Ah, OAuth 2.0. The protocol that promised to end password reuse and save us from the deep, dark, insecure corners of the web. The one we thought would be the antidote to phishing. But guess what?
Last year I wrote a blog about going passwordless (you can check it out here: https://www.lookingpoint.com/blog/passwordless). Now I’m doubling down and telling you that passwords are outdated. They’re reused, guessed, phished, and stolen. Despite password managers and multi-factor authentication (MFA), the underlying security model of passwords is inherently weak.
Efficient network management is crucial for scaling and securing modern networks. Cisco Catalyst Center (formerly DNA Center) offers powerful tools for automating the deployment of device configurations using templates, composite templates, and Jinja2 scripting. In this guide, we will walk through creating and deploying templates, including interface configurations, NTP, SNMP, ACLs, and more, for...
Sometimes it happens, for some reason, you need to move your VMWare hosts to a new subnet. Let’s talk about what you might want to consider and how to make the process as smooth as possible.
In today’s digital landscape, ensuring the security of your network is more critical than ever. With cyber threats evolving rapidly, organizations must adopt robust security measures to protect their sensitive data and systems. One powerful tool in the cybersecurity arsenal is Nessus, a widely used vulnerability scanner. In this blog, we'll explore what Nessus is, how to effectively use it, and...
In today’s interconnected world, the need for robust cybersecurity measures in industrial environments has never been more critical. With the rise of Industry 4.0 and the integration of IoT devices into manufacturing processes, the Purdue Model provides a structured approach to securing operational technology (OT). In this blog, we’ll explore the Purdue Model, its significance, and how...
OSPF is mostly used between a Core switch and downstream OSPF enabled devices like distribution switches, firewalls, etc. If the downstream device is connected via link aggregation to a Nexus vPC pair and vPC peer-gateway is configured, you will encounter OSPF adjacency flaps. This will not be noticed unless the OSPF adjacencies are monitored or debugged, so most engineers are not even aware that...
You know how to whistle, don’t you? Just put your lips together and blow. Well installing WSL is nearly as easy and can up your efficiency and expand your toolset.
Today we are talking about 802.1X, like authenticating a device coming into a conference room.What is 802.1X ? In simple terms, it is an authentication mechanism that we leverage.
