Looking to lock down your network? Honestly, securing your home network isn’t rocket science, it’s just a matter of knowing which tools to use. Enter Gibson Research CorporationGRC)—your DIY toolkit for network security. Their stuff just works, without needing you to be a computer whiz. First up, check out ShieldsUP! This is your go-to for scanning vulnerabilities. It basically pokes around your network to see what doors are left open aka ports. Open ports are like flashing neon signs for hackers; not good. Closed ports might seem better, but they still could give hackers a hint about your network. Stealth mode? That’s the James Bond of settings, flying under the radar.
You’ll want to run the File Sharing test, which checks port 139—seriously, this NetBIOS stuff needs to be locked down. And the Common Ports test? It looks at FTP, SSH, HTTP, HTTPS—the usual suspects. Find anything open that you didn’t open yourself? Time to pull out the firewall and lock it down. For real. Don’t skip the All Service Ports test, either; it scans ports 0 to 1055. Sounds boring but worth it. While you’re at it, the UPnP exposure test is a must; you do not want that exposed to the internet.
GRC isn’t just about scanning ports. Their Perfect Passwords tool is like having your own bouncer—it spits out super-strong passwords that are impossible to guess. We’re talking hexadecimal strings, letters, numbers—the kind of stuff that makes hackers cry. Also, Password Haystack explores how long it would take to crack a password. Pretty handy when you need to find that Goldilocks zone for password length on finicky websites.
So, about DNS resolvers; they’re often overlooked but can be weak spots for cache poisoning attacks. GRC’s DNS Spoofability test will help check if your DNS resolver is actually safe. Run it; avoid the drama. Beyond that, they’ve got other nifty tools. Paper Perfect Passwords for super-secure MFA codes, Inspectre for checking your device against Meltdown and Spectre vulnerabilities, and IsBootSecure to find out if your motherboard is playing nice in secure mode.
The whole GRC site is a treasure trove for anyone who cares about network protection. It’s not the flashiest site on the web, but every tool there gets the job done. So, there you have it—network security isn’t cinematic, but it’s crucial. And these tools make you the star in your home’s own cybersecurity show.
