Several Cisco-manufactured network equipments have been found vulnerable to five new security vulnerabilities that could allow hackers to take complete control over them, and subsequently, over the enterprise networks they power. Four of the five high-severity bugs are remote code execution issues affecting Cisco routers, switches, and IP cameras, whereas the fifth vulnerability is a denial-of-service issue affecting Cisco IP phones. Collectively dubbed ' CDPwn ,' the reported vulnerabilities reside in the various implementations of the Cisco Discovery Protocol (CDP) that comes enabled by default on virtually all Cisco devices and can not be turned OFF. Cisco Discovery Protocol (CDP) is an administrative protocol that works at Layer 2 of the Internet Protocol (IP) stack. The protocol has been designed to let devices discover information about other locally attached Cisco equipment in the same network. According to a report Armis research team shared with The Hacker N...

With the migration of governments and enterprises towards controller-based architectures, the role of a core network engineer has become more important than ever. Today, majority of interconnected wide area networks (WANs) and local area networks (LANs) in the world run on Cisco routers and other Cisco networking equipment, and therefore most organizations need network engineers to maintain and program these networks. So, if you are looking forward to making career advancement in networking, then Cisco's CCNA and CCNP certifications are one of the most highly reputed entry-level networking certifications in the industry. While CCNA, or Cisco Certified Network Associate, is for entry-level network engineers to maximize their foundational networking knowledge, CCNP or Cisco Certified Network Professional is intended for professionals to implement, maintain and plan Cisco's wide range of high-end network solution products. But how long have you wanted to take CCNA and ...

As SaaS providers race to integrate AI into their product offerings to stay competitive and relevant, a new challenge has emerged in the world of AI: shadow AI.  Shadow AI refers to the unauthorized use of AI tools and copilots at organizations. For example, a developer using ChatGPT to assist with writing code, a salesperson downloading an AI-powered meeting transcription tool, or a customer support person using Agentic AI to automate tasks – without going through the proper channels. When these tools are used without IT or the Security team's knowledge, they often lack sufficient security controls, putting company data at risk. Shadow AI Detection Challenges Because shadow AI tools often embed themselves in approved business applications via AI assistants, copilots, and agents they are even more tricky to discover than traditional shadow IT. While traditional shadow apps can be identified through network monitoring methodologies that scan for unauthorized connections based on...

Cisco, a networking giant that offers traditional network edge protection, has announced that the company is buying cloud-based security company OpenDNS for $635 Million . Yes, OpenDNS , whose Domain Name Services (DNS) you might have used to avoid regional restrictions or to improve your Internet connection. However, Cisco is not making the acquisition of OpenDNS for any of the above reasons. Instead, the networking giant says it will boost its own cloud security, adding "broad visibility and threat intelligence from the OpenDNS cloud-delivered platform." The aim is to offer you the protection against cyber attacks on your corporate network from any device, anywhere, anytime, and to predict threats before they strike. Hilton Romanski , who leads business development at Cisco, wrote in his blog post : "The acquisition will extend our ability to provide customers enhanced visibility and threat protection for unmonitored and potentially unsecure entry...
