Passwords are the main authentication method used for internet sites and applications. But passwords get stolen and have many weaknesses Here are tips you can use at home and at work to protect your information.
How to choose a password that’s hard to crackKlaus Drosch
A good password is usually the first and only line of defense for your important web-services. Choosing a strong and memorable password can be a hassle since those two criteria don’t always go hand in hand. It’s tempting to reuse an old password, slightly modifying it, or even write it down on a text-file in the computer.
In this guide, we will show you how to choose a good password, how to remember it and just how easily bad passwords can get hacked.
Why is password protection a fallacy a point of viewYury Chemerkin
MAKE your password strong, with a unique jumble of letters, numbers and punctuation marks. But memorize it – never write it down. And, oh yes, change it every few months. These instructions are supposed to protect us. But they don’t.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks
How to Protect Yourself From Heartbleed Security Flaw
1. How to Protect Yourself
From Heartbleed
Security Flaw
Larry Magid
Co-director
ConnectSafely.org
April 11, 2014
2. Don’t panic
• It’s a serious problem but it’s not the end of the Internet as
we know it
• Flaw has been around for two years
• So far (as of 4/11/14) there are no reports of the flaw being
exploited
• Hardware could be vulnerable but not clear if consumer
routers are at risk
3. See if the sites you visit are vulnerable
• Check to see if sites you visit are now vulnerable*, using:
• Lastpass Heartbleed checker
• Filippo Valsorda's Hearbleed test
• Qualys SSL Labs
• Also check CNET’s list of top 100 sites
* The fact that a site is now vulnerable doesn’t mean it wasn’t in the past
4. Change passwords once you know
your site is not vulnerable
• After confirming that a site is not vulnerable, change the
password
• Actually you should do this regularly – at least every few
months
• Keep reading for advice on how to change your passwords
5. Monitor your accounts & watch for
phishing
• Check your accounts
• Check your email, bank, social media and other accounts to make sure
there is no irregular or suspicious activity or unauthorized purchases
• Beware of “phishing attacks”
• You might get email that appears to be from banks and other sites,
"disclosing" that the site was vulnerable and asking users to reset their
passwords. These could be phishing attacks designed to trick you into
revealing your log-on credentials to thieves. And some of these attacks are
very sophisticated, taking you to sites that look identical to a company's
real site
6. Change your passwords once you
know the site isn’t vulnerable
• Change your passwords after you know that the site isn't vulnerable
• If you change them on currently vulnerable sites you’ll have to do it again
with another unique password
Read on for password suggestions
7. Passwords should be:
• At least 8 characters long
• Contain at least one number
• Contain at least one capital letter
• Contain at least one symbol (like #, %, &)
• Not be a real word, name or anything that would be relatively easy to
guess
Go to next slide for suggestions
8. Think of a phrase you can remember
Come up with a phrase and use a character from each word. Use
capitals where appropriate
Example
“I met Susan Morris at Lincoln High School in 1991”
The password could be: ImSMaLHSi#91
9. An easy way to make each password
unique
• Add a letter or two to the password based on the name of the site
you’re logging into. For example:
• Amazon: aImSMaLHSi#91z (added an A to beginning and a z to end)
• Google: gImSMaLHSi#91
• Twitter: tImSMaLHSi#91r
10. Change your passwords if & when:
• There has been any type of security breach on the site or your system
• You have lost a device that has the password stored
• Someone else gets hold of your password
• And even if none of this happens, change your passwords every few months
11. Consider 2-factor authentication
• A growing number of sites allow you to use two-factor
authentication: Something you know & something you have.
• Typically, the site will send a code to your phone that you type in
along with your username and password. Anyone trying to access
your site without your phone is out of luck.
• Some sites (like Google) only require it if you’re on a new device.
Others require it each time.
• Downsides are it’s a little inconvenient and a hassle if you don’t have
your phone
• Upside: It’s a lot more secure (but not 100% secure)
12. Be wary of tricks to get your password
Avoid phishing: Never enter a password based on a link in an email
unless you’re absolutely sure it’s legitimate. It’s safer to type in the web
address of your bank or other company rather than clicking on a link.
Don’t give out password over phone: Be skeptical if you get a call from
a service you use or your company’s network support department
asking for a password. Tell them you’ll call them back and find out if it’s
legitimate.
13. Consider using a password manager
• Password managers store and enter passwords for you. You can
create really strong passwords (or let them generate random ones)
and all you need to remember is the password manager’s password
• Examples:
Lastpass
Roboform
Kaspersky Password Manager
DataVault Password Manager (iPhone)
mSecure Password Manger (Android)
14. Use a very strong password for:
• Email
• Many sites will send your password to your email address so it’s important
that it be very secure
• Social network sites
• Your reputation can be affected if someone posts negative and abusive
material in your name
• Banking
• Pretty much goes without saying that you want a strong lock on your bank
account
• E-commerce sites
• Don’t let anyone go on a shopping spree with your money
15. Never share your passwords
Sharing a password is not a sign of being a good friend. Even if you
really trust that person:
• A friend can become an ex-friend
• Your friend might not be as careful as you are
• Your friend might use the password on a machine that’s not all that secure
• Possible exceptions are kids sharing with parents or spouses sharing with
each other
