Socio-political Impact

The SIEM implementers and the related personnel who maintain the operations and security monitoring practices should be able to handle sociopolitical situations.

These people should be well skilled to handle other IT staff to sort out issues normally found to be created, when SOC team raises security incidents.

Chances are that these people get irritated due to the queries they are asked, particularly when the raised incident is a result of an activity conducted by IT staff, and do not indicate any risk.

There should be a clear guidelines for IT staff to declare any such activities beforehand and avoid such embarrassing queries being asked to them by SOC team.

Information security staff should understand the importance of awareness training to the IT staff and such sessions should periodically conducted, and also tested for its being in practice.

It is also important that SOC people should maintain their independence. The Process Flow should clearly be laid down, segregation of duties well defined and not clashing.

The SOC team should be responsible for opening a new case of incident, have rights to re-open the incident but should never be asked for the delay in closure of the incidents. Proper closure of incidents is important and since they should have rights to re-open incidents, their independence would be violated, if they are asked about the delay. This will also violate the requirement of proper segregation of duties.
  

SIEM system health


5. While SIEM is operational, the health of the SIEM system should be regularly monitored.  This can be done by using special health monitoring features in the SIEM.

Note that there could be a better way, it is best to find out the best way of checking system health, quickly and properly, by analyzing pros and cons of each. 

It is seen that the tech people use their skills and knowledge to lay down ways  to monitor system health in a very raw way, the best way should be to use automated tools which continuously monitor system health, could be found even from within SIEM tool itself, and if it isn't there, a third party open source tool can be used for the same, with no additional cost.
