Engineers use firewalls to filter and monitor network traffic, allowing only authorized traffic to pass through and blocking potentially harmful traffic. Firewalls are essential components of network security and can be implemented at different levels, such as network perimeter, internal network, and individual systems. They also implement access controls to ensure that only authorized users have appropriate access to the network and its resources. This involves the use of strong authentication methods, such as multi-factor authentication, and proper user privilege management to limit access based on roles and responsibilities. Engineers conduct regular employee education and training programs to raise awareness about cybersecurity best practices, such as safe browsing, email hygiene, and social engineering awareness. This helps to ensure that employees are knowledgeable about potential security risks and follow proper security protocols. Engineers use threat intelligence sources to stay updated on the latest threats and vulnerabilities, enabling them to proactively take preventive measures to safeguard the network. Engineers deploy security monitoring tools to continuously monitor network traffic and system logs for suspicious activities. In the event of a security incident, engineers follow an incident response plan to quickly detect, contain, and remediate security breaches to minimize the impact and prevent further damage.

Regular Security Audits and Testing: Engineers conduct regular security audits and penetration testing to identify vulnerabilities in the network and validate the effectiveness of security measures. This helps to identify and address potential weaknesses before they can be exploited by attackers.
