Cloud firewall planning for internet-facing workloads

Reduce the exposed surface

A firewall policy should describe who can reach a service, on which protocol and port, and why. HostGanga helps customers plan protection around VPS and hosted applications without assuming that every workload needs the same controls.

Start by listing public services such as HTTPS, private services such as a database, and administrator paths such as SSH. Availability of platform-level firewall controls varies by service and location, so confirm the required implementation before ordering.

Purpose-led rules

Map each allowed flow to an application or operational need instead of opening broad port ranges.

Safer administration

Restrict management traffic to known sources where practical and retain a documented recovery path.

Reviewable policy

Keep rule names, ownership, dependencies, and planned expiry dates understandable during later audits.

Build the policy before deployment

Document source, destination, protocol, port, direction, and business purpose for every flow. Place specific rules before broad rules, separate production from testing, and avoid exposing control panels or databases directly to the public internet.

• Allow web traffic only on required ports
• Limit SSH or remote administration sources
• Record temporary exceptions and removal dates

Operate without locking yourself out

Test one change at a time, keep an existing session open during management-rule updates, and verify both allowed and denied paths. For multi-server applications, include health checks, monitoring, backups, and internal service communication in the design.
