This system is typically influenced by organization's needs, objectives, security requirements, size, and processes.

Information security management system Īn information security management system (ISMS) represents the collation of all the interrelated/interacting information security elements of an organization so as to ensure policies, procedures, and objectives can be created, implemented, communicated, and evaluated to better guarantee an organization's overall information security. The threat of user apathy toward security policies (the user domain) will require a much different mitigation plan than one used to limit the threat of unauthorized probing and scanning of a network (the LAN-to-WAN domain). The mitigation method chosen largely depends on which of the seven information technology (IT) domains the threat and/or vulnerability resides in. Once a threat and/or vulnerability has been identified and assessed as having sufficient impact/likelihood to information assets, a mitigation plan can be enacted. Mitigation: The proposed method(s) for minimizing the impact and likelihood of potential threats and vulnerabilities.Impact and likelihood: The magnitude of potential damage to information assets from threats and vulnerabilities and how serious of a risk they pose to the assets cost–benefit analysis may also be part of the impact assessment or separate from it.Vulnerabilities: How susceptible information assets and associated controls are to exploitation by one or more threats.Threats: Unwanted events that could cause the deliberate or accidental loss, damage, or misuse of information assets.A meteorite crashing into a server room is certainly a threat, for example, but an information security officer will likely put little effort into preparing for such a threat.Īfter appropriate asset identification and valuation has occurred, risk management and mitigation of risks to those assets involves the analysis of the following issues:

Managing information security in essence means managing and mitigating the various threats and vulnerabilities to assets, while at the same time balancing the management effort expended on potential threats and vulnerabilities by gauging the probability of them actually occurring.

2 Implementation and education strategy components.1.1 Information security management system.To protect against cyber threats while staying compliant, organizations turns to SIEM solutions to DISCOVER, PROTECT, DETECT and CORRECT incidents within the network environment. It combines Security Information Management (SIM) and Security Event Management (SEM) to provide real-time analysis of security alerts generate by network hardware and applications. Security information and event management (SIEM) is an approach to security management that seeks to provide a holistic view of an organization’s Information Technology (IT) security.
