HISTORY OF CYBER CRIME
In 1920 a "worm program" written by a college student shut down about 10 percent of computers connected to the Internet. This was the beginning of the era of cyber attacks.

HACKING
Hacking in simple terms means an illegal intrusion into a computer system and/or network .Also called as cracking!
Hacking means finding out weaknesses in an established system and exploiting them. A computer hacker is a person who finds out weaknesses in the computer and exploits it.

WHY DO HACKERS ATTACK?
For profit, protest, or challenge. A large fraction of hacker attacks have
been pranks Financial Gain Revenge Venting anger at a company or
organization Terrorism

DENIAL OF SERVICE ATTACK
Attack through which a person can render a system unusable or significantly slow down the system for legitimate users by overloading the system so that no one else can use it.
Act by the criminal, who floods the bandwidth of the victims network.

WHAT IS CYBER SECURITY?
Cyber security is a branch of computer security specifically related to the Internet.
It's objective is to establish rules and measure to use against attacks over the Internet.
![Page 22: Cyber crime & security](https://reader033.vdocument.in/reader033/viewer/2022052822/554bb84ab4c9053a298b4acc/html5/thumbnails/22.jpg)
ADVANTAGES OF CYBER SECURITY
Defend us from critical attacks.
Browse the safe website.
Internet security process all the incoming and outgoing data on our computer.

TOP SEVEN CYBER-SAFETY ACTIONS
1.Install OS/Software Updates
2.Run Anti-virus Software
3. Prevent Identity Theft
5. Avoid Spyware/Adware
7. Back up Important Files
6. Turn on Personal Firewalls
4. Protect Passwords
![Page 24: Cyber crime & security](https://reader033.vdocument.in/reader033/viewer/2022052822/554bb84ab4c9053a298b4acc/html5/thumbnails/24.jpg)
INSTALL OS/SOFTWARE UPDATES
24
Updates-sometimes called patches-fix problems with your operating system (OS) (e.g., Windows XP, Windows Vista, Mac OS X) and software programs (e.g., Microsoft Office applications).
Most new operating systems are set to download updates by default.
Be sure to restart your computer after updates are installed so that the patches can be applied immediately.
![Page 25: Cyber crime & security](https://reader033.vdocument.in/reader033/viewer/2022052822/554bb84ab4c9053a298b4acc/html5/thumbnails/25.jpg)
RUN ANTI-VIRUS SOFTWARE
25
To avoid computer problems caused by viruses, install and run an anti-virus program like Norton,Quick Heal,etc.
Periodically, check to see if your anti-virus is up to date by opening your anti-virus program and checking the Last updated date.
Anti-virus software removes viruses, quarantines and repairs infected files, and can help prevent future viruses.
![Page 26: Cyber crime & security](https://reader033.vdocument.in/reader033/viewer/2022052822/554bb84ab4c9053a298b4acc/html5/thumbnails/26.jpg)
PREVENT IDENTITY THEFT
26
Don't give out financial account numbers, Social Security numbers, driver’s license numbers or other personal identity information unless you know exactly who's receiving it. Protect others people’s information as you would your own.
Never send personal or confidential information via email or instant messages as these can be easily intercepted.
Beware of phishing scams - a form of fraud that uses email messages that appear to be from a reputable business (often a financial institution) in an attempt to gain personal or account information. Legitimate businesses will not ask for personal information online.

PROTECT PASSWORDS
27
Do not share your passwords, and always make new passwords difficult to guess by avoiding dictionary words, and mixing letters, numbers and punctuation.
Do not use one of these common passwords or any variation of them: qwerty1, letmein,etc.
Change your passwords periodically.
When choosing a password: Mix upper and lower case letters Use a minimum of 8 characters Use mnemonics to help you remember a difficult password
Store passwords in a safe place. Consider using KeePass Password Safe , an encrypted USB drive to store passwords.
![Page 28: Cyber crime & security](https://reader033.vdocument.in/reader033/viewer/2022052822/554bb84ab4c9053a298b4acc/html5/thumbnails/28.jpg)
AVOID SPYWARE/ADWARE
28
Spyware and adware take up memory and can slow down your computer or cause other problems.
Use Spybot and Ad-Aware to remove spyware/adware from your computer
Watch for allusions to spyware and adware in user agreements before installing free software programs.
Be wary of invitations to download software from unknown internet sources.
![Page 29: Cyber crime & security](https://reader033.vdocument.in/reader033/viewer/2022052822/554bb84ab4c9053a298b4acc/html5/thumbnails/29.jpg)
TURN ON PERSONAL FIREWALLS
29
Firewalls act as protective barriers between computers and the internet.
Check your computer's security settings for a built-in personal firewall. If you have one, turn it on. Microsoft Vista and Mac OSX have built-in firewalls.
Once your firewall is turned on, test your firewall for open ports that could allow in viruses and hackers.
Hackers search the Internet by sending out pings (calls) to random computers and wait for responses. Firewalls prevent your computer from responding to these calls.

BACK UP IMPORTANT FILES
30
Reduce your risk of losing important files to a virus, computer crash, theft or disaster by creating back-up copies.
Keep your critical files in one place on your computer’s hard drive so you can easily create a back up copy.
Save copies of your important documents and files to a CD, online back up service, flash or USB drive, or a server.
Store your back-up media in a secure place away from your computer, in case of fire or theft.
![Page 31: Cyber crime & security](https://reader033.vdocument.in/reader033/viewer/2022052822/554bb84ab4c9053a298b4acc/html5/thumbnails/31.jpg)
Physically secure your computer by using security cables and locking doors and windows in the dorms and off-campus housing.
Avoid leaving your laptop unsupervised and in plain view in the library or coffee house, or in your car, dorm room or home.
Set up a user account and password to prevent unauthorized access to your computer files.

Be sure to work with your technical support coordinator before implementing new cyber-safety measures.
Report to your supervisor any cyber-safety policy violations, security flaws/weaknesses you discover or any suspicious activity by unauthorized individuals in your work area.
