The article explores the potential threats and ransomware issues which endanger the Data on SQL Server and provides a safety guide to overcome such threats.
One of the biggest problems enterprises face these days is ransomware and the practical consequences of ransomware are severe. It is important to be conscious of such threats to maintain the security of the database and protect critical data of your organization from such malicious programs. One should implement a careful strategy to analyze the potential threats and server attacks and utilize the procedure to secure the system.
Here are a few handy tips which you can use to secure your system and reduce exposure to these programs and threats.
1. Using Antivirus
The most common technique to fight ransomware is to use Antivirus programs. Yes, Antivirus software doesn’t enjoy a great reputation when it comes to server security as they hamper performance and cause network errors but here we are talking about potential risks.
A good Antivirus program can protect your data against common threats and should be actively used but it’s not full-proof security check. Some of the greatest malware are designed in a way to bypass the anti-virus security but it’s still a better option than having no security system. As a precaution, do keep a corrupt mdf recovery tool nearby.
2. Privileged Access and Accounts separation
Most of the ransomware cases occur because of unauthorized access to unprivileged users. You should separate accounts for day to day activities and SQL Server-usage to restrict ransomware attackers to use your data against the database on SQL Server.
Microsoft has emphasized on Privileged access Workstations which focuses on using a separate set of Workstations. Majority of vectors including Email are blocked on privileged-access workstations to prevent ransomware’s entry into the system.
3. Ensuring that Servers are patched fully
Malware often attacks vulnerable users who install suspicious software and program unconsciously or permits uncontrolled operations that run in the background. That’s why it is advised to keep servers up to date on patching to avoid providing an advantage to malware threats. Limited authorized access to users can also help in this issue up to a great extent.
4. Block Direct Access
Ransomware requires standard access for encryption process so it’s advised to block accessing shares. It is also true that users need only SQL server listening ports for access. By reducing share access from workstations, you can protect your SQL servers from potential threats and infections on workstations which are usually the source.
5. Disable all unnecessary protocols and services
You should disable all the protocols and services which are vulnerable to potential ransomware attack. This will reduce the surface area and exposure to threats. It usually happens that users unknowingly install many components which are not actually required in SQL server or OS. These are usually the targets of ransomware so users should be careful before availing any service or component.
6. White listing Internet Outbound Traffic
Most of the ransomware attacking the server require communications from the server through internet. That’s why it’s necessary to block all outbound connections from SQL servers which can restrict the required communication. It restricts the ransomware encryption and protects the servers.
