The organization’s information
system depends on the successful operation of many inter-dependent support
systems including, power grids. Power irregularities issues are dramatically
affecting the availability of information and systems.
Loss of power (blackout) or
instability (such as spike, surge, sag, brownout, or fault) has negative
impacts on the information availability. Devices that rely on electricity
(including as computers, servers, router, firewalls, and IDSs) in organizations
are vulnerable to instability as a
result of these changes.
1. What are the Countermeasures to prevent these threats to
happen?
2. What are the Responses to deal (reduce, stop) with the threat
when the threat takes place?
Countermeasures:
1-
Regular maintenance for the
generator: every organization should make a contract
with companies who provide a regular maintenance for its internal generator
like (Olayan and Khayrat Al Khaleej for Energy companies) in order to fix any
errors that might cause blackout. (Razan)
2-
Full-company Hybrid: Solar + Batteries +
Generator: this strategy state that the organizations use three sources for
energy at the same time. The main source of energy is the generator but if any
error happened to it, that cause reduce in its power the other two sources
(solar energy and batteries) will automatically provide power equal to witch it
was reduced. In this way no power instability will happened. (Razan)
3- Use wind as an electric system: to support the main generator and reduce
the pressure from it. If enough wind resource is available in the area and the
situation is right, small wind electric systems are cost-effective renewable
energy systems. It can be done using turbines or towers. (Kenda
4- Try not to Use Electricity When Not Using It (when not in
need): For example people tend to leave things
plugged in for hours or maybe even days between the times they actually use
them. This includes computers, light bulbs, our air conditioning or heating
(when we are out), coffee machines, and much more. These things are then using
electricity even when not using them. This may lead to instability. Simply
unplug these things when not going to use them. (And, in the case of the AC or
heating, turn it off when going to be out for a while.) (Kenda)
5-Use The Voltage regulator module that
provides fixed voltage to the hardware when there is instability (Brownout or Surge)
in the electricity voltage that will affect the performance of the hardware
devices and may cause to lose data if the hardware fails due to the electrical
instability. (Norah)
6- Use The UPS power supplier for the
critical servers and hardware that contains data need to be saved, to recover
them and continue the business operation by making the power generators ready in
case a blackout or any issue stems from electrical instability in the company.
(Norah)
Responses:
1 - Use
external generator for backup: Every company must have its own external generator to use in case of
blackout. The power of the generator depend on the size of the company (the
more the company is big more power its need), most of the company need at least
generator who are able to provide electricity for (5-8) hours.
During the blackout the company will back up all its systems. Also, it’s a good
idea for the companies to program its systems to be backup automatically every
30min so no information will be lost and it won’t take much time to back up
through the blackout. (Razan)
2 -
Contact
with the electricity company: the company must send a request to the
electricity company to send them a technician to solve the problem. This
process should be the first response that the company do, because in some cases
the problem can be solved at the same time from the electricity company so
their would be no need to make other responses. (Razan)
3 -
Turn off all the machines and devices that may get damaged if the
electricity came back suddenly. The voltage may vary and damage any devices
that are on. Also set all equipment and appliance switches to the OFF position.
In order to protect when the full surge or current hits as the power comes back
on. (Kenda)
4 -
Demand response: is a program that can be
administrated by several organizations including energy providers and pays you
for committing to reduce electricity usage during periods of peak demand across
the system. It can also be defined as: "a wide range of actions which can
be taken at the customer side of the electricity meter in response to
particular conditions within the electricity system (such as peak period network
congestion or high prices)”. (Kenda)
5 -
Discovering
the source of the blackout by the organization's maintenance staff and check if
it is limited or wide-range area is a main step after contact the electricity
company. Determining the problem helps you to fix it immediately, get better
resources to prevent the risk from happening again, or even set new regulations
and policies in the future to minimize the likelihood and impact of electrical
instability. (Norah)
6 - Save
the work and data on the server and shut it down manually to avoid any damage
that could happen to the server or any hardware due to the electrical surge
when electricity restored. (Norah)
