A few days back I wrote down one article about How good is your internet security against Ransomware, after publishing this article my many subscribers asked me about How to check PC Security? how to check PC firewall is working or no? so I decided to write one complete article about it and I am trying to cover approx all expects of this heading.
Check if your accounts have been breached
If you suspect that you may have fallen victim to a hack, visit Have I Been Pwned? (haveibeenpwned.com), which catalogs all the email addresses and other data taken in high-profile breaches.
Enter your email address in the search box and if it’s found in the data dumps, a red warning will appear, revealing what was taken in the hack and recommending you change your password(s) immediately.
You can also sign up for notifications of future breaches. At the time of writing, Have I Been Pwned? featured more than 4.7 million ‘pwned’ accounts and 232 ‘pwned’ websites, including MySpace, Adobe and LinkedIn.
Test the strength of your passwords
There are lots of online tools that test the strength of your passwords, but make sure you use one that encrypts what you enter or you could actually be risking your security.
Our favorite is the Dashlane-sponsored How Secure Is My Password?(howsecureismypassword.net), which tells you how long your password would take a hacker to crack.
If the answer is less than a minute, you should change the password as soon as possible.
Ensure your security software is working
Don’t let malware infection be the first sign of a security hole. The AntiMalware Testing Standards Organization (AMTSO, www.amtso.org) offers a Security Features Check that exposes potential weaknesses in your system’s defenses.
The check consists of six tests, four of which involve downloading files that your PC should identify as malware and block automatically.
These files aren’t actually malicious but are designed to be detected as such, so if your anti-malware program lets one through, then you need to tighten your security settings.
Test your firewall for weaknesses
Firewalls generally run quietly in the background, so it’s important to know that they’re working properly.
To test yours, try to bypass it using the free online port scanner GRC ShieldsUP (www.grc.com/shieldsup). Ports should be closed.
by default, apart from port 80 (or 443), which is needed for web traffic. You can choose to test either Common Ports (only the most vulnerable ports) or All Service Ports (a thorough scan of 1,056 ports). Green or blue results mean that those ports are secure, while red ones show open ports that need to be closed.
Make sure your plugins are up to date
Security holes in Java, Adobe Reader, and Flash put your personal data at risk, so ensure your plugins are up to date by using Qualys BrowserCheck (browsercheck.qualys.com).
This scans your browser and its plugins to detect outdated versions and other security
problems. Click the Fix It button next to scan results marked as ‘insecure version’
or ‘update available’ to install the required updates. The test works with
all major browsers.
TEST YOUR OWN SECURITY KNOWLEDGE
Avoid being the weak link in your PC’s protection by keeping your cybersecurity knowledge up to scratch.
