1. Purpose
The purpose of this policy is to establish standard practices and guidelines for implementing security measures to prevent unauthorized attacks, such as Web Application Firewall (WAF) and Distributed Denial of Service (DDoS) attacks. This policy outlines the necessary security measures for protecting Igile Technologies India Pvt Ltd’s information systems, applications, and data from external threats and ensuring the integrity, availability, and confidentiality of our systems.
2. Scope
This policy applies to all employees, contractors, consultants, and third-party vendors of Igile Technologies India Pvt Ltd who manage, maintain, or access the company's information systems, networks, and data. This policy covers all systems, applications, and networks, both on-premises and cloud-based.
3. Objectives
- To establish security measures for preventing unauthorized access and attacks.
- To define the use of Web Application Firewall (WAF) and Distributed Denial of Service (DDoS) protection measures.
- To implement access control mechanisms and firewall policies for enhanced security.
- To ensure compliance with industry standards and regulatory requirements.
4. Definitions
- Web Application Firewall (WAF): A security solution that monitors and filters incoming traffic to web applications, protecting them from various attacks, such as SQL injection, cross-site scripting (XSS), and other threats.
- Distributed Denial of Service (DDoS): An attack that seeks to make an online service unavailable by overwhelming it with traffic from multiple sources.
- Firewall: A network security device or software designed to prevent unauthorized access to or from a private network.
5. Policy Statements
- Mandatory WAF Usage: All web applications hosted by Igile Technologies must be protected by a Web Application Firewall (WAF). The WAF must be configured to protect against common web vulnerabilities, such as SQL injection, XSS, and OWASP Top 10 threats.
- Configuration and Management: The WAF must be configured to provide real-time monitoring and automatic blocking of malicious traffic. Rules and policies must be updated regularly to ensure protection against the latest threats.
- Logging and Monitoring: All WAF activities, including blocked requests and alerts, must be logged and monitored continuously. Logs should be retained for at least one year for auditing and forensic purposes.
- Regular Testing: The effectiveness of the WAF must be tested regularly through penetration testing and vulnerability assessments to identify and remediate potential weaknesses.
- DDoS Mitigation Services: Igile Technologies must implement DDoS protection services to detect and mitigate DDoS attacks. These services should be capable of handling large-scale attacks and must provide real-time traffic analysis and automatic traffic filtering.
- Traffic Rate Limiting: Implement rate-limiting controls on all public-facing applications and services to reduce the impact of potential DDoS attacks.
- Redundancy and Load Balancing: Use redundancy and load balancing techniques to distribute traffic across multiple servers and data centers to ensure service availability during an attack.
- Response Plan: Develop and maintain a DDoS response plan, including steps to identify, contain, and mitigate attacks. The plan should be reviewed and updated regularly.
- Least Privilege Principle: All employees, contractors, and third-party vendors must be granted the minimum level of access necessary to perform their job functions. Access must be reviewed periodically and adjusted as needed.
- Multi-Factor Authentication (MFA): Multi-factor authentication must be enforced for all administrative access to servers, applications, and network devices.
- Segregation of Duties: Implement segregation of duties to prevent any individual from having excessive control over critical functions, such as system administration, security, and auditing.
- Access Review and Revocation: Conduct regular access reviews to ensure appropriate access levels are maintained. Access must be revoked immediately upon employee termination or role change.
- Network Segmentation: Implement network segmentation using firewalls to separate sensitive data and applications from less critical systems. This minimizes the impact of potential breaches.
- Inbound and Outbound Rules: Firewalls must be configured with strict inbound and outbound traffic rules to allow only necessary and authorized traffic. All other traffic should be denied by default.
- Logging and Alerts: Firewall activities must be logged, and any unauthorized access attempts should trigger immediate alerts. Logs should be retained for at least one year for auditing purposes.
- Periodic Review: Firewall configurations and rules must be reviewed and updated regularly to ensure they remain effective against new and evolving threats.
6. Roles and Responsibilities
- IT Security Team: Responsible for the implementation, management, and monitoring of WAF, DDoS, and firewall measures. They must ensure that security configurations are updated and maintained regularly.
- System Administrators: Ensure that all servers and applications comply with the security measures defined in this policy. Responsible for implementing access controls and conducting regular access reviews.
- Compliance Team: Ensures that all security measures comply with relevant regulations and industry standards. They are responsible for conducting regular audits and assessments.
- All Employees: Must adhere to the security measures outlined in this policy. Employees must report any suspicious activities or potential security incidents to the IT Security Team immediately.
7. Policy Compliance
Compliance with this policy is mandatory. Failure to comply with this policy may result in disciplinary action, up to and including termination of employment. Any exceptions to this policy must be approved by the Chief Information Security Officer (CISO).
8. Review and Revision
This policy will be reviewed annually or as needed to ensure compliance with applicable laws, regulations, and industry standards. Changes to this policy must be approved by the Chief Information Security Officer (CISO).
