““Inconsistent dataInconsistent data””

Healthcare Insurer: “My team is responsible for sending data externally to many of our business partners and other entities. The number of these requests has grown significantly over the years and they are becoming increasingly involved and complicated. We need a policy and process to handle these requests to ensure we comply with all privacy/security regulations. We also need appropriate executive-level review and approval to ensure that each request for sharing our data externally is the right thing for us to do from a business perspective.”

““We need a policy and process to ensure we are protecting our datWe need a policy and process to ensure we are protecting our dataa””

United States Government Agency: “Our team is responsible for the trustworthiness of data to the field analysts but we have no control over the quality of data that flows into our Financials from SAP R/3 to BW.”

““We have no control over the quality of dataWe have no control over the quality of data””

North American Multi-Line Insurer: “Our new CEO became the most ardent supporter of Data Governance when he discovered that reports from different parts of the organization had inconsistent data.”

““We keep everything foreverWe keep everything forever””A large chemical manufacturer fails to destroy content and records in accordance with their corporate retention policy and are now burdened with the high cost of managing storage and eDiscovery with no visibility into what to destroy and when. “During eDiscovery, we spent over $12 million dollars reviewing documents that were already past their retention dates and should have been disposed of … and this was on just 4 cases … at any point in time we have over 100 cases pending.

Threats to database and legacy data

Privileged User access to data from outside of the DBMS–Access to DB2 Linear VSAM datasets

Privileged User access to DBMS Data via SQL/DL1 –Abuse of privilege without business Need to Know

External Threats –SQL Injection (Hacking)

Movement of data outside of the DBMS–Unloads–Clones–Test Data–Replication



10

10

Defense in depth of DBMS data

10

Level 1: Encryption - Access to clear text data must be in the form of a DBMS statement

Level 2: Database Activity Monitoring - Ensures each DBMS statement is inspected, audited, and subject to security policy control

Level 3: Audit access to VSAM linear datasets

Level 4: Implement business need to know control for critical data Reduce abuse of privilege access

Level 5: Protect the use of unloads and extracts



But…System z is already secure….why do we need more?

Separation of duties –Privileged users “need to know” vs abuse or

mistake–Trace-based auditing controlled by privileged users–SAF plays a vital role in protection of data on z/OS,

but is not tamper-resistant and actionable

Achieving audit readiness is labor-intensive and introduces latency

–RACF lacks sufficient granularity for reporting–DB2 Audit Trace significantly improved in V10, but

still requires externalization to SMF and customer provided reporting infrastructure

Real time event collection – Batch processing of audit data from external

sources prevents real time alerts

The results that may be obtained in other operating environments may vary significantly.



The benefits of shared collectionUtilizing Shared Collector technology, the Monitoring and Auditing products work together.

– Common processes are used to minimize overhead.– Coordinated use of algorithms, memory, and gathered information reduces the

impact on the statement being observed.– This results in lower CPU consumption and better elapsed time.– Shared Collector code is also more reliable and stability is improved

Agenda






Wrap up



Planning that first implementation

Start with the basics– Identify a non-production DB2 environment– Determine how many DB2 systems to audit– Identify the support people (systems programmer, security administrator, auditor)– Obtain management approval– Establish agreement on the implementation schedule

Establish the Guardium details– Determine what type of collector will be used (VM or hardware)– Identify what features are needed (redundant collectors, zIIP availability, integration

with distributed Guardium systems, etc.)– Identify the TCP/IP addresses– Coordinate the Guardium training and professional services– Size the environment for a collector, aggregator and central manager– Determine what groups to be used to simplify the Guardium implementation

Identify success criteria– What needs to be audited (very important!)?– What reports are required and desired?– Is integration with another product, like a SIEM product, required?– Is a performance test required?– Are Vulnerability Assessments and Entitlement Reports required?



Sample implementation timeline

1. Perform parallel activities – 2 days– Obtain S-TAP software and maintenance

from Shop z– Obtain collector software and maintenance

from Passport Advantage– Coordinate implementation activities

2. Install S-TAP and collector software – 1 day

3. Begin collecting basic auditing – 2 days

4. Refine auditing and create custom reports – 8 days

5. Integrate InfoSphere Guardium with other products – 5 days

Total deployment of first implementation = 18 days(Your mileage may vary)

DB2 collection policy definition

Identifies what activity is to be sent to the Guardium collector for auditing

Uses groups to simplify administration

Key component in performance. For example:– Granular control over connection type– Connection type provides efficient filtering



Agenda






Wrap up



Conducting that first implementationInstall the Guardium collector / aggregator / central manager

–Install the software and maintenance–Configure the installation–Power up the collector

Install the Guardium STAP–Install the STAP and maintenance on all DB2

systems to be audited–Configure the installation and start STAP

Validate auditing–Create a simple audit collection policy–Use reports to validate that DB2 activity is being

stored in the repository

Refine the auditing –Filter unneeded audit data using policy–Create custom reports, Vulnerability

Assessment, integration, etc.



Conducting that first implementationMeet all functional requirements

– Develop detailed custom reports– Modify the collection profile for efficiency, alerts,

exceptions, etc.– Develop an archive strategy– Implement report workflow

Conduct performance testing– Build a repeatable performance test– Run the test– Review the results and make modifications until

results are satisfactory

Plan for ongoing maintenance– Recommendation: Use same maintenance

philosophy that you use for DB2 (eg LPAR or group level)

Plan for the next stages– Obtain approvals to migrate software to production– Schedule migration to next stage– Coordinate migration plan



Agenda






Wrap up



Rolling Guardium into production

Building the production Guardium solution–Size Guardium for the number of STAPs, collectors, aggregators, etc.–Size the number of collectors based on estimated audit data volume

and include failover contingency • And plan for the unexpected!

–Integrate Guardium into your disaster recovery strategy

Post production deployment–Monitor the collector usage closely for the first few weeks –Validate reports are meeting business requirements–Adjust collector sizing as appropriate–Adjust collection policy as appropriate–Deploy the archive strategy



Agenda

How InfoSphere Guardium on System z Provides Value





Wrap up



Getting started with database monitoring

Produce the audit reports–Identify the contents of the report–See if there is a pre-built report that meets your

requirements–Use the Guardium GUI to build a custom report

Monitor the system for "expected" results - make sure things are reasonable and expected

Apply changes based on experience



Building the Guardium reports from the collected data

Guardium has over 100 pre-built reports including accelerators for PCI, HIPAA, SOX

Copy and modify existing reports or build your own using rich custom report builder

Use runtime parameters for rapid subsetting of the data:

–Changing the date ranges Changing the DBMS subsystem names

–Changing the user(s) ID that submitted the requests

–Many more options

Query builder for reports

Entities and attributes



Sample DB2 for z/OS Audit Report

Can mask values to avoid sensitive data leakage

Reports can be automated and run on a schedule

Reports can be routed to reviewers and approvers

34

Network vs local traffic

SQL with bind values

SQL with redacted values



Automating reviews and signoffs - ExampleBusiness Owner

(PCI Role)Information Security

(InfoSec Role)Guardium Admin

(Admin Role)

Reviewer can add comments, which are saved in audit

trail.



Agenda

How Guardium on System z Provides Value





Wrap up



Keys to a successful implementation

The more you plan the fewer surprises you will have –Know the difference between monitoring and

auditing–Log only what the business needs–Get the broader team involved as necessary

(network, DBA, infosec)

Take advantage of IBM Professional Services –Quickly and efficiently deploy Guardium while

minimizing disruption to ongoing projects–Create deployment plans and architecture that

can expand and scale–Deploy basic monitoring and provide step by step

guidance for advanced monitoring if required–Educate your team at every step to accelerate

self-sufficiency



Bottom line

SAF (IBM RACF and CA products) plays a vital role in protection of resources on z/OS, but you also need audit event collection/reporting which is tamper resistant, real-time, and actionable.

InfoSphere Guardium on z/OS provides– Real-time, actionable activity monitoring and alerting– Tamper resistant audit repository– Clear separation of Roles and Responsibilities– Granular insights into activity– Automation, process consistency, and unique security

insights

Bottom line…..you need both RACF and Guardium for a robust security environment on z/OS
