Network Security engineers rely and trust the blacklist feeds, whether they get that from minemeld or from mxtoolbox, spanhaus, ipinfo and others. For the most part these are quite accurate, however, hackers are crafty and switch public IP addresses frequently. To keep the databases up to date in real time is extremely challenging, to say the least. So, what can you do to keep up with the ever changing harmful IP addresses? You need to inspect traffic for threats and vulnerabilities on a Palo Alto Networks Firewall. Once the firewall detects the threat and the attacker’s public IP address, the firewall will then automatically add the attacker’s IP address in a Deny firewall rule. Important : You must make sure you are blocking critical, high and medium risk threat at bare minimum. Why do I need to blacklist the attacker’s IP address if my firewall is already blocking threats? The answer is simple, you don’t know what other vulnerabilities the attackers are trying to exploit. The firewa...
Update: 02/10/2021 If you are using threat DB version 8373-6537, the default action now is reset-server. The main objective of Cybersecurity professionals, is to reduce the attack surface, on network connected devices (computers, IoT, hvac, smart UPSs, smart power strips, etc.). Cybersecurity professionals often assume that devices that have no internet connectivity will never be compromised by a hacker. The NAT slipstreaming cyberattack proves this wrong. “ NAT Slipstreaming allows an attacker to remotely access ANY TCP/UDP service bound to ANY system behind a victim’s NAT, bypassing the victim’s NAT/firewall (remote arbitrary firewall pinhole control), all it takes is the victim’s computer to visit the attacker’s website”. Once the victim’s computer visits the website, the attacker’s servers start to scan your network to identify the network connected devices. If your devices have not been patched to mitigate vulnerabilities, the attackers will exploit these to take cont...
