The network can be host to multiple performance killers. Here are three worth noting
Like Ed Sheeran as a secret stormtrooper in “Star Wars: The Rise of Skywalker,” some cameos are hard to spot. They can appear out of nowhere halfway through the film or remain a complete mystery until behind-the-scenes footage reveals the masked actor.
The same can be said for guest appearances on your network. It’s tough to spot the hidden malware, application interactions, network delays and other “cameos” popping up, especially when organizations today are grappling with the complexities of public, private and hybrid cloud infrastructure and multi-tier applications. To adequately support a robust and secure digital infrastructure, you need network and application-layer visibility.
With movie awards season upon us, I invite you to sit back, relax—pop some champagne, if you’d like—and I’ll tell you about three cameos that can be easy to miss in the network environment, and what you should do about them.
Hidden Malware
At a pivotal moment in the Oscar-nominated “Joker,” the evil protagonist studies a tape to prepare for his appearance on a popular TV show. On the tape, he sees a comedian appear on the same show—played by Justin Theroux. It’s a blink-and-you’ll-miss-it cameo from Theroux, very much like hidden malware traversing the network without detection.
Whether they’re sophisticated or non-targeted, high-volume criminally motivated attacks can move throughout the network without your knowledge and cause enterprises significant damage and cost, to the tune of $6 billion by 2021. Emotet, described by the Department of Homeland Security as one of the most costly and destructive instances of malware, likely comes to mind as one of the most pertinent examples. It has the ability to move laterally through the organization, spread other damaging malware and constantly evolve.
Spotting hidden malware requires network visibility that spans the entire distributed digital infrastructure, as well as having access to network data to ensure visibility for all security and performance tools. Specifically, organizations need reliable access to data in motion to tap into traffic across cloud and on-premise infrastructure and traffic flowing across 5G and 100GB networks. This type of pervasive visibility allows enterprises to keep up with the speed at which networks and businesses run, as well as with security demands.
Interactions Between Applications or Microservices
When Brad Pitt’s character in “Once Upon a Time in Hollywood” unknowingly ends up at the Manson Family compound, he comes across Dakota Fanning, who plays a key member of the infamous cult. Their meeting is short but meaningful, and sets the stage for additional character development and exchanges down the line. Interactions between applications or microservices are just as meaningful, with 80% of network traffic consisting of such communication on average.
Understanding these interactions is critical for guiding digital transformation (DX) efforts, which are a top priority for 87% of business leaders. Among the goals of DX are streamlining business processes, cutting costs, improving productivity and introducing new business models that redefine industries—or build new ones. These are ambitious goals, and they’re ultimately realized through new digital applications built on intricate microservices-based architectures that need to be managed and secured.
Only with a clear view, and the right kind of data, can you understand the applications’ interactions, performance and security characteristics to accelerate DX. And the only way to get to this view is to look at the data in motion on the network. The ability to isolate specific applications or microservices communication streams for deeper inspection allows infosec teams to easily understand access patterns and put in place effective micro-segmentation strategies. Application developers, too, can benefit from this by better understanding communication bottlenecks between applications and microservices, as well as troubleshoot them.
Traffic Bottlenecks
The latest rendition of “Little Women” follows a non-linear storytelling structure, constantly jumping between two timelines. It can be jarring to viewers when the girls’ father returns from war, revealing himself as the actor Bob Odenkirk. While this moment is meant to be an intimate glimpse into a family coming together after a long separation, it brings the movie-watching experience to a standstill, since the audience associates Bob Odenkirk less with a serious scene and more with his previous comedic roles.
Networks today are similarly prone to experiencing abrupt slowdowns or bottlenecks that limit network performance and waste bandwidth. Managing the network to ensure constant availability is a major challenge when data volumes are growing exponentially. It’s estimated that about 1.7MB of new information will be created every second for every human being on the planet this year. This data explosion paired with digital transformation technology investments and lightning-fast 5G and 100GB networks has led to a very complex enterprise infrastructure setup—and network blind spots across physical, virtual and cloud environments.
The solution lies in having the right kind of data to help you understand network and application performance. By analyzing the network traffic, you get immediate actionable data points that can be used to address trouble spots.
Whether we’re talking big screen or enterprise network, surprise cameos are common and they are easy to miss—and this is particularly problematic when things like malware and bottlenecks pose a threat to network security and speed. For the NetOps and infosec pros tasked with complex infrastructure development, implementation, maintenance and security, you need a clear line of sight into what’s happening within the network. Armed with insights on traffic patterns (both cloud and on-premises), delays in data flow and insecure areas, you can use this intel to write the screenplay (or plan) to support a robust and secure digital infrastructure.
