Threat Hunting Requirements

1. Use algorithms and tools to actively hunt of attacks in large volume

of data and create alerts that are passed on to analysts.

2. Define, develop, implement, update and maintain Hunting

Framework which contains: Create Strategic Hunt Missions which

are objective based to identify malicious activity that has not

triggered an alert. Search for Indicators of Compromise received

from Threat Intelligence and Analytics

3. Create knowledge base of IOCs

4. The service should able to detect threats from various attacks

vectors such as malware, web application attacks, network attacks,

watering hole attacks, DNS attacks, insider threat, and data

exfiltration but not limited to. List the detection use cases which can

detect above attacks using pre-built machine learning techniques

and analytical models.

5. Analytics using machine learning techniques should use multiple

sources to identify malicious activity. A minimum the following

sources should be used but not limited to:

IPS/IDS, Proxy, FW, WAF, Anti APT, EDR, AV, Internet/Mail gateway,

Windows & Linux logs, DNS.

6. Bidder should have analytical models to detect different stages of

Cyber Kill chain.

7. Network Threat Hunting should leverage existing network sources

for better detection of advanced attacks. Network sources should

include Net flow, Proxy, DNS, IPS, VPN, Firewall, WAF,

AD/Windows, Email logs etc.

8. Network threat hunting should use AI on network sources and

enable hunting for attacks including but not limited to Lateral

Movement, Malware Beaconing, Data Exfiltration, Watering Hole,

Targeted network attacks, Dynamic DNS attacks

9. The service must be capable of identifying suspicious or hitherto

undiscovered communication patterns to uncover hidden,

advanced threats missed by automated, preventative and detective
