Importance of Threat Intelligence



Introduction:
In the cyber security world, threat intelligence become one of the most valuable weapon to fight the attackers, threat actors and part time hackers. Even at the heights of attackers like state sponsored attacks, threat intelligence able to detect and give good time to fight against them. Many usually asked us, what the use of collecting threat intelligence is. We answered them in this way, many attacks are sector based or targeting specific industry on the attackers’ interest. So we can collect those alert from difference sources and maintain the threat intelligence platform. Using that, we can detect attacks in the log monitoring and proceed to block them.

This is how it generally works. But if you go for deeper analysis on threat intelligence we will find more things like types of threat intelligence, how it is helpful in fighting against threat actors. Threat intelligence are categorised in to three types:

  • Strategic Intelligence
  • Operational Intelligence
  • Tactical Intelligence


Strategic Intelligence:

It’s a high-level one. People in the commanding position is required for thorough determination to critically assess threats.

Operational Intelligence:

It’s totally about how the organisation is working on determining the proactive assessment on the future cyber threats which is targeted on the organisation based on the sector based attacks.

Tactical Intelligence:

It’s all about attacker methodologies which is like tools, and tactics, and how dangerous the attacker is.

Conclusion:

Overall, threat intelligence will enhance the cybersecurity posture and holistic risk management policies. So the decision making after the detection of intrusion will be better and lessons learned will be more valuable.

Conclusion

It is important to remove the adware plugins and check the default homepage in web browser. If we didn't know about the plugins, extensions installed and unknown homepage in our web browser then it is high chances that the system is infected with hijacker infection of this kinds. Highly recommended to update the anti-malware software with latest update, also use additional adware cleaner from top AV programs. Bringing back the web browser to default settings can fight the browser hijack. Also recommended to block the listed cnc addresses in the firewall to prevent this attacks.
