You may not realize it, but you are a target. Your computer, your work and personal accounts and your information are all highly valuable to cyber criminals. Be mindful that bad guys are out to get you.
A password is only as secure as the computer or network it is used on. As such, never log in to a sensitive account from a public computer, such as computers in a cyber cafe, hotel lobby or conference hall. Bad guys target public computers such as these and infect them on purpose. The moment you type your password on an infected computer, these cyber criminals can harvest your passwords. If you have no choice but to use a public computer, change your password at the next available opportunity you have access to a trusted computer.
Only install mobile apps from trusted places, and always double-check the privacy settings to ensure you are not giving away too much information.
Never give your password to someone over the phone. If someone calls you and asks for your password while saying they are from the Help Desk or Tech Support team, it is an attacker attempting to gain access to your account.
Two-step verification is one of the best steps you can take to secure any account. Two-step verification is when you require both a password and code sent to or generated by your mobile device. Examples of services that support two-step verification include Gmail, Dropbox and Twitter.
The number one step for protecting your mobile device is making sure it has a strong passcode or password lock on it so only you can access it.
When you delete a file, that file is actually still on your computer. The only way you can truly and securely remove a file is by wiping it or using some type of secure deletion.
One of the most effective steps you can take to protect your cloud account is to make sure you are using two-step verification. In addition, always be sure you know exactly whom you are sharing files with. It is very easy to accidently share your files with the entire Internet when you think you are only sharing them with specific individuals.
Eventually, we all have an accident or get hacked. And when we do, backups are often the only way to recover. Backups are cheap and easy; make sure you are backing up all of your personal information (such as family photos) on a regular basis.
When shopping online, always use your credit cards instead of a debit card. If any fraud happens, it is far easier to recover your money from a credit card transaction. Gift cards and one-time-use credit card numbers are even more secure.
Never send an email when you are angry; you will most likely regret it later. Instead, when you are emotional and want to reply to someone, open up an email and write everything you feel, but do not send it. (Be sure there is no name in the TO field so that you do not accidently send it.) After you have vented, save the email and come back an hour later. You only want to reply to any type of emotional situation after you have had time to cool down.
Review your bank, credit card and financial statements regularly to identify unauthorized activity. This is one of the most effective ways to quickly detect if your bank account, credit card or identity has been compromised.
Make sure each of your accounts has a separate, unique password. Can't remember all of your passwords/passphrases? Consider using a password manager to securely store all of them for you.
CEO Fraud is a type of targeted attack. It commonly involves a cyber criminally pretending to be your boss, then tricking or fooling you into sending the criminal highly sensitive information or initiating a wire transfer. Be highly suspicious of any emails demanding immediate action and/or asking you to bypass any security procedures.
When a major news event happens, cyber criminals will take advantage of the incident and send phishing emails with a subject line related to the event. These phishing emails often include a link to malicious websites, an infected attachment or are a scam designed to trick you out of your money.
One of the most effective methods you can use to protect kids online is to talk to them. The younger you start talking to them, and they to you, the better. Hold regular conversations about online safety issues, even going so far as to show them actual negative events that have taken place. If you don't know what your kids are doing, simply ask. Play the clueless parent and ask them to show you what the latest technologies are and how they use them. Quite often, kids love the idea of being the teacher and will open up.
Be careful: the more information you post online about yourself, the easier it is for a cyber attacker to target you and create custom attacks against you or your organization.
Make sure you have anti-virus software installed on your computer and that it is automatically updating. However, keep in mind that no anti-virus can catch all malware; your computer can still be infected. That is why it's so important you use common sense and be wary of any messages that seem odd or suspicious.
Ransomware is a special type of malware. Once it infected your computer, it encrypts all of your files and demands you pay a ransome if you want your files back. Be suspicious of any emails trying to trick you into opening infected attachments or click on malicious links, common sense is your best defense. In addition. backups are often the only way you can recover from ransomware.
