Practical notes on backup, disaster recovery and infrastructure that has to survive.
A local backup can disappear with the server it protects. Off-site backup adds separation, encryption and a practical recovery path for businesses, agencies and production environments.
Read more →A backup stored beside the production server can disappear with it. Businesses need isolated, encrypted and immutable off-site server backups that support tested recovery when systems fail.
Read more →A practical guide to segmenting servers with VLANs, subnets, security zones and firewall rules, while keeping administration and backups separate from production systems.
Read more →A practical method for assessing a newly disclosed CVE across business and agency environments, prioritising patches, mitigations, communications and recovery without guessing at risk.
Read more →A practical baseline for hardening Linux servers before production, covering access control, patching, firewalls, permissions, monitoring, vulnerability checks and recovery planning.
Read more →A server can answer every uptime check while running outdated software, leaking data or producing unusable backups. Effective monitoring combines availability, security, operational ownership and tested recovery.
Read more →Useful security logs do more than show that an alert fired. They preserve the timeline, identities and actions needed to investigate a cyberattack, contain damage and choose a clean recovery point.
Read more →Database passwords, API keys and connection strings often leak through code, logs, tickets and backups. A practical approach combines secret management, least privilege, encryption and clear response procedures.
Read more →A practical guide to default-deny server firewalls, covering public services, SSH and RDP security, database exposure, IPv6, segmentation, logging and safer backup connectivity.
Read more →The principle of least privilege limits what a compromised account can reach, change or destroy. Here is how to apply it across users, administrators, services, APIs, networks and backups.
Read more →Server patch management is a security control, not routine housekeeping. A structured process helps agencies and businesses reduce vulnerabilities, control downtime and recover safely when updates go wrong.
