Hornetsecurity: Remote Management Survey Results

Hybrid and fully remote employees are officially mainstream and will definitely be a significant part of the employment landscape for the foreseeable future. The cybersecurity experts at Hornetsecurity wanted to learn more about how companies handle security when it comes to remote employees in 2022 and beyond.

To this effect, they conducted a survey among over 900 I.T. professionals from around the world, from various industries and company sizes, to find out more about their approach to remote management.


Here are the survey results highlights:

● 18% of I.T. professionals believe that remote employees are not working securely, and that company data is at risk. 
● According to 3 out of 4 I.T. professionals, employees are using personal devices to access sensitive company data. The majority of these cases are likely to be users accessing emails and documents on their personal mobile phones while using cloud-based systems office applications. 
● 1 in 3 organizations does not provide cybersecurity awareness training to remote employees. Considering that the main counter for the leading causes of cybersecurity issues is user training, the fact that 1 in 3 organizations does not provide said training to remote users is concerning.
● 1 in 6 organizations has suffered a cybersecurity incident directly related to remote working. 

If you want to learn more about the survey’s findings, you can find the full results and breakdown here.

Increase Kasten Catalog Storage

You may notice that Kasten indicated less than 50% on catalog storage. Less than 50% storage will not allow you to perform further Kasten upgrades. 


The first thing that you need to do is add more storage on the worker node & expand it.

If the problem still persists, then you need to increase the default catalog pv size from 20Gi to 40Gi.

Before you do that, you need to check and make sure your storage class allows you to do so.

Command:


kubectl get storageclass <storageclass> -o jsonpath={'.allowVolumeExpansion'}
Note:- take note of the dot inside the { }
The result must be "true"

Next steap
Run a helm upgrade to increase global.persistence.catalog.size to your desired value (example below sets to 40GB):

helm get values k10 --output yaml --namespace=kasten-io > k10_val.yaml && \
   helm upgrade k10 kasten/k10 --namespace=kasten-io -f k10_val.yaml \
   --set global.persistence.catalog.size=40Gi

You storageclass pv has increased to 40Gi

Check SSD Life on Mac

 Each SSD came with TBW life spend. Today we are going to explore on free tool to check your SSD TBW.

To do so,

1. Download smartmoontools from https://www.smartmontools.org/wiki/Download

Click on Install the OSX/Darwin package. Download and install on your mac devices

2. Check which disk using "diskutil list" command. Execute from your Terminal app


My disk is disk0

3. Navigate to tool path

cd /usr/local/sbin

4. Execute command ./smartctl -a /dev/disk0

To identify current TBW (Terabytes written) usage, read

  • Data unit Read
  • Data Unit Written

My result is

  • Data unit Read -34.1 TB
  • Data Unit Written - 13.5 TB
  • Available Spare Threshold: 99%
This unit is M1 Mac Mini with 256GB SSD. TBW is 150 TBW,

Therefore my SSD is still healthy. 

To avoid internal SSD from dying too fast (especially M1 or later model which cannot replace SSD), advise using an external SSD to keep those data that are frequent changes (delete, read, write, etc).

Hope this guide help!

Hornetsecurity recently published their free annual Cyber Security Report for 2023 which takes a deep dive into the current threat landscape, with an emphasis on emerging threats and M365 vulnerabilities which organizations must be aware of in order to protect their operations in 2023. 




Throughout 2022, Hornetsecurity's in-house Security Lab examined over 25 billion emails to provide the most recent insights and statistics on the current threat landscape. Combined with a detailed knowledge of the larger threat landscape, this multinational team of experts leverages Hornetsecurity’s own huge user data set to reveal major trends and predictions for the future of Microsoft 365. 

In 2023, leadership teams will have a lot to think about. Attacks focusing on mobile devices are likely to increase, and so are attack methods targeting MFA (Multi-factor authentication) applications on mobile devices, as threat actors become more sophisticated in their information gathering on targets.

In such a volatile environment, how can you tell which threats to prioritize in 2023?  Stay ahead in the world of cyber security by downloading Hornetsecurity’s free Cyber Security Report 2023!
