Identifying network security threats involves regular monitoring for unusual activity, such as unexpected traffic patterns or unauthorized access attempts. Utilizing intrusion detection systems (IDS), firewalls, and antivirus software can help detect and prevent common threats like malware, phishing attacks, and denial-of-service (DoS) attacks. Additionally, implementing strong access controls, regular software updates, and employee training on security best practices can mitigate risks and enhance overall network security posture.

✔Network Monitoring: Use tools to detect unusual traffic and communication with malicious domains. ✔Endpoint Protection: Deploy antivirus, anti-malware, and EDR solutions on endpoints. ✔Email Security: Implement spam filters and scan emails for malicious attachments or links. ✔Web Filtering: Block access to malicious websites & phishing pages. ✔Patch Management: Regularly update software to fix vulnerabilities. ✔Network Segmentation: Isolate critical systems & data from potential threats. ✔User Education: Train users to recognize & avoid phishing attempts. ✔Behavioral Analysis: Use tools to identify abnormal activities indicating malware. ✔Threat Intelligence: Stay updated with the latest threat information for proactive defense.

identifying and mitigating common network security threats like phishing tactics involves a multi-layered approach. Implementing email authentication techniques like SPF, DKIM, and DMARC can help verify email sources. Conducting regular employee training on recognizing phishing attempts is crucial. Utilizing anti-phishing tools and spam filters can also help detect and block malicious emails. Additionally, establishing incident response procedures to quickly address any successful phishing attacks is essential for mitigating their impact.

Lack of awareness, distraction, and overconfidence are key reasons why staff succumb to phishing. Education must target all these vulnerabilities. Modern phishing often lacks traditional signs like spelling errors, so focus should be on enduring indicators like email domains and the presence of hyperlinks or QR codes. Implementing technical measures such as warning banners on external emails can increase vigilance. Encouraging staff to monotask when reading external emails can also reduce distractions and their susceptibility to phishing.

Simplest way: Monitor and collect logs like user login, file access or modification, network activity, port number, outbound connection, total bytes sent, IP address, and event ID with the help of various solutions. 

1. Identify: -Unusual login attempts (time, place, unsuccessful attempts) -Unauthorised file/system access and other suspicious user behaviour 2. Mitigate: -Multi-factor authentication (MFA) and strong passwords -Least privilege access control, which limits user access to what they absolutely require. -Check user rights and access on a regular basis.

Identifying and mitigating common network security threats requires a holistic approach. Organisations need to perform regular penetration testing to uncover vulnerabilities and assess risks, ongoing monitoring of network traffic, and threat hunting for early threat detection. Additionally, they should establish comprehensive incident response plans for effective responses to security breaches.
