Network and server security

Network security rests on three layers: preventing a breach (firewall, e-mail filtering, updates), limiting the damage when one happens anyway (network segmentation, restricted permissions), and being able to get back into operation (tested backups). We design, deploy and manage these layers for small and medium companies. A security audit starts at CZK 1,090 per hour (about €45).

The third layer is the one most often forgotten. With ransomware it is the backup, not the antivirus, that decides the fate of the company. That is why with every client we verify that backups are not reachable from the same account as production data (otherwise the attacker encrypts those too) and that a restore has actually been tested. An untested backup is not a backup.

Firewall solutions

How a security audit runs

An audit starts by listing what we are actually protecting – which servers, data and services the company cannot run without. Only then does it make sense to examine how well they are secured. We review the firewall configuration and rules for access from outside, the update status of servers and workstations, user permissions, backup settings, and how remote access connects into the network.

The output is a list of findings ordered by severity with an estimate of the effort involved, not a general recommendation to “improve security”. Most findings turn out to be cheap to fix – typically an unused service reachable from the internet, a shared administrator password, or a backup on a disk attached to the very server it is supposed to back up.

The weaknesses we run into most often

  • Backups in the same place as the data – ransomware encrypts both at once.
  • An out-of-warranty server left unpatched – it runs, so nobody touches it; that is exactly why it becomes the way in.
  • A shared administrator password – nobody changes it after an employee leaves, and there is no way to trace who did what.
  • A flat network – every computer can see every server, so one infected workstation puts the whole company at risk.
  • Missing two-factor authentication – for e-mail and remote access, a password alone is no longer enough.
