Some Causes of Network Failure
Downtime caused by network problems has a major impact on the business.
- Incorrect configuration - is the cause of about 80% of unplanned outages. Incorrect assignment of ip, error when entering MAC permission, error opening ports, are some examples.
- Security breaches - Security breaches and unauthorized traffic can knock down a network due to overloading. This overload can be caused by a virus that will quickly spread across all hosts.
- Obsolete Equipment - All obsolete and unsupported devices are a potential threat to network operation, not only performance but also security. It is preferable to dispose of obsolete equipment and buy a new one, rather than take risks.
- Human Error - Along with configuration errors, people make mistakes that can be as simple as turning off the wrong cable or not knowing the correct procedure. To avoid such errors, you must take actions such as proper team training, have adequate and up-to-date documentation and include labels on all devices.
- Incompatible changes - Changes to the network configuration made by, for example, "someone trying to unpack" and change an ip address out of range. The existence of records of the current devices and configurations is a way of avoiding the issue.
- Hardware failures - Any device can fail. Preventive maintenance, such as firmware upgrade, reduces risk. A more expensive way is to create redundancy to prevent a single point of failure from disrupting the entire network.
- Power failures - If the fault is of the electricity supplier, the reduction of the risk has an almost incom- patible cost (to install an emergency generator ...). But it can reduce some of the risk if you have a well-implemented backup policy. & Eacute; It is convenient to have extra power supplies for the equipment (commonly called "transformers"), because if a fault occurs, the replacement takes a few minutes and will not have a big impact on the work.
