Cyber security is the body of technologies, processes and practices designed to protect networks, computers programs and data from attack, damage or unauthorized access.
ORCyber Security is the protection of information systems from theft or damage to the hardware, the software, and to the information on them.
NEED FOR CYBER SECURITY
Cyber security is necessary since it helps in securing data from
threats such as data theft or misuse, also safeguards your
system from viruses.
Vulnerabilities and AttacksA vulnerability is a system susceptibility or flaw. To secure a computer system, it is important to understand the attacks that can be made against it, and these threats can typically be classified into one of the categories below:
Backdoors: It is a cryptosystem or an algorithm, is any secret method of bypassing normal authentication or security controls. Denial-of-Service Attack: It is designed to make a machine or network resource unavailable to its intended users.Eavesdropping: It is the act of surreptitiously listening to a private conversation, typically between hosts on a network.Spoofing: It is a fraudulent or malicious practice in which communication is sent from an unknown source disguised as a source known to the receiver.Phishing: It is the attempt to acquire sensitive information such as usernames, passwords and credit card details directly from users.

Systems under Risk
Serious Financial damage has been caused by security breaches, The 2003 loss estimates by these firms range from $13 billion(worms and viruses only) to $226 billion(For all forms of covert attacks). The reliability of these estimates is often challenged; the underlying methodology is basically anecdotal.
Impact of Security breaches
Attacker MotivationAs with physical security, the motivations for breaches of computer security vary between attackers. Some are thrill-seekers or vandals, others are activists or criminals looking for financial gain.

Secure Your Computer• Activate firewalls: Firewall are the first line of
cyber defense; they block connections to unknown or bogus sites and will keep out some types of viruses and hackers.
• Use Anti-virus/ malware Software: Prevent viruses from infecting your computer by installing and regularly updating anti-virus software.
• Block Spyware attacks: Prevent spyware from in filtering your computer by installing and updating anti-spyware software.
Be Social –Media SavvyMake sure your social networking profiles (e.g. Facebook, Twitter, YouTube, MSN, etc.) are set to private. Check your security settings. Be careful what information you post online. Once it is on the Internet, it is there forever!
Secure your mobile deviceBe aware that your mobile device is vulnerable to viruses and hackers. Download applications from trusted sources.
Install the latest operating system updates
Keep your applications and operating system (e.g. Windows, Mac, Linux) current with the latest system updates. Turn on automatic updates to prevent potential attacks on older software.
Protect your Data Use encryption for your most sensitive files such as tax returns or financial records, make regular back-ups of all your important data, and store it in another location.
Secure your wireless network Wi-Fi (wireless) networks at home are vulnerable to intrusion if they are not properly secured. Review and modify default settings. Public Wi-Fi, “Hot Spots”, are also vulnerable. Avoid conducting financial or corporate transactions on these networks.
Protect your e-identityBe cautious when giving out personal information such as your name, address, phone number or financial information on the Internet. Make sure that websites are secure (e.g. when making online purchases) or that you’ve enabled privacy settings (e.g. when accessing/using social networking sites).
Avoid being scammed Always think before you click on a link or file of unknown origin. Don’t feel pressured by any emails. Check the source of the message. When in doubt, verify the source. Never reply to emails that ask you to verify your information or confirm your user ID or password.
Call the right person for help Don’t panic! If you are a victim, if you encounter illegal Internet content (e.g. child exploitation) or if you suspect a computer crime, identity theft or a commercial scam, report this to your local police. If you need help with maintenance or software installation on your computer, consult with your service provider or a certified computer technician.
