Description
SOC is abbreviated as Security Operations Center,
a centralized team of any company that monitors
real-time threats, real-time incidents, and
suspicious activities. The SOC team will take the
appropriate action or assign some professionals
to handle the risk if found. Any organization
hires a SOC team for two primary reasons. First,
the SOC team makes sure that the impact of an
already-happening compromise or incident will be
minimal. For example, if one of the
systems/computers has been compromised, the SOC
team must ensure the remaining computers work
correctly. Second, they must make sure that the
cost of remediation is minimal. So if you are
also willing to become a SOC Analyst and are
preparing for interviews, these hand-picked
interview questions may help you. Have a look.
