Background for this topic.
Firewalls are security controls that permit or block network connections according to policy. They can operate at network boundaries, between internal segments, on individual hosts, or in cloud environments. Basic rules use addresses, ports, protocols, and connection state; more advanced firewalls may inspect applications or encrypted traffic where configured. Their purpose is to limit which systems can communicate, not to determine that all permitted traffic is safe.
Security depends heavily on accurate policy and maintenance. Overly broad, obsolete, or conflicting rules can expose services or allow unnecessary lateral movement, while unmanaged administrative interfaces and unpatched firewall software create additional attack surfaces. Practitioners should restrict management access, apply least-privilege rules, review and remove exceptions, and monitor logs for unexpected connections and policy changes. Firewall logs can support investigation, but encryption, evasion, and traffic allowed by policy may limit what the control can detect.
Majority of public-facing devices still unpatched against critical vulns from as far back as 2022 More than 178,000 SonicWall firewalls are still vulnerable to years-old vulnerabilities, an infosec reseacher claims.…
Two flaws discovered a year apart are ostensibly the same with slightly different exploit paths, exposing corporate networks to risk and potential intrusion.
Over 178,000 SonicWall firewalls exposed over the internet are exploitable to at least one of the two security flaws that could be potentially exploited to cause a denial-of-service (DoS) condition and remote code execution (RCE)
Security researchers have found over 178,000 SonicWall next-generation firewalls (NGFW) with the management interface exposed online are vulnerable to denial-of-service (DoS) and potential remote code execution (RCE) attacks. [...]

Infosec academic suggests Beijing’s warning that iThing owners aren’t anonymous deserves attention outside the great firewall, too In June 2023 China made a typically bombastic announcement: operators of short-distance ad hoc networks must ensure they run according to proper socialist principles, and ensure all users divulge their real-world identities.…
