- Learn How To Secure Browser?
Today, the most popular desktop browsers are Chrome, Safari and Firefox and Opera. While most commonly used to access information on the web, a browser can also be used to access information hosted on Web servers in private networks.
Plugins and Extensions
Although not part of the browser per se, browser plugins and extensions extend the attack surface, exposing vulnerabilities in Adobe Flash Player, Adobe (Acrobat) Reader, Java plugin, and ActiveX that are commonly exploited.
Malware may also be implemented as a browser extension, such as a browser helper object in the case of Internet Explorer. Browsers like Google Chrome and Mozilla Firefox can block—or warn users of—insecure plugins.
By using Camera/Microphone usage
We need to block from running it automatically or have the browser ask you each time a website wants to use the camera or microphone. Only allow for trustworthy web or applications.

- NoScript or ScriptSafe: Popular programs that block scripts on websites until the user specifically enables them
- Flashblock: An add-on that prevents Flash ads from playing until the user specifically allows them
- HTTPS Everywhere: An add-on jointly created by the Electronic Frontier Foundation and The Tor Project that encrypts your web browsing traffic
Browsers can use more secure methods of network communication to help prevent some of these attacks:
DNS: DNSSec and DNSCrypt, for example with non-default DNS servers such as Google Public DNS or OpenDNS.
HTTP: HTTP Secure and SPDY with digitally signed public key certificates or Extended Validation Certificates.
Browsing the Internet as a least-privilege user account (i.e. without administrator privileges) limits the ability of a security exploit in a web browser from compromising the whole operating system.
Suspected malware sites reported to Google, and confirmed by Google, are flagged as hosting malware in certain browsers.
Need To Know?
Always check HTTPS for Top Websites. HTTPS is encryption layer used to secure against attackers with access to the network from changing the page contents en route.
For normal password usage on the WWW, when the user is confronted by a dialog asking for their password, they are supposed to look at the address bar to determine whether the domain name in the address bar is the correct place to send the password.
For example: If you are surfing Bank websites, always check HTTPS sign-on system (used on e.g. anybank.com), the user should always check that the address bar says “https://anybank.com” before entering your password id.
