Week 7 - TCP/IP and Network Security
This week, we reviewed TCP/IP and Intrusion Protection/Intrusion Prevention.
What is TCP/IP
TCP is like sending a package with tracking and a signature required. When you send data, TCP ensures it arrives, and if anything gets lost, it resends it. If frames arrive out of order, TCP reorders them.IP is the system that gives every device an address so data knows where to go.
TCP/IP is not very secure and relies on external sources, such as encryption and authentication, to help ensure security.
Intrusion Protection/Intrusion Prevention
Intrusion Protection/Intrusion Prevention is a multi-layered security approach that relies on firewalls, network security monitoring tools, antivirus software, web filtering, and VPNs, among others. This multi-layered approach allows a backup method to catch what another method may have missed. These layers must stay up to date as advancements are made to ensure top-tier network security.
Conclusion
In conclusion, TCP/IP, paired with Intrusion Protection/Intrusion Detection, ensures data is transferred safely and reliably.
You should learn more about these methods on your own to ensure your security is up to date.
