As the cybersecurity world keeps changing, using AI and ML in threat detection and response will become more important for companies.

Deception Technology: Trapping and Misdirecting Adversaries

In the world of cybersecurity, threat hunters are always looking for new ways to outsmart hackers. Deception technology is a key tactic. It uses decoys and honeypots to trick hackers and uncover their plans.

Deception technology works well against hackers who target important assets or use sneaky methods. By setting up fake assets, companies can distract hackers. At the same time, they learn about the hackers' methods and weaknesses. This knowledge helps security teams catch and stop the threats.

Honeypots: Luring and Monitoring Attackers

Honeypots are at the core of deception technology. They are decoy systems that attract and engage hackers. Honeypots can be simple or complex, offering deep insights into how hackers work.

• Low-interaction honeypots mimic services to gather basic threat info. They are easy and fast to set up.
• High-interaction honeypots are more advanced. They keep hackers busy for longer, giving a detailed look at their tactics.
• Using different honeypots together gives a full view of threats. This helps security teams defend better against many attacks.

By watching honeypot traffic, companies learn about threats, their origins, and what interests hackers. This info helps improve security and fix weaknesses that were used.

Deception technology is a strong tool for cyber threat hunters. It lets them surprise and outsmart hackers. This way, security teams can keep up with the changing threat scene.

Hunting Across the Cyber Kill Chain

Effective cyber threat hunting needs a wide approach across the cyber kill chain. By actively searching for signs of trouble at each attack stage, teams can find hidden threats early. This helps stop attacks from getting worse.

Detecting Lateral Movement and Privilege Escalation

Spotting lateral movement and unauthorized privilege escalation is key. Attackers often sneak into the network and then move to other systems. They aim to get to sensitive data and systems.

By watching user actions, network traffic, and system logs, analysts can spot odd behavior. This might show a user account is compromised or someone is trying to get in without permission.

Identifying Data Staging and Exfiltration Attempts

Another important part of threat hunting is catching data staging and exfiltration tries. Attackers might collect sensitive info before trying to take it out of the network. By looking at network traffic, file access logs, and other data, teams can find suspicious actions. These could mean a data breach is coming.
