Large corporations as well as small businesses have begun to turn to automated patch management software for security and updates. The average user has become used to the security updates and fixes and businesses have much more to secure against. The frequent patches and additions to the Windows operating system has accustomed the consumer to the need for fixes on a regular basis.
Most home users will enable automatic updates for the Windows operating system and this is a specific and limited type of patch management software. There are many more programs on almost every computer which also require patching. For the larger company or business, this can be a time and labor intensive job keeping up with patches and securing the system.
However today there are multiple choices in programs for managing updates and patches automatically or semi automatically. Security of the company assets is a primary source of concern for many businesses and enabling the latest security fixes provides enhanced security and functionality to the programs. Although these patches are essential they can be time consuming in larger operations if patch software management is not used.
This type of software will utilize a console usually on a single machine of a network. That console can control what fixes or patches are scanned for and how the patches are deployed throughout the system. Included in these software consoles are options also specify which from which sites a patch should be downloaded. Some management software companies maintain their own database of patches and fixes.
Most computers on the network have specific functions and some will have different programs to carry out those functions. A management program for fixes and patches can scan the system and update those programs requested. Unlike a macro the programs can be configured to scan each machine or their own contents and then apply only those patches which are necessary for that specific machine.
There are generally two types of management software for patches. The first type is an agent based management solution. Management programs that use the agent have a program installed on each machine, which performs a scan of the machine. This agent then downloads and installs necessary fixes and then sends a message to the central machine concerning what programs are installed and updated.
Agentless management programs on the other hand are centralized. The main machine performs all the scans upon the network and initiates the actions to patch. While agentless software is certainly more centrally configurable and permits closer monitoring of network machines than an agent based option. The cost for these programs will be higher than that of the agent based solutions. They also will require more supervision than those with agents.
Whichever method is chosen the patch management software alternatives tend to save time and help improve security. This is particularly true when patching a large network with many machines. Before a decision is made in favor of agent or agentless software the business should assess the available work force, security needs and bandwidth of the company. While the agent based solution is more bandwidth intensive, it requires less supervision. The agentless method requires less bandwidth but is ultimately more controllable.
