Linode Server Restrictions for Malicious Activity

I need to implement specific restrictions on my Linode server to protect against malicious activity as soon as possible.

Restrictions to implement:
- Firewall rules to block unauthorized access attempts
- Access control policies to limit access to authorized users only
- Resource limitations to prevent DDoS attacks and malware infections

Malicious activity to protect against:
- DDoS attacks that can overload my server and cause downtime
- Malware infections that can compromise my data and network
- Unauthorized access attempts that can lead to data breaches and security threats

Ideal skills and experience for the job:
- Strong knowledge of Linode server management and security
- Experience in implementing firewall rules, access control policies, and resource limitations
- Expertise in protecting against DDoS attacks, malware infections, and unauthorized access attempts

I need this project completed as soon as possible to ensure the security and stability of my Linode server.
