I’m sure you know the mantra “If it isn’t broken, then don’t fix it,” and you might argue that this is sound advice. However, complex software systems break in complex ways, often invisible to the casual observer. Luckily, we’re here to help you bring the complexity back down, to something as simple as a banana.
When managing large multi-vendor deployments, keeping track of which level of firmware your infrastructure should be can be a very tricky business, and many businesses adopt the above approach of not maintaining as costs might rise quickly. Don’t get caught unaware of exposed attack vectors made available by not updating dated firmware!
A straightforward way to evaluate any software or firmware is the Banana Metric. Bananas, besides being packed with potassium and other goodness, come with a very interesting feature: their freshness is color coded. I recommend you evaluate your install base in a similar fashion.
### Green
An unripe banana is generally safe to eat, but might cause mild stomach aches in some individuals. Similarly, firmwares that have been very recently released, the bleeding edge, carries similar risks: without extensive field testing, bugs and issues undetected in vendor lab testing will surface in exposure to real-world environments with many vendors and exotic setups.
Green firmwares should really only be used in testing or in preparation for a later rollout in a test lab, if stability is what you want. Of course, new critical features may not want to wait that long, so beware that this release may contain unknown unknowns. When installing Green firmwares, make sure you have a Plan B ready.
### Bright
The bright yellow of a ripe banana signals it’s ready to eat—delicious, nutritious, and generally safe for everyone. In the firmware world, Bright represents the stable release. This is the firmware version that has passed rigorous testing, received vendor and community approval, and been deployed widely without major issues.
Bright firmware is your best bet for production environments where reliability and stability are critical. However, just as bananas can be bruised even when yellow, you should monitor for emerging vulnerabilities or minor bugs that might surface in unique setups. A proactive patching plan ensures your Bright stays brilliant.
### Golden
The golden hue of a banana means it’s at peak sweetness, but also at its most fragile. Golden represents firmware that has been stable for some time, widely trusted, and integrated smoothly into most environments.
While it’s tempting to stick with Golden firmware indefinitely, overripe firmware can quickly turn sour, leaving your systems vulnerable to new exploits. Golden is ideal for organizations that prioritize stability above all else, but remember that no software remains golden forever. Schedule periodic reviews to ensure you’re not clinging to a past prime.
This is the moment to get your Green firmwares in testing!
### Spotty
As bananas age, spots emerge—a sign that they are transitioning. Spotty firmware is past its prime, still functional, but increasingly prone to issues. It might lack patches for newly discovered vulnerabilities, or struggle with compatibility as surrounding systems evolve.
Spotty is a warning sign: it’s time to start planning your migration to a more reliable version. Sticking with Spotty firmware for too long could lead to avoidable headaches, from degraded performance to security breaches. Treat this phase as a critical inflection point to move forward.
### Brown
When a banana turns brown, it’s time to discard—or make banana bread, if you’re resourceful! Brown firmware, however, offers no such reprieve. It is outdated, unsupported, and dangerously insecure. Vendors have likely ceased issuing updates, and your infrastructure is at the mercy of any exploit targeting its vulnerabilities.
Running Brown firmware puts your systems and data at significant risk, and it’s only a matter of time before it fails catastrophically. If you discover Brown firmware in your environment, take immediate action to replace it with a newer version.
This simple color-coded approach ensures you don’t overlook the health of your infrastructure, helping you to balance stability, security, and innovation. After all, nobody wants to deal with a rotten banana—or a broken system.
