Motorola GSD Self-Audits • How does it work / what do we do? • 1.) What is an audit? • 2.) What is the procedure? • 3.) What are the “judgement parameters” • 4.) How are metrics (ColorChart) evaluated? • 5.) What are the deliverables • 6.) How can you “prepare your site / people”
What is an Audit… • A "snapshot in time”, taken by qualified people in a field of endeavour to assess the competencies of people, policies & processes for compliance with a set group of guidelines (model), executed over time (in the past) that should, philosophically, predict the competencies of the people, policies & processes into the future.
Audit Schedule -1week/site • Day1: team arrives, intros, logistics, audit team reviews documents (nights?) • Day2-3: interview admin staff / users; audit team reviews documents • Day 4: a.m.: first draft report to admin mgr & MD; p.m.: review action item list • Day 5: help / update support admin staff.
Document Review: • Read policy documents to determine applicability & relevance; under CM, dual author, etc. • Read process document for similar content • Review log-files (raw and/or filtered) for appropriate content. Log-file procedures for applicability. Log-file filtering scripts for completeness & relevance. • Select documents & subject areas at random.
Interview people to evaluate: • Understanding of: • Policy: - what is it, why is it there, what are the consequences of not following the policy • Process: - same • Log-file processes - why & how & consequence • Tailor interview to how the interviewee: • Interacts with the issue (user / manager / admin) • Background, knowledge, culture, impact of issue
Success vs Opportunity: • Judgement calls on Success vs Opportunity and [red / yellow / green] needs guidelines: • Does Policy begat Process which is: • Universally understood by all individuals • Well documented in print / electronic form with CM • Being followed, rigourously, over time with documented evidence, thereof • IF all these are true, then Yellow or Success (if true for one year, then Green)
Success vs Opportunity (2 of 2) • From the Audit Color Chart Legend (pg4) • Green: all (parts of) this subject-area comply and are documented & have been followed for 1 year • Yellow: - very large majority (more than 50%) of this subject area comply (policy, process, both documented, & periodic follow-up) but do not have 1 year of documented evidence. • Red: - some portion of this subject area has no: documented policy, no documented process
Final Report: what to expect (1/2) • Intro: • Who we (audit team) are, what site we audited, what our process was (document review, interviews, etc.) • What subject areas or issues we reviewed: OS security, web-access-controls, router ACLs, DRP/BIA/testing, backup, physical, POPI, others. • Body: • 1 short section for each issue/subject area - as the following example:
Final Report: what to expect (2/2) • What we found: 1 short summary per issue: • In the area of “Web Access Controls” we find: • Excellently written policy, well documented, under CM. • Adopted process / procedure template which covers 2/3 of policy. (template appears to have been adopted from another organization with minimal tailoring for local conditions) • Log-file collection system in place, set of log-file filters run on a regular basis. Little documentation that a human reviews either the raw or filtered logs on a regular basis & reports. • Risk: high = potential for intrusions to go undetected • Color: - Yellow: - there is some support for this area, however, the key point of regular review does not exist
Action Items:(appendix to report) • Action Item List: - one “section” in the report per subject area or issue; example: • Web-Access Controls: • 1.) web-access-controls process template review with admin, legal, hr by: dd_mon_1999 owner: JoeAdmin • 2.) put above document under configuration management by: dd_mon_1999 owner: JennySQA • 3.) write policy for log-file-review by: dd_mon_1999 owner: MaryAdmin
Action Items:(appendix to report) • Select individual to process / document log-file reviews by: dd_mon_2000; owner: MissyLog • Etc. etc. etc. • IF there is excellent policy/process/follow-up then say so. • Orient all recommendations / actions as Positive…
Quick-step to success: • POLICIES of focus areas on ColorChart • are the Policies Documented? • PROCESS or PROCEDURE for the implementation of every POLICY area? • Are these Procedures Documented? • Evidence (documentation) procedure has been followed, over time (1 year, min?)
One-Sentence Summary: • Man-hours on process & documentation.
