Secure development practices can include:
- Input validation
- Output encoding
- Secure authentication
- Authorization checks
- Secure API design
- Encryption where appropriate
- Dependency management
- Secure configuration
- Error handling
- Logging
Building security into the application early can reduce the need for costly remediation later.
Website Vulnerability Assessment
Vulnerability assessment can help identify weaknesses that require attention. Potential assessment areas include:
- Outdated components
- Misconfigurations
- Weak authentication
- Access-control issues
- Exposed services
- Vulnerable dependencies
- Insecure APIs
- Improper data handling
- Common application vulnerabilities
Findings can be categorized according to their potential impact and remediation priority.
Website Malware Detection & Removal
Compromised websites may contain malicious scripts, unauthorized files or injected code. Security support can include:
- Malware investigation
- Suspicious-file identification
- Malicious-code removal
- Compromised-account investigation
- Security configuration review
- Post-cleanup hardening
- Monitoring recommendations
A compromised website should also be investigated for the underlying cause rather than simply having visible malicious files removed.
Website Firewall & Traffic Protection
Web application firewalls and other traffic controls can help identify and block suspicious requests. Depending on the architecture, protection strategies can address:
- Malicious requests
- Automated attacks
- Suspicious traffic
- Application-layer attacks
- Abusive requests

- Secure password storage
- Multi-factor authentication
- Login protection
- Session controls
- Account recovery controls
- Suspicious-login monitoring
Authentication requirements should be appropriate to the sensitivity of the application.
Role-Based Access Control
Authentication alone does not determine what a user is allowed to do. Role-based access control can define permissions for:
- Administrators
- Managers
- Employees
- Customers
- Partners
- Vendors
- Editors
- Support teams
Access should follow the principle of giving users only the permissions they require.
API Security
APIs connect websites and applications with other systems and services. API security can include:
- Authentication
- Authorization
- Token management
- Input validation
- Rate limiting
- Request validation
- Secure transport

API endpoints should expose only the functionality and information required by authorized clients.
Database Security
Databases frequently contain sensitive business and customer information. Database security can include:
- Access controls
- Secure credentials
- Encryption where appropriate
- Query security
- Input validation
- Backup protection
- Database monitoring
- Least-privilege access
Applications should avoid exposing database credentials or unnecessary database functionality to public users.
Data Protection
Websites may process personal, business and transactional information. Security controls can include:
- Data access controls
- Encryption
- Secure transmission
- Data retention considerations
- Backup protection
- Audit logging
- Secure deletion practices
Specific privacy and regulatory requirements vary by business, geography and data type and should be reviewed with appropriate legal or compliance professionals.
SSL & HTTPS Security
HTTPS protects data exchanged between browsers and web servers. Website security services can include:
- SSL/TLS configuration
- HTTPS implementation
- Certificate management
- Secure redirects
- Mixed-content review
- TLS configuration review
HTTPS should be part of a broader security architecture rather than the only security measure.
Secure File Uploads
File-upload functionality can create security risks when not properly controlled. Security measures can include:
- File-type validation
- File-size limits
- Filename controls
- Storage isolation
- Malware scanning
- Access restrictions
- Safe processing
Content Security Policy
Content Security Policy can help control which resources a browser is permitted to load. A properly configured policy can help reduce certain types of browser-based attacks, but implementation should account for scripts, third-party services and application requirements.
