How do you secure your servers against cyber threats?

Hi everyone,

I'm looking to improve the security of our servers and would like to hear your strategies. What measures do you take to protect your servers from cyber threats? Specifically, I'm curious about how you configure firewalls, what rules and policies you apply, and which Intrusion Detection/Prevention Systems (IDS/IPS) you recommend. How often do you update your server OS and applications to ensure they're secure? What methods do you use to manage and restrict access to your servers? Additionally, how do you handle data encryption both at rest and in transit? How frequently do you perform security audits and vulnerability assessments? Finally, what are your best practices for secure backups?

Looking forward to your insights and any additional tips you might have.

Thanks in advance!
