How to be more secure online: Best tips
Study the threat
Learn attack vectors and hacking techniques. Study security bulletins, computer tips and tricks on online security. Keep in mind that most attacks are done via browser and software launched inside of it, such as Adobe Flash. Other types are done via mail. Imagine that you get an email with an attachment that looks like a PDF file but has an .exe extension. You click on it and install malware. Therefore, the best advice is to be careful when you open the files sent by anyone.
Know three categories of attacks
1. Low-Risk Attacks
They do not aim at stealing money or data. To eliminate the nuisance they may cause, train your employees to notice their signs:
- Antivirus software suddenly becomes disabled and fake antivirus messages appear
- Unknown toolbars appear in the browser
- Strange emails are received
- Unknown programs are found in the control panel list
2. Higher-Risk Attacks
They add your computer to a botnet, thus making it a part of the network of criminal enterprises involved in stealing money and data. You may notice this attack if you cannot access some websites due to a password change.
Checking whether you PC has really become a part of a botnet can be difficult. To prevent such attacks, reinstall the operating systems in your network twice a year and use firewall logs and TCP View.
3. Critical-Risk Attacks
They are usually made to get an access to your databases and steal your money or data. To detect this attack, use security monitoring system. Also, watch out for such events as:
Ftp running on your computer
Noticing that somebody received increased privileges or logged into a service account
Change in the DNS settings
Withdrawal of money from your bank account
Consider all of these basic security measures and teach your employees to detect attacks. If you keep your software constantly updated and remain attentive to everything you see on your computer, you can prevent any damage.
