1. Basic environmental protection

Server/cloud resource management: Resource monitoring for cloud vendors such as Alibaba Cloud and Tencent Cloud, including configuration optimization and cost control of Cloud Virtual Machine, object storage and other products.

Construction and maintenance of running environment: deployment, security configuration, performance tuning and iterative version updates of Debian/CentOS and other environments.

2. Website security protection

Vulnerability scanning and repair: Regularly use professional tools to conduct penetration tests on websites to repair common Web security risks such as SQL injection, XSS cross-site scripting, and file upload vulnerabilities.

Anti-attack system: Configure Anti-DDoS and CC attack prevention strategies, and set up WAF (Web Application Firewall) to intercept malicious traffic.

Trojan inspection and backdoor removal: Monitor file integrity 7x24 hours a day. Once hanging horses, black links or malicious code are found, they will be immediately isolated and completely eliminated.

Rights and account security: Strictly manage server login permissions, implement SSH key login, disable Root remote login, regularly modify background passwords and enable secondary verification.

3. data backup and disaster recovery

Automated backup: Set up full backup (daily), covering website programs, databases and attachments.

Off-site backup: Sync backup files to different cloud storage areas or local physical devices to prevent permanent data loss due to computer room failures.

4. Performance optimization acceleration

Access speed optimization: Improve website response speed through Nginx configuration optimization, PHP performance tuning, slow query analysis and other means.

Site-wide CDN acceleration: Configure the Content Delivery Network to achieve global acceleration of static resources such as pictures, CSS, and JS, and reduce the loading time of the first screen.

Database optimization: Regularly clean up data table fragments, optimize MySQL index structure, deal with deadlock problems, and ensure data read and write efficiency under high concurrency.

Resource compression and merge: Turn on Gzip compression and merge static resources to reduce the number of HTTP requests.

5. Daily operation and maintenance and inspection

7x24-hour monitoring: Monitor hardware indicators such as server CPU, memory, disk IO, and bandwidth, as well as website HTTP status codes and API interface response success rates.

SSL Certificates Management: Responsible for the application, renewal, deployment and expiration warning of SSL Certificates to ensure uninterrupted HTTPS encrypted transmission.

6. Incident Response Service

Rapid troubleshooting: When the website encounters problems such as unaccessibility, page chaos, and business jams, locate the cause as soon as possible and fix it.

7x24-hour technical support: Provide dedicated operation and maintenance engineer support.

Note: Technical support is a long process and requires irregular maintenance. For some minor details during the operation and maintenance process of websites, we will do our best to assist within our capabilities. Thank you.
