Linux security and networking
Hardened servers and properly configured networking: the layer most often left at defaults and most often exploited.
What this covers
Server hardening, firewall and iptables configuration, SSH lockdown, user and permission models, and service isolation, alongside network configuration covering routing, VLANs and VPN connectivity.
Most Linux compromises exploit configuration that was left at its default rather than an unknown vulnerability. This is the work that closes that gap, and it is the work most often skipped when a server is stood up in a hurry.
What’s included
- Server hardening against a defined baseline
- Firewall and iptables configuration
- SSH lockdown and key-based access
- User, group and permission models
- Service isolation and least-privilege configuration
- Routing, VLAN segmentation and VPN connectivity
Pairs with our Cyber Security services where a wider security programme is needed.
Every implementation can be backed by a 24/7/365 SLA support and maintenance agreement covering monitoring, incident response, configuration changes and platform updates, on-site or remote.
