6.) The speed of a body is the distance it travels per unit of time. That means that we can also find out how far an object moves in a certain amount of time if we know its speed: we use the equation “distance = time x speed” Shanice’s car is traveling 10 miles per hour slower than twice the speed of Brandon’s car. She covers 93 miles in 1 hour 30 minutes. How fast is Brandon driving?
7.) The electrical current, I (amps), passing through an electronic component varies directly with the applied voltage, V (volts), according to the relationship V=I⋅R where R is the resistance measured in Ohms (Ω).
a. A scientist is trying to deduce the resistance of an unknown component. He labels the resistance of the unknown component x Ω. The resistance of a circuit containing a number of these components is (5x+20) Ω. If a 120 volt potential difference across the circuit produces a current of 2.5 amps, calculate the resistance of the unknown component.

5. Hardening Operating Systems
11/12/2022
“Attack on Microsoft systems using the Internet ”
1. Following are the some of the Microsoft system attacks;
MItM Attack:
Because of the vulnerability, an off-site attacker is able to get
access to the compromised system. Within the Windows LSA
service is where the vulnerability may be found. (Kumar &
Surisetty, 2011) An adversary operating from a distant location
has the ability to trick a domain controller into providing
NTLM authentication to them by calling a method on the
LSARPC interface. As a consequence of this, an adversary may
gain credentials and compromise the vulnerable system via the
use of the NTLM Relay Attack.
DDos:
During a DDoS attack, users are unable to connect to the
targeted service. During a distributed denial of service attack,
all of an app's available resources are used up. Attackers flood a
site with fake users to slow it down or bring it down entirely.
(Gomez & Valdez, 2006) The frequency and severity of these
episodes are both rising. According to statistics compiled by
Azure Networking, DDoS assaults will raise by 25% in the first
half of 2021 compared to the last quarter of 2020. In 2021,
Azure prevented 359.713 assaults on its worldwide
infrastructure, up 43 percent from the previous year. (Wu &
Sun, 2010) Regardless of industry or location, businesses of any
size are vulnerable to DDoS attacks. Internet gambling sites,
online stores, and telecommunication companies are frequent
targets of cybercriminals.
2. Following are the main 5 concerns;
Initial Breach Targets: Nobody hacks IT. Built Active Directory
forests are clean and updated. New OSes and programs emerge
throughout time. As Active Directory's administrative
advantages are recognized, more information is provided, more
PCs or programs are connected, and domains are altered to suit
6. new Windows capabilities. Even when new infrastructure is
introduced, other elements may not be maintained as well,
systems and applications may be neglected, and organizations
may forget they still have legacy infrastructure. Older, bigger,
more complex ecosystems are more vulnerable.
Disabling Security Features: Many businesses don't utilize
Windows Firewall with Advanced Security (WFAS) because
they feel it's too complicated to set up. Starting with Windows
Server 2008, the Windows Firewall is automatically configured
to provide just the minimum permissions required for each role
or functionality to function. When WFAS is turned off (and no
other host-based firewall is used), Windows becomes more
vulnerable. Firewalls at the network's perimeter protect against
attacks from the Internet but not from drive-by downloads or
compromised intranet systems.
Gaps in antivirus & Antimalware Deployments: Most
workstations in a company will have antivirus and antimalware
software installed, activated, and up-to-date, according to an
analysis of antivirus and antimalware deployments. With a few
notable exceptions, such as seldom connected workstations and
staff devices, antivirus and antimalware software is often easily
deployed, configured, and updated across the board.
Incomplete patching: Microsoft publishes security updates
regularly on the second Tuesday of every month, however in
severe circumstances when vulnerability is believed to represent
an imminent hazard to client systems, an update may be
delivered outside of the monthly security update schedule.
Whether a company is small and uses Windows Update to
handle system and application patching or large and uses
management software like System Center Configuration
Manager (SCCM) to deploy patches according to detailed,
hierarchical plans, a large number of customers patch their
Windows infrastructures in a timely fashion.
Misconfiguration: Even in environments where systems are
often kept up to date and patched, we regularly discover
vulnerabilities or misconfigurations in the operating system,
7. applications, and Active Directory. Depending on the nature of
the configuration problem, the attack may just affect the local
workstation, but in many cases, an attacker may actively seek to
"manage" further systems and eventually get access to Active
Directory.
3. There are three essential parts to every network;
Routers
Switches
Firewalls
Switches:
A switch is required to connect many computers together. While
PCs are the most common device that switches link, they are not
the only device that switches may connect. After a device is
connected to a switch, its Media Access Control (MAC) address
is revealed and used for routing. The switch includes the MAC
address in outgoing packets so that other network nodes may
determine which device generated them.
Routers:
In order to connect local area networks to the wider web,
routers are required. Packets with an IP address are sent further
by this L3 device. A router is a device that allows for
communication across different networks. With the help of
Dynamic Host Configuration Protocol, a router may give out IP
addresses to computers and other devices that are linked to it.
After then, the information may enter and leave the network as
needed. In order to connect to the web, NAT is essential.
Firewalls:
When a firewall is set up, it may either allow or prevent
information from accessing a network. As an example, a
firewall may be set up to allow only traffic from a limited range
of IP addresses and ports that have been verified as secure.
(Archiveddocs , nd) On the other hand, a firewall may monitor
the IP address of the source of a packet that is being sent
several times per second. Maybe there was a distributed denial
of service attack that would be weird (DDoS)
