Cyber
security is an important part of computer systems, but its importance has
increased significantly in recent years. This program covers areas where cyber
security is a key issue, but with different security elements that can be
exposed to different threats and attacks. It also covers the methods and
techniques used to secure computer systems and data to meet and protect these
requirements.
Areas
of focus include computer operating systems (and increasingly, distributed
operating systems), distributed applications (such as e-commerce and the
Internet), embedded systems (from smart cards to large industrial and
communications systems) and job. The systems and processes reviewed include
cryptography, authentication and authorization, and access control.
In
addition, the program combines legal, ethical and professional concepts, for
example, to address concerns about data protection, privacy and the social
impact of IT systems.
Cybercrime,
also known as computer crime, is the use of computers for illegal purposes,
such as fraud, child pornography and intelligence trafficking, identity theft
or breach of privacy. Cybercrime, especially through the Internet, has grown
significantly as computers have become central to business, entertainment and
government.
Due
to the early and widespread use of computers and the Internet in the United
States, most of the early victims of cybercrime are Americans. However, in the
21st century, there is almost no village of one type or another crime that is
not affected by the Internet.
In
this article, you will learn about cybercrime: definitions, examples, types and
prevention.
What is Cybercrime?
Cybercrime
is a criminal activity that targets or uses computers, computer networks or
network devices. Most cyber-crimes are committed by cyber criminals or hackers
who want to make money. However, cybercrime sometimes seeks to destroy
computers or networks for reasons other than profit.
These
can be political or personal. Cybercrime can be perform person or group peoples.
Some cyber criminals are organized, use advanced techniques, and are highly
skilled. Others are novice hackers.
Cybercrime is any crime committed online or initiated online. Cyber criminals often commit crimes by securing computer networks or devices.
Cybercrime can range
from security breaches to other cyber crimes include things like "revenge
pornography", cyber bullying, stalking, and child abuse. Terrorists collaborate
on the Internet, transmitting terrorist activities and crimes in cyberspace.
Definition of Cyber Crime
New
technology creates new crime opportunities but few new types of crime. What is
the difference between cybercrime and traditional crime? Obviously, one
difference is the use of digital computers, but technology alone is not enough
to account for any differences that may exist between different areas of crime.
Criminals don't need computers to commit fraud, transmit child pornography and
intellectual property, steal identities, or violate people's privacy.
All
of these activities existed before the prefix "cyber" became
ubiquitous. Cybercrime, especially related to the Internet, represents an
extension of criminal behavior in the area of certain illegal activities.
Most cyber crimes are attacks against information about individuals, companies or
governments. Although these attacks do not take place physically, they take
place on the personal or corporate body, which is the identity of information
that identifies people and companies on the Internet.
In
other words, in the digital age, our virtual identity is an important part of
everyday life: we are a collection of numbers and identities in many computer
databases owned by governments and companies.
Cybercrime
defines the core between networked computers and our lives, and the
vulnerability of the truth is as strong as individual identity.
The
United States Department of Justice (DOJ) divides cybercrime into three
categories:
1.
The crime of the computing device is the purpose for example, to access the
network.
2.
Crimes in which computers are used as weapons -for example, launching a denial
of service (DoS) attack.
3.
The crime of using a computer as a criminal tool - for example, using a
computer to store data obtained illegally.
The
Council of Europe Convention on Cybercrime, to which the United States is a
signatory, defines cybercrime as a range of crimes, including unauthorized
access to data, system interference that compromises the integrity and
availability network and copyright infringement.
The
need for Internet connectivity has led to an increase in the volume and speed
of cybercrime activity, because the criminal no longer needs to be physically
present when committing a crime.
The
speed, convenience, anonymity, and limitlessness of the Internet make it easy
to commit various types of computer crimes, such as ransomware, fraud, and
money laundering, as well as crimes such as extortion and bullying.
Individuals
or groups with limited technical skills, or highly organized global criminal
groups may include skilled developers and others with relevant skills. To
reduce the chances of detection and prosecution, cybercriminals often choose to
work in countries with weak or non-existent cybercrime laws.
Types of Cyber Crime
Here
are 5 of the cybercrimes that will most affect businesses and individuals:
1.
Fraud
2.
Spoofing websites
3.
Ransomware
4.
Malware

Follow
along below to understand what hackers use to steal data, their tools, and how
to protect yourself. In the end, the goal is to be comfortable rather than
sorry, even if that means taking a minute or two to get another safety measure.
PHISHING SCAM
The
majority of successful cyber-attacks - 91% according to PhishMe research -
begin when curiosity, fear or a sense of urgency prompts someone to enter
personal data or click on a link. Phishing communications mimic messages from
someone you know or a company you trust. They are designed to trick people into
giving personal information or clicking on malicious links that download
malware. Many of phishing bouts are hurled every day.
What you can do:
Stop trusting your email. They are not always what they seem. Making Security consciousness
and phishing drill can assistance your squad defends against phishing attacks.
Training can show the telltale signs and learn to recognize targeted phishing
campaigns, as well as malicious links, and encourage users to avoid links and
attachments. The easiest way is to enter the website by clicking the correct
URL in their browser.
SPOOFING WEBSITES
The
word spoof means trick, trick or trick. Website phishing occurs when a website
is made to look like something that tricks you into thinking it's a legitimate
site. This is done to gain your trust, gain access to your system, steal data,
steal money or spread malware.
Website
spoofing works by impersonating a legitimate website with a large company logo,
logo, user interface and even domain name to trick users into entering their
username and password. This is how bad guys get hold of your data or install
malware on your computer. Websites are often used with email links that link to
illegal websites. It is identity theft and phishing cost businesses $354
million.
What you can do:
The easiest thing you can do is to ignore and delete anything you don't plan
on. The right companies will have many ways to contact you if they want to
reach you. Save time and frustration by applying common sense to a
"quick" analysis of the information. Also, pick up the phone or go
directly to the trust department to ask.
RANSOMWARE
Ransomware
is a modern, crime-fighting technology that has been around for years:
extortion. At its core, ransomware works when criminals steal something
valuable and demand payment in exchange for its return. For many companies,
this means hiding corporate data.
When
ransomware fails, business comes to a halt and employees can't do their jobs.
Without backup data to restore, transactions are often at the mercy of an
attacker who will hold your data in exchange for a decryption key that you can
buy with Bitcoin.
Ransomware
has grown into its own class of malware and should be a top concern for all
organizations. Ransomware damage has increased by 13%, over the past five years
combined, according to a new study.
What you can do:
Back up your data and start over, in a different location. Repetition and
redundancy are key to your success. If you only back up your system once a
week, or if your backups are delivered, you're going to have a big problem.
MALWARE
Norton
defines malware as "malicious software" designed specifically to
access or damage a computer. In the case of ransomware, it is designed to
capture your data, but it is not the only type. The goals of malware can be
many - power, influence, money, information - but the result is always the same
- recovery efforts are long and often expensive.
Common types of malware include:
•
Viruses spread, corrupt performance and corrupt files
•
Trojans masquerade as legitimate software that create small backdoors to allow
other malware to enter your network
•
Worms can infect all devices connected to the network
•
Ransomware captures your data
•
botnets - networks of virus devices working together under the control of an
attacker
What
you can do: Be careful about e-mail attachments, avoid suspicious websites
(check the spelling carefully), install and update a high-quality anti-virus
program regularly.
IOT HACKING
The
Internet of Things is a brave new world that has opened up knowledge about our
daily routines and web-based business processes. Whether we like it or not, all
these things connected to the Internet are collecting and exchanging data. As
you know, data is valuable and because of this, hackers will want to use any
device to collect it.
The
more we connect the "thing", the more the reward becomes for the
hackers. That's why it's important to remember that all personal and work
passwords are personal... and memories that we know will fail us from time to
time.
What you can do:
Use strong passwords generator to create unique passwords. Remember that when
working in business, everyone must take personal responsibility for ensuring
your online safety. You need to prioritize your risks and think about the
scenarios that may affect you, based on what you know about your unique
resources and team. Don't wait until it's too late to take quick action. Stay
focused on the future and work to improve your team to create a strong defense
against cyber-attacks.
A common example of cyber crime
Some
of the most common cybercrime attacks include distributed denial-of-service
(DDoS) attacks, which are often used to bring down systems and networks. This
type of attack uses the network's communication system against it by overriding
its ability to respond to connection requests.
DDoS
attacks are sometimes carried out purely for malicious purposes or as part of a cyber extortion scheme, but they can also be used to distract target groups from
other concurrent attacks or exploits. Infecting systems and networks with
malware is an example of an attack that is used to damage systems or harm
users.
It can be done by damaging the system, software or data stored in the system. Ransomware attacks are similar, but the malware works by encrypting or shutting down victim systems until a ransom is paid. Phishing campaigns are used to infiltrate corporate networks.
This can be done by sending fraudulent emails to
the group's users, tricking them into downloading attachments or clicking on
links that spread viruses or malware on their systems and through their systems
and business networks.
A
credential attack occurs when a cybercriminal attempts to steal or guess the
user ID and password of the victim's system or personal account. They can be
done using brute force attacks by installing keylogger software or by using
vulnerabilities in software or hardware that can expose the user's credentials.
Cyber
criminals may also attempt to hijack websites to edit or delete content or to
access or modify databases without permission.
For example, an attacker can use a structured query language (SQL) exploit to inject malicious code into a website, which can be used to exploit vulnerabilities in the website's database, allowing the attacker to access and destroy records or gain unauthorized access.
Subtle information and statistics,
such as client passwords, credit card numbers, personally identifiable
information, trade secrets and intellectual property. Other common examples of
cybercrime include illegal gambling, the sale of illegal goods, such as
weapons, drugs or counterfeit goods ¬ and the solicitation, production,
possession or distribution child pornography.
How to Protect Against Cyber Crime
Everyone who uses the Internet should be very careful.
Here are 11 tips you can use to
protect yourself from many online crimes.
1. Use Adequate Internet Security
It
is worth considering reliable security software such as Norton 360 and Life
Lock Select, which provide all-in-one protection for your device, privacy and
online identity, and help protect your private and financial information when
you entered.
2. Use strong Passwords
Do
not reuse your password on different sites and change it regularly. Make them
more complicated. That is to say you can use combination of at least 10
letters, numbers and symbols. Password management tools can help you keep track
of your passwords.
3. Keep your Software Up to
Date
This
is especially important with your operating system and Internet security
software. Cybercriminals often use vulnerabilities or vulnerabilities in your
software to gain access to your system. Addressing these exploits and mistakes
can reduce the risk of being a target of cybercrime.
4. Manage your Social Media
settiNgs
Keep
information about you private. Social criminals can access your personal
information using only a few data points, the more you share publicly, the
better. For example, if you post your pet's name or reveal your mother's maiden
name, you can reveal the answers to two frequently asked security questions.
5. Power up your Home Network
It's
best to start with a strong password and virtual private network. A VPN will encrypt
all traffic leaving your device until it reaches its destination. If
cybercriminals manage to hack into your communication lines, they will only
intercept encrypted data. It's a good idea to use a VPN whenever you use public
Wi-Fi, whether it's in a library, coffee shop, restaurant, or airport.
6. Give Adequate
Information and Advice to your Wards about the Internet
You
can teach your children about acceptable Internet use without cutting off the
news channel. Be sure that they understand when they come to you if they are existence
harassed, harassed or bullied online.
7. Link to Major Security
Vulnerabilities
If
you're dealing with a customer or have an account on a website that was
compromised by a security breach, find out what information the hackers got and
change your password immediately.
8. Take Steps to Protect
Yourself from Identity Theft
Identity
theft occurs when someone wrongfully obtains your personal data in a way that
involves deception or fraud, usually for profit. What? You may be tricked into
providing personal information over the Internet, for example, or a thief may
steal your information to gain access to your account information. This is why
it is important to protect your personal data. A VPN – short for virtual
private network – can also help protect the data you send and receive online,
especially when accessing the internet via public Wi-Fi.
9. Beware that Identity
Theft can Happen Anywhere
It's
good to know how to protect your identity even when you travel. There are many
things you can do to prevent criminals from getting your private information on
the road. These include keeping your travel plans on social media and using a
VPN when accessing the internet through your hotel's Wi-Fi network.
10. Look after the Children
Just
as you want to talk to your children about the Internet, you also want to
protect them from identity theft. Individuality steals often target kids
because their social safety number and credit past represent a clean slate. You
can help protect yourself from identity theft by being careful when sharing
your child's personal information. It's also good to know what to look for that
could mean your child's identity has been compromised.
11. Know what to do if you
are a Victim
If
you believe you have been the victim of a cybercrime, you should notify local
law enforcement and, in some cases, the FBI and the Federal Trade Commission. Your
report may assist the authorities in their investigation or may help prevent
criminals from exploiting others in the future. If you think your identity has
been stolen by cyber criminals. They are most guides you should be awake.
•
Contact companies and banks that you know have been scammed.
•
Keep a fraud alert and get your credit report.
•
Report identity theft to the FTC.
