securing Website from HACKERS !!!
Hello folks,
As the Bitwise site is up now, I am trying to gather as much information as possible related to website hacking. Went through many articles, I am still running my search engine to know more ;) this article is a good one.
There are times when having a website of your own becomes inevitable. You can use it to be able to reach as many target customers as possible. After all, they are located in almost many parts of the world. You can display all your products and services in your website. But do you know that they can be a great area for hackers to play on? So how can you protect your website against hacking?
1. Protect your files with passwords. Surely, your website will contain scripts, database, and files that are not meant to be shared publicly but for perhaps the search engine bots. To avoid having anyone getting hold of them, it may be ideal to protect them with password. However, you have to make sure that these are very hard to decipher. This is because they can simply make use of a password-deciphering software. You can combine alphanumeric characters and exhaust all the character limits as much as possible.
2. Secure your e-mail address. There may be times when you will be receiving an e-mail address courtesy of your online business form. There are even others who will send a message directly into your mailbox. This may mean that spammers have got hold of your contact information perhaps in the Web or from someone else. To prevent this, you can make use of software that will split your e-mail address. It will then very hard for spamming software to read. You can also just add an E-mail Us link into your website or an image which can be clicked and allow your customers to send an e-mail right away. There’s no need to reveal the e-mail address.
3. Don’t leave e-mail addresses anywhere. Perhaps you’re thinking of marketing your website in forums and other public online networks. This is okay; however, you have to be very cautious. Hackers and spammers are very much interested of your e-mail address. You can make use of a bogus one, and simply add a link of your website in the signature.
4. Secure your source code. There are hackers who are interested in getting your source code to either destroy it or to build a website clone. That’s why it is very important that you can protect it against such individuals. You can make use of scripts that will allow your source code to remain hidden to Internet users. Or you can simply make use of external CSS sheets as well as files for Javascript.
5. Add a robot.txt. This is a special instruction you will give to search engines who may be visiting your webpages. You can instruct them to only index those files that are meant for users. You can also direct them to not index any that are only meant for webmasters. These may include files and images.
6. Check the permissions you may have set for your uploaded files. This is to prevent any hacker from getting access into your important and confidential files. You can confirm it by selecting CHMOD for your files located in the web hosting server. Otherwise, if you aren’t sure, then you can simply verify it from your webmaster.
7. Take away old or unnecessary files. It’s normal for search engines to keep files from your website, especially if they are being indexed. However, if you remove them from the server, then no one can access them anymore. It will not be obtainable for hackers and spammers.
8. Know your server. Your server is very essential as you basically keep all of your files there, and it will cause your website to run smoothly. Intruders, on the other hand, can add virus or malware into your system, thereby causing damage into your website. If you are running it on your own, you must know your server properly. This way, you can set the right security and permission level for your site.
