Read the text about incident management and answer each question with NO MORE THAN TWO WORDS from the text Incident management Types of incidents Incidents are generally categorized by low, medium and high priorities. Low$-$priority incidents do not interrupt end users, who typically can complete work despite the issue. Medium$-$priority incidents are issues that affect end users, but the disruption is either slight or brief. High$-$priority incidents, however, are issues that will affect large amounts of end users and prevent the proper functioning of a system. Incidents are classed as hardware, software or security, although a performance issue can often result from any combination of these areas. Software incidents typically include service availability problems or application bugs. Hardware incidents typically include downed or limited resources, network issues or other system outages. Security incidents encompass attempted and active threats intended to compromise or breach data. Unauthorized access to personally identifiable records is a security issue, for example. Roles in incident management IT incident management is normally separated into three tiers of support, generally grouped together in the help or service desk. Most organizations use a support system, such as a ticketing system, for categorization and prioritization of incidents. IT staff responds to each incident according to its prioritization tier. Tier$-$one support typically provides basic$-$tier support or assistance, such as password resets or computer troubleshooting. Tier$-$one support involves incident identification, logging$,$ prioritization and categorization, deciding to escalate to tier$-$two support and incident resolution when appropriate. Tier$-$two support goes through a similar process for more complex issues that need more training, skill or security access to complete. Major incidents are given to tier$-$three support. This category includes incidents that disrupt a business's operation, marked as a high priority, and require an immediate response. Such an example would be an issue with a network that requires an expert or a skilled team to solve. Tier$-$one support involves technical staff that is trained to solve common incidents and fulfill basic service requests. Tier$-$two support includes IT staff with specific knowledge of the system in question. Level$-$three support team members are generally specialists in the subject matter of the incident. For example, a tier$-$three support team could include the chief architect and engineers who work on the product or service's daily operation and maintenance. An incident manager enforces the proper incident response and management processes across the IT support and service delivery team or teams. This person can be involved in the organization's choice of ITSM framework. $1$: What is the priority level of incidents that cause a short service interruption of end users? $2$: Which incidents can lead to a network connection problem? $3$: How many tiers of support are involved in an incident management process? $4$: Who are the members of a tier$-$three support team? $5$: Who can play a role in the selection of a company$$s IT service management framework?
