Web security is a vast field that encompasses many facets. These include, but aren’t limited to, protection against viruses, spyware, adware, key-loggers, email or IM spam, social engineering attacks designed to force the user to make irrational decisions, spoofing, fraudulent websites, malicious tracking cookies, phishing attacks, and computer hacks. As you can see, the area grows vast if you delve deep into it. This guide will briefly describe a few of these facets.
The value of web security can’t be understated. A virus attack may create your office/home PC inoperable. You might even lose significant data which cannot be retrieved. Imagine losing a significant office record or any cherished images of friends and loved ones. Spywares, adware, malicious cookie and key-loggers can track your internet usage and steal personal information from your PC that might include credit card information and passwords. Email spam, spoofing, and hacking can do the same. To protect from these attacks, many commercial/free goods are available. Given below is a brief summary of what security applications are available.
The most famous web threats are viruses and thanks to their very nature, they could spread through removable media and local networks also. To put it simply, viruses are pieces of code that damage your computer and/or make it vulnerable to more malicious attacks. Many anti-virus solutions from several vendors exist today on the market. These can be available as complete security suites or as standalone products. These products may also detect other malicious software like spyware and adware.
Another important part of the software is a firewall/program checker mix. Basically a firewall checks the information that is sent or received by your PC from the Internet or LAN. The program checker part of the firewall checks/authorizes applications that access the internet. This component also tracks system-level changes made from the said applications.
Other significant types of web security applications include:
- Phishing filters: which checks for fraudulent websites as you browse the internet and warns you if such a website is detected.
- Anti-Spam filters: these check your mails and discover fraudulent, improper and/or other undesirable content on your email and block them.
- Ad-Blockers: Advertising may be malicious (or may lead to malicious websites ). They also hog bandwidth as a result of their flash-based and/or picture-based character.
- Other tools: These largely rate sites based on consumer reviews and supply a statistical average of the overall”trustworthiness” of the website. Mostly available in the kind of addons to web browsers.
However, the Best way of safely browsing the web can simply be summed up as follows:
- Never see un-trusted websites. Secure websites normally have a certification to prevent data from being spoofed.
- Never download software or alternative documents from untrusted sources. Software from respectable businesses can also be digitally signed.
- Emails from un-trusted resources should be opened with caution. An email that’s most likely spam should not be opened.
- Install the suitable applications as described above to further increase your PC’s security.
- Always keep the aforementioned software current.
- Unless required, keep your computer offline.
But, even after following all these steps, no computer is going to be 100% secure. There’ll always be a new virus or even an ingenious method which could be used to break into or damage a PC. Backing up your data is the last and the most important thing which may be taken.
