Network Security

Having a secure network involves multiple layers of protection. Even if a cyberattack penetrates through one layer the other layers keep the systems secure.One of the most important (and most vulnerable) layers of protection involves people. People with access to protected systems should take great care to not inadvertently let in intruders. Fortunately, technologies such as 2-step (or multi-step) verification can stop intruders that have tricked authorized users into divulging important information.

Further, it is important that there are processes in place that detail how an organization (or individual) should deal with a cyberattack. If there are processes in place that detect cyberattacks, then it allows the victim more time to deal with the damage before it becomes irreperable. Once detected, steps can be made to investigate the attack and determine the next course of action. Hopefully, if caught soon enough, then steps can be made towards recovery.

There are a great deal of technologies that systems can utilize to keep out unauthorized users.

Encryption Encryption involves changing data to an unreadable format. This is done by using a key to encrypt the data. The key is then used to decrypt the data so it is readable again.
Firewalls Firewalls allow or block data packets from entering a system based on rules. These rules can be based on the source, destination, or protocol of the incoming data packets.
Intrusion Detection and Prevention System (IDPS) An IDPS is a software that monitors network traffic for any suspicious activity. The software can also stop cyberattacks before they get a chance to infiltrate. Often, this activity is logged and triggers an alert to the appropriate personnel so they can take additional actions.

It is important to remember that these technologies can be bypassed if a person is tricked into granting access to malicious actors. Here are the top 10 tips to keep your data safe and secure.
