The traditional security model treated the office network as a castle: anyone inside the walls was trusted. Remote work, cloud services and phones broke that model. Zero trust replaces it with a simple rule: verify every request, every time, based on who is asking, from what device, for what.
The principles
- Verify explicitly. Authenticate and authorise every access request using identity, device health and context.
- Least privilege. Give each person and service only the access they need, for only as long as they need it.
- Assume breach. Design so that one compromised account or server cannot reach everything.
Where to start
You can make real progress with a handful of changes:
- Put multi-factor authentication on every account that matters: email, admin panels, cloud consoles, VPN, payment systems.
- Centralise identity. One directory with single sign-on makes it possible to remove someone's access everywhere at once when they leave.
- Remove standing admin rights. Use separate admin accounts, and grant elevated access only when needed.
- Segment your servers. Databases should not be reachable from the internet or from every other server.
- Stop exposing management ports. SSH, RDP and control panels should sit behind a VPN or an access gateway, not open to the world.
- Keep devices updated and encrypted, and decide which devices may access company data.
What zero trust is not
It is not a product you buy. Vendors sell components, such as identity providers, access gateways and endpoint tools, but zero trust is how you combine them. It is also not all-or-nothing; each step reduces risk on its own.
How IDX helps
IDX servers can be deployed with private networking so internal services are never exposed publicly, and VPN access is available as an add-on on Egypt Servers. Our managed services and SOC teams can help design access controls and segmentation that fit how your business actually works.
