Engineers know that in order to make cyber networks safer, they must make sure the systems they build are trustworthy and meet the correct security requirements. This means making sure that all of the base architecture of the cyber network is designed carefully with these strict security principles in mind. Businesses often have assets which need to be protected, which is why engineers must work to make cyber networks safer. When talking about a cyber network, it can refer to both the internal network which connects the local workstations and other devices together, as well as the external network which is the internet where customers connect from and attacks happen. The primary infrastructure needed to protect a network is a firewall. Firewalls come in various types such as hardware based firewall devices and software based firewalls that can be used on each workstation or a server that all workstations are connected to. Firewalls are primarily concerned with blocking connections to specific ports and blocking out traffic based on rules that either state these IP addresses are allowed or these IP addresses are not allowed to make connections. This is done through whitelisting\/blacklisting. Another widely used technology is Virtual Private Networks. When having remote employees, they may connect from unsafe public wifi networks. These networks can be sniffed allowing anyone on the same network to view all of the network traffic. VPNs combat this by encrypting this traffic in a \u201ctunnel\u201d which allows the employee to keep business data safe. These also can be implemented locally to bolster security as well. Although these technologies limit many attack vectors, systems like Intrusion Detection Systems are still needed. Hackers are always improving and some will find a way past the firewall which is why you need a device that can notify you when this happens. Intrusion prevention systems can also work along firewalls for extra security.<\/p>\n","protected":false},"excerpt":{"rendered":"
