Once you are happy to deploy to all clients you just need to un-tick this option and apply the changes. Those clients you do wish to run the latest version can be manually upgraded. This of course will depend on your setup – in my case I allowed a week. Now all we need to do is allow time for the policy change to progagate throughout the network to all OfficeScan agents. Select the tick box next to this option and then click to ‘Apply to All Agents’. ‘ OfficeScan agents can update components but not upgrade the agent program or deploy hot fixes‘ Unless your support provider has told you to do otherwise, leave the setting as is. By default this will be the Trend Micro Update Server accessed over the internet. Click the ‘Other Settings’ tab, the option we need to configure is highlighted. Go to Administration > System Settings > Updates. Click the ‘Settings’ option and then select ‘Privileges and Other Settings’.Ī new browser window should open allowing us access to these configuration options. Now that we have the root object selected we can start configuring our policy options. Next we need to highlight the root OfficeScan object in the agent tree to ensure all clients receive the policy. As I can’t know what your policy layout is you may actually need to carry out this step differetly but I am going to assume a setup where the policy is being applied at the root level and inherited by all sub-clients. To do this select the ‘Agents’ menu and then chooose ‘Agent Management. If you try and rush ahead with the server side upgrade you may have agents which are running an old policy allowing them to upgrade.įirstly we need to logon to the OfficeScan web management console and modify our agent policy. I strongly recommend you make these changes and then allow a sensible amount of time for all agents to detect the change. In this post I will quickly cover how to disable the OfficeScan management server pushing automatic agent upgrades.įirstly we must consider the following BEFORE upgrading the server side – changes made on the server side will take time to propagate throughout the network. When it comes to a major upgrade I prefer to deploy to a small subset of clients for testing and gradually roll out to more departments over a period of time. ![]() Sometimes you want this, for example you might just be applying a minor hotfix or update which you want all clients to receive ASAP. Typically once the server side software has been upgraded it automatically begins to push out the new program version to all OfficeScan agents. Affected installations will be updated to minimize disruptions and ensure that critical applications and sensitive enterprise data stay protected.I recently upgraded one of our Trend Micro OfficeScan management servers to the latest ‘XG’ (v12) version. Installing Trend Micro™ Deep Security™ and Vulnerability Protection or similar solutions can protect users from threats that target the vulnerabilities in this month’s patch list. Successfully exploiting these vulnerabilities could permit the takeover of the targeted system, allowing an attacker to perform unwanted actions such as installing or uninstalling applications, or even creating new accounts with full administrative rights. Trend Micro Zero Day Initiative (ZDI) provided information on four Microsoft Excel vulnerabilities:Īll four vulnerabilities share the same basic characteristics - RCE vulnerabilities that occur when Microsoft Excel fails to handle objects in memory properly. Microsoft Excel RCE vulnerabilities also present The successful exploitation of CVE-2020-16896 could then lead to a malicious actor obtaining information that can then be used for further malicious acts. ![]() This particular bug can be exploited by an attacker running a specially crafted application against a server that provides RDP services. ![]() With a large number of workers accessing their systems via remote desktop protocol (RDP), the updates addressing CVE-2020-16896 look to be especially important. An RDP-related bug could lead to information disclosure While CVE-2020-16899 can again be exploited via specially crafted packets, unlike the previous vulnerability, it does not allow attackers to execute code or directly elevate user rights. The second of these vulnerabilities is CVE-2020-16899, a denial-of-service (DoS) flaw that also concerns ICMPv6 Router Advertisement packets. An attacker who creates malicious versions of these packets and then sends them remotely could potentially gain the ability to execute code on the target machine. The first, CVE-2020-16898, is a remote code execution (RCE) bug related to the way the TCP/IP stack mishandles ICMPv6 Router Advertisement packets. Two of the more notable vulnerabilities that were addressed involved TCP/IP. Critical TCP/IP vulnerabilities lead the way After a few months where the number of bug fixes exceeded the 100-mark, October’s round of updates stood at 87, containing fixes for eleven that were rated as Critical. Microsoft's Patch Tuesday update for October has a relatively smaller number of patches.
