- What is the purpose of using MegaPing
MegaPing is the ultimate must-have toolkit that provides all essential utilities for Information System specialists, system administrators, IT solution providers, or individuals. MegaPing includes: Scanners: Comprehensive Security Scanner, Port scanner (TCP and UDP ports), IP scanner, NetBIOS scanner, Share Scanner. - What would be a reason to use the override feature in OpenVAS
You want to change a severity rating on a finding. - What is inverse TCP scanning
An inverse TCP scan results when a port is closed. The RFC standard states that if no response is seen from the target port, either the port is open or the server is down. This scanning method isn’t necessarily the most accurate, but it is stealthy; it sends garbage that usually won’t be picked up to each port. Cached - What is the difference between TCP scan and UDP scan
Transmission Control Protocol (TCP) is a nice orderly transaction protocol: TCP sends each packet in order, complete with error checking, verification, and a 3-way handshake to confirm each packet is successful. UDP doesn’t have any error checking but tends to be faster. - What is the primary purpose of polymorphic code for malware programs
Polymorphic viruses are complex file infectors that can create modified versions of itself to avoid detection yet retain the same basic routines after every infection. To vary their physical file makeup during each infection, polymorphic viruses encrypt their codes and use different encryption keys every time. - What would be the purpose of running a ping sweep
Ping sweep, also known as ICMP sweep or a ping scan, is a network scanning technique you can use to find out which IP addresses map to live hosts. In contrast to a single ping, a ping sweep uses ICMP (Internet Control Message Protocol) ECHO requests to communicate with multiple hosts at the same time. - What is the feature of OpenVAS
OpenVAS provides standard default scans, allows you to create customer scans, and enables users to create custom configs. “Out-of-the-box” OpenVAS provides some basic scan configurations – you can drill down by clicking on them to see additional details. - What are the 3 types of scanning in cybersecurity
Scanning could be basically of three types:- Port Scanning – Detecting open ports and running services on the target host.
- Network Scanning – Discovering IP addresses, operating systems, topology, etc.
- Vulnerability Scanning – Scanning to gather information about known vulnerabilities in a target.
- What would a TCP scanner tell you
TCP half-open port scanning (also known as SYN scanning) is a more commonly used technique for conducting port scanning. It’s a fast scan that can be used by hackers to detect open ports on the target computer. SYN packets ask for a response from the computer to which an ACK packet is received. - What are the three types of port scan
Types of Port Scanning:- Vanilla: The scanner tries to connect to all 65,535 ports.
- Strobe: A more focused scan, looking for known services to exploit.
- Fragmented Packets: The scanner sends packet fragments as a means to bypass packet filters in a firewall.
- User Datagram Protocol (UDP): The scanner looks for open UDP ports.

What is the purpose of UDP scan
UDP scans, like TCP scans, send a UDP packet to various ports on the target host and evaluate the response packets to determine the availability of the service on the host. As with TCP scans, receiving a response packet indicates that the port is open.
Why are polymorphic functions useful
Polymorphism in C++ allows us to reuse code by creating one function that's usable for multiple uses. We can also make operators polymorphic and use them to add not only numbers but also combine strings. This saves time and allows for a more streamlined program.
What is the main benefit of using polymorphic return types
The benefit of polymorphism is flexibility and extensibility. Instead of creating several different methods, we can declare just one method that receives the generic List type.
Why do we ping devices
Ping is used to troubleshoot connectivity. Most commonly, it's used to verify the connection between two machines. You might use ping to test a network printer or copier connection to determine whether a device is offline or to verify you can connect to a router.
What would be the purpose of running a ping sweep quizlet
– A ping sweep is used to determine which hosts are "up" or live on a network. Ping sweeps can be performed with tools such as Angry IP Scanner, nmap, and similar tools.
When would you use OpenVAS
A vulnerability scanner enables the monitoring of networks, systems, and applications for security vulnerabilities. Vulnerability management scanners like OpenVAS identify and classify potential points of weakness in your infrastructure, quantify the possible risk, and recommend mitigations to remediate the problem.
What is the difference between Nessus and OpenVAS
OpenVAS and Nessus are two of the leaders in the vulnerability scanning market. Nessus is best for companies that want more of an off-the-shelf vulnerability scanning solution, while the open-source OpenVAS is best for organizations that want more customization and integrations.
What are the 4 different types of scans
This includes X-rays, a CT scan, an MRI scan and ultrasound scans.
What are 4 examples of scanning devices
Such are as follows:Flatbed Scanners. The most popular type of optical scanner is a flatbed scanner, which scans documents on a flat surface.Sheetfed Scanners. A scanner that allows the only paper to be scanned, known as sheetfed scanners.Handheld Scanner.Drum Scanner.Photo Scanner.Film Scanner.Portable Scanners.
What details does TCP hide
Because Internet protocols define the unit of transmission and specify how to send it, TCP/IP can hide the details of network hardware, allowing many types of network technologies to connect and exchange information.
How to find someone’s port with their IP
The port number is “tacked on” to the end of the IP address, for example, “192.168. 1.67:80” shows both the IP address and port number. When data arrives at a device, the network software looks at the port number and sends it to the right program.
What does a port scan check for
A port scan is a common technique hackers use to discover open doors or weak points in a network. A port scan attack helps cyber criminals find open ports and figure out whether they are receiving or sending data. It can also reveal whether active security devices like firewalls are being used by an organization.
Which method of port scanning is the most popular
“Nmap,” which stands for Network Mapper, is the most widely used port scanning tool. A favorite of system administrators, it can be installed on Windows, Linux, MacOS or built from source code.
Why would anyone use UDP
UDP is commonly used for applications that are “lossy” (can handle some packet loss), such as streaming audio and video. It is also used for query-response applications, such as DNS queries.
What are examples and reasons for why you would use UDP for an application
UDP has a number of benefits for different types of applications, including: No retransmission delays – UDP is suitable for time-sensitive applications that can't afford retransmission delays for dropped packets. Examples include Voice over IP (VoIP), online games, and media streaming.
