 PAC files are scripts that tell web browsers how to use proxies on the network. They use if-else statements to determine whether to use a proxy or a direct connection for traffic between the PC and the host, based on criteria such as the destination URL, the source IP address, or the network subnet12. The WSA can host PAC files on port 9001 by default, and this port can be changed in the PAC file hosting settings2. If the WSA host port is changed, the default port does not redirect web traffic to the correct port automatically; the browser needs to point to the new port in the PAC file URL2. The WSA does not host PAC files on port 6001 by default2. PAC files do not direct traffic through a proxy when the PC and the host are on the same subnet by default; this behavior depends on the PAC file logic12. References:

Cisco Umbrella Investigate is a cloud-based service that provides interactive threat intelligence on domains, IPs, and files. It helps security analysts to uncover the attacker’s infrastructure and predict future threats by analyzing the relationships and evolution of internet domains, IPs, and files. It also integrates with other Cisco security solutions, such as Cisco Secure Network Analytics, Cisco Secure Cloud Analytics, and Cisco pxGrid, to provide a holistic view of the network and cloud security posture. Cisco Umbrella Investigate is based on the data collected by Cisco Umbrella, which processes more than 620 billion DNS requests per day from over 190 countries. Cisco Umbrella Investigate uses statistical and machine learning models to automatically score and classify the data, and provides a risk score for each domain, IP, and file, along with the contributing factors and historical context. Cisco Umbrella Investigate also allows security analysts to query the data using a web-based console or an API, and to visualize the results using graphs, tables, and maps. Cisco Umbrella Investigate is the most complete and interactive threat intelligence solution that helps to prevent cyber attacks before they happen. References :=

In XSS, an attacker will try to inject his malicious code (usually malicious links) into a database. When other users follow his links, their web browsers are redirected to websites where attackers can steal data from them. In a SQL Injection, an attacker will try to inject SQL code (via his browser) into forms, cookies, or HTTP headers that do not use data sanitizing or validation methods of GET/POST parameters.
