Questions and Answers

What is a key factor in IPS sensor deployment?

Network topology (correct)
Type of detected intrusion activity
Type of signature used
IPS sensor brand

What triggers an alarm in an Atomic signature?

A single packet or activity that matches a configured signature (correct)

A sequence of operations across multiple hosts
A detection of a composite signature

What is the main difference between Atomic and Composite signatures?

The number of hosts involved (correct)
The duration of time to detect the signature
The type of packet examined

Match the following ASA Firewall features with their descriptions:

ASA Virtualization = Each context is an independent device, with its own security policy, interfaces, and administrators. High Availability = Both platforms must be identical in software, licensing, memory, and interfaces, including the Security Services Module (SSM). Identity Firewall = control and security policy mechanisms by allowing users, or groups, to be specified in place of source IP addresses. ASA Threat Control = protection against tens of thousands of known exploits. Signup and view all the answers

Match the following ASA Firewall features with their functions:

Study Notes

Factors Affecting IPS Sensor Selection and Deployment

Network traffic amount is a key factor in IPS sensor selection and deployment
Network topology is a crucial factor in IPS sensor selection and deployment
Security budget is a significant factor in IPS sensor selection and deployment
Availability of security staff to manage IPS affects sensor selection and deployment

Signature Categories in IDS and IPS

Atomic signatures: simplest type, consists of a single packet, activity, or event that matches a configured signature, triggering an alarm and signature action
Composite signatures: identify a sequence of operations distributed across multiple hosts over an arbitrary period of time
