Savvy|Smart|Sexy People Do NETWORK SECURITY ASSESSMENT :)

An evaluation target (TOE) that provides security (a combination of confidentiality, integrity and availability) must have characteristics of appropriate security. It will normally be necessary to determine that a degree of appropriate confidence can be given to these characteristics. For this, the characteristics themselves must be specified. The document (s) that specify these characteristics, as well as the desired level of evaluation,security target for this TOE.

In these criteria, the safety characteristics are considered to be three level. The most abstract point of view is that of the safety objectives which represent the security contribution that a TOE proposes to make. For to achieve these objectives, the TOE shall contain certain functions dedicated to the security. These security enforcing functions must, in turn, be implemented through specific security mechanisms. These three levels can be schematized as follows.

Security objectives-why functionality is wanted.

Security mechanisms-how functionality is provided.

Security target

The security target serves both as a specification of the security enforcing functions,in relation to which the TOE will be assessed, and a description of the links between the TOE and the environment in which it will operate. Are therefore interested in the security target not only those responsible for the production of the TOE and its evaluation, but also those responsible for its management, for its purchase, for its installation, configuration, operation and employment.

The required content of a security target may be summarized as follows: 

either a system security policy

a product rationale.

FUNCTIONALITY

a specification of the required security enforcing functions.

a definition of the required security mechanisms (optional).

the announced rating of the minimum strength of the mechanisms.

the level of assessment.

Each of these elements is described in more detail below.

Security target presentation requirements depend on the level evaluation. The level of evaluation also determines the other documents of the TOE which must be provided for the evaluation, as well as the requirements on their content and format, and requirements for evidence that shall be provided to show that the TOE meets the security target.The security target may be in the form of a single document or a number of documents. When several documents are used, their relationships must be clearly indicated.

The valuation sponsor is responsible for the supply and Fidelity security target for evaluation.

System security policy

The components constituting a security target differ according to whether it is a system or product. In the case of a system, the actual environment in which the TOE will be used is known, its security objectives can be determined, and actual threats and existing countermeasures may be taken into account.These details are provided in a system security policy document.The security policy of a system specifies all laws, regulations and practices governing how to manage, protect and disseminate information and other sensitive resources within a specific system. It must identify the security objectives of the system and the threats it will face.

These safety objectives must be taken into account by a combination of system security enforcing functions (implemented within the TOE), and also by physical, personnel or organisational means,associated with the system. The security policy of a system must cover all security aspects of the system, including these physical measures,

Staff and organisational matters.

 All organizations will have general safety standards that will apply systems within the organization that will define the relationships security between the organization and the outside world. These standards can be considered as an internal security policy: All the legislation, regulations and practices governing how to manage, protect and disseminate property, in particular the sensitive information within the organization. Many organizations will have an explicit and written internal security policy, which specify national and international rules, practices and laws they must comply with. In that case, we have to do reference in the system security policy. Otherwise, all relevant aspects must be presented in writing in each of the policies of Organization Systems Security.

The Secrets To NETWORK SECURITY ASSESSMENT

In just 40 years, information Technology (it) has come to be play an important and often vital role in almost all sectors of society organize. As a result, Safety has become an essential aspect of the

Information technology.

IT security is characterized by :

confidentiality-prevention of unauthorized disclosure of information ;

availability-prevention of unauthorized denial of access to information, or resources.

An IT system or IT product (based on Information Technology) will have its specific requirements to maintain confidentiality, integrity and availability.To satisfy these requirements, it will implement a number of measures security techniques, referred to in this document as security enforcing functions,that covers for example areas such as access control, audit and incident recovery. Confidence in the compliance of the security enforcing functions (both at the view of their development and that of their exploitation) or of the trust the effectiveness of these functions.

System users must be able to rely on the security of the systems they use.They also need a yardstick against which to compare skills in security, IT products they plan to buy. Although they have the ability to rely on input from manufacturers or suppliers of systems and the products in question, either to test them themselves, it is likely that many will prefer to rely on the results of an impartial evaluation carried out by an independent body. Such an evaluation of a system or a product requires well-defined and objective safety assessment criteria the existence of a certification body that can confirm that the evaluation was conducted properly. System security targets are specific to the particular needs of the users of the system in question, while that product safety targets are more general, so that products that meet these targets can be incorporated into many systems with similar but not necessarily identical safety requirements.

INTRODUCTION 

The Term IT System is often used to describe this procedure. It requires consider many factors before considering that the system suitable for the intended use: it requires the security assurance provided by the system, the confirmation of Security administration responsibilities, the compliance with technical, legal or regulatory requirements regulatory confidence in the adequacy of other non-technical measures security provided by the system environment. The criteria contained in the this document is primarily concerned with technical safety measures.,but take into account certain non-technical aspects, such as the safe operation for personnel, physical and organizational security (but only when they encroach on measures technical security).

Much work has already been done to develop evaluation criteria IT security, despite some slight differences in objectives according to the specific requirements of the countries or bodies concerned. Most important,and in many ways a precursor to other work, was the document Trusted

Computer System Evaluation Criteria [TCSEC], commonly known as TCSEC or "Orange Book" (Livre orange) which was published and used by the defense of the United States for product evaluation. Other countries, mainly European, also have significant experience in the evaluation of the IT security and have developed their own IT security criteria. TheUnited Kingdom, this is the case of the CESG memorandum number 3 [CESG3] developed at government usage, and proposals from the Ministry of trade and industry in the 'Green Paper' [DTIEC] for the commercial products of IT security. In Germany, the German Information Security service has published a first version of its own criteria in 1989 [ZSIEC], and at the same time at the time criteria were developed in France under the name of the "Livre bleu-blancrouge" [SCSSI].Now a days it become more popular around the world.

The Secret of DATA CENTER CONSULTING

Energy costs continue to increase, a trend that will continue in the future, while broadband penetration allows the introduction of new active equipment to the network architecture.

In this context, it is vital that the main ICT players (ICT users) implement effective general engineering of fixed and mobile broadband networks with associated operator sites (including data centers). This is to answer the essential questions of energy consumption while proposing essential solutions for the deployment of "true" broadband. To guide this process, it is essential that the parameters are defined, called Key Performance Indicators (KPIs worldwide) that monitor and control the energy efficiency of Data Centers and associated Telecom equipment.

Data centers are true computer production factories and as such faithfully reflect our consumption patterns and ever-increasing energy needs.The consumption of computer centers has increased by 20% per year for the last 5 years.

3 to 5% annual growth for the cost of energy over the next 5 years in different countries.Between 2005 and 2010, the additional power related to Data Centers only represents 10 * 1000MW, the equivalent of about 10 nuclear reactors. A data center of 10,000m2 consumes as much as a city of 50,000 inhabitants 20 times more power cuts on data centers in 2009.

In 2007, IT generated 2% of  gas emissions.

The "farms" of computer servers consume 7% of electricity in France, seven times more than in 2005. The operational operating time of a datacenter is about 3 times faster than the time required to ERDF to build a source post.

Reducing costs, improving flexibility, and increasing business agility require applying process optimization methods at the Data Center level to account for:

Business changes that require dynamic infrastructure to meet customer needs.

Virtualization that allows switching loads significantly.

The increase in energy consumption when new systems are put online and existing unused servers remain connected.

Unclear relationships and dependencies on system components, applications, and divisions that make it more difficult to respond to change and change requests.

The size and complexity of Data Centers increases as the business grows, posing challenges even for seasoned professionals in making decisions to improve day-to-day operations.

The cost of powering a Data Center exceeds the costs per square meter, and managers need to know the power consumption for each equipment and bay to better control these costs.

Aging servers that are less efficient in terms of energy saving process the data to their maximum capacity, and all the assets of a rack regularly exceed the available power capacity. Unless you know the power requirements of these assets, it is impossible to redistribute all these assets to optimize the data center, as well as carefully plan the addition of new assets for successful operations. Data center administration and planning tools in the form of static files are no match for the need to discover and dynamically allocate datacenter hardware to work optimally.

If there is no standard method for viewing assets and related information, including their relationship to other components and financial and contractual details, a company faces unnecessary risk.

The need to coordinate IT developments with operational constraints and energy costs is a new subject that requires new tools.

The ratios presented below appear then as the minimum to know then to master the energy evolution of its DATA CENTER.

The main indicators

PUE for Power Usage Effectiveness is the most well-known indicator of Data Center managers. It is the opposite of the DCIE (expressed in%) recognized by the European Union as the reference indicator for measuring the energy efficiency of a Datacenter. These 2 indicators have the same meaning.

The CPUE should not remain the sole indicator of energy management of a data center.

The CPUE is a value that must be appreciated over a year. Above all, it allows the global evolution of energy consumption to be monitored over a period long enough to be relevant.

There are other indicators, much less known, that can provide the manager with valuable information on the method and priorities of actions to be implemented to increase its efficiency. For example:

The EUDP, an operational steering indicator whose calculation formula is identical to that of the CPUE but applied to a separate and representative area of ​​the Datacenter. It can be for example:

A blade server zone,

A mainframe zone,

A storage area,

Telecom zone,

The IEEI, is the ratio of the total power of the room on the power of computing, measured continuously. the IEEI is then averaged hour by hour, so it represents values ​​identical to the PUE but in average hourly power.

The Reference Profile represents the optimum energy efficiency of the Computer Center. It is the one for which it was built vis-à-vis the technical infrastructures invested. It should be the operational target on which the site must be operated and maintained.

The Reference Profile is calculated on the typology of the technical infrastructures as built and the specifications of the equipment that constitutes them. It is the 3D representation of a surface establishing the level of the minimum intrinsic CPUE according to the two main variables that characterize it and which are:

Outside temperature (within the meteorological limits of the site)

the IT power load of the room (from 10% to 100%)

Reference Profile Example:

This Reference Profile, combined with local weather data, is used to determine the objective target PUE. It allows the identification of the various probable CPUE of exploitation according to the different IT charge rates and these meteorological data.

Other indicators can be representative and interesting to calculate:

CUE to measure the volume of greenhouse gases;

ERF to measure the amount of energy reused outside the data center

GEC for renewable energy share

The objective is not to multiply the calculations but to know how to determine the right indicators according to a well-defined strategy. ( Energy Master Plan ).

You Don't Have To Be A Big Corporation To Start MANAGED IT SUPPORT SERVICES

It is important to note that the transition from performance-based to value-flow-based cost distribution cannot - or should - happen overnight. The entire organization must first have embraced the new approach and there must be a free and open flow of data between the work teams if the cost distribution is to be consistent. That being said, there are some steps to follow along the way:

Step 1: Check the customers

A company that understands what creates added value for its customers is best placed to work out processes that can deliver this. Each step in the value flow should be developed with the same focus and coordinated for maximum productivity. This applies to everything from marketing activities, warehousing and delivery tactics to manufacturing strategies.

Step 2: Find the weakest link

Just as with all processes, the value flow is never stronger than its weakest link. The road to significant productivity gains is about discovering bottlenecks early in the process, so that you can build systems to avoid them and give the staff the right conditions to work more productively. The availability of business data at a detailed level is very important during this early stage and in the Supply Chain world we have experienced that companies have succeeded in raising productivity by 20 percent from one year to another.

Step 3: Digitize the processes

It may seem obvious to point out that managing digital processes is easier and faster - not to mention the fact that they can easily be automated to increase the work rate throughout the business. When you add new data from sensors and new forms of automation in the compote, the flow of flow managers is provided with more information than ever before. The information can be used to fine-tune strategies and work preventive to circumvent any obstacles.

A discovery and repaired bottleneck can have a major impact on the company's results

With the risk of the metaphor becoming worn out, I would like to return to the king's lax's arduous journey uphill. The difference between life and death is often a matter of centimeters and ultimately deals with how much energy a fish has saved to cope with each obstacle (plus some luck of course). In a large organization, the smallest snort in a bottleneck in production can lift a product from the cost center to a factor that alters the entire playing field. What companies need is the right employees, strategies and infrastructure in place to discover and sort out these nodes when they appear.
