“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 security architectural transformation.
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. Hardening includes, but is not limited to: Block unused ports on servers and firewalls. For more information, see How to Prevent DNS Attacks.
These developments have made the perimeter so porous that the old approach of simply hiding behind a firewall and keeping the rest of the world at bay is no longer feasible. So why aren’t more organizations taking advantage of protective DNS? So where do we go from here? The issue likely comes down to awareness.
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.
The shell script downloads several Mirai binaries that were compiled for different architectures, then it executes these binaries one by one. “The attacks are still ongoing at the time of this writing. “The IoT realm remains an easily accessible target for attackers.
The only simple (yet effective) tactic it uses is to brute force its way to gain root access to various Linux architectures. XorDDoS, in particular, has been used to compromise devices using Secure Shell (SSH) brute force attacks. XorDDoS is as sophisticated as it gets. If you plan to get an IoT device soon, buy from a well-known brand.
Limitations of traditional security measures While organizations typically rely on email filters, firewalls, and antivirus software, these solutions often fall short against AI-powered phishing attacks. Zero Trust Architecture: Adopt a Zero Trust approach that verifies every access request, regardless of its origin.
In addition, most DDoS mitigation solution providers bundle Web Application Firewall functionality to prevent DDoS attacks at the application layer. Edge DNS is a DNS service that moves DNS resolution from on premises or data centers to the Akamai Intelligent Edge. Protects websites, networks, DNS and individual IPs.
The campaign was uncovered by CrowdStrike by investigating a series of security incidents in multiple countries, the security firm added that the threat actors show an in-depth knowledge of telecommunications network architectures. ” reads the report published by Crowdstrike.

When the internet arrived, the network added a firewall to protect networks and users as they connected to the world wide web. Technical controls may be implemented by: Hardware appliances : switches, routers, firewalls, etc. In a complex, modern network, this assumption falls apart.
Companies transitioning to the cloud have to think of cybersecurity as more than firewalls, access controls and incident response, and define goals of security that go beyond confidentiality, integrity and availability, said Randy Vickers, chief information security officer for the U.S. Sean Gallup/Getty Images). Technical review.
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. When protection fails, it could be a firewall rule that can be any type of protection. Well, they were doing this for a reason. .
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. Express Micro-Tunnels have built-in failover and don’t require DNS resolution. DH2i Differentiators. Unisys Stealth.
Architecture: Identifies network resources and connectivity requirements for agents. InsightIDR comes with several dashboard views that give administrators visibility into network activity like firewall traffic, blocked traffic by port and IP, total DNS traffic, and DNS queries. Rapid7 Competitors.
