Just in time Virtual Machine access

Published date: 14 September, 2017

Attackers commonly target cloud environments with brute force or port scanning attacks, typically against management ports like RDP and SSH that are left open to enable administrator access. Azure Security Center, in addition to detecting and alerting you to these attacks, has released a new just in time VM access mechanism. Just in time VM access, now in preview, significantly reduces your exposure to these attacks by enabling you to deny persistent access while still providing controlled, audited access to virtual machines when needed.

Based on the security policy you set, Azure Security Center will recommend that just in time VM access be enabled on your existing virtual machines, as well as any new ones that are created. When just in time VM access is enabled, Azure Security Center locks down inbound traffic to defined ports by creating network security group rules.
