Security Bulletins
Alert monitoring and practical early warning — inspired by the clarity of public CERT-style bulletins, written for HKISG audiences who need dated next steps, not alarm without action.
Early warning with context
Bulletins translate active threats into operator language: what is happening, who is exposed, what to do first, and where to read more. Each entry is risk-labelled, sourced, and reviewed under HKISG editorial rules.
A bulletin should answer: are we affected, and what do we do today?Bulletin design standard
How to use bulletins in your programme
- Assign a bulletin owner who checks new entries within one business day.
- Map each alert to systems, vendors, and business units in your asset inventory.
- Log actions taken — tickets, config changes, comms — for future audit evidence.
- Brief leadership when risk is high or critical; use the board briefing pack for language.
Risk labels explained
- Critical / High: Likely active exploitation or broad exposure — prioritise same-day response.
- Medium: Meaningful risk with mitigations available — schedule within the week.
- Low / Informational: Awareness and hardening opportunities — plan into sprint backlog.

Frequently asked questions
- How often are bulletins published?
- Frequency follows threat activity relevant to Hong Kong operators. Each bulletin carries a publication date and risk label. Subscribe via membership for full library access and programme notifications.
- Is this a substitute for HKCERT?
- No. HKISG bulletins are membership-programme early warnings with practical context. For national CERT coordination and incident reporting, use HKCERT.
- What should we do in the first 24 hours?
- Confirm exposure in your estate, apply listed mitigations, raise monitoring, and brief decision makers with a dated one-page note. Use Incident Response Basics if your playbook is incomplete.
- Who writes and reviews bulletins?
- The Editorial Council maintains standards under Policies & Standards. Technical claims require identifiable sources; corrections are dated and retained.
