Introduction To Cyber Security
The hacker successfully accesses the files and transfers them to their
own computer. This scenario can lead to various legal ramifications,
such as loss of company secrets, leakage of information, or even
industrial espionage.So, what are we going to discuss in this video? Let's
start with the basics: What is cyber security? Why is cyber security
necessary in today's world? How does cyber security work? Who is a
cyber security expert? What are the required skills and certifications?
What is Cyber Security? Cyber security is a process, design, and
architecture created to protect networks and devices from attacks,
damage, or unauthorized access. Its main goal is to safeguard
businesses and individuals from cyber criminals. Advantages of Cyber
Security Protecting business: Implementing cyber security measures
helps protect businesses from hackers, resulting in increased
productivity and confidence. Increased confidence: Cyber security
measures inspire confidence in clients and customers, as they feel more
secure sharing their information with an organization. Stability: Cyber
security helps make applications and websites more stable by
protecting them from external threats. Protecting customers:
Organizations holding customer data need to ensure its security to
protect their customers from cyber attacks. The Three Pillars of Cyber
Security There are three main pillars of cyber security: confidentiality,
integrity, and availability (CIA). These pillars ensure that data remains
confidential, trustworthy, and available at all times. Confidentiality The
principle of confidentiality ensures that information and functions can
only be accessed by authorized parties. This includes password
protecting files and preventing unauthorized users from accessing data.
Integrity The principle of integrity ensures the trustworthiness of data,
ensuring that it is not modified by unauthorized users. This is crucial,
, especially for sensitive information. Availability The principle of
availability ensures that data is made available to authorized users
whenever and wherever they need it. This is essential for systems,
functions, and services to operate smoothly. Types of Cyber Crime
Cyber crime refers to any criminal activity or unauthorized action
involving the use of computing devices. It can include activities like
phishing attacks, stealing money from bank accounts, or compromising
personal information for identity theft. There are three main types of
cyber crime: Computer-assisted crime: Computers are used as tools to
assist in committing a crime, such as online fraud or bank hijacking.
Computer-targeted crime: The computer itself becomes the target of a
crime, such as denial of service attacks or spreading viruses. Computer-
incidental crime: The computer is used temporarily to store data related
to a crime, such as child pornography.
Common Attacks in Cyber Security
Common cyber attacks include:
Denial of Service (DoS) attack: Consuming resources to prevent
legitimate users from connecting to a server.
Malware attacks: Delivering malicious software to infect and render a
victim’s machine useless.
Man in the middle attack: Intercepting data packets by positioning
oneself between the victim’s machine and the router.
Phishing attack: Sending deceptive messages impersonating legitimate
organizations to trick users into revealing confidential information.
Drive-by attack: Compromising web applications and embedding scripts
or commands.
