Scope

Dear Friends welcome back. Thanks for all the positive responses and likes that motivates me to write better than my previous article. Today we will try to understand how to decide and write the scope of any audit or implementation of ISMS.

Scope describe the extent and boundaries of the audit or implementation in terms of factors such as physical locations, organizational units, activities and process to be audited, where relevant, the time-period covered by the audit.

According to my understanding we can define the following format to write the scope of any audit or implementation:-

· Objective :- We will 1st define our objective (try to make it short and simple not more than two lines)

· Boundary or Requirement: – Over here we will set out boundaries (for example if the company where we have to implement ISMS have 12 departments but we only want to include 8 of them, then we will mention those 5 departments names here).

· Extent :- the last thing will be the extent to which we will go to achieve the above mentioned objective.

Now before going into any technicality let’s try to understand the scope with day to day activities. For example if I have to decide the scope of going to office, then it’s involves:-

1. Objective:-

a) Reaching office

2. Boundary:-

a) Reaching Office before 9:30am (Race against the time)

boss-yelling-at-employee

b) Stay Alive (tug of war @Mumbai Local) so to survive I always prefer slow local starting from my source station

mumbai-local-train

3. Extent

a) If I will be late then I can catch a fast local.

b) I can go by bus if due to some reason local is not available.

Many will feel that we can book a cab and reached office on time, but as I mentioned above that we are talking about my scope of reaching office on time, so my pocket doesn’t allow me to go to office by cab and hence I will prefer to be late as compare to booking a cab and then reaching office on time.

So, the boundary for me reaching office is the timeline (i.e., 9:30am) and the extent is that I have to reach office is the mode of transportation.

Now we will try to decide the scope of implementation of ISMS within an organization which deals in software development and who have offices across the country:-

1. Objective :- The objective will be implementation of ISMS within the organization

2. Boundary / Requirement: – We will define the boundary of our implementation. For example if we have 5 dept. within our organization i.e.,

a. IT Support

b. Development Team

c. Database Team

d. Network Team

e. Admin

Out of above mentioned 5 teams I don’t want my admin team to comply with ISMS so I can keep Admin team out of the boundary of my scope. So, our boundary within the organization will be IT Support, Development Team, Database Team and Network Team.

3. Extent: – We can define the extent as all the offices in country or if management wants to go with a particular region (for example Northern Region), then the extent of our implementation will be all the offices in northern region.

We shall always keep few things in mind while defining the scope:-

· It shall be short and precise

· Boundaries shall be well defined

· Extent shall be clearly defined

· There shall be a proper approval of defined scope from the senior management

Basics of ISMS

What is ISMS?

ISMS stand for Information Security Management System, as we can see it’s a combination of four words. So, before going in depth about ISMS we need to understand these words.

Information , according to Wikipedia “Information is a sequence of symbols that can be interpreted as a message”. Let’s try to make it simpler, information is a collection of data which will help us in taking decisions or identifying something. For e.g.: – If I give you 3 words i.e., “Mr. A”, “train” and “7:30 am”, what information you can derive from this. Let’s consider three situations which can be derived from these words:-

1. Mr. A has to catch a train at 7:30 am.

2. Mr. A missed 7:30am train.

3. Mr. A will not travel by 7:30 am train, etc.,

We can easily figure out, if I would share any one of the above possibilities instead of just mentioning 3 words then it will be easy to identify someone or make a decision.

Security means safeguarding information which is valuable. Always remember for any company people (which mean us are most important). That doesn’t mean that in ISMS we will talk only about securing us but it’s also involves securing people, process (both IT and Non-IT) and technology.

We can now define information security as safeguarding information which is valuable to any organization. There is triad of information security as shown in Fig.1 and define below:-

Figure 1

1. Confidentiality:- Only the legitimate user have access to information.

2. Integrity:- Only Legitimate user can make changes in any information.

3. Availability: – Information should be available for legitimate user when needed.

Management is the task of achieving any objective in the most effective and efficient way.

System is an approach to perform an overall activity or duty or solving a problem.

We can define ISMS as a management system to secure information from unauthorized disclosure or manipulation in most effective and efficient way so, as to achieve business objective or goal.

One point to remember is that information security is not all about IT security. It involves both the IT and Non-IT Security as well as can be implemented on soft and hard copy information.

What is ISO 27001?

Although every company is taking due care to safeguard all the information within their organization but there is not formulated set of procedure to do so before October 2005. In 2005, International Organization for Standardization and International Electrotechnical Commission published the ISO 27001 which is a part of ISO 27000 family of standards. Its full name is ISO/IEC 27001:2005 – Information technology — Security techniques — Information security management systems — Requirements. ISO 27001 was updated in 2013 and require the management to perform the following activities:-

1. Thoroughly scrutinizing the organization’s information security risks, considering the threats, vulnerabilities, and impact

2. Designing and implementing a complete and lucid collection of information security controls to encounter risks.

3. To ensure the continual improvement in the system for enhancing information security.

ISO 27001 is a standard which talk about continual improvement with the help of the cycle mention below or can use any other reference model to showcase continual improvement in the Fig. 2

Figure 2

ISO 27001 has 14 Domains and 144 controls. All the controls are well explained in ISO 27002.

Who does ISO27001 apply to?

Any organization (small or big) can comply with ISO 27001 especially where there is a flow or storage of critical information either in soft copy or hard copy. The best part of ISO 27001 is that it’s not stringent like some of other security standards hence it’s not mandatory for any organization to comply with all the 144 controls. But it’s also doesn’t mean that you will select the controls depending about your feasibility and convenience. For any exclusion you have to justify it with proper reasoning.

ISO 27001 Benefits

1. An advantage over competitors.

2. A framework for complying with all the legal and regulatory requirements.

3. A continual improvement process, hence reducing security incident.

4. Pro-active process.

In this section I will talk about the effectiveness of various cybersecurity control controls (like BYOD, Cloud etc.) .  I will also discuss the procedure of conducting the Opening and Closing meeting as well as disclosing the findings of Audits Procedure in front of auditee.

In the first article we will discuss about the Cloud Security which is the most upcoming topic in the current time.

Cloud computing security or, more simply, cloud security refers to a broad set of policies, technologies, applications, and controls utilized to protect virtualized IP, data, applications, services, and the associated infrastructure of cloud computing. It is a sub-domain of computer security, network security, and, more broadly, information security.

Cloud security architecture is effective only if the correct defensive implementations are in place. An efficient cloud security architecture should recognize the issues that will arise with security management. The security management addresses these issues with security controls. These controls are put in place to safeguard any weaknesses in the system and reduce the effect of an attack. While there are many types of controls behind a cloud security architecture, they can usually be found in one of the following categories:

Deterrent controls

These controls are intended to reduce attacks on a cloud system. Much like a warning sign on a fence or a property, deterrent controls typically reduce the threat level by informing potential attackers that there will be adverse consequences for them if they proceed. (Some consider them a subset of preventive controls.)

Preventive controls

Preventive controls strengthen the system against incidents, generally by reducing if not actually eliminating vulnerabilities. Strong authentication of cloud users, for instance, makes it less likely that unauthorized users can access cloud systems, and more likely that cloud users are positively identified.

Detective controls

Detective controls are intended to detect and react appropriately to any incidents that occur. In the event of an attack, a detective control will signal the preventative or corrective controls to address the issue. System and network security monitoring, including intrusion detection and prevention arrangements, are typically employed to detect attacks on cloud systems and the supporting communications infrastructure.

Corrective controls

Corrective controls reduce the consequences of an incident, normally by limiting the damage. They come into effect during or after an incident. Restoring system backups in order to rebuild a compromised system is an example of a corrective control.

Please keep on visited the site as i will update the framework assessment sheet as and when required.

In this section I will cover the implementation of ISMS. I will start this section with the Gap Analysis and then will cover all the 14 domains and 144 controls implementation of ISO 27001 in the best possible way. This part will also deal with the actual auditing procedure and guidelines.

This section of my blog will be dedicated to all the basic definition and process involve in ISMS implementation or Sustenance Activities. I will also be discussing about the basics of audit procedure. Standards related to Information Security and new methodology introduce in terms of ISMS compliance.

Hello World!!

Hello friends!!!!!!

Welcome to ismsworld.wordpress.com! When I entered in the corporate world of Information Security , I came across so many situation when during a conversation on a project with my colleagues I realize the terminology they are using I am not at all aware about it. Those are really bad situations as you want to make an impact also but you have no idea what they are discussing about. So, you stay there numb and try to act as you know everything and you agree whatever they say. After that you Google it also but after spending hours, you will not come across anything. Now, when I knew something about our lovely ISMS, I decided to start this blog to support the fresher’s and professionals like us who at times missed out few thing due to work load or pressure or use of some big corporate jargon’s.

I am not an expert in this field; I will be sharing my experiences and my understanding of ISMS with you all. So, if you find something which can be done in a more effective and efficient way then what I mentioned on this blog then feels free to comment on that post. I want this process to be a two way learning process. Everyone is most welcome to post your queries and I will try to answer your queries ASAP.

I will also take this opportunity to thanks bunch of people and I will mention their names as I want to tell them that I love them all and without them I would have not be where I am today – Atin Bhaiya & Achlesha Bhabhi (for been a great guide),  Ajay Nehra / Naveen (Alias Chahca) / Pariskhit/ Vidit Shrivastava / Vivek Sharma (Alias Kali) – My biggest critics,  Mahima & Sanjay (Best Siblings one can have),  Anant Rai (Alias Zihadi – without his Zihad I would have not learned so much), Deepesh Bharat Shah (Contributor to blog),  all my friends, my batch mates (from BHS, SBCET, IIIT-A) and colleagues (from Tryst, MG techno Savvy, MIT, NII and Mahindra SSG, Aujas, Paramount Computer Systems).

Lastly I want to thanks the five most important people of my life, who is always there to support me in all situations and always believe in me – My Mom, My Mother-in-Law, My Dad, My Dad in law and My Big B (Ankur Kumar Shrivastava – My biggest Strength), Love you all.

Biggest thanks and lots of love to Bhumika Kaushal (My partner in crime) !

Special Love to future generation Rudra, Ena & Myra !!

Let’s begin our ISMS Journey. All our Welcome!!!!!!!!!
