InfoSec / Cyber

Digital shield representing online filtering and monitoring protecting users from harmful content and cyber threats for child safety.

Filtering and monitoring sit either side of the same boundary. Filtering is preventative, it stops users reaching illegal, inappropriate, or harmful content before they ever see it. Monitoring is reactive, it watches what's actually happening on your network and devices, so concerning activity doesn't go unnoticed. Together, they're one of the few controls that serve both cyber security and child safeguarding at once.

Digital firewall protecting a network with data connections, representing robust perimeter and gateway security.

Day 16 looked at access control from the outside in: securing the connection when staff work beyond school walls. Today we go back to the perimeter itself: the firewall every one of those connections has to pass through, and the network behind it. A firewall that's switched on but never reviewed, or a network where one device can talk to everything else, undoes a lot of the good work covered so far this month. Perimeter and gateway security is less glamorous than ransomware or phishing, but it's the layer that decides whether an intrusion stays contained or spreads.

Every attacker chasing a school network has the same goal once they're in: find an account with more power than it needs. A compromised standard user account is a nuisance. A compromised admin account is a takeover, it can touch every system, every dataset, and every piece of security infrastructure built to stop exactly this. It can probably reset passwords.

Digital padlock protecting sensitive data, symbolizing strong access control against phishing and ransomware.

Over the past two weeks, we've covered how attackers get in:  phishing, deepfakes, ransomware, and what to do when they do. Access control is about the layer that decides whether any of that actually works: even a perfectly crafted phishing email or a stolen password is useless to an attacker if the account behind it is properly protected. Today we look at the single most effective access control measure available, where it still falls short, and what's changing.

Preventing Ransomware | October 12

The NCSC advises: "there's no way to completely protect your organisation against malware infection." That's not a reason to give up, it's the reason defence-in-depth exists. Instead of relying on one control to stop everything, you build multiple layers, so that if one fails, the next one catches it, and if an attacker does get in, the damage is contained and recovery is fast.
