At CTN News, we have consulted two cyber-security experts to give us the keys to securely using social networks, e-mail, online banking, mobile applications and even link pages.

“Apply common sense, show respect for others and be very careful when dealing with unknown people,” says Marina Nogales Fulwood, director of K2 Intelligence, a company specializing in cyber security.

“If you are not the type of person who insults strangers on the street, then you have to behave in the same way as you do in real life, do not do it on social networks! “Warns Nogales Fulwood.

Secure your accounts. “In the case of Twitter or Facebook, double authentication can be activated, so every time we want to log in, we are sent an SMS with a code to complete the process,” says Yago Jesús, developer of tools to protect one self in network.

Do not post personal content that might compromise you

Explicit or offensive content and images that may be embarrassing to some of the portrayed as well as contact information should be avoided.

Before accepting a friend request from a stranger, investigate. See if there are any friends or places in common, any cause that has shown interest in you or if it may be a false profile. These usually do not have photo or take only or two of spectacular good looking boys or girls. If it’s too good to be real, it probably is.

Once accepted, if you perceive something strange, block immediately

Avoid sharing data that can locate you in the real world, for example, when leaving or returning from vacations times.

Periodically review the privacy policies of the social network to control who accesses your content.

If you are already suffering harassment, you must get solid evidence to report it. “Services like eGarante allow obtaining digital evidence with legal validity to present to the police or in a judicial process and is free for individuals,” says Yago Jesus.

Do not believe everything you read in the networks

“During the American election campaign, organizations linked to political parties used them to disseminate false information about the other candidate. Facebook has already announced that it will take steps to protect its users from misinformation,” says Nogales Fulwood.


Ignore contacts you do not know. “And of course, if someone we do not know or know very little invites us to click on a link, always be wary and ignore said link, this can be a way to introduce malware in your mobile device and give control to another person, “says Yago Jesus.

Refrain from sending personal data such as passwords, bank accounts or photos, even known to known people online.

“By sending a message, we lose control over it.We never know if they will be shown or published by third parties, keep in mind that even if your mesages are safe, it don’t mean that the receiver’s phone or computer are safe from hackers,” says Nogales Fulwood.

Minors should be especially careful about the type of conversations they have with strangers , kids are targets. They may end up in groups where material or criminal information is shared.
