A vulnerability in version 3.1.1 of the Server Message Block (SMB) -- the service that's used to share files, printers, and other resources on local networks and over the internet -- can allow attacks to execute code of their choice on both servers and end-user computers that use the vulnerable protocol, Microsoft said in an advisory. Ars Technica reports: The flaw, which is tracked as CVE-2020-0796, affects Windows 10, versions 1903 and 1909 and Windows Server versions 1903 and 1909, which are relatively new releases that Microsoft has invested huge amounts of resources hardening against precisely these types of attacks. Patches aren't available, and Tuesday's advisory gave no timeline for one being released. Asked if there was a timeline for releasing a fix, a Microsoft representative said, "Beyond the advisory you linked, nothing else to share from Microsoft at this time." In the meantime, Microsoft said vulnerable servers can be protected by disabling compression to block unauthenticated attackers from exploiting the vulnerability against an SMBv3 server. Users can use the following PowerShell command to turn off compression without needing to reboot the machine: "Set-ItemProperty -Path "HKLM:SYSTEMCurrentControlSetServicesLanmanServerParameters" DisableCompression -Type DWORD -Value 1 -Force." That fix won't protect vulnerable client computers or servers if they connect to a malicious SMB service, but in that scenario, the attacks aren't wormable. Microsoft also recommended users block port 445, which is used to send SMB traffic between machines.

During a power outage, responsible business owners use emergency power to keep desktop computers from unexpectedly shutting down. While that's certainly a good strategy for keeping machines operational and preventing data loss, there's something else you can do to ensure that your staff remains productive while weathering a storm: uninterruptible power supply (UPS) for networking equipment.

Cloud subscriptions are undoubtedly valuable, but creating a new set of login credentials users have to memorize adds another level of inefficiency. With single sign-on (SSO), you can create one user profile that logs you into all of your online accounts. If you're overwhelmed by the need to create and manage strong passwords, SSO is for you.
