With the rise in threat vectors proliferating in the environment, corporations, banks and retail outlets online need to be careful to ensure their sites are secure.

There are many ways hackers can get in and target everyday people, be it through social engineering or targeted attacks.

Social media is all pervasive these days and some people have multiple accounts on different platforms. To ensure you keep sensitive information off these sites, reveal the least amount of information, post to friends only and be careful who you friend. Social media sites can be hacked and some are prone to viruses. If you don’t know a person think carefully before accepting them as a friend. Also keep passwords for social media accounts secure and don’t share them, use strong passwords.

For other sites that hold more sensitive information ensure you us a unique username and password for these sites, which could include financial sites. Don’t share the same password across sites. Use a password that is 8 or more characters long with special symbols, numbers, letters and no repeating characters. Also use a combination of upper and lowercase letters.

If you are looking for a job through social media sites that are set up or career networking be careful what information you expose. Some of these sites allow anyone to see your information. A hacker can find out a lot about where you work, your skillset and employment status using tool hackers have access to that crawl the web. These sites are also useful for hackers who use elicitation a form of social engineering for information gathering to track a target. Sometimes hackers target people in certain positions to find ways to infiltrate companies, or gain proprietary information.

For email, phishing is an easy way to target unsuspecting people. These emails might try to get you to click on a link that will download a virus to your system.

Always be wary about clicking on links in email if you do not know the sender. Look at the sender’s address as it is easy to spoof an email address. Spam domain blocker tools also exist that can block whole domains. Most email hosts have a form of these tools to help protect you.

Virus scanning systems that protect from viruses are also good tools to employ. Keep the scanning software up to date to receive the latest patches These tools can also scan your system and block malicious websites. It is also good to have a strong firewall.

Again some of these practices rely on the human equations. If you don’t know if something looks legitimate be wary.

Your internet connection can also be targeted. Be careful about using public WIFI and only use trusted connections. Your coffee shop’s WIFI may be free but there might be hackers in the vicinity with similar WIFI connections that will steal your information if you connect to them.

Hackers use key stroke logging systems that can log your keystrokes once in or infected and can easily get your information.
