The Internet is a big part of our lives nowadays. We go on the Internet for shopping, job applications, business networking, researching genealogy, social networking and finding old friends through social networking sites, downloading music, and taking a course. You name it, the Intenet has it. If you need to receive or send information, the Internet offers some avenue to help you do the task. Yet as usage of the Internet becomes more widespread, the rate of Internet-related crimes increases.
Computer crime is one the fastest growing crimes in the world. Companies have taken precautions to safeguard themselves against computer hackers. The following are ways that companies use to protect themselves against hacking.
- Install powerful Anti-Virus and Firewall software. One of the ways that computer hackers infiltrate a computer system is to send a key-logger virus. These are Trojan horse viruses, which if successfully installed on your system without your knowledge, will grant easy access to your personal information. It will keep track of all keys pressed on your keyboard. If the hacker knows the security password of your computer, it will be easier for him to hack the system. Installing a good Anti-Virus and Firewall will protect your computer from these types of attacks. One thing to remember is to always update your anti-virus program to insure maximum security possible.
- Encrypt files and lock up documents. Any important record or file should always be password protected or stored in encrypted files. This will protect your files against unauthorized access through the computer. Remember to use strong and secured passwords very difficult to crack. Use varying combinations of upper and lower case characters along with numbers.
- Do not open suspicious emails. Most viruses cannot inflict damage to your computer system unless you open the mail attachment that includes the virus. The email may appear to be from a friend or colleague or have an appealing file name. Do not open or download file attachments unless you are 100 percent sure.
- Back up important files. It is a good practice to always have a back up copy of your important files. No system is completely secure, and if a virus or a hacker successfully penetrates your system and deletes all files, you will still have your backed up files.
- Use Spam Filters. Unsolicited mail is a form of spam, and it is one of the biggest problems when it comes to online activities. Using a spam filter, you can have your computer's system protected from phishing schemes before they reach your mailbox. These spam messages can sometimes contain a virus, which when clicked will automatically enter your system without your knowledge. Spam filters allow you to remove incoming spam messages.
- Turn off your computer, and disconnect from the Internet when not in use. The hacker cannot disrupt the system of your computer while your computer is off.
- Think like a hacker. This way, you can defend your network against hackers. Companies usually have computer experts and programmers to create their own version of security system and also to develop countermeasures for possible future attacks.
