Computer threats are ubiquitous and take many forms: viruses, cyber harassment, data theft, distribution of sensitive files, ransomware, revenge porn… The democratization of Internet uses increases the risks insofar as there are more exploitable flaws. by hackers. Fortunately, it is possible to protect yourself from the majority of these dangers.
Install a powerful security suite
It may seem obvious, yet many users overlook antivirus solutions. The installation of reliable and efficient software is undeniably the first reflex to adopt to guard against computer dangers.
When you connect a mobile device (USB key, SD card, etc.) to transfer files, viruses and malware can take advantage of the connection to infect the files. It is therefore imperative to prevent potential attacks. For example, thefree antivirus from avira Blocks malware such as Trojans, viruses and ransomwarebut not only.
Internet browsing is also a risk vector. The danger is all the greater when the site consulted offers access to personal and sensitive information. Online banks and social networks require special vigilance. E-commerce sites and emails should also prompt caution. Certainly, trusted sites like those of financial institutions are subject to strict security protocols. However, the hackers are sometimes able to circumvent them. With a comprehensive antivirus suite, it is possible to block access to infected sites and protect against the Phishingamong other threats.
At the same time, it is essential to regularly update the operating system and the various software installed. Outdated programs are more vulnerable to computer attacks.
Strengthen security on public networks
While ensuring the security of personal devices and networks is essential, it is even more important to take careful precautions before using public Wi-Fi networks. These networks are practical because they simplify Internet access in airports, libraries, restaurants, public transport, etc. In many cases, the connection is done automatically, without authentication. It is precisely this flaw that cybercriminals exploit to access, steal and/or compromise user data.
The use of a VPN (virtual private network) is highly recommended. Data is encrypted from the time it leaves the device until it arrives at the VPN provider’s server and vice versa. Activities on the Internet therefore leave no exploitable trace for malicious people. In the event that hackers were able to hack the device, they would only be able to access encrypted data.
It should be kept in mind that the VPN network is not infallible even if it considerably increases security. It is therefore essential to install a complete and up-to-date antivirus suite in order to block threats in an optimal way.
It is also advisable to only use public Wi-Fi networks that use an authentication system.
Adopt good browsing habits
Excessive caution is preferable to negligence, especially since computer threats continue to multiply.
It is recommended to deactivate the automatic connection function to Wi-Fi. It is thus possible to control the networks used and to limit the risks of exposure to computer attacks. When going through a public network, it is essential to disconnect as soon as the navigation is finished to prevent hackers from creating their own access point.
Following the same logic, it is more prudent to avoid the use of public networks to consult sensitive sites. Indeed, it only takes a few seconds or a few minutes to check the balance of an online bank account or to carry out a financial transaction, for example. However, it takes less time for hackers to collect data that they could use for fraudulent purposes.
Regular backup of files is still necessary even if all security provisions are already adopted. In the majority of cases, the removal of malware infected programs and files is necessary. Without a backup, all data will be permanently lost. The use of external storage devices protected by an antivirus is therefore desirable.
Particular attention will be paid to the choice of passwords, whether those that secure devices or those that provide access to personal spaces on the Internet. The golden rule is never to choose an obvious password such as first name or date of birth. It is better to favor complex combinations (upper/lower case letters, special characters, numbers, etc.) and adopt a password of at least 10 characters. Also, it is important to assign a specific password to each device and site.
Yes, cybercrime is on the rise and yes, attacks can harm victims. However, it is possible to reduce the risks through good habits and effective software solutions.
