@callreddington Nothing yet, I'm afraid. Finding a new sponsor for such a high-value production isn't easy 🤷

@ranlevi anything in the works after Malicious Life ?

I'll be releasing 2 episodes of Darknet Diaries this month, instead of the normal 1 per month.

No one’s doing any April fools prank in the cybersecurity community?

Hot Take: What if this is how the KitKat heist was done 🤔🤔 #Kitkat

@prettycyb3rgirl I wish Michael Bazel would come back @IntelTechniques was awesome podcast especially on Personal Security

@prettycyb3rgirl @DarknetDiaries got me hooked up to listening to podcasts on commute it's been 4yrs

Linux Firewall Configuration 1. Introduction → A firewall is a security system that controls incoming and outgoing network traffic. → It acts as a barrier between trusted internal systems and untrusted external networks. → In Linux, firewalls help protect servers, applications, and data from unauthorized access. 2. Why Firewall Configuration Matters → Prevent unauthorized access to your system. → Protect against network-based attacks. → Control which services are exposed to the internet. → Monitor and filter traffic based on rules. → Strengthen overall system security. 3. Types of Linux Firewall Tools → iptables → Traditional and powerful firewall tool. → Uses rule chains to filter traffic. → Operates at a low level in the kernel. → nftables → Modern replacement for iptables. → Simplified syntax and better performance. → Supports advanced rule management. → UFW (Uncomplicated Firewall) → Beginner-friendly firewall interface. → Built on top of iptables. → Easy to configure and manage. 4. Firewall Concepts → Rules → Define what traffic is allowed or blocked. → Example: → Allow SSH (port 22) → Block all other incoming traffic → Chains → Rules are organized into chains: → INPUT → Incoming traffic → OUTPUT → Outgoing traffic → FORWARD → Traffic passing through system → Policies → Default action for traffic: → ACCEPT → Allow traffic → DROP → Block traffic silently → REJECT → Block traffic with response 5. Using UFW (Simple Approach) → Enable Firewall → sudo ufw enable → Allow a Service → sudo ufw allow ssh → Allow a Port → sudo ufw allow 80 → Deny a Port → sudo ufw deny 21 → Check Status → sudo ufw status 6. Using iptables (Advanced Control) → Allow SSH → iptables -A INPUT -p tcp --dport 22 -j ACCEPT → Allow HTTP → iptables -A INPUT -p tcp --dport 80 -j ACCEPT → Drop All Other Traffic → iptables -A INPUT -j DROP → Save Rules → iptables-save 7. Using nftables (Modern Approach) → Create Basic Rule → nft add rule inet filter input tcp dport 22 accept → List Rules → nft list ruleset → Flush Rules → nft flush ruleset 8. Common Firewall Configuration Strategy → Allow essential services (SSH, HTTP, HTTPS). → Deny all unnecessary ports. → Restrict access to trusted IP addresses. → Enable logging for suspicious traffic. → Apply least privilege principle. 9. Firewall Logging → Monitor blocked and allowed traffic. → Helps detect attacks or misconfigurations. → Example (UFW logging): → sudo ufw logging on 10. Best Practices → Always allow SSH before enabling firewall (avoid lockout). → Use default deny policy. → Regularly review firewall rules. → Keep firewall tools updated. → Combine firewall with intrusion detection tools. 11. Tip → Linux firewalls are essential for network security. → UFW is simple and beginner-friendly. → iptables provides deep control. → nftables offers modern and efficient rule management. → Proper configuration protects systems from unauthorized access. 📘 Linux Mastery Ebook → Master Linux internals, security, firewall configuration, system monitoring, and architecture step-by-step. 🔗 Grab the Linux Mastery Ebook: codewithdhanian.gumroad.com/l/dynwdc

@DrKanyuira Raspberry PI could be a viable option, Opensense could run on a microtik if you want DIY

@callreddington I just need a router that can run a VPN, not necesarily trave one.

Who among you guys has experience with these portable routers that can run a VPN? I'm considering one to run the VPN on instead of installing on devices.
