“PREVENTION FROM HACKERS”
Ammarah Khalid
Some common ways to prevent your device
from being hacked are:
1) OS Updates
2) Software Updates
3) Installing Anti-Virus Software
4) Installing Anti-Spyware Software
5) Stop using Hacker Controlled Websites
6) Use Firewall
7) Data Backup
8) Avoid Spam Emails
9) Password Policies
10) Clear the Cookies
11) Don’t use generic user names
12) Keep your identity safe
Operating System Updates:
Hackers attack:
• Where they find weakness.
• A system ( not updated ) has flaws.
• So update your system regularly.
Software Updates:
Get the latest fixes or versions of :
• Applications installed on your computer
• Web based software
Installing Anti-Virus Software:
Install anti-virus software as soon as you can, and always
confirm if its virus definitions are regularly updated.
Installing Anti-Spyware Software:
A type of intrusion that:
• Slows down your computer
• Put advertisements
• Put pop-ups on the screen
• And can lead to identity theft
• So install anti-spyware as
soon as possible!
Stop using Hacker Controlled Websites:
In World Wide Web, avoid from:
1) Sites containing free downloads.
2) Online games.
“They are mostly controlled by hackers!”
Continue..
For ensuring a secure website:
• Check site-lock sign on Title bar
• https:// is written in caption below the title bar
instead of http://
Use Firewall:
Firewalls forbids:
• Outside threats (i.e. from hackers)
• Viruses from gaining access to your system.
• Control the traffic across connection
• Personalize your firewall settings
• Update it regularly
Continue.. (FIREWALL)
Data Backup:
The sensitive bits of
information can be wiped
clean from your hard
drive in the blink of an
eye..
“So it's best to always
have a backup at hand”.
Avoid Spam Emails:
Never click on an emailed link that looks
questionable. Delete them!
Password Policies:
Use:
• Multiple, intricate passwords
• Combinations of letters and numbers
• Make sure that your password is not too difficult for you to
remember it!
Clear the Cookies:
Do not forget to
clear the cookies
and cache before
you leave!
Don’t use generic user names:
Do not use usernames such as:
• admin
• administrator
• Site Owner
Try to use unlimited range of combinations for
names.
Keep your Identity Safe
1) Do not use official email ID to subscribe
to the public groups.
2) Do not share and post professional
information on Social networks.
“Learn new technologies and techniques
for protection against hackers and keep
aware! “
