WEB WARNING 
Web Security 
Basics
Keeping Your Computer Safe 
• The term for software with malicious intent is malware 
• The purpose of malware can be anything from simply 
spreading to as many systems as possible as a proof of 
concept, to stealing sensitive user data like credit card 
details
Keeping Your Computer Safe 
• Keeping your system up-to-date, enabling a firewall and 
regularly scanning your system for threats is the best 
way to keep malware out 
• Be on guard and always think twice before acting on 
something that seems suspicious or "too good to be 
true"
Keeping Your Computer Safe 
• Good password security is the best defense against 
hackers accessing your user accounts (and it can be 
easier accomplished through third party software)
Keeping Your Website Safe 
• Encryption is the first step in web security, both for user 
interaction and when performing administrative tasks 
• Keep the software you use up-to-date at all times, and 
remove any software/scripts you don't use to minimize 
risk
Keeping Your Website Safe 
• Be suspicious of user data, and always validate and filter 
it on the server side before processing and using it 
• Use vague error messages with little or no details to 
make information gathering harder for malicious users 
• Backup your files and databases regularly, and keep the 
backups for a long time in case you need to roll back 
after an intrusion
Keeping Your Personal Info Safe 
• Always think twice, and double-check domain name and 
encryption before submitting sensitive data online 
• Read privacy policies, even if it takes a few minutes of 
your time (and they're extremely boring!) 
• Consider restricting access to your social media profiles, 
and think twice before posting personal information
Keeping Your Personal Info Safe 
• Be suspicious if you receive a strange message from a 
friend - their account might have been hacked and now 
the hacker is trying to scam you 
• Make sure you don't leave your sensitive data readable 
on your computers, phones and other devices when 
sending them off to recycling
Top 5 Online Common Scams To Watch 
Out For 
• Top 5 Common Scams: Paypal/Online Bank phishing, 
work-from-home scams, 419 Scams (“Nigerian Letters”), 
Fake lotteries, Classified/auction scams. 
• Don't blindly trust emails that offer you money, or try to 
scare you into logging in on the website of a financial 
institution
Top 5 Online Common Scams To Watch 
Out For 
• Legit "work-from-home" opportunities exist, but be on 
guard if they claim to require little skills and actual 
work, or if you need to invest money up-front 
• Be very careful and educate yourself properly when 
buying/selling things on auction or classified sites
