For many with an IT Operations background we know Syslog event messaging as a highly useful logging function. It is ubiquitous in Cisco hardware products and controllers, and most management software; it’s also prevalent in other IT. Syslog is used to inform about operational state, component failure, security incidences, and other informational items. Our Cisco DNA Center and Cisco Secure Network Analytics (formerly Stealthwatch), along with common solutions like Splunk and Elasticsearch, receive syslog event…

Progressing towards net zero is important, but none of us can deliver a sustainable future alone. My conversations over recent weeks with customers, partners and Cisco teams across the region have demonstrated very clearly to me that the urgency of taking action on climate change is now top of mind. A topic that was too often contained to a company’s CSR report only a few years ago has become a business imperative today, with net…

A conversation with Shawnee Heights School District   You have likely heard us talking more about security resilience in recent weeks. Resilience has always been a key part of cybersecurity, but the last few years have really highlighted its importance.   At Cisco, we define security resilience as: The ability to protect the integrity of every aspect of your business to withstand unpredictable threats or changes, and then emerge stronger. Depending on the business, this will look…

Coming into 2022 everyone is feeling the business climate change toward the positive. While the “Great Resignation” may be felt in some industries and many may be contemplating new career paths, the need for global IT professionals has been strong, even in the years before the pandemic. For many years, Cisco has been successful with the Networking Academy program. They help to transform many learners in urban and remote areas, through the power of technology,…

The pandemic accelerated digital transformations for enterprises across the globe. With the flip of a switch, IT workers transitioned to a remote work environment. We took meetings from our kitchens, we learned that it’s not the end of the world when a child or pet crashes a meeting, and some of us rekindled our relationship with sweatpants. It wasn’t without its challenges, but it was still a relatively smooth transition for IT workers. This wasn’t…

“The evolution of policy management must include applicationsand their supporting frameworks such as Kuberneteswith public cloud, microservices, and APIs.” As a driver we often take for granted our driver’s license – unless you’re one of my twin 16-year-old daughters! 😊In states and countries with reciprocal agreements driver’s licenses allow the authority to use public motorways and define privilege levels or endorsements, such as private automobile, motorcycle, commercial truck, etc. Imagine a world where this authorization…

A storage area network (SAN) is a dedicated, high-speed network that provides access to block-level storage. SANs were adopted to improve application availability and performance by segregating storage traffic from the rest of the LAN.  SANs enable enterprises to more easily allocate and manage storage resources, achieving better efficiency. “Instead of having isolated storage capacities across different servers, you can share a pool of capacity across a bunch of different workloads and carve it up…

When I was growing up, Earth Day was always one of those annual events on the school calendar that generally would fly by without much attention. Occasionally we’d have a teacher who would discuss the evils of pollution and its effect on the ozone layer. Then, if we were lucky, we’d go outside with the entire class and plant a tree. But, for the most part, Earth Day didn’t garner the visibility of other more…

A few years ago, I was tasked with solving a problem at work: I had to figure out how to stay in compliance with a National Credit Union Administration (NCUA) audit requirement for properly tracking and logging security vulnerabilities in our technology and applications. We had only a rough collection of functions in our software and network management tools that could do this, and those didn’t satisfy the auditors. With the handful of software tools…
