How do engineers make cyber networks safer?

Engineers that work within the IT and Cyber field such as network engineers help make networks safer by taking responsibility for the overall design and management of the network and security systems, as well as ensuring the the network is secure from cyberthreats such as malware and other bugs. Some important tools to help keep a cyber network safe are Intrusion Detection Systems (IDS) and Firewalls. Intrusion Detection Systems help monitor network traffic and detect malicious activity or other network violations. A firewall uses methods such as packet filtering, network address translation, proxy services, and Virus Scanning, and content filtering to help function. The main purpose of a firewall is to check and monitor incoming and outgoing traffic to help with overall network protection. With all of the protections provided by Firewalls, they do have limitations such as attacks through email, and other restrictions and usability. A virtual private network is also an option to help keep a network secure, and it also included with firewall products. When using a VPN, as long as the encrypted tunnel connected to the networks remains secure, the VPN is also secure. When discussing specific engineering systems such as SCADA, these tend to have fewer firewall options by design, and many networks that deal with engineering control systems are ignored, which can be catastrophic if hacked, resulting in damages, injuries, and death. These issues draw attention toward the need for more to be done regarding engineering control systems, which are already estimated to be five to ten years behind regular IT systems. In conclusion, while network engineers are certainly crucial to ensure overall network safety, it’s also equally important that the users of the network maintain high levels of cyber hygiene to ensure that the network remains secure.
