Q1.

The Security Life Cycle Model is a process that helps in maintaining an acceptable level of security in industrial controls systems and networks. The model begins with deterrence and ends with correction. In your own words, describe this process while incorporating an example (e.g., of how to deter XX and how to prevent XX and so on through the cycle). Your reply should be a minimum of 1 paragraph. A paragraph is 3 sentences minimum and 5 sentences maximum. It is OK if you go beyond 1 paragraph.

Q2.

NIST 800-82 is a guide to Industrial Control Systems (ICS) Security, which SCADA falls under. Select one control, identify whether the control falls under Management, Operational or Technical Controls and explain what this control helps mitigate in a SCADA system? Provide an example of this control in a real world situation (for example you can refer to one of the case-studies and explain how XX control could have mitigated Y). Your reply should be a minimum of 1 paragraph. A paragraph is 3 sentences minimum and 5 sentences maximum. It is OK if you go beyond 1 paragraph.

N.B incase you would like to use case study as example let me know to provide you

Q3

1.Security events are those events generated by security and infrastructure products (e.g., firewalls and network routers).

True

False

2. A false negative is when a real threat fails to create an alert.

True

False

3. System logs are useful for:

Tracking the status of a device.

Reminding users to shutdown their systems.

Tracking services that are running.

Tracking when patches should be applied.

4. The problem with Configuration Management within ICS is that a large portion of the critical configuration information is retained in embedded devices often running proprietary or closed operating systems using non-standard communication protocols.

True

False

5. Relevant security inforamtion comes from various places such as the network, assets and hosts which all provide for:

Information to be archived.

Situational awareness needed to effectively secure an industrial network.

A security plan.

Monitoring of an industrial network.

6. Common standards and regulations for ICS include:

CISSP manual

NIST SP 800-82

ISO/IEC 27002

NERC CIP

7. Unlike other standards, Common Criteria and Federal Inforamtion Processing Standards aim to:

Certify security products rather than security policies and process.

Provide guidance on polices.

Regulate industrial systems.

Modify code.

8. Security products are also subject to regulatory requirements.

True

False

9. Which NIST publication provides guidance on security controls for federal information systems?

NIST SP 800-82

NIST SP 800-53

NIST 800-167

NIST 800-171

10. Understanding how regulatory standards and regulations can impact the security of a network or system will help at all stages of industrial network security planning and implimentation.

True

False
