Issue/Introduction

In the field of cybersecurity, hash algorithms play a crucial role in ensuring data integrity and confidentiality. Among various hash functions available today, one of the most widely used algorithms is the Secure Hash Algorithm 1 (SHA-1). 

The primary vulnerability of SHA-1 is its collision resistance, which means that it is possible to find two different messages that produce the same hash value.  Therefore, it is recommended that SHA-1 be disabled on Security Analytics Dell ME4 storage arrays.

Resolution

1. Log in as a privileged user to the Dell Powervault Manager
2. Click the "Action" button.
3. Select "System Settings"
4. Go to the Services section and uncheck SSH.
   
   
   
   
5. Click "Apply and Close"
