While this sounds like a positive change, the survey also found that the pandemic and home working has made security more complex with 3% fewer businesses than last year reporting up-to-date malware protection, 5% fewer deploying security monitoring tools and a whopping 32% of large businesses reporting laptops in use with unsupported versions of Windows. Overall, however, cyber security awareness appears to be up among businesses, with 43% (up from 32% last year) taking out some form of cyber insurance. ## SQL Server Updates: - [CU10 for SQL Server 2019](https://support.microsoft.com/en-us/topic/kb5001090-cumulative-update-10-for-sql-server-2019-b6b696ec-6598-48d9-80ee-f1b85d7a508b) ## Windows Updates: - [Windows Security updates and vulnerabilities for April](https://msrc.microsoft.com/update-guide/releaseNote/2021-Apr) ## In other news: - [Microsoft release the source code for research toolkit CyberBattleSim](https://www.microsoft.com/security/blog/2021/04/08/gamifying-machine-learning-for-stronger-security-and-ai-models/), a platform to investigate the interaction of automated agents in abstract simulated network environments - [Iran Nuclear facility Natanz has gone dark](https://www.theregister.com/2021/04/12/iran_cyber_attack_theory/) in what whispers suggest is an Israeli cyber attack reminiscent of Stuxnet ### Subscribe to Email Updates ## Related posts --- ### [We're in Reading for Data Relay 2022](https://blog.coeo.com/coeo-are-attending-data-relay-2022) ### [New Disk Space Forecasting available for Dedicated Support](https://blog.coeo.com/new-disk-space-forecasting-available-for-dedicated-support) ### [Cyber Security Update: July 2021](https://blog.coeo.com/cyber-security-update-july-2021) ### [Cyber Security Update: June 2021](https://blog.coeo.com/cyber-security-update-june2021) ![](https://www.coeo.com/wp-content/uploads/2016/12/logo-invert.png) +44 (0)20 3051 3595 | info@coeo.com ## Contact Us By clicking submit below, you consent to allow Coeo to store and process the personal information submitted above to provide you the content requested.
