A Study About Iso Information Technology Essay

Control that all the admission rights are distant and equipments are returned when employees, contractors or third-party are complete or reassigned.

Thither should be a ball disciplinal operation for employees who let attached a certificate break. Restraint includes:According to organisations Data and Protection Insurance, roles and responsibilities of workers and contractors should be unclutter and attested. This includes: Both these documents i.e. ISO xx septenary thou two and 20 7 k one are intended to be secondhand unitedly, as one regard the early. Essentially, ISO xx seven-spot grand two standards is a cipher of rehearse for entropy surety which outlines all the likely controls and restraint mechanisms that may theoretically be enforced, with the steering provided inside ISO 27001. The required requirements for an Entropy Certificate Direction Scheme (ISMS) are officially outlined by ISO xx 7 g one whereas the worthy data surety controls inside the ISMS are tending by ISO xx sevener grand two which is a bare guidelines sooner than a authentication received.

This can be through by providing rules that explains protection mastery expectations.Rubber of equipment besides depends upon the tribute from the interruption caused by nonstarter of the support utilities ilk telecom, superpower, water, sewerage, HVAC, etcetera.Restraint includes:


The organizations are release to prime and enforce substitute controls discount any of the controls as none of the them are mandatary, but if an organisation chooses not to dramatise something as canonic as, say, antivirus controls, they should be inclined to apologise their determination done a noetic hazard direction determination summons, if they foresee organism ISO xx 7 chiliad one qualified.“ISO xx septenary grand one incorporates a compendious of controls from ISO xx sevener chiliad two below its Wing A. In practise, organizations that assume ISO xx vii chiliad one too well dramatize ISO 27002.”[3]

The measure “constituted guidelines and oecumenical principles for initiating, implementing, maintaining, and up info surety direction inside an administration”. A ball peril judgement is compulsory to place the particular requirements which are addressed by the controls listed in the criterion. The criterion besides provides a pathfinder for the ontogenesis of “organisational protection standards and efficient protection direction practices and to assistance anatomy authority in inter-organizational activities”.

Regime: ISO-27002:2005 8.3.1.; HIPAA 164.308(a)(3)(ii)(B-C);

Access rights to information and information systems should be removed upon termination of the employment or contractual relationship. Control includes:

other employees, contractors and third parties are appropriately informed ofa person’s changed status; and

Responsibilities must be assigned to the persons for actions taken or not taken according to the sanctions policy.

The main purpose of ISO twenty seven thousand two is to provide a comprehensive information security management program for any organization which either require a new information security management program or wants to improve its existing information security policies and practices. The standard gives the recommendations for managing the information security to the people who are responsible for initiating, implementing and maintaining the information security in any organization. ISO/IEC recommends that every organization should considereach ofthese practices when they establish or improve their organization’s information security management program.However, the implementation of each and every security practice is not necessary as every company would have a unique set of information security risks and requirements would also be different. So, a company can pick and choose the information security practices that according to its own security requirements and ignore the one’s that doesn’t apply to them.Authorities: ISO-27002:2005 9.2.5.; HIPAA 164.310(c) Authorities: ISO-27002:2005 8.2.1.




All the information processing and storing facilities should be isolated from all these access areas as far as possible.

Appropriate entry controls should be put in place to protect the secure areas and to make sure that access is given to only authorized personnel. Control includes:

Authorities: ISO-27002:2005 8.1.2.; HIPAA 164.308(a)(3)(ii)(B);

Proper personnel security measures ensures:

Design and implementation of the physical protection against damage from natural and man-made risks like fire, flood, explosion, wind, earthquake, civil unrest, etc should be considered carefully. Control includes:

There should be backup power cabling and redundant routing of transmission media especially for the critical systems.

Information security is a broad topic and therefore ISO 27002, has ramifications in all types of organisations including commercial enterprises of all sizes, non profit organizations, government agencies, charities, and any other organization that handles and depends on information. [3]

Establish a formal disciplinary process that must be used to handle security breaches.

Authorities: ISO-27002:2005 9.1.6.

3.8 Communications and Ops Management

Physical security of information and information systems not only means protecting them from unauthorised physical access by people but also means that it is important to protect from other physical and environmental elements. The protection of IT equipment is also essential to protect the information an information system fromdamaged by accidents or sabotage.

There should be a limited access to all public areas as well as the areas used for delivery, loading, unloading, etc

Training should be given to all employees, contactors and third party personnel about the organisations security policy as well as security procedure relevant to their job.Control includes:

a reasonable evidentiary standard toinitiateinvestigations(reasonable suspicion that a breach has occurred);

Protection of cabling should be done by using physical methods to avoid any damage or unauthorised interception and the critical systems should be provided with additional security measures.

Security risk can be minimized ifemployees, contractors and third-party

There should be individual measures to manage and minimize all the physical threats like fire, water, smoke, electromagnetic radiation, theft, damage, electrical variance, etc.

Another important point is that ISO twenty seven thousand two is e generic standard and not an industry specific standard. This means that the guidelines should be modified according to each industry and which again might lead to some big holes in the security. This issue is now being addressed by ISO and thus the future plans for ISO twenty seven thousand two mainly focussed around the development of industry specific versions like health sector, manufacturing, etc.

The secure deletion of the data should be done with the use of methods that are generally accepted and it should be in accordance with the sensitivity of the data known or believed to be on the storage media.

“Anyone else with legitimate access to business information or systems is covered”

The cables and equipment should have clear markings for identification unless it is required to hide the marking in order to enhance security.

know how to use organisation’s information processing area.

1.Introduction to ISO 27002

Human Resources security helps in reducing the human mistake by defining job description and resources. It ensures that staffs understand what their rights and responsibilities are relating to information security. Most organisations require their staff to report security incidents and evident weaknesses.

any post-employment responsibilities are specified in the terms and conditions of employment, or a contractor’s or third party’s contract;

3.11 Information Security Incident management

Areas that contain information and information processing facilities should be protected by securing the perimeters by using walls, manned reception, controlled entry gates and doors, and other measures. Control includes:

There should be proper planning and implementation of physical security as well as safe procedures to work in the secure areas should be on place. Control includes:

“acceptable use of assets agreement”

making sure that all eventual employees or contractors understand their responsibilities and are suitable for the roles they will be given. This must be done before any of above is allowed to use the facilities.

To make Information Security Management system effective employee training is extremely vital. It must explain the rights as well as responsibilities for example access to individual files under the Data Protection Act.

All information assets should be protected from unofficial access, use, alteration, disclosure and destruction. To keep the organization’s critical or sensitive information processing facilities by putting them in secure areas, by using defined security perimeters, applying appropriate security barriers and using proper entry controls.

3.7 Physical Security

a reasonable evidentiary standard to determine fault, that ensures correct and fair treatment for personssuspected of a breach;

Equipment that requires special protection should be isolated from the equipment that requires general protection.

The processing of organisation’s information from off-site areas should be tightly controlled with proper authorisation of every access.

sanctions that appropriately take into consideration factors such as the nature and gravity of the breach, its impact on operations, whether it is a first or repeat offense, whether or not the violator was appropriately trained, whether or not the violator exercised due care or exhibited negligence;

Appropriate level of knowledge of security controls must be achieved among all workers and contractors applicable to their job roles.

Organization’s information security policy should be followed while carrying on with execution of processes or activities particular to the individual’s role. Use secure areas to protect facilities and special controls to safeguard supporting facilities.

The objective of this category is to prevent unauthorized physical access, damage or interference to the premises and infrastructure of the organization by usingcontrols appropriate to theidentified risks and the value of the protected assets.

Authorities: ISO-27002:2005 9.2.7.;HIPAA 164.310(d)(1)

Responsibilities for performing employment termination or change of employment should be clearly defined and assigned. Control includes:

All the entry and exit points including any access areas for loading and delivery should be tightly controlled for unauthorized access to the premises. Control includes:

* To avoid disruption to work or damage to the equipment in the case of failure of any supporting utility, backup facilities like UPS should be available.

This section deals with the protection of the organization’s equipment from theft, damage, loss, etc to safeguard the assets of the organisation as well as to avoid interruption of work.

The staff and the third party contractors should be aware of their responsibilities towards the protection of the equipment and the information as well as the risks involved with the off-premises environments.

An organization’s equipment should be protected against the environmental threats and hazards as well as human threats. This should be done by managing the siting and protection of the equipment such that it reduces the environmental risks and opportunities for unauthorized access. Control includes:

There should be proper guidelines for activities likeeating, drinking, smoking or other activities in the vicinity of equipment to prevent it from any physical damage like liquid spillage, fire, etc.

Under normal operating conditions, the supporting utilities should be sufficient to support all the equipment properly. Possible security risks to the organisation and its possessions must be reported as soon as possible.This includes providing organizational code of conduct to the worker, contractor or third party. They should be required to sing before access is given to information or information processing facilities: For safety purposes, the secure areas should always be supervised and all the work in the secure areas should always be monitored for safety as well as to avoid any unauthorized activity.



Management should establish policies and procedures of the business and should require every person to apply security controls accordingly. This includes:

Only limited personnel should be aware of the secure location as well as their knowledge should be limited to the requirement.

changes of responsibilities and duties within the organization areprocessed as a termination (of the old position) and re-hire (to the new position), using standard controls for those processes unless otherwise indicated;

Removal of property should be strictly controlled and prior authorization should be required to remove any equipment, software or information from the premises. Control includes: To protect the organization’s equipment from damage, loss, theft, physical threats and environmental threats in order to avoid interruptions in work as well as unauthorized access to the organizations information.

3.1.2 Secure areas

Designed and implementation of the physical security for offices, rooms and facilities should be done. Control includes:

Prior to employment, organisations should ensure that everyone understands their responsibilities and are suitable for the roles for which they are considered. This will help in reducing theft, fraud or misuse of facilities.

Maintenance should include proper security measure like supervised maintenance which should be in accordance with the degree of sensitivity of the information or the criticality of the equipment, clearing of information and the maintenance should be done only by authorized personnel or contracted third parties.

All staff, contractors and third-party users should sign and agree to terms and conditions of the employment, which must state their rights and responsibilities towards the organisation and the information security. Signed agreement must include:

Authorities: ISO-27002:2005 8.2.2.; HIPAA 164.308(a)(5);

Siting of equipment should be managed such that the unnecessary risks to the equipment is curtailed and need for unauthorised access to the sensitive areas should be minimizes.

Suitable background check should be carried out for all the candidates, this is also known as “screening”.

This section focuses on the physical aspects of security of the information as well as the information systems. For maintaining the confidentiality, integrity and availability of the information a proper physical environment for systems, records and staff is crucial.

appropriate investigatory processes, includingspecification of roles and responsibilities, standards for collection of evidence and chain of custody of evidence;

Authorities: ISO-27002:2005 8.1.3.

Secure disposal of all equipment is a necessary practice for the information security. All the storage media in the equipments should be checked to ensure secure deletion or overwriting sensitive data and licensed software before disposal or re-use. Control includes:

The personnel who are given authorization to take equipment o rinformatio off the premises should be made aware of the security risks involved with off-site environments and should be given relevant training for appropriate controls and countermeasures.

Authorities: ISO-27002:2005 9.2.6.; HIPAA 164.310(d)(1)

This category makes sure that everyone in the organisation is aware of the information security threats, their responsibilities and liabilities and is trained to support organizational security policy and to minimize human error.

All employees, contractors and third-party must be provided with an adequate level of security education and training. They must be aware of organisation’s security procedures.

Make managers responsible for ensuring that employees

Authorities: ISO-27002:2005 8.3.3.

The secure deletion of sensitive information should be done by appropriately trained personnel or should be verified by an information removal specialist.

All employees, contractors and third parties should return all of the organization’s assets in their possession upon termination of the employment relationship or contract. Control includes:

There must be a systematic procedure for employees, contractors and third-party to follow when they leave the organisation or change their work assignment. Managers must be made responsible for controlling the procedure. The areas that are not in use within the secure area should be kept locked as well as monitored remotely through video surveillance. Inspection of these areas should also be done regularly. carry out their security responsibilities throughout the





3.13 Compliance

“This section ensures that employees, contractors and third party users exit the organization, or change employment responsibilities within the organization, in an orderly manner.”

The type and the amount of information or equipment that may be taken off the premises should be limited and should be controlled by logging the authorizations for removal of property and the inventory of equipment and information taken off premises.

3.4 Organization of Information Security

To conclude, although ISO twenty seven thousand two is a good set of guidelines for physical and environmental security as well as the HR security it is not mandatory for an organisation to follow all the guidelines and leaves it up to the organisation to follow it with their convenience and requirement. This means that although a company might be following most of the guidelines of ISO twenty seven thousand two but still might have a security hole which leaves a big question on the ISO twenty seven thousand two standard.

The off-site equipments and the ones that are in transit, if any, should be properly protected and insured (if third party insurance is cost effective) as well as the degree of protection should be proportional to the criticality of the equipment and the sensitivity of the information it carries or can be accessed through it.

“confidentiality or non-disclosure agreement; and/or”

Authorities: ISO-27002:2005 9.2.1.; HIPAA 164.310(c)

Control includes checks that are adequate with the organisation’s trade needs and legal requirements. This should be done taking into account the information that will be accesses and apparent risks. For example in banks criminal and credit checks must be done.

“Maintenance of the physical operating environment in a computer server room is as important as ensuring that paper records are not subject to damage by mould, fire or fading.” This can be done by the use of supporting equipment such as air conditioning plant or mains services.Physical controls also rely on the building structure to some extent which makes it difficult to manage, but still a good physical security policy is always very effective.

3.3 Security Policy

Information concerning the extent of access that the person will have to the business information and their responsibilities under legal-regulatory-certificatory (for example Financial Service Authority for finance).

3.5 Asset Management

Originally, the basis of ISO twenty seven thousand two was a document published by the UK government, which was re-published in one thousand nine hundred ninety five by BSI as BS7799 and became a proper standard. It was again re-published as ISO seventeen thousand seven hundred ninety nine by the ISO in the year two thousand which made it an international standard. Then in 2005, a new version of ISO seventeen thousand seven hundred ninety nine was published by ISO along with a new publication, ISO 27001. The shipments and any other materials that are delivered to the premises should be thoroughly examined and should be separated from the one’s going out of the premises.Authorities: ISO-27002:2005 9.1; HIPAA 164.310(a)(1) To use physical methods to protect the organization’s information and premises from unauthorized access, intentional and unintentional damage and interference.It is extremely important to protect the telecom cables that carry all the sensitive information as well as the power cables that support the information services and other equipment from damage or interception.
