What are memory quota
The windows security setting adjust memory quotas for a process, specifies who has the permission to change the maximum amount of random access memory (RAM) that a program or application can access at any specific time. Doing so controls and manages system resources, ensuring the system runs smoothly.
Why adjust memory quota
The adjust memory quotas for a process setting decides who can change a program or process’ memory quota. The ability to change the amount of memory able to be used for a specific program can be useful both in testing and troubleshooting of programs. Often used by developers, it can be beneficial to test a program under restricted conditions, or in the case of a problem, allowing a program to use more memory to troubleshoot.
Why limit memory quota
If a single program were to use too much memory, it has the potential to slow down or stop a system entirely, essentially creating a denial of service situation (DDOS) for the user. Memory quota help to guarantee no single program or process can use too much memory preventing this from happening.
This can also be harnessed for malicious purposes, with attackers using programs specifically developed to use up as much memory as possible, thus causing the system to crash. Memory quotas set boundaries to prevent such attacks from taking place.
How to change memory quota limits
To establish the recommended configuration via GP, set the following UI path to Administrators, LOCAL SERVICE, NETWORK SERVICE:

Best practices for memory quotas
Leaving the default setting for adjust memory quotas for a process is the safest option for most users ensuring efficient memory management. However, this is not always the case and it is important to understand this setting in order to properly protect a system.
With so many security settings, it is impossible to know them all. Server hardening focuses on securing settings to protect against threats by applying patches and limiting access. This can significantly reduce vulnerabilities, enhancing overall security and stability even without complete knowledge of each setting.
