IT Services and Its Wide Applications


Technology is an essential part of university life and IT Services provides the tools and skills to help you study successfully. This booklet will help you explore what is available and answer some of your questions


Printing and photocopying
Almost all public printers in branch libraries, the Computer Centre and a number of other departmental
locations use our Printer Accounting Server system (PAS) which takes credit from a printing account associated  with your UoB account. The same printer credit can also be used on most Canon photocopiers in branch libraries. Colour printing is available in almost all branch libraries and the Computer Centre.

This is in addition to colour printing offered in departments. You can also photocopy in colour in the following libraries: Arts and Social Sciences, Medical, Wills, Chemistry, Graduate School of Education and Veterinary Science at Langford.

How do I print and copy?
All students automatically have a printing account and all new full-time undergraduates will start off with a free £0.50 print credit. You will then need to add additional credit. If you do not have credit, you won’t be able to print. The same printer credit can be used on photocopiers which are available in branch libraries and the Computer Centre. Printing costs start at 5 pence per A4 page.

How do I add credit?
You can check and buy credit and clicking the IT tab. You can also buy credit at the IT Service Desk and any library issue desk.

Can I print and photocopy in colour?
We provide colour facilities for printing and photocopying at the Computer Centre, Arts and Social Sciences Library and in almost all other branch libraries. Colour printing is also available in most faculties and departments.

Why do documents print double-sided?
All our printers default to double-sided printing (duplex), helping the University reduce paper consumption and waste. You can print single-sided if you need to for no extra cost. Do I have access to printing
at any time?

The Computer Centre has a 24 hour computer lab, equipped with fast black-andwhite and colour printing and photocopying facilities. You can use these facilities at any time of the day or night. Other printing facilities are available in libraries and faculties during their normal opening times.

Where can I find a printer?
A general list is available by visiting the web address below and following the link to ‘Printer Accounting Server (PAS)’. You will find that almost all open access rooms and departments have printers. Can I print things from my own computer?

You can print from your own Windows or Mac laptop via the wireless network.

Organizations frequently must evaluate and select a variety of information technology (IT) security services in order to maintain and improve their overall IT security program and enterprise architecture. IT security services, which range from security policy development to intrusion detection support, may be offered by an IT group internal to an organization, or by a growing group of vendors. Organizations can benefit when choices among services and service providers stimulate competition and bring innovation to the marketplace. However, it is difficult and challenging to determine service provider capabilities, measure service reliability and navigate the many complexities involved in security service agreements.

Individuals who are responsible for selecting, implementing, and managing IT security services for an organization must carefully evaluate their options before selecting resources that will be entrusted to meet their particular IT security program requirements. The factors to be considered when selecting, implementing, and managing IT security services include:

the type of service arrangement; service provider qualifications, operational requirements and capabilities, experience, and viability; trustworthiness of service provider employees; and the service provider’s capability to deliver adequate protection for the organization systems, applications, and information.

These considerations will apply (to varying degrees) to every service depending on the size, type, complexity, cost, and criticality of the services being considered and the specific needs of the organization implementing or contracting for the services.

The Guide to Information Technology Security Services, Special Publication 800-35, provides assistance with the selection, implementation, and management of IT security services by guiding organizations through the various phases of the IT security services life cycle. This life cycle provides a framework that enables the IT security decision makers to organize their IT security efforts—from initiation to closeout.

The systematic management of the IT security services process is critically important. Failure to consider the many issues involved and to manage the organizational risks can seriously impact the organization. IT security decision makers must think about the costs involved and the underlying security requirements, as well as the potential impact of their decisions on the organizational mission, operations, strategic functions, personnel, and service provider arrangements.

The six phases of the IT security life cycle are: 
ƒ Phase 1: Initiation—the organization determines if it should investigate whether implementing an IT security service might improve the effectiveness of the organization’s IT security program.

ƒ Phase 2: Assessment—the organization determines the security posture of the current environment using metrics and identifies the requirements and viable solutions.

ƒ Phase 3: Solution—decision makers evaluate potential solutions, develop the business case and specify the attributes of an acceptable service arrangement solution from the set of available options.

ƒ Phase 4: Implementation—the organization selects and engages the service  provider, develops a service arrangement, and implements the solution.

ƒ Phase 5: Operations—the organization ensures operational success by consistently monitoring service provider and organizational security performance against identified requirements, periodically evaluating changes in risks and threats to the organization and ensuring the organizational security solution is adjusted as necessary to maintain an acceptable security posture.

ƒ Phase 6: Closeout—the organization ensures a smooth transition as the service ends or is discontinued.


This guide describes a life cycle that provides a context to assist organizations with managing the myriad issues surrounding IT security services. However, the guide does not prescribe or recommend any specific IT security service, IT security service arrangement, IT security service agreement, or IT security service provider. Each organization must perform its own analysis of its needs and assess, select, implement, and oversee the IT security service to best address its needs.

The Guide should be used in conjunction with other Special Publications (SP) that focus on procurement of IT systems, including  SP 800-64, Security Considerations in the Information System Development Life Cycle, and  SP 800-36: Guide to Selecting Information Technology Security Products. SP 800-55, Security Metrics Guide for Information Technology Systems will help organizations understand the importance of using metrics and developing a metrics program.

Other special publications may be helpful in providing information on specific services and technologies. These include:

ƒ SP 800-30: Risk Management Guide for Information Technology Systems
ƒ SP 800-32: Introduction to Public Key Technology and the Federal PKI Infrastructure
ƒ SP 800-33: Underlying Technical Models for Information Technology Security
ƒ SP 800-34: Contingency Planning for Information Technology Systems
ƒ SP 800-41: An Introduction to Firewalls and Firewall Policy
ƒ SP 800-42: Guideline on Network Security Testing
ƒ SP 800-48: Wireless Network Security: 802.11, Bluetooth, and Handheld Devices
ƒ SP 800-50: Building an Information Technology Security Awareness and Training Program
ƒ SP 800-53: Recommended Security Controls for Federal Information Systems

Recommends that organizations planning to acquire IT security services should:

ƒ Develop careful, objective business cases. The need for an IT security service should be supported by the business needs of the organization. A business case containing an analysis of the proposed solution, cost estimate, benefits analysis, project risk analysis, and an evaluation of other considered alternatives should provide sufficient documentation to describe and support these needs. ƒ Develop strong, specific service agreements that define the expectations of performance for each required security control, describe measurable outcomes, and identify remedies and response requirements for any identified instances of non-compliance.

ƒ Use metrics throughout the IT security life cycle. Metrics will provide the objective data to evaluate the baseline level of service in the assessment phase and assess service provider performance in the operations phase. Wherever possible, metrics should be selected to indicate progress toward the achievement or maintenance of a security condition that meets an underlying organizational need. ƒ Develop processes and procedures that can effectively track the myriad service agreements and the metrics that will be applied throughout the lifecycle of the many different and disparate IT security services within an organization ƒ Ensure that an appropriate transition (bedding in) period is in place between an existing service provider or capability and the new service provider  Maintain the technical expertise necessary to understand and manage the security service being provided and to protect the data critical to an organization’s mission ƒ Pay careful attention to six issue areas: strategy/mission, budget/funding, technology/architecture, organization, personnel, and policy/process.
