A logic bug in widely deployed BIND 9 resolvers—tracked as CVE-2024-4076—can cause named to hit an assertion and terminate when a single client query simultaneously triggers serving stale cache data and requires lookups in local authoritative zone content, creating a remotely exploitable...

Resolver operators and DNS administrators should treat CVE‑2024‑1737 as an urgent operational risk: a BIND 9 flaw that can slow or stall resolver caches and authoritative zone databases when large numbers of resource records (RRs) are concentrated at a single owner name, and ISC has published...

A remotely exploitable flaw in BIND 9 allows a malicious client to flood a server with DNS messages over TCP and drive the process into an unstable, unavailable state — an availability-impacting denial-of-service that can leave resolvers and authoritative servers unresponsive while the attack...

A deep, remotely exploitable flaw in ISC BIND 9’s control-channel parsing can exhaust a process’s stack and crash the DNS daemon named, allowing attackers with network access to the control port to trigger a denial-of-service condition unless systems are patched or access is restricted...

Portmaster is a free, open‑source privacy firewall from Safing that intercepts and visualizes every network connection on your Windows PC, lets you enforce per‑app rules, encrypts DNS by default, and applies system‑wide tracker and malware blocklists — but it also requires careful configuration...

Palo Alto Networks has pushed a clear marker in the SASE arms race with the launch of Prisma SASE 4.0, a major platform refresh that explicitly frames the next phase of enterprise security as AI versus AI — protecting organizations not only from AI-augmented attackers, but from the uncontrolled...

Setting up DNS on a Windows Server is one of the most consequential tasks an administrator can perform: it turns raw IP addresses into human-friendly names, anchors Active Directory functionality, and forms the backbone of service discovery across the network. Proper DNS configuration reduces...

Microsoft has updated guidance in its Security Update Guide advisory ADV200013 — the advisory that covers DNS resolver spoofing and cache‑poisoning attacks — and is explicitly telling administrators that in addition to older server builds the mitigation applies to newer releases such as Windows...

The silent war over corporate Domain Name System (DNS) integrity is intensifying, with global cyber adversaries relentlessly probing for gaps in the digital fabric that connects modern enterprises. In response to this growing threat landscape, Akamai has announced the launch of its DNS Posture...

In enterprise network management, Domain Name System (DNS) remains a foundational component that underpins everything from routine web browsing to advanced application delivery across distributed environments. For IT professionals and network administrators working within Windows Server...

DNS (Domain Name System) is the backbone of internet name resolution, yet historically it has been vulnerable to a range of security attacks such as DNS spoofing and cache poisoning. As cyber threats become increasingly sophisticated, organizations must prioritize security for their DNS...

Networks worldwide are facing an advanced and resilient form of cyberattack that leverages a sophisticated DNS-based evasion technique known as “fast flux.” Despite constant advancements in cybersecurity tools and awareness, fast flux remains an often underappreciated Achilles’ heel by which...

Here is a summary of the CISA alert about Fast Flux as a national security threat: CISA, together with the NSA, FBI, ASD’s ACSC (Australia), CCCS (Canada), and NCSC-NZ (New Zealand), released a joint Cybersecurity Advisory warning about the ongoing threat of fast flux-enabled malicious...

Fast flux attacks are no idle chatter in the cybersecurity world—they’re a rapidly evolving tactic that can leave even the most fortified networks scrambling. Recently, the U.S. Cybersecurity Infrastructure Agency (CISA) joined forces with international partners from Australia, Canada, and New...

We can hardly believe it’s been about one year since we launched the new Microsoft Edge – and what a year it’s been! It’s safe to say that a lot has changed since our launch in January 2020, but one thing that remains constant is our commitment to our users. We’re all more dependent on the web...

October is almost over! The leaves are changing, pumpkin spices are everywhere, and frights and haunts are becoming commonplace. In the U.S., it’s also National Cyber Security Awareness month. To celebrate it all, we’ll share some of the great security and privacy features that we’ve added to...

Hi Everyone, In our environment, we run Vulnerability to scan in the servers using the Nessus scanner tool, as a result it throws some Vulnerability issues as listed below: SMB Signing not required DNS Server Cache Snooping Remote Information Disclosure SSL DROWN Attack Vulnerability...
