• Definition: Cyber bullying is the use of electronical devices such as pc’s and mobile phone to send imitating and threatening messages to a certain individual.                                                                                                                Source
• Here are some tips that I found on how to stop cyberbullying:
• First you need to know that it is not your fault that you are being Cyberbullied.
• Secondly You must know that you should tell someone and not respond or retaliate to the mean messages.
• Lastly make sure to save the evidence so you have proof that it happened.
• Tell the person to stop. This is completely up to you – don’t do it if you don’t feel totally comfortable doing it, because you need to make your position completely clear that you will not stand for this treatment any more. You may need to practice beforehand with someone you trust, like a parent or good friend.
• Reach out for help – especially if the behavior’s really getting to you. You deserve backup. See if there’s someone who can listen, help you process what’s going on and work through it – a friend, relative or maybe an adult you trust.
• Protect your accounts. Don’t share your passwords with anyone – even your closest friends, who may not be close forever – and password-protect your phone so no one can use it to impersonate you. Ensure you keep your PC up to date with the latest anti-virus software.

There are a couple of online payments which include paypal and credit card. Paypal is a very safe way of paying for items online for the following reasons. If you buy an item off ebay and it’s a scam page paypal will refund you the money straight away. If your account is hacked they can only take what amount you have in and no more, although paypal is very secure so it would be hard for a hacker to get into your account. Online payments is part of internet security. A lot of the time social engineering is used to get peoples  money online.

Using a credit card to buy online items is as easy as putting in a couple of numbers on a card and you are done, but using a credit card online can be very dangerous as hackers can get your information and take all of your money.

Most common of social engineers is to focus on the behaviours and forms of employees with low level but opening access, such as a security guard or receptionist. Some Hackers can take photograph the person’s social media profiles for information and watching their conversation online and listen to their talking. (Anderson, Ross J, 2008)

For example, the attacker might pretend to be an employer who has a crucial problem that needs access to added network resources.

Types of social engineering:

Anti-Virus

Anti-virus is a system that scans and destroys a virus that infiltrates the computer that is being used. While many antiviruses exist, their main purpose is to protect the computer from viruses and remove them if found. Some anti-viruses include an automatic and a manual scan feature. The automatic scans downloaded files from the internet and can scan disk and USB’s that are put into the computer. As well the automatic feature can be used to scan your hard drive on an annual basis of maybe a day.

The manual feature allows you to scan individual files or your entire system if deem necessary.

Since hackers will constantly update their viruses so do the anti-virus producers, releasing updates as soon as a new virus type is found. An anti-virus must be up to date, so the software automatically updates the system to tell the main system about this new virus.

Some Anti-virus software’s block or prevent other things like malware such as spyware adware and rootkits. But usually are bundled with a firewall, this is all for internet security.
