10 Easy Tips How To Improve Computer Security


Netgenz - Technology  Computer and Internet  How to Improve Computer Security – Some time ago we were shocked by the emergence of ransomware called wannacry which can encrypt our data, so that it is locked and cannot be opened in any way, except paying some money to the owner of the ransomware.

Even though the wannacry cyber storm has subsided, it's possible that someone out there is designing much more virulent ransomware. Hence, the issue of security in computers is now increasingly important. Not only for business people but also for students and students who use computers in their activities.

There are several ways that you can use to increase computer security. Anything?



1. Use antivirus and antispam

Have you installed antivirus? Antivirus has the function of guarding, securing, finding, and destroying viruses that threaten computer systems.

In Indonesia, the spread of the virus actually occurs more through flash. Therefore protection using antivirus is very important. No need to use expensive antivirus. Free antivirus is enough. However, there is nothing wrong with using two security systems at once, as long as their functions do not conflict.

2. Update your OS patch when available

OS or Operating System is the operating system of the computer you are using. For example Windows 7 or Windows 10.

Periodically, the OS developers add update patches for the operating system. If when you are using a computer and an update notification appears, then do an update on your OS. Every update means there are improvements, and it is possible that there are additional security improvements.

3. Use Firewall

Think of your computer as housing. So, the firewall is the security guard. The firewall is in charge of monitoring the entry and exit of data, from the internet to your computer, or from your computer to the internet. The function of this oversight is to ensure that the incoming files are safe files, and also ensure that the outgoing files are not files that are forcibly taken/stolen. If the outgoing data to the internet occur without your permission, the firewall will immediately block the process of sending the data and block the file requester.

In general, firewalls are also effective in filtering out viruses, trojans, e-mail eavesdropping, and spyware that record data input on your computer. The firewall also filters and checks incoming and outgoing data traffic, ensuring all data traffic occurs with your permission.

3. Don't log in to important accounts from public wifi

The public wifi is of course nice. You can access the internet without being deducted from your quota. However, hotspots in public places can be very risky. It is possible that someone in a public place installed data recording software, which can record the address of the site you are accessing, your username, and your password.

If you just log into your social media account, it might not be a problem. However, you should not access e-banking or e-mail accounts in public places. One mistake, your important information can be stolen, then used for their own interests.


4. Use complex password combinations

One other security tip is to use a complex password combination. If the keywords you use are vocabulary in a dictionary, such passwords will be cracked using the program in just 2 seconds. While the combination of numbers, punctuation and upper and lower case letters can only be dismantled with an estimate of about millions of years!

However, isn't it difficult to remember passwords with complex passwords?

Edward Snowden provides tips on this subject. We have to change our mindset about “password” to “passphrase”, aka key phrase. So we don't just create a password from one word, but a combination of several words, numbers, and punctuation marks.

If we create a password with a phrase, say “100%LoveFast&Furious”. This is easier to remember than “F@2t&Fur10us”. Using sentences, we have got a strong but easy-to-remember password.

5. Using ACL (Access Control List)

Another tip to improve computer security is to use ACLs. An ACL, or Access control list, is the sorting of data traffic by category. This will be crucial when you need control of data traffic.


6. Do back up regularly

The Wannacry Ransomware some time ago had the ability to lock your data until it was inaccessible. If you want to open it, you have to pay some money. Actually, this does not need to be done if you backup data regularly. Backup means copying data to a place as backup data if at any time the main data is damaged or lost. This is relatively easy to do if you subscribe to cloud-based data storage and wifi. Your data will be backed up automatically. The manual way can use a CD, DVD, or external hard drive.


7. Upgrade the operating system

If you're still using an older operating system, such as XP or Windows 7, it's a good idea to start considering changing your operating system. The reason is that the operating system has not received security updates for a long time. It is feared that the operating system you are using is vulnerable to viruses or hijacked.


8. Beware of Spyware

Spyware is a small program that can record and track the activities you do on your computer. This program is tiny, barely visible, and uses a pseudonym similar to the name of the program on the system.

Spyware is usually obtained from accessing pornographic sites, using pirated software, or installing the wrong application. However, spyware can be prevented using an antivirus or antispyware program.

9. Secure Wireless Connection (Wireless)

If at home or at work you use wifi, always set a password for your wifi. It's better if the password is changed regularly. Thus, people can not arbitrarily access your wifi.


10. Beware of emails from the spam box

In the spam email box, we often find emails as if from women who invite acquaintances. In the email, he attaches a link to an address or a program. Don't open the email! Because it is feared that the link or program contains a virus. If you do not know who the sender is and you are not waiting for an e-mail from someone else, you should not open the e-mail.
