Network security architecture is a strategy that provides formal processes to design robust and secure networks. This article explores network security architecture components, goals, best practices, frameworks, implementation, and benefits as well as where you can learn more about network security architecture.
Wired is reporting on a new remote-access Trojan that is able to infect at least eighty different targets: So far, researchers from Lumen Technologies’ Black Lotus Labs say they’ve identified at least 80 targets infected by the stealthy malware, including routers made by Cisco, Netgear, Asus, and DrayTek.
A PDNS service uses existing DNS protocols and architecture to analyze DNS queries and mitigate threats. Over a six-month period, the PDNS service examined more than 4 billion DNS queries to and from the participating networks, blocking millions of connections to identified malicious domains.
I was recently at an event listening to representatives of ICANN and CloudFlare speak on security with DNS and it occurred to me that very few of us really understand. The post The Evolving World of DNS Security appeared first on PerezBox.
DMZ networks typically contain external-facing resources such as DNS, email, proxy and web servers. DMZ networks are also helpful for separating out third-party servers, routers, and other technologies and platforms that don’t have as many manageable security features and controls built in.

Cisco Technologies.
Today SOC teams use many different technologies to detect threats. Many large customers have 30 or more security technologies in their defense in depth architecture. Every one of those technologies generate their own specific ALERTS. That is simply not the case, and we need a new way to describe and track these events.
DCAP can be seen as an intelligent security instrument that provides off-the-shelf data protection technologies, implementing a new approach to solving an important and necessary task. DCAP also covers your network: proxy servers, VPN and DNS, cloud solutions like Microsoft 365 and G Suite, as well as various third-party applications.
Amid discussions on the security of open source technologies like eBPF and Hadoop, OpenSSF speakers Jennifer Fernick, SVP and head of global research at NCC Group, and Christopher Robinson, Intel’s director of security communications, outlined the group’s vision to secure open source software “end to end, at massive scale.”
During an incident response performed by Kaspersky’s Global Emergency Response Team ( GERT ) and GReAT, we uncovered a novel multiplatform threat named “NKAbuse” The malware utilizes NKN technology for data exchange between peers, functioning as a potent implant, and equipped with both flooder and backdoor capabilities.
For example, the 2016 DDoS attack on the Dyn managed domain name service (DNS) caused the DNS service to fail to respond to legitimate DNS inquiries and effectively shut down major sites such as PayPal, Spotify, Twitter, Yelp, and many others. Also read: How to Secure DNS. Types of DDoS Attacks. Harden infrastructure.

Rapid7 Competitors.
The emergence of SD-WAN and SASE technologies bundled together has led many vendors to address both advanced routing and network security vendors for clients. The youngest secure SD-WAN pick is SASE technology vendor Cato Networks. Networking specialists like Cisco and HPE’s Aruba are moving deeper into security. Cato Networks.
25+ Years of Black Hat (and some DNS stats), by Alejo Calaoagan. Cisco is a Premium Partner of the Black Hat NOC , and is the Official Wired & Wireless Network Equipment, Mobile Device Management, DNS (Domain Name Service) and Malware Analysis Provider of Black Hat. Umbrella DNS into NetWitness SIEM and Palo Alto Firewall .
Just what is SASE technology? Specific technologies found in SASE offerings often include SD-WAN and Cloud Access Security Brokers (CASB) , secure web gateways , ZTNA, firewalls as a service (FWaaS) , VPNs and microsegmentation. What is Secure Access Service Edge? ResearchAndMarkets sees the SASE market growing at a 36.4%
Jeremy Brown helped Trinity Cyber develop counter maneuvers for a DNS exploit requiring deep parsing of a certain kind of traffic, deploying it to all clients in less than two days. They developed a powerful new approach to intrusion prevention system as-a-service, delivered through a service edge architecture and patent-pending technology.
It seems that no matter how many security technologies, network perimeters, and intrusion prevention safeguards are erected, the bad guys somehow find a means of entry. It uses Express Micro-Tunnel technology for discreet and private connectivity between distributed environments. DH2i Differentiators. Unisys Stealth.
Director of Information Security, State of Colorado Governor's Office of Information Technology; and Toby Zimmerer, Sr. How effective will these proposed technology solutions be against quantum computing, and what are the potential challenges with adopting these new cryptographic solutions and algorithms? Is it a business problem?

Depending on the company’s VPN architecture, this can be done through a cloud provider by increasing seats, adding licenses to the existing VPN hardware solution, or purchasing and deploying new VPN servers. To accommodate this increased demand, organizations can optimize VPN server use by using traffic steering at the DNS layer.
Between the DNS attacks and ongoing ransomware scourge, it’s beyond time for providers to seek more creative responses to cyber challenges even with limited budgets, in combination with participation in threat-sharing programs and while relying on free or low-cost resources.

SASE vendors provide points of presence (PoPs) worldwide using the cloud or SD-WAN technology. What Are the SASE Benefits?
50,000 DDoS attacks on public domain name service (DNS) resolvers. 553% increase in DNS Flood attacks from 1H 2020 to 2H 2023. DDoS attacks on single networks or websites render them unavailable, but DDoS attacks on DNS resolvers bring down all networks and websites using that DNS resource.
This architectural approach is a hallmark of APT malware. DNS resolutions for pool servers are cleverly concealed behind DNS over HTTPS requests to the Cloudflare DoH (DNS over HTTPS) service , adding an extra layer of stealth to its operations.
Furthermore, our seamless integration with leading security components such as Microsoft Defender for Endpoint and other EDR/XDR solutions ensures a cohesive defense architecture that maximizes efficacy, minimizes response times, and allows for unparalleled deployment flexibility and configuration.

These physical controls do not rely upon IT technology and will be assumed to be in place.
Protecting your organization from these and other forms of cyber threats are precisely why you get up in the morning, it’s why you vie for budget, search for qualified staff, and evaluate and purchase technology to accomplish your cybersecurity mission. Not if we can help it!
Attack surface management (ASM) is a relatively new cybersecurity technology that combines elements of vulnerability management and asset discovery with the automation capabilities of breach and attack simulation (BAS) and applies them to an organization’s entire IT environment, from networks to the cloud.
A visitor photographs a symbol of a cloud at the Deutsche Telekom stand the day before the CeBIT technology trade fair. Whenever a company establishes a connection to a CSP, it has to consider whether to change its architecture. Sean Gallup/Getty Images). Technical review. Some CSPs have dedicated links.
And they didn’t even give it a DNS look up until almost a year later. The majority of this tactic took place from a C2 perspective through the partial exfiltration being done using DNS. They knew they were going after a very specific vendor. But the code application 2019 was weaponization in 2020.
Once the victim has started the program, it changes the DNS settings on the device so that all domains are resolved through the attackers’ servers: this prevents the victim from accessing certain antivirus sites. The sample extracts a URL from the “downloadURL” field for the next download.
Just in the last two years, many such simple and avoidable mistakes in securing the application and data hosted in the public cloud have led to massive data and network breaches at large financial and technology firms such as Accenture, Booz Allen Hamilton, Capital One, Facebook, MGM, Microsoft, and Verizon.
And I do need to give a special shout-out to World Wide Technology who does have people openly talking about this topic. There are many ways to achieve cyber resilience – one of them is through the deployment of Protective DNS.
