What SMBs can do to protect against Log4Shell attacks

2021-12-15 21:01

As you may already know, the business, tech, and cybersecurity industries have been buzzing about Log4Shell (CVE-2021-44228), aka Logjam, the latest software flaw in an earlier version of the Apache Log4j logging utility. As the name suggests, a logger is a piece of software that logs every event that happens in a computer system. The records it produces are useful for IT and security folks to trace errors or check any abnormal behavior within a system.

Understandably, this may be the first time you’ve been told explicitly about the Log4j tool, but what many don’t realize is that hundreds of millions of applications and web services, including those offered by Twitter, Apple, Google, Amazon, Steam, and Microsoft, among others, rely on it. The software and online services you use in your business may be Java-based, too, thus opening you up for possible exploitation.

Exploiting this flaw allows hackers to worm their way into unpatched systems to take control. It’s seriously bad to have this on any endpoint because of its ultra-wide attack surface and the accompanying damage potential that could bring.
