Script scanning and how it works. The script scanner operates as a proxy component to the real Windows scripting host component. It intercepts scripts, then scans them before they are executed. For example, the script scanner confirms: If the script contains a potential threat, the script is not executed.
How do I run a script scan?
Script scanning is normally done in combination with a port scan, because scripts may be run or not run depending on the port states found by the scan. With the -sn option it is possible to run a script scan without a port scan, only host discovery.
Why does my script scan take so long to load?
VSE scans scripts when processes (usually Iexplore or Firefox) send them to the scripting host engine. The load delay occurs because of the way Internet Explorer is designed. For example, Internet Explorer sends the scripts to the scripting host when a page is loaded. But, Firefox sends the scripts only when they have to be run.
What are the command-line arguments specific to script scanning?
These are the five command-line arguments specific to script scanning: Performs a script scan using the default set of scripts. It is equivalent to --script=default. Some of the scripts in this default category are considered intrusive and should not be run against a target network without permission.
Is it possible to disable the scriptscan feature?
Although it is possible to disable ScriptScan, McAfee recommends that you first create and test exclusions before you completely disable this feature. There is some security risk in disabling ScriptScan. The reason is because applications like Outlook and Internet Explorer can render and execute scripts before a file has been created.

Nmap Script and Version Scan
Nmap provides script scanning which gives nmap very flexible behavior to get more information and test about the target host. This feature is called Nmap Scripting Engine (NSE). NSE gives user the ability to write scripts for test. Lua is programming language supported by NSE. NSE have some vulnerability detection scripts too.
Enable Script Scan
To use different category scripts in the nmap script NSE should be enable for script scan with -sC . This will by default enable default category scripts for the target
List Of Available NSE Scripts
Now we want to use specific script for our scan but first we should list and get information about these script Nmap have a web page where all scripts are listed.
Run Specific Script
By default default category scripts are fired while nmap scan but if we want to run specific script we can specify the script name or category name like below.
Run Specific Category Script
We can specify the whole scripts in a category the same as script by providing category name. Be aware that my system is a test system so I specify dangerous categories. In this example we run intrusive category scripts.
Exclude Script Category
While specifying script category we can specify a category to exclude like below.
Provide Script Arguments
Some scripts need arguments to work. Arguments can be provided like below.
Environment
For supported environments, see KB51111 - Supported platforms for VirusScan Enterprise .
Problem
Webpages load slowly when you enable the VSE 8.x ScriptScan feature. No significant improvement in performance is seen after you add a specific URL to the allow list. After you enable debug logging for ScriptScan, the index file includes records similar to the following: NOTE: Debug logging instructions are provided by Technical Support.
Cause
VSE scans scripts when processes (usually Iexplore or Firefox) send them to the scripting host engine. The load delay occurs because of the way Internet Explorer is designed.

Scanning
After data sources are registered in your Azure Purview account, the next step is to scan the data sources. The scanning process establishes a connection to the data source and captures technical metadata like names, file size, columns, and so on.
Ingestion
The technical metadata or classifications identified by the scanning process are then sent to Ingestion. The ingestion process is responsible for populating the data map and is managed by Azure Purview.
Next steps

Task 2 - Introduction
The more knowledge you have about a target system, the more options you have available. This makes is imperative that proper enumeration and information gathering is carried out before exploitation.
Questions
Q1: What networking constructs are used to direct traffic to the right application on a server?
Task 3 - Nmap Switches
There are versions of Nmap available for both Windows and Linux; however, most people will use the Linux version and you should too.
Task 4 - Scan Types (Overview)
When port scanning with Nmap, there are three basic scan types. These are:
Task 5 - TCP Connect Scans
To understand TCP Connect scans ( -sT) it is important that you understand the TCP 3-way handshake (this is discussed in the Introductory Networking room)
Task 6 - SYN Scans
SYN Scans ( -sS) are used to scan the TCP port-range of a target or targets; however, the two scan types work slightly differently. SYN scans are sometimes referred to as " Half-open " or " Stealth "
Task 7 - UDP Scans
Rather than initiating a connection with a handshake, UDP connections rely on sending packets to a target port and hoping they make it which makes UDP significantly more difficult to scan.
What Is Body Scan Meditation in Mindfulness?
The term “body scan” originated with the mindfulness-based stress reduction (MBSR) program introduced by John Kabat-Zinn in the 1970s (Anālayo, 2020).
3 Benefits According to Research
Although MBSR has been studied extensively as a program and shown to have multiple benefits for both physical and mental health, body scan meditation has been studied less as it is only a tool used within the MBSR program.
How to Do Body Scan Meditation
The traditional body scan meditation as taught in MBSR lasts about 30–45 minutes. In this practice, the meditator is lying down. Kabat-Zinn purposely decided to have the practitioner lie down because many of his first patients were in too much pain to complete a 30-minute seated meditation (Anālayo, 2020).
3 Scripts for Guided Body Scan Meditation
Here is a brief and helpful body scan script from Kabat-Zinn’s (2009, p. 155) bestseller Wherever You Go, There You Are: Mindfulness Meditation in Everyday Life:
