Information Security management 


What is Information Security management?

Three pillars: [CIA]
  • Confidentiality, 
  • Integrity and 
  • Availability 

Non- Repudiation: 
  • Means cannot be challenged by anybody.
Integrity: of information: 
  • Means unaltered information. Information cannot be changed in-between end to end.
Information processing facility: 
  • Also need to secure the in-between facility which is processing the information. 
Business Continuity:
  • Business Continuity to some extent will be part of the Information Security Management system. And there will be separate Business continuity and Disaster management.
Life cycle of information:
  • How the information should be discarded. 
Other Benefits Information Security Management [ISM] 
  • Reduce Security incidents, increase staff retention, Protection of brand and reputation, reduce costs of correction, customer retention, etc
Background of ISO 27001 / ISO 27002
  • Framework: Sets of Principle, policy’s, rules, guidelines make a whole framework.
Background of ISO 27001 / ISO 27002
  • Framework: Sets of Principle, policy’s, rules, guidelines make a whole framework.
History of ISO 27001 and ISO 27002

  • BSI started in 1901, wanted to start Tube railways and floated in tender. The big problem was getting 5 different plans which had different dimensions. This created the problem that they are not compatible within each other. 
  • BS7799 :1995: - British standards published in 1995 
  • 2005: ISO re- nomenclature and published the 27001 by getting from BS.

Clause 4: Context of the organization

  • What are: - Internal Issue, External issue and Interested parties?
  • Interested parties: Promoters or Shareholders, Employees, Government, neighbours, customers, vendors, etc.
  • Internal issue: When there are internal strikes. 
  • External issue: Government regulatory compliance
  • Here boundaries are set for the rules and boundaries. 
  • e.g.: in Some countries security guards will be present to collect the ID proof and registry entry is made. The same company operating in JAPAN has no security guard. Since there is no practice of security guards in JAPAN.

Information Security management 


What is Information Security management?


Three pillars: Confidentiality, Integrity and Availability [CIA]

Non- Repudiation: 

Means cannot be challenged by anybody.

Integrity: of information: 

Means unaltered information. Information cannot be changed in-between end to end.

Information processing facility: 

Also need to secure the in-between facility which is processing the information. 

Business Continuity:

Business Continuity to some extent will be part of the Information Security Management system. And there will be separate Business continuity and Disaster management.

Life cycle of information:

How the information should be discarded. 

Other Benefits Information Security Management [ISM] 

Reduce Security incidents, increase staff retention, Protection of brand and reputation, reduce costs of correction, customer retention, etc

Activity 2

Why is Information security management important within the organization?

  1. To protect user’s data

  2. To comply with Government Norms

  3. To have control over the data management  

Some information Security facts 

Stats: 

  1. 83% of org see damages to the org reputation as the biggest concern

  2. 93% - had staff related breaches.

  3. 51.6% - reduced security incidents from certified org

  4. 49% - lack of budget to improve Info security

  5. 15% - of small business detected breach

Activity 3

What Needs to be managed in a Information Security Management system?

Data, Physical assets, People Assets, etc

Background of ISO 27001 / ISO 27002

Framework: Sets of Principle, policy’s, rules, guidelines make a whole framework.

Who was Involved in its development?

ISO International Organization for Standardization 

IEC International Electrotechnical Commission

History of ISO 27001 and ISO 27002

BSI started in 1901, wanted to start Tube railways and floated in tender. The big problem was getting 5 different plans which had different dimensions. This created the problem that they are not compatible within each other. 

BS7799 :1995: - British standards published in 1995 

2005: ISO re- nomenclature and published the 27001 by getting from BS. 

Difference b/w to 27001 and 27002:

27001: What has to be done.

27002: How it has to be done: - Implementation guideline:

ISO 27001: 2013

Clause 4: Context of the organization

What are: - Internal Issue, External issue and Interested parties?

Interested parties: Promoters or Shareholders, Employees, Government, neighbours, customers, vendors, etc.

Internal issue: When there are internal strikes. 

External issue: Government regulatory compliance

Here boundaries are set for the rules and boundaries. 

e.g.: in India security guards will be present to collect the ID proof and registry entry is made. The same company operating in JAPAN has no security guard. Since there is no practice of security guards in JAPAN. 

PDCA and ISMS:

DO : implement: - Clause 8 Operation

Check : Audits/ gaps/ managements review: - Clause 9 Performance evaluation

Act : Results/ improvement: - Clause 10 Improvement

DAY 02: May’21


Clause 6 Planning

6.1 Actions to address risks and opportunities

6.1.1 General

6.1.2 Information security risk assessment

6.1.3 Information security risk treatment

6.2 Information security objectives and planning to achieve them


Notes: 

Step 1: Try to identify Information assert

  1. Terms: 

    1. Vulnerability, probability, Risk Assessment, Risk Treatment Plan, Risk Rating, Security Control, Statement of applicability.

  2. Information assert: Try to identify Information assert

  3. Try to quantify the asset, which are high value and low value.

  4. Quantify based on CIA

  5. E.g., Rate the asset based on the scale 1, 2 & 3 to create asset value. 

  6. E.g., Formula for asset value; like: C + I + A = asset value

  7. E.g., Confidentiality: when assert is public scale is 1


Public

Step 2: Risk identification/ analysis

  1. Risk rating associated with the assert value

  2. Probability with risk rating

  3. How the Vulnerability is the probability increases.

  4. For every risk there can be any opportunity.

Step 3: Risk Treatment Plan [RTP]

  1. Risk Avoid or termination, Risk Accept, Risk Share or transfer

  2. Risk Transfer: 

    1. E.g., Cell phone tower: where there will be backup generators -the diesel will be stolen or wastage. They transferred to vendors to look into the DC backups.

  3. Risk Treatment:

    1. Lowering the risk / means reducing the Vulnerability

  4. Threat and Vulnerability

    1. Threat: earthquakes are threat; hackers are threat

    2. Vulnerability are gaps in the system, through which problem can arise. 

  5. Residual risk:

    1. Left over risk and risk owner must be identified for residual risk

ISMS Manager: Risk treatment

  1. When Mitigation plan is implemented and lowering the risk probability 

  1. Risk owner is equal to asset owner

RTP: have to lower the risk from higher risk

Leadership = guidance’s [leadership are Born]

Management = controls [Mangers are created]


Change management


Kotter’s 8 Steps to successful change. 

1) Increase urgency - inspire people to move, make objectives real and relevant.

2) Build the guiding team - get the right people in place with the right emotional

commitment, and the right mix of skills and levels.

3) Get the vision right - get the team to establish a simple vision and strategy, focus on

emotional and creative aspects necessary to drive service and efficiency.

4) Communicate for buy-in - Involve as many people as possible, communicate the

essentials, simply, and to appeal and respond to people's needs. De-clutter

communications - make technology work for you rather than against.

5) Empower action - Remove obstacles, enable constructive feedback and lots of support

from leaders - reward and recognise progress and achievements.

6) Create short-term wins - Set aims that are easy to achieve - in bite-size chunks.

Manageable numbers of initiatives. Finish current stages before starting new ones.

7) Don't let up - Foster and encourage determination and persistence – on-going change -

encourage on-going progress reporting - highlight achieved and future milestones.

8) Make change stick - Reinforce the value of successful change via recruitment,

promotion, new change leaders. Weave change into culture.


Example:

  1. Confidentiality and Integrity: the balance sheet will be confidence till published to public. Once published Integrity becomes High and confidentiality becomes zero.

  2. Controls are required to reduce the RISK.
