ISO 27001 Implementation Guidelines clause 4.1, this concept would be clear over here through this article etc.
Understanding the organization and its context
The organization determines external and internal issues relevant to its purpose and affecting its ability to realize the intended outcome(s) of the knowledge security management system (ISMS).
As an integral function of the ISMS, the organization continually analyses itself and therefore the world surrounding it. This analysis cares with external and internal issues that in how affect information security and the way information security are often managed, which are relevant to the organization’s objectives.
Analysis of those issues has three purposes:
— Understanding the context so as to make a decision the scope of the ISMS;
— Analyzing the context so as to work out risks and opportunities;
— Ensuring that the ISMS is tailored to changing external and internal issues.
External issues are those outside of the organization’s control. this is often mentioned because the organization’s environment.
Analyzing this environment can include the subsequent aspects:
a) Social and cultural;
b) Political, legal, normative and regulatory;
c) Financial and macroeconomic;
These aspects of the organization’s environment continually present issues that affect information security and the way information security are often managed. The relevant external issues depend upon the organization’s specific priorities and situation.
For example, external issues for a selected organization can include:
a) The legal implications of using an outsourced IT service (legal aspect);
b) Characteristics of the character in terms of possibility of disasters like fire, flood and earthquakes (natural aspect);
c) Technical advances of hacking tools and use of cryptography (technological aspect); and
d) The overall demand for the organization’s services (social, cultural or financial aspects).
e) Internal issues are subject to the organization’s control.
Analyzing the interior issues can include the following aspects:
a) The organization’s culture;
b) Policies, objectives, and therefore the strategies to realize them;
c) Governance, organizational structure, roles and responsibilities;
d) Standards, guidelines and models adopted by the organization;
e) Contractual relationships which will directly affect the organization’s processes included within the scope of the ISMS;
f) Processes and procedures;
g) The capabilities, in terms of resources and knowledge (e.g. capital, time, persons, processes, systems and technologies);
h) Physical infrastructure and environment;
i) Information systems, information flows and deciding processes (both formal and informal);
j) Previous audits and former risk assessment results.
Based on an understanding of the organization’s purpose (e.g. pertaining to its mission statement or business plan) also because the intended outcome(s) of the organization’s ISMS, the organization should:
— Review the external environment to spot relevant external issues; and review the interior aspects to spot relevant internal issues. In order to spot relevant issues, the subsequent question are often asked:
How does a particular category of issues affect information security objectives?
Three samples of internal issues function an illustration by:
Example 1 on governance and organizational structure ; When establishing an ISMS, already existing governance and organizational structures should be taken under consideration . As an example, the organization can model the structure of its ISMS supported the structure of other existing management systems, and may combine common functions, like management review and auditing.
Example 2 on policy, objectives and methods :An analysis of existing policies, objectives and methods , can indicate what the organization intends to realize and the way the knowledge security objectives are often aligned with business objectives to make sure successful outcomes.
Example 3 on information systems and knowledge flows :When determining internal issues, the organization should identify, at a sufficient level of detail, the knowledge flows between its various information systems.
As both the external and therefore the internal issues will change over time, the problems and their influence on the scope, constraints and requirements of the ISMS should be reviewed regularly. Documented information on this activity and its outcome is mandatory only within the form and to the extent that the organization determines as necessary for the effectiveness of its management system.
