A lot of people do not have a clear idea of what an information security professional actually does. The lack of understanding also gives rise to certain misconceptions regarding this profession. If you are thinking of becoming an information security professional, you would first need to learn what information security is all about.
To say simply, information security refers to the process that protects the privacy, integrity and availability of data. The term primarily refers to the methods and measures that are ensured for improving computer security. However, it may also refer to the process of protecting any sort of important data including personal diaries and so on.
It is hard to find a security system that is foolproof. It is, however, possible to take the basic and practical steps for ensuring that the critical data is safe. This is what a competent information security professional does. Here are some of the aspects of this profession that you must know about:
One of the basic methods of increasing information security is to use password. Using password makes it possible to reduce the possibility of data theft. When particular information is easily accessible to all, data theft is common. Using password restricts access to that particular information, and thus, only a handful of a people can get their hands on the data. Once the password is placed, only those who know the password can obtain the information.
However, it is important to know that even passwords are not foolproof and the advanced hacking programs can work through billions of possible codes within seconds. Passwords are often breached due to carelessness. For example, many people make the mistake of keeping a public computer logged into their private accounts. Simple codes like “1234” or “password” are also easy to figure out. That is why you must never use such simple codes as passwords.
In order to create secure access, you need to create passwords using lower and uppercase letters, symbols, and numbers. You must try to avoid combinations that can be guessed easily. Such combinations may include birthdays or the names of family members and so on. You must never note down passwords on a paper that is kept right beside the computer. It is also vital that you have different passwords for different accounts. It is also a great idea to change the passwords every few months. This way better security can be ensured.
Malware protection and antivirus:
Hackers obtain secure information through malware. Malware is malicious software that is developed with the purpose of harming computers. This may include computer virus, worms, spyware as well as other programs. If these codes are installed in a computer, stealing information off that computer becomes easy. Other than stealing information, these programs also help hackers to record user’s actions, limit usability of the system, and destroy data. One of the best ways of improving information security is to use strong antivirus software.
Once you have an antivirus program in place, it will scan the system in order to make sure that there are no known malware present in the system. The antivirus will also warn the user when he/she is on a virus infected web page. The whole system can get affected by virus if you open such a webpage. Most of the antivirus programs can also perform regular scans of the system. Such programs can also identify and destroy harmful objects on command.
