Earlier sections have at where there are vulnerabilities in computer systems and some of the actions you can take reduce the risks of attack.
This section is concerned with how you can reduce the risks even further through the information you release online, particularly through the social media.
Before signing up to a social media site, research your possible options. Check out:-
Get familiar with the privacy settings of your social media site.
Social media users commonly make two mistakes, both of which increase the risk of becoming a target.
Really check out the privacy settings. In Facebook there are multiple categories where privacy settings need to be set. You should hide yourself from search engines to prevent strangers from finding your page.
Also make sure your social media site doesn't give out information to companies. In Facebook you have to deny permission for Facebook to do this, together with the setting appropriate permissions for adverts. Otherwise you can become a target for companies and 'click-bait' adverts.
Consider the amount of personal information made visible on social media sites. At the very least don't:-
Social media is very convenient to keep up with your mates, but in doing so, you expose yourself to some risks.
Assume that 'What goes on social media, stays on social media.' Once posted on the internet, all control about what you've said is lost. Once in the wild you have no idea how someone may interpret it or use it, either accidentally or deliberately. So:-
Good reputations are difficult to build and are very easy to lose. So checkout :-
Using social media can be a good thing. It's always good to share. But you have to be active in keeping people out of your account. Some of what follows appears obvious but its surprising how many people fail at the first hurdle.
Social media sites are frequent targets of malware attacks. They're are after all, 'target rich' meaning you might not get them all but you will find a weakness somewhere in someone that you can exploit as a hacker.
So make sure you computer is up-to date and has good anti-virus protection.
Precautions can be taken to guard against attack by using firewalls, keeping software up to date, selecting the best hardware and software settings to keep yourself safe and so on. But you also have to be careful about the information you release into the wider world.
Inadvertently you may be releasing clues about yourself that could be helpful to an attacker. Your pet names, favourite band may be clues to your password.
Don't forget, social media also includes sites like Instagram and Twitter. And you certainly don't want to appear less than sharp on those .... do you?
Using Social Media involves revealing and sharing information in posts, but too much information is a bad thing.
Imagine you have to give advice to a social media 'noob':
Time to learn another hacking method - Screen Scraping.
This method is extremely useful for capturing large amounts of data from websites, which can then be taken away and analysed. There are many programs around for screen scraping, which allow you to write 'bots' or 'crawlers' which automate the system of going out onto the internet to capture data being looked for.
Companies use them, amongst other things, for analysing what's going on in the market (e.g... discovering who selling what and for what price). Hackers can use them for gathering large amounts of personal data and see if they can discover weaknesses that can be exploited.
In this exercise screen scraping is being used to gather data in response to a simple query.
If you had success, then BOOM! ... another hacking technique completed. Although you did this with a commercial site, imagine how you could apply this technique to a social media site.
Try a bit of research on google, if you can't ...
Before you try this, you will need to create a google account. And then use this to create an account at Portia Scraping Hub
If you don't feel confident in meeting any of these performance criteria, ask your teacher or re-read the information again.
