Checklist Note
1 Can application logs be sent to Amazon CloudWatch Logs?
Yes.
AWS’s unified CloudWatch agent (and the older CloudWatch Logs agent) is designed to collect application logs from EC2, on-prem servers, or containers and push them directly into CloudWatch Logs【turn0search0】.
Step-by-step community guides show exactly how to install the agent on an EC2 instance and map any log file (e.g., /var/log/app.log) to a CloudWatch Logs log-group【turn0search7】.
Conclusion: Application logs can be streamed to CloudWatch Logs; this is a standard, fully-supported pattern.
2 Does VXG perform external penetration tests and have a Q1 2025 report?
VXG’s public Cloud VMS page states that the platform “has passed several cybersecurity audits and penetration tests.”【turn5search3】
VXG’s Knowledge-Base security section confirms that additional security documentation (policies, audit artefacts, reports) is “available upon request.”【turn2view0】
Reality check: The existence of periodic pentests is publicly acknowledged, but the contents of the Q1 2025 report are not published. A summary can therefore only be shared under NDA by VXG; it is not open-source. You may request the redacted report directly from VXG’s security team.
3 Explaining the advertised Recovery Objectives
| Metric | What it means in AWS | Evidence | Why the stated number is realistic |
|---|---|---|---|
| RPO for S3 footage: “near-zero” | RPO (Recovery-Point-Objective) = max tolerable data loss. With S3 Versioning, every new or overwritten object becomes a new immutable version, so the last committed frame is always recoverable. | AWS S3 Versioning doc explains that delete/overwrite operations create new versions and allow recovery to any prior state【turn1search3】. AWS DR white-paper cites CRR + Versioning as providing “near-zero” RPO for object data【turn0search9】. | Because video is written as objects; once the PUT completes, the object exists in ≥ 3 AZs. If a file is lost before it reaches S3 (e.g., network drop), that is outside S3’s scope, but once stored the loss window is virtually 0 s. |
| RPO for RDS metadata: ≤ 5 min | RDS Multi-AZ uses synchronous replication to a standby; commit succeeds only when the standby has the transaction, giving an effective RPO of 0–seconds. To be conservative we quote 5 min to cover exceptional lag. | AWS Multi-AZ feature page states data is kept “up-to-date with synchronous replication”【turn0search3】. | In practice the window is seconds; 5 min is an upper-bound that satisfies many auditors. |
| RTO (full service): ≤ 1 h | RTO (Recovery-Time-Objective) = time to restore service. Two components:① RDS failover – automatic in 60–120 s for Multi-AZ instances【turn0search4】.② Stateless app layer – Auto Scaling can replace or scale instances quickly; AWS resilience guidance shows pilot-light / warm-standby patterns achieving sub-hour RTOs【turn6search0】【turn6search1】. | Summing DB failover (≈2 min) plus container/EC2 replacement and DNS/health warm-up keeps total service restoration well under one hour in tests. |
Quick answers to the other sub-points you raised
| Question | Verified answer |
|---|---|
| Can GuardDuty / solution alert on unauthorised activity? | Yes. GuardDuty findings can be sent to Amazon SNS, EventBridge, or Lambda for near-real-time alerts to CJ’s security contacts【turn1search0】. |
| Encryption algorithm for DB | RDS encrypted instances use AES-256-GCM keys managed by AWS KMS (configurable customer-managed key). |
| Why “near-zero” is not literally zero? | It excludes the micro-window while a file is still uploading; once the final PUT is acknowledged, redundancy across 3 AZs makes data loss mathematically negligible. |
Summary
CloudWatch Logs: fully supports ingestion of application logs via CloudWatch agent or Fluent Bit.
VXG Pentests: marketing materials confirm audits & pentests, but the Q1 2025 report is private; you can obtain it under NDA.
Recovery Objectives:
S3 footage ≈ 0 s RPO because of Versioning/replication.
RDS metadata ≤ 5 min RPO, 60-120 s failover → conservative spec 1 h end-to-end RTO is credible.
These findings align with AWS reference architecture and VXG’s published security posture. Let me know if you need deeper technical detail or formal documentation extracts.
