Physical access control systems are a type of physical security intended to restrict or enable access to a specific area or building. Often, PACS are installed to secure businesses and property from vandalism, theft, and trespassing, and are particularly useful in facilities that needed larger levels of security and protection.Access controls protect against imprudent access of equipment, data documents, and software. It can restrict physical access, a security system should be able to differentiate between authorized and unauthorized individuals. Physical access can be restricted using three general techniques.Identification − Identification based on comparing the physical traits of the individual with ... Read More

A disaster is described as a sudden misfortune that is disastrous to an undertaking. Natural disasters contains all types of severe weather, which have the potential to pose an essential threat to human health and safety, property, demanding infrastructure, and homeland security.Natural disasters appears both seasonally and without warning, subjecting the nation to frequent time of insecurity, disruption, and monetary loss. These resources serve to prepare IHEs for several natural disasters, such as winter storms, floods, tornados, hurricanes, wildfires, earthquakes, or any combination thereof.There are specific natural disasters can severely damage the computer system directly, or avoid its operations. These ... Read More

A physical threat is a potential cause of an incident that can result in loss or physical harm to the computer systems. Physical security is represented as the security of personnel, hardware, programs, networks, and data from physical situations and events that can support severe losses or harm to an enterprise, departments, or organization. This contains security from fire, natural disasters, robbery, theft, elimination, and terrorism.Physical threat to a computer system can be as an outcome of loss of the entire computer system, damage of hardware, damage to the computer software, theft of the computer system, vandalism, natural disaster including ...

Physical security is an important part of a security plan. It forms the basis for several security efforts, such as data security. Physical security defines the protection of constructing sites and equipment (and all other data and software contained therein) from theft, vandalism, natural disaster, man-made catastrophes, and accidental damage (e.g., from automatic surges, extreme temperatures, and spilled coffee).It needed solid building construction, appropriate emergency preparedness, reliable power supplies, adequate climate control, and appropriate protection from intruders. Risk assessment process recognizes the organization’s vulnerabilities. It can need the vulnerabilities list to set priorities on resources required.Every improvement of an identified ... Read More

Physical security is represented as the security of personnel, hardware, programs, networks, and data from physical situations and events that can support severe losses or harm to an enterprise, agency, or organization. This contains security from fire, natural disasters, robbery, theft, destruction, and terrorism.There are several elements of physical security which are as follows −It can be alternative physical security strategies should be performed. When appropriate, consider the need of window bars, anti-theft cabling (with alarm when cable is disconnected from system), magnetic key cards, and motion detectors.It can be prepared for fire emergencies with suitable automatic non-water fire fighting ...

A risk treatment plan should be recognized for all risks identified. Identified risk can be and is generally managed by several approaches such as Risk transfer, risk avoidance, risk reduction and risk acceptance.Risk Acceptance − Risk acceptance is called by the name of risk retention. It is easily accepting the identified risk without creating any measures to avoid loss or the probability of the risk happening. It contains a decision by management to accept a given risk without more mitigation or transfer, for a period of time.This appears in two classes of circumstances. For risks that are too low to ...

Risk assessments should be conducted by teams that involves both functional managers and information technology administrators. Business operations, workflow, or technologies change, periodic reviews must be conducted to analyze these changes. The result of new threats and vulnerabilities produced by these changes has to be decided. A comprehensive testing of the effectiveness of existing controls also needed.The objective of a risk assessment is to provide management create appropriate strategies and controls for managing of information assets. The basic goals of risk assessment should always be to deal with those elements of decision making that are uncertain.If the results of actions ... Read More

The principle of risk assessment are as follows −The assessment should have clear goals reflecting the informational needs of decision makers and decided in an iterative dialogue between the assessor and the decision-maker.Risk assessment is always connected to decision-making. In specific, it can provide prioritize actions, provide objective and defensible means to distinguish among alternative courses of action, and allows a choice to be made.The scope and content should be depends on the goals of the assessment and best professional judgment, treating the benefits and costs of acquiring more information before undertaking the assessment.The scope of the assessment are as ...

Information security risk assessment is an essential part of enterprises management practices that provides to identify, quantify, and prioritize risks against element for risk acceptance and goals relevant to the organization.Risk management defines a process that includes identification, management, and elimination or reduction of the likelihood of events that can negatively influence the resources of the information system to decrease security risks that potentially have the ability to affect the information system, subject to an acceptable value of protection defines that include a risk analysis, analysis of the “cost-effectiveness” parameter, and selection, construction, and testing of the security subsystem, and ...

Risk analysis defines the review of risks related to the specific action or event. The risk analysis is used to information technology, projects, security issues and some other event where risks can be analysed based on a quantitative and qualitative basis.There are some steps followed by a risk analysis process are as follows −Establish the Risk Assessment Team − The risk assessment team will be answerable for the collection, analysis, and documenting of the assessment results to management. It is essential that some aspects of the activity work flow be defined on the team, such as human resources, administrative processes, ... Read More
