Incident response is an act of addressing and managing the outcome of a security breach or an incident following an organized approach. The objective of applying an incident response is to manage the situation that would limit the incurred damage, as well as reducing costs and recovery time. The incident response includes a policy which helps to serve as a guideline in determining the kind of incident and which provides procedures to be followed to help resolve when an incident occurs.
The computer incident team, security, IT staff, representatives from the legal, human resources and public relations departments make up the organization’s incident response.
SANS (SysAdmin, Audit, Network and Security) Institute, a world-class security operations center, in their experiences in handling computer incidents, they have offered these steps to address an incident effectively.
Doing Professionals The Right Way
Preparing the organization’s users and IT staff by educating them on the importance of security measures and training them how to respond to computer and network security incidents quickly and properly is one of the main task of an organization.
4 Lessons Learned: Professionals
Creating an incident response team is necessary so the group’s task is to determine whether an incident is a security threat and act on it. Once the team finds out that it is a security incident, they get in touch with CERT (Computer Emergency Response Team) Coordination center, which can provide them current updates on viruses and worms and which can track down the internet security activity.
The team continues to determine as to how far has the problem spread over the systems and devices and contains the spreading by disconnecting the affected areas in order to prevent further damage.
When the team validates the origin of the incident, this is followed by eradicating the root cause and all traces of the malicious code.
The team, afterwards, restore the data and software from the clean, backup files, ensuring there are no remaining vulnerabilities, as well as monitoring the systems for signs of a recurrence.
Before the team makes a report on the incident, they analyze first on the incident, so that in the report they reflect on how they handled the incident and what recommendations to give to prevent any recurrence and, at the same time, what to response in case another incident arises.
Creating an incident response team can be effective if the IT staff has the qualification, competence to fill in the role as incident responders and security operations center analysts. For big corporations, security measures are of prime importance such that some corporations would rather outsource from reputed security service providers or contract incident specialists.
In most organizations, it is a mix team up of their in-house incident team in collaboration with an outsourced security analysts. Whatever is the mix up teaming, it is still vital that the organization requires global security standard training of its in-house incident response team from a reputable security provider.
