Good morning, everyone!
This week’s critical vulnerabilities:
Patch All the Things! |
If you don't need it, get rid of it!
This is a standard security practice, included in most security standards I've ever read, and yet few people or organizations actually follow this practice. Let's talk about what this is, and why it's important.
You can't secure it if you don't know it's there. If your employees (or family members) have local administrative privileges on their computers, they can install software (and malware, but that's a topic for another time). There are two reasons this could be problematic:
1. Missing updates Remember that LastPass Breach ? More recent information has indicated that the bad guys took advantage of a vulnerability in Plex, a streaming app, installed on the senior engineer's computer. Having auto-update turned on for Windows and MacOS is not going to auto-update third-party applications on your computer (and even the endpoint management tool on your network can't update software it doesn't know about). You need to keep a software inventory, check periodically to make sure everything is up to date, and remove unnecessary software. (If you need a refresher, read How do I Patch my Things?)
2. Pre-installed malware A few years ago, Lenovo was hit with a massive class-action lawsuit regarding the use of software from Superfish, an ad company whose programs endangered sensitive data, in its laptops. This is just one example of the many potentially unwanted software applications that may be installed on work or personal devices. They may seem innocuous, and may not be inherently bad, but they can provide backdoors to your network and to your data.
So, go take inventory and determine what software you need to keep. Have a good week!
