First Words—What’s the Plan?

When thinking about organizational information security, your mind might jump to the technical details such as firewalls, access control lists, certificates, auditing, encryption, and all those well-known electronic trappings that present a mental vision of a secure architecture. In fact, if you review the security implementations for most organizations, you will indeed see all those things.

Did you ever wonder how those physical and logical layers of security ever started out? I did, and what I found out may surprise you. Despite all the electronic gadgetry, despite the fact that these environments were created by information technologists, despite this being the electronic age, despite the “paperless” society, the best security implementations ... the ones that still stand up to the test of time ... began as a written security plan on good, old-fashioned paper!

If you’re seeking to emulate what other companies have shown to be successful, first you need to have a plan, and then you need to stick to it. That does not mean that you should create the security plan and never modify it, but it does mean that this plan should be solid enough to guide formulation of your organization’s day-to-day database security policies.

In today’s lightning-speed development and production environments, slowing down long enough to actually create a plan may appear to be an unaffordable luxury. Consider, however, that this plan does not need to be an impediment to progress, but rather an empowering document, facilitating the time and commitment of resources that must be dedicated to the security initiative.

If you happen to be a DBA, that written database security plan can be a lifesaver, both on initial database setup and as an ongoing reminder of the symbiotic relationship between the database and the security of the organization’s information assets. It should give you guidance both before and after a database has been launched. It will be an important guide as you formulate your DB2 database policies. It must be an active document, referred to for guidance on a regular basis and updated as change arises. For the corporation’s sake, the database security plan should not suffer the fate of so many others and become yet another a dusty binder stored on the top of someone’s filing cabinet.

Perhaps, one of the most important benefits to be gained from creating a database security plan is that the very act of committing the plan to writing will assist in identifying potential security risks that might not be uncovered in a benign way otherwise. If security is not on the corporate conscious, the true threat is masked by all the tasks and energies required just to keep day-to-day operations or development going. Working on any security plan funnels the combined thoughts of the organization into one readable whole and presents in a clearer fashion the ways to address and mitigate those threats.
