Engineers play a major role in making cyber networks safer by using various techniques to reduce security risks and vulnerabilities. Here are some ways engineers make cyber networks safer:

  1. Encryption: Encryption converts data into a coded language to prevent unauthorized access. Engineers use encryption algorithms to secure sensitive data such as passwords, personal identification numbers (PINs), and credit card information. Encryption helps to prevent hackers from accessing confidential information even if they manage to gain access to the network.
  2. Firewalls: Firewalls are a barrier between a trusted internal network and an untrusted external network. Engineers install firewalls at the perimeter of a network to prevent unauthorized access to the network. Firewalls are typically configured to block all incoming traffic except for authorized traffic that is explicitly allowed.
  3. Intrusion Detection Systems (IDS): An IDS software application monitors network traffic for signs of unauthorized access or malicious activity. Engineers use IDS to detect port scanning, denial-of-service (DoS) attacks, and virus/malware infections. IDS alerts network administrators when an attack is detected, allowing them to take immediate action to mitigate the threat.
  4. Access Control: Engineers implement access control policies to limit access to sensitive data and resources. Access control policies ensure that only authorized personnel have access to sensitive data such as financial records or confidential company information. Engineers use authentication mechanisms such as biometrics, passwords, and smart cards to ensure that only authorized personnel can access sensitive data.
  5. Vulnerability Scanning: Engineers perform vulnerability scans to identify weaknesses in a network. Vulnerability scanning tools check network devices and software for known security vulnerabilities. Once vulnerabilities are identified, engineers can take steps to patch or mitigate them before attackers exploit them.

In conclusion, engineers play a critical role in making cyber networks safer. They use encryption, firewalls, intrusion detection systems, access control policies, and vulnerability scanning techniques to secure networks and protect against cyber threats. As new threats and vulnerabilities emerge, engineers continue to develop and implement new security measures to keep networks secure.
