Patch management software has become more popular over recent years with businesses both large and small. Frequent fixes to the windows operating System fix security issues and sometimes add functionality to the programs. They have also gotten the consumer used to the fact that most programs require patches.
A computer user in a home environment will often allow Windows to automatically search for, and apply patches or security packs on an automatic basis. In the corporate or business environment, the same is true, however there are additional programs running that must also be fixed in order to ensure a system is up to date and secure. Taking the time to research and assess each program on each machine could be a task that consumed labor and expense for businesses prior to the introduction of patch software.
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.
These programs usually have a special console and it may well be located on a single master machine on the network. The master console can determine which programs should be patched and which should be overlooked. The user can also determine from which website a patch should be downloaded.
Not every machine on a large network will have identical software installed. These machines all may be used for different purposes and this influences what programs are installed. Patch management programs for businesses are able to scan each machine and identify what programs are present and may need patches as opposed to simply applying a set number of fixes or patches to all machines regardless of content.
One very common type of management program for patches is that of the agent based software. This solution employs an agent, or small program on each machine. The agent scans the machine and makes the necessary changes. When the changes and scan are complete the program reports the results to a central administrative machine.
Other types of management programs use a central machine as the controller. This central computer with a program on it scans each of the machines in the system applies the necessary system changes on the targeted computers in the network. This is known as agentless management in that the only requirement for the other machines is that they be connected to the network, instead of the internet as is required for agent based solutions. The agentless type of management software requires more direct supervision than the programs which reside on individual machines.
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.
