5 Cyber Resilience Lessons We Re-Learned in 2021 (But Will Probably Forget)

And some others assistance IT groups fix some aged problems, but build new types. But calendar year in and calendar year out, very good fundamentals under no circumstances go out of design and style.

2021 was no different. Here’s a look back again at some of the year’s most devastating assaults, outages and cyber resilience failures, and the lessons we ought to find out from them (but probably would not).

Beware of Misconfigurations. (And Phase Your Networks, Please.)

December 7 a notably terrible outage disrupted broad swaths of the web for far more than seven several hours. It influenced EC2 and other AWS solutions, which triggered disruptions and downtime for significant AWS customers – like Netflix and Disney In addition – as very well as Amazon’s individual solutions, like Alexa, Ring, and its package delivery administration. As Sid Nag, vice president of cloud solutions and systems investigation for Gartner, advised InformationWeek’s JP Ruth: “This was one particular of the largest because AWS begun conducting small business.”

The incidents raise questions about the dependability and resilience of the cloud and how to hold AWS and other significant tech companies accountable for sustaining their infrastructure.

Patching Software program is Tricky. Make it Easier.

The complexities in the IT source chain continue on to make application patching far more challenging. Protection professionals’ 2020 holiday break period, and a great deal of 2021, was ruined by malicious stability updates unknowingly administered by Solarwinds. A calendar year later on, an additional holiday break ruined, this time with a vulnerability in extensively utilized third-get together code.

Insurance policies Can’t Save You from Ransomware Attacks.

The ransomware assault on Colonial Pipeline in May confirmed that businesses’ hazard assessments may perhaps lead them to come to a decision to swallow their pleasure and pay a ransom. It also confirmed that, when pressed, people today will pour gasoline into plastic searching bags and that cyber insurers are fed up with keeping the bag for multimillion-greenback ransom payments. As Richard Pallardy wrote for InformationWeek in October, “cyber criminals have taken take note of cyber insurance plan alone as a opportunity revenue resource, occasionally penetrating insurers in search of their consumer lists — a prosperous resource of targets. This liability is, of class, handed along to the consumer.”
