Secure web programming plus end users' awareness are the last line of defense against attacks targeted at the corporate systems, particularly web applications, in the era of world-wide web.
Most web application attacks occur through Cross Site Scripting (XSS), and SQL Injection. On the other hand, most web application vulnerabilities arise from weak coding with failure to properly validate users' input, and failure to properly sanitize output while displaying the data to the visitors.
The literature also confirms the following web application weaknesses in 2010: 26% improper output handling, 22% improper input handling, and 15% insufficient authentication, and others.

Lab-5 Scanning and Enumeration Reconnaissance and inform.docxLaticiaGrissomzz
Lab-5: Scanning and Enumeration
Reconnaissance and information gathering methods were passive methods, meaning that they did not cause any alarm, alerts, and log file creation on the target systems: franklin.edu computers. In Lab-5, you will actively scan and enumerate target systems. These actions would cause some log files and probably trigger alerts if the target systems were used by a sensitive organization, such as a military or financial institution.
You will perform Lab-5 by using the Netlab environment provided by Franklin University. Netlab environment is an isolated environment with no Internet connection so that none of your actions will cause anything harmful for you or the target system. Section-1: Scan the Network Using nbtscan Tool
nbtscan is used for scanning networks to obtain NetBIOS names, file shares, and other information. It is one of the tools that come with Kali Linux. Nbtscan is a convenient tool to scan the active computers on the network quickly.
Windows machines have NetBIOS names by default. Linux/Unix computer may also have NetBIOS names if the Samba interoperability suite is installed.
Before starting scanning the network from Kali Linux, you have to learn the network address first.
1) Enter the Netlab environment
2) Open Kali Linux and enter the password (password: toor)
3) Open a terminal window
4) Type this command:
ifconfig
The IP address of your computer is 192.168.2.10, and the netmask is 255.255.255.0. That means the network address is 192.168.2.0/24. You will use this in your nbtscan.
5) Run a nbtscan by typing
nbtscan 192.168.2.0/24 to the terminal window. You will see all active computers along with IP addresses, NetBIOS names, and MAC addresses. That is an essential piece of information for a pentester and can be regarded as your initial attack surface.
Take a screenshot of the terminal window.
Section-2: Scan the Network by Using Nmap
You will perform another network scan by using a more versatile tool called Nmap. Nmap is one of the swiss knives of the pen-testers. It is a free and open-source tool and comes with Kali Linux. Nmap has many different scanning options; it can even perform vulnerability scanning in addition to network and host scanning. In this lab, you will first use Nmap's network/host scanning features, and then you will perform vulnerability scanning with Nmap.
1) Type in
nmap 192.168.2.0/24 -n -sn in the terminal window.
Take a screenshot of the terminal window.
Type in
mannmap in the terminal window to see the help page of the Nmap tool. Find why you used n and sn options.
Section-3: Perform a Port Scan Against a Host
In the previous section, you scanned the network by using Nmap. In this section, you will scan a specific host for open ports.
1) Type in
nmap 192.168.2.14 -n in the terminal window.
Take a screenshot.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks
