The Top Seven Tips for IR Policies
By Leighton Johnson, CISA, CISM, CIFI, CISSP
Incident response (IR), one of the five domains of the Certified Information Security Manager® (CISM®) certification, has great value to IT security professionals. Each incident is unique, but there are some common policies that need to be in place for proper preparation of the response team and the corporate staff. Here are the top seven policies necessary to help prepare for an incident response effort:
- AUP—The corporate acceptable-use policy (AUP) defines the actions allowed by the computer user on the machine or network. IR personnel need to know this policy so that they can determine what activities are normal and what activities are not acceptable on the computer or the network.
- Containment—What are the first steps to be taken by incident responders? When approaching an incident scene, review what is occurring on the computer screen. If data are being deleted, pull the power plug from the wall; otherwise, perform a real-time capture of system “volatile” data first. Evaluate what network or systems are being affected.
- Version control—What is the corporate patch management policy? By whom and when are patches tested, loaded, evaluated? Who controls the configurations of the servers and network devices? All of these questions should be answered in the version control policy that gives the incident responder the baseline to work from when investigating an incident.
- Communications—This policy covers who communicates to the corporate staff, the users, the workers, and the customers and clients of your organization when something happens. By whom and how the issue is communicated to the shareholders, the public, the media, and even local emergency and law enforcement officials should also be included in this policy.
- Reporting—Clearly define to whom and when the various activities are reported. Just as important is who is not reported to, since an incident could have an “insider” component.
- Backup—This policy sets the boundaries for recovery from the incident. How far back in time is the data retained, where is it, what are the procedures for the daily, weekly and monthly backups of the server or network data? These questions are answered in this backup policy, which the incident responders need to properly return the system or network to normal business operations.

Lack of awareness and knowledge, coupled with a “don’t care” attitude, has led to a plethora of information security problems and mounting losses.
Business, industry and society are alarmed at the systematic attacks of ever-increasing magnitude, scale and frequency. Information security is something that touches our lives every day and no person can afford to ignore it.
A good knowledge of information security fundamentals, concepts, principles, issues, techniques, tools and practices has become essential for the survival of IT systems and businesses.

It addresses a wide range of audiences, without compromising on details, and is fun to read. The book provides a good introduction to information security, especially to those who are novices or are wary of techno-babble, and does so in a humorous way that entertains yet instructs the reader in information security technology and practices.
The book focuses on information security and is useful as a how-to reference. The chapters cover the background and need for information security, physical security, technical security, administration and training. Overall, it provides a management perspective as well as a practical technical approach to information security, using an easy-to-read and interesting presentation style.
