Implementing a Patch Management Process

This tool is a configuration monitoring tool. Rollout Schemes for Business Critical Environments Schemes for Business Operational Environments A business operational environment may not require specific rollout schemes for regularly scheduled, rapid, and emergency rollouts. This might entail completing a change management form that describes the planned changes, the business justifications, list of departments and systems affected, dates, expected outcome, contingency plans patch back-out plan , required resources, and so forth. Method B This method can be used in a business critical environment. This process can be used also to add a feature to a system that is critical to the business service and that cannot wait for more than a month.

Phase 5: Obtaining Change Management Approval and Notifying Other Groups Once the required patch cluster has been created, the next step is to get approval from the appropriate change management authorities. The preproduction environment often closely resembles the production environment and is used for final testing in an environment that has most of the variables found in the actual production environment. If problems are identified during the production deployment, depending on the type of problem, it could be an indication that the lab environment or the test machines need to include additional system configurations or applications. For example, a fictitious company called Fortune 526, categorizes three of their environments into three pools as follows: Mission Critical Business Critical Business Operational Fortune 526 identified their e-commerce services as the mission critical component of their compute services because this environment is used to sell the company's products and services online. The integration environment is also often used for endurance testing, failure testing, and load testing of applications after applying Solaris patches. Perform this analysis on a monthly basis to ensure that your mission critical services are as up-to-date as possible.

Use the Patch Finder to display a specific patch description. To access the Management Templates, expand the Configure Templates option within the Functions Window, and the then click on Patch Management. Waiting for the operating system or application to release a patch is not sufficient. There are five columns showing five different systems. The following methods offer some ideas. Review the threats and vulnerabilities to determine the risk and prioritize.

In addition to maintaining up-to-date configuration data of one or more systems, i-status can be used to monitor and compare patch levels of various systems. If the patch rollout results in minor changes the implementation management portion can be skipped. Phase 7: Performing Ongoing Patch Maintenance Even though following the previous phases keeps the patches up to date on all the systems, there can be occasional emergency rollouts. A simple way to automate this maintenance process is described below. More information about each tool is available from the Patch Portal at.

Metrics can help to validate that your patch process is effective and provide valuable information that can demonstrate the security posture to the business in a meaningful way. If problems are encountered, software developers can correct the problems or you can coordinate with Sun to resolve any problems. . I recommend periodically reviewing the operating systems and applications and work to reduce the number as much as possible. Sometimes you must support old software.

When it comes to security patches, it is a best practice to apply all Recommended and Security patches, and then be selective about all other patches. Phase 6—Execute the patch cluster rollout. Use this environment for endurance, stress, and regression testing, inducing heavy loads on the systems that are equivalent to the mix of loads that will be generated in the actual production environment. Phase 2 - Identification and evaluation Once you have a handle on what is running in your environment, you can use that information to determine whether or not a particular patch applies to your systems. If you seem to have more viruses and worms than before, patching could help.

Sun alert patches Temporary patches for recently discovered problems. The system must be in a quiesced state when a backup is taken. If this environment is not available even for a few minutes, the impact is very high, including loss of revenue and customer satisfaction. If you do not have a process in place or are taking this time to review and update, the has provided a good methodology on how to implement a patch management process. The breach occurred from mid-May through July where the attackers could access names, Social Security numbers, birth dates, and addresses. This can vary depending on whether each one of these sub environments are physically separated. Typically, this is a situation in which a mission critical system has a serious problem, and after analysis, it is found that one or two patches exist that would fix the problem.

The rows that have underlined patches show patches that are out of revision level. You should also test that your rollback procedures work in case of problems. While you should explain to the executives what it is and how it's done, sometimes a flow chart can help. A low risk somewhere else in the organization may increase the risk for a given threat or vulnerability. Effective use of the tools that are available in Sun's Patch Portal from the SunSolve Online program is essential. Phase 2 outlines a patch rollout scheme for each type of environment pool, taking into account the need for quick solutions emergency rollouts to those environments that can follow the standard change process rapid and regularly scheduled rollouts. The patch store can be used to generate a list of all systems and environments in which a particular patch has been applied.

My latest role is in information security, focusing on multiple areas including log management and security incident investigation and response. This article assumes that your senior system administrator and the senior system architect have the expertise to use the patch management tools to come up with a customized patch cluster for your target production environment. Approvals must be obtained before moving to the next step. The scheduler can also be configured to remind the you to check the i-status console periodically. Common Issues and Roadblocks Without getting into too much detail, I wanted to point out some high level issues and roadblocks originations may run into when trying to implement and following a patch management process. Along with the metrics, an additional item that often get missed is to verify the patch actually remediated the vulnerability.

The back-out script uses the saved objects to restore the software to pre-patched state. This scheme moves the patches into the environment sooner than the regular rollout scheme, but still gives them a total of one month for endurance testing the patches before moving the patches into production. In some cases, the attackers were even able to steal credit card numbers. The more critical your environment, the more selective you should be in building your patch cluster. Select the systems, right click and choose Patch Management.
