Your chief information security officer (CISO) just decided your company needs the latest and greatest security tools for patching, checking system health and advanced threat protection. The target date for completion? Yesterday. However, it has been several years since you’ve had to manage a tools rollout. Your company needs to deploy a new security tool. Where do you start? The following is a list of activities to consider when planning your security intelligence tool deployment:
1. Know Who Your Stakeholders Are
Identify the senior management stakeholders who are representing users of the tool and obtain their commitment to supporting its successful deployment and adoption. Without their support, it is often difficult to obtain staff members and prioritize their work to complete the required tasks. It can also be a challenge to persuade people to use the tool. It is important to obtain formal, written signoff from stakeholders indicating they agree with the results for all tasks.
2. Perform a Thorough Evaluation of the Tool
Insist that you be given the time and resources for a hands-on evaluation of the product. You need to assess how it will perform and scale in your environment and whether it will support your business processes. If possible, perform a pilot with real users. Pay close attention to the reporting capabilities and determine whether the default reports are sufficient or can be easily enhanced.
3. Disclose the Power of the Tool and Discuss Any Associated Risk
Document and communicate the level of access the tool allows its administrators to have on managed systems. Many security tools have agent software that runs with “root” or “administrator” access, which allows application administrators to have an elevated level of access.
4. Define the Device Types in the Scope of Your Deployment
Document what is in and out of scope, including specific device types, operating systems, application names, network devices and backup systems. Be sure to include details such as the types of hardware models and software versions.
5. Create a High-Level Plan
Create a list of project milestones, the staff needed and the estimated costs. Make sure the stakeholders agree to support the plan and that funding and staff are available before you proceed.
6. Agree on Exit Criteria
Exit criteria are a list of functions that must be enabled, activities that must be completed and requirements that must be satisfied before the tool rollout can be declared complete. They demonstrate that the tool is in a deployed state that meets business requirements. Be sure that the criteria are specific, including factors such as the percentage of devices to which tool agents are deployed, the list of security rules configured and the names of reports being produced.
7. Create a Formal Project Plan With Dates
Develop separate plans for each tool and type of device. Clearly distinguish between server, desktop, network and mobile, and ensure distinct projects are run for each. If you try to commingle the projects, the plan will become very complicated, especially when specific tasks that are applicable to each type of tool or device are discovered.
8. Assign and Commit Resources
Make sure people are available and committed to do the work and that any required equipment, physical space or other resources have been procured and are ready for production.
9. Determine the Baseline for the Device Inventory
Create an inventory of all devices in scope, and don’t deviate from this during the deployment. If you must deviate due to the installation of new devices — or the removal of old ones — use a formal change management process to update the inventory list. This list is extremely important when determining whether the exit criteria have been met for the project, so manage and control changes carefully.
10. Begin the Security Intelligence Rollout
Deploy the solution to any test and development systems first. Then, go from the least to most critical production devices. Address any issues promptly and formally adjust and communicate any changes to the plan that are needed.
I hope this post has helped you plan for your next tools rollout. Please tweet me @LisaChavez111 if you have any suggestions on how to make this security intelligence process easier for others.
