October 2020 Patch Tuesday forecast: Trick or treat?

This post was originally published on this site

It’s October and that means Halloween will be here at the end of the month. It won’t be much fun if we only get to ‘dress up’ and look at each other via video conference. But then, we’ve had a lot of ‘tricks’ thrown at us this last month – Zerologon, explosion of ransomware, COVID phishing attacks, and more. Will we get more tricks next week or are we in for a treat on Patch Tuesday?

October 2020 Patch Tuesday forecast

The Netlogon Elevation of Privilege Vulnerability, CVE-2020-1472, also referred to as the Zerologon vulnerability, dominated the news this past month. The US Department of Homeland Security issued Emergency Directive 20-04 on September 18, requiring all government agencies with a domain controller to update their servers within three days.

Microsoft has also issued updated guidance since the August Patch Tuesday release to clarify the steps needed to secure systems with this vulnerability. Per the outlined process in the article, the first step is to apply the August 11 updates which will begin enforcement of Secure RPC (Remote Procedure Call), but still allow non-compliant devices to connect and log the connections. Full enforcement will begin with the deployment of the February 9, 2021 updates.

All systems in your environment should be updated and monitored between now and February to verify they are configured and using the secure channels properly. Once the February updates are deployed, only vulnerable systems explicitly listed in group policy will be allowed to connect to the domain controller.

It’s not unexpected that the education community has been hit the hardest by cyberattacks in the past several months. Students of all ages are now spending many hours online in daily remote learning sessions and are constantly exposed to a full host of attacks. The Microsoft Security Intelligence center is showing that 62% of malware encounters are affecting this industry.

As funny as it may sound, this is partially an ‘education’ issue. Most students haven’t received any form of security training and need to be aware of phishing attacks and what to look for, the importance of strong passwords, the need to keep personal or ‘sensitive’ information private, and similar practices we in the industry often take for granted.

With the sudden increase of connections from personal computers, many of which are running out-of-date software, it is more important than ever to maintain solid security practices for the infrastructure and support systems. Teachers should be running authorized software and IT must be prepared to apply the latest security updates, especially for programs like Zoom, WebEx, GoToMeeting, etc., which are critical for remote learning. We’ll weather this storm and the good news is that we’ll have a more security-aware group entering the workforce in the upcoming years.

October 2020 Patch Tuesday forecast

  • Microsoft continues to address record numbers of vulnerabilities each month. Expect that to continue in October. Microsoft Exchange Server received a major update last month, so I don’t expect another one. But we will see the standard updates for operating systems and Office, and extended support updates for Windows 7 and Server 2008.
  • Select service stack updates (SSUs) should appear as they usually do.
  • The last security updates for Adobe Acrobat and Reader were in August. There are no pre-announcements on their web site, but we may see an update.
  • Apple will most likely release major security updates for iTunes and iCloud later in October if they maintain their quarterly schedule.
  • Google Chrome 86 was released this Tuesday with significant security updates. Don’t expect any updates around Patch Tuesday.
  • Security updates were released on September 22 for Mozilla Firefox and Thunderbird. We could see some additional updates next week.

In summary, expect the standard set of Microsoft releases, maybe some updates from Adobe, and probably two from Mozilla. Based on this limited list of updates, It sounds like we should be in for a treat!
