Further Contributor: Pradnya Padaki

Stepping right into a Safety Operations Centre (SOC) at Cisco Reside Melbourne for the primary time was an expertise charged with pleasure and barely nervous. Beforehand, my solely understanding of SOCs got here from listening to buyer tales and dealing with their challenges—I had recognized the strain, urgency, and teamwork required solely by way of their eyes, by no means having been in these footwear myself.

Opposite to my expectations of a drawn-out onboarding, the method was surprisingly swift (taking lower than 10-20 minutes). Due to Duo, I used to be shortly given entry to all of the important instruments: Cisco XDR, Splunk, firewall dashboards, and extra from the duo listing. This seamless entry calmed my nerves and made me really feel immediately welcome.

After that, it was all about getting comfy with the instruments and escalation processes. As a Tier 1/Tier 2 analyst, my every day routine revolved round Cisco XDR, which introduced collectively incident alerts from each nook of the community. Every alert got here full of context and intelligence, making investigations a lot much less overwhelming.

Considered one of my highlights was utilizing Endace for the primary time. This instrument gave me the power to dive into packet-level particulars, filter knowledge quickly, and transition from high-level incidents to granular packet captures. Correlating metadata and community flows grew to become simple and even gratifying, serving to me remedy issues with way more confidence.

Through the occasion, I used to be often placed on the spot to share my firsthand expertise of working in a SOC for the primary time, significantly reflecting on my day two investigations. This inspired me to look at fastidiously and suppose deeply in regards to the operational realities. Many purchasers confirmed eager curiosity, recognizing that my expertise may quickly mirror their very own, which made these interactions particularly priceless and motivating.

The primary day was all about orientation: understanding the workflow, attending to know the instruments, and growing the mindset wanted for efficient investigations. With assist from skilled colleagues, I realized to triage incidents, test risk intel, dive into logs, and seek the advice of with the crew earlier than making choices. By the day’s finish, my preliminary nervousness had remodeled into pleasure.

On day two, I took on incidents independently, performing full triage and drafting escalation reviews myself.

Background: Throughout my preliminary SOC project, an alert was generated by Cisco XDR highlighting that an inner endpoint was making connections to a number of IP addresses recognized for malicious exercise.

Detection: Cisco XDR flagged the suspicious habits, visualizing the connections between one inner asset and a number of other high-risk exterior hosts. This raised fast issues about potential malware or command-and-control exercise (see Cisco XDR investigation beneath).

Investigation: To validate and additional analyze the incident, I used Endace for in-depth packet inspection. Filtering for the precise IP and utility revealed a constant stream of visitors matching file switch patterns. Additional evaluation confirmed that the visitors was generated by a BitTorrent utility working on the endpoint (see Endace screenshot beneath).

Response motion: From the primary alert in Cisco XDR, I carried out a complete investigation to shortly confirm the violation of insurance policies. As a Tier 2 analyst, my response included correlating knowledge from a number of sources, conducting packet captures with Endace to rule out malware, and assessing the broader impression on the setting.  As soon as the investigation confirmed Bittorrent utilization because the supply of suspicious visitors, the case was formally escalated to make sure applicable follow-up, together with person schooling and enhanced community controls to mitigate recurrence. The affected endpoint was flagged for additional monitoring, and the appliance was disabled to stop ongoing peer-to-peer file sharing. An in depth incident report was compiled, outlining dangers similar to malware publicity, bandwidth consumption, and privateness vulnerabilities related to unauthorized Bittorrent exercise.

End result & Reflection: Seeing the investigation by way of preliminary alert to root trigger willpower—leveraging each Cisco XDR and Endace—marked a serious milestone in my SOC journey. This end-to-end incident dealing with not solely bolstered procedural self-discipline however considerably boosted my confidence in dealing with real-world threats.

By the tip of the occasion, I noticed the true essence of a SOC isn’t nearly instruments or dashboards. It’s about individuals: collaboration, belief, shared curiosity, and supporting one another. At the same time as a newcomer, I used to be welcomed, trusted, and inspired—which made a world of distinction.

In abstract, my first SOC expertise turned preliminary nerves into real confidence. I entered as an observer and left feeling like a part of the crew—a journey outlined by assist, studying, and the fun of fixing real-world safety challenges.
