Consequences of Expired Digital Certificate Extend to Tech Titans Microsoft and Cisco

In the rapidly evolving landscape of technology, where digital interactions have become the backbone of modern society, the vulnerability of even the largest tech giants has come to the forefront. Recent incidents involving industry titans like Microsoft and Cisco have highlighted the critical importance of managing digital certificates – the often-overlooked guardians of secure digital communication. These incidents are a stark reminder that no entity, regardless of size or stature, is immune to the far-reaching consequences of expired certificates.

Outages happen more often than we realize.

Many people might not know about digital identity certificates, but they definitely notice when organizations don’t handle them well. When a certificate expires, it stops secure connections. For example, if you try to use your banking website and the certificate is expired, your browser will stop you from accessing the site. You can’t use the service even if the bank’s servers are working.

Recently, some big companies have had problems because of certificate mistakes. Microsoft Teams didn’t work for about three hours in February because of an expired certificate. This affected people who use it for online meetings. Later, Spotify, a music streaming service, had a similar issue. People couldn’t listen to music for an hour. The problem was fixed after someone noticed an important certificate had expired.

These outages were short and not too bad, but that’s not always true. O2, a European mobile company, had an outage that lasted almost a whole day. It turned out that an expired certificate from a company called Ericsson caused the problem. O2 got around $132.8 million as compensation from Ericsson. This wasn’t the first time a big issue happened because of an expired certificate, but it was the one that made people realize how serious it can be, both for money and reputation.

Recently, California had a serious problem. They didn’t report all their COVID-19 cases because a certificate had expired. This messed up their system and caused a backlog. Certificates are super important for website and device security. Not handling them right can cause problems in the real world.

Struggles with Managing Digital Certificates

Taking care of digital certificates is essential to avoid costly problems with your online services. These certificates have a limited time. They’re valid; if you don’t watch them, your applications might stop working. If you miss important details like when a certificate expires or which device it’s connected to, you might not renew it in time, and your online service could go down.

Here are some reasons why digital certificates might not be managed well

  • Limited Visibility

    It’s hard to keep track of all your certificates and their important details, like when they’ll expire or where they are on your network. This makes it tough to know if there’s a problem, fix issues, and stop your apps from crashing or being hacked.

  • Time-Consuming Manual Work

    Doing things manually to handle certificates is slow and can easily lead to mistakes. Setting up certificates manually takes time, making your apps and devices slow. Renewing, revoking, and checking certificates manually can also cause your services to go down or be less secure.

  • Dealing with Many Certificates

    If you have lots of certificates from different places, managing them gets complicated. Some certificates come from inside your organization, and some from outside have different expiration dates. This makes everything harder to manage.

  • Not Ready for Changes

    Doing things manually doesn’t work well when things change. If you need to update your setup or renew many certificates all at once, it takes too much time and planning. This leaves your certificates open to attacks, and your services might be vulnerable for too long. Also, you might not know your certificates’ security standards, making it hard to spot problems and fix them quickly.

  • Cloud Confusion

    With more certificates spread across different cloud services and devices, keeping track of them is tough. Old tools and manual work can’t handle this well so some certificates might get ignored. Attackers can then find these ignored certificates and use them. Keeping track of certificates using spreadsheets across different clouds is risky for your business’s safety.

Impact of Certificates Expiring Unexpectedly

We have papers like driver’s licenses and passports with dates on them. When those dates pass, we can’t use them anymore. Digital certificates are like this for machines. They help machines identify themselves and work safely. But what happens when these certificates expire?

  • Unexpected Shutdowns

    An unexpected shutdown means a system can’t do its main job. This might mean it’s offline or not working properly because of an expired certificate. If certificates aren’t renewed on time, it can lead to the system going down. This happened to Starlink, causing problems for them.

  • Open to Hackers

    Expired certificates that don’t follow security rules become open doors for hackers. Hackers look for these weak points to attack. They can do serious things like stealing data or tricking systems. Many companies use different certificates, and tracking them all is hard. Hackers are taking advantage of this chaos to carry out more complicated attacks.

  • Customers Lose Trust

    When a website has an expired certificate, it shows a warning to users. It might say the site is not secure, or attackers could be trying to steal info. Users will be worried and won’t trust the site anymore, even if there’s still some encryption going on.

  • Harm to Reputation

    A bad reputation might not directly cost money but can hurt a lot. People won’t like it if a website keeps having problems, warnings, and slow internet. This can especially be bad for big customers. They might leave, and that’s a big loss. This bad image can spread to the whole business, making it hard to get support and money.

The Power of Automation in Handling Certificates

Think about all the devices, applications, and services you use. They all have special IDs to work safely. These IDs, called certificates, are like digital IDs for machines. They need to be managed properly to avoid problems. However, doing this manually is hard and doesn’t work well. This is why organizations need to use automation for certificate management.

When certificates expire, it can cause big problems. Imagine if your favourite app suddenly stopped working because of an expired certificate. This can be even worse for important services like Starlink. So, it’s really important to keep track of all your certificates, no matter where they are. This is especially true for cloud services, DevOps (development and operations) setups, and devices like smart devices.

Automating the process of managing certificates means making it easier and safer. It helps find certificates, keeps a list of them, renews them on time, and stops using them when needed. Google even wants certificates to last for a shorter time, so things could worsen if organizations don’t use automation.

The main idea of using automation for certificates is to ensure companies have control and know what’s happening with their certificates. This happens by putting everything in one place and using automation tools to manage certificates from start to finish. This makes sure the process is fast, easy, and secure.

There are important things to do with certificates, like getting new ones, renewing old ones, and stopping ones that are no longer needed. Doing these things right is key to managing certificates well. Automation tools help with this by giving one place to do everything with certificates. This way, you can do things quickly and avoid making mistakes. It’s like having a central control panel for certificates. This also makes it easy to follow the rules for how certificates should be used across all devices and setups.
