It is crucial to have a network disaster recovery plan for organizations as a means of prior preparations in the event disruptions occur that affect the corporates local area network, any internet access, wide area network and other services provided by the wireless network. This can be as result of humans with malicious intent or uncontrolled natural disasters. Making a network disaster recovery plan will allow preparations that will facilitate the restoration process of the integrity of the network in order to return to the normal daily operations within the shortest time limit possible. Its essential for all company locations that are connected to the wide area network to implement security measures often and keep them updated. This will prevent the chances of any potentially unplanned disruptions that might hinder normal operations or enable quick and rapid network recovery in case an incident occurs. Having a network disaster recovery plan eliminates any possible errors that might be caused due to confusion by allocating different teams to attend to their allocated responsibilities during a disaster. The plan reduces the damage that results from disrupted corporate operations by the tactical team offering another alternative network while addressing the disruption. Relying on particular key individuals who might not be disposable over a disaster is also avoided by selecting a group of specialists who know exactly what to do in the event of a disaster. Also, a network disaster recovery plan helps in safeguarding the company’s data and maintaining its integrity.
In the event there is a sudden internet outage, the leading network administrator should start by identifying and assessing the internet outage. The lead network admin should then review this occurrence with the IT management team since the lead network admin is the network operations director. After reviewing the outage, initiating the remedy actions in order to recover or reinstate the network assets is done by a particular assigned specialist or the lead network admin. The decision to start the network data recovery plan is made by the director of all internet and network operations. After deciding, the designee is the one responsible for the activities entailed in the network data recovery plan and making contact with any appropriate carrier or vendor. The network administration team ensures all the network recovery procedures are followed through and a report is written by the designee to the senior management of IT giving insight on all occurrences done.
In the event that a malware has attacked the computers in the organization’s network, the best steps to take and safeguard and prevent further damage include disconnecting and isolation. The assigned specialist or lead network admin should identify and asses the attack to determine the extent to which the attack is before isolating the victimized computers and prevent any further spreading. Any suspected computers should be disconnected and treated as if infected. After stopping any further spread of the virus, the main focus should now be cleaning up where the specialist removes the malicious code using specific tools such as an updated antivirus software. After cleaning up and updating security, the next smart course of action is to reinstall the operating system since most virus attacks change file names or end up disabling some software features permanently. After reinstallation, the lost data can now be recovered from backed up files either locally or on the cloud. After restoration it is important to check for any potential threats by scanning and in order to prevent any future possible attacks, keep the antivirus updated at all times.
When there isn’t any network in the local area network, diagnosing whether there is a physical hardware failure or some communication protocols have been affected is important. The lead network admin or the assigned specialist should start detecting in order to determine what the problem is. For hardware failure, the devices used to switch the network could be broken or disconnected or the data and fibre cables are faulty or disconnected. In order to verify whether the communication protocol stacks don’t have an issue, the lead network admin or assigned expert should examine the layered network protocol using the TCP/IP reference model.
While the analysis and detecting are in progress, the lead network admin should advice other workers to switch to the wireless network. Another possible cause of network outage in the local area network could be a virus attack on the central computer in the channel that controls the whole network. Diagnosing the computers in the main channel can be done by detaching and attaching any connected devices individually in order to determine what and where the problem is. If al the stacks in the communication protocol are ok, the lead network administrator should consider restarting or resetting the system as a whole as a possible remedy.
The network admin should first assess and determine the computers that do not have internet access and proceed to advise the employees to switch from local area network to wireless and vice versa when the wireless internet is not working. Switching ensures no normal daily operations are interrupted during the diagnosis of defective devices and other equipment’s period. After performing tests and determining what devices are faulty, they should be immediately repaired or replaced. Given that only a part of the company network id down, the affected area only should be disconnected before being fixed to avoid any chances of affecting the other areas of the company network that are functioning alright. Incase the data in the affected area was not yet backed up to the cloud or the central servers, this should be performed to avoid more loses from occurring. There are a number of reasons that might result to the network access shortage partly in a network. They include starving the network switches of power supply causing them to not relay the network to the entire channel. However, this has to be affirmed by the assigned specialist through running a diagnostics test among other tests before being able to implement counter measures.
The network administrator should ensure uninterrupted power supplies are already installed to enable users to have a time to save their work as soon as there are power outages. However, the permanent solution and remedy to avoid any damages that can be done by power outages, the company should invest in installing a backup generator that provides power during outages. The department of IT should regularly check the operation of the installed uninterrupted power supply and if any one of them is faulty, it should be replaced immediately. Having a backup source of power such as solar energy or powerful self-detecting automatic generators could also remedy power outages by providing the required power.
The network administrator upon knowledge of a password breach should immediately shut down the power system in order to prevent the individual with malicious intent from copying and data from the company or messing with its integrity in any way. After preventing any data loss by shutting down, the next step should be to change all passwords and ensure they are strong passwords according to the required standards. The IT department as a precaution for future event such as those, should think about implementing other security verification techniques such as using work email verification method, biometric, phones or using a security card verification system.
The main precaution plans that can be implemented include setting up the uninterrupted power supplies and automatic power generators or solar panels for power outages. For internet outages, both wireless and local area networks should be operational at all times so as to provide an alternative when one internet source is down. Data should also be regularly backed up on the cloud and the other servers.
The client might be interested in knowing whether the company stores all the data about the transactions and other business dealing that go on between the company and customers. The constant data backing techniques implemented in the cloud and other central servers should be evidence enough to give a response.
