Day 6- Port Security 🗝️ One simple misconfigured port can let an unauthorized device into your network. That’s where Port Security comes in: ✅ Limit the number of MAC addresses per port ✅ Define trusted devices using sticky MAC ✅ Choose violation actions → Protect / Restrict / Shutdown Real-world use case: • A user plugs in a mini switch under their desk → suddenly multiple devices start consuming IPs. With Port Security, that port gets shut down instantly. 🚫 🔑 It’s a lightweight but powerful defense at the edge. #Networking #Layer2 #PortSecurity #Cisco

🛜 Pixie Dust Wi-Fi Attack Exploits Routers' WPS to Obtain PIN & Connect to Wifi Network | Read more: https://lnkd.in/dVpRtzJq The newly publicized Pixie Dust attack has once again exposed the critical vulnerabilities inherent in the Wi-Fi Protected Setup (WPS) protocol, enabling attackers to extract the router’s WPS PIN offline and seamlessly join the wireless network. By targeting weak randomization in the registrar’s nonces, this exploit subverts the intended security of WPS without requiring proximity or sophisticated hardware. WPS was designed to simplify Wi-Fi setup by allowing devices to join a network using a short 8-digit PIN rather than the full WPA2-PSK. #cybersecuritynews

https://lnkd.in/g778rTtF Raising Awareness on Pixie Dust Wi-Fi Attack 🔒 Wi-Fi Security Alert: Pixie Dust Attack on WPS Did you know that a critical flaw in Wi-Fi Protected Setup (WPS) can expose your network to the Pixie Dust attack? This vulnerability allows attackers to recover the 8-digit WPS PIN offline and gain unauthorized access to your Wi-Fi—sometimes within seconds. What can you do? Disable WPS entirely on all routers, not just in the UI but in firmware (where possible). Always update router firmware to the latest version. Advocate for secure defaults and better transparency from vendors. Stay informed and regularly audit home and office Wi-Fi infrastructure for legacy risks.

Pixie Dust Attack: Why WPS Is a Weak Link in Wi-Fi Security The Pixie Dust attack shows how WPS (Wi-Fi Protected Setup) can be exploited to steal PINs and gain network access. It’s a reminder that convenience often comes at the cost of security. Disable WPS when possible and rely on strong WPA2/WPA3 passphrases to protect your network.

A massive surge in scans targeting Cisco Adaptive Security Appliance (ASA) devices was observed by GreyNoise in late August 2025, with over 25,000 unique IPs probing ASA login portals in a single burst. This anomalous activity is a sharp deviation from the usual baseline of <500 per day, and may indicate that attackers are probing these devices in preparation for future attacks. Here’s what to know about evolving attacker tactics, the current state of Cisco ASA lifecycle support, and how Eclypsium can empower network defenders through specialized device security features to protect Cisco ASA devices: https://hubs.ly/Q03JD4Lj0 #VulnerabilityAlert #CiscoASA #GreyNoise #SupplyChainSecurity #Eclypsium

How often do you update the firmware on your home wifi router? Not too often, maybe that is okay...for you. But, it turns out this is kind of a big deal for enterprise companies. Here is why: Old firmware running on network devices, (like Cisco routers), often have exploits. Exploits are ways to get into the device over the internet. An attacker, (who could be on the other side of the planet or eating some Chipotle in a basement nearby), can then use the access to steal valuable intellectual property or corporate secrets (such as that slackmoji you should never have added but now can not delete for some reason!). Ye' olde router firmware also often has been **knowingly exploited** which means there is proof that someone out there is actively using the bugs in the firmware to get in and do bad stuff. This article goes into a little bit of detail on the matter, how to defend against this on Cisco Adaptive Security Appliances (ASA), and how Eclypsium, Inc. monitors, detects and remediates when a vulnerable device is found on an enterprise company's network.

Still thinking about #SDWAN like it’s a static network device? Routers and firewalls may stay the same for years — but SD-WAN platforms are constantly evolving, with major updates and new capabilities rolled out multiple times a year. And yet, many enterprises remain stuck in a version 1.0 mindset. To unlock the full potential of SD-WAN 3.0, businesses need to rethink earlier design decisions and work with partners who understand where the platform is headed. 👉 Discover how reassessing your SD-WAN with the right partner can drive better outcomes: https://okt.to/72yZF8 #TataCommunications #NetworkFabric #DigitalFabric #Network

IP Conflicts | This Might Not Sound Interesting Enough.. But! Should be taken quite seriously! There's something known as Conflicting IP Addresses Which Usually happens when two or more devices on the same network are assigned the same IP address. Since an IP address must be unique, the network can’t tell which device to communicate with — leading to connection issues, dropped services, or total network failure for those devices. Recall In Cybersecurity One Of Our Concerns Is Making Sure Information Is Available right? Exactly! IP Conflicts goes against information availability. Like An Incidence Response there's a way you to tackle It. First we would have to find The Mac addresses of these devices sharing the same IP. By, >> Checking DHCP logs for duplicate IP events( Steps are usually different for the various OS) >> Ping & use arp -a to see which MAC replies >> Scan network with tools (e.g., Angry IP Scanner) >> Check switch ports to find where devices are connected >> Proceed to use wireshark if conflict seems hard to trace. If You've Successfully Found The Devices These Are The Quick Fixes! • Change one device’s IP or set to #DHCP( Dynamic host configuration protocol) • Adjust DHCP pool to avoid overlaps • Keep a record of static IPs. Then That's Pretty Much It!!! #Thinksecurity
