Networksecurityarchitecture is a strategy that provides formal processes to design robust and securenetworks. Effective implementation improves data throughput, system reliability, and overall security for any organization.
The domain name system (DNS) is basically a directory of addresses for the internet. Your browser uses DNS to find the IP for a specific service. For example, when you enter esecurityplanet.com, the browser queries a DNS service to reach the matching servers, but it’s also used when you send an email. DNS spoofing or poisoning.

“Features are a nice to have, but at the end of the day, all we care about when it comes to our web and cloud security is architecture.” – said no customer ever. As a result, organizations are coming around to the realization that digital transformation demands a corresponding network and securityarchitectural transformation.
A DMZ network, or a demilitarized zone, is a subnetwork in an enterprise networking environment that contains public-facing resources — such as web servers for company websites — in order to isolate them from an enterprise’s private local area network (LAN).
By increasing visibility into DNS traffic, CISOs can detect, block, and respond to incidents more quickly as well as use this data to institute new controls and increase overall resiliency. So why aren’t more organizations taking advantage of protective DNS? The issue likely comes down to awareness.
The most popular lookup currently being seen in both PoCs and active exploitation is utilizing LDAP; however, other lookups such as RMI and DNS are also viable attack vectors. This was done using the public Docker container , and a client/server architecture leveraging both LDAP and RMI, along with marshalsec to exploit log4j version 2.14.1.
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 SecureDNS. Types of DDoS Attacks.
Deploy Anti-DDoS Architecture : Design resources so that they will be difficult to find or attack effectively or if an attack succeeds, it will not take down the entire organization. DNS servers can be specifically targeted by attackers and vulnerable to various types of attacks. For more information, see How to Prevent DNS Attacks.
The emergence of SD-WAN and SASE technologies bundled together has led many vendors to address both advanced routing and networksecurity vendors for clients. Networking specialists like Cisco and HPE’s Aruba are moving deeper into security. Features: Open Systems Secure SD-WAN and SASE. Palo Alto Networks.
The combination of Prolexic, Edge DNS, and App & API Protector would be recommended for the highest quality of DDoS mitigation to keep applications, data centers, and internet-facing infrastructure (public or private) protected. It is architected for nonstop DNS availability and high performance, even across the largest DDoS attacks.
The basic idea is to segment off parts of the network, especially the most sensitive parts, and wall them off with stricter policies and tie them into a zero-trust architecture. This makes it far more difficult for cybercriminals to move laterally within a network. CloudPassage provides cloud security posture management (CSPM).
SSCP (Systems Security Certified Practitioner). SSCP from (ISC)2 is a mid-level certification designed for IT administrators, managers, directors, and networksecurity professionals responsible for the hands-on operational security of their organization’s critical assets. As of mid-2022, the cost is $381 USD.
Based on Gartner’s forecast, 70% of organizations that implement zero trust network access (ZTNA) between now and 2025 will choose a SASE provider for ZTNA rather than a standalone offering. Support and automation for 5G services is incorporating SASE at the mobile network edge. Key Differentiators.
Networks connect devices to each other so that users can access assets such as applications, data, or even other networks such as the internet. Networksecurity protects and monitors the links and the communications within the network using a combination of hardware, software, and enforced policies.
In this period, agents are installed on network devices, adequately configured, validated, and capable of demonstrating incident detection workflows. Architecture: Identifies network resources and connectivity requirements for agents. Alert Logic AT&T Cybersecurity BeyondTrust Crowdstrike F-Secure Invicti LogRhythm.
FAMOC manage from Techstep, a Gartner-recognized MMS provider, is an MDM designed to give IT a complete view and absolute control over mobile devices used by the workforce, so that people can work more effectively and securely. New Cisco Cloud Security Integrations. New Secure Malware Analytics (Threat Grid) Integrations.
SD-WAN integration with the SASE controller for Meraki, Catalyst, and others Cisco Umbrella SIG unifies firewall, SWG, DNS-layer security, CASB, and threat intelligence functions into a single and well-tested cloud service.
An application gateway, also known as an application level gateway (ALG), functions as a critical firewall proxy for networksecurity. Its filtering capability ensures that only certain network application data is transmitted, which has an impact on the security of protocols including FTP, Telnet, RTSP, and BitTorrent.
DNS Twist is a powerful tool that helps organizations alleviate this problem through analyzing domain names differences. DNS Twist is specialized in generating a comprehensive list of domain names that closely resemble to the given domain. Furthermore, DNS Twist includes fuzzy hashing techniques to estimate webpage similarity.
SASE provides an edge security solution that addresses these challenges without the bottlenecks of traditional virtual private network (VPN) solutions. The single management console provides centralized control and monitoring for the organization and ensures consistent security policies applied throughout the organization.
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.
