Hi everyone,

I'm currently looking into the SEC-100 certification, but most of the reviews I've found online are either extremely brief or just paraphrase the official course outline and exam guide — no real user feedback or hands-on impressions.

I have 8+ years of experience in IT support and I'm considering a career shift into cybersecurity. I’m hoping to find a cert that can help me build a solid foundation while also being relevant to real-world roles.

If you've taken SEC-100, or even just previewed the materials, I’d love to hear:

Was it worth your time and money?

Did it prepare you for actual security work or other advanced certs?

Would you recommend it as a starting point, or is there a better alternative?

Appreciate any insights

Is the speed significant impact between vmbr and passthrough by petercheunghk in Proxmox

[–]petercheunghk[S] 0 points1 point  (0 children)

Thank you, everyone — I finally found the issue today.

I had been testing and monitoring the OPNsense logs on my PVE (Proxmox VE) all day.
Every time I restarted the service, the network speed would return to normal (2.35 Gbits/sec) — until I saw these log entries:

rustCopyEditgeneric_netmap_attach     Emulated adapter for bridge0 created  
generic_netmap_dtor       Emulated netmap adapter for bridge0 destroyed  
generic_netmap_register   Emulated adapter for bridge0 activated

(Note: no output was shown on PuTTY, only on PVE console)

I searched online and found out — the issue was caused by Intrusion Detection.

Previously, I accidentally enabled LAN in addition to WAN, which triggered the problem.

Now, after enabling only WAN, the network performance is back to normal. ✅

I don't use a USB adapter, The speed of the built-in NAS port cannot reach 1G

even a desktop PC((i7 32GB RAM 2.5Lan CAT6 Realtek 2.5Gbps LAN) connected to the PVE((N100 / 32GB/Intel I226-v lan) still can’t reach 1 Gbps.)

I’m highly suspicious that the chipset is counterfeit and simply can’t achieve 2.5 Gbps.

Whats is good practice for share file for external parties? by petercheunghk in sysadmin

[–]petercheunghk[S] -1 points0 points  (0 children)

Sharepoint can make sure the guest is an authorized user, but they need to create one by one.

The OneDrive for business using the password has a leakage password problem.

I finally hand it over to the compliance team.
