Main PC
OS: Windows 10 Enterprise 20H2 64 Bit.
Antivirus: Windows Defender Antivirus (builtin) + common sense.
Firewall: Windows Defender Firewall (builtin).
Virt: Windows Hyper-V Hypervisor running whatever OS currently needed to test / play around with.
HIPS: Windows Defender Tamper Protection / Anti Ransomware and TPM hardware protection.
Encryption: Microsoft BitLocker full disk encryption for OS and data SSDs. VeraCrypt for portable data storage.

Notebook
OS: Linux Mint 20 64 Bit.
Antivirus: None + common sense.
Firewall: I reckon it is most likely iptables / ufw (iptables frontend for easier configuration).
Virt: None. Notebook too weak.
HIPS: None and TPM hardware protection.
Encryption: Full disk encryption using LUKS. VeraCrypt for portable data storage.


Before the OS firewall comes the router firewall which covers all devices. For backup I mostly use Acronis True Image. Overall nothing special to see here.
