Techie Tuesday: What’s a Firewall anyway? 🚪🚫
We talk about Firewalls a lot in the IT world, but let’s look at it the Yorkshire way!
Think of a Firewall as the bouncer at the door of your favourite local club. His job is simple: check the guest list.
✅ If you’re on the list (trusted data), you’re in.
❌ If you’re wearing trainers (dodgy software) or your name’s not down, you’re not coming in.
It’s your first line of defence, keeping the troublemakers out of your business network while letting the 'proper' stuff flow through smoothly.
Without a good bouncer, anyone can wander in and cause a mess. Is your digital door properly guarded?
